Big-Zam (メガモビルタンク ビグ・ザム) is a vehicle in Superior Defender Gundam Force.


A large mobile armor type weapon, the Big Zam is able to transform from a caterpillar tank mode to a bipedal mode. Developed by the Dark Axis as part of their battle forces, it was deployed in large numbers in Ark to combat the Tenshi Castle. With their help, Kibaomaru's forces were able to capture the Tenshi Castle, but at the cost of 29 Big Zams being defeated (this is most likely because such a large force of Big Zams would have destroyed the Tenshi Castle, whereas Kibaomaru wanted it captured). Those units were left behind and currently litter a battlefield in Ark.

A single Big Zam was deployed in Neotopia, piloted by Zapper Zaku, Grappler Gouf and Destroyer Dom, on a mission to cripple the Super Dimensional Guard's base in preparation for the massive invasion of Neotopia. Despite various mishaps caused by the bumblings of the Dark Axis trio (such as making a boomerang-type weapon nearly knocking the Big Zam off the base and causing the turrets to fire at separate parts of the Big Zam), The Big Zam was able to disable the Blanc Base. The Big Zam however was also severely damaged in the attack and was crushed under the Blanc Base.

Zapper Zaku, Grappler Gouf and Destroyer Dom are able to salvage one of the Big Zams on Ark and add it to the forces of the Genki Energy Force when they join Genkimaru.



  • These Ark deployed units had a special armor coating applied, as a reference to the Big-Zam inspired JMA27T Fantoma.
  • The tanks are based on the MA-08 Big Zam.
