Shawn is Ron and Hana's seven year old cousin. He appears as a troublemaker who torments Ron at family functions. (Ron still has not gotten over the time Shawn poured gravy down his pants.) Shawn owns a pet lizard who apparently has made numerous attempts to eat Rufus. Ron's complaints about his cousin have mostly been ignored because Shawn is younger. Ron is unable to ditch him until Kim agrees to be his date at his cousin Reuben's wedding, thus sparing him from having to sit at "the kid's table". Ron also resorts to using the Attitudinator device to make Shawn less annoying. Shawn's last name is never mentioned though it is presumed to be "Stoppable". He is voiced by Tara Strong.
