General and Fan Content
- Let's start with a meta example: The moment when you find out how far the game goes in knowing what you've done through Save Scumming, particularly with Flowey's speech at the end of the Ruins.
- During the No Mercy route, a few NPCs still stand up to the player:
- Gerson, the turtle shopkeeper in Waterfall, openly trash-talks you because he knows you can't kill people in the shop screen, so there's absolutely nothing you can do to him.
- While it's obvious that Burgerpants just doesn't understand the gravity of the situation, threatening him leads to him smoking a cigarette and smugly replying, "I can't go to hell. I'm all out of vacation days."
- Despite being scared shitless, Monster Kid stands in your way to keep you from hurting other people.
- During an interview about NieR: Automata, Taro Yoko mentioned Undertale by name, saying what he had seen of it seemed very interesting, and requested the game be given a Japanese translation so that he and others there could play it. It's definitely amazing how huge the game became after such a short while.
- The game is so emotionally touching that Dragon Ball Z abridged's Vegeta couldn't even play the game after completing the first area.
- Mortis Ghost, better known as the creator of the game OFF, has done fanart of the game. Given that Undertale draws a few inspirations from OFF this makes it doubly as amazing.
- Ben "Yahtzee" Croshaw was so impressed by the game that at the start of his Zero Punctuation Top/Bottom 5 Games of 2015 video, he shoved in a 10-second "review" of the game so that he could include it in the listnote ... and then plopped it square at #1 Best.
- Yahtzee is a man who's been so worn down and become so cynical in gaming, his "Extra Punctuation" review where he praises the game's writing and message, even going so far as to say it made him emotional, is just incredible in its passion.
- While kind of creepy, there is a layer of awesome to the fact that Gaster is managing to REFORM himself, after being scattered across space-time. WITHOUT DETERMINATION. Gaster doesn't need Determination - he is just that powerful now.
- The crossover that nobody asked for.
- This fanmade battle against Genocide!Alphys is equal parts awesome, tearjerker, and funny. Alphys has augmented herself with DETERMINATION-fueled cybernetics, and boy, does she deliver a pounding. Her attacks are a combination of Gaster Blasters from Sans' fight (presumably they were left scattered in storage at the True Lab), Mettaton's floating robots and bombs, his rewinding abilities, and some of them are even direct references to various classic video-games. On top of this, she even uses the dreaded tile puzzles as attacks! And this isn't even mentioning the music that plays throughout the fight; it really shows that even if Alphys hadn't become the leader that she became in the Genocide route, she took a major level in badass regardless.
Alphys: What is this feeling? I know what it is...it's hatred, for the person who came so far just to hurt an innocent monster.
- To top it all off, the fight comes to a close in a similar vein to Genocide!Undyne's: feeling intense pain throughout her body, she outright refused to die, and pushes out one last barrage of attacks — including the constant time-warping — in the hopes of beating you.
- If you taunted and kept trying to eat the pie in her fight, when you deliver the final blow, this happens instead:
- In other words, Alphys will channel Andonuts and use PSI Anime B to kill you.
- This video set to Run Boy Run by Woodkid is an amazing testament to how much The Child goes through in the game.
- Undertale Red, a short fanmade edition where you have one fight against a strong monster named "Red" (whose look draws from Little Red Riding Hood), and the game has eight different endings depending on what you do. If you stay Pacifist, she gets serious.
Red: Keep that garbage to yourself!Red: You're a human! Our last key to freedom!!Red: WHY WON'T YOU FIGHT BACK?!?
- Move over, Pacifist! In the Genocide fight, Red goes all out, summoning guardians and giving you a fight on par with Undyne the Undying! In the end, after you've beaten her, she attempts to give you the same crap Gerson said, about a hero eventually striking you down, and how not even you can cheat death. However, you laugh her off, being able to do so. Then, Flowey shows up to congratulate you on your victory.
- Behold... the No Damage Run against Omega Flowey.
