was able to jump from body to body, taking over the personality and causing the body to release Kryptonite radiation. K. Russell Abernathy After DC Comics' One Year Later jump, a scientist named K. Russell Abernathy was working on an experiment to use Kryptonite to develop a new energy source using isotopes. The experiment explodes, infusing Abernathy's body with radiation. Clark Kent, powerless, summons the current Supergirl to contain him. The transformed Abernathy, in a misguided attempt to prove his energy theories, goes on a violent rampage; this includes deliberately attempting to injure Kryptonians. He is soon subdued and imprisoned in Stryker's. Lex Luthor sends insectile warriors who free Abernathy from the prison. Abernathy is used in conjunction with large amounts of Kryptonite to free an ancient Kryptonian spaceship outta Sunstone. He later resurfaced in Action Comics #853, having Superman beaten until the timely intervention of Jimmy Olsen and Krypto. Clay Ramsay In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Kryptonite Man is reintroduced in Action Comics #5, by Grant Morrison and Andy Kubert. His origin is told in Action Comics Annual #1 (2012) (penned by Sholly Fisch). In this origin, Clay Ramsay was an abusive husband living in Metropolis. One night, Superman broke into his house while he was beating his wife and threw him into Hob's Bay. His wife subsequently left him and no one in the justice system could help him. Seeking revenge, he joined the mysterious "Project K-Man" (a private super-soldier project) after receiving an invitation from Dr. Abernathy (a nod to the pre-New 52 version of the character). Gaining superhuman powers, he attacked Superman but was defeated and arrested. He was released shortly afterwards by General Sam Lane who believed he was needed as a countermeasure to keep Superman in check. K-Man agreed under the condition that the General would help him locate his wife. It was revealed that Lex Luthor had played a major role in the K-Man's creation. Also (as revealed in flashback), he had stolen Kryptonite crystals from the government while being employed by them. His subsequent activities are unknown, but a version of him from the near future was a member of the Anti-Superman Army. He was seen alongside two people with similar powers (one equipped with Red another with Blue) as part of a group called the "K-Men". Alternate versions of Kryptonite Man In the
