Nuclear Man

Nuclear Man is a supervillain who appeared in the movie Superman IV.

History
Nuclear Man was created by Lex Luthor from a strand of hair containing Superman's DNA, made into a "genetic stew" which was birthed into a living being when Superman threw the nuclear missile containing the device that had the "stew" into the sun. In Superman's first encounter with the Nuclear Man, he pierced the Kryptonian's skin, causing him to lose his powers and his health. After Superman restored his powers and health with the use of the energy module from his star ship, he stopped Nuclear Man for good by causing a sudden solar eclipse when he moved the moon in front of the sun, then dropped him into the heart of a nuclear reactor where he would become an abundant source of energy.
