Larry Trainor could release a strange being called Negative Man from his body; it was composed of an unknown form of energy. It took the form of a man, had no individual consciousness of its own, and was subject to Trainor's commands. Trainor was physically weakened whenever the being left his body (all physical stats change to Feeble while Negative Man is free), and he was in danger of death if Negative Man was out of his body for longer than sixty seconds. The being had the following abilities:
HARD RADIATION EMISSION:
The Doom Patrol
Test pilot Larry Trainor was flying an experimental rocket plane when its controls jammed, causing it to fly uncontrollably into intensive radiation in outer space. Unconscious, Trainor drifted through the radiation for hours until his plane finally fell toward Earth. Trainor revived just in time to make an emergency landing, but his body was now aglow with radiation, and his skeleton was visible through his skin.
Trainor saw a search plane spot him and descend, but only one of its wheels emerged. As Trainor wished he could save the plane from crashing, a strange energy being emerged from his body, flew up to the plane, and pulled down the remaining landing gear.
Eventually, Trainor's body was completely wrapped in radiation-proof plastic bandages invented by Dr. Niles Caulder. Trainor tried to lead a normal life, but was shunned. He was offered a job by one Dr. Drew, whom Trainor nicknamed "Dr. Death." Dr. Death intended to conquer Earth, but Trainor thwarted him. Later, Dr. Death trapped Trainor in a lead chamber and prepared to take over America. Caulder enabled Trainor to escape and defeat Dr. Death. Subsequently, Caulder invited Trainor to join his new team of super-heroes, the Doom Patrol. Trainor became known as Negative Man, the name he more specifically gave to the energy being whom he could command to emerge from his body and do his bidding.
After many adventures, Trainor and his three fellow Patrol members were captured by their foe Madame Rouge and her ally Captain Zahl. Zahl told the Patrol that unless they allowed themselves to be killed, he would blow up a small village and its inhabitants. The four Doom Patrol members courageously agreed to sacrifice their lives to save the villagers, and Zahl blew up the land where the Patrol was standing, killing them all.