- Even better. Toby didn't think it was possible.
- You think that's cool? How about No Damage Runs on all of the bosses? And the credits sequence too? You can see it here, but grab some popcorn. It'll be a while.
- Even better, Jaimers then kicked the game speed up to 1.5 (or 45 Frames Per Second) and ran the bosses on No Hit AGAIN. Including some extra enemies! Watch it here!
- Fan-made Chara Boss Fight. Interestingly, you play as Asriel rather than Frisk.
- It actually comes from the Dreemurr Reborn AU, in which Frisk finally found a timeline where they give their SOUL to Flowey so they can become Asriel again.
- Camila Suevas on YouTube made several awesome animations, which are worth a watch and tell their own story, Glitchtale, with the animation improving with each new video:
Sans: "hehe. aren't you missing something buddy?"(Chara's Perpetual Smile is wiped off their face when Sans steps aside, revealing the RESET menu behind him.)(...)
- First video: Megalomaniac, showing us the fight between a possessed Frisk and Sans. It is primarily a tearjerker though most of it, right through Frisk's Heroic Sacrifice of giving Sans their soul to use against Chara. Then Sans grabs it before Chara can, and things get epic! After crying over the earlier parts of the video, watching Chara get dunked on so massively is immensely satisfying.
- Second video: Yet Darker, the sansational battle, with Sans and Frisk vs. Dr. Gaster. Gaster tries to stabilize his return by stealing Frisk's soul and pretty much overpowers Sans in the process. Until Sans reminds Frisk of the Chara battle and manages to turn the tides using his power-up from their soul. The entire battle that follows is phenomenal. (as is the music)
- Third video: *Determination, in which Sans and Flowey team up together against Chara. This video also came with awesome fight music, that was actually mixed specifically for the animation. Also a villainous Crowning Moment of Awesome example from this one: Chara was able to kill the Amalgamates in the True Lab. In-game, you can't even hit them if you tried. Just shows how high their Killing Intent really is.
- Fourth video: Your Best Friend. In this one, every major character teams up against Chara as everyone realizes they have reached the Godzilla Threshold.
- Fifth video, and season finale of Glitchtale: Continue. Featuring Asriel, in his True Final Boss form, vs Chara. He ends it by taking a lesson from Frisk's book and saving her, even though her soul is too badly damaged to continue after her hatred (what her SOUL now represents) is purified. The video also sees Frisk DESTROY the RESET button.
- This fanmade Gaster battle. It apparently takes place at the end of a post-No Mercy Pacifist run, in which Gaster reforms himself with determination in an effort to stop Chara from possessing you and killing everyone. The fight has bullet hell that would make Sans jealous, including Gaster's "special attack" (using a giant Gaster Blaster to blow up the bullet-dodging box, opening up the entire screen to moving around and leading to him firing off some insane atacks) and a final, last-ditch Call Back to the Sans battle. The best part? Unlike a lot of theoretical Gaster battles, this one's actually playable!
- A few ambitious map makers for Team Fortress 2 decided to recreate the final battle of a neutral playthrough as a special fusion of control points, Arena, and Boss Fight maps that people made before Valve got into adding them. Of course, the original work in progress was really minimalistic, but when the model was finished, the map was changed so that the original placeholder broke apart and revealed that the new model was not only well-crafted and animated, but every bit as horrifyingly detailed as the original.
- Pinkielovania, a fan-animation by the doubleWbrothers. It has Twilight and Pinkie in the places of Chara and Sans respectively at the end of a Genocide run, and it features entirely new attack animations and dialogue, though it ends exactly like Chara and Sans fight eventually does, with Twilight cutting Pinkie down.
- Behold, Sanstale, where you play as Sans in a genocide route.
- The game's simple graphics make AMVs a real challenge. But YouTuber KUWA CHA animated a beautiful AMV sequence set to Ed Sheeran's "Photograph". It really captures the emotional range of the game, from its wistfulness to its ridiculous humor to its heartbreak.
