Metallo is a radioactive cyborg intelligence who depends on Green Kryptonite as his energy source, making him an enemy of Superman. This deadly radiation can kill the man of steel through exposure alone, although his cybernetic enhancements make him very physically powerful. He is a former soldier who was used in experimentation by the United States Army, eventually giving him the ability to project his consciousness into any technological device. His powers also include the ability to morph the machinery in his body accordingly. Metallo was created by Robert Bernstein and Al Plastino, first appearing in Action Comics #252. (1959) ||
