    Souls after death 

  • It's said that only the soul of Boss Monsters (i.e. Asgore and Toriel) can persist after death, and since Asriel is the son of two Boss Monsters, we can assume he inherited this ability, which is, theoretically, how he'd be able to reincarnate as Flowey during Alphys's experiments, because his essence would still persist in the flowers of Asgore's garden; however, when he does reincarnate as Flowey, he doesn't have a SOUL. Why? Is his SOUL not the very reason he reincarnated?

    • The thing is, Asriel tainted his soul with Fallen Child's. It's possible that unholy void of this being's soul destroyed Asriel's, leaving it in shambles when he died without bringing slaughter to the human world.
    • Boss Monster souls also only persist for a short while. You see this when you kill Toriel, her soul persists for only a few seconds before "dying" itself. So it's entirely possible that Asriel's "essence" is simply his memories or an echo of his mind or something like that, not his literal soul.
      • Basically this. It's mentioned in a library book that monster funerals involve spreading their dust on something they loved in life, which then allows their essence to live on in that object forever. When Asriel died, his dust dispersed over the flowers in the garden, which were later used by Alphys in her Determination experiments. Injecting the flower that contained Asriel's essence with Determination revived Asriel's consciousness within the flower, but not his soul, which died shortly after his body.

    • It could be just the case that these souls just are capable of changing to higher vibrant frequencies, thus vanishing quickly in higher dimensions (thus becoming out of reach, physically as well as visually). The containers for souls also have to do with that, as they are a cause of attachment. The body of a monster dissolves pretty quickly in non-living matter, allowing the soul in question to rise quickly in higher frequencies as there is no anchor to hold them down. Human souls have the problem that with death of the body, that all the living tissue needs to dissolve first into non-living matter for the attachment to go away, and when conserved it will take more than centuries for this process. We used to burn in ceremonies the bodies of the deceased in the past, so they can move on quickly. There is some Fridge Brilliance, because the bodies of the dead children are conserved in a little crypt. Without the reinforced attachment, Asgore would lose them too quicky.

    • What was the point of even telling the audience about Boss Monster souls being able to persist for a short time after death, anyway?
      • 1. World Building. 2. In one of the neutral routes, Asgore tells you to take his soul and cross the barrier, until Flowey destroys his soul anyway. If Boss Monster souls couldn't persist, this would have been impossible.
      • Because that justifies why you would specifically need to claim Asgore to escape. If it weren't stated that Boss Monsters are different from other monsters, the player would be asking "Why can't I just escape using a Froggit's soul?"

    Barrier and children 
  • There's a magical barrier separating the underground from the rest of the world. Why doesn't it prevent children from falling in? And why haven't the monsters tried climbing out from the same spot?
    • Given that it was humans who cast the spell, it could be assumed that it was made to keep monsters from getting out and also allow humans to get in...for some reason. Perhaps they didn't think that something so historic as a war would be watered down to a vague rumor over time, so they didn't bother. Toriel also mentions that while it would take seven human SOULs to break the barrier, it takes only one to cross it one way, and two to cross it the other.
    • It's mentioned that the barrier is one-way; things can go in but can't get out without fighting the barrier to some capacity.
    • The barrier turns the underground into a prison. Of course they'd want to allow anyone they deem too dangerous to be shoved in there with no chance to return. The reason children fall in is due to the negligence of the ones who made the barrier; they simply want to forget about what happened, so of course they wouldn't draw attention to it by putting guards to prevent random people from wandering over, while they didn't take coincidence into account.
    • It's also possible that the hole the eight humans fell through didn't always exist. This would explain why nobody would fall through from what seems to be medieval times to 201X...

  • Is it explicitly mentioned those six souls are belonged to children? I can't remember it mentioned in game; isn't it more plausible that there are adults and/or teenagers?
    • The coffins looked small, though.
    • They're also larger than Frisk and copy and pasted from a general, first coffin. The only difference is the color of the heart on the lids... perhaps Toby Fox just felt it too cumbersome to make them all unique?
    • I believe that if you do a second pacifist run, after Toriel tells you she knew your preference, she specifically refers to everyone that fell before you as a child.
      • I checked the Undertale text dump and couldn't find anything like that. There is an old interview of Toby's referring to them as children, but that interview is from 2013 and refers to Frisk as "some girl", so it's really outdated.
    • All humans who fell had to have come through Toriel's house first, so it seems likely that they'd be children given the box of children's shoes in her house.
    • The box of shoes might be from Chara. Toriel refers to humans who fell down to the Underground, not children specifically, unless I missed a line in the Undertale text dump. The coffins look small, but they're definitely taller than Frisk.
      • One thing that could bear considering here is to examine the items themselves that you find on your travels: things like the Tutu and the Manly Bandanna stand out in particular as childish items: it's vaguely plausible that an adult Gun-slinger would be up on a mountain (although if the gun is as old as it appears, it could be from a time and place when kids were likely, maybe even expected to use a gun), but an adult chef walking around in their apron with the frying pan at the ready? An adult woman in a Tutu (which fits Frisk)? That doesn't really fit an adult's behavior pattern. A child, though... (Then again, why would anyone be up their on the mountain carrying those items, child or not?)
      • It doesn't seem to me that there's any time and place when children were expected to use guns, and the humans are all presumed to have fallen after Chara, which was in 201X. Children who would cook often enough to run around with a frying pan and apron are pretty rare too. That the clothing all fits Frisk is a good point, although it's funnier to imagine them running around with the end of a huge apron dragging behind them.
      • Your initial statemate is incorrect, there is actually a long and often disturbing history of children being allowed — even expected — to use guns. It even happens today quite often. Many places did not always have the protective Children Are Innocent view that is prevalent today, and historically, the world has not always been safe. In fact, the period of the child with the "cowboy" hat and gun strikes me as being from quite a likely period for children to understand guns. Many would've viewed it as a perfectly reasonable thing to teach their young children how to handle firearms for their own safety. Even taking into account the fact that all the kids must have fallen after Chara did, we don't know exactly when the game is set or if it's actually our world.
      • Chara fell in the year 201X. As in, during the 2010s. Such a specific time period is given to us to make us assume that the game takes place in what is roughly the equivalent of present day in our world, when in reality it's in the future. If a child was allowed or even expected to own a gun in a time period after ours, then the kind of world the humans in Undertale live in is much stranger than first thought.
      • I find that very doubtful. The backstory speech given to you by the monsters in Asgore's home mentions Asriel bringing Chara to "the village of the Humans" and laying them to rest in the village square so he could "see the flowers from his hometown". This wording seems to imply that Chara lived in a pre-industrial society, especially since the way the villagers attacked sounds very similar to a stereotypical medieval peasant mob.
      • If that's the case, why did Chara have a relatively modern fashion sense and Asriel have access to a tape recorder? And true, communities that can be classified as "villages" aren't very common nowadays, but they do exist, especially in places far removed from society like mountain ranges.
      • There are plenty of mountain communities with limited electricity and technology, especially since many people don't live in the heart of the village proper. Besides, no one said Frisk was in America.
      • Perhaps the souls most likely to be any age are the Purple and Yellow ones. A notebook and glasses doesn't indicate youth nor adulthood, and a cowboy hat could potentially fit anyone (though a gun may actually be telling of someone older). The Green Soul's apron might be one-size-fits-all, and again, anyone could own a frying pan. The others are likely to be young based on the clothing. But imagining any person carrying the found items to a mountain with a dangerous reputation, regardless of age, is challenging to rationalize...
    • The big thing about the weapons is that it's never stated that they're 'real' items. Like real as in existing, yes, but the empty gun could just as easily be a plastic nerf, given that it's not the weapon that matters but the intent behind it. What's more realistic: someone running around in an apron with a real frying pan, or a child playing in the woods with a plastic toy frying pan and a cutesy little apron? Maybe the person with the gun was having a tricked-out paintball fight while playing cowboys. All of these things make sense if you account for children running around playing make-believe.

  • The above actually begs another question: if everyone who fell down into the Underground was a child... why? There are eight separate instances of humans entering the Ruins... how come every single one of them was a kid?
    • Kids following rumours and playing where they shouldn't, as kids are wont to do? Unlikely. It's a frigging mountain. There are technical definitions for that. That is... a very high place to climb for any reason. What was a single child doing there in the first place, let alone eight of them?
    • Could there be a more sinister reason? Maybe kids were being sent there? Any evidence of this? Asriel asks Frisk why they climbed Mt. Ebott, suggesting several possibilities.
      Asriel: Everyone knows the legend, right? "Travellers who climb Mount Ebott are said to disappear." Frisk... why would you climb a mountain like that? Was it foolishness? Was it fate? Or was it... Because you...?
      Well, only you know the answer, don't you?
    • And if that's not creepy enough, he also says that he knew why Chara climbed the mountain, and "it wasn't for a very happy reason" (the implication being that Chara and Frisk both intended to disappear somehow, whether that meant just leaving the human world, or committing suicide).
      • There's a WMG that states that the 'Abandoned Quiche' tells the backstory of Frisk inside all its flavor text and the nearby echo flower.
    • It could be that only children can get into the Underground for whatever reason. Malice is a real and tangible force in the Monster world, and adults accumulate a whole lot more ill intent by that age, so it would make sense that they'd have done something to the barrier to keep overly malicious humans out (especially considering that one could wipe them from existence entirely) and just forgotten that children can also be overly malicious.
  • So in the true Pacifist ending, you end up outside the barrier. But how? The protag doesn't die, and weren't seven souls necessary? If not, why is Asriel waiting around the underground?
    • Simple. It says specifically that "the SOULs of all monsters would be roughly equivalent to one human SOUL", or something like that, in the Snowdin Library. Asriel used the 6 human SOULs, as well as using the SOULs of all the monsters (except Napstablook), to break the barrier. The power requirements match up, and it didn't specifically say the SOULs would be destroyed in the process. The barrier was destroyed, and Asriel left with all the other monsters.
      • That's also why the pacifist run requires you spare every single monster. The power level is so uneven that the above method required the souls of literally every single monster in the underground (except one) to work. So technically you could have killed someone if Napstablook was a little more social.
      • That makes sense, but then why didn't Asgore himself do that before now? Wouldn't it have made more sense to do that rather than waiting around for another child to kill?
      • It's stated that monsters can't absorb monster SOULs (and humans can't absorb human SOULs) so that wasn't an option for Asgore. The only reason Asriel could do it is because, as Flowey, he technically wasn't a human or monster, so he could absorb both kinds of SOULs.

    Character Ages 

  • The main character is clearly intended to be a young child (how young is unclear, but young nonetheless — certainly no older than a teenager), indicated both by appearance and dialogue with various characters. And yet, Papyrus and Alphys, presumably both adults (albeit incredibly immature ones), are perfectly happy to go on dates with this child. Do monsters have different conceptions of age and appropriate age differences in relationships? Or perhaps completely different notions of what dating even is?
    • Alphys seems to be doing it largely just to humor them, probably with the intention of letting them down easy after the fact, and the whole thing was just a big misunderstanding from the start. As for Papyrus... it probably never occurred to him, and he admits to never having felt that way about the protagonist at the end of the date.
    • Yeah, Papyrus is a definite case of being his usual, odd self, and both of them were basically copying the fictional interpretations of "dating" that you get from video-games or guidebooks. (Which both of them did.) And it's not uncommon for prepubescent children to "pretend date" and gossip about "liking people" to tease one another without really understanding or experiencing the concept. I mostly just read it as a bunch of cloudcuckoolanders being exactly that.
    • Are we definite that Papyrus and Alphys are adults?
    • Um, a child being the Royal Scientist? Papyrus is maybe a kid, nay, probably, judging from his... strange, to say the least, fashion sense and his general innocence, but I really don't see how it's possible Alphys is a kid.
      • Then again, consider this: very few monsters actually refer to you as a child, and all of them are ones that logically would know what human children look like (Toriel, for example). Given how how strange monsters in general look, it's possible that they simply don't know that you're a child, not being able to judge age based on appearance.
      • But Frisk has a striped shirt, and Monster Kid implies that all kids wear it, so the other monsters should understand from this that Frisk is a kid.
      • Monster Kid is, well, a kid. And, sometimes, kids make assumptions about the world that aren't correct.
    • It's possible that 'kid' is just a classification of monster, given that monsters don't age until they reproduce and give their life energy to a child, or that Monster Kid is a child who's applying blanket logic that doesn't really work. Most likely the latter.
      • ...Except that "Only ages after reproducing" rule only applies to Boss Monsters - all other monsters age normally (though at slower pace than humans, as evidenced by Gerson). And Asriel was a child, so even they aren't born adult.

    Killing Mettaton 

  • After Mettaton's boss fight, an anxiety-ridden Alphys insists that he could've been/can be rebuilt, depending on how exactly the fight ended. Mettaton insists that it's alright and tells you something similar if you destroyed him, but in both cases, it's implied that this isn't exactly true, given that Mettaton is, in actuality, a ghost inside a robotic body, who is able to die if you destroy said body with him in it. But... What's the problem, exactly? If you "kill" the Dummy at the start of the game, Mad Dummy isn't enraged because you killed its cousin. Mad Dummy is enraged because you destroyed its cousin's house. This means that the destruction of something a ghost is possessing doesn't kill the ghost, and makes what's implied to happen to Alphys if you destroyed Mettaton make a whole lot less sense. She literally could just build another Mettaton.
    • If you attack the Dummy at the beginning of the game and continue with a No Mercy run, by the time you meet the Mad Dummy, it's so furious at your actions that it bonds with the dummy it's possessing, allowing you to completely kill it. Mettaton wanted his robot body very badly, to the point where he abandons his cousin and friend despite his promises to not do so. Presumably his strong feelings towards his new body (the humanoid form seems to come out of his rectangular body) were so strong that he bonded with it, allowing you to kill him as well.
    • Alphys says this after "killing" him (by shooting his heart) in a Neutral or Pacifist run, but he is only out of batteries. She is able to fix him, and Mettaton is completely fine when you find him in front of his and Napstablook's houses during the Playable Epilogue.
    • Don't forget that if you try to kill Napstablook in the prologue, he'll only lower his HP out of politeness and tell you that ghosts can't really die (at least not from physical damage), and you also can't hurt the mad dummy unless you turn their magic attacks against them for the same reason.
      • You can't hurt the Mad Dummy, but you can kill the Glad Dummy normally (and in one hit) in a No Mercy run, because at that point, he's not a ghost anymore, he's found a body to permanently bond with, which you can kill.
      • The above is also the reason it's possible to kill Mettaton NEO. He's bonded with his body. He gave up the functional immortality being a ghost provided in exchange for becoming corporeal.

    The Abandoned Quiche 

  • During the date with him, Papyrus mentions Sans baked a quiche with a "sugary, non-egg substance". That one was most likely a pie, but in a secret room you find an "Abandoned Quiche" item sitting on a bench, and the Echo Flower next to it states "I just wasn't ready for the responsibility". The descriptions for it highlight how traumatized the snack feels. If Sans was the one who cooked and brought it there, then who was he talking with?
    • Some have speculated that that flower is a little meta, and hints at Frisk being an abandoned/neglected child. In that case, you shouldn't think about it too much.
    • A quiche with a "sugary, non-egg substance" isn't a quiche. It's a pie.
    • The point is that by talking about quiches in the first place, Papyrus implies Sans has made one in the past, which he could've abandoned there for whatever reason. It being a metaphor for Frisk and/or Chara being abandoned is also interesting, however. Of note is that Toby mentioned finding an abandoned quiche under a bench back in 2013. It could simply be a joke on how we can feel intrigued upon finding lost objects but never learn who owned them.
    • It's never actually mentioned that Sans has ever made a quiche or even knows what one is. In fact, it's mentioned that he rarely ever cooks, and the one time Papyrus recalls him cooking he made a pie which Papyrus simply mistook for a quiche because Papyrus is a Cloud Cuckoo Lander. In reality, the only character who is ever shown to definitely have any idea what a quiche even is would be Papyrus himself, making him, if anyone, the most likely former owner of the Abandoned Quiche. If this is the case, then both the abandoning of the quiche and the explanation of "I just wasn't ready for the responsibility" apparently given to no-one in particular can be chalked up to Papyrus being melodramatic and strange.
    • Papyrus's dialogue about a quiche was supposed to be a joke about him not knowing what a pie is. Since that alone doesnt indicate that other monsters in the underground would not know how to make a Quiche, its very likely neither Sans nor Papyrus have anything to do with it, and it's simply a coincidence that one appears somewhere else in the game. This is supported by the fact that echo flowers are capable of recording characters' Voice Grunting : The flower next to the quiche doesnt sound like Sans or Papyrus.


    Relative Age of Skelebros 

  • Is there any instance in the game which states whether Papyrus or Sans is the elder brother? I've seen people online fully convinced one way or another, and even referring to some line in the game (without ever quoting it), but I don't recall it ever being confirmed either way.
    • Maybe they are twins? How do monsters reproduce anyway? I won't be surprised if they were 'born' at the exact same time.
    • Sans could be mentally older since he was aware of time loop (and who knows how many times the loop happened).
    • To answer your question, no. I don't believe there is any text in the game that explicitly states which one of them is older. And they both have traits that could make it go either way — Sans is more savvy but also looks up to Papyrus and thinks he's cool, while Papyrus takes care of Sans and encourages him but acts more innocent and naive. Good arguments could be made for either one of them being the elder...or they could just be twins.
    • In a recent twitter post about a hypothetical Japanese localization, Toby said that "Papyrus would definitely use 'aniki'". "Aniki" is a honorific towards older brothers, so it might mean that Sans is the older one. Then again, it might be that Toby meant that this would be the case if Papyrus was younger.
      • Considering the tweet he was replying to didn't specify which of the brothers, it's probably safe to assume Papyrus is the younger brother, as Toby seemed to specifically point him out.
      • Or he just thinks of Sans as older, because at least mentally, he is. They might both be incredibly strange, but Sans is easily the most 'normal' of the two, and... well... It just makes sense for it to go either way, and Sans may be of equal age to Papyrus, but at the very least, he's mentally an adult (sort of, anyway), while mentally, Papyrus is a child.
    • In the Japanese localization, Papyrus consistently refers to Sans as his older brother.

    About the True Pacifist Ending 

  • Let's be honest, that is one massive Fanfic Fuel. But how long has it been since the war between humans and monsters? The intro shows some sort of medieval-ish setting while the true ending shows a modern, present age with cars and skyscrapers. This also brings question on monsters ages (though Asgore and Toriel are explicitly stated to be immortal without any biological children). Also, how did monsters integrate on society? Did the war happen so long ago that humans don't even care about it anymore? If yes, then again, what about their ages?
    • It's implied that it has been long enough for several generations (Boss Monsters aside) of monsters, quite a few monsters don't even recognize that Frisk is a human, some just think they're a type of monster they haven't seen before, the rest presumably only have an idea from what they've learned in school. Besides Asgore (they never say if Toriel was already the queen when they were sealed up), the only other character we see who we know to have participated in the war against humans was Gerson, which A.) He's a turtle monster, and B.) even despite being a turtle, he's visibly an old man. As for monsters and humans, look at today (since the ending takes place in about this time period); we're a lot more tolerant as a society, not to mention critical of our past because we're aware of Written by the Winners. It wouldn't be too hard to assume that the monsters' return would be handled diplomatically and humanity would listen, acknowledge, and be penitent of the fact that they were the ones who struck first. There's also the fact that they show a lot of stuff in the ending that's time-sensitive (Papyrus driving a car, which takes at least a few months of learning to get a license, Toriel opening a school, which has a hilarious amount of bureaucracy behind it) that implies there's a several-month time skip while humanity gets used to sharing the planet with monsters... which just adds more Fanfic Fuel about the interim.
    • When you talked to everyone in true pacifist route, Catty and Bratty mentioned the monsters had been trapped for a millenia. It could be an exaggeration, though.
    • I take it that time in the monster world passes slower than in human world, as the war may have been roughly a few decades, whereas in monster time, it was about a millenium or maybe the monsters interpret time differently.
      • This would especially be the case if Flowey's resetting shenanigans only affected inside the barrier, causing a sort of stuck state of time until Frisk came along.
      • And keep in mind that Frisk's presence led to even more resetting/reloading shenanigans (at least one reset/reloadnote  is mandatory to reach the True Pacifist ending, and this assumes a perfect Pacifist No Death Run (anytime Frisk dies causes an automatic reload from the last save)).
    • How the hell did Toriel have a tape recorder and VCR before the monster-human war, and equally how do a lot of monsters have TVs, then?
      • Bratty and Catty mention that before she became very reclusive, Alphys used to spend a lot of time dumpster-diving with them. Presumably, she (and others like her?) reverse-engineered and recreated human technology for monster use.
      • Where does the game indicate Toriel had a tape recorder before the war? The tapes were between Chara and Asriel, likely placing them in the 2010s. In our world, a tape recorder is actually somewhat obsolete for that time.

