(Small Undertale spoilers for the end of the genocide route)
Intro:
Echo BF teleports into the world of Undertale at the very end of a genocide route, stumbling upon Chara attempting to kill the player. Although she succeeds in the kill, the game is kept alive, in it's half-crashed state, because BF is still alive, despite his Undertale soul being killed also. In this state, where Undertale's battle physics aren't quite up to code anymore, Chara wants to increase their power and erase the world and BF just wants another challenge, they battle.

(The game being broken is my excuse for the real knife not doing max dmg, blue attacks not being avoidable by standing still, etc, so I can at least have an entertaining fight, instead of Chara winning in an instant from their first hit)
