Dr. Gilbert Zan is a playable character introduced in Streets Of Rage 3. Formerly a syndicate scientist, it is Zan who warns Blaze about the robot conspiracy (or in the Japanese version, the Rakushin bombs) and triggers the events of SoR3.. Zan himself is partially robotic (a cyborg). Unlike the other characters in SoR3, Zan has no specialized blitz weapon attacks; every weapon turns into a ball of energy on touch and results in the same projectile attack. His special techniques are the Electric Body and Electric Reach, which both use his robotic bodyparts to deliver a shock to his opponents.
- Zan is the only robotic playable character in Streets of Rages history.
- After defeating Shiva in City Hall, he calls him a "worm".
