AU: Basically Frisk lived in the underground and grew up together with Sans(Also Frisk is a girl in my AU) you get to choose your character name, gender, what your character looks like, and E.T.C, 1-4 can play together, and discover many things. (It's the friendship kind of Frans, don't worry, they're really good friends and will support each other until the very end). How Frisk Fell: Basically her parents threw her in there with her sister (Chara) who hates monsters down to the underground to spy on the monsters. Only thing is, the plan was for Chara to oof (Frisk in order to get out) all the monsters, but in the end they realized someone already oofed all the monsters and was currently fighting Sans, and in the the end the person got oofed and reseted. So everything went into a internal loop when something happened which caused the monsters to go back to normal and the person (Player) not being able to reset anymore. That's when Sans and Frisk became friends trying to figure out who the person was. Meanwhile, Chara went out to try to find the person and team up with her. Then another character comes, named Glitch (that's his code name) and finds Player when Chara also finds Player at the same time, the problem was so bad that one member of the Star sanses and one of the members of the bad sanses were involved too.
