Batman Beyond Season 2 Episode 20

Zeta

Terry becomes suspicious when his biology teacher starts acting oddly. The strange behavior culminates in a manic chase and shootout with federal agents after school, leading him to get involved as Batman. When Commissioner Gordon and her men find the teacher gagged and bound in her home, the truth comes out: an intelligent synthoid code-named Zeta is on the loose. Designed for stealth and assassination, it has the ability to disguise itself as any person using a holographic generator. Batman joins in the hunt for Zeta, but when he corners the robot he discovers that Zeta ran away from the federal agency because he doesn't want to kill. Gary Cole makes his first and only appearance as the voice of Zeta, before Diedrich Bader assumed the role for the Zeta Project spin-off series. Joe Spano makes his first appearance as agent Bennet.
