Ratboy is a prospective member of SAMCRO who is introduced in season four and often appears along with fellow prospects Filthy Phil and Miles. As prospects they are assigned menial or low level tasks, including guarding a shipment that is very important to the club. When something goes amiss, Ratboy and Phil are made to answer, even though they are innocent. Ratboy has the good sense to be afraid of Happy, the club's most violent member.
