Mirror

Mirror stands as a humanoid machine towering well above any person, its torso bristling with numerous arms. A lone eye peers out through narrow slits cut across the surface of its head.

Much like G4, Mirror is a haughty machine fixated on gathering data solely from formidable heroes, and it sneers at anyone ranked below S-Class who dares confront it. For all its analytical purpose, its judgment is skewed. It gauges Saitama by his plain looks and lowly rank instead of his true power, dismissing him as a nobody. That miscalculation proves fatal, since the hero it wrote off destroys it with a single blow.

As a Dragon-level Machine God, Mirror is a fearsome combatant. It is armored in materials so durable that Suiko, strong enough to shatter a giant training robot in one move, cannot break it; her best strike merely dents its head, which the machine promptly reshapes while dismissing the harm as a fraction of a percent. Its physical power lets it toss the seasoned martial artist around like a toy, and every one of its hands can conjure destructive energy spheres able to punch through buildings, which it can also gather into one enormous blast. Propulsion built into its legs keeps it aloft, while onboard sensors let it read shifts as subtle as a spike in an opponent's body temperature, and internal systems both diagnose damage and knit deformed metal back into shape.

Mirror tears into the Hero Association headquarters demanding a fight with King, and after overpowering Suiko, Butterfly DX, Chain'n'toad, and the wider Hero Name Victims Association, it charges a colossal beam at the building to force King out, only for a shrunken Overgrown Rover to blunt the strike. Saitama finally steps in, and though the robot holds data on him, it brushes him off as another weakling and taunts him by his hero name, Caped Baldy. The insult earns it a single punch that smashes it through wall after wall, its wreck coming to rest in the safe room where it flattens McCoy.
