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.
