We don't have to do anything weird with the deaths of the Doom Patrol. It's since become cannon that the reason his ship crashed is specifically because it passed through the energy of the negative energy entity which claimed him as a host, and that absolutely works. To begin, of course we can just use Larry Trainor's original story. That's amost always the case with the best Grant Morrison characters, they are just such a great hodgepodge of wild ideas that we can gently disassemble and choose the best parts of them to incorperate into our version. There is a lot of fun stuff we can do with Negative Man. Later versions of the Doom Patrol would bring back versions of Larry Trainer in one form or another, but this really is the ideal resolution of their story, and we're going to us this as a major story in the timeline of or Doom Patrol. Our Negative Man Story which Rebis chose to make their new home. Morrison's story grew to an amazing climax, with the team finding it's way to the fantasy paradise of Danny the World. Their whole purpose was to continue their own lifecycle, which involved them leaving to mate with themself and to grow a new body. They were now precognative, psychic, capable of dimentional travel and essentially immortal.

They were just an absolutely fascinating character, depicted as observing humanity as an outsider with their powers now seeming far more advanced. Knowing what we now know about Grant Morrison, that they have since come out as non-binary, I have to say I really love that Rebis was such a huge part of this classic, incredibly high profile comic. It appears to Larry and attacks him, merging itself with him, and with his doctor Eleanor Poole, to become a new composite entity that is notably intersex, taking the name Rebis. The Negative energy body left Valentia, revealing itself to be a sentient entity named Mercurius with it's own sense of morality. Eventually he was fully cured, just in time for Grant Morrison to take over the book. Very quickly, it was revealed that Larry had survived, and was still forced to keep his body wrapped in it's bandages, and soon was a sort of pseudo antagonist for Valentia.
NEGATIVE MAN LARRY TRAINER SERIES
When the new Doom Patrol series started in 1987, at first it was understood that Larry was dead, and the negative entiry that had been his powers was now bonded with a new character, Valentia Vostok, a former russian cosmonaut and the new Negative Woman. He and the rest of the Doom Patrol were apparently killed in an explosion in the final issue of Doom Patrol. His soul self powers allowed him to take a wide variety of utility roles on a superhero team, but they aren't the sort of powers that provide any sort of wish fulfillment. Larry was an adventurer with a tragic past, having essentially become a monster. He is able to project a mysterious negative energy body from himself, leaving his physical body inert and vulnerable, but crucially can only do so for 60 seconds, or he will die on the spot. A former test pilot who lost control of his plane when it was bombarded with strange radiation (the Doom Patrol was an almost direct pastiche of the Fantastic Four), leaving him with an irradiated body that has to be wrapped in special treated bandages. Negative Man was one of the founding members of the Doom Patrol in 1963's My Greatest Adventure #80.
