In his final appearance, in season seven's "Revenge of the Fly," it was as if "Landlord of the Flies" had never happened: Baxter was in limbo, with the computer's remains, and with Krang credited for trapping him there. It was, ironically, Krang who was responsible for releasing Stockman, when he attempted to open a portal between Earth and Dimension X, and the malfunctioning device wound up opening a gateway to Stockman's prison. Quickly escaping, Stockman plugged his computer friend into the Technodrome's databanks, giving him complete control over the fortress, allowing him to lock up the Shredder and his cohorts. Seeking revenge against the entire world, Stockman stole a sample of Krang's mutagen, and combined it with the genetic material of various insects stolen from a research lab, using the resultant concoction to transform humans into mutant insects, including the crew at Channel 6. The computer reminded him that he had forgotten about the Turtles, and he used his insect minions to capture them, but when questioned about what, exactly, they had ever actually "done" to him, Stockman admitted he could not even remember. Eventually, the Turtles were able to overpower Stockman, and forced him to lead them back to the Technodrome so that they could steal the Shredder's retro-mutagen ray and return the mutated humans to normal. In the chaos that ensued, the computer was destroyed, and once the retro-mutagen ray had been found, Stockman snatched it up and flew off through a dimensional portal, intending to use it to return himself to normal. While the Turtles gave chase, the Shredder attempted to close the portal of the group before they could re-emerge, but the Turtles beat the clock, reclaiming the ray and making it back through in time, Baxter, however, was not so lucky, and was once again lost in limbo with the surviving remnants of the computer, never to appear again.
