Write this 500 times, self

I will not write crossovers between A:TLA and Disgaea. Especially not crossovers where Toph and Azula run into someone who was designed by her father to be a weapon and then was abandoned by the dad and now wants to be a formidable foe to any hero that stops by.* Who is a moth-serpent-human and would be perfect for my animal play square for kink bingo.

*By which I mean, the best final boss ever. This is why I can't get Disgaea crossovers with A:TLA to work: all the characters know they're in a video game. And because A:TLA's villain progression is very video game-like, I keep thinking there must be A Way.
