Baron Waclow Jozek first appears on the Batman: The Animated Series episode The Cape and Cowl Conspiracy. Batman investigates a theft of bearer bonds intended for the starving people of Byelocroatia. One suspect is Baron Waclow Jozek, a European nobleman also known as The Baron. He confronts Jozek, who tells him that Josiah Wormwood, the 'deathtrap specialist', is responsible for theft. Jozek contacts Wormwood and sets him a task; to use his talents to get Batman's cape and cowl. While the real Jozek was out of town, Batman impersonated him in order to get information and a confession out of Wormwood.
