Web Animation / Underfell (RynoGG)

Warning. This page contains unmarked spoilers for Undertale. You Have Been Warned.

"So let me get this straight...
You're a kid...
A kid that fell down from the surface...
And you managed to calm a beast like her...
By being patient.
...
I don't think this world is kill or be killed anymore.
And I think we can get out of this hellhole pretty easily."

Underfell, officially titled GG!Underfell is RynoGG's interpretation of the Underfell AU. Contrary to appearance, it isn't a Game Mod, but rather an animation/machinima.

Similar to most other interpretations of the AU, this version of Underfell follows the story of Frisk and Flowey as they traverse through a world of monsters who believe that the meaning of the world is to "killed or be killed" thanks to Asgore. Unlike most interpretations, this one aims to be be more accurate to Undertale's lore, featuring characters with similar personalities to their original counterparts.

This Underfell interpretation was included as the third section of Deltatraveler as of its version 3.0.0 update, which expands a bit on Sans's history.

As of now, six episodes have been released. The first one can be seen here.

This version of Underfell contains examples of:

• Action Dress Rip: Toriel's robes appear tattered, further backing up the fact that she had been Driven to Madness. Once Frisk spares her and leaves the Ruins, she's wearing fresh new robes in the title screen.
• Adaptational Context Change:
  • Flowey still greets Frisk when they come to the underground, however, it is bit different. Instead of pretending to be nice and tricking them into running into his bullets, here, Flowey doesn't even bother fighting them because of his injuries and bluntly tells them that coming down was a big mistake. He still of course brings up his iconic philosophy of KILL or BE KILLED, except he wasn't the one who came up with it.
  • The "# left" text appears every time a SAVE point is interacted with, except instead of counting the remaining kills, it's tracking how many encounters there are left to end peacefully by pacifying the enemies.
• Adaptational Nice Guy: While Flowey initially still holds the "kill or be killed" belief, he's much more reluctant in doing so, only wishing that Frisk would kill monsters for the sake of keeping themselves safe. When he joins the party, he'll assist Frisk in battle. While he does initially get irritated at Frisk for sparing monsters, he's only angry with them that they might encounter a monster who won't let them spare them. Once Frisk manages to spare Toriel, who Flowey believed would be impossible to tame, he completely drops the "kill or be killed" ideology and from there on gives Frisk advice on how to spare certain enemies when "Check" is used. He also seems to be capable of having some degree of compassion, having described Chilldrake's speech as emotional.
• Adaptational Jerkass: This version of Underfell shows a version of Sans who practically lost all hope long ago. Sans is quick to ambush Frisk and nearly kills them in seconds if it hadn't been for Papyrus, who believes that killing is an "art". Sans doesn't seem very nice to Papyrus either and it's implied that he's psychologically manipulating him into doing what he's doing. Sans will also resume trying to kill Frisk when they've found all the ladder pieces when Papyrus isn't around.
• Adaptational Villainy: Sans, full stop. He's been said to have harassed the monsters living in Snowdin Town, believes in the "kill or be killed" idea, and is implied to have been corrupting Papyrus into becoming malicious. In heavy contrast to his canon counterpart, who encourages Frisk to try to get through the Underground without killing anyone, this Sans believes that it's foolish for them to believe that they can spare everyone. Some of his dialogue in Deltatraveler reveals the extent which he's gone: he's already killed 243 people.
• Adaptational Wimp:
  • Flowey doesn't appear to have the same powers that he had in the original timeline, forcing him to be more careful.
  • Sure, Sans' bullets deal 5 damage, but his attacks are mostly easier to dodge, he doesn't use karma, and he doesn't do damage for every frame, though the invincibility frames are still significantly lower when he attacks, meaning that he can still very quickly kill Frisk if they're not careful.
• Adaptation Deviation: In the first section, the "game" has a new story, but the gameplay is mainly the same. From the Snowdin section, the "game" further departs from the original game's storyline by completely changing character interactions, setting the protagonist on a different path, including a new mini-arc, having new enemy encounters and hinting at an enemy that has not at all been present in the original Undertale.
• Affably Evil: Papyrus fits this to a T. Sure, he makes it very clear to Frisk that he does intend to kill them, but he's relatively polite about it and believes it has to be done fairly and correctly, through traps as opposed to Sans' more direct and ruthless attempts. In fact, he apologizes to Frisk for Sans being too aggressive.
