Repo!Fell

so this is a huge info dump for an idea that entered my brain and refused to leave thereafter and now i am enslaved to bring it to life, if only via this babble

Repo! The Genetic Opera / Fell-Adjacent Undertale AU Full breakdown below the cut, this will be a huge post but I might use it as a Masterpost if this thing ever takes off with more than one or two posts. Tag will be Repo!Fell because that works I guess.

CONTENT WARNING: Due to the generally dark nature of Repo’s lore, this thing will get pretty gritty. Specifically, there are mentions of; Drug Addiction, Drug Use, Plastic Surgery Addiction, Extortion, Main Character Death, General Death and Suffering, Drug Epidemic Insinuations, Body Horror

Changes from the canon otherwise;

Sans and Pap are playing a married couple, according to the REPO canon- this is retconned bc this is not that kind of AU. The lost relationship here is the deep-rooted brother bond that we see in every instance of Undertale AUs. 

Sans and Frisk have an uncle/niece relationship, with Pap having played the role of 'adoptive father' for Frisk previously. 

Frisk is about 10 when they arrive and is the REPO-canon 17 during the events of the 'opera'.

The same can be said for the Asgore as Rotti and Pap as Marni dynamic- the 'unrequainted obsessive love' situation is replaced with Asgore having wanted Papyrus as his Hand. Frustrated by Sans keeping Pap from agreeing to this role and getting in the way, this obsession only becomes worse when Pap dies and leaves him with no probable hand.

Except, well, there's the judge (good doctor?) Sans (Nate) and gee, his powers sure do come in handy in this fell-adjacent version of the underground! He puts that to good use via blackmail- Sans thinks he's at fault for the circumstances of Pap's death and while it's actually Asgore behind it, Asgore uses this belief to control Sans.

Frisk is in a stalled pacifist run- halted by Pap's death but seemingly unaware of resets. This is their very first run and so far they haven't died. Flowey doesn't leave the ruins with Frisk in this fell-adjacent setting, one of the biggest differences from the original fell canon. Forced to live most of her life inside the skelehouse after Pap's death because Sans is tired and stressed enough as it is with his double life and trying to keep his promise to Pap that he'd protect this kid.

Papyrus is the one who takes a liking to Frisk and literally adopts the kid when they wander out of the ruins, a mess and half dead. He literally dies protecting them and forces Sans to make the fateful promise to protect the kid and keep them alive. Dies off screen, Asgore 'finds' him and claims it to be Sans' fault to divert when Sans finds him with the evidence. "You should have been there to protect him! You're his older brother, where were you!?"

Toriel is blackmailed / extorted into being an active Queen and Asgore's wife against her will and this removes her tutorial role entirely- she is instead fully immersed in the role of Mag. She sees her dead child Chara in Frisk instead of having any true relation to the brothers. She was once friends with Sans through the door as per the usual canon, but her returning to being Queen after some time being the crazy ruins lady ended that friendship prematurely.

Asgore as Rotti is rich with souls and level. He is dying, as per the REPO canon, and doesn't want to leave his wealth and kingdom to any of his various subleaders- Undyne, who leads the Guard/Military as the General; Alphys, royal scientist, as Pavi (who craves praise vicariously through her tech, especially Mettaton) and Mettaton, whose inhabitance of the robotic body is only managed with unhealthy and destructive DT Dose / Upgrade cycles, leading to further and further instability but dependence- as per Amber Sweet.
