known as the Flash. After capturing Barry because his ability to traverse the multiverse unaided made him a dangerous variable, the Anti-Monitor created an anti-matter cannon that would destroy the then-five remaining Earths with a concentrated beam much faster than the wave of entropy he had originally unleashed. The cannon was destroyed by the Flash when he escaped and forced the energies of the weapon's power source into itself, causing it to explode and Barry to disintegrate. In addition to possessing vast size (varying from about nine feet to hundreds of meters tall), vastly superhuman strength, extraordinary durability (by the end of the Crisis series he was able to effortlessly withstand blows from Superman and even surviving a blue star going supernova), the ability to project destructive bolts of energy, and greatly augmenting another being's powers (as he did with Psycho-Pirate, whose powers were increased to levels too much for him to handle), the Anti-Monitor also possessed reality-warping abilities, which he displayed by removing Psycho-Pirate's face. The Anti-Monitor also commanded an army of Qwardians and shadow demons and had access to highly advanced technology capable of shifting, merging, or destroying entire universes. By far, his most devastating power was the ability to absorb the energies of his surroundings into himself; once he fused with his anti-matter universe, he went even as far as absorbing the energies of entire universes. In addition to devouring the energies of untold numbers of universes, he also absorbed the energy of "over one million worlds" in his own anti-matter universe to gain the power to travel to the beginning of time to attempt to stop the creation of the positive matter universe. When Earth's heroes followed him to the beginning of time, he then absorbed all of their power and energy; this made him strong enough to alter the creation of the universe until he was opposed by the Spectre. During his final battle in Crisis on Infinite Earths #12, the Anti-Monitor maintained his power by "feeding on" a nearby star; and when his power was drained and he was reduced to a state of near-death, he absorbed his own anti-matter demons to rejuvenate himself. The Anti-Monitor is not immortal, but may be ultimately indestructible so long as the anti-matter universe exists; having been destroyed with an immense effort at the end of the Crisis, he was recreated by his universe, just as he had