• Anti-Frustration Features: Frisk actually needs to solve the tile puzzle thanks to Papyrus resetting it when it gives a straight path, but because the directions are hard to remember, he gives them the liberty of knowing what flavor they currently are.
• Ain't Too Proud to Beg: Just as Flowey tries to attack Frisk, he finds himself unable to do so and begs them not to kill him as he claims to not deserve death. Fortunately, Frisk spares him and he is very much grateful for it.
• Anger Born of Worry: Flowey is very much frustrated with Frisk constantly sparing the various monsters they come across, as he insists that kindness won't be enough to stop them from trying to kill them.
• Art Evolution: Frisk and Flowey's sideways facing sprite was updated in episode 5 to make Flowey's face visible to the viewer. In episode 6 onwards, thanks to using Deltatraveler's engine Flowey sometimes appears in the battle textbox and Frisk's HP is displayed if they take damage in the overworld.
• Ax-Crazy: Toriel while she was Driven to Madness, having killed several monsters in the past and at one point, a human, whose remains can be seen in their "bedroom".
• Beat the Curse Out of Him: All of the "Feraldrakes" in the forest (minus the Chilldrake) need to be attacked at least once in order to cure them of their "Malicious" status before they can be spared.
• Because You Were Nice to Me: This is the main reason why Frisk can help ease the various residents of the underground. It is also the reason why Flowey is tagging along with them, as he was mysteriously wounded with no further explanation.
• Be Careful What You Wish For: The Player modified the files of Undertale to have a "evil mode" so it would provide a different challenge. However, upon seeing Toriel for the first time, they are having second thoughts about their decision.
  The Player: "the fuck is going on with this game"?
• Brain Bleach: When Frisk and Flowey enters a bedroom where a trail of blood led to, they were horrified. The narration gives a rather vivid description of the mess: a human skeleton, dried blood all over the place, and organs. It's so horrifying that Frisk takes one hit point of damage from just seeing it.
• Color-Coded for Your Convenience: "Malicious" enemies are blood red. Oddly, Flowey's friendliness pellets are still white despite healing Frisk upon contact. This is later changed in episode 6 in which they are now green.
• Comically Missing the Point: When one of the Drakes says that they wanted to eat the ladder piece, Flowey said they shouldn't, especially since it's made of wood. The Drake then realizes that there are trees all around him, so he could eat them instead.
• Crapsack World: This version of the Underground is awful to live in. Most monsters became violent and/or rude, and those who haven't end up suffering from this. Some have developed heavy trust issues, a notable example being Lesser Dog, who cowers in fear at the sight of anyone it sees.
• Darker and Edgier: As per usual for Underfell, the underground of this world is very much dark. However, there are far less warm and dark edges to be seen and are instead replaced with more realistic horrors that are discussed quite frequently. This includes insanity, depression, abuse, suicide, and of course, murder.
• Death Glare: Toriel gives one to Flowey when she sees him trying to talk to Frisk.
• Do Wrong, Right: Papyrus believes that Frisk should be killed through a proper trap, not just directly butchered like Sans would prefer to.
• The Dreaded: When Flowey realizes that Toriel has seen him, he is so terrified that he is scared stiff. And it turns out, he has a good reason to be afraid of her. She is a vicious killer who will slaughter anyone who trespasses in the ruins. And what is worse, she is very much willing to kill the humans that fall down. The only known one she managed to kill ended up becoming her meal.
• Driven to Madness: Many years after Asgore first installed the "kill or be killed" rule, the monsters eventually turned "Malicious." To spare them, Frisk needs to cure them of their "Malicious" status, then fulfill any other spare conditions they may require before sparing them.
• Driven to Suicide: The Nice Cream Guy apparently killed himself after deciding that there's no point in Nice Cream in such a cruel world.
• Enemy Scan: Flowey provides the "Check" ability for Frisk. In addition to the usual information, he also provides the enemy's exact HP, and if he knows how, he'll tell Frisk the optimal strategy needed to spare the enemy.
• Foreshadowing: When the player opens the game's properties, they type in a string of words at the end of the target prompt. What do these words say? "evilmode".
• Freeze-Frame Bonus: If you're paying attention, in battle, you can see Flowey's sprite in the "Items" portrait emoting based on the situation.
• How Is That Even Possible?: Flowey's reaction to Frisk successfully taming Toriel, briefly being unsure if he's dreaming or not.
