From the world of Batman Beyond comes Zeta, an experimental infiltration robot designed to be a government agent. With an arsenal of weapons and technology, including a holographic self-projector allowing it to assume any identity, Zeta is the ultimate assassin. But when Zeta's programming evolves, he develops a conscience and refuses to perform for the government. Now, Zeta is the enemy, and Agent Bennet wants to put this rogue robot down before it endangers humanity. Zeta takes to the streets and finds a friend in Ro, an orphan also on the run. These two form a wary alliance that grows to a friendship as they travel together through The Zeta Project's 12 Exciting Season One Adventures. As pursuer Bennet's anger and persistence grow, the question becomes: Who's the real threat to humanity?
