Dorkus Aurelius is the main antagonist of Planet Sheen. He's mad that Sheen broke his house, and constantly tries to destroy Sheen, like when he sent the guards to take sheen to the palace of pain. He has a floating one eyed head creature with bat wings and two little legs named Pinter who constantly praises Dorkus. In The Boy Next Dorkus, Dorkus's house was finally rebuilt until it blew up again, due to Sheen accidentally tossing a cluster bomb into it.
He appears to be green with a grim-reaper-like cloak with a knot to keep it steady. He also has untrimmed fingernails and yellow teeth.
His villainy comes out of jealousy of Sheen's relationship with The Emperor and that he has his old position as royal adviser. Also, he has a odd relationship with his mother as shown in The Boy Next Dorkus as one of his comment cards asked where would he go if he want back in time. He said he would go back in time he would congratulate his mother for giving birth to after she gave birth, but in Thanksgetting, he was mad at mother for never giving him an action figure he always wanted mainly because it burns him on fire with its fire breathing action. One of his schemes involves a cluster bomb that blew up.