- In the third part of the "Red Echos" arc of the Tumblr ask blog/spoilerrific post-True Pacifist webcomic Ask Frisk And Company, Sans fights Chara to the tune of "All Star" by Smash Mouth. With memes. It's every bit as amazing as you'd expect (Seizure warning. Seriously): part 1, part 2, part 3, part 4.
- Points have to go to how other people reacted to this.
- Look at Chara in the fourth part. Look at them while Sans was readying a trap card. They were gonna try and fight Sans, despite them knowing very well they are screwed at this point! There's a good reason they're still kicking around, and that's their determination.
- Frisk, being the pacifist that saw the horrors of their genocide run, still holds onto their nature as they tell Sans to spare Chara. And HE LISTENED TO THEM.
- However, what has to be the best one is how someone reacted after Chara kills Sans despite being spared. PAPYRUS. All I can say is, he reaction would make a disbelief Papyrus shocked in awe. Saying anymore would spoil it.
- Points have to go to how other people reacted to this.
- For those who might be disappointed by the fight against Mettaton NEO in a Genocide Run, here is a fanmade battle (unfortunely only an animation, so not playable) where he gets his chance to shine. It includes arm cannon, swords, flying, and, of course, lots of legs.
- A fandom example: At the beginning of Undertale fandom, it was generally accepted that the Fallen Human, Chara was the true villain of Undertale, influencing Frisk to embark on the Genocide Route in order to destroy everything. A small collection of Undertale fans theorized for a time that Chara may not actually be the game's villain, but instead is actually the game's narrator and Mission Control, but this was written off as a wild fan theory with no real evidence to prove otherwise. Then, in May of 2016, thefloweryfanclub (now renamed Determinators) published A CHARActer Analysis (WARNING: SPOILERS), a comprehensive guide to the game's in-game narration between each route using nothing but in-game screenshots: no philosophy, no psychology, very little commentary, only things you can see in-game. In a very short time, A CHARActer Analysis sparked a rapid change in the fandom's view of Chara, where they are now just as redeemable as the rest of the Undertale cast. Although the Narrator Chara theory still has its critics and awaits an official confirmation (though this archived Tweet from Toby seems to indirectly confirm it, theflowerfanclub/Determinators earned its Moment of Awesome for somehow finding a way to save Chara (among fans, at least).
- Getting Alan Oppenheimer, the original voice actor for Skeletor, to voice Papyrus.
- If you wanted to square off against Sans without having to leave a trail of dust to do so, you can finally do it!
- A group of fans are actually working on a full-length Undertale musical. With 41 songs!.
- Assuming this is the same one mentioned above, here's the playlist starting from the first song.
- This animation, showcasing Sans, Papyrus, and Gaster working together to build the CORE, and seemingly create Hotland in the process.
- Death By Glamour, an amazing fan animation of the Mettaton battle.
- Then there's Megalomania (separate from the animation above) showcasing a spectacular animation of Frisk's Genocide path.
- It was so amazing that it more than tripled the animator's subscriber count overnight! There are also hundreds of comments full of nothing but shining praise for the animator's skill.
- Home (amella Remix) - Animation: a beautiful animation made by Kuwacha (Zero) retracing Frisk's journey through the underworld, with a soothing medley of "Home", "His Theme" and "Undertale" made by amella playing in the background. The animation is top-notch, and is guaranteed to make you teary-eyed. And you will be caught off guard when the No Mercy route comes out of nowhere, complete with much somber music. The video, thanksfully, ends with the Pacifist ending.
- UnderRacer, a fangame that combines Undertale with Mario Kart. While a rather strange concept, the game controls well, has great spritework, a good soundtrack and has some nice nods to the fandom's many AUs.
- This what if animation of the Asgore fight in the Underfell AU has nothing but shades of Awesome, Heartwarming, and Tearjerker.
