Trigger Girl

A character in a piece of media who enters into the story as one of the most powerful, charismatic, and almost always morally-correct characters. If they have any character flaws, it will be because they "care too much" or are "hot-headed" despite winning every fight they have. Unlike a Mary Sue, the story does not revolve around the Trigger Girl and the plot will resolve around things a Trigger Girl can't beat into submission (e.g. solving a mystery, fixing a broken family, being a side character)

"But that's a Gainax show!"
"Doesn't matter, Yoko is still a trigger girl. So is Kamina!"
