Lawrence Trainor was a test pilot with the United States Air Force. Whilst experimenting with a space plane called K-2F, he was exposed to cosmic radiation after the plane went higher than it was supposed too. The radiation left Larry with transparent skin as well as leaving him radioactive. During his stay in a hospital, he met Dr. Niles Caulder. Caulder gave Larry specially treated bandages that blocked the radiation. Caulder also told Larry that he now had an energy being in him called the Negative Man - and that he could let the being loose any time he wanted. Following the shuttle's crash, Larry had let it go, making him a special interest case for the government.
Negative Man was created by writers Arnold Drake, Bob Haney and artist Bruno Premiani. His first appearance was in My Greatest Adventure #80 published June 1963. This cover is centered around Negative Man.
Silver Age: Earth-One
Following two weeks of experimentation, Larry was released. Finding fitting back into the world difficult due to his disfigurement, Larry withdrew and began experimenting with the Negative Man. This is when he found that if he did not return to his body in sixty seconds, he would die. During this time period, bandages kept being delivered to him, regardless of where he was staying. During this time, Caulder approaches him to join the Doom Patrol.
Modern Age: New Earth
After the Crisis on Infinite Earths, much of Larry history was not change. Larry ultimately came back from the dead. While the Chief originally told Larry that he had cloned a body from Larry's original body, it turned out that Larry Trainor had died for good. The body Negative Man now inhabited was a comatose man named Thomas Munroe, who had no family, few friends and no brain activity. The Chief had added enough of Larry's DNA to Munroe's similar DNA to make it seem like a clone.
Larry's history is rebooted and in this new reality Larry returns in yet another body. This time a man named Phillip Sloan once again doctored by the Chief. After about two months, Robotman contacts Larry to join a new incarnation of the Doom Patrol. Larry declined until Robotman revealed that Rita had been resurrected as well. Both Larry and Cliff played along with Rita's idea that she had survived the Codsville incident.
During the Infinite Crisis, Larry regain all his old memories. Negative Man is currently a member of the Doom Patrol, based on Oolong Island. He has since learned to partially unleash the Negative Entity, granting him its powers without the time limit. During the Blackest Night, he found himself up against the Black Lantern Valentina Vostok. When their Negative entities met, it temporarily created an entity similar to Rebis, which destroyed the Black Lantern ring. Larry maintains an antagonistic friendship with Robotman, a close friendship with Rita, and a bizarre belief that pelicans are stalking him that may yet pay off.
