Baxter Stockman has a brown head with white goggles, a black mustache and an angry expression with teeth bared. He wears a silver flight helmet and silver armour piece first used for the Ninja from Ninjago. His torso is white with a light purple shirt and white armour. His torso also features brown suspender and a brown and grey supply belt. Baxter's legs are blue and depict blue jeans.
The turtles first spotted Stockman trying to break into a building. They then fought him and threw him in a dumpster. After Michelangelo accidentally left his "T-Pod", an advanced music player made by Donatello, Baxter found it and used it to advance his armour. He used his new suit to attack a business place he got fired from. The turtles later heard about this on their television and decided to investigate. They then found Stockman and were barely able to fight him. The armour's left hand turned into a Mouser when it was taken off. Donny noticed how the T-Pod was evolving to Stockman, who Michelangelo nicknamed "Stockman Pod". The turtles then went to fight the Stockman Pod again, this time winning by throwing a bee hive at Baxter's exposed head, and destroyed the T-Pod.
Later, Baxter used his mousers to attack Leonardo and Raphael (The "A" Team), while Donatello and Michaelangelo (the B Team) took on a lone Dogpound. The B Team was easily crushed, while the A Team creatively got rid of the mousers, only for more to come out, because of a special spray Baxter put on him. Raphael was able to defeat him by opening his spray with a Ninja Star and spraying Baxter and Dogpound. When Dogpound brought him to Shredder, Baxter was forced to become a member of the Foot Clan and create Fishface's breathing aperatus and robotic legs, which he had problems with because of his fear of Shredder.
- His armour is the same as the Ninjago ZX armour.