    The Fallen Child 

  • After finishing the Golden Ending route and looking up a bunch of info online, there's really only one thing puzzling me... who or WHAT is Chara? Like...I don't know where to start. We're not told if they really hate humans, and if so why, and we also don't know how long they were planning on tricking a monster into taking their soul. The question is, how are they able to possess/influence Frisk? That kind of ability isn't really elaborated on IIRC, and if Chara is (as they say) some kind of demon that appears when their name is submitted into the naming screen, were they always that way? Guess it's time for some WMGs... though the ambiguity of it all really adds to the freakiness of the character.
    • The general consensus seems to be that Frisk and Chara merged somehow, possibly even sharing bodies — the place where Frisk fell is Chara's burial site and Frisk's starting armor is a bandage, which you can also find in Chara's coffin in the castle. One interpretation is that Frisk actually died in the fall and persevered due to determination (similarly to Flowey), which would create an opening for Chara to latch on to the body, if their consciousness was still around.
    • No, Frisk's bandage is clearly described as an adhesive band-aid type when equipping it. The ones in Chara's coffin are mummy-like. They're different types of bandages. Chara most likely latched onto Frisk when Frisk landed on Chara's grave, the flower patch in the Ruins. I believe post-death Chara might be a being similar to Flowey, with memories but no soul. And just as Flowey is not a whole representation of Asriel, the Chara we revive with violence in No Mercy is probably not what they were like in life. Their memories guide you on your journey. It's been speculated that Chara is also the white text narration — because Frisk wouldn't know anything about the monsters (CHECK) or how to read monster language, but Chara certainly would.
    • This has bothered me since I learned about the Genocide route after completing the game, and I'm still not sure exactly what is up with it. Of what we see and hear of post-mortem Chara, they are pretty messed up, but not straight up psycho — they see poisoning as a joke, but don't seem to wish for Asgore to die by it, they just see it as a joke. Likewise, when they commit suicide by buttercups, it's mostly implied that they do it to further a plan to destroy the barrier with Asriel, something that doesn't happen because Asriel can't stomach killing innocent humans, and goes back to the Underground instead. The Chara we get in the game does seem to be a spirit inhabiting the body of Frisk (however that works... I mean, when did we learn that non-monster ghosts existed?!), but it's not the evil demon that Chara may become in the Genocide playthrough; they are simply the child they were before, a bit malevolent, but ultimately still with the Underground's best interests in mind. So, if you go Neutral or Pacifist, the Player and Chara guide Frisk together, you by guiding Frisk in conversations and protecting their SOUL, and Chara by their knowledge of the Underground and by dropping small hints through the white text. However, should the Player's Killing Intent be so aggressive that it borders on insanity, Chara's evil side takes more and more hold, to the point where Chara essentially becomes pure hate and killing intent, rather than the nuanced specter they were before — basically the way Asriel only shows up when shown a lot of mercy and happiness, and stays Flowey if they are not. Flowey and Frisk are one large expy on each other — both are controlled by a malevolent creature (a flower with no SOUL and a human with no SOUL), both have Determination, both have genuinely merciful entities in them (Asriel and Frisk). The only difference is that Frisk has You, the Player... And that can be both bad and good.
      • Alternatively, Flowey is just Asriel without virtue and Chara and Frisk are just the player (as they express themselves in the game with a little bit of vague backstory to justify the background information they know). Chara is more or less positive and involved in things beside murder, because you are.
    • In the epilogue, Asriel tells you that Chara hated humans and was "not the best person." They were the one who controlled their shared body to cross the barrier and walk into the human town, but Asriel was able to keep them from killing anyone and return underground.
      • As with the rest of Chara's actions, this is subject to interpretation. Chara left a life where they had everything, in a way which they knew would be excruciatingly painful, making a pact with Asriel to procure the human souls needed to free Monsterkind. Asriel changed his mind and refused to fight despite the people of Chara's village inflicting deadly wounds upon him. We don't know if Chara was a cold-blooded killer. It seems likely that they were mistreated by humans and cared for by monsters, but we don't know whether they actually hated humans, wanted their feelings to be that black and white, or even just wanted to make their allegiance to their new people clear.
    • Determination, even from an outside source, has been shown to raise the dead (specifically with Flowey and the Amalgamates), and it also seems to cause their "spirits" to inhabit the nearest viable object (such as a flower, in Flowey's case) — it's possible Frisk simply had so much Determination, their presence in such close proximity to Chara's body allowed the Fallen Child's spirit to resurrect and the closest object at hand for said spirit to possess was Frisk.
    • In a second genocide ending, Chara refers to itself as a demon that comes when people call its name. It may be that Chara never truly WAS human to begin with (which would go a long way to explaining their hatred of humanity) and only impersonated one. It latched onto Frisk when they landed, hoping they would be a suitably violent individual — in the event that Frisk is (the player following the genocide route), that violence empowers Chara and eventually allows them to take complete control.
      • Alternatively, it could simply be an expression. Someone willing to commit suicide through a method as painful as Buttercup poisoning cannot possibly have a healthy sense of self-worth, and the phrase "You Monster!" doesn't really work in Undertale. So what else do humans consider to be the antithesis of mercy and love? Demons. Heck, it's possible that even the suicide plan was half motivated out of a fear of destroying everything they touch. Chara couldn't have been more than 12 years old or so when they died. Can you imagine what would make someone who hasn't even reached their teenage years try to kill themselves, and then try to do so again, in an agonizing method? And if we go by the theory that they're corrupted by the genocide run, then a 12-year-old that already has some serious issues and disdain for humanity, being brought back from the dead and forced to watch in 1st person as a human mows down not only the entire underground, but also every single member of their family, and they have to watch their closest friend die all over again. It's frankly impressive that they can even speak complete sentences after being subjected to that.
      • But Chara must have originally been human at some point, because it's specifically stated that you need a human soul and a monster soul to cross the barrier. When they died, Asriel had to have absorbed Chara's human soul and used that to cross over and take back their body — it's something that simply wouldn't be possible if they didn't have a human soul. What I really want to know is what happened to Chara's soul after that, because it's not in the coffin at the end and I'm pretty sure Genocide Chara doesn't have it — they have the six Asgore collected, but they want yours as well.
      • It just says you need the power of a human SOUL, not the SOUL itself. Is it possible that demonic SOULs are just as strong (or even stronger) than human ones?
      • Personally, I think the Fallen Child simply died in the fall, and Chara took over their body and absorbed their soul. Those golden flowers that break Frisk's fall wouldn't have been there at the time. Anyway, they go over this (briefly) in the game: When Asriel came back from the surface and died of his wounds, his remains, dust and soul alike, scattered into the seeds he carried back with him, and eventually grew into the flowers that would eventually become Flowey and the flowerbed itself the thing that breaks the future fallen children's fall. We don't actually know what humans do with their dead in this world, though, so we don't know what happens to their souls except that they can be contained and will disappear if they aren't. Most likely it escaped with Asriel's when he died, leaving the purely-demonic entity of Chara to haunt the flowerbed, waiting for its next host.
      • That wouldn't really make sense, in that then the demon would have easily been able to manipulate Frisk into a less than savory route. Even if we believe that the demon had trouble taking over because Frisk was still alive, making this theory plausible, there's not as many clues leading to it than there are clues leading to the "Chara has malleable morals and the player teaches them right from wrong" theory.
    • "The demon that comes when you call their name" is a programming pun. The game needs a name for the variable used to represent the player character. (Because the player can enter different names for their character, using that would require rewriting the code for every game.) "Chara" is the name of that variable. (Presumably short for "Character".) When you change the stats or otherwise do things that the game records, you are changing "Chara". When you increase LV, you are literally increasing Chara's Level of Violence. (This is why they say that they are the source of the feelings you get when your stats change.) Whoever they where in the backstory, in-game Chara is the player's digital reflection.

    Toriel fighting to the death 
  • Why does Toriel allow you to kill her, when Asgore, who is explicitly suicidal, holds on after a similar Critical Hit?
    • Toriel wants you to prove you're strong enough to survive outside the ruins, and even if you're willing to wound, that only makes a few enemies back off, she wants you to prove you can kill if you must. As for Asgore, he's going to die anyway after the final blow, so he chooses to hold on so that he can tell you that you can take his soul so you can leave before it disappears; he isn't expecting mercy.
    • That… seems really extreme, especially since the monsters aren't nearly that violent and tenacious. It's odd that she's willing to kill herself just to prove a point, especially since the trauma it would inflict on a small child almost certainly outweighs any benefit to survival. As for Asgore, he kills himself if you go back after killing Flowey, which implies he would have survived otherwise. So, again, even if she was as suicidal as Asgore, it's inconsistent that he clings to life but she doesn't, especially when she has a lot more to live for than he does.
    • It's possible that Toriel simply has some skewed visions on how the rest of the underground works. She had exiled herself to the ruins for years and is aware that all the humans to fall into the underground before were killed after leaving the ruins.
    • Another possibility could be that the difference between Toriel and Asgore surviving isn't due to their differences, but because of the child's/player's emotions at the time. Assuming they're not on No Mercy and killing them in one hit, then you're likely trying to spare them by weakening them with necessary force. With Toriel being the first major boss, no matter how weak she gets, she shows no sign of giving in. Combined with the player likely not wanting to fight her in the first place, wondering why she doesn't just give up leads to a moment of desperation and rage which, because monsters are susceptible to the emotions of their assailants, causes the suddenly fatal strike that ends her life. For Asgore, on the other hand, because it's the end of the game, you are far more experienced and in control of yourself, even if you haven't killed anyone. You know what's at stake now and are more able to control yourself than when you fought Toriel, meaning you are successfully able to hold back within an inch of their life now unlike before.
    • Toriel might just not be as tough/determined as Asgore. Badass as she is, Toriel hardly seems to have used her skills since isolating herself, except to cook and start fires (in the fireplace, of course), whereas Asgore likely trains with his royal guard and has proven to be better than Undyne. Asgore also has very good reasons not to die and is clearly a very dedicated individual, whereas Toriel already seems to have near given up on a lot of things.
    • Toriel's dialog during the fight implies that she's nearly a Death Seeker at that point due to her failure to save the previous six children; discovering that she can't even save you is enough to push her over the edge. Also, she does linger on for a short while, long enough to give a few final words... but it seems likely that she didn't want to survive after letting the final child go to what she believes to be certain death.

    Vegan Cake 
  • When you're making the cake with Mettaton, you gather eggs, sugar, and milk to make the cake with. Mettaton then reveals that the secret ingredient is a human soul, but Alphys calls and suggests a substitution in the recipe in case someone is vegan. Mettaton has an artificial soul substitute, but... eggs and milk aren't vegan. Nobody mentions this.
    • Firstly, monster foods are implied to be made of magic and work differently than human foods. The eggs and milk were also not properly refrigerated. Since monster food doesn't come from animal products in the first place, it's possible that the word vegan means something entirely different, or that vegan milk and eggs can exist. Secondly, the only people who would have said anything are Mettaton and Alphys. It's a bit subtle, but Alphys spends most of Hotland on the verge of a panic attack (possibly leaving to go have a panic attack at a few points). Mettaton, meanwhile, is just going along with whatever Alphys wants while putting his own flair on things. Viewers might interpret it as a bit of a gaffe, but not think enough of it to bring it up.
    • Maybe Alphys meant to say vegetarian, but fudged her line and said vegan instead. Note how Mettaton flatly repeats the word to her before going on with the show. (Considering her nervous demeanor and Mettaton's attempts to make Alphys appear to be your savior, albeit with a gradual loss of patience, this is more likely than not what's going on.)
      • Pretty much, it's just another flubbed attempt to appear to save you and Mettaton immediately rolls with it once he gets over the shock, trying not to dwell on it and hoping no one notices. Other similar flubs include disrupting you while you try to disarm the lasers, and when you fail the tile puzzle, you can see Mettaton slowing the walls of fire and stalling for time because Alphys missed her cue to disable them sooner.
    • For that matter, where is Mettaton getting this Human Soul Substitute? Who figured out what a human soul tastes like and then artificially reproduced it? When did it become a cooking staple?
      • Well, when you do the True Lab bit, you find out that Alphys has been doing experiments with the human souls, so one of the first things she probably tried was recreating an artificial soul so they could break the barrier without having to wait for another human to fall in. Obviously it didn't work, but maybe then she somehow found it was good in cakes?
      • Or maybe there was no human soul in the actual recipe. Examining the substitute after the cooking show reveals that it's stuck to the table. It could have been just another artifact on Alphys' "quest" to be your hero.
      • It's a cooking show. He baked it beforehand, and when is the last time you've seen a normal cake require a SOUL in the recipe? He just wanted an excuse to look like he was trying to kill you.

    The Mouse 
  • How exactly do you know the mouse will get the cheese one day? Are you from the future? In some places, it's been left out so long, you could just as easily guess the mouse never wanted it in the first place.
    • It's a running gag that's just saying that the mouse can do anything if it's determined. Don't think too hard about it.
    • The line is that the mouse may get the cheese. You're hoping for the possibility, not knowing it for certain.
    • And if you backtrack after finishing the True Pacifist ending, you'll find out that, yes, indeed, the mouse got the cheese. Even when it was trapped in a crystal or in an electronic safe.

     Determination & Saving 

In the No Mercy run when Flowey talks about how you falling into the Underground caused his ability to Save being taken and given to Frisk, the implication is that whoever is the most determined is able to utilize "Saving". But how far is that area of judgment? Like, what's the rule on determining who gets to save, and does it affect the whole world or is it only in a given area? Because that implies that some child is the most determined being in the entire planet.

  • My guess it only works in the underground. Reason as follows:
    • Flowey only failed to save AFTER Frisk came to underworld, not before.
    • If Frisk could SAVE before they fell, they could simply reach their SAVE files. No need to go through the barrier.
    • The barrier separated both worlds. Monsters cannot save. Frisk is the only one able to save because they are the ONLY human in the underworld.
    • Flowey could originally SAVE because he was Asriel and Chara's fused conciousness, so to speak. Once Frisk fell into the underworld and Chara latched to them, Flowey was reduced to Asriel only, and as such lost the perks of the human/monster soul fusion.
      • Except not quite. Flowey could SAVE because Alphys injected determination extracted from the human souls into a flower that was imbued with Asriel's essence. That's also the only reason he's alive. Flowey never had Chara's consciousness; both Chara and Asriel were killed, and only Asriel was able to be resurrected because it was his body that turned to dust and spread over the flowers.
      • Also if the "SAVE only works in the Underground" thing is true it begs another question: did Flowey get his ability to SAVE back after Frisk left, and if so, would that ability only exist in the underground? Can he not reset the world above, too?
      • Who says he'd reset to his own save rather than Frisk's last save, when the barrier was already broken? Also, the dialogue that comes up when you try to replay the game after a True Pacifist run makes it pretty clear that even if he could, he's not going to.
      • Well, if humans have powerful determination, wouldn't that mean that humanity as a whole has greater powers to load and save? Flowey would have to contend with the whole of human determination, and thus his save scumming powers would be worthless. Humans could revert back any changes he made immediately after he made them, and even override any world changing revisions. Heck, you the player, being sufficiently determined, can override another human's powers by undoing the No Mercy run. So the underground is just this period of time in a place where humans other than Frisk aren't aware of any changes (not being involved) to the timestream, so he and Frisk have some flexibility in manipulating time just in the underground. Once Frisk showed up, Frisk became a static, constant inevitability, so Flowey couldn't make any changes that could have prevented Frisk from showing up, nor undo anything Frisk has "saved", so he effectively lost his powers to Frisk. He can't make changes until he becomes stronger and can force his own inevitability upon Frisk, and even then isn't safe from Frisk nor the Human souls' collective power of determination. Having determination might mean being able to lock out other beings from possible timelines — there's never a possibility of Frisk dying, because we and Frisk don't allow it, and Photoshop Flowey can lock us out of defeating him at first by preventing that possibility from occurring via save states, which is stopped by us making it so the only possible outcome of the fight is him being insta-destroyed any time he tries. In conclusion, the underground is a bit like a timey wimey wibbly wobbly Schrodinger's box as far as time is concerned, as until the whole of humanity looks upon it, anything can happen in there as far as time travel, but once enough observers look at it, it collapses into inevitability.
      • As for why you can reset the game to a no mercy run after the monsters escape to the Human world, you have to realize that you're not an Undertale human, you're a Real human, and your powers of determination make you more like a kind of god that can overrule anything and even manipulate the game's code, so not even the whole of Undertale Humanity can overpower your determination.
  • Or you simply ARE the most determined being on the planet. Imagine: You have Frisk's determination, plus Chara's, plus, yours as the player. That's 3 people's worth of determination.
  • I'd say the power of Determination only extending to the Underground itself makes the most sense. Otherwise a being like Frisk/Chara/Player would likely never come into being unless Flowey allowed it, as Flowey would just keep resetting over and over and over again preventing time from ever progressing. It also makes a great deal of sense as the Underground has been the home of monsters for hundreds of years. The Underground being permeated with so much magic from their presence could be the reason that the power of Determination and all its effects can even actually happen.

    "Fallen down" and the experiments 

  • So the notes in the True Lab, Mettaton's diary entry, and a book at the Snowdin Library inform the player that monsters refer to dying as "falling down". We know that monsters immediately turn to dust when they die except during rare cases. However, one of Alphys' notes in the True Lab mentions that the monsters she had received for the determination experiments were comatose but that they would soon turn to dust. We can assume they were alive but barely. What kind of power could cause multiple monsters (including those who may have once been members of the Royal Guard) to go into a vegetative state? Was it disease? The work of a previous fallen human?
    • Maybe falling into a coma before dying is the natural way monsters die? Murdering any monster in cold blood makes them die quickly, yes, but who's to say dying from something like old age is the same on their bodies?
      • Bingo. A Dummied Out history book entry explicitly defines a monster falling down as lying down completely immobile when they're about to expire from old age. Granted, the fact that it's removed from the final game means it's not 100% guaranteed to be canon, but it's the best lead we have regarding what "Fallen down" means.
    • It could have been a more literal event like a cliff collapsing with a group on top, causing them all to "fall down" and go into comas. Old age sounds unlikely just because it doesn't explain why so many of them were around at the same time in that state to be used in the experiments.
      • Many monsters in Snowdin talk about overcrowding as a serious issue in the Underground, and in both the Ruins and New Home there's evidence of massive cities that Frisk just doesn't get to walk through. In a city that size, it's not any wonder that there were that many people around who were old enough to die, particularly if they were dying of a lack of hope as a below commenter mentions.
    • Based on the fact most of the 'fallen' monsters are adult characters' parents, it's probably a euphemism/literal description of the short period of time before a monster dying of age or illness dusts. Interpreting it as a euphemism for death/impending death also makes the implications of the title 'fallen' child... interesting...
    • It's implied through one of the entries that monsters were falling down due a loss of hope. Monster souls are said to be composed of love, hope, and compassion. The order from Asgore to Alphys to conduct experiments on their bodies took place during a time when it seemed like the situation underground was never going to be fixed, so various monsters succumbed to hopelessness. In which case, they literally died of a broken heart.

    Lemon Bread 

  • The forms the Amalgamates take while hiding in the True Lab seem representative of their past lives. Snowdrake's Mother assumes the form of a fridge, possibly representing her hometown (Snowdin) and the fact that she was "fridged" for the narrative. Endogeny is found in a foggy room with flecks of snow-like ash floating in the air, also reminiscent of Snowdin. Reaper Bird consisted of three unhappy, existentially weary monsters and reveals itself in front of a wall of mirrors. However, Lemon Bread is unusual in that she disguises herself as a save point, an object used by only those with the ability to save. Lemon Bread is also the only Amalgamate and possibly the only monster that speaks the Arc Words, "But nobody came". If the Amalgamates’ mannerisms and dialogue are indicative of their past lives, then there’s the implication that one of Lemon Bread’s host parts (Shyren’s sister, Aaron’s sibling, or a relative of Moldbygg) somehow encountered Flowey or was familiar with determination/the ability to save. The question is: which one and how much did they know?
    • Given that Shyren seems to be the one who seems to be given a somewhat significant presence (her place in Mettaton's band at the end, Undyne personally giving her piano lessons, the fact that if you do the right actions you two can have a whole concert with Sans even selling toilet paper tickets/conversely, if you've killed Papyrus, "a hooded figure watches from a distance"), I would put my bet on Shyren and her sister.
    • Lemon Bread appears in front of the Determination Draining Machine; she's somehow foreshadowing Flowey's fate either through coincidence or finding the information.
    • Let's not forget that Flowey was created in the same facility in which the Amalgamates lived. There's no reason Lemon Bread's COMPONENTS had to have ever met Flowey, but it wouldn't have been difficult for Lemon Bread herself to meet him, and with how deep in despair Lemon Bread is ("Welcome to my special hell") latching onto that phrase wouldn't be out of character.
    • All the Amalgamates were injected with determination. It's why they're still alive at all. Alphys' notes describe the process. It's reasonable that they could be aware of save points and other meta aspects of the setting because of this, even if they were never powerful or coherent enough to make use of it themselves.

     Purging The Fallen Child 

  • The way I see it, there is only one thing that is really left to be stopped when it comes to a True Pacifist run — the real threat to Monster and human society, as long as it can continue to influence those who fall within Mt. Ebbot — Chara. Why don't we get the chance or earn the right to bring happiness to Asriel and protect both worlds by being given the right to expel and remove Chara from harming other worlds, and cause them to be destroyed or even partially redeemed? That way, no world can ever experience the intense fear and death that occurs from his influence.
    • Because that would dilute the meaning of the game's theme. The only way you can protect other worlds from Chara is by not being Chara. You are the one who brings Chara's influence into the world; in a purely pacifist playing of the game, Chara does not appear except as a memory. That's why No Mercy has an irreversible effect: Even if you go back and try to do everything right, you've proven that your soul contains the essence of Chara, the willingness to kill everything because it's all just a game. And so the game shows that Chara lives on within you — if you are capable of killing all of the characters in Undertale, you are surely capable of annihilating other worlds in the same way, bringing Chara into those worlds "just to see it happen".
    • Yes, I cannot stress this enough. The player's actions cause Chara to warp into a world-destroying Eldritch Abomination at the end of No Mercy. Chara outright says this to the player: "My 'human soul'. My 'determination'. They were not mine, but YOURS." and "Why was I brought back to life? YOU. With your guidance, I realized the purpose of my reincarnation." Chara lingers in Frisk as a neutral presence from the beginning of the game. They are with you the entire time and follow what you do. They never turn violent unless you choose to kill. However, Chara only becomes something terrifying in No Mercy because the player tells them murdering people to become strong is the only option. You save Asriel in Pacifist with Chara's memories, but you also save Chara themself when you show them a happy ending without a need for violence. One of Undertale's themes is that no one is past redemption, so it doesn't really make sense to treat Chara as some absolute evil. If anything, YOU are the true threat to a Pacifist ending.
      • But that's just it: Asriel himself, by his own admission, claimed that Chara wasn't the happiest or the nicest person when it came to the subject of humans. While we never really understand the reason why, or the reasons why they poisoned them and Asgore — which I've seen argued and implied in-game as intentional in order to become Godlike — it didn't paint the greatest picture of a person who is capable of redemption, as you claim. If they rest inside the player — even if the player's actions ultimately are what cause their revival — it was Chara's influence that could have made fighting a reasonable response in the first place...and would be something that Frisk, by the theme of the game, should be able to remove from themself. In that sense, it fits even better: No one is beyond redemption? How about yourself, and the monster you helped create?
      • Well, no, because "No one is beyond redemption" is not a theme of the game. The only character who actually gets any form of redemption is Alphys, but the narrative never actually condemns her to begin with. The few characters who do anything really wrong have to live with the consequences of their actions, and so do the ones who had awful things happen to them that weren't their fault: Asgore made a rash decision in a fit of grief and anger but stuck with it out of cowardice, and it cost him his relationship with his wife. The Amalgamations are never restored to their full selves and the ones that get to go home to their families are only going to one family, that of the most dominant mind in the hive (Snowdrake even mentions that he doesn't mind that his mother is sixteen other people, he's just happy to get his own mom back), while the others are just #### out of luck. Burgerpants will be Burgerpants forever. The souls of the other humans are freed, but they're still dead and no one knows what really happened to them. And then Asriel, who you make all the effort in the world to truly redeem, still has to go back to being a soulless flower. There is very little redemption in this story, but there is a lot of forgiveness, and all the things that point to Chara being a horrible person are their own efforts, not bad circumstance, or emotional turmoil sustained by weakness, or an accident. Chara is a selfish, greedy, hateful little ####, and if you go through the entire long, tedious process of murdering damn near everyone in the game, then you're proving that you're beyond redemption to begin with, and Chara, being either not human at all or just a ghost controlling Frisk, has no one left alive to forgive them. If you do a Genocide run, it doesn't matter what your reasons are, because you had to know exactly what you were doing and why it's wrong... unless you think it's not that bad because you can restart and bring them all back to life, because it's all just a game, because you couldn't not get all the endings. A tainted Pacifist ending is the consequence you get to live with for thinking that you could just skirt consequences altogether, and since you're the single most powerful entity in the world of Undertale, you have no one to blame but yourself. Asking "Why can't you just purge Chara's influence?" is like asking "Why can't God go to confession?"
      • Beg pardon? Redemption just isn't about good and evil, it's about personality, and every single named character is redeemed about something over the course of the game. Toriel and Asgore both directly attempt Suicide by PC, Sans is redeemed (mostly) of his depression, Alphys has her dark secret, and Undyne has a goal that requires the death of an Innocent Child. In each case, you force someone to do something they don't want to do (or the reverse). While this doesn't solve Chara, it does beg the question why you can't force Toriel and Asgore to meet with Asriel one last time.
      • Undertale's entire story is about moving on. The reason Chara is such an antagonist is partially because she's the result of the player refusing to move on — how many people do you know who did the Genocide run first? Very few. Most only do it because they want to 100% the game, which Sans calls them out for. After a true Genocide run, Flowey actively tells the player to move on instead of endlessly replaying the game. Asriel himself is only an antagonist because his love for Chara and desperation to stay with them — i.e., his refusal to move on — have warped him into a very desperate and malicious version of himself. Toriel and Asgore both need to move on from their guilt regarding the death of their son, which has forced both of them down dark paths that lead to their toxic tendencies. To have them finally reach salvation and drag them back into the dark by telling them that their only son is now a twisted form of himself unable to feel love and compassion and there's nothing they can do about it? Even he doesn't want that. Yes, in the real world, parents would probably want to know their child is alive, still. But this is a game, and his refusal to see them is less actual parent-child relations and more narrative symbolism.
      • Taking another tack... let's backtrack and say it did happen, and Chara gets expelled from every possible world. What other game do you know of where an omnicidal childlike murderer, who destroys entire worlds out of boredom, just got locked out of every other world and timeline on grounds of ruining too much?

