Here are some concepts. Tell me if you guys have any preferences.

(Elemental Knight) Quick, quick thinking, quick reacting, quick to judgement, quick tongue. Has a tendency to get in over his head and get into stupid situations without thinking. Rotten luck. The flunky of the class.

(Holy Knight) gooey sweet, perfect, caring, super nice. This is enough to make an oompa-loompa enter into a diabetic coma.

(Demonic) Happy-go-lucky kinda guy with demonic powers... what's so strange about that?

(Blook Knight) big, fat, ugly old sinner, "My eyes! My eyes!" "Ah, that's right, I can feel your suffering now!"

(Warden) Negative downer, scrawney and thuroughly sucky at the whole knight thing. He is best at getting his butt handed to him, but he can endure so much that he exhausts his opponents.
