that he could get revenge on Superman for his brother's death. Like the previous Metallo, this one was also powered by kryptonite, although this newer version wore orange and green armor, as well as a green helmet to conceal the "new" identity he had created using plastic surgery (which turned out to be WGBS Staffer Martin Korda). This version of Metallo returned throughout the Bronze Age. His final appearance was featured in Alan Moore's "Whatever Happened to the Man of Tomorrow?" (1986). Powers and abilities Metallo's metallic body offers him a high degree of protection from physical and energy attacks. He has enhanced abilities and no longer needs to eat, sleep, or breathe. His brain is hermetically sealed inside a shielded alloy skull that has its own power supply. When he was first created, he was powered by a kryptonite heart; losing that, he subsisted on plutonium instead. Additionally, because of his cyborg body, Metallo possesses superhuman strength and speed, enough to pose a challenge and even a threat to opponents such as Superman (in that case, he also takes advantage of the weakening power of kryptonite besides his own strength). Over the course of his criminal career, Metallo's body would be decimated constantly by various circumstances. As such he would receive numerous upgrades or whole new chassis' to replace his damaged parts, such as by the obscure supervillain organization Cerberus, which modified him with a vastly superior body, one with lead-lined skull-plating and an anatomic layer that even Superman could not demolish. This gave him greatly enhanced strength and durability, coupled with moderate mechanical regeneration to repair internal damage. He was later outfitted with a larger LexCorp tech body, which gave him laser vision and further augmented his physical abilities. Soon after it was destroyed, Corben had received a new body from a fellow Kryptonite-powered supervillain Conduit; which gave Metallo radioactive blasts from his hands and could utilize geomagnetism to make him physically immovable, even by the Man of Steel, so long as he stood on solid ground or flooring within a building complex. Metallo would eventually sell his soul (or what was left of it) to the archdemon Neron in return for increased power, gaining the abilities to mentally control and absorb any mechanical or metal object he focuses on and transforming any technology (himself included) into an extension of his exoskeleton (an ability similar to Cyborg Superman).
