Spinoffs
Batman Beyond spun off an animated series called The Zeta Project, featuring a revamped version of the synthoid Zeta from the Batman Beyond episode "Zeta." Batman would guest-star in the episode "Shadows." The supervillain Stalker was to have appeared in The Zeta Project episode "Taffy Time," but did not make it. The second season episode, "Ro's Gift," has an appearance made by the Brain Trust from the Batman Beyond episode "Mind Games." Terry McGinnis/Batman was originally slated to appear in this episode as well, but was cut since Bruce Timm and company were working on Justice League.
