Two beings of energy trying to evercome each other and there respective powers. Who takes the cake and eat it in the end??
Captain Atom's Dilustel skin is tied into the Quantum Field, which enables him to absorb and manipulate theoretically infinite amounts of energy, limited by his willpower and imagination. This energy can be used for flight (which is generally faster than the speed of sound in Earth's atmosphere and up to half-light speed in the vacuum of space), super strength (shown at times to be on par with Martian Manhunter, defines his level of strength second only to Superman's among the heroes of the DC universe, though as Monarch he was capable of effortlessly overwhelming three versions of Superman), durability (he has survived exploding nuclear weapons, and even energy sufficient to wipe out all life within the Universe of Earth 51 - although this was his own energy) self sustenance and life support (allowing him to live and even speak in space), and controlling energy of any form. In addition to high speed flight he has been shown to possess enhanced reflexes. Atom's abilities stem from his link to the Quantum Field, which provides a virtually infinite source of Quantum Energy, which can be used for a vast number of effects. He commonly manipulates his energy into force field bubbles, or explosive "bombs," but the most common form is a simple energy blast. Atom has been shown to be capable of manipulating even exotic energies such as magic, and has a high degree of resistance to such attacks.
A Mutant that possesses a vast psionic ability to manipulate and alter reality. He existed in a state of pure psionic energy and could take possession of human bodies that his energies eventually "burned" out, killing them (including his own original body). Proteus also possessed telepathic abilities. His reality manipulation powers allow him to transmute matter and bend the laws of physics according to his imagination within a certain distance. Using this power he can easily turn a building into liquid, turn a vehicle into bees that attack at his mental command, transform energy into matter, manipulate weather, or strip a person of their mutant powers. He often reverses local gravity, opens fissures in the earth, and stretches people painfully into liquid shapes (they return to normal when he no longer concentrates on manipulating their bodies). Use of this ability tends to speed up the rate at which his body will burn out. Proteus' reality warping ability is contingent upon line of sight: if he shifts his sight to another object and warps it, the previous object he was warping will return to normal.
