Well, being an anime dumbest, here's a few I suppose.
Princess Komi
Simple, lovable character who's treated like an utterly adorable princess despite not being royal, and having no social skills whatsoever. Is also responsible for this:
Princess Melty
A reference to the Shield Hero Princess of the same name, she's pretty royal, and capable as well. Just an awesome character overall.
Princess Lum
Anyone who's seen Urusei Yatsura loves Lum, despite the fact she's in love with a total jerkass. She's pretty great herself and is a classic early 80's anime character.
So yeah, those are some... suggestions.
