Flex Mentallo is a superhero who employs the use of his strange power of "Muscle Mystery". He works closely with the Doom Patrol and leads its trainee team Flex Force.

After being kidnapped by the Men from N.O.W.H.E.R.E., Mentallo was subjected to a form of torture that, when he escaped, rendered him unable to access his Muscle Mystery anymore. Only after watching the Doom Patrol fight a splinter cell of the Men from N.O.W.H.E.R.E. did Mentallo's powers return to him. After that, he started waiting inside the mysterious, sentient location Dannyland, preparing for when the Doom Patrol would regroup and continue their mission.[1]

After Superman is framed and rendered comatose, Flex Mentallo joined the group of heroes heading towards Mars to confront their mysterious enemy. The heroes meet and engage Doctor Manhattan, but they are easily defeated.[2]

Flex later was still part of the Doom Patrol when they relocated to a new Headquarters known as "The Shelter," a bunker hidden under a Kansas farmhouse, where he runs a gym for the many Metahumans that have taken refuge with the Doom Patrol. He also has entered a romantic relationship with his teammate Rita Farr.[3] Mentallo gathered a group of his metahuman trainees into Flex Force, a junior team to the Doom Patrol. He pitted them against the Patrol in a game of capture-the-flag, which, though lost to the senior team, provided an impressive demonstration of their abilities. Mentallo was then forced to lead his team into action for the first time, fighting alongside the Doom Patrol to defend the Shelter from the attacking Brotherhood of Evil.[4]



  • Leadership: Flex Mentallo gathered and trained the metahuman rescues of Flex Force into an effective team.[4]
