Hei Hou encountered Sonic the Hedgehog and Tails in Mushroom Hills where it swung its axe at Sonic, who managed to avoid the surprise attack. Sonic managed to avoid another swing and attacked it from behind, finishing off the robot. It was later either rebuilt or duplicated by Archimedes and sent to attack Knuckles the Echidna during an early lesson that the enigmatic Fire Ant sought to teach his pupil.
