The High Evolutionary was exposed to his Evolutionary Accelerator machine, giving him superhuman abilities by accelerating his personal evolution. The Evolutionary has shifted between various levels of evolution over the years, sometimes deliberately sometimes not, with different power levels as well. Often he maintains some level of superhuman power while incorporating the Evolutionary Accelerator machine into his armor, letting him evolve himself further at will. The unstable Isotope E caused the High Evolutionary to uncontrollably fluctuate between God-like powers and Neanderthal-level ability and intelligence.