• Insistent Terminology: Sans keeps calling Papyrus "boss" despite Papyrus constantly telling him that he's not. Of course, given the implied manipulation, Papyrus is most definitely not the one truly in charge.
• My God, What Have I Done?: When Toriel is cured of her Malicious status, she expresses horror over coming close to killing another human child as well as the countless numbers of monsters she had killed in the past.
• Nightmare Face: Several of the boss characters that Frisk encounters have horrifying expressions on their faces in their dialogue potraits and/or their battle sprites. It doesn't help that their battle sprites are blood red.
• Not a Morning Person: Frisk once again finds Napstablook sleeping in the middle of the Ruins once again, except their eyes are shut, and seem to be genuinely asleep. However, once Frisk tries to move them, they go from white to black and attack them.
• Ominous Visual Glitch: When the player loads up the exposition cutscene, it briefly glitches, before returning back to normal. This is a subtle hint that the world you are about to enter is very different. It also happens again when meeting Flowey as his Leitmotif distorts and the screen briefly flashes white, with the theme now slowed and revealing a now wounded Flowey.
• Red and Black and Evil All Over: The malicious monsters in battle are this. Instead of being white and black, they are red and black.
  • When Napstablook is ticked off, he can put on his Game Face and go from a white Bedsheet Ghost to a black one with red highlights. However, he drops the mask once he feels regret for attacking Frisk, who was trying to be nice to them.
• The Resistance: There are still a few monsters who haven't adopted the "kill or be killed" ideal and had isolated themselves from the malicious monsters.
• Retcon: As of episode 6, a few changes have been made such as toning down Ice Cap's swears, giving the snowdrakes the Deltatraveler version of their homing attack, and making Flowey's healing bullets green.
• Shout-Out: The Lesser Dog fight uses a slowed down version of "A Dogmatic Encounter", which originates from the Undertale: Bits and Pieces mod.
• Support Party Member: Flowey doesn't use any attacks, but he helps Frisk out by throwing genuine friendliness pellets to heal them at the end of every turn when they've taken damage. Using Check has him give advice on how to spare the monster.
• Token Good Teammate: Downplayed. Papyrus is still trying to kill Frisk for their SOUL, but he's against killing them the "easy way" (which Sans prefers) and is implied to be psychologically manipulated by Sans into acting the way he is, something which Flowey suspects.
  • Played straight with Napstablook as he only attacked Frisk because they disturbed his slumber, and once they start to cheer him up, he stops fighting them and apologizes for attacking them. He also reveals that the reason why he was in Ruins in the first place was to get away from all the rude monsters that were everywhere else, but he is glad to find someone who is genuinely a nice person.
• Uncleanliness Is Next to Ungodliness: One of the biggest hints that this Toriel isn't as civilized as the one we are used to is the fact that her dress is not only dirty but also tattered. It's almost as if had been battle-damaged from several fights...
• Unexplained Recovery: When Flowey first appears to Frisk, he looks totally battered, having his face and petals partially torn and with a melancholy expression. When meeting Flowey later on when he tells Frisk to fight the dummy, his face is back to normal (though as of episode 5's Art Evolution, his petals remain damaged).
• Violation of Common Sense: The best way to calm down plenty of malicious enemies usually ends up being what appears to be the opposite of what you normally would want to do. For instance, Loox becomes sparable if you pick on it (it's glad to see that you aren't afraid of it) and Snowdrake requires you to heckle it once before you can react to its joke like normal. Also, the concept of approaching a malicious enemy with kindness seems rather absurd until you realize that patience is key.
• What Is This Thing You Call "Love"?: When Frisk compliments a malicious Froggit that attacks them, it feels a strange feeling it was unable to describe and loses the will to fight, allowing Frisk to spare them and walk away unscathed.
• Why Don't You Just Shoot Him?: Sans would rather just kill Frisk directly and instantly, but Papyrus insists they need to do it the "right" way, through death traps and trickery.
• Wistful Amnesia: While Toriel is Malicious, she still makes the phone call to Frisk asking what their preference for pie flavor was. Judging by the tone, a viewer may be brought to believe that this is an attempt by Toriel to poison Frisk, but when she is cured of her Maliciousness, she remembers about the pie and reassures Frisk that she did not poison the pie and she's not exactly sure why she made it even while being Malicious, implying that this trope was in effect.
• Would Hurt a Child: As expected, many of the monsters attack Frisk without hesitation. The only difference? They are now doing so with malicious intent.