     Everyone deserves MERCY...except Chara. 
  • Why are there so many entries talking about Chara being a demon, a sociopath, or, to quote the above, a "a selfish, greedy, hateful little ####" who likes to kill things For the Evulz? Even Asgore doesn't receive that treatment, and he's killed six human children! The only person Chara kills, at least voluntarily, is themself. The other kills that can't be accounted for by you, the player, (such as Sans' death) only happen after you, the player, have already killed their mother Toriel as well as every single monster you come across, raising thier LOVE to the point where their actions don't resemble who they really are.
    • Because Chara tried to hijack their best friend's body to slaughter a bunch of people, with the ultimate end goal of restarting a war in the hopes of wiping out humanity. (That all happened before the player or Frisk showed up, so neither of them can be blamed for it.)
  • Not to shove a way of thinking down anyone's throat, but the Narrator Chara theory just seems to make the most sense. Chara falls into the Underground, implied by Asriel to be a Bungled Suicide. They're taken in by the Dreemurs and befriend Asriel. The "buttercups/cups of butter" incident was an accident. Chara may have "laughed it off" because laughing or smiling is thier coping mechanism, which is a common theme in the game (multiple characters laugh when they are about to die, and then there's Sans, Snowdrake, and his father, who are all implied to be Sad Clowns). Additionally, it could be that they are not conciously smiling, as agony resembles smiling despite being the exact opposite.
    Of course, they plan to get 6 human souls to break the barrier. Obviously, this is bad. But due to the nature of the barrier, it seemed like they had no other choice, as the way Asriel broke the barrier in the Pacifist Route was unprecedented. But this is usually where people begin to think of Chara as someone who only wants to kill humans because they hate them. But if Chara only wanted to kill humans, why didn't they just kill one of the Dreemurs and cross the barrier?
  • Thinking of Chara as a demon or a violent sociopath just raises more questions than it answers. If Chara isn't human, why could Asriel use their soul to cross the barrier? If they're a sociopath, how can Flowey recognize Frisk as Chara in a Pacifist route? If they wanted to kill everyone, why didn't they just kill one of the Dreemurs and use thier boss monster SOUL to cross the barrier? Why would they put in time and effort to make sweaters and drawings for thier adoptive parents if it was all an act?
  • Every character in the game tries to kill, capture, or lie to you in order to get what they want. Yet, everyone is still given MERCY, even Flowey. Why not Chara?
  • Honestly I've always gotten the impression that the hatred for Chara some people seem to have is a bit forced. To me it more seems like they're pushing responsibility onto Chara. The player is the one ultimately responsible for a genocide run happening, and yet time and time again people seem content to push the blame completely on Chara when given an out.
    • But why turn Chara into a scapegoat? True, there's not much information on them and they appear to be villainous at first glance, but considering that literally every other character in the game is forgiven by the fans, with some even going above and beyond to do so, it's odd that Chara of all characters isn't considered the same way.
    • To be fair, Asriel himself (who was Chara's best friend in life) describes them as "not the best person" in the Pacifist ending, in which the player didn't "make them" do anything. They also were described as hating humanity, and killed themself in a pretty awful way for the sake of breaking the barrier. This is... not exactly the behavior of a normal child, by any stretch. While yes, they're probably not as over-the-top evil as a lot of people say, they're not completely innocent, either.
    • Turning Chara into a genuine antagonist at all is a cop-out that pointedly ignores the entire arc of their character. They're literally just a player-insert character. That's why they're named Chara. All of their bad actions are your bad actions. They are a mirror of you.

     Ruins door conversation 

  • At what point in the timeline of the game does Toriel ask Sans to promise not to kill Frisk? She might have had time to go to the door and tell jokes after meeting Frisk and leaving them alone in the Ruins, but does the whole exchange that Sans talks about on your date happen between the dog stealing her phone as well? If so, she also says all this before knowing that Frisk intends to leave the Ruins, although she probably just assumed based on the actions of the other six humans.
    • It's been some time before the events of the game since she got Sans to promise. He notably doesn't talk about the other children that have been through as if he knew them personally, despite Toriel having met all of them and trying to keep them away.
    • Seems to me that this probably happened immediately before the battle with her. Note that Sans mentioned that she was usually happy and cheerful, but was more sad and somber when his conversation with her took place. Much the mood that she was in when the battle with her happened, since she knows you're likely going to be leaving her soon. Note that he's already there behind you as soon as you leave the ruins.
      • That seems to be stretching it. Narratively speaking, the player could literally be two seconds away from Toriel the entire time she's heading to the door. Sans also implied that he had been telling her a few jokes before she made him promise. Odds are that the promise occurred some time after the sixth human was killed but before Frisk showed up; possibly on an anniversary. Probably on the anniversary of Chara's arrival/death.
      • It could be that during the time she went to get groceries, what was "taking longer than expected" to paraphrase, she could have already been at the door to the ruins, talking to Sans; she had a feeling the cycle would repeat again.
    • I think that the most logical time for Toriel and Sans to have that conversation would have been when Frisk was asleep in their room, which is required to progress the game. While Toriel didn't want to let Frisk to leave, she probably already knew that such eventuality was still very likely, and took pre-emptive action.
    • Is it really required? I remember once going through Toriel's house without sleeping in the bed. But anyway, Toriel's dialogue to Sans isn't "A human is going to come through this door, please protect them," it's "If a human ever comes through this door..." Which implies more that she can guess it's going to happen again, but doesn't know for sure. It seems more likely to me that something — like an anniversary as said above — made her upset about the other deaths and she decided to take preemptive action via Sans.

     The death animation 

  • Whenever your HP falls to 0, you're shown an animation of your SOUL heart splitting in two and then shattering. Naturally, this is because a monster attack has killed you. But a pretty big plot point is made of the fact that Asgore needs your SOUL intact to destroy the barrier, so killing you only harms monsterkind in the long run. While this can be excused for some of the more malicious or idiotic monsters, the various Royal Guards, Undyne, Mettaton, and Asgore himself really should know better.
    • Maybe that animation isn't actually a death animation, but rather it represents resetting back to your last save.
      • This is likely the case. Your SOUL isn't shattering, but rather just returning to the Menu so you can Continue again through Determination. What supports this is that upon reaching New Home on a No Mercy run, Flowey will tell his story and how disillusioned he grew and how he attempt suicide — only to discover, after mortally wounding himself, he could use SAVE as well.
    • It's possible that you don't need the soul intact all the time. Even if it's shattered, the pieces are still visible as they break apart. Now, Asgore is keeping human SOULS in jars/power capsules/whatever you wanna call them, and even though everyone who owned them presumably died (suffering the same shattered heart animation), they're intact. It just may be that the souls can be reassembled/kept alive in these jars/power capsules/whatever. So basically, they're gonna try and kill you because it doesn't matter if your SOUL gets destroyed — they can put it back together and by the time it's repaired, it's trapped in a jar.
      • When fighting Asriel, your SOUL will re-fuse when it's destroyed. It may imply that even shattered, a SOUL isn't fully gone and retains some form of consciousness even if it's not whole.
  • Alternatively, the animation is merely symbolic of Frisk's physical death rather than their soul actually being destroyed. Either a human soul losing its HP simply results in the body dying, or the entire battle interface is a symbolic representation of Frisk themself dodging their enemy's attacks. (This is disregarding what Flowey says, as he is fourth-wall aware anyway.) ... Of course, that leads to some Fridge Horror if you instead take it to be Frisk's body shattering to pieces.
  • Or maybe Frisk shatters their SOUL on purpose to evade the And I Must Scream scenario that became the other SOUL's fates.
    • Or they have to shatter it to respawn.

     Protagonist's SOUL truly needed? 

  • So it's known that the barrier requires seven human SOULs to shatter, or a human and monster soul to walk through. Did Frisk really need to be killed for their soul, though? As Asriel shows when shattering the barrier, the SOULs don't get destroyed, but either go missing somewhere or return back to their host if they're still alive. Since Asgore already has six of the seven he requires, it should be possible to just absorb them and team up with Frisk's remaining soul (since humans can't absorb human SOULs) to shatter the barrier and things should be more or less fine. (This is of course not taking into account Flowey, as he was unexpected anyway.)
    • Not necessarily. Asriel's SOUL FUSED with Chara's when they combined; it's entirely possible he was only able to return any of them because he had no SOUL himself.
    • Asgore wasn't just in it for destroying the barrier, he was in it to keep the seven SOULs in himself so that he could become a god and wipe out humanity. Six is impressive but seven seems to be the threshold for power verging on omnipotence.
      • Are we sure we're talking about the same Asgore here? He's so much of a softie that he's actively trying to postpone the fight, makes small talk in attempting to offer Frisk tea, and even tries to make Frisk feel at ease of the situation. Even when fighting you, can tell he can't bear to look Frisk in the eye while he's fighting. In the end, he flat-out states he doesn't want power. He's not truly in it to have seven SOULs and become a god, he really just said it in a fit of anger and followed along thus far with the plan because it gave them hope. And really, the monsters just want the barrier to be broken, as they don't seem to have much malicious intent against humans aside from maybe Undyne, except for the player's actions, which can be straight up pacifist. It's not hard to imagine that the wiping out humanity part could be put to the side after this feat.
      • In relation to the above, see, that's the thing. Asgore had to keep up the deal he regretted because he was afraid of backing out. And he's been brooding about this for a long time now without really having any friends to talk him out of it. Toriel got disgusted and left and everyone else was so supportive of the idea because of the hope it gave them. Remember, you are the first human to make it to Asgore, everyone else was killed prior and had their SOUL transported to the castle. At that point Asgore doesn't want to kill you, but the alternative of confronting his hopeful subjects with changing his mind frightens him too much to heel-face. Only by Frisk's influence (after fighting them or after they brought everyone back from Asriel's godmode and broke the barrier) were they inspired to change for the better. Also, to the main point: Why would Chara willingly give up his life if human and monster souls could just be combined that easily with the human remaining intact? It's not like they were suicidal, that was clearly a gambit to get back up and murder people. Perhaps he simply can't just team up with Frisk.
      • How would 'teaming up' work? The only real way it could work like described would be if Frisk knew magic (like the 7 human mages who made the barrier), but considering Asgore's willing to commit suicide to let Frisk leave it sounds like there's no method of teaching Frisk human magic from within the barrier. Without that, there isn't really any way to get SOUL power from Frisk without actually taking their SOUL.
      • Imagine Flowey absorbing all the monster SOULs but instead it is Asgore absorbing Frisk. There's no need for Frisk to learn any form of magic, just let Asgore borrow their power to help in breaking the barrier.
      • The problem with that is there's no guarantee Frisk can survive that. Monsters have bodies that are largely made of magic so their being able to revive after the final battle might have been attributed to that. Humans have mundane physical bodies and it's quite possible that having Frisk's SOUL removed would kill the body and leave him with no where to to return to. There's also the question of if anyone other than Flowey even knows how to do that.
      • One of the entries in the True Lab states that removing the soul of a living monster would kill the soul's host. While this does bring a little bit of Fridge Logic to the final battle, odds are doing the same thing to a human would kill them too.
      • Would it remove their SOUL from their body though? It seemed kind of unclear but this troper interpreted it as the monsters being absorbed both body and SOUL. While you have a point with the fact that Frisk's body is more physical than it is magical, it seems doubtful that containing six SOULs (which is near omnipotent) wouldn't override this normal setback, or heck, even resetting/reversing the destruction of Frisk if it did after the fact. Death is shown to be a slap on the wrist when it comes to resetting.
      • Even with Monsters, Asgore's body is destroyed before his SOUL is revealed. Likewise, Asriel carried Chara's corpse after absorbing his SOUL. Likewise all the child souls are separate from their bodies in the coffins. Also even with all 7 souls, Asriel wasn't able to create a permanent body for himself. Determination is powerful, but it does have limits. It prevents you from dying, but it can't bring the dead back to life, which is what losing your SOUL completely would do.
      • Asgore and Boss Monsters in general are the only ones to have the SOUL persist for a moment after the body is destroyed. Any other monster would perish immediately if their body was destroyed, meaning it's impossible to absorb the SOUL of a monster without also absorbing the monster itself too. Determination ironically can bring the dead back to life, but only in respect to Frisk and the Monsters that you may have killed for the duration of the game. (By way of reset, which is part of it as Flowey/Asriel demonstrates.)
      • Alphys's notes mention that she already figured out how to extract SOULS from monsters, but doing so would kill the body too. Determination also isn't so much bringing them back to life as it is reversing time. At the very best, it can hold a SOUL together when it would normally shatter, but any further and you'd just be reloading to an earlier save before you died, which would be useless if you want to progress through a plan that involves dying since all you'd be able to do is go back to before you did it.
      • She notes a possibility of extracting SOULs via injection of determination to let it persist after death, but it doesn't work. The monsters instead melt because their bodies can't handle that concentration of determination. Besides, what Alphys was trying to achieve wouldn't be the same result for every other monster that Flowey absorbed, hence they must be absorbed alive; there was no other way. Asriel himself, while he doesn't go through with it, implies that resetting the entire world completely is just something that he can do now. Whether or not it reverts him back to his original state is unknown, but if it's any indication of the call you receive just before the second elevator brings you back to Asgore's place, then Asriel does have some power over time even before his transformation happens.
      • The note on extracting SOULs mentions it requiring a lot of power and "instantly destroying the host". Her notes on Determination come after along with finding out that it melts Monster bodies from the following experiments. The reason The Monsters come back in the end seems to be because Asriel absorbed everyone whole rather than ripping their souls out, which might not be possible with a physical human. Not sure what you mean by the elevator call but Flowey has always been able to reload to previous save files before Frisk appears. He notes it as just before he's about to die, he gets a strong desire to continue living, then he wakes up earlier in time.
      • The call comes when you bring the power back on in the True Lab and then walk through the second elevator. It's heavily implied to be Asriel since it's a voice you haven't recognised before and is just before Flowey's plans come to fruition. Flowey has indeed used that ability but Frisk's mere presence alone overpowers Flowey's determination. That's why once he gets the SOULs he regains that hold over the ability. Even if it's not possible for Asgore to absorb Frisk and not kill them in the process, Asriel's time travel showcase by calling you before the cause and effect happens could very well mean that Asgore can do something similar to Frisk's body/the barrier.
      • Asriel isn't time traveling, that's just Flowey using his original voice as Asriel so you don't recognize it. Flowey shows frequently he can alter his face and voice when he feels like it and is particularly fond of using a goat face to imitate either Toriel or 'your best friend'. To drive the point home, when you exit the elevator, it is sealed by vines, which is a Flowey thing.

     Saving Asriel 
  • So the one sad part of the True Pacifist ending is how, because he doesn't have a soul anymore, Asriel is doomed to turn back into Flowey. But after destroying the barrier, Asriel released all the souls he had absorbed and they returned to their original owners. Couldn't they have just given one of the six human souls, whose owners are no longer around to return them to, to Asriel so that he would not turn back into a soulless flower?
    • He couldn't control them even when he had all the power in the world. Who's to say that the soul would even let him? He tried to forcibly use them to destroy the world and kill another child. They didn't like that then, and there's no reason they'd like it now that he's been redeemed.
    • The Neutral and True Pacifist final bosses both establish that SOULs have their own consciousness and desires, at least to some extent. Even if they didn't, that'd be kind of a dick move, akin to desecrating the dead — since they do, it's arguably even worse. Asriel's probably had enough soul-hijacking for one lifetime.
      • Even putting the ethical question aside, let's remember that it took the SOUL of practically every monster currently alive in addition to the six human ones for Asriel to regain his original monster form. With only the six human SOULs...well, the Neutral ending shows us where that gets him.
      • The SOULs of nearly all the monsters basically equate to one human soul as explained during the Waterfall segment. So really it takes 7 Human SOULs or an equivalent thereof for Asriel to regain his form. This may be lying into WMG territory, but an idea that comes to mind is that Asriel's form is like plasma; it may take so much power to kickstart it, but once it's running then all that's needed to maintain it is a fraction of that. The fact that Asriel himself even boasts he's been only using a fraction of his full potential may support this.
    • Interestingly enough, there is a fan comic that plays around with this idea, except that it's Frisk's SOUL that Asriel gets, which was offered by Frisk willingly. While it's not canon to the plot, it does raise two questions; What if the SOUL was given willingly, and would it be enough to maintain Asriel's form?
  • On that note, might it be safe to assume that in the Golden Ending, Frisk told Toriel and Asgore about what happened to their son, so that they could find a solution? Alphys feels guilty enough about her experiments, but in theory the monsters can find Asriel or Flowey, contain him, and try to get him back to normal. It's the prince after all, and an eight year old monster that got coerced into assisting his adopted sibling in a Thanatos Gambit.
    • I can't see that happening. That would be the sort of information that could break Asgore, Toriel, AND Alphys. Learning that their adopted child committed suicide and was murderous, and was responsible for their biological son's death; and that said son has since been forced to live in a completely alien body, without a soul; driven to suicide attempts and potentially insanity, becoming amused by death and anguish, and that he would have to "exist" in that state forever... Can you imagine the parents being able to live with that knowledge, or Alphys (who is already suicidal) being able to get over her guilt for being responsible for dooming Asriel to that existence? The only person I can see Frisk telling is Sans, and that's only if they work out that he knows a lot more than he lets on.

    Royal Guard Sans 
  • Sans's attacks are leagues ahead of Asgore and Undyne, the most powerful warriors in the underground. So why is he not captain of the royal guards or at least among their number?
    • He promised Toriel that he wouldn't harm any humans, so that would be one mark against him for royal guard. Secondly, he's very lazy so it's doubtful he'd even bother trying for that. Also in terms of strength and strategy, Sans is stronger than Undyne and Asgore, but he isn't tougher than them. He only has 1 hp while Undyne takes several hits to beat and while Asgore can be cut down immediately, he at least has a lot more hp.
    • In addition, Sans can't dodge magic attacks with the kind of consistency he can dodge physical ones. The dude has 1 HP; one graze on a bullet board would take him down. Getting into fights with other monsters is something that is very much not in his best interest to do.
    • There's more to being a royal guard than just being strong. Sans doesn't even do his regular job of maintaining puzzles and keeping watch for human activity really. He's even converted one of his guard stands into a hotdog stand so he could slack off from work by doing completely different work. He's to the point where he doesn't even try to stop you as you tear your way through countless civilians, he ONLY directly fights you when you're not just a threat to Monsters, you're a threat to EVERYTHING. Undyne might not be as strong as him, but Monsters only speak about her with lots of respect and reverence. She begins trying to stop you as soon as she hears you're around, and she's so well known and respected that she can channel the hopes and dreams of all monsters in the No Mercy run. Royal Guards are like policemen, they have jobs and reputations. Sans is like a gorilla (no insult intended). He's on a completely different level strength wise than any other person, but he's not going to be chief of police like Undyne could be.
  • Because Sans would have refused, or just not did his duties?
  • Sans seems to be using his many 'jobs' as a cover for something else. The dialogue in the No Mercy run reveals he and at least one other person ('we') have been watching the timelines. By "slacking off" where presumably pretty much everyone in the Underground can see, nobody ever guesses he is something more than a layabout. It's the perfect cover. Being a guard would make him look too competent.
  • All in all, the reason he's not in the Royal Guard is that he's just too freaking lazy to do it, and thus, although he would be the strongest on the guard, he would also be the most useless, as he'd slack off 99% of the time.

    Sans's Behavior in a Neutral/No Mercy Run 
  • Sans knows there's a threat of you killing his brother. In a No Mercy run, he even explicitly states there will be consequences if you do. So why does he not stop you from killing his brother? For that matter, why does he wait until the end of a No Mercy run after you've killed so many people if he's already aware of the danger?
    • Probably because he promised Toriel not to harm you. Even then he only breaks it when he knows there's no choice left but to attempt to stop you/make you reset with his bullet hell, and at the very least he really doesn't want to see you again after killing his brother but staying Neutral otherwise.
    • Two other perspectives. One is he simply hoped you would change before it went too far. Even in his fight when you spare him, he hopes you don't come back/reset the game and bring his brother back. The second would be a gameplay reason. Imagine fighting Sans at the beginning of the game. Even at lvl 19, one level below the cap and dealing only one damage, he's still a tough fight. Taking him on at the beginning of the game would probably be an impossible task.
    • It's possible that Sans cannot hurt the player much when they are at LV 1 (He relies on KARMA to deal the heaviest damage). This is exemplified by the Genocide Route assuming you've played a nicer route first (i.e. skipping entire boss fights, forcing the player into green or blue mode with no tutorials.)
    • Not to mention Sans seems to pretty much expect everything to reset eventually, even if you do damage and kill people you'll just reset back to the beginning sooner or later and bring everyone back. The no mercy run is the only route that can never be fully undone.
      • It's possible Sans has TRIED to change things in previous timelines, but the most likely reality is current Sans wouldn't have that experience and so far as he is aware he has only lived one life — which makes me wonder if the "he doesn't act because he knows it's pointless" theory isn't entirely accurate, but that's another kettle of fishbones. He is aware of the time distortions, he knows they're repeating, but he isn't able to affect them (though fanon often suggests he can to heartbreaking effect, there's no hard evidence of this). He knows they've done this many times, and can hypothesise what you might do based on the evidence they have of those resets, but he doesn't actually remember doing this before and can't be 100% certain what the "best" thing is to do in any situation. Maybe if he acts, or doesn't act, Papyrus will be killed anyway. (Another thing to note is that Sans has 1 HP. He would be ridiculously easy to kill if he would only stand still, and he knows he's no good to anybody dead). I think it's best to think of each Reset worlds Sans as their own individual, entirely separate from their other timeline selves, and they act slightly differently each time.

