It is a black (or maybe invisible?) shadow cat like figure with a large lizard-like body, and a headset. He trails transparent purple fumes.
He revives fallen shells in the third season, Get Ready-Anti Home. After several anti-fandoms (people who hate all fandoms) managed to triumph over the characters (even Doodle 2 somehow) he was mysteriously incarnated. He found all the broken and dismantled shells, and took them to an unknown room where he used a strange move to reincarnate the carcasses.