- Special mention goes to the creator of said animation. According to him, this was just practice with Adobe Flash and he doesn't blame anyone if the animation was bad. You know, for something that's considered practice, this animation was amazing from beginning to end.
- Details about the fight in question starting with the first phase. In this phase, Asgore tells Frisk of the atrocities he has committed hoping to provoke them to attack him out of rage. Throughout the whole thing, Frisk continues to refuse to fight despite having every reason to attack what was considered the most irredeemable villain in this AU. And this is all before the second phase decides to initiate. To not attack him would take a lot of guts to do so and Frisk does it easily as a child no less, its safe to say they would make Jesus Christ proud.
- The second phase is no slouch either. Here, Asgore pulls everything he can to make Frisk attack him to the point that he goes to attack the menu itself starting from the Item and eventually the Act button leaving only the Fight option. Does this deter the pacifistic Frisk into attacking him? Heck no it doesn't! What does he do in the particular situation? He presses the Fight button and deliberately misses his attack. Despite having removed the Mercy, Item, and Act button from the battle, Frisk still will not attack Asgore. It's the only time in any fight, animated or real where this comes into play and it is glorious to see it in action.
- The EpicTale AU is, naturally, made of this. It's kind of in the name.
- Special mention goes to Sans and Chara being so powerful, THEY BREAK REALITY BY FIGHTING.
- If you dodge Flowey's introductory shower of "friendliness pellets", he starts to get a little annoyed, and the second time, he resorts to shouting at you to run into the bull— er, friendliness pellets. After the third time, he throws his facade away and wonders if you just wanted to make him suffer. Even as he attempts to make it clear that he intends to kill you via undodgeable bullet ring, it can be satisfying to see through his ruse and piss him off by refusing to play along with him.
- If you decide to kill Dogaressa, Dogamy becomes depressed and hardly makes an effort to fight anymore. However, should you kill Dogamy first, Dogaressa snaps and becomes a much tougher enemy, hacking away with her axe.
- When Papyrus confronts you in a fight to the east of Snowdin Town, you finally get to see what he's capable of. He starts out with completely nonthreatening attacks that are incapable of hurting you if you're high enough in the box. "Guess he's as incompetent at fighting as he is at everything else", you think... and then he proceeds to turn you blue, forcing your soul to have "gravity" added to it and making those low attacks much harder to avoid. "Bonetrousle" kicks in. Game on.
- How does Papyrus learn your cell number? He calls them all sequentially until he gets to yours. He may be thick, but you've got to admire his determinati— I mean, perseverance.
- Papyrus is by far his most heroic on a No Mercy run, how? He doesn't attempt to fight you; instead, he confronts you with optimism, friendship, and mercy: even if it gets him cut down, he dies stating his belief that you can still do the right thing. Keep in mind that many people give up a No Mercy run at Papyrus, and you'll realize this is every bit as effective a deterrent as both Undyne and Sans, and unlike them, he doesn't even have to raise a violent finger towards you.
- When Undyne finally takes off her helmet and confronts you face-to-face.
- On the No Mercy Run:
Undyne: "My body...it feels like it's splitting apart. Like any instant...I'll scatter into a million pieces. But...deep, deep in my soul, there's a burning feeling I can't describe. A burning feeling that WON'T let me die. This isn't just about monsters anymore, is it? If you get past me, you'll...you'll destroy them all, won't you? Monsters...humans...everyone... Everyone's hopes. Everyone's dreams. Vanquished in an instant. But I WON'T let you do that. Right now, everyone in the world...I can feel their hearts beating as one. And we all have ONE goal. To defeat YOU. Human. No, WHATEVER you are. For the sake of the whole world...I, Undyne, will strike you down!"
- She comes in to intercept you at the last second when you attack the helpless Monster Kid, suffering a fatal blow in their place.
