Mokusei Dai-Oh is based on a retro toy robot, specifically the "Mars King" (Kasei Dai-Oh) robots sold in the late 1960's. It has a very blocky and fixed appearance, with a drill for a right arm and a hammer for the left.
Its name translates to "Great Jupiter King", and is the source of its JPT model number.
 In the games
In battle, Mokusei Dai-Oh is a close-ranged fighter. Both of its arms are Hammer attacks, and its head is Destroy. It only has one head use, so wise strategy is the best way to ensure that Mokusei Dai-Oh takes advantage of the power it possesses. Its legs are bipedal-type.
