Metalman (メタルマン, Metaruman) is an alien, humanoid species that resembles robots in physical appearance that reside in both Universe 6 and Universe 7. The only known Metalman is Auta Magetta, from Universe 6. Metalmen come from Galactic System 66950.
Metalmen are strong and durable beings, but they lack the mental strength to go along with their powerful bodies. Metalmen are very sensitive, and Whis states that if they are insulted even once, they immediately lose their will to fight.
The Metalmen weigh more than 1,000 tons so it's difficult to move them during battle. This heavy body allows the Metalmen to out-stand many powerful attacks their opponents strikes at them.
