Ron Weasley

Ron Weasley is an adorbale side-kick to Harry Potter, who eventually gets with Hermione. Go figure. Though to be fair, Harry does get with his sister.

Anyway, Ron helps the gang out by using his above-average but not spectacular magical abilities to lift up things, move things around, and throw people out of windows. He also can't pronounce Leviosa, apperently.

He also hates Snape, and anyone with more money than him. So pretty much the entire upper class of Hogwarts.
