Otto the Odd along with the Ringmaster are partners in crime, pretending to be a mere assistant and circus clown. He was later revealed to be the brains of the operation, at least in terms of the technology. He also claimed that the Ringmaster worked for him, though Otto did this whilst betraying his partner, so it a dubious assertion at best. When everyone was turned back to normal, Otto turned Ringmaster into a fearsome Baelrog face, big fist, crab clawed and tentacled monster, as a final offense in desperation. Alongside Ringmaster, he was sent to prison.
He later returned where he had a lair disguised as a space prison with a robot version of the warden. He was collecting people and items for his collection as the best anything in history. He hired Electro J. Fudd into hunting Ace (who Otto considered the Best Action Hero in History) and Otto lured the Loonatics out with a Massive robot. He changed his target to Danger Duck (who admitted to Danger Duck that he's the Best Screw-Up Action Hero in History) and when Electro caught him, Otto decided to use his lazer to freeze them in place. Both Electro and Duck were on the run until Ace appeared. After robot double against robot double, Otto was hit by his own lazer.
