'Doom Patrol': With a name like Negative Man, you'd be surprised that he's actually a positive and upbeat character
Ever since 'Doom Patrol' was created in the early '60s by Arnold Drake, Bob Haney, and artist Bruno Premiani, we've seen this team of super-powered misfits in multiple incarnations over the past decades, and Negative Man, being one of the founding members of the 'Doom Patrol' team has gone through similar reincarnations and rebirths, but the most well-known Negative Man by far is Larry Trainor.
Negative Man is one of the founding members of 'Doom Patrol', and like many of the other team members, his story is also a rather sad one. Larry Trainor was an ace test pilot, who got accidentally exposed (as most to-be superheroes do) to a radioactive field in the atmosphere. After coming in contact with the radioactive field, his body had become highly radioactive (hence the whole mummified look), while simultaneously giving him a new ability as well.
