The Krybots were the Troobian Robotic Foot Soldiers.  They did not feel pain or emotion.  They knew no mercy and were programmed to follow orders and destroy.

The Blue Head Krybots were Emperor Gruumm's elite robotic guard.

The Orange Head Krybot was another one of the styles of Robots that Broodwing sold to Gruumm.  They were extremely more powerful than the normal Krybots and Blue Head Krybots.  Orange Heads were equipped with swords capable of dispensing a power lightning blast.
