They're general-purpose humonoid robots & they're unlike any other humanoid robots developed to date made by Dr. EggPlankton.

Besides its default set of motor functions, a powerful learning AI function enables it to mimic perfectly any human motion captured on its mocap sensor arrays, even on Jack, Patricia, Sonic, Tails, Knuckles, Amy Rose, Shadow, Rouge, Blaze, etc.

With this ability, the Combots are suitable for a wide spectrum of applications from the EggPlankton Empire's military duty.

However, these Combots are the unique version customized for hand-to-hand combat. Dr. EggPlankton even set their Colours on the Combots to either White, Blue, Red, Yellow, Green, Orange, Purple, Light Blue, Brown, Grey or Black. The Combots can change colour & disguise themselves into any other Character on their Mocap Sensor Arrays & still be in their Combot Bodies.

Its disadvantage is that it cannot copy any sacred spells or any of the latter.

Example: Blue Hedgehog Combot = Sonic
