Sheen is not the brightest bulb on the Christmas tree, but what he lacks in smarts he more than makes up for with his appetite. Sheen is obsessed with the Ultra Lord action hero. He collects all the Ultra Lord action figures, cards, and quotes him daily. Sheen is 13 years old (he was held back a few times).
Sheen is a turbocharged, hyperactive child with an attention span of 0.4 seconds. His best friend back home is boy genius Jimmy Neutron. He's got a passion for life, TV, guacamole, and a superhero called Ultra Lord. He isn't the best student, but what he lacks in common sense and focus, he makes up for in burning curiosity and loads of energy. One day, disobeying Jimmy's specific instructions ("Sheen, Do Not Touch This Rocket!"), Sheen touches a rocket and goes flying into deep space. He lands on a strange planet called Zeenu, where the grand leader thinks that Sheen is destined to bring peace, prosperity, and eternal joy. After the Emperor promotes Sheen to be his number one Royal Advisor, Sheen gets to do virtually whatever he likes, such as battling man-eating creatures and throwing wild parties. Even when the evil villain Dorkus tries to destroy him, Sheen's crazy ways almost always save the day. He doesn't seem at all worried about whether he'll get back to Earth or not.
