- You can't live for other people. You have to be true to yourself.
- — Larry Trainor src
Captain Lawrence "Larry" Trainor is a former Air Force test pilot, and a sad, introverted member of the Doom Patrol. He was involved in an accident that bound him to a being known as the "Negative Spirit" and made his body radioactive, making it necessary for him to wear lead-lined bandages at all times, and accept the power inside him, as well as his closeted homosexuality, as a gift, not a curse.
Larry Trainor was born around 1927 to Gerald and Debbie Trainor in North Dakota. One day at school in 1935, he was caught "playing doctor" with another boy, and the principal reported him to his parents for homosexual activity. Though Gerald refused to believe the claim, saying the principal simply had a grudge against Larry, Debbie knew it was true and feared for the family's reputation if the community found out.
As an adult, Larry became a test pilot for the United States Air Force. He suppressed his homosexuality and married a woman named Sheryl. Together, they had two sons - Paul and Gary. However, Larry couldn't suppress his feelings completely and began cheating on Sheryl with another Air Force pilot named John Bowers.
Larry's sons idolized him and his work as a pilot. Even though Larry tried to connect with his sons, he couldn't help but be overly critical of them sometimes, at one point creating a lasting memory in which Larry tore apart a cardboard plane that his son Gary made for him right in front of the boy because Gary had assembled it incorrectly.
In 1961, Larry was selected for an experimental X-15 flight test to the Earth's stratosphere. His family was very proud of him but worried about the dangers that inherently came with piloting an experimental vehicle. Larry assured them it was safe, while in reality, a scientist named Niles Caulder mapped out a dangerous path for his vessel, all to further his own experiments. Larry also spoke with John during the weeks leading up to the flight, and John insisted they leave Larry's family and the Air Force, living free out on the open road. He was initially against this idea, but eventually, Larry caved in and agreed to decide between his family and John once the flight was over.
On the day of the mission, Larry took off and passed through a cloud of cosmic radiation, merging him with an entity called a "negative spirit". The process caused Larry to lose his senses and the vehicle to fall. Thanks to the new powers he acquired from the negative spirit, Larry managed to survive the fall, but the explosion burned his entire body. He also couldn't control the radiation he now produced. The government rushed in to cover up the accident, and Larry was rushed to a radiation-proof hospital room. Sheryl came to see him and told him she was leaving with Paul and Gary. Larry protested, but Sheryl was gone before he could say much. John came to see Larry and tell him he'd stand with him in his darkest hour, but the bitter and angry state Larry was in compelled him to order John away, to which he complied, leaving Larry all alone in a new world of unknown nightmares.
The Ant Farm
Larry was detained by the Bureau of Normalcy within their facility known as the Ant Farm and given a bulky suit to contain his radiation. He spent years in isolation in a cell as the Bureau studied his transformation. The government covered up Larry's accident, claiming that he had died in the plane's explosion. His family was devastated, but his wife swore she knew the truth - that he was still alive. As the years went by, Sheryl's conspiracy theories rubbed off on their son Gary, who dedicated the rest of his life to finding out what really happened to his father. Paul, wanting to honor their father's alleged death rather than dwell on the mystery, grew up and joined the military like his father.
Meanwhile, Larry himself was in constant pain, with the Bureau members attempting to weaponize him and the Negative Spirit within him for military use. Pained and scared, he began to develop a very introverted nature, even pushing away Flex Mentallo, a fellow prisoner in his neighboring cell who could have possibly helped him.
New Life at Doom Manor
Eventually in 1966, Niles Caulder rescued Larry from the Ant Farm, and offered him a home in his mansion in Ohio. Larry accepted, still confined to his bulky suit to contain the radiation. There, Larry was introduced to Rita Farr, a former Hollywood actress who was made physically and molecularly unstable by the Chief's experiments. Although it was slow to start, the two became close friends. As a "welcome home" present, Caulder gifted Larry a set of radiation-proof bandages and goggles to wear, which proved more flexible than his current costume.
For decades, Larry lived at Doom Manor, dwelling on the life he lost and the time that had passed him by. He took up gardening and kept to himself. At some point, he met Jane, another one of Caulder's experiments with at least sixty-four unique personalities, each with their own unique metahuman ability. Jane and Larry disliked each other a great deal, and Larry naturally stayed out of everyone's way, mainly wanting to be alone. Jane returned to the Manor a few more times before vanishing for several decades.
In 1988, the Chief brought a new guest to their home - Cliff Steele, a racecar driver who had lost his body in a car accident and had his brain placed into a robot body. While the Chief worked on Cliff's body, Larry was informed his wife passed away of cancer, something he didn't feel very sorry about.
When Cliff's body was completed and activated in 1995, Larry was tasked with monitoring Cliff's recovery, becoming one of his first friends in the manor, as the new robot-man learned how to walk in his body for the first time. Once Cliff became comfortable in his new body, he went to the Chief and told him he was going to find his family, but the Chief revealed to him that they were killed in the same accident that destroyed his body. Devastated, Cliff shut himself in his room for several years, contemplating his mistakes and his family's demise, until 2002, when Larry decided he could use some help and gifted him a toy race car track. Cliff left it alone for six more years, then finally decided to stop brooding and try to move on. He constructed Larry's kind gift to him, one piece at a time, adding onto it constantly, until in 2019, he even allowed Larry and Rita to play with it and marvel it. At this point in time, none of Caulder's guinea pigs knew about his involvement in their "accidents".
In 2019, Jane returned to the Manor to live there once again and met Cliff for the first time. As they hit it off, Larry steered clear of Jane even more than the others, given his rather closed off attitude, as she stayed with them for the next few weeks.
