Clayface escapes by water, but Batman pursues him in his Bat-Boat until the former's potion wears off and he nearly drowns due to his inability to swim. Batman saves Hagen and hands him over to the police. In the episode "Curses! Oiled Again", Clayface collaborates with Catwoman to steal a shipment of oil bound for Gotham City during a cold snap and steal the country's oil supply. However, Batman, Robin, Batgirl, and Bat-Mite intervene and defeat the villains. In the two-part episode "Have an Evil Day", Zarbor enlists Clayface, Catwoman, the Joker, and the Penguin to keep the Dynamic Duo busy while he steals America's nuclear power plants.
