These enhanced versions of their human counterparts in the Foot Soldiers were built by the Kraang Hive Mind on the Shredder's request, due to the fact that the ordinary human Foot Soldiers were being defeated by the turtles too easily. As far as the robots' appearance goes, they are dressed exactly the same as the regular Foot Soldiers and so, if they stood side by side, the two would be almost impossible to differentiate between. While in combat with skilled opponents like the Turtles, they are not much more capable than the original foot soldiers, one of these robots' prominent features is their ability to learn from and quickly adapt to their foes' own martial arts moves and combat techniques in a matter of seconds, enabling them to quickly overwhelm an unsuspecting enemy. As a consequence, the best way to defeat them is to constantly be unpredictable and come up with new moves/techniques to surprise them with.
The Footbots also differentiate from their predecessors in the armament they wield and their ability to morph into a more formidable battle form. When first encountered, the bots look normal and are armed with normal ninja weaponry; e.g. katana, tanto, naginata, kama, shuriken and kunai. However if the opposition is observed to be stronger than normal, the bots can morph their arms into more formidable weapons, including large curved blades, drills, huge mace-heads and buzzsaws. They can also rapidly extend another pair of arms which also can possess the same enhanced weaponry.
Follow The Leader - Debut
Target: April O'Neil - The Footbots get upgraded with two extra, hidden arms, each of which have weapons protruding from where the hands would be. They learned how to ice skate, among other things.
The Good, The Bad and Casey Jones - They follow Casey (who is following Raphael) all the way to the Turtles' lair and they begin invading it, one by one...much to everyone's dismay. However, the Turtles, Splinter, Casey and April manage to overwhelm the robots after a while, and are able to defeat them in combat. It is unknown if a robot gave way the Turtles' position or not.
The Lonely Mutation Of Baxter Stockman - They present new gliding abilities, with fabric wings similar to flying squirrels'.
Broken Foot - This episode introduced upgraded versions of the Footbots called the Elite Footbots. Besides being stronger than the ordinary Footbots, they resemble Chrome Dome except for the fact that they wear metal kasas on their head.
- The Footbots' noises are similar to the cat noises made by the M.O.U.S.E.R.S.
- A Robotic Foot Soldier action figure will be released in 2014 by Playmates Toys
- The robotic Foot Soldiers, in sharp contrast to the 1980's versions, are not just flimsy cannon fodder, but deadly, nimble fighters who have excellent martial arts skills and are superior to their human counterparts in almost every way, shape, and form. The most telling sign of their abilities is when one was able to hold its own against both Raphael and Casey Jones at the same time.
- When their eyes glow red, they make a sound, indicating they have learned something new.
