Dorkus is a grumbly old cloak-wearing creep who is bound and determined to put an end to Sheen Estevez. Why's he so mean? Because before Sheen showed up, this evil schemer used to be the Emperor's right-hand man. Now he has been unseated by a spazzy space cadet who can't even pass the 4th grade, much less rule a planet. But even though Dorkus has good reason to be irritated with Sheen, there is no excuse for sending him into the clutches of terrible monsters, week after week. And for this crime, Dorkus will most certainly pay.
Sheen crash lands Jimmy Neutron's 'borrowed' rocket on Zeenu, has tons of misguided adventures and deals with the planet's weird creatures and a stranded NASA-trained, talking chimp who joins Sheen on the quest to get home.
