The Zeta Project

From Superdickery

The Zeta Project was a spinoff of Batman Beyond which in turn was a spinoff of Batman: The Animated Series.

Basically, Zeta; a robot that was meant to be a spy/assassin, but went against his programming, is on the run from government agents. Had two crossovers with Batman Beyond, an initial one that introduced the character, and a second appearance after the show was made. Noteable for having the guy who plays Red Foreman on That 70's Show doing the voice of the bad guy.

The shortest lived of the DCAU series.
