The largest of the Buff Clan Heavy Mobile Mecha, the Zanza Lubu was nearly the equal of the Ideon in terms of physical strength. It was equipped with powerful claws, and presumably some beam weapons or missiles. However, by the time the small number made arrived with Doba's armada the Ideon's power levels were at their peak and the Zanza Lubu stood little chance against the Ideon Swords or Ideon Gun.

That said one example contributed to the destruction of the Ideon when its' pilot attacked the robot in a suicidal bid to prevent the robot escaping from the firing range of the Gando Rowa.
