Warning: Unmarked Undertale Spoilers below.
After receiving a letter from their estranged cousin, Napstablook races against the clock to see Mettaton one last time before the genocidal human knocks on his door, only to, in a strange turn of events, wind up gaining corporeality in their dead cousins body.
Now, in a body shattered by bullets, they are left to deal with the bitter aftermath of the humans massacre and the changes that come with it...luckily, theyre not in this alone.
Entity NEO provides examples of:
- Accidental Murder: In chapter 12, Napstablook accidentally pushes the fallen human to his death after tripping on their ankle.
- Arm Cannon: Mettatons NEO form has one. Unlike in game, it actually sees use in the comic...albeit twice. And not in the situation youd expect.
- Ascended Extra: Originally a minor, if memorable character in-game, Napstablook basically becomes a main protagonist in-comic.
- Back from the Dead: Mettaton briefly revives to kick the second fallen humans arse, when his cousin straight up blacks out from the trauma.
- Batter Up!!: The second fallen human uses a baseball bat as her weapon of choice.
- Big Brother Instinct: Despite not being brothers, Mettaton is this towards Napstablook, even going as far as to resurrect briefly just to get his cousin out of harms way.
- Break the Cutie: Oh boy. After accidentally becoming corporeal in their cousins dead body, being shot multiple times by the person who murdered their cousin, unintentionally killing an innocent human, and having the aforementioned point come back to send them into a Heroic BSoD, on top of dealing with being abandoned by their late cousin, its pretty safe to say that Napstablook definitely isnt having a good time.
- Downer Beginning: The story starts during the humans No Mercy route. By the end of chapter 1, Mettatons dead, Napstablook accidentally winds up corporeal in his corpse after experiencing extreme levels of fear from being shot multiple times by the Fallen Human, and while the evacuation is carried out in time, Asgore also dies at the hands of the human later on, forcing Alphys to take up the mantle of Queen.
- Dramatic Irony: Napstablook comes to the conclusion that Sans saved them from the second fallen human, when their real savior was in fact Mettaton, momentarily reviving to prevent his cousin from falling to their death. Made worse by them later calling him out for not being there for them.
- Exotic Eye Designs: Occasionally, Napstablooks eyes are drawn with heart-shaped pupils. If it breaks, you know shits hit the fan for them.
- Fake Arm Disarm: The second fallen human knocks off Napstablooks left arm with a baseball bat as she gives them a No-Holds-Barred Beatdown.
- Pink dust appears in chapter 13, after Alphys takes apart Napstablooks body for repairs. Thats Mettatons dust, and it vaguely foreshadows his brief return nine chapters later.
- The first four pages of chapter 22 just about sum up the events of the entire chapter.
- For Want of a Nail: The entire premise of the comic is that Mettaton sends a last minute letter to his cousin right before the human comes to town, which sets the plot rolling.
- Grew a Spine: Alphys starts off timid and insecure over her failures, but she eventually adapts to the responsibilities that come with being crowned queen of the Underground.
- Heroic BSoD: Napstablook notably has one in chapter 22, on the cusp of being beaten to death.
- Hidden Eyes: Very common, particularly during emotional moments.
- High Heel Hurt: Unfortunately for Napstablook, high heels are permanent fixtures on their new body. Needless to say, they end up tripping a lot.
- Mood Whiplash: The story starts off dark and depressing, gradually lightens up somewhat, then immediately plummets back into angst territory again. And thats just the first twelve chapters.
- On a smaller scale, this trope is usually invoked due to the art style.
- A Molten Date with Death: The second fallen human meets her end by being blasted into one of Hotlands lava pits.
- Morphic Resonance: Downplayed. In-comic, Napstablooks core glows blue when theyre in the body, as opposed to it glowing pink when Mettaton takes the wheel in chapter 22.
- Not Afraid to Die: Mettaton chooses to stay behind and confront the human in order to buy time for the evacuation, knowing full well such a choice might cost him his life. It does, and he goes out in one shot anyway.
- No-Holds-Barred Beatdown: The second fallen human delivers one hell of a beatdown to Napstablook, after they regretfully admit to accidentally killing her boyfriend ala Railing Kill.
- Not Too Dead to Save the Day: See Back from the Dead.
- Posthumous Character: While Mettaton dies early on in chapter 1, he still leaves a lasting impact on the plot, most notably Napstablook. For the rest of the story, much of his Hidden Depths are revealed through flashbacks as Napstablook comes to terms with his passing and their own conflicting emotions regarding him.
- Shout-Out: Sans briefly demonstrates his knowledge of pop culture.
- Railing Kill: Because even a railing cant stop them from tripping and accidentally pushing the first fallen human to his death.
- These Hands Have Killed: Albeit unintentionally.
- Transformation Sequence:
- Played straight the first time when Napstablook switches from NEO to EX, complete with legs.
- Downplayed with the next two form switches in chapter 22.
- Unable to Cry: One side effect of being stuck in their cousins former body is the inability to shed tears. At all. Napstablook doesnt take well to this.
- Violently Protective Girlfriend: The second fallen human willingly ventures into the Underground and beats up anyone in her way for the sake of finding her missing boyfriend. She doesnt take Napstablooks regretful admission of Accidental Murder well, to say the least.
