Bandock was the four-legged robot space fortress commanded by Butcher. For the first nine episodes it serves as only a headquarters near Earth's orbit where Mecha-Boosts are produced. In episode ten it comes to Earth and releases a series of Beltar Tanks to defend itself. After Mecha-Boost Tracid is destroyed, Zambot 3 attempts to attack only for a barrier to knock it away. In the next episode it is forced to flee back into space after being destroyed internally by Zambo Ace. Returns to Earth in episode 18 as the primary facility for converting humans into living bombs, keeping itself underwater at well over twelve hundred meters below the surface until Zambot 3 discovers its location. The head detaches itself and starts firing extremely large torpedoes at Zambot 3 from its mouth as well as stops the Moon Attack with an energy barrier. It retreats to space again in episode 19 after large quantities of damage and the energy barrier being destroyed by Zambot 3's Moon Attack and destruction of Mecha-Boost Gaidar.
