The exoskeletons are mechanical suits that the Utroms use to blend in with the humans, which carry the Utrom in the stomach section of a humanoid body. While they function perfectly well as robotic carriages, the exoskeletons can be perfectly disguised as a human being if the Utrom desires. In fact, their movements are natural enough that an Utrom can even fight using one.
They were invented by the Utroms using some parts of their ship, but an early model was stolen by The Utrom Shredder from a yellow Utrom to form his Shredder armor. They are highly maneuverable, to the point that Shredder became a highly skilled fighter in hand-to-hand combat.
Cody Jones has an exoskeleton in his trophy room.
In Wedding Bells and Bytes Mortu's crew have exoskeletons.
