When the World's Mightiest Man steps into the Wreck Room, for a moment or two the World War II veteran looks decidedly out of place in the super-tech environment. A moment later, though, as the combat drones rise around him, their laser cannons priming, Captain Wonder's manner changes. Gone is the hesitation; the unsurety; ladies and gentlemen, the Captain of the Sun and Stars is on the field. Flying faster than the eye can see, he falls among the combat drones like a wolf among sheep, his hammer-like fists shattering steel and plastic apart with blows that could seemingly crack a skyscraper in twain! The small confines of the room hardly seem to hold him, and sure enough by the time he's done pieces of the combat drones are literally bouncing off the walls.
A few moments later, his training exercise begins. Fred knows full well that the walls rippling away around him are an illusion, the rise of tenements on either side just a holographic projection. But as his opponent, a hard-light construct with a familiar visage lumbers towards him, Fred has a moment to wonder if it isn't _too_ real. As the giant glass-headed robot with the swastika on its breast raises its arms to squish the flying golden bug before it, Wonder flies into it with an impossible blur of speed and a crack as his fists make contact. The subsequent fight between the Golden Guardian of Good and the Eisenmech of the Aryan Ape is a straight-up brawl between two power-packed pugilists of preternatural potency, all of it played out in the small confines of the Wreck Room, one that comes to an end only when the simulated Nazi robot disappears in a flash of light.
As the gauges in the control room beep, recording the energy absorbed by a god's punches, the recorded image of one of the biggest superbrawls of the 1940s fades away around Wonder. Shaking his head, an odd look on his face, he leaves the room with a wry "Well, that was fun."
