Stockman's next appearance, in season five's "Landlord of the Flies," was a distinctly anomalous one. Without the computer at his side or any explanation for how he escaped his interdimensional banishment, Stockman was already back on Earth when the episode began, with a new ability: his continually devolving fly-like mentality had given him the ability to communicate with other flies, and he assembled the insects into an army in a plot to get revenge on Shredder. By this time, however, the Technodrome was stranded in the polar wastes of the arctic, and the frigid air proved distinctly inhospitable to Stockman and his fly family, stopping his scheme before it even got started. Krang was intrigued by his new ability, however, and struck a deal with Stockman, promising to transform him back into a human again if he helped them. Stockman proceeded to terrorize the city with his family army, but was once again shot off into another dimension at the episode's conclusion by Donatello's portable portal generator.
