Iron Z (ZERO)

Iron Z is a prototype of Mazinger Z along with its counterpart Energer Z.

Appearance
Iron Z resembles its successor save for a few major differences such as a smaller crown and horns, a grill-less mouth, as well was more box-shaped chest plates. It features what appears to be a prototype Hover Pilder on its head

Abilities
Iron Z was equipped with a specialized armor that is even tougher than aggregated diamond nanorods, but still not as durable as the Alloy Z armor of the prototype Mazinger Z. It appears to have no other weapons aside from its fists.

History
Iron Z was created alongside Energer Z by Dr. Juzo Kabuto. However, he ordered it and Energer Z to destroy each other after they were rendered obsolete by the prototype Mazinger Z, which surpassed both of them in every possible way.
