Gary, in the Ratchet & Clank: Up Your Arsenal Official Strategy Guide‏‎.

Gary, along with his partner Helen, was a professional robot gladiator team on Annihilation Nation. Gary was armed with a massive machine gun and was the stronger of the two. Helen and Gary fought tag-team style. When one took too much damage, they would switch with each other. Gary, as detailed by his voice and mannerisms, was a powerful warbot, speaking like a drill sergeant and commenting on Helen's performance.