- Despite the fact that she's mortally wounded in a single hit like nearly every other monster you've fought up to this point, She channels the power of Determination to resurrect in a new form and give you hell. Yes, this girl went so anime that she channeled a power only humans are supposed to have.
- And then, there's what she says before the fight:
'*In a blinding flash of light, she turns into Undyne the Undying*
Undyne: "You're gonna have to try an little harder than THAT.
- Undyne becomes the only monster in the game from there on that you cannot defeat in one or two hits. Your attacks only take off small increments of her health, while every hit you receive has absolutely brutal effect.
- When (or if) you finally beat her, she's still so full of Determination that, unlike all other monsters, she begins to melt instead of simply turning to dust, like the Determination-infused Amalgamates. She dies with the widest grin you'll ever see on her, confident that Asgore will stop you and avenge her death.
- Even after you deplete Undyne's health completely on a Neutral run, she doesn't die yet. She somehow manages to keep going, even as her attacks slow and the music grows dreary, determined to not lose to you. In the end she melts like in the No Mercy route, screaming her refusal to die.
- Really... everything Undyne does is awesome. The woman is living anime. Even cooking is done with burning passion! Making friends has never been so intense! Shame about the house (it's still burning when you come back in the epilogue).
- Papyrus gets one when he manages a clever Batman Gambit to get Undyne to be friends with you, proving he can actually be pretty smart when he wants to be.
- If you rescue Monster Kid when he falls off the bridge, he puts himself between you and Undyne, his hero, and outright tells her that if she wants to hurt you, she'll have to go through him. This from a tiny kid who can't run without falling over and hero-worships Undyne. Kid's got some serious balls.
- Muffet's attack where she attempts to feed you to her pet, the spider-muffin-thing. It's one of the longest attack sequences in the game, and it's more dynamic than most, having its own build-up section.
- The boss fight at the end of the Core, Mettaton EX, is pretty cool, especially if you're trying to win non-lethally. The fight includes a "ratings" counter that you have to get over 10,000 (or 12,000 if you don't want to blow his limbs off), which is actually challenging as they drop fairly quickly.
- The ratings meter, especially as it increases, implies that everyone in the Underground is watching the battle. Ending the battle via the ratings meter (rather than killing the boss) has Mettaton commenting on his record ratings and a slew of viewers calling in to tell him how deeply his shows have moved them.
- You still have to survive the boss's attacks — although taking damage can also improve ratings, especially if you used the right ACT.
- Alternatively, another ACT has you boast that you won't be hit, which makes the ratings increase during the boss's turn as long as you stay untouched.
- Many types of items boost ratings when used, including changing your armor — and even using the Stick, if you kept it in your inventory.
- At one point the boss asks you to type something flattering, and reacts differently depending on what you write.
- Distinct from using the FIGHT option to deal damage, you can also attack the boss during some of their turns and cause his limbs to blow off.
- But most of all, why does this Glory Hound of a boss want so badly to defeat you? He knows that if you go on to fight Asgore and lose, Asgore will get the last SOUL needed to go to war against the humans — he wants to prevent that.
Final Area and Endings
- The beginning of the fight with Asgore, which the game has built up as the final obstacle of your entire journey. Then Asgore pulls out an Interface Screw of a degree that hadn't been seen in the game yet: destroying the MERCY button.
(A strange light fills the room.)(Twilight is shining through the barrier.)
- And then there's what comes next, especially for players who expected they were getting the best ending possible: everything about Photoshop Flowey, from the fight itself, to his trollface after loading his SAVE, to finally beating him.
- Special note goes to the six human SOULS uniting around you to give you the power and support you need to finally stand up to Photoshop (fan name Omega) Flowey, coming in with the track switch to "Finale", Flowey's defense is shattered and he DESPERATELY starts to throw everything he can at you. What seemed like a hopeless battle has turned. And after Flowey resets his SAVE and then tries and fails to reset it again, the SOULS reappear and attack Flowey themselves.