    Nose nuzzle champs ' 98 
  • The dogi boast that they were #2 nose nuzzle champs '98. Later, you find the #1 trophy in Asgore's room. Toriel has been gone for so long that only old man Gerson can remotely remember her, indicating that the cup has been won a loooong time ago. This means that a)there were two nose nuzzle championships '98 (1998 and another one some centuries earlier, which begs the question of who got the newer #1 cup), b) the dogi are really just that old, or c) Toriel actually hasn't been gone for that long and people somehow forgot her in that short amount of time. None of these explanations really make sense.
    • If you look closely, the one who fell in the opening sequence is actually Chara. Chara fell at 201x. Toriel and Asgore are still together at 1998. It is unknown at what year the game exactly took place, but given the true pacifist ending, it is probably only decades later. It wasn't that long ago. Gerson is simply an old man who forgot things. People didn't pay attention to Toriel since she secluded herself in the ruins.
    • '98 isn't necessarily 1998. It could be any previous century.
    • For Toriel being forgotten, she actually isn't really, Alphys even mentions the day the queen left in her notes in the True Lab, presumably those close to the royal family don't say her name because it makes Asgore depressed, and you don't learn it until close to the end because it never became relevant until then. One decade, two tops is most likely, since it gives time for a new generation to come in (Undyne being trained by Asgore from youth and becoming the captain of the guard, the Bone Bros showing up) but not know the queen because those still aware of her don't mention it for Asgore's sake.
    • I would like to add that the lady taking care of the shop in Snowdin says the door to the Ruins has been locked "for generations". This implies that more than one generation has passed. Also, in reply to the above troper, Alphys also says "There's two of them?!" when being confronted with Toriel and Asgore, meaning that she likely knew of the queen's history, but not the queen herself. It's safe to assume that Dogamy and Dogaressa are not Boss Monsters since their souls disappear with their body instead of lingering, so perhaps monsters have drastically different lifespans depending on what kind they are?
    • It's also possible that the ruins had actually been locked from the inside for much longer than Toriel was there. Being the queen, she may just have had the key. If we assume the main character monsters mature similarly to humans, Bratty, Catty, and Alphys, who are roughly agemates, seem to be young adults. If Toriel left, say, 20 years ago, it seems pretty likely that monsters who grew up away from New Home never saw her. The Royal Guard, however... not so much.
      • Don't forget Undyne is also in that age range. She mentions she met Asgore as a child, and she's the only royal guard who we actually see fail to recognize Toriel. It's possible entirely that the dogs DID recognize her, but they weren't in that cutscene.
    • Since none of Gerson's stories about Toriel mention her children, it's possible that Toriel became more reclusive after Asriel's birth (basically being a stay-at-home mom), and that's why younger monsters don't recognize her by sight. They didn't forget her, they just hadn't met her in person before.
    • The timeline of Alphys' Determination experiments (she used the golden flower "that grew before all the others" — flowers don't live very long, and even if this one was preserved with magic, Alphys still knew exactly which flower was the first without having to ask Asgore — and most of the Amalgamates have living relatives, the youngest of whom is only a teenager) suggests that only a few years have passed since 201X, maybe a decade and a half at most.
    • Flowers don't live very long in our world. Food also perishes in our world. It's safe to say the laws of our world do not apply to the Underground.
    • It couldn't have been just a few decades because hardly any monsters recognize the player as a human. If it wasn't that long ago that a human was part of the royal family, lots more should know the kid's species immediately.
      • That is incorrect. True, some characters don't realize you're human, but most of them do. That's why they're trying to capture/kill you in the first place. The rest of them are probably having a Clark Kent moment where they're thinking "man, that little kid really looks like a human..." but find the idea that you're actually a human so implausible they don't even think twice.
      • No, no, no. Most monsters aren't trying to kill you on sight. It's stated at some point that they're highly resistant to magical damage and take advantage of this by using highly dangerous spells for mundane tasks. Note that almost none of the spells used by regular enemies seems like it was made for combat. They aren't fighting to kill, or fighting at all — they're goofing around, thinking that the player is another monster and thus also immune to magic. Or are we supposed to believe that Aaron sees a human, knows he can kill them and that he'll become a hero if he does, and is perfectly content with letting them go after a flexing contest?
      • I said "some", not all. Toriel specifically mentioned that the reason you'll be encountering monsters left and right is because you're human, and therefore, if a monster doesn't have an expressed reason for being near you (Temmie thinks you're cute, Aaron wants to flex with you for some reason, etc.), we can assume they're trying to capture you. And about how most of the attacks don't "seem" like they were made for combat, look at Greater Dog — he is definitely trying to catch you, and one of his attacks consists of a puppy frolicking around the screen. Just because an attack doesn't "look" like it's meant to hurt you doesn't mean it won't. It's a strange game, strange things happen. And as for why the monsters let you go after you do something nice to them, that's kind of the point of the entire game — monsters are naturally soft-hearted, and it's difficult for even an extremely hardened and strong one like Undyne to continually try to attack you even after you've shown her kindness.
    • The simpler explanation is that Asgore just didn't win the cup with Toriel, and nose-nuzzled someone else for the win.

     Toriel being mad at Asgore 
  • Toriel's reasons for being mad at Asgore seem somewhat hypocritical. She hates how vengeful he was for declaring war on humanity, but also hates him for not wanting to get his hands dirty by killing 6 humans. Question is: why didn't SHE take the first human soul, cross the barrier and kill 6 humans herself? She's the Queen of the Underground; even divorced from Asgore, she's still a powerful Boss Monster that's perfectly capable of breaking the barrier on her own to save her people. Did she not want to get her hands dirty? If so, then why insult Asgore for not doing the same thing?
    • It's not uncommon for the death of any child to utterly destroy a marriage in real life, much less the death of both your children at the same time. She was fed up with Asgore after the loss of both her children and searching for reasons to be angry with him, she just happened to also be right. She wouldn't have been satisfied either way.
    • When I got to that part, I interpreted it as wanting Asgore to kill 6 bad humans, the same way that Undyne says that she'll let you go, and wait for some mean human to fall so she can take their soul instead. I don't think anyone would've minded if Asgore had taken a human SOUL and used its power to hunt down 6 serial killers, for example.
  • Instead, she hides away in the ruins and TAKES CARE of the humans that fall down into the Underground. Why not kill them herself, if she wants to get out that badly?
  • I think her point was that she didn't want to leave if it meant killing others, and that she knew Asgore didn't want to do so either — because if he had, he would have done it the easy way that she mentions. He just didn't have the guts to tell his subjects that they were going to have to stay in the underground forever because the only alternative was killing seven humans, so he tried to do the killing in a way that made him feel less responsible for it. In the neutral endings in which Toriel takes over the leadership of the underground, she shows her actual viewpoint on the matter by immediately declaring an end to the killing of humans.
    • Basically, the choice was between "kill seven now and we go free immediately" or "kill seven slowly over a drawn out period while stringing everyone in the underground along on a promise of eventual escape (maybe-someday?)". If he was going to do something so horrible as serial murder, then he should've done it right away instead of letting everyone live in the dark (literally and metaphorically) for millennia. Toriel considered this cowardice on Asgore's part.
      • What she didn't realize, though, is that Asgore's plan had long ceased to be about destroying humanity the most efficient way. It was about keeping morale. While initially he declared war in an outburst of grief and rage, what made him stick to the plan was the nearly unanimous support of the monsters. Meanwhile, he had Alphys look into alternatives to break the barrier, the same Toriel does as a queen. It's telling that some violent Neutral endings have Toriel deposed for supporting the humans, or show the monsters hopeless as society falls apart.
      • Of course, Asgore's plan for 'keeping up morale' wouldn't have been necessary if he'd committed the seven murders that he claimed he would at the beginning (granted, that would possibly have led them right back into the same war with humans they had just ended, so maybe not the best plan straight away, but even so…)
  • But that's the thing: Toriel's idea would have (according to Asriel) started yet another war with humanity and led to genocide. Not to mention the fact that frankly she just seems to be lashing out. As Rhysellin points out here, "Toriel accuses Asgore of being simultaneously too meek and too violent. She says that he is a “miserable cretin” for trying to harm Frisk, but also a “meek coward” for not immediately slaughtering humans when he had the chance. It seems to me that her standards for acceptable behavior from Asgore are impossible to meet." Just seems like they both were in a no win scenario.
    • I honestly saw that scene as Toriel reacting to Asgore trying to justify his actions from the perspective of freeing monsterkind (and exterminating the human race) by saying "Oh cut the crap, Asgore, if you really wanted to end monsterkind's suffering, you could've done it by now! Don't dress up what you're doing as anything noble!"
      • Essentially, this isn't about him meeting her "standards" by doing or not doing what she would approve of. It looks like a no-win situation because it is one. Toriel's anger began the moment Asgore decided to kill a bunch of humans out of vengeance in the first place — how he intended to kill seven humans was irrelevant. It was just the lesser of two evils in her eyes to do it as quickly as possible to limit monsterkind's suffering.
      • ...or did it? There is much to suggest that her anger at Asgore began the moment Asriel was killed (a toxic grieving pattern which is often observed amongst couples whose child died unnaturally and sometimes even natural deaths is one partner blaming the other for the child's death as a coping mechanism). It's possible that on some level, the real root of her anger is an emotional need to punish someone for Asriel's death, and she seems to be focusing that emotional energy on Asgore.
      • What is this "much" you speak of? It seems far more likely to me that she's simply disgusted with Asgore issuing an edict of child murder and genocide out of rage and then being too in thrall to public opinion to correct his mistake. That's easily grounds to leave somebody in any universe.
      • A lot of her dialog seems to point to someone fixated on a pre-existing guilt complex and an obsession with children (even when it is questionable if the subject in question was, by any legal definition, a child). Furthermore, her speech to Asgore suggests that the war was merely one such reason, not the primary reason. Also, given that some of the endings have her doing much of what Asgore did as a 'solution' (hoping for a scientific solution but otherwise effectively sitting on her hands), one questions just what cheesed her off.
      • I can't deny the theory, but I think it's just as, if not more, plausible that Asgore routinely murdering every child that came through after is probably a more believable root for her anger than the death of a child in a manner neither of them could prevent — Toriel seems a fairly rational person at the end when she says "it's not fair to kill someone just to let someone leave" (or indeed when she realises at the start of the game that it's wrong to keep you there against your will), so while she might have a toxic grieving pattern going on, Asgore has done plenty more to actually gain her ire since.
      • That's the thing though… we only know for sure that one of the humans who died was a child (toy knife/faded ribbon), who may have actually fallen to their death given the positioning of the items. Toby has gone out of his way to refer to them as the HUMANS and judging by the items and their descriptions, most would be late teens or adults (especially the bearer of the gun and cowboy hat).
      • On top of that, several of the items are covered in monster dust and have really murdery sounding descriptions, suggesting that the users were killing monsters and had to be stopped. Furthermore, 'rationality' is often not at play when it comes to traumatic events. The forefront of this would be avoiding reliving that pain. In the above example, the parent will attempt to put blame on the other parent to cope. Given her judgement on humans, some of whom ended up being quite dangerous, I find the source of that ire questionable.
      • I don't see why the actions of the humans who fell should affect Toriel's anger towards their killer. She clearly doesn't believe in "an eye for an eye", given her efforts to protect the humans (whatever their ages, it's not really relevant), even is they actively try to harm her. This may be indicative of a guilt complex on her part, sure, but Toriel clearly didn't want anybody to be killed. So Asgore, again, routinely killing six people, could still anger her regardless of those person's intent. If all the humans since Chara had behaved like Chara — aka routinely slaughtering everyone — then Toriel's mercy towards them, and her being angry at their killer, would make less sense, sure… But we have no particularly solid evidence to suggest that the Fallen Humans were all violent and attacked monsters on sight, or even that those who did acted in anything but self-defense. Toriel perhaps doesn't see them as deadly creatures so much as confused and frightened (which they would be, and rightfully so — they just fell into a world of monsters from legend that their ancestors locked beneath the earth and then spent centuries spinning horror stories about). Toriel sympathises with them, and believes they were worth saving — Asgore destroyed their potential by killing them. (And yes, you can raise the point that some weapon descriptions "sound murdery", but do they really sound that bad? The ballet shoes, perhaps, and the tutu is implied to have monster remains on it. But the descriptions are mostly straightforward or interpretable —the gun, easily the most outwardly violent tool, is simply described as a gun without bullets and gives its stats.)
      • ...and trying to keep them locked up in her house also destroys their potential. Furthermore, her need to 'mother' even psychotic murderers also points to a guilt complex, perhaps even to the point of projecting their actions and tendencies onto Asgore. Also, bear in mind those descriptions, far from being straightforward, seem to hint at the nature of their former masters (the gun is empty, with one of said bullets possibly being the cause of Undyne's lost eye given hints in game, and the connected hat sounds as if it belonged to a worn and battle-hardened gunslinger). Far from fearful children, some of these descriptions point to some tough individuals far and away deadlier than Frisk. Leading me to doubt the 'panicked self defense claim'. You'll also note, I never said "ALL" humans. My point was is if even two or three of them were deadly genocidal maniacs, then it brings into question exactly where her anger comes from, and there is considerable evidence to suggest that.
      • What evidence, though? All I can think of are a few pieces of clothing that have darkish descriptions? Mentions of Dust on a tutu and dangerous ballet slippers (if that wasn't just a joke in the first place because what under earth is dangerous about ballet shoes — unless you count the risk to the muscle structure of the people wearing them?) We have barely any other evidence of what was going on in the underground during the time the other six humans were wandering about, but we just don't have the evidence to say they were genocidal or even murderous (re: the Undyne's eye theory. She says at one point in pacifist that she "used to think humans were cool [before meeting Frisk]", which I doubt she'd think if one of them were responsible for blinding her in one eye). The attitudes of those who figure out Frisk is a human (Papyrus, Monster Kid, Alphys, even Undyne, who is the most passionate about hunting you down, can't really think of much to say about how bad you are) don't seem to imply that any of the previous humans to fall were especially malicious or violent. Also Hypocritical =/= Having no right to be angry with someone for doing really bad stuff. Whatever Asgore's reasons — and I think he has as good a reason as it's possible to have — it was still murder and attempted murder, and whatever Toriel's guilt complexes or physiological issues or hypocrisies, her anger still seems perfectly well-founded. Both of them have flaws and hypocritical behaviour, doesn't mean either of them are entirely in the wrong.
  • The simple solution is that Toriel didn't want him to kill anyone. Human souls linger after death, and unlike monsters, they die of natural causes normally. It makes no sense for her to want her husband to just go around murdering random people because that's just not her character, but there's no reason that collecting six human souls from the surface means killing six people. Asgore could have walked through a graveyard and got the job done, but it's mentioned in a few places that Toriel is the brains of the outfit; it probably never occurred to him.
  • Toriel saw what humans were capable of during the war before the monsters were forced underground and sealed in. She just doesn't believe all humans, least of all children are evil by default or should be made to suffer or blamed for the actions of others, much less die. Her lingering anger at Asgore even after he shows remorse seems harsh but look at it from her viewpoint Even after the war they set up New Home, rebuilt their lives, she and Asgore were happily married, and had a child; it doesn't seem like life Underground was so terrible, and even if it wasn't ideal, they seemed content. One day, a human child falls into the underground and they wind up adopting said child and loving him or her as their own. They're all happy for a while, until both their children die on the same day; unknown to her or Asgore, one is a case of suicide (they think it was just illness), while the other was more obviously murdered. Asgore in a rage declares war on all humans and orders that any future human children that fall into the Underground are to be killed, ignoring the fact that their own adopted child fell from the surface and was human, Toriel, grieving and reeling the loss herself, still tries to dissuade him and drag him out of his vengeful mindset, and when he refuses, Toriel, unable to bring herself to go along with such a plan, leaves him in disgust. Possibly she was also disheartened by how fast the other monsters would cheer on such a plan too, considering Chara, whether evil or not, did seem to be well-liked among the monsters in general, while he or she was alive, and she had loved them as her own child. So she goes to the Ruins, sets up a home, and locks herself in.
    • The first couple of children she maybe just cares for and allows to rest and recover from the fall, maybe explains a bit about the world, but lets them go when they ask, but then they die. Saddened but determined after their deaths, she sets up puzzles, training dummies, and tries to more actively teach and train all future children to fall how to survive, but still they die. In the meantime, she is developing her friendship with Sans, one day after a child has died she is really upset and Sans notices she's not really responding to his jokes and asks her what's wrong. She asks him to promise to not kill any humans who go through the door, and he agrees. The children do get further, but still die. Toriel cannot take losing yet another child, which is why she decides when Frisk falls, the only way to save them is to keep them with her and block off the exit to the ruins forever, even if that would mean isolating herself even further too. It's not that she wants to force you to stay, it's a last resort, because to her, why would she trust that Frisk stood any chance of surviving at all when none of the other children did?
    • She probably knew all of the previous fallen children personally and likely grew to care for each to some degree, plus consider her compassionate and nurturing nature, and the fact that Asgore's law, whatever his reasons or regret, effectively caused her to relive the deaths of her own children over and over again… I think she has every reason to feel deeply hurt and angry. And forgiveness for something like that would take time, not be the instant result of an apology, even then expecting the relationship to ever go back to the way it was before the damage was done isn't realistic or fair to expect; sometimes what we break can never be fully repaired.
    • Toriel was right and her plan could have been carried out non-violently. Asgore didn't need to kill six or potentially seven times to break the barrier, or need to kill at all, humans have shorter lifespans than monsters anyway, they could use the soul of a person who died naturally to get to the surface — obtain the souls of people who are about to die anyway, and then use those to break the barrier, after which all the souls are released, and the monsters freed. Murder and violence was never necessary. Toriel would have acted to free the monsters herself if given the chance to do so peacefully, but was not willing to do so by force or at the cost of innocent lives.

     The Timeline 
  • During true pacifist, Catty and Bratty mentioned the monsters had been in kept in the underground for a millenia. Let's assume it wasn't an exaggeration (since the humans during the war looked medieval). In the true pacifist ending, it is revealed the human that fall in the beginning is Chara, not Frisk. So Chara fell in 201x (supported by the old calendar in Toriel's house).
    • How is it that Chara the first human that fall in about thousand years (more or less) into the underground? Is there really no other human that ever climbed that mountain (and fall) within a thousand years? And the first human that managed to do so, is a child?
      • Since the mountain was where the monsters were sealed away, it stands to reason that humans would stay away from it lest they accidentally fall down a hole there or release them. Over time, the whole war against monsters and humans and the mountain's story becomes folklore, and while they might not know what exactly happened, they do know it's bad to try climbing it. Chara, who's a young child and probably doesn't know about it or does but doesn't care, ends up in a situation that makes them hate humanity. Maybe they got into a scuffle with the village or he has terrible luck, but either way it pushes him to run away where no one can find him; the mountain. There he trips, falls into a hole, and lands in the Undergound.
  • Toriel and Asgore kept a VHS recording before Asriel's birth. Assuming Asriel grew up at the same pace as humans, he was more or less Chara's age, so he was either born in 199x or 200x. Gerson implied Asgore was there during the war.
    • Just how old are Asgore and Toriel? Did they wait for about a thousand years to finally get together and conceive a child?
      • It's entirely possible. The lore notes that Boss Monsters like them don't age unless they have a living child, so they could be thousands of years old.
      • See Immortal Procreation Clause, even if they were together when monsters were first sealed up (it's never stated, but commonly accepted fanon they met/married before the war), it's possible it just took them a thousand years of trying to have a kid.
      • Boss monsters are effectively immortal until they have a child, then once they do have one they die relatively soon, probably not long after the child reaches adulthood. With this in mind, I think it's quite plausible that they really have waited all this time, until they decided that they have lived long enough and are ready to grow old and die.
  • Monsters started collecting human souls after Chara and Asriel's death. It can't be more than decades (in the true pacifist ending, the surface doesn't look that 'futuristic'). And suddenly there were six more humans fallen into underground, after a thousand years without humans. And all of them were children, given the coffin sizes.
    • How is it happening? You'd think there were adults or teenagers climbing the mountain. Did the mountain suddenly become a popular choice for suicidal kids? Is there some kind of magic that ensure only children would survive the fall?
      • Since we know that at the time of Chara's death and Asriel's emergance from the underground, there was a village nearby which was most likely rural. This cuts down most potential visits to the mountain to the village only. The village probably considers the mountain a bad omen that they stay away from or consider it dangerous. This means that children who aren't as privy to this information and in the case of Chara, didn't like humans, played around there or even ran away. Over time it becomes condemned as a place where people/children disappear if they scale the mountain and nobody wishes to go near it, especially after the incident with Asriel and the humans possibly fueling this fear.
      • There's also the simple possibility that the hole that the kids started falling down simply wasn't there, there might have been a cave-in at some point that led to the underground and Chara was the first one to find it.
      • Do they ever actually specify that all of the souls that they got were indeed from children? Because I find it fairly hard to believe that a child falling into the Underground would have a gun, even if it is an empty one.
      • The coffins are all the same size as Chara's who we know to be a kid, and the children's shoes in different sizes at Toriel's home may be another indication. It could also very well be a nerf gun or a plastic toy gun.
      • The coffins may all be the same size, but they're definitely taller than Frisk. Maybe Chara was placed in an adult-sized coffin, since who keeps a bunch of child-sized coffins around?
      • Monsters turn to dust when they die, and the library entries indicate that they don't use coffins. (Or urns, for that matter.) The idea of coffins has to have come from somewhere else.

