Robotman

Robotman is a mecha from Microman.

Remember when me and the Doom Patrol fought a man who wasn't there in a giant painting? Good times.

Robotman (ロボットマン Robottoman) is a mecha that can be summoned by M121 Mason. For some reason, it looks a lot like a Biotron.

Fiction

DreamMix TV World Fighters

As part of DreamMix TV's attempt to pull in more ratings, M121 Mason was invited to battle bunches of other beings, including Optimus Prime and Megatron on the television show World Fighters. In those battles, Mason could summon and climb inside Robotman, who would attack foes with a mighty kick, chop, or ascending spin. DreamMix TV World Fighters

Notes

• Robotman was the first toy made by Takara that was capable of changing from a robot to a vehicle, albeit through partforming rather than transformation as we know it today.
• The Robotman toy became Biotron when the Microman franchise was brought to the west as Micronauts.
