"Shawn" is Ron's 7-year-old cousin. He has the personality of a troublemaker, and has apparently been a constant source of torment for Ron at family functions. (Ron still hasn't forgotten the time Shawn poured gravy down his pants.) He owns a pet lizard who apparently has made numerous attempts to eat Rufus. Unfortunately, since Shawn is still a little kid, Ron's complaints at his behavior have been pretty much ignored. Ron wasn't able to ditch him until Kim agreed to be Ron's date at his cousin Reuben's wedding, thus sparing Ron from having to sit at, according to Ron, "the kid's table". Ron also resorted to using the Attitudinator device to make Shawn less annoying. Shawn's last name is never given though it is presumed to be "Stoppable."
Fun Fact: Shawn is voiced by the same person as Britina!