     Royal Guard recruitment policy 

  • In one of the phone calls, Papyrus brings up a good point: how did the Lesser Dog get to be a royal guard while he didn't? The whole reason Papyrus couldn't join was that he was too sweet and optimistic and could never really hurt another person, but the Lesser Dog is at the very least as bad — he's only looking to be pet and it's incredibly easy to make him stop fighting altogether. What was the rationale for Undyne to let him in, while still snubbing Papyrus?
    • To an extent, you can say the same about Greater Dog since he only fights because he thinks it's play and it's very easy to get him on the player's side since he's just looking for affection.
    • You can die against the dogs, you can't die against Papyrus. Even Toriel, who didn't want to kill you, could kill you. He's that pacifistic. To put it simply: Lesser Dog will kick your tail. Papyrus won't.
      • Pretty much. Dogs are apex predators and, while friendly and sweet, they are perfectly capable of guiltlessly taking a life if they have to.
    • I think the whole point in Undyne only wanting to let Papyrus join the royal guard after he captured a human is that she knows that he's too nice to do so (seeing as she said that Papyrus would be too nice to do well as a Royal guard), or that she doubted that another human would drop down into the underground because she can't get herself to let him down and to give him hope.
      • Undyne also cares very strongly for Papyrus and may be too afraid of him dying in the line of duty due to his foolhardy niceness. Nice and distractable as Lesser Dog and Greater Dog may be, they're still not stupid enough to try to spare an unrepentant murderer.
  • Undyne specifically mentions Papyrus' niceness in the context of being killed – that he would let himself get cut down with a smile. Lesser Dog may not be the most efficient, but he certainly isn't pulling his punches just to let you go free.

     The gun 
  • Is it a real gun? How did one of the children manage to get a gun?
    • It's more or less stated that it's a real gun, just out of ammo (the cursor having to be accurate is most likely just a meta-nod to make it stick out, and not actually shooting), given the whole "nobody climbs Ebott for happy reasons", it's easy to assume they stole it before running away from home, or they were given it by their parents who were sentimental enough to at least give them a chance, but still chose to abandon them.
    • Also, no one ever said that any of the other humans was children, let alone that all of them were. It's just what bloody everyone here assumes for some reason. Maybe this one was actually carried by an adult? It may even have had bullets once, but they ran out.
      • It's assumed that they were all children because the coffins of the humans are shown to be the same size as Chara's coffin, who was also a child. There's also that box of children's shoes that Toriel has in her house.
      • The coffins are definitely taller than Frisk — it's probable that Chara was placed in an adult-sized coffin, since nobody keeps a bunch of child-sized coffins around. That box of children's shoes might also belong to Asriel or Chara, since fallen children wouldn't randomly leave their shoes with Toriel in preparation for walking all over the Underground.
      • To be honest, the coffin size doesn't tell us anything. The Underground wouldn't have Coffins at ''all' is the thing here — we learn of Monster Funerals from the library, and the bodies don't stick around. The coffins downstairs were likely just Asgore's attempt to be at least a little respectful of those he'd slain by placing their bodies in what he remembers to be a traditional human burial casket. With that in mind, it's no wonder that all the coffins are the same size — he might've planned ahead, and Monsters just wouldn't be particularly familiar with making coffins anyway. So there's no certainty that the coffins size is indicative of the age of the owners.
      • That box of shoes comes in "a disparity of sizes", so they couldn't just be Asriel/Chara's shoes alone.
      • Kids' feet grow. That's totally what you get from having two little kids growing up, plus whatever of the other kids wandered through.
      • Hoping you realise "disparity" means great differences, not minor like a child's feet growing would do. But yeah, it'd be most likely that the disparity comes from the other 7 humans.
      • A child's size 12/1 (UK sizing) and a child's size 4 would probably be a bit enough difference to constitute as a disparity, so there's no certainty that using the word disparity means any of the shoe sizes were bigger than a 5. Incidentally, I was a size 6 by the time I was 11 and I'm only 5ft 2"; kids can have big feet.
      • Even if they are a child, in lots of parts of the world it is more or less normalized for kids to grow up around guns and learn to use them.
    • Bit of WMG here, but it's possible it was actually a toy gun and neither the monsters nor Frisk have seen a real one before, so Bratty and Catty just assumed it was a real gun and Frisk just took their word for it (or made the assumption themselves in a Genocide run).

     Neutral-Pacifist Ending 
  • In the Neutral Endings, Frisk exits the Underground, leaving the monsters behind. But at least a human soul and a monster soul are required to pass through the barrier. So in the Neutral-Pacifist ending, in which you do not kill anyone but only don't date Papyrus, Undyne, and/or Alphys, whose monster soul did Frisk use to get out? Asgore's soul was destroyed by Flowey and Flowey himself has been explicitly stated not to have a soul.
    • The battle with Omega Flowey involved major distortions to the world and far more power than just one human and monster soul. The aftermath seems to place Frisk somewhere outside of the barrier just due to how chaotic it was. In repeats, Flowey still takes the 6 souls and probably throws you out of the barrier just to get you out of his hair.
    • It doesn't take a human soul AND a monster soul to pass the barrier. Just a human soul. The barrier was made to keep monsters in. It seems that that's the full extent of its power.
    • It does take a human soul and monster soul to pass the barrier according to Alphys, but presumably on the inside as Frisk falls into the Underground at the start. Toriel confirms this in the True Pacifist ending.
    • One semi-plausible theory by some that subscribe to the Narrator Chara theory is that Frisk absorbed what was left of Chara's/Asriel's soul when they fell onto the same flower bed they died on, which gave them enough power to cross the barrier without having to absorb another monster soul. Before you argue "But humans can't absorb human souls!": Chara and Asriel died as an ascended monster with a fused soul, and if the Genocide ending is any indication, Chara might not be entirely human to begin with. Not the most watertight theory, admittedly, but it's something.
    • My theory is that the seven human souls together could put a temporary dent in the barrier, but without a monster soul, it wasn't powerful enough to make it permanent (In the pacifist ending Asriel needs the monsters' souls to destroy it).

     Chara, destroyer of worlds? 
  • How does Chara plan to kill everything, exactly? In the monster world, they most certainly could, seeing as how they have that much hatred. But hatred doesn't amount to anything in the human world, so does that just make them a child running around with a knife? I know it's implied Chara's pretty much a demon or a malevolent being at this point, but we don't actually see any of those powers other than possessing Frisk.
    • Chara's speech implies that he's that feeling when you level up in an RPG game. If we take that at face value, then what he is simply stating is wrapping things up and moving on to the different game. After all, when you've finished an RPG you would usually move onto another one. Chara destroying the world is symbolic of "There's nothing more to be done in this world, move along." Since Toby Fox suggested naming the Fallen Human on the naming screen after yourself, the implication is that Chara is in you, the Player, and you're taking the spirit of "kill everything" to other RPG games.
    • Another thing that it can be taken to mean is that Chara directly attacks you, because since you're the player, the world stops existing when you die, so in killing you, he's taking the world with it. This fits in very well with how the fourth wall shatters like glass in the final moments of the No Mercy run.
    • I just thought he took the six souls Asgore had, and became an all powerful being, literally destroying the world.
      • Humans can't absorb human SOULs and the same for monsters with monster SOULs. Chara has to manifest himself through Frisk's body so it wouldn't apply, but perhaps he can do it simply because he doesn't have a SOUL in the first place? He most certainly has one when you make the deal, however.
      • Chara is no longer human, they're a soulless creature like Flowey, who was able to absorb monster souls in spite of being a former monster.
    • Chara could kill Asgore or Toriel and absorb their Boss Monster souls. The engravings in the waterfall area say that doing so gives a human godlike power, just like a monster who absorbs seven human souls. With that power, they could then annihilate the human world. (In practice, the monsters could fight back by each absorbing the souls of seven willing humans, but the resulting warfare between demigods would probably cause catastrophic disasters either way, and it's possible Chara with Asgore's soul would have enough power to annihilate everything before any monster realized what needed to be done to stop them.)
      • No they don't; they say that a monster absorbing a human soul becomes incredibly powerful and that seven human souls are needed to break the barrier, but it doesn't say anything about a human becoming godlike by absorbing a monster soul. That wouldn't make any sense anyway; we know seven human souls=godlike power, so if a human soul+a monster soul=godlike power, then a monster soul would have to be equal in power to six human souls, whereas the engravings say that it takes almost every monster soul in the Underground to equal one human soul. The only thing we know absorbing a monster soul does to a human is that it allows the human to exit the Underground through the barrier, and even that's debatable (since it's implied Frisk was able to escape without one at the end of a Neutral run, and two of the main characters — Papyrus and Undyne — seem to think you'll be able to get through without it as long as Asgore lets you pass).

     Sans' Photographs 
  • In the [lab that Sans lets you into if you reload multiple times at the final corridor, checking the leftmost drawer brings up the description "There are photos of Sans with a lot of people you don't recognize. He looks happy". That's still an unsolved mystery for Sans' backstory, and all in all is interesting but not too crucial to the plot. However, when you come back after fighting the True Pacifist Boss Battle, the description changes to "There's a photo album inside the drawer. There are photos of Sans with a lot of people you don't recognize. ... and, one photo of you standing with Sans and all your friends". This is in most likelihood referring to this photo, which you only get after deciding not to stay with Toriel and after finishing the entire credits sequence. This would make sense if somehow Sans managed to keep the photo after a potential reset or load to the last save, but the photo still appears in the drawer even if the player/game has not gone through any sort of reloading after getting the True Pacifist Ending for the first time. Does that mean Sans can access different timelines of different games/playthroughs, even if they're not on the same plane of existence (read: different computers)?
    • Occam's Razor: the photo is taken after you defeat the Final Boss but before you leave the Underground (hence why everyone is together). Sans then placed the photograph into his album and returned to the rest of the group using his pre-established teleportation powers. Just because you first see the photograph after the end credits does not mean the photo was taken after the end credits.

  • If the damage you do (and your LV) is related to how much you wish to cause harm, then why is killing Jerry so hard? No one likes him, you'll ditch him without even thinking twice, shouldn't the damage caused by an attack be even bigger on him than on the other monsters in the same fight?
    • Jerry's obnoxiousness trumps bloodlust.
    • Jerry is less empathetic than other monsters, so your killing intent doesn't affect him as much.
    • Jerry is so repulsive that not even Chara would want to tolerate him long enough to kill him.
    • Perhaps Jerry is just so obnoxious, that Chara feels that killing him would be doing the other monsters a favor, and Chara wants them to suffer?
    • It is likely that at this point in the game, you will be using the Tough Glove. This means that you have to punch monsters to kill them. Punching Jerry would require touching him, and this disgusts Chara so much that they are unwilling to kill him.

    Humans use magic 
  • It's been stated in the game that humans will never know the joy of using magic, but their souls have other qualities. When humans can't use magic, how did they erect a MAGICAL barrier? Seems like a large plothole.
    • It's a rather good question, one thing that it can be meant is that in the time that passed since the barrier's erection and the events of the game, The Magic Goes Away and humans, while once able to use magic, couldn't when the book that explains this was wrote. Also, the barrier explicitly states it's SOUL power and not magic, which, given the difference between Human and Monster SOULs and what they're capable of, it's possible that it's distinct from magic in an entirely different way, and that's why monsters specifically need human SOULs to break it.
    • Something to point out: the lore says that humans will never know the joy of expressing themselves through magic. Not that they can't use it. Monsters are made of magic; they often use it in ways that's personalized for them or expresses their feelings (like making bullet-pattern birthday cards). It's possible that humans have to teach themselves magic, and can only use it in limited ways (i.e. "spells").
      • Building off of this, look at how we see Monsters utilize magic. They shape and mold it for all sorts of things. Napstablook uses it to create hats and words, Toriel uses her fire for things like baking delicious pies and creating a completely safe fire for heat and light. To them, magic is a part of them, something that they can shape and use freely. To humans, magic is likely something that they can't really control easily (they can tap into fire, but they don't have a way to control it to bake a pie, only to light an ACTUAL fire). They can use it, but not with the same freedom (otherwise, it's likely that they could have removed the barrier)
    • Yeah, monsters are made of magic, so using it is as natural as moving a limb is for a human. Humans, on the other hand, can learn to use spells that, with their much heartier bodies and stronger souls, have the potential to surpass anything a monster could do, but it takes a lot of study and effort.

    Monster Attacks and Your Soul 
  • In gameplay, your SOUL is locked in a box. Monsters use a variety of bullet patterns to try and hit it. Some of them don't know you're human, and some think they're actually helping you. But many others fight you to take your SOUL. So why would the monsters try to destroy what they're trying to capture? Is the gameplay not as literal as "this is your SOUL, avoid such and such?" Are they just trying to weaken your SOUL so it'll be easier to capture?
    • The library has books writing about monsters expressing themselves through magic. Given that they are magic, it's likely that some of what they do wouldn't necessarily be an attack against another monster, rather just an over-enthusiastic greeting or something that hurts all the same against a body made of meat. It's impossible to say where the line between "bullet pattern birthday card" and "just plain bullets" is since they don't seem to know how humans work. The gameplay is so abstract that it's hard to say just what happens in any given battle.

    Mettaton's second form 
  • Is Mettaton NEO incapable of attacking you at all? If so, why didn't he stick with the box form? The lack of attacking clearly can't be because he doesn't want to hurt you, because he can kill you on the pacifist/neutral run.
    • If you haven't killed everyone yet, and go to fight him, he makes a big deal about how you "won't harm humanity" once you cast the first stone. He was most likely waiting for you to make the first move to judge what you would do. He also mentions how Alphys should've worked on the defenses more once you strike him down: he wasn't expecting to be taken out in one hit. Theoretically, the most likely course of action he was planning was to tank the hit and then judge based on that whether you were a threat to the world or not.
      • Mettaton's box form still has a huge switch on the back, so it's not ideal. He's also capable of ending your No Mercy run just based on what you do. He's a showman, the only person you fight that actually could tank a hit was Undyne, so coming after that, he instead tries to appear so flashy that you stop your momentum just to see what he can do, which would cause you to lose because he succeeded in getting you to do something other than senselessly slaughter.
      • If by "based on what you do", you mean the rumor that you'll go off the Genocide path if you do anything other than immediately attack him, that's actually false; You can faff about for 20 turns and whiff your attack as much as you want, but you'll only go on the neutral route if you didn't kill everything beforehand. The misconception most likely comes from the line where he mentions "you were holding back".
      • This bothered me too for a while, since the Pacifist run makes a big deal out of Mettaton being immune to soul-based attacks, with a perfectly logical explanation. But in a No Mercy run, you have the Glad Dummy to show that Frisk/Chara's soul has become strong enough to easily kill a ghost possessing an object. It can be inferred that Mettaton had no chance of surviving a hit, and took a more intimidating form on the slim chance Frisk/Chara didn't know that.
      • Only problem with this is the nature of the Mad Dummy's corporealization is different from Mettaton's. The Mad Dummy bonds with the entire dummy body, whereas Mettaton is only fused to a core component inside of him from which he controls the rest of the body. This is why Mettaton needs power to move, whereas the Mad Dummy was perfectly capable of moving an an otherwise inanimate object even after fusing with it. The only reason Mettaton EX (and presumably Neo) was vulnerable is either because his body is unfinished and fragile, and/or his SOUL core is not properly protected. (On his EX Body it's outright exposed.) In this way, Mettaton in his box form should be immune to the player's LOVE for the same reason as a human. Like a human, he is essentially a SOUL protected by a body made up of purely physical matter. This would have actually made him an effective human-killing machine if Alphys had actually put more time into that function. Being made of metal and sturdily built gives him the fringe benefit of also being resistant to actual weaponry. Really, even with the switch on his back, he still stood a better chance in this form than he did as Mettaton NEO. He should have at least considered the fact that the NEO body was unfinished and might be more dangerous to use in either case. It's quite possible though he was ignorant to how LOVE functioned and thought he was just as vulnerable as any other monster, so he went NEO to at least try to intimidate/stall you.
      • Maybe Mettaton accepted the bad defenses/higher attack tradeoff of the NEO body because he wasn't corporeally bonded to it before confronting you, so he didn't expect your physical attacks to actually work. But he bonded with it by accident or something.
      • Perhaps, he's just trying to live out his dreams of being a star. He knew that, even if he took the box form, you'd eventually find some way to destroy him. So, instead of just letting himself be worn down to buy time that isn't needed, he decided to go out with a flash. To not go out as some naive, dull grindfest; but to die as himself. ...Feel free to drop that off [[Tear Jerker/Undertale here]].

    Asgore and the Barrier 
  • If Asgore didn't really want to hurt the player character, why didn't he just absorb the 7 human souls and ask the player character to attack the barrier with him? Wouldn't that be the power of 8 human souls attacking the barrier at once? Or why didn't he just keep the children in New Home until he had 8?
    • Asgore didn't have seven human souls. He only had six, which were all sealed in jars. The soul of the first child was absorbed by someone else, and probably disappeared when they died. It takes seven souls to break the barrier. Still, the game heavily implies that the souls' power needs to be concentrated in one place (Asgore) in order to break the barrier from inside. It can be argued that the humans who originally made the barrier didn't need to do this, but they still made the barrier by casting a spell. Monsters' magic is very different from human magic; they don't use spells, much less know any.
      • Maybe not quite related, but what happened to the first human's soul is that Asriel absorbed it. I imagine that since it was then bonded to Asriel's soul, when Asriel died and his soul died, Chara's soul died with it. It never was stated what happens to a human soul after it is absorbed after all, it may just be converted into power for the monster's soul.
  • Why didn't Asgore attempt to absorb six human souls, and then gather up the monster populace and borrow their souls long enough to break the barrier, like Asriel eventually did? It is inscribed in one of the runes in the Waterfall that every monster's soul could equal one human soul, so he could have broken the barrier long before Frisk showed up. Did he feel he needed the seventh soul to retain his godlike power in the eventual war against humanity? Was it Asgore's cold feet that had him draw out the plan as long as possible? Were there some monsters who did not trust the king to possess their soul?
    • "A monster cannot absorb the souls of other monsters." Remember, Asriel lost his own SOUL. He was meant to be an empty vessel.

    Mettatton's Origin 

  • It's said that Mettaton was either reprogrammed to be a human-hunting robot (by Alphys on a Neutral or Pacifist run) or created as one (by Mettaton himself on a No Mercy run), but if this is true, wouldn't Mettaton have a problem with it? When using Bratty and Catty's Mystery Key to access his old home, you learn that he created, or at least regularly attended, a human fan club — not to mention that his dream was to become humanity's star. Did Mettaton plan to run off with the first human soul he confiscated? Was this before his ghost self possessed the original robot? Was it a sort of repayment for Alphys creating his perfect body? Also, how long have the ghosts been around? Mettaton seems to know humans better than anyone but the Dreemurrs, considering having a fan club while still passing Alphys's "Human History" off as dumb cartoons. (See Mettaton's Diary Entries)
    • Mettaton says himself that the whole "reprogrammed to hunt humans" thing was a lie Alphys made up so that she could play hero. He was just playing along until he decided to kill you so that he could save the rest of humanity.
      • So, the reprogramming was a lie, but he does still tell you that he was built to kill humans during No Mercy... They just decided that the killer robot was fit to be a TV star in his spare time, I guess.
      • It could also be that going along with Alphys failing to create an artificial SOUL, she had the killer robot body already created but couldn't figure out how to get it running and later met Mettaton and let him use it instead.
      • Mettaton shows up in Snowdin manning the anti-human defense puzzle, although he isn't recognized. He also says in the quiz show that he was built to impress Asgore, since the king is interested in weaponry. Those varying backstories were probably just something Alphys cooked up and he went along with, since it's not a bad backstory at all.
    • I saw a theory hypothesizing that both the neutral and no mercy backstories were lies, and the truth is that Mettaton always started as the box and Alphys altered the nearly-finished EX model to NEO in a no mercy run. I think this makes sense — after all, why would his original form be called "NEO"?
    • We can almost definitely conclude that Alphys was lying in the neutral run (the whole thing was just a setup to make Mettaton seem like a villain so she could save you; he was never actually a human-killing robot at all in that path). The No Mercy backstory is harder to be sure about, but my theory is that he was simply bluffing to buy time for people to evacuate — after all, he dies in one hit and never attacks. He knew you wouldn't know his backstory, so he invents something intimidating-sounding on the spot in hopes that it'll make you delay a few more precious moments before killing him and buy everyone else a bit more time.
      • Yeah, considering the No Mercy path is the only time that even comes up, this theory seems pretty likely.

    The Genocide Evacuation 
  • So wait, if you go on a Genocide, the Underground evacuates, right? So... where, exactly, are they evacuating TO? Hotland 2 or the other parts? The True Lab? The Capital? These are the only places you NEVER visit in the Genocide routenote  but I can see only one making sense...
    • If you abort it into a 'normal' run at the very last opportunity, your phone call from Alphys implies she took everyone to the True Lab after you fought Undyne.

    Papyrus' Bones 
  • Where did Papyrus get the bones he uses to attack you? He has a box at his house where he keeps the ones he uses on you, so they were actual physical bones rather than just a metaphor for "being attacked by a skeleton". Monsters turn to dust when they die, there'd be no bones to gather anyway that way (plus, given his strange theory on why Humans have skeletons inside them, it's likely that even if monsters contain bones at all, he isn't aware of it). He doesn't seem to be using his own; he's never drawn missing any, his attacks seem to use far more bones than he's made of, and frankly if he was attacking by hurling his limbs around, you'd expect some jokes about it. No-one else except Sans is shown making use of bones, in or out of combat, and given how much time has passed it seems unlikely that any bones that may have already been there were still around to be gathered and intact enough to weaponise, but Papyrus uses *hundreds*.
    • Most likely he creates them from thin air with his magic, and then just gathers the created bones in a box afterwards, so they won't be left lying around.
    • Maybe he kept them in the box if he wasn't fighting and summoned them during the battle?
    • Being monsters, there's a chance Papyrus and Sans are only skeletons in appearance; that their attacks and bodies are comprised of other organic material, and that everyone, including themselves, calls them skeletal because of their appearance. When you actually land a hit on Sans, he bleeds in an unbroken line, as if there were no space between his "ribs", and that's assuming the blood spilled from real bones can splatter the way they're shown. After all, Tsunderplane is shown blushing once you can spare her, and despite being combustible(?)... planes don't have blood, and you kinda need that stuff to blush, implying that monsters may not necessarily be made of the same substances they're modeled after. Maybe.
    • They probably just washed up at the garbage dump like every other human artifact.
    • The same place Undyne gets her spears from. No one said these were organic bones.

    Muffet Battle 
  • Who paid Muffet to attack Frisk? She explicitly states that 'someone' lied to her about Frisk being violent towards spiders and offering her money for Frisk's soul, but as far as I'm aware, the game never elaborates on exactly who it is. The only two candidates that spring to mind have serious problems: Flowey is relying on you to reach Asgore to complete his plans, so it doesn't seem to make much sense for him to set a potentially fatal trap (and besides, you'd think Muffet might comment on having been spoken to by a flower), and Mettaton is at that point still only pretending to kill you as part of Alphys' plan (explicitly sparing you from the coloured tile puzzle which comes afterwards), so leaving you in a situation where you can't be rescued seems strange. So who tricked Muffet?
    • It's heavily implied it was Mettaton trying to be sneaky about it; sure, he's still honoring the puzzles for Alphys' sake, but if you suffered an awful misfortune outside of his scenes, then he gets his wish and also gets to wash his hands of letting Alphys down/betraying her trust in him.
    • Mettaton outright admits that he's the one who hired everyone to kill you, meaning both Muffet and the assassins in the CORE before you fight him for real. He approached Muffet in his EX form so he wouldn't be recognized (which would risk revealing to Alphys that he was going off-script), which likely means that he did the same for the others. Muffet even says that she caught a glimpse of her employer starting to change shape after their deal, but didn't see it clearly enough to realize what was actually happening.

