Dr. Baxter Stockman is a major antagonist in the 2016 live-action sci-fi action comedy superhero film TMNT: Out of the Shadows. He is a former TCRI employee, a genius but mad scientist, criminal and a terrorist who aids the Shredder and the Foot Clan in the processing of their plans. He first appeared in a quick cameo appearance in the 2014 first film Teenage Mutant Ninja Turtles.
He is played by K. Todd Freeman as a silent cameo in the first film and by Tyler Perry as a secondary character in Out of the Shadows.
He only makes a quick cameo when young April O'Neil asks Eric Sacks what are those experiments for. In the scene, we see Sacks, April's dad, and Baxter Stockman standing in the background. In a later scene, Stockman's name was written on a whiteboard by April when she is trying to put together her knowledge of Project Renaissance.

Although a prominent industrialist and a genius who graduated MIT at 15, he is soon revealed to be working with the Foot Clan, using salvaged alien technology to rescue Shredder from jail by teleporting him away during a prison transport. When Shredder learns that the component Stockman has is one of three parts to a teleporter that would allow the alien warlord Krang to dispatch his ultimate war machine to Earth, he arranges for Stockman to assemble the other pieces. Once the portal device is complete, however, Shredder dismisses Stockman's efforts and has him taken away to their headquarters in Tokyo. Realizing that Shredder has betrayed him, Stockman unsuccessfully tried to break free of the Clan men taking him away as he screamed for mercy. At the end of the film, April O'Neil states that Stockman remains at large.
Stockman has not yet mutated into a fly in the live-action movie series, although it's likely that event, which Tyler Perry hoped would happen, was planned to be in the third movie.
Stockman was slated to return for a sequel to Out of the Shadows, but due to disappointing box office returns the sequel was scrapped.
