Hun eventually found Stockman and brought him back to the Foot, albeit the scientist is now merely an eyeball, a spinal cord, and his brain in a jar. Stockman creates the Foot Mech soldiers, and survives the sinking of the Shredder's freighter ship during another battle with the Turtles. In the third season, Oroku Saki keeps Stockman around due to his scientific expertise, but Stockman feels threatened by the arrival of newcomer Dr. Chaplin, who impresses Saki with his own expertise. Stockman covertly sabotages some of Chaplin's efforts in order to not only keep his place in the Foot, but to simply stay alive. Stockman's attempts to sabotage Chaplin mostly fail and only backfire on himself. Stockman also enters an uneasy mutual understanding with Hun, who is enduring a period of humiliation and failure in the Shredder's eyes. The younger scientist idolizes Stockman and creates a new robotic body for him, earning some grudging respect and gratitude from the older scientist. However, Stockman nevertheless becomes a double agent for Agent Bishop and the Earth Protection Force. When the Shredder is finally defeated - killed with the Turtles, as far as they know - Stockman joins the EPF full-time as Bishop's second-in-command and head scientist.