    Who exactly knows... 
  • ...That the protagonist has the power of time-warping determination? From what I can tell, only Sans and Flowey are supposed to know, but a lot of characters judge you morally as if they know you can do that too, like with Undyne and what's implied to be most of the monster population if you get a "killed too many monsters but left all the important characters alive" neutral ending, who hold you to the same "if you can infinitely rewind time, you have no excuse but to go for perfection" moral standard that Sans and the game hold you to. Do they actually know?
    • They don't. Only Flowey and Sans (apparently subconsciously) are aware of SAVE and LOAD. The others can still take issue with your actions in a single timeline. In your scenario, from their perspective, you may not have killed the important characters, but you still killed a significant number of people seemingly at random. To you, the player, it's just a few mistakes, but to them, it seems to be cold-blooded murder. They have a right to be angry about that even if they didn't know that you have the ability to undo it all at will.
      • Exactly. They don't consider "not killing people" to be 'perfection,' they consider it 'normal monster behavior.'
    • Except nearly every single one of the monsters you are likely to kill was trying to kill you first, so calling it cold-blooded murder is absurd without knowing that the monster who did the kills was so impossible to kill that any threats to their well-being are irrelevant.
    • Actually, most of the monsters aren't trying to kill you at all. They use those bullet patterns for things in their daily lives like birthday cards and probably other things too. While there is a book about it in Snowdin's Library, it's likely that nearly no monsters know that humans don't respond well with bullet patterns, and those who do know are trying to attack/kill you or at least know because they are/were in ranks with said human hunters.
    • Then why does Toriel have a death glare on her face when she sees you beaten up and bruised when you make it to her house with low HP and says "You will get an apology" very pointedly, as if the monsters knowingly did something wrong?
    • Because Toriel knows that humans can't handle bullet patterns. Remember, she had an adopted human child, so it had to have been found out at some point. That doesn't mean the Froggits, Whimsuns, and other early monsters know they damaged Frisk, but Toriel will set them straight.
    • I don't buy this, honestly. The narrative tells us that a portion of the monster population significantly exceeding 50% hates humans with a fiery passion and wants them all to be wiped off the face of the earth to the point that Asgore's only going through with this genocide plan now to stop them from losing hope. There is a huge number of monsters out there who want the protagonist dead, I have extreme difficulty believing that we meet almost none of them. And if a totally normal facet of monster everyday life is what's being lethal to the protagonist, why isn't he in danger in any of the towns?
      • Don't you think Toriel would have made them give you more than an apology if she thought they were genuinely trying to murder you? You still can do something wrong even when you don't know that you are. Just because them beating up on Frisk was accidental doesn't mean she can just allow it to continue.
      • At least a few monsters don't even know what a Human looks like. Those that do include Asgore and Toriel (adopted one prior), Mettaton and Alphys (aficionados of humanity, and the latter has numerous... "research materials"), Undyne (also watches anime), and the Skeleton Brothers (Papyrus being extremely eager to prove himself by capturing one, and sans, meanwhile, is savvy enough about the timelines that recognizing a human is probably a prereq, given higher determination, and the latter's link to Time Travel). All of the above are either in on the plan at least initially, or have a clear personal reason for objecting to it.
    • All they seem to care about is actually getting out from the underground and probably destroying humans afterwards. Only Asgore gets committed to doing this but only because his subjects were so full of hope. If they were truly that desperate to kill the protagonist, you'd be seeing everyone in the towns gathering around trying to do so, but they either don't know or don't care much that you're a human. You can actually see with some monsters that they're doing what they feel is friendly, like Woshua trying to wash you, Aaron flexing his muscles, Temmie trying to touch you, ect. These don't seem to be acts of intentional violence towards the protagonist, but rather just being friendly towards them albeit not knowing they're causing damage. It's monsters like the Royal Guards, Undyne, Papyrus, ect. that are truly out for your SOUL. Also in the defense of the towns, they're talking to you, not surprising you out of nowhere.

    Light in the Garden and the Last Corridor 
  • When you reach the Last Corridor, there seems to be light shining through the windows. Everything's a blend of yellow and orange. Moments later, in Asgore's garden, you can see patches of light shining from the ceiling, as well as from another window behind his throne. Where's the light coming from? Is sunlight shining through because of their proximity to the barrier? Is it some magical or artificial lighting?
    • Considering the "Twilight is shining through the barrier" battle intro text, chances are the throne room is placed directly at the cave entrance you emerge from in the True Ending. There could be some cracks in the thinner rock ceiling by the mountain's exit causing the light in the garden, but the windows are likely facing the barrier itself, and therefore the only source of sunlight in New Home.

     Genocide Ending 
  • Other than the practical need for you to be able to play the game again, what is the point of Chara taking your SOUL? What does the modified Pacifist ending mean for the story? Is it just supposed to be a creepy reminder to the player that they murdered everyone at one point?
    • It means that, at any time the fallen can repossess Frisk offscreen and effectively nullify the happy ending by not only killing all of the free monsters (who know Frisk as their savior and someone precious to them), but now they're also above the surface to go after humanity as well (this doesn't happen in the normal Genocide ending because of Flowey destroying Asgore's SOUL, leaving Chara trapped). Effectively, the game is punishing you for thinking a reset would fix everything by showing that your attempts to make things right have just made things much, much worse.
      • That doesn't make a lot of sense to me, for the following reasons: One, freeing everyone just to then turn around and kill them along with humanity feels like the worst possible setup for a plot to destroy humanity and/or gain power from killing monsters. They would start at LV 1 when killing the free monsters, and being on the surface would mean that if monsters have truly integrated with humans, then humans would be trying to stop Chara as well (and they'd have a much easier time doing so since to them, Chara is just a child, and their intent to kill doesn't make them any better at doing so). Two, they would effectively be repeating their actions from the genocide run at that point. Making the deal for the SOUL implies that there is something greater they wish to do, despite the fact that they literally destroyed the world. Chara doesn't seem like the type who would want to destroy the world again just for the heck of it, as they themselves describe replaying the game as "a perverted sentimentality" that they don't understand. Lastly, if the post-genocide pacifist ending is really the worst possible ending, why does Flowey still tell you that the only remaining threat to everyone's happiness is your ability to reset? If this version of the pacifist ending was that different from the normal one, it seems like Flowey would be aware of your stolen SOUL and say something like "If you really care about your friends that much, the best thing you can do for them now is to bring them back, then leave and never return."
      • I'm assuming the LV "carries over" onto Frisk since Chara (someone who has not only completely distanced themselves from guilt of killing, but embraced it) is possessing them.
    • One of the WMGs suggest that Chara's goal is destroying humanity after all. Chara can't do that in the genocide ending, with the barrier still standing and Flowey's destroying Asgore's soul. It's possible that Chara didn't really destroy the world, just messing with the player like Flowey did in the normal ending (crashing the game, creating his own 'world', etc). In the Soulless pacifist ending, Chara succeeds in breaking the barrier and finally could destroy both monsters and humanity alike.

    "Behold, my mighty clone army!" 
  • What's up with the random encounter monsters? My first time through (due to a bunch of coincidences relating to the monsters I killed being the unique Snowdrake and the nameless moldbyggs) I assumed they were all unique and that killing most of them would cause them to disappear forever (which warped my perception of the game I'll admit, since the monsters came across as extremely creepy since they seemed to keep deciding to attack you literally just after being convinced you were alright). But then I saw a Genocide run LP and I got incredibly confused. Since their deaths piss people off I'm assuming they actually die, but they're then immediately afterward replaced with identical monsters with the exact same name, fighting style, physical appearance, and personality. …What's going on here? Does the monster world have some kind of clone army going on where whey clone monsters and raise them in isolation in the exact same way to make tons of identical individuals?
    • The Doylist explanation is that it's too much work to make a unique monster for every possible random encounter, especially since there's over a hundred of them taking the Genocide run. The Watsonian explanation is that they're all from the same "species" of monster, and monsters of the same species have similar attacks. This is seen when Toriel and Asgore both use fireballs, for example.
    • I get the Doylist explanation, but it really messes with willing suspension of disbelief, and it makes all efforts to humanize the monsters backfire, because they all have the same personality and even name. Surely giving them a bunch of different names wouldn't have been so hard.
    • They do probably have different names, like even though you see the Snowdrake, you learn later he's named Snowy, not actually Snowdrake. Presumably it's the same for the rest of them and they don't bother telling you because, well, why should someone about to die (you or them, depending on your run) know a random person's name? It's pretty much the same reason why Frisk spends the entire game known as "The Human", nobody asks until the Pacifist ending, so they never bother to tell.
    • That works for the ones with species names, but what about Aaron and Woshua and the others like that?
    • On that note, why can you only kill Snowy once but kill Chilldrake multiple times? Chilldrake is implied to be a single character rather than a species and has a unique personality, and seems to be a Snowdrake himself so being able to kill him multiple times makes no sense.
    • It's likely that the opposite is true. Chilldrake is the species while Snowdrake is unique. The line "Snowdrake Realizes His Name Is A Pun And Is Freaking Out" line makes it clear that he was named Snowdrake, or Snowy, and he is a Chilldrake, with there being multiple Chilldrakes in existence.

    Frisk, The Other Souls, and DETERMINATION 
  • If all Humans have the power to SAVE and RELOAD, why would the other Humans be dead at all? Couldn't they have constantly RELOAD to their last save and not die and not have their souls stolen? If they don't have this power, then why does Frisk have this power?
    • It's not said that this power is held by all humans; it's just a power governed by determination (which in this universe is both a physical matter and metaphysical concept). The other humans may not have been determined enough (if at all) to SAVE; for all we know, they only had to die the one time. This is backed up with the golf game, which talks about other virtues like PATIENCE and GRACE while referring to the color that same colored SOUL. Red is DETERMINATION, the others were different virtues that would keep them alive up to the point they died, but no farther because the obstacles they encountered were the perfect counter to them.
    • The Asgore and Sans battles both already illustrate how Determination doesn't make you 100% invincible. It's a power that only works for as long as you really want it to (assuming someone else isn't overwriting it). As soon as you give up trying, then you die permanently. Both Asgore and Sans are aware that you're fighting them over and over and dying each time, they're just trying to make that happen enough that you give up. Just imagine if one of the bosses were, to you, completely unwinnable. You can RELOAD forever, but eventually you'll have enough and just stop playing the game, which is permadeath.
    • No, they did not have the power to rewind time. In Genocide route, Flowey explicitly states that the player character's arrival was the first time Flowey's ability to rewind time had been canceled out, and apparently only one person can have this power at a time. This means the other humans didn't have enough determination because, at least according to the wiki, they embodied other virtues like patience and courage and justice.
    • But Alphys extracted Determination from the six human souls; she says it's something that humans have, and that's how Flowey gained the ability to SAVE in the first place. That's why the second explanation above (that the other humans were able to SAVE, but they just gave up on the game at some point) makes the most sense to me — unless it was actually Chara's determination we're seeing in Flowey.
    • But they couldn't save, because however much Determination they had, it wasn't enough to override Flowey's, or he would've said something about it in the Genocide route. Sure, they had some determination, just like the other humans besides the green one had some kindness and the others besides the orange one had some bravery, but they didn't have the huge amount of it that allows Frisk/Chara to overpower Flowey and seize control of the timestream.
    • You misunderstand. Flowey never faced the other humans because he didn't exist yet. Flowey was created from the DETERMINATION that Alphys extracted from the six souls in her attempts to bypass the need for a seventh. Flowey has only existed for a few years himself. He's just reset so much that it could have been centuries relative to him. We can't know for sure how strong any of the six's DETERMINATION was individually. All we can say is that it was almost certainly lower than Frisk's and likely lower than Flowey's until they were awakened and worked together to defeat him in the neutral ending.
    • They don't. A monster with a human soul becomes extremely powerful... and so does a human with a monster soul. And by falling right where he died, Frisk absorbed whatever was left of Asriel's SOUL. (Flowey has just enough of a mixture that he can save, but can't overwrite Frisk's determination.) This, by the way, is also how Frisk can get through the barrier on a neutral run. (After all, Sans can't find you, and if he can't find you, you're not in the Underground.)
      • What? No. Asriel died at the other end of the Underground, and nothing was left of his soul to absorb. Also, there is one line of dialogue from Toriel that makes it clear that all humans could reset.
      Toriel: "When humans fall down here, strangely... I... I often feel like I already know them. Truthfully, when I first saw you, I felt... ... like I was seeing an old friend for the first time."
      • Which returns us to the initial question. If the humans before could reset, why haven't they since they died? The best answer to the question I can come up with is very simple: they gave up. To illustrate: if the player lets Frisk die, and the player does not load the last SAVE or Reset the game, what happens to Frisk's SOUL? In all likelihood, Asgore claims it, breaks the barrier, and declares war on humanity. But if you press on, there is no obstacle you and Frisk cannot overcome. The six children before reached obstacles that, no matter how much they tried, they could not overcome… and so succumbed to despair.
    • It's entirely possible the magic in the Underground is why. Human SOULs don't contain magic, which is why combining one with a monster SOUL makes it so powerful – it's determination plus magic. It's possible there's just enough ambient magic energy in the Underground from monsters using it constantly that beings who are down there, with enough determination, can use this specific and relatively limited ability.
    • It's made clear that when Frisk dies and reloads, Frisk is actually dying. Giving up after being trapped in a seemingly endless time loop of being murdered and waking up, having to face your killers again and again, is not an unreasonable thing to have happened.

     Music motifs 
  • Ghost Fight, Dummy!, these songs are related to each other because they both have to do with ghosts. But why does Spider Dance have their melodies? Aside from a spiderweb for the bake sale being in Napstablook's house, Muffet and the ghosts don't really seem to be related.
    • All I've been able to think of to explain it is that ghosts and spiders are both common "spooky" symbols for Halloween and things like that.
    • Possibly because Mettaton paid Muffet to attack you, having bits of the Ghost family's leitmotif might be an tip off to show that if it wasn't for Mettaton, she wouldn't be fighting you at all. Though unless you're on a repeat playthrough, it's impossible to catch this the first time around since you don't know Mettaton is actually a ghost (Metal Crusher also has notes of the Ghost theme, but it's so distorted in the song it's hard to hear).
    • I figured that the "Ghost Family" motif was actually just the mini-boss motif, as the bass-line of Ghost Fight/Dummy! is very similar to Dogbass and — when you include Spider Dance — this results in the mini-boss themes for every major area, that has a mini-boss note , using the same motif(s). another note 

     Ever heard of a talking flower? 
  • Is there evidence that Sans is in any way aware of Flowey's existence? Was he just pretending when he brushes off the talking flower Papyrus was talking to as an echo flower? It wouldn't be terribly out of character for him to do so, and while he can't remember any previous timelines directly, you'd think the fact that he'd caused Flowey "more than his fair share of resets" would have retained in his mind somewhere. During the genocide battle with him, Sans refers to an "anomaly" that's been warping time and space; was he referring to the player and any saving/loading they'd done during that playthrough and any previous ones, or did he actually think all the horrible things Flowey had been doing were caused by you? If it's the latter, it would explain why he had plans to kill you if he hadn't made his promise to Toriel, but it would also raise a number of other questions: if he legitimately thought that all the space-time atrocities had been caused by some weak little kid, wouldn't he have stopped and thought to himself "why wasn't I able stop this from happening earlier?" Why would he treat you any differently from run to run if he always assumes you're the anomaly? And just how trusting is this guy if all it takes is one pacifist run to get him to be friends with you? Flowey mentions having done his own pacifist runs in the past, then later going against them, so why did this one make any difference from Sans' perspective?
    • There's no indication anywhere in the story that Sans knows about Flowey, so the simplest explanation is that he simply doesn't. Sans doesn't seem to have the ability to retain memories across timelines; no matter how many resets Flowey caused, Sans won't remember any of them. He's good at picking things up if he gets a hint (since he knows timelines exist), but Flowey was extremely careful to avoid Sans during the playthrough's timeline. There's no reason Sans would necessarily leap to any deductions about him based on very vague statements about a talking flower, especially not when the player is there to serve as a much more obvious source of any disruption.
    • One of the game's subtler subversions of videogame storytelling is the assumption that everyone acts with perfect information. The game goes out of its way to demonstrate that that's not the case here. Alphys' knowledge of the Core is sorely lackingnote , Papyrus doesn't realise Undyne will never be home to have a 'date' with you if you befriend him but kill her, and I'm certain Sans is talking about Flowey (mostly) in his Genocide monologue, but he thinks you're the one to blame since… well, you're the one right there in front of him with LV 19 and the crazed gleam in your eye. It's possible to take a linear path through the game regardless of how many times you die, but Flowey states he exhausted all the possibilities he could think of before you arrived, which presumably showed up on Sans' readings much more strongly.
    • If that's the case, a possible explanation for Sans' leniency with the player is that while he mistook Flowey's manipulation of the timeline to be the actions of the player, he has no way of knowing what those actions actually were. As in, he knows something was constantly playing through and resetting the timeline, but doesn't know in the current timeline anything it had been doing every time it did this. He has no reason to assume the player is necessarily good or evil — in fact, in the genocide battle, he outright states that he believes the anomaly is only doing what it's doing because it wanted to be happy. That would actually explain his actions in all possible runs of the game pretty darn well, and says quite a lot about his character to boot.
    • From Flowey's word, he's failed to beat Sans so many times that he now goes out of his way to keep Sans from realizing he exists. I imagine that Sans has some subconscious memories of the battles. Enough to be wary of a talking flower, but either he doesn't remember the flower specifically enough to actively hunt him down or knows that he's not enough of a threat that he's impossible to ignore. At least, not until you show up and give him either a (far more dangerous) accomplice or just a distraction.
    • For what it's worth, when Sans says, "Ever heard of a talking flower?", 'talking flower' is in the same yellow text that Flowey uses; Frisk says "yes" or "no" and Sans continues, "right, the echo flower" — with 'echo flower' in blue. It might just be the game reminding you of Flowey, but Sans has previously used different text colours before: when he's telling you about blue attacks and Papyrus's attacks and blue stop signs. Maybe Sans suspects.

     The Player's Gender 
  • What was the point of not giving the player character a gender?
    • The same reason they weren't given a race, age, or any real personality; they're supposed to be a blank slate for the player to project their own traits onto.
    • Except they're not a blank slate. This is the whole point of the Pacifist ending when you are told they have a name already. That you named the fallen child. Frisk is their own person.
      • How well would that reveal go over if Toby had ID'd the protag from day 1?
    • Yes, but they're still the voiceless protagonist the player is supposed to project themselves onto. Even though you secretly name the fallen human and not them, you still aren't told the named character exists until the near the end of the game, and don't even meet them until the end of a genocide run. Just because a video game character has a canon name doesn't mean they're not meant to be a blank slate.
    • Why wouldn't the player character be of undetermined gender? There's lots of other things we don't know about them — their birthday, their blood type, their favourite flavour of snail. Why would gender be any different?
    • Toby Fox in general refuses to answer any questions on the Player Character's gender, and since it tends to cause flame wars online, it's just best to use whatever you imagine that character's gender to be. It's really not that important to the game anyway.

     How has the Underground not gone unnoticed by Humans? 
  • How has Humanity not discovered the Underground? It seems like Humanity isn’t aware of the existence of the Underground or the Monsters and the War between Humans and Monsters is just an old folklore from 1000 Years ago. While the Monsters seem to have their own TV/Internet completely separate from Human TV/Internet, it seems unlikely that in the 1000 years since the war that the Underground wouldn't have accidentally been discovered by some miners, geologists, archeologists, or even policemen responding to the disappearance of one of the 6 humans on Mount Ebott. Especially since all Frisk seems to do to enter the Underground is trip and fall down a hole.
    • Whatever internet or television they have is extremely limited to the underground and may even be held back by the barrier. Throw in a once true but now turned legend fairy tale, say the mountain is cursed (or it could even be that it's a bad omen/dangerous to even attempt to climb), hence why authorities wouldn't dare go near it. There are real places in the world that have never been touched by humans for the fact that it's uncharted waters and dangerous at every turn, and it could be understandable why humanity doesn't know about it. For all they probably know, they likely know tales that say "Stay away from this mountain", but aren't sure the reason why.
      • But Mount Ebott can't be in some remote/dangerous location because of the garbage in Waterfall. The garbage is clearly Human in origin, as Alphys's various DVDs and VHS are human-made anime and inspecting the garbage gives you "there's quite a few brands you recognize". There's clearly some human town dumping their garbage on/near Mount Ebott and it's falling into the underground, which makes it unlikely that humans wouldn't have noticed something.
      • For all we know, that could be a far ways away. It is being carried to the underground by waterfall, so it's being carried by a river most likely, and we have no clue as to how far it's been carried.
    • My theory is that the Mountain itself might be a National Park or something, and thus such research (Dig into the mountain to see if there are monsters in there) would be illegal. It would also probably be viewed as insane too, like Milo Thatch in Atlantis: The Lost Empire, because people would only want to look into the Mountain when the legend is simply viewed as a 'myth'.
    • Maybe the culture that sealed the monsters under the mountain is no longer around to warn people off.
    • I'd assume it's the works of barrier magic. Maybe like something from Harry Potter that repelled muggles, but it worked for all humans in this case. Except children. The same magic also caused the mountain image (taken from the satellite) would look like a normal mountain.
    • Because no one would be able to come back out of the mountain to tell what they saw.

     Toriel and Sans 
  • It is mentioned throughout the game that Toriel and Sans were talking to each other through the door leading back to the Ruins and in the pacifist ending, the two of them meet face to face for the first time. What I don't understand is why did Toriel choose to talk to Sans through the door and not step out to see him? Or at the very least, couldn't she invite him to the Ruins to have a friendly face to face conversation?
    • She may have been too timid, or afraid her new 'friend' might report back to Asgore.
    • Pretty much, she's in self-exile so she doesn't want anyone to know who she is because she doesn't want people seeking out the former queen for any reason. Telling jokes through a door is a lot different from trusting someone with her face, especially since Boss Monsters are very distinct and she could be easily connected to Asgore. Note that she doesn't have any hesitation in letting Sans join her in self-exile in a neutral ending where she lives but the Underground goes into Anarchy.

