More villains with new interpretations are once again introduced, including Tony Zucco (voiced by Mark Hamill, who voiced the Joker in the DC animated universe), Killer Moth (voiced by Jeff Bennett), Black Mask (voiced by James Remar), Rumor (voiced by Ron Perlman), the Everywhere Man (voiced by Brandon Routh), Harley Quinn (voiced by Hynden Walch), and Francis Grey (voiced by Dave Foley). The season also brought an end to Ethan Bennett's version of Clayface, including a storyline that redeemed Bennett by curing him of his condition. This gave writers the opportunity to introduce Basil Karlo's version of the villain (voiced by Wallace Langham in the first appearance, and Lex Lang in the second appearance). Season 4 also featured a redesign of Bruce Wayne, with a more square facial and chin structure, making him reminiscent of the DC animated universe Batman design.
