I was doing some reserch on Captain Atom and I found something very interesting.
Captain Atom's metal skin is tied into the Quantum Field, which enables him to absorb and manipulate infinite amounts of energy, for an infinite amount of purposes the amount of which he can do is limited solely by his will power and imagination. He truly reinforces this fact when he realized that the Quantum Field is completely under his control and he can do anything he wishes. With this realization he tests his powers and by simply thinking of it, he is able to instantly create a replica of our Earth from nothing, complete with life. His power was such that he was able to easily create his own replicas of Superman, Flash, Firestorm and even his own Spectre. His power is such, that he went even further and by simply thinking of it, was able to instantaneously create an entire universe out of nothing, and just as easily destroyed it, but he has never used this level of power again as a result of him mentally limiting himself. Captain Atom's energy absorption power is second to none in the DCU, as he is able to absorb any form of energy and store it in his person. Captain Atom can fire and control energy of any form. He commonly manipulates his energy into force field bubbles, or explosive bombs, but the most common form is a simple blast. Over the years, Captain Atom has become an expert at his energy manipulation and can fire from any point on his body, though he usually uses his hands for ease of aiming. He can fire in multiple directions at once or from every point of his body at once. Several times he has "detonated," releasing a massive amount of energy at once, destroying objects within a certain radius.