     Toriel's soul 
  • A human who absorbs the soul of a boss monster gains godlike power. Yet if you kill Toriel, her soul always shatters; you never get a chance to absorb it (not even if you're on a No Mercy run, where you'd expect your character to grab as much power as possible as a matter of course). With Asgore, Flowey always prevents you from grabbing his soul, but there's no explanation why you were unable to get Toriel's.
    • Because at that point in time, your character doesn't know that; you don't learn it's a thing that's possible until you start reading the glyphs in Waterfall.
    • But you have determination, so you can reset and keep your knowledge (we know that this is an in-setting thing you're capable of doing because it's necessary in order to get the key to Sans' room, as well as affecting eg. some dialog with Toriel if you killed her previously). So after reading the glyphs in the waterfall, nothing stops you from resetting back to before Toriel was killed, killing her, and taking her soul with that knowledge.
    • The glyphs in the ruins never specify how the process of absorbing a soul actually works, nor does anything else in the game. For all we know, it's a lot more complicated than just "touch the floating heart thingy." Plus, we do know from the Photoshop Flowey battle that souls are still autonomous when outside the body, and if they really don't want to be absorbed by somebody, they can rebel. Call me a pessimist, but I highly doubt Toriel would have any interest in being absorbed by the protagonist at that point.
    • That's also a really strong point. On Pacifist, Toriel is alive; on Neutral, Frisk is probably still too kind at heart by that point to force another creature to serve them by absorbing their SOUL. And even on the Genocide run, Chara definitely wouldn't try to take her SOUL because they know from personal experience how two SOULs sharing a body can lead to conflicting interests, since that's what got Asriel and them killed.
    • They can persist after death. But monster souls are still magical and respond to their emotions; Toriel simply wanted to die. Her soul shattered before, reasonably, the player had time to do anything with it.

     Neutral Endings and the Barrier 
  • In the Neutral Endings, how can the Player Character/Frisk get out? He only learns after beating Mettaton that you need both a Human Soul and a Monster soul to pass the Barrier. Up to this point, regardless of whether you've been killing monsters or not, you do not have a Monster's soul. Regardless of whether you kill Asgore or not, his soul is destroyed by Flowey. Regardless of whether you kill Flowey or not, the Human souls go away and Flowey himself has no soul. It appears that the PC/Frisk has no way to actually pass the barrier, so how did they do it? You can use the popular theory that the PC/Frisk is actually dead, but then his body would've been discovered and Sans and the other characters would not bother calling.
    • This has been answered above, but the most likely is that Flowey kicked Frisk on the other side of the barrier after the fight with his empowered form, since there was way more power than a human SOUL and monster SOUL, it would have been completely in his power to have you end up on the other side of the barrier.
      • That doesn't sound like Flowey. Flowey doesn't want the Human to leave, thinking they're his best buddy in the whole world. Flowey also talks to the Human (or the Player Character) afterwards as long as he doesn't die, and since Flowey would count as a 'monster', he couldn't get past the barrier himself to do so. Combine with the fact that Flowey couldn't even get a chance to do that (how else could you kill or mercy him after the battle?), that answer doesn't work.
      • He doesn't necessarily need to do it on purpose. The whole fight was turned on its head about halfway through, and by the end of it, the SOULs rebelled, destroying Omega Flowey in the process. It's then very likely that either Omega Flowey accidentally brought Frisk beyond the barrier during the confusion of the fight, or that the SOULs let Frisk pass the barrier.
  • There is no real confirmation that Frisk ever escaped in the Neutral endings. Sans leaves you a voicemail message, and the text boxes appear on a black screen. Who's to say that Frisk didn't end up trapped underground, or even inside their own SAVE file, and died from starvation or a careless monster? The fact that you, the player, are hearing the message, and you, the player, are talking to Flowey (in the case of the Pacifist-Neutral ending) doesn't mean Frisk is still there.
  • Sans says outright he can't find you. While it might be a lie to placate Papyrus (and others), it doesn't seem in Sans's character. Frisk got out the exact same way they saved. By having a monster soul in him the entire time… Asriel's soul tainted with Chara.
    • If you spare Papyrus but kill at least Undyne, Papyrus says on the phone that Sans told him she was on a really long vacation. So yes, lying about someone's death to keep Papyrus happy would be in-character for Sans.
  • I was bothered about this for a while until I realized something. Frisk can bypass the barrier because they do have two souls with them. They have their own and they have you. We are the reason Frisk can escape the Underground in Neutral Endings, our two souls together allow them to pass through the Barrier.
    • That only works if the player is a monster. It's specifically stated that you need the soul of a human and a monster to pass through the barrier (and from a practical standpoint, this means a Boss Monster, since only their souls last long enough after death to be claimed.)
  • One possibility is that, with Flowey no longer blocking them from saving or loading, the player just reloaded and went back to before Flowey destroyed Asgore's soul, then claimed it themselves this time (now that they knew what was going to happen.) Another possibility is that before the human souls went away they gave you enough power to pass through the barrier - while this isn't specifically stated to be possible, seven souls are enough to destroy it, so it should be enough to let one person through.

     Even worth taking a soul? 
  • In Neutral, the six souls refuse to do Flowey's bidding and help you instead. Did he fail because he has no soul of his own to counter with? If not, if a soul can rebel against a monster it dislikes, what's the point of absorbing one?
    • It's not so much that the souls were "rebelling" and more that they are simply capable of carrying out their own will. When Asriel and Chara's souls fused, he mentions that he struggled to keep Chara from killing people — you wouldn't say that Chara's soul was "rebelling" against him, would you? Human souls just keep their ability to self-determine after death, and so they have to be worked with like any other rational creature. They rebelled against Flowey because he was doing something they disliked, not because they didn't like being controlled or they just felt like it. If the monster worked with the soul in some way, who knows what could happen?
    • It's possible that the monsters just didn't know that was what would happen upon absorbing a soul. The game states that it's never been done (excluding Asriel, which they apparently don't know about), just that it's hypothetically possible. Asgore might not have been able to use the souls either.
    • Maybe once upon a time, it could have been used for teamwork?
    • Or maybe, if someone has absorbed seven souls and become a god, the one who absorbed the souls gains absolute power and control over them, but not if they only have six or less.

    Asgore not prepared in Genocide 
  • A big deal is made of the fact that Alphys saw the battle with Undyne, who mentioned Asgore will be contacted to absorb the six human souls so he can crush you. Mettaton can fly and seems to know fighting you will not end well for him. Sans is right down the hall from the king, and Flowey didn't stop him even though he knows how dangerous Sans is. But when you get to Asgore, he has no idea what's going on.
    • Undyne says that Alphys should have called Asgore and told him to absorb the souls, Flowey warns him about you, he knows what's going on. He likely still doesn't want to hurt anyone.
    • ...I really don't buy that. He's totally prepared to kill a relatively innocent or even totally pacifistic child, there's no way he's going to specifically go out of his way to avoid killing a demonstrably evil one.
    • Asgore would be looking for a murderous human, what he thinks he sees is a monster, that's why he's unprepared for you.
    • There's no plausible reasons for why he wouldn't know what the player looks like after all of this went down. There are cameras everywhere, and the king, in this major time of crisis, has no business having no idea what's going on, he'd have to have watched the feed.
      • Don't forget it's heavily implied that the character's appearance dramatically changed over time. There's a lot of game (and a lot of killings) between the Lab and fighting Asgore. When Asgore sees you, it's not that he doesn't know what's going on, it's just that you're so distorted that he thinks you're a fellow monster.
      • Those were Alphys's cameras, not Asgore's. Alphys was the only one with access to the footage and she was probably too preoccupied with the evacuation to think to send it to him.
  • I think him not knowing what he should have is kind of his thing right now. Denial.
  • Here's another complication. In a pacifist fight with Asgore, you can talk to him to weaken his resolve. But in a neutral battle, it won't work. While it could be because both of you, in this scenario, have engaged in Dirty Business to get that far, it does imply that he has an easier time willing himself to harm a killer. Either Alphys went back on yet another commitment, or he was so caught off guard by what was confronting him that he froze up.
  • In Genocide, Asgore mistakes the human for a monster, which, acoording to the game's lore, makes absolutely no sense. One of the pictures shown at the beginning of the game shows Asgore leading the monsters during their war with humanity, so he should know what a human covered in monster dust would look like.
    • During the war? What wa… oh, that monster massacre, which is strongly implied to only have lasted for a day or so? Not likely that Asgore remembered such details, being preoccupied with getting everyone to safety and running for his life himself and all. And even if — it was many centuries ago and much happened since then. He wouldn't remember everything. And it's implied that LOVE changes the human's apperance just as much as physical wear and tear. Obviously during the war humans also gained LOVE — but a) there were thousands of them, not just one, and while they also killed much more monsters than the player, it was still much more monsters divided between much, much more humans and b) it's also implied very strongly that humans during the war were driven mostly by fear and prejudice rather than actual bloodthirst (heck, they wouldn't end up creating the Barrier if they started the war just for fun). While LOVE accumulates in the same way no matter the reason behind the kill (with possible exception of a Mercy Kill — I might be wrong at this point, but IIRC, killing Asgore doesn't give us any EXP), it seems to affect the person differently depending on said reasons (compare Neutral No Mercy player on 11 LV, who has no trouble killing, but never looks for a fight and can still have many genuine Pet the Dog moments, and True Genocide player on 11 LV — around the time we fight Undyne the Undying — who Would Hurt a Child without a second thought because it "looks like free EXP").

    Empty Gun accuracy? 
  • Why does the Empty Gun require so much precision if you're just bashing enemies with the gun part?
    • Possibly because the humans aren't wielding actual weapons against the monsters, they're wielding their intent to hurt backed with human power. Aiming a gun at a living thing and calculating the place where it would cripple them the most would be more purposeful in that way than just hitting them with it.
      • The projectiles look a bit like the SAVE point stars, so perhaps when Frisk is using the gun, they're actually learning to focus their DETERMINATION through it. The gun is fairly late-game content, so it can symbolise the growth of the protagonist being able to fight fire with fire.

    Blood vs. Ketchup 
  • How exactly is there any ambiguity regarding the red liquid that pours out of Sans as he's dying? Looking at it with all the information we've been given makes it pretty obvious in my mind that it can't be anything except blood. We clearly see a few drops of it come out of his mouth, independent from the slash against his torso, and the only way that could have happened if it were ketchup would be if he vomited due to his injury. Monster food is explicitly stated to turn into energy the instant it's ingested, so the idea of him even being capable of vomiting in the first place, much less ever have anything come up if he did so, is illogical.
    • Normally when humans eat food, it takes awhile for the food to be broken down, especially when it's been a big meal. While it's not exactly known how a Monster's digestive properties work aside from converting it to energy, it can be inferred that perhaps because Sans drinks so much ketchup that his Monster body is literally backlogged with undigested/unconverted ketchup. If Sans' body was then slashed, the food contents would probably spill out, which in this case is the ketchup. As for the few drops of blood on his mouth, maybe the damage cracked a few more bones in his body than it appears.
    • If that's the case, shouldn't he constantly be on the verge of regenerating HP as the ketchup in his stomach converts into energy? He doesn't drop dead immediately upon taking lethal damage; is your HP hitting zero simply an automatic, irreversible death sentence, even if you immediately get some food inside you? This seems to contradict other situations we see in the game — when you bring Asgore's HP down to zero, for example, he's wounded and incapacitated, but he's still able to hold out until either you or Flowey deal the killing blow.
    • Asgore only holds out for maybe a few seconds and wouldn't have survived anyway even if Flowey hadn't sped up the process a bit. In neutral and pacifist runs of his fight, you only bring him down to near-0 HP, and it's either Frisk, Flowey, or himself who takes him out. Also, the minute the Frisk's HP drops to 0, that's it; game over. The same could be said of nearly all monsters in the Underground who turn to dust almost immediately after their HP drops to 0, and it appears there's no recovering from it. The exception to that "almost immediately" seems to be most bosses you fight and the boss monsters themselves.
  • If we look at it from a gameplay perspective, Sans bleeding after you kill him makes a whole lot more sense. Killing Sans is the final breaking point. Once you exit the Judgement Hall, you lose control over what happens next. The character still moves on your command, but there are no more choices to make. Sans is the final obstacle, and once it's gone, the run is over. Seeing Sans bleed is what makes that known to you. A splash of color on the black and white battle screen, a sudden instant in which the pattern you are accustomed to is broken, meant to shock you into realization. The blood on Sans' mouth and chest serve as the final reminder of what exactly you've done.
    • Oh, I always understood the symbolic meaning of the blood/ketchup; nobody's arguing about that. The question here is if it's Symbolic Blood or actual, literal blood, since it possibly being the latter is sometimes important when speculating about him.
      • It really depends on your personal headcanons about Sans. I personally believe that Toby intended Sans' blood to be purely symbolic, but there have been several theories that try to explain it, which might be better discussed on the WMG page.
  • In battle screens, the only thing we see that is coloured instead of white is magic/things channelling magic, as well as the human's red SOUL. Why would ketchup be coloured red? The food Muffet pelts you with isn't coloured.
    • .....maybe the food pellets are white because Muffet is pelting you with meringues?
    • Actually, there is one other thing that's always colored during battle screens: blushing, as seen during the Mettaton quiz and both the dating scenes. And what causes blushing? Blood.

    Asriel's soul and essence 
  • When Asriel died, his soul presumably shattered, leaving his "essence" on the flowers in the garden. The game explains that the soul is the very essence and culmination of one's being, so for Asriel's essence and mind to be brought back in Flowey, wouldn't that mean that some part of his soul came back as well? "Essence" is nebulously defined in-game, but this makes it seem like it's a crucial part of the soul.
    • It's unlikely that Flowey has his SOUL anymore or even a part of it, as he is able to absorb both Monster and Human SOULs alike. A handy bit of backstory during the True Lab segment reveals that Alphys needs a vessel to absorb the monster SOULs she's preparing to use, as Monsters cannot absorb Monster SOULs just like a Human can't do the same to a Human SOUL. The most likely explanation is that Asriel's "essence" in Flowey is nothing more than an imprint, or perhaps leftover in his dust SOUL after his SOUL shatters.
    • Seems confusing. So the "essence" is leftovers of the SOUL? Then isn't that technically part SOUL? Or what is an "imprint"?
  • And even though Flowey states that he can't feel anything, the endings appear to change that. In a Neutral ending, sparing Flowey causes him to cry and run away. At the end of Genocide, when he realizes his predicament, he begins shaking in fear, saying "What's this feeling?", which shows that he hadn't felt fear for a long time, possibly not since he first woke up. Then when he meets Asgore, he's said to have been crying, and he cries again at the very end, when he switches to his real face and voice. In the True Pacifist ending, when Flowey returns in the end, he still seems to have some lingering compassion, as he asks for the player to either let everyone be happy, or erase his memories.
    • Flowey does feel emotion; however, he lacks empathy as a result of not having a SOUL and soon loses whatever compassion he had when he starts experimenting on the residents of the Underground in violent ways, which makes him into the creature he is by the start of the game. Like Flowey had said, he got scared about what happens when dying without a SOUL, and that appears to be the last time Flowey experiences fear before Genocide. It's unclear to me whether or not Flowey actually reverted to Asriel or not by the end of Genocide, but I wouldn't put it past him since he's truly scared of what his adopted brother/best friend is about to do. Flowey at the end of True Pacifist regains a sense of compassion after the fight because of the combined SOULs allowing him to do so temporarily, implying that one needs a SOUL to have these. Most likely it will fade away from Flowey again or could just be the memory of compassion.
    • Flowey can't feel empathy or closeness to others, but he can still choose to live by Asriel's moral values. He does that for a long period of time before going mad from the trauma of his violent death and loneliness of living as a soulless flower. The events of the True Pacifist ending heal him enough to change his mind about his 'kill or be killed' philosophy. Flowey decides that the others' well-being matters to him, even though he can't relate to their emotions or feel the warmth of kinship anymore.
    • Flowey appears to actually care about Frisk and the others after the True Pacifist ending. If not, then why would he decide to live by Asriel's moral values? And if the others' well-being matters to him… does that mean he cares for them? Is that the same as empathy?

  • The nature of souls is also a bit confusing, especially in this situation. A book in the Librarby says that monster souls are thought to consist of love, mercy, and compassion, although may not be true because human souls can exist even without those things. Additionally, some monsters have shown a lack of some of these things, such as the Mad Dummy, who attacks without mercy and angrily berates/fires his minions. Asgore similarly refuses to let himself or Frisk show mercy to the other in battle. Wouldn't that mean that Flowey could still have somewhat of a soul, even without demonstrating kindness?
    • The nature of SOULs is indeed a little confusing, but this troper believes the reason for the difference between Human and Monster SOULs in what they consist of is the fact that Monsters are solely composed of magic/their SOUL, while Humans are grounded in more physical bodies, hence why humans can go without those. The Mad Dummy is merciless at you but because of a misguided (or possibly actual) thought that you did some pretty terrible things to his cousin, showing that he has compassion and love for his cousin. Asgore shows no mercy because he doesn't want to kill Frisk, but must because it puts everyone in the Underground with high spirits. Again, he shows compassion and love. Flowey on the other hand has no compassion or love for anyone except perhaps Chara, and does not display any sort of mercy unto others, only asking for it when frightened for his life. It's only until he becomes Asriel that he regains these things if only for a short period of time.

     Why Not Just Capture The Last Human? 
  • This applies more to Undyne than to Papyrus since Papyrus is a Minion with an F in Evil, but instead of challenging you to a fight, why don't the boss monsters just grab the human child, incapacitate them so they can't fight, stuff them in a Bag of Kidnapping, and sling them over the shoulder to take to Asgore? That way the risk of any monsters dying due to the child's violence becomes minimized, if humans are as dangerous as a few monsters claim, and Asgore can break the barrier more quickly. Undyne has the physical strength for it, and Papyrus can lock you up in his garage if he lowers your HP, but Undyne makes it a point to fight you and give you a spear if you try to run. Surely the need for a Combat Pragmatist would win over Honor Before Reason, especially since other children have killed monsters in the Underground.
    • Undyne isn't a Combat Pragmatist. She's a hardcore anime fan who's more focused on looking cool than actually getting the job done. As for the Bag of Kidnapping plan? Who's to say that she wasn't planning to do that after (presumably) knocking you unconscious?
      • Because there is a character who is planning to kidnap you after knocking you unconscious: Papyrus. Rather than dying, you pass out once you reach low HP and he takes you to the shed next to his house to recover. It's genuinely not his fault that he doesn't know the proper spacing between bars required to trap a human, having never seen one, so out of everyone in the game he actually does the best job at the whole human-capturing thing. Either way, the process is distinctly different than when Undyne kills you, and the fact that Papyrus is capable of stopping before you die so quickly means monsters can absolutely tell the difference between wearing you down and just killing you, so Undyne absolutely should be able to tell.
      • Undyne isn't trying to knock the player unconscious; she makes it abundantly clear that she's actively trying to kill them. While she has a sense of honor and flair and she's influenced by anime, her Hot-Blooded personality isn't just an act.
  • In Toriel's case, why not take the child to their room and lock the door while they are sleeping so she can destroy the exit without interruption, or destroy it as the child confronts her instead of giving them a chance to prove themselves? She doesn't want you to be unhappy, but she doesn't want the other monsters to kill you either.
    • For starters, the door to the child's room may not even have a lock. More importantly, Toriel's plan seemed to be that she wanted to make you so happy that you didn't want to leave. And you're given many hints during your brief tenure with her that she really doesn't want to hurt you. Tough as she may seem, she's as big a softy as Asgore.

     "You're hurting me, please stop!" 
  • I've heard people say that an undisclosed number of the random encounters aren't actually trying to hurt you, they just don't realize their bullet patterns are lethal to humans. If that's true, why is the option of essentially saying "you're hurting me, please stop" only a dialogue option with the Vulkins? Furthermore, we know for a fact from Toriel's reaction if you arrive at her house with low HP that bullet patterns cause visible physical damage to the child, so why do none of them have any reaction whatsoever to their bullet patterns causing nasty cuts and bruises? And this is assuming that Frisk's possession by Chara makes Frisk as emotionally dead as their sprite appears to be and that they aren't constantly crying out in pain from getting injured like any normal child would.
    • I feel like the monsters must surely KNOW that their abilities hurt humans. You can read in the "librarby" that they are aware of humans' lack of innate magic, that humans are mostly water, and that magic is empathic in nature, so it just doesn't make a lot of sense to me that they wouldn't know. There could be other explanations, but none of them REALLY answer the question of "why can't we just ask them to stop?" Still, I'll voice them here in case they give other people ideas:
      • Maybe some Monsters just aren't intelligent enough to understand the harm they cause? There are only a few examples of this I can think of (Vulkin, Greater and Lesser Dog, and Temmie) where this is plausible.
      • It makes more sense to me that the Monsters are genuinely afraid of you (you're a human after all) and attack in a misguided idea of self defence — so they might not believe you when you ask them to stop — they could think you're faking it, or lying to them. After all, their history shows that humans are violent and dishonest.
      • Aaaand the most horrid idea I can think of is that Frisk just doesn't tell them because they don't want to be spared. They never give an explanation of why they went up Mt. Ebott in the first place, but there is an implication that they went there to die. But somehow they survived, and out of mild curiosity, or perhaps some glimmer of hope, decided to continue. Frisk is obviously unusual in many ways: they don't react as any normal child would react in the situation they're in. Maybe all along Frisk thinks they're in some kind of purgatory, or simply just… don't wish to fight back because they vaguely hope that the next monster will successfully finish them off. Still, they're kind-hearted, and while they don't value their own life (at least not at first), as they go on, they still bond to others around them and thus, continue to interact and befriend them. Truthfully, if any of this has any merit, then I see a lot of echoes of the struggles of depression in Frisk. They're in this dark place I can relate to where they're not actively seeking out death any more — but they're also not doing anything to avoid it. That kind of refusing to tell others your pain because you don't think you're worth saving is, sadly, something many can relate to, as is the glimmer of not-quite-hope that we give ourselves when we manage to hang onto our curiosity and desire to learn about those around us. (tl;dr Frisk was suicidal and didn't WANT the monsters not to hurt them, and the monsters are too Cloud Cuckoolander in comparison to humans to understand.)
    • That last one sounds suspect. Frisk is basically immortal, there's no way they're a Death Seeker, or at least that attitude wouldn't last past the first revival. If they wanted to kill themselves, they probably wouldn't want to put their blood on another's hands if they had any ounce of decency. I also don't buy that the others are afraid of you, because few if any of them act anything remotely like that. Whimsun and Froggit maybe, but Aaron? Snowdrake? Their ridiculously casual behavior while attacking you doesn't make much sense if they're afraid of you (though to be fair, that behavior also doesn't make much sense with much of any interpretation other than that they're completely batshit insane).
      • Maybe not a Death Seeker, per se. I don't really think it's that clear cut. But suicide is definitely implied to be one of the possible reasons Frisk went to Mount Ebott in the first place, so I still think it's plausible that they actively chose not to fight back — perhaps not because they were seeking death exactly, but because of any number of reasons, ranging from it being a form of self harm, to a lack of pain awareness, to just... Them being a person who is somehow alive, when they expected not to be, going along with events and seeing what happens because honestly, what else are they going to do? They probably expected to be dead, it's not like they knew they were going to turn out to be quasi-immortal, and it's not like they had a plan here (which could also explain the "they have decency" point — obviously being suicidal doesn't mean you want to harm or cause others to harm you, but Frisk can RESET and they know it — so it's not like the monster responsible would be killing them really. They'll just make it so it never happened.) It takes an extreme amount of... Well, determination to not at least raise a hand to defend yourself. But that kind of behaviour (speaking from actual experience here I'm afraid) is not uncommon in those with extreme problems in self-esteem.
      • And while we don't know their age, it can be assumed that it's not normal for their age group to Flirt with basically anyone (slimes, goats, skeletons, fish ladies, etc), much less having the option to choose to call Toriel "Mom", THEN Flirt with her. They may not have had a particularly warm home life, and ended up with a somewhat… confused view of familial love. Papyrus' pre-boss battle speech sounds like it's just a bait and switch gag of him not wanting to admit he's lonely, but he has shown to be more observant than he appears at first glance: for example, being competent enough to be able to stop the fight immediately upon you reaching 1hp, when even Toriel can kill you; or when he uses reverse psychology to challenge Undyne to befriend Frisk. It's not impossible that Frisk really did have "A DESIRE TO HAVE A COOL, SMART PERSON THINK YOU ARE COOL." Low self esteem might also explain why they would call Toriel their mother, yet also be willing to run away from the ruins so soon. They may simply believe they aren't good enough for her. ...If true, it makes Papyrus' geno-speech simultaneously even more heartbreaking and more heartwarming

     Who is talking to you during the 'Game Over' screen? 
  • Sorry if this is really obvious, but it's been bothering me. But when you die, a voice says, "[Insert Name Here], don't give up hope!" "Stay determined!" or variations thereof, then you can start what you're doing again before you died. Who exactly is speaking? At first I thought it was Flowey (since he needs you for his plans), then I thought it was Sans using his "serious font", then I started wondering if it was Asriel. (Since it's implied he's the one who talks to you when you fall into the Garbage Dump.) Hell, it could be Toby for all we know, but I thought it was an interesting touch of the game that when you hit a Game Over, the game encourages you to keep going. It seems like Flowey might be the most likely candidate, since he's the only one who can talk to you during any possible time you die, as the first character you meet. The font and sounds make Toriel an unlikely choice.
    • I believe I heard somewhere that it's the fallen child having a flashback to Asgore talking to the poisoned fallen child and begging him to hang on.
      • You are correct. Voice bips in the game over screen is the same as Asgore's and in the True Lab, you can find video tapes. One of them has Asgore using the same words from the game over screen to the fallen child, who grew ill, which also explains why it's their name and not Frisk's.
      • Also, the game uses the same deep-voiced text sounds for the death text that it uses for Asgore.

