An early Icebot

Icebots were club-wielding robots invented by Dr. Ivo Robotnik, which appeared similar in design to SWATbots except their heads were in the shape of ice cubes. They were seen in the Arctic area of Mobius, where they were herding and directing the hypnotised Walrus Herd. A year later, new models of Icebots created by Dr. Eggman simply looked like Shadowbots. (StH: #31, #32, #109)

A completely different form of Icebot was used on the Egg Carrier to aid Chaos in his fight against Sonic and Knuckles. However, the "ice-bots" proved vital to Chaos's defeat, when Sonic used them to freeze Chaos solid, enabling Sonic and Knuckles to break it apart. (SSS: #13)
