Aside from his regenerative abilities thanks to the Cadou, a parasitic organism created from a mold-infected nematode, Heisenberg's mutation also granted him superhuman strength. While his hammer was stated to be too heavy for an ordinary human to wield, Heisenberg could carry it with one arm with seemingly little effort, and was even seen shattering stone with the oversized weapon. In addition, the mutation also provided him with electric organs similar to Narke japonica, the Japanese sleeper ray, which connected with his nervous system and allowed him to harness electromagnetism, as well as control magnetic fields to manipulate metal objects. Heisenberg would later transform by stretching his body apart and spreading his biomass through a large mechanical apparatus he assembled in and around his flesh, becoming a cybernetic mutant. Mother Miranda considered him to be the strongest of the Four Lords and the one with the most stable mutation. The Japanese version of the above file, "Heisenberg's Treatment Book", states that the Cadou used to infect Heisenberg specifically formed the electric organ in his chest, which connected to his cranial nerves, essentially turning him into a human coil.
