In all of his versions, The Beyonder has the general ability to manipulate reality. The original Beyonder was considered to be the most powerful being in the multiverse, having power surpassing Cosmic Entities, such as The Living Tribunal and Eternity. He was capable of causing a multiversal wide destruction, and took over the entire earth with a mere thought. He also had vast psionic abilities, which enabled him to scan the minds of the entire world, neutralize psychic probes from powerful telepaths, erase the memories about himself from every human being on the planet, among other abilities. His cognitive capacity is such that he can assimilate knowledge from the entire multiverse. He can also easily change states of matter, and has a host of other different powers. He is endowed with superhuman strength of such an extent that it is potentially incalculable. Using his ability to manipulate reality, he can, in effect, regenerate damage done to his body by simply willing it repaired. Additional powers include teleportation, flight, the ability to choose his own physical resistances and attributes, as well as the ability to move others from one place to another via teleportation, such as the heroes and villains he moved through spacetime to his 'Battleworld' construct in the original Secret Wars. However, The Beyonder, went through several retcons, which significantly reduced his power. The retcons made The Beyonder arguably weaker than many Cosmic Entities, but he still retained his virtually infinite reality warping powers. Inherent in his near-limitless psionic abilities the Beyonder has the potential to affect reality in a manner that could, in theory, simulate virtually any power.
