The Rotten Robot was the disguise of Viktor Rustoly.
He stole one of Doc Tinkerwell's Monsterbots and tinkered with it so that he could sit inside and control it. He wanted to ruin Tinkerwell because he thought the inventor had stolen his idea for shape-changing robots. (Scooby-Doo! and the Rotten Robot)
