Khan must have lost control of the Foot after Cyber Shredder's defeat because Karai was in control of the Foot once more in the movie "Turtles Forever". At this point, the Utrom Shredder returned by means of his counterpart, the Shredder of the 1987 series. The Technodrome became the headquarters for the Foot Clan of the 2003 series and the robotic foot soldiers were added to the Foot's fighting force after an upgrade with Utrom technology. Using Krang's mutagen reverse-engineered from the mutagen that affected Hun, they also added mutated some of the Cyber Foot where they were classified as Mutant Foot Soldiers and were not seen coming in contact with whatever they mutated into. While two of these mutants resemble Tokka and Rahzar, the rest of the Mutant Foot Soldiers consist of a sea creature-like mutant, a one-eyed mutant, a tiger-like mutant, a mutant with an octopus-shaped head, an insect-like mutant, a bat-like mutant, and some unspecified mutants. The Utrom Shredder kept the 1987 Shredder and Krang on, as well as Bebop and Rocksteady to help lead the Foot. However the Utrom Shredder turned on his counterpart and Krang later in the movie. The Utrom Shredder was eventually destroyed by the Technodrome's weapons. Karai most likely retook control of the Foot at this point.
