Flipped Destiny

Flipped Destiny is a more serious conceptually different AU which is partially based on fan interpretations of Underfell and partially based on a site I found that inverted the Megalovania MIDI. It was originally intended to turn characters into their exact opposites, but then I realized that was dumb and changed it to having certain traits of the characters completely inverted, and on the inside they do have traces of their original selves.

Characters

 * Frisk is exactly the same, as the opposite of nothing is nothing
 * Flowey believes he's trying to kill you for just reasons and it's all for the sake of monsters
 * Toriel really just doesn't give a shit
 * Napstablook is generally chill and happy with what's going on
 * Sans is openly depressed and internally optimistic, but overall really overworked and scared of his brother
 * Papyrus is kind of a dick, he doesn't really do anything except yell at Sans to do his stuff, just a bad person overall
 * Undyne is cheery and doesn't want to hurt anyone, so she's not okay with the fact she has to kick your ass and she's more soft overall
 * Alphys is more deranged, mad scientist-y, that kinda thing, so she's basically just a supervillain or something
 * Mettaton is really modest and doesn't do well in social situations, it was Napstablook who got him to go out and be the star he secretly wished he was
 * Asgore has lost his cheery disposition after having killed 6 humans and has taken a more angry madness kinda guy route
 * Asriel as a kid was a brat while he was alive, but when you see him in the True Pacifist Ending he's reformed like his more original self, though as the Hyperdeath form he, like Flowey, is fighting for what he believes is the right thing to do
 * Chara was a nice kid who got along well with everyone, they even got Asriel to chill a bit
