Foot Ninja...ATTACK!" - Master Khan
They appeared throughout Back to the Sewer and Mayhem From Mutant Island. They first appeared during the "Shredder Wars" that were seen briefly in Tempus Fugit. Unlike the other Foot Ninja's who served Ch'rell the Utrom Shredder and Karai's Foot Ninjas, their armor is dark blue and styled after the Cyber Shredder's armor. Although some units wore red uniforms. The red variant of these Foot Ninja can be seen in Mayhem From Mutant Island.
After the defeat of the Cyber Shredder, most of the Cyber Foot Ninja's would join Karai. In the Turtles Forever movie, they officially joined Ch'rell who had returned from exile when the 1980s Shredder and Krang rescued him.
The Cyber Foot Ninjas would be briefly seen as part of the Utrom Shredder's army during Turtles Forever. When Karai upgraded the 1988 Shredder's Technodrome, the Cyber Foot Soldiers were shown getting involved. Some of them were assisting in the maintennce of the Technodrome while a select number of Cyber Foot Ninjas were each given a injection of Krang's Mutagen (which was engineered from the mutagen that Hun got exposed to) and were mutated into Mutant Foot Soldiers (two of which resembled Rahzar and Tokka). A modified version of the robotic 80s Foot Soldiers were also part of Ch'rell's army.
- The Cyber Foot Ninja appears as the alternate costume of the standard Foot Ninja in Teenage Mutant Ninja Turtles Smash-Up.
- A golden-colored Cyber Foot Ninja is used as the first boss in Teenage Mutant Ninja Turtles: Arcade Attack. In later levels, the golden Cyber Foot Ninja are reduced to standard enemies, alongside standard, red, and blue versions.
The name "Cyber Foot Ninja" is never used in the series or on any officially released supplemental material (including entries on the 4Kids blog). The ninja are referred to as "Future" Foot Ninja in Arcade Attack. The name of "Cyber Foot" actually comes the descriptor on Stephen Murphy's blog of Michael Dooney's action figure design of the character (which never even was released) 1. The name "Cyber Foot" is also used on the labeling for the figure's prototype seen in an issue of ToyFare magazine, indicating that this may have been the name that Playmates Toys may have intended to give the figure.
