Quinze
Quinze was a total asshole. The scientists screwed him over when they changed his plans during Operation Meteor. Towards the end of the show, he became the leader of White Fang, and was completely responsible for seeking Milliardo Peacecraft as their sovereign. He turned into Milliardo's Number Two, his right-hand man, the VP...you know what I mean. He took commands from Milliardo Peacecraft, and, although he made snide comments under his breath about the situation at hand, he never wavered in his reluctant submission.

One has to wonder how he ever led White Fang in the first place.

He also hesitated in putting words into action when Dorothy Catalonia started giving out the orders. (One can safely assume that he's at least 10% sexist. Maybe Wufei's attitude is rubbing off of him)

Quinze was sorta like  a schizo, his personalities swaying from absolute cowardice to something that could ALMOST be compared to bravery.