- Even though you've been forced to fight, the game still gives you the option to SPARE the boss. Flowey insists that the only way to end this for good is for you to kill him, even threatening to kill you and everyone you love if you let him go. If you persist despite having every reason to give in, he breaks down and flees, as you've shattered his worldview of "kill or be killed" which he's maintained from the start.
- Pretty much everything about the final confrontation of the Pacifist route.
- The build-up in which you get to see all of the friendships you've made, including gathering together all of the minor monster encounters, all to confront Flowey, despite it going badly.
- When the six big characters are first entrapped by Flowey's vines, notice Undyne. While the others appear stunned, she's fighting against the vines the entire time.
- While everyone is trapped and - judging by their expressions - in pain, they still protect you from Flowey's attacks. Even though Undyne is the only one fighting the vines, everyone is doing what they can to protect you who they have come to love so much.
- The build up right before the True Final Boss fight. After Flowey absorbs all of the monsters' SOULs from the Underground in a flash of light, the player is alone in a black void with a goat child. He then begins to introduce himself: cue turning around appearing as a Boss Monster like his parents, and the words ASRIEL DREEMURR appearing letter by letter in stylistic bold text.
- During the battle, the background shines with all the colors of the rainbow, the boss' attacks are extremely over-the-top and awesome, and he even calls them!
- And the background doesn't start doing that until the first crescendo in the boss theme.
- Dying in the fight against the boss yields this message: "But it refused." You can't die, as your SOUL simply mends itself together, no matter how much damage it takes.
- The final phase of the fight where the button to ACT becomes one to SAVE. You then confront the Lost Souls of the many friends you made throughout the game, absorbed by Asriel and fighting against you... but by reminding them of the times you have spent together, you are able to rescue them from hopelessness and get them back on your side.
- Also from the final boss fight: after the player saves all of Frisk's allies and tries to SAVE Asriel himself, the boss is reduced to firing a huge Wave Motion Gun while bawling Berserker Tears, begging Frisk to let him win, while Frisk's determination is so strong that they survive their HP going into the fractions, all the way down to 0.0000000001/20.
- The final boss is even more awesome if you're trying for a No Damage Run on top of True Pacifist. Because now Asriel is a legitimate challenge instead of a Foregone Conclusion, and his over-the-top attack patterns are almost as hard to avoid as Sans'.
- At the very end of the game after the True Final Boss, as you are free to travel and revisit characters, you discover that the biggest stealth badass of all was the one nobody expected: NAPSTABLOOK. Due to Asriel having learned your name with everyone's souls inside him, everyone now knows your name, except that one, single character. Why? When Flowey unleashed that flash of light that reached through all the underground, allowing him to absorb every monster, Napstablook saw the snails on their farm vanishing from their window and just shut the blinds. That's right: while Frisk was valiantly facing off against Asriel for the fate of the timeline, Napstablook was just chilling at home, same as always, no worse for wear!
- Playing through the No Mercy route will make you feel like a horrible person, but the final fight is awesome nonetheless in many ways. You'll definitely have to use some Villainous Valour of your own to win against this one, and it feels great when you do:
Sans: "it's a beautiful day outside. birds are singing, flowers are blooming... on days like these, kids like you... Should be burning in hell."*cue moment directly above*Sans: "huh. always wondered why people never use their strongest attack first."
- Absolutely everything about the fight is openly designed so that it's as rage-inducing as possible — starting with stupidly hard-to-dodge attack patterns that rack up immense damage from the smallest mistakes, and throwing in several Interface Screws and a number of fake-outs. Who's responsible for putting you through this hell? It's Sans, who finally decided to get serious. Turns out he's known all along that you're an "anomaly in the timespace continuum" with the power to reset the world, and he was hoping you might stop if he just became friends with you. But he also knows that this time is different, and if he doesn't stop you here, everything will end.