    Every monster SOUL 
  • So Asriel is able to destroy the barrier because he has six human SOULs and every monster SOUL, which is literally equivalent to a human SOUL. But Mettaton and Napstablook canonically hid inside and weren't absorbed by Asriel. Does that mean ghosts don't count as monsters? Does it mean they don't have SOULs?
    • Mettaton was absorbed, he knows Frisk's name when you go talk to him. Napstablook doesn't because his soul wasn't inside Asriel when Frisk told him their name.
    • It's likely just you need only need NEARLY every SOUL to equal a human SOUL and can get away with missing one or two. But the buffer might be so thin that Flowey only even attempts to absorb them all if he knows it's a True Pacifist run so he has the absolute best chance to succeed since he also can't hope to try again if it fails.
      • You are indeed correct; in the waterfall segment of the game, the panels giving you backstory on the great war between humans and monsters notes that it would take nearly every monster SOUL to match a single human SOUL. It's a common misconception that people think you need every single monster SOUL, and this troper assumes it's because the fine print of the sentence is glossed over.

    EXP and LOVE 
  • Why does Sans give you so much EXP? Gameplay-wise, it serves as a reward for the absolute hell you just went through, but honestly, a monster with 1 HP should give you maybe one or two EXP points, not 5000. Is there a rational reason for this?
    • EXP and LOVE is a measure of the intent to you aim to kill someone with; given the hell he put you through, it's safe to assume the final blow is delivered with such a massive amount of killing intent that it causes your EXP to skyrocket.

    Is Frisk Aware of Resets? 
  • This may be impossible to answer, but it is... unsettling... to think that a child is experiencing death over and over again against their will, even if it is to rescue an entire race from their prison.
    • I don't have any proof of this, by I took Frisk's sprite's utterly deadpan expression (compared to the incredibly lively expression in the opening sequence and in promotional art) to mean that Chara's possession of Frisk rendered them emotionally deadened and disconnected and kinda generally out of it. Though this doesn't explain the trolling pranks you can pull on people or Frisk's cute interactions with Toriel, which would be creepy if they were emotionally deadened.
      • There's a lot of evidence that Frisk is indeed aware of resets — at the very least, they're aware of save files. They must surely see the save file being destroyed by Flowey when you reload the game after You/Flowey kill Asgore. During the Battle with Asgore, you can also tell him how many times he's killed you so far. If you reload from a previous save after accidentally killing Toriel so you can undo it, you see the comment: "you think about telling Toriel you saw her die... but... that would be creepy." And most damning for me is that near the end of the game,
you have an exchange with Sans:
Sans: besides haven't I done a great job of protecting you? Look at you, you haven't died once.
Sans: What's with that face? Am I wrong?
  • That's also what makes the True Reset so absolute, it wipes everything, not just Flowey's memories, but Frisk's as well. After all, if Frisk is still themselves from the end of the Pacifist ending, there's no way they'd willingly go along with you starting a Genocide run. Doing it requires that Frisk be a blank slate and, in retrospect, makes doing a True Reset an even worse Kick the Dog moment than originally percieved.

    "Suddenly I won't let you hurt the humans!" 
  • So... what's with Undyne's behavior in Genocide run? On every other run she is totally willing to kill human children to give Asgore the power to wipe out all of humanity. Even if that's not her primary objective and she just wants to return to the surface, she clearly doesn't care anywhere near enough about the wellbeing of humanity to actually fight to protect them. So why does that suddenly change once she's confronted with the most psychotically, irredeemably evil human being she could have possibly met? Why does that, of all things, make her suddenly decide that she wants to fight to protect humans as well as monsters?
    • I think it's implied that Undyne knows humans can't be all that bad? At the very least, she doesn't think every human deserves to die because of one homicidal maniac. She says on pacifist that she "used to think humans were cool" so it's not that she was biased against humans, so much as she felt killing them was the way to earn Monsters freedom; along with a fair amount of (kind of justifiable) anger that they caused such harm to people she cares for. A lot of Undyne's behaviour is bravado. She tries to be 'the hero' and the way she convinced herself that was what she was in the Pacifist Run was by making the invading human into an enemy worthy of her anime-inspired speeches -hence her ever increasing frustration if you refuse to fight back or run: you're not letting her keep up that self-delusion. Once she sees that, she realises she's standing between you and destruction of everything and, fittingly, that's the moment she becomes a real hero.
    • It's pretty apparent in all routes that Undyne has a love/hate relationship with humans; while she is angry at them for what they did in the past, she exaggerates this anger to the point of Fantastic Racism before you become friends for the sake of looking cool and heroic. In a moment of seriousness like in the Genocide route, she's able to set both her pride and her anger aside and adopt the mentality of "whatever evil things humans did in the past, they don't deserve to be mindlessly destroyed by the likes of you". It's also worth noting that Undyne has caught on to the fact that you've become something neither human nor monster by that point, which probably helped her reach that mindset.
      • Undyne is a Hot-Blooded, anime-obsessed, over-enthusiastic heroine, with extreme self-confidence (even to the point where she is able to produce her own determination, a substance normally only found in humans). She has a strong sense of right and wrong, and when confronted with a creature that plans to destroy, not only the monsters that she defends, but the humans that she 'studies', of course she would do something. Undyne would never stand by and let you destroy everything she loves. Now that you are a real threat, rather than just the last piece of the puzzle she's been building, she would dive into hell if she thought she could drag you down with her.

     "Freeing" in the Genocide run 
  • Why does Flowey say "Let's free everyone, and show them what humanity is really like!" to you during his speech right before the final boss of the Genocide run? His plan was for everyone to die; how exactly does that allow him to break the barrier (and even if he did, who would be left to free)?
    • His plan was for you two to play together forever. After you killed everyone, you could (in theory) reset and do it then, since Flowey retains his memories with normal resets. Remember, he's been trapped there forever, and he didn't expect to be murdered by his childhood friend, either.
    • No, he didn't mean freeing in the literal sense. He was being much darker. It's an explicit callback to the prophecy represented by the Delta Rune. As Gerson says when he explains the rune: "Legend has it, an 'angel' who has seen the surface will descend from above and bring us freedom. ... Lately, the people have been taking a bleaker outlook... Callin' that winged circle the 'Angel of Death.' A harbinger of destruction, waitin' to 'free' us from this mortal realm..."

    In My Way 
  • In the Genocide Route, you encounter Monster Kid on the bridge in Waterfall. He tries to stop you from proceeding, and you hit him with a devastating blow (this happens even if you use a strike that would normally be weak). Undyne takes the hit, tells Monster Kid to leave, and transforms into Undyne the Undying. Cue badass music and the hardest fight in the game up to that point. My question is, why does Chara continue to land a killing blow on Undyne, despite knowing what will happen? Surely, attacking Monster Kid with less force, or perhaps a false hit, would draw Undyne into attacking you, and you could kill her in her normal form.
    • Wait, what? Why would Chara know what's going to happen next? They can't see the future.
      • Well, unless you beat Undyne the Undying on your first try (which is nigh impossible because of the difficulty of the fight), you will be fighting her over and over. My question is, after realizing that attacking Monster Kid will bring Undyne's wrath upon them, why does Chara continue to do so?
    • Because Chara represents thirst for LV and EXP, no matter how cruel or hard it may be. Also, you CAN attack Monster Kid with less force, but it always ends up transforming Undyne into her Undying form. Not to mention, how do we know that it wouldn't transform Undyne into her Undying form? From her perspective, you killed basically everyone before that, including many members of the royal guard and her Adorkable Nice Guy of a friend who actually gave you a chance and now you (again, from her perspective) attempted to kill an innocent little kid. She would most likely still feel the need to stop you and her determination to do that wouldn't let her die. That's how I see it.
      • So, to elaborate on that, Chara's thirst for LOVE and EXP are so strong that they can't resist attacking full force, even with the knowledge that attacking Monster Kid will bring on a much harder fight. Yikes.
    • Another possibility is that it isn't Chara attacking full-force, but rather, Frisk, reaching out to try and stop Chara (and YOU) before it's too late, in any way they can, even if it means dying over and over again.

  • How was Flowey able to absorb the SOULs of all the monsters in the underground without killing any of them? To directly quote Alphys' third lab entry, "But extracting a SOUL from a living monster would require incredible power... Besides being impractical, doing so would instantly destroy the SOUL's host." Obviously Flowey has the "incredible power" part down, but going by the game's own words, none of the monsters should have survived that.
    • Flowey was able to save and reload with only six souls, he easily could have done it again to bring everyone back.
    • Wouldn't that have also undone the act of breaking the barrier?
    • Remember that at this point of the game, Asriel is in fact, a God. A god with a really silly name, but still a god. In the end, Asriel's last acts are to destroy the barrier, then restore everyone's Souls back in their physical forms.
    • Flowey was specifically designed to absorb souls from both humans and monsters. Monsters, as we know, are made almost entirely of magic Asriel, with his all-but-divine powers could easily expel enough magic to rebuild them as long as their souls are still intact. He couldn't do the same for the six human souls, apparently, either because they were already dead or because he couldn't make fully physical bodies to support them.
      • Or maybe because the power from those human souls ended up becoming the magic that formed every monster's body after that was said and done.

     Neutral Ending Final Boss 
  • How does Photoshop Flowey have mechanical/machine parts? The goat/sheep face parts make sense, because of Asriel, and the overall shape seems to allude to the Determination Extractor, but in the Neutral ending, Flowey only has the six human souls to use for power, and the boss fight takes place in the barrier chamber. There's no machine parts anywhere, so where do they come from?
    • With his newfound god-powers he could make himself look like anything. He's really just using magic to change his appearance.
    • It's been theorized by others that the mechanical pieces came from the True Lab, with the DT Extractor making up the physical face of Photoshop Flowey, the TV used to watch the Dreemur's home videos used as Flowey's TV Head, and the air ducts making up the 'body'.
      • Lends itself to some pretty awful Fridge Horror there. It not only suggests that Flowey strongly recalls what happened to him in the True Lab, but also that with all that extra power from the other souls, he was able to pull up pieces from the True Lab to incorporate into his new form by digging his roots under it. Which begs the question: where did those weird fire-spouts come from...?

     Breaking the Barrier 
  • Seven human souls are needed to break the barrier. But, are the souls supposed to come from dead people? If not, why did Asgore and Undyne have to kill Frisk in the first place?
    • "Seven of the humans' greatest magicians" cast the spell to create the barrier, a power equivalent to seven human souls is required to undo it. They could have taught a child how to use magic and cast the counter-spell simultaneously, but it may have taken years if it requires the skill level implied. It's much more convenient for a skilled, experienced monster who uses magic naturally to do it alone within a few seconds. If Asgore could have taken care of Frisk (like he wants to if you spare him), he may have taught them how, but a certain someone wouldn't let that happen.
    • They wouldn't have to train one human mage, they'd have to train seven to work simultaneously from scratch. A much more demanding task. Not that it matters, since out of all the time they've been under the mountain, only a handful of humans have fallen in, and only very rarely at that. So even if they managed to convince and train a human to aid them, they'd run into the problem that there's no guarantee that the required number of humans would fall down within any one human lifetime. That's not even counting the possibility that a trained human wizard could turn on them using their soul-powered magic and physical superiority to overpower them. So containing souls until they got the required number underground is a more feasible solution. It's not a good one and, as Toriel angrily pointed, it ignores the much more pragmatic solution (i.e. letting one monster take a human soul, leave, collect six others in whatever way necessary, and come back within a far more reasonable amount of time), but it is what Asgore could come up with in his weak-willed state.

     Snow in Snowdin: How? 
  • How is it possible for there to be snow underground? Especially since the only known holes to the surface are a one-way fall into the Ruins and the Barrier?
    • Presumably the cavern is high enough that it has its own weather. There are caves in the real world high enough that they get clouds and rain. I'd be more curious about all the trees — we might have to resort to "magic" as an explanation for that.

  • How exactly are cellphones able to operate in the underground? Surely they'd get zero reception due to being deep under a remote mountain, too far from any towers to receive signals? Unless the underground just uses wifi throughout the place.
    • The underground apparently has its own private internet, so the latter would make sense.
    • Many of the caverns are quite expansive in their own right, so they may just have their own cell towers lined up. Only the narrower passageways would need a denser network.

     "Chara" in the True Pacifist Ending 
  • What makes Flowey/Asriel believe the protagonist is Chara in the pacifist ending? The only other time he gets that idea is in the genocide run (when he's apparently correct). In the neutral endings, he makes a point of the fact that you're certainly not "the one person he cares about," and it seems that the more violent you are, the more he sees Chara in you. So why does he suddenly seem so sure of this when you're doing the run in which you may have never once killed anyone?
    • If you look at the sprites for Chara and Frisk, they have identical outlines. Plus, Flowey/Asriel has only seen about five or six humans in his life, so of course he'd assume any humans that look alike are the same human wearing different clothes. Plus, Chara was probably his only friend in life, being his sibling, and wouldn't you miss your sibling if you relived the same few days/week/months over and over and over again?
    • Asriel also admits at the end of the Pacifist route that he knew from the beginning that Frisk wasn't really Chara, he was just projecting onto Frisk because he desperately missed his friend.
    • Actually, Flowey only realizes Frisk is Chara in the Genocide route because killing everyone in the Ruins is an act that only a soulless person would do. Because Chara lost their soul alongside Asriel's when they died, Flowey expected Chara to — just like him — be soulless should they return. As for him confusing Frisk for Chara, it's exactly what the user above me said: Asriel is projecting his relationship with Chara onto Frisk, possibly because him finally recovering his original body made him feel really nostalgic.
    • Flowey probably detected Chara's soul-phylactery thing on Frisk that attached onto him the moment Frisk fell onto the patch of flowers.

    So, about that narrator theory...  
  • I know we're veering into fanon here, but after looking at the evidence, I have to conclude that some variant of the "Chara is the narrator the entire time" theory is the most likely from a canonical standpoint. I really want to wholeheartedly believe it, but there's one specific thing about it that's keeping it from making sense to me: if it were true, then Chara's attitude would have absolutely no middle ground. You can be slaughtering people left and right, up to an including Chara's own adopted parents, but as long as you're not on the path of killing everyone, the narration will still still follow the same goofy/encouraging/funny routine that it would if you hadn't been killing a single thing. Weirder still, you could be on the Genocide route for the majority of the game, "Chara" giving their psychopathic harbinger-of-destruction narration the entire time, but as soon as you let one monster slip by, no matter how insignificant, suddenly its jokesy fun times again. Heck, "Chara" sort of comments on this if you get through Snowdin without killing Snowdrake, calling the act of forgetting him a "failure" before resuming the normal narration. It's almost as if "Chara" somehow knows that they can't be brought back at the end of the game unless the dust of every single monster is on your hands, and the aforementioned comment means that they're hoping/planning for you you doing so, which completely contradicts the non-evil personality their normal narration suggests. And it's not like "Chara's" corruption in the Genocide route is a slow burn either - they'll be demanding to know where the knives are as early as the Ruins, and by the time you get to Papyrus they'll be calling the act of potentially killing him (which is possibly the single most common "I had to stop Genocide when I got here" moment in the game) "forgettable". This wouldn't bother me so much except Undertale is populated exclusively with major characters that are nuanced, dynamic, and believable - if the narrator theory were true, then Chara would be a very blatant exception from that rule, with actions never affecting their personality even slightly no matter how traumatic or heinous, until you complete a very specific set of actions then suddenly they're completely different. I know the other theories have bigger holes in them, but that doesn't mean the narrator theory, at least in my mind, makes very much sense either... anyone have any input that could help resolve this?
    • The narration when checking objects in Toriel's house becomes pretty morose if she's dead, and there's very little narration at all during the fight with Asgore, so they are affected by killing them at least. They also seem dismayed by Undyne's death and regard the bag of dog food in the lab as "half-empty" rather than "half-full" if you kill even one monster. But it would still make sense even if they didn't show any reaction at all; they have no soul of their own, and are looking to Frisk (and you) for guidance as to what their purpose is now that they're "resurrected"; if that purpose is to kill monsters, so be it. The narration reverting back so suddenly if you abandon a Genocide route is probably just a limitation.
    • Asking where the knives are in the Ruins during a Genocide run is probably because in said run, by the time you reach Toriel's house you've just finished hunting down every last monster in the Ruins. In a Neutral run, you don't kill all the monsters. In Genocide, you devote yourself to killing every single monster you come across. Anything else is likely just a limitation of the game.
      • Actually, the narration only regards the dog food bag as half-empty if you kill at least twenty monsters, and find it funny if you kill twenty monsters plus Doggo.
      • No, the dog food bag is regarded as half-empty the moment you kill a single monster, though you are correct about when it becomes funny.
      • In a weird way, it makes sense if you think of Frisk, Chara and "the anomaly" (you, the player) as a Freudian Trio, with Frisk as the ego, Chara as the superego, and the anomaly as the id. Chara provides the memories, the narration and the 'rules' of the game, and is a bit emotionally detached from the game as a whole (with one exception), while the anomaly fills in with emotional whims, which — depending on the player — can run from "Let's save everyone!" to "Let's kill everything in sight". Frisk, as the ego, reconciles the narration/rules with the player's impulses. So when the narration gets blunt and morbid, it's not really Chara — it's the anomaly. It's you and your decision to kill everything.
      • That doesn't make any sense — the blunt and morbid narration uses first-person dialogue when referring to situations only Chara has been through, like sharing a room with Asriel and drawing the flower picture.
      • The blunt and morbid narration is Chara, because Chara is the narrator. Their narration style changes from blunt and morbid to quirky and helpful depending on whether or not you're on a Genocide or Pacifist run, which you — the Anomaly — have the power to choose from.
      • There actually is a reason why Chara's outlook is so moldable — they, like Flowey, have no soul. It was fused with Asriel's when they were attacked by the humans, and so they both died together. This caused both of them to come back soulless. Without a soul, Chara doesn't have the empathy that should be telling them that killing is wrong — after all, they did die as a result of Asriel refusing to fight the humans that attacked them, even for self-defense. So it's up to us to teach them. If you go through the game without killing anyone, even in self-defense (like during Undyne's fight), then Chara will be reassured that Asriel's decision not to kill in self-defense was right. However, they won't share details of their past with you like they do in the Genocide narration in New Home because they still consider Asriel to be their best friend. But if you kill even one monster, that shows them that there are situations where killing is justified, proving Asriel wrong. This causes them to consider you thier best friend, and share some of their past with you. However, they become pessimistic. If you kill over 20 monsters (plus Doggo), they will become numb to the idea of killing, possibly even to the point of becoming sadistic. This is because the more monsters you kill, the more EXP and LOVE they gain. Since those things numb you to the idea of killing, they wouldn't be as affected by it, even if they still had a soul. However, they still go quiet on the fights with Toriel and Asgore, not wanting to fight their family, and they hesitate before killing Asriel — YOU are the one who prompts them to kill thier brother.
      • Can you point to me evidence within the game that Chara came back without a soul? Their soul didn't fuse with Asriel's when they died, Asriel simply absorbed it into his own body, along with his own soul. If absorbed souls are forcibly 'fused' with their host, then the ending of the Omega Flowey battle wouldn't have been possible.
      • Humans can't absorb human souls. If Chara still had a soul, they wouldn't be able to fuse with Frisk at the beginning or take their soul at the end (without soul of their own they'd no longer count as a human themself). Also, Chara explictly states that Frisk absorbed their essence — and essence is something completely different from soul. Their soul might have survived and probably did, but it still got separated from the body and essence, and thus once they are awakened, they don't have soul (as in, it's separated from them, not destroyed).
      • No matter how Chara and Asriel's souls were configured when they died, they still both came back soulless. Flowey even says this when you meet him at the end of a Pacifist run. However, we don't know if their souls survived their body dissolving into dust.

    Delta Rune before the prophecy? 
  • In the game, Gerson says that the Delta Rune symbolizes the prophecy, where an Angel who has seen the surface comes to free the monsters from the Underground. However, at the very start of the game, the first thing we see that begins the story, is a Boss Monster wearing the Symbol. This was before the War that forced the monsters into the Underground in the first place. On top of that, Gerson mentions that the Symbol existed before recorded history, but the Monsters haven't always been Underground. So what was the Symbol supposed to mean before that?
    • Maybe the symbol was never intended as a prophecy. It could have meant nothing at all, or its original meaning could have been lost to the passage of time.
