The Batman: Season Four features a redesign of Bruce Wayne/Batman, that is more reminiscent of the DCAU (Bruce Timm) Batman. The season also introduces Dick Grayson as Robin (Evan Sabara) into the series as well as other characters such as Lucius Fox (Louis Gossett Jr.). More villains appear such as Tony Zucco (Mark Hamill), Killer Moth (Jeff Bennett), Black Mask (James Remar) & Number One (Diedrich Bader), Rumor (Ron Perlman), Everywhere Man (Brandon Routh), Harley Quinn (Hynden Walch), Francis Grey (Dave Foley), and a new Clayface (Wallace Langham). Batgirl returns this season as well, and is now officially part of Batman's team.