- The first thing they do, before the music starts, even before the battle menu comes up, is hit you with a rapid-fire series of attacks including giant laser volleys that are nearly impossible to dodge unless you know they're coming. After you finally manage to survive this, they comment that they "always wondered why people never use their strongest attack first." No other enemy does this. If you start the battle again, he'll interrupt his own monologue to sucker-punch you!
- There's also this little gem that Sans says before his fight:
- The above in itself is a CMOA for the boss themselves when you realize what the opening line in the dialogue box means: "You feel like you're going to have a bad time." At this point, the Fallen Child has fully assumed control of the character, and is known to be a horrific, soulless abomination that Was Once a Man, who thrives on the dust and blood of murder and even toying with hope of being spared, if you choose to be that sadistic. But Sans? Sans legitimately frightens this travesty of nature after the abrupt onslaught he unleashes so casually. He's the only character who scares the Fallen Child. For good reason.
- Who stopped Flowey every single time he got close to a genocide run or something like it, and forced him to reset the most? You guessed it.
- The boss shows their insane level of ability in an entirely dissimilar fashion to anything thus far: being the most Genre Savvy opponent you can face. They sidestep your attack every time, asking why they should just stand there and take it. When you finally overcome their best gauntlet of attacks, they unleash their special attack: nothing. Literally nothing. They're perfectly aware they can't beat you, and one blow from you will finish them, so they decide to do nothing, trapping you in their turn so you can't attack. There's only way you can win: dragging the borders of the attack zone with your SOUL so that you can reach the FIGHT command. But you still have to wait for the boss to fall asleep from exhaustion or else they'll reset your position. And even then, the boss evades your attack, so you have to break the rules further and attack twice in one turn to actually land the hit.
- Everything about the boss in this fight is badass. Their cool moves, their lack of care, their insanely complicated trolling, and their unwillingness to move an inch while firing these attacks at you demonstrate just how absurdly powerful they are.
- Perhaps the most amazing part is that this boss has, on paper, the worst stats in the game. 1 ATK, 1 DEF, 1 HP. "The easiest enemy," according to CHECK. But this enemy knows that tiny 1-damage ticks won't trigger your Mercy Invincibility. That means you're taking 1 damage per frame! Compare this to the Fallen Child's obsession with stats and power, and that by this point, you have items that give you maximum ATK and DEF. In this boss battle, your stat boosts are absolutely useless. Considering you are about to finish a complete monster genocide, you feel "your sins crawling on your back", and being hit incurs residual damage in the form of poisonous Karma, you might suddenly realize that "No Mercy" means no mercy for you, either.
- Again, playing the No Mercy run will make you feel awful. But after dying literally dozens of times to this enemy, nothing will feel sweeter than finally killing him off. One of the more awesome moments, simply because of how unbelievably difficult it is.
- Sans makes fun of the player every time they die during his fight and come back to try him again. Kill him once and restart just to fight him again?
Sans: that expression you're wearing...Sans: ...
- There are several bosses that can change the color of your SOUL. But they all have a certain trick. Papyrus sends you through a whole turn's worth of blue bones, Undyne strikes you with her spear, Muffet pours tea on you, and during the Mettaton fight, you use a phone program that Alphys wrote. But there's one boss that can manipulate your SOUL at will, changing you between blue and red in the middle of a turn. Sans.
- After finally taking out the above monstrosity, you get a rather twisted moment yourself during the confrontation against Asgore. Just before he is cut down, Asgore mentions he was warned about you by a certain flower. After killing him, a desperate Flowey strikes the final blow and begins begging you for mercy. You're so crazy, you manage to put fear back into a deranged, sociopathic abomination.
- While most players tend to focus on the fact that you can choose (in vain) not to erase the world in the end, it's entirely possible to go along with Chara's suggestion, even if you're fully aware that doing so might involve them "killing" you (implied by the slashing animation). You can choose to be someone filled with determination to destroy everything, up to and including yourself, proving that sometimes, the cruelest and most destructive people are those who, unlike Flowey, don't fear death.
