Which prim, proper, and generally humorless Weasley son is the black sheep of the family?
Answer Percy
Percy's always been a little more serious than the rest of the Weasley clan, but the stakes are raised when he breaks with his family and sides with the Ministry of Magic in The Order of the Phoenix. Don't worry; he comes back into the fold in The Deathly Hallows and fights the Death Eaters with the other members of the Weasley family.
