Mirror

Mirror (ミラー, Mirā) was a Machine God battle robot presumably created by The Organization. It was killed by Saitama.

Appearance
Mirror is a human sized robot. It has many arms protruding from all over its torso and has a single eye exposed by thin slits running across its head. Overall it has a very rounded and simple design.

Neo Heroes Showcase Arc
Mirror is seen standing in the ruins of Y-City and is found by Suiko. Mirror tells Suiko to bring it King, remarking that her data is irrelevant. Suiko then lunges towards Mirror.

Abilities and Powers
Being a Dragon-level threat and a "Machine God" like G4 and G5, it can be assumed that Mirror is a very powerful being, and it is likely a very powerful upgraded version of them. Mirror easily overwhelmed Suiko, who claims to be stronger than her brother, able to quickly adapt to Suiko's techniques and her strongest attacks while sustaining almost no damage. However, none of its immense powers are strong enough against Saitama.

Immense Strength: Mirror has a high level of strength, being able to quickly overwhelm Suiko, a master martial artist with similar power to Suiryu, as well as two A-class heroes with minimal effort.

Immense Durability: Mirror possesses great durability, being able to handle Suiko's attacks without difficulty, and only sustaining 0.4% damage from Suiko's Void Quaking Tiger Fist.

Energy Projection: Mirror has the ability to generate balls of energy from all of its hands, each of which contain devastating power.
