@Impel:
To be fair, he attacked her first, and she is doing it for revenge, yes, but she's not making it really obnoxious that she's doing it for revenge, not even really mentioning Colonello the whole fight.

She's the one who wanted to fight Gingerbread. If that isn't some sort of desperate cry for Colonello revenge, then I don't know what is.
@Sandai:
I never said you disliking her as a character mattered to me I just wanted to know why you felt that way, also I don't think those reasons are valid enough.
Wait….what?
Since you appear to know what qualifies an excellent reason(s) to hate a character please explain your "valid" reasoning. Otherwise, you seem to just be talking out of your ass. There are other people who don't like a character for stupid things, like character design.
I don't like a character. Fuck. It's not the first time it's happened.
