The character was created by Bob Haney, Arnold Drake, and Bruno Premiani and made his first appearance in My Greatest Adventure #80 (June 1963).

The Larry Trainor incarnation of Negative Man first appeared in My Greatest Adventure #80 and was created by Bob Haney, Arnold Drake, and Bruno Premiani.

[2] Drake recalled: I left [editor Murray Boltinoff's] office and bumped into Bob Haney in the hall.

[3]The original Negative Man, Larry Trainor, is a founding member of the Doom Patrol, along with Elasti-Girl, Robotman, and Chief.

After his accident, Trainor is forced to wear specially treated bandages over his entire body to protect others from his radioactivity.

He later breaks Reactron out of Belle Reve Penitentiary and after fitting him with a regulator, uses him to successfully draw the negative being out of Vostok.

[6] During an encounter with Garguax, the negative being is disrupted and returns to Vostok, but saves Trainor and in the process heals him completely, removing all radioactivity from his body.

[8] Rebis temporarily leaves the Doom Patrol to complete its life cycle, which involves working through the trauma caused by the death of Trainor and Poole's identities.

In 2004, the Doom Patrol was rebooted in a new series written by John Byrne following Superboy-Prime's alterations to reality during Infinite Crisis.

When Larry Trainor was accidentally sent to a field of cosmic radiation while testing out an experimental jet into the stratosphere and crash landed back on Earth, his physiology had been changed permanently and requires the Chief's lead-lined bandages so he could operate in human society.

In this form, he can fly at supersonic speeds, phase through solid objects, and absorb thermal energy to convert it into an explosive discharge or generate waves of intense heat.
