during this mission, he turned up alive soon after, only to be dying from cancer due to the cap. His former foe, the original Flash, attempted to save him with the Thinking Cap, but DeVoe refused and preferred to rest in peace. In DC Rebirth, Thinker is depicted as a former district attorney of Keystone City back in the 1940s and fought Jay Garrick. After being briefly told by Eobard Thawne that everyone will forget him, Jay throws his helmet towards Thinker to knock him out and then takes down Thinker's henchmen. Cliff Carmichael Clifford Carmichael was an intellectual bully and the rival of Ronnie Raymond (one half of Firestorm) at Bradley High and later at Vandemeer University. Cliff viewed Ronnie as a rival due to Ronnie's instant popularity. Cliff tormented Ronnie throughout his high school career and later at Vandemeer University. It was at Vandemeer that Cliff's pranks turned sinister, as he cut the helmet strap on Ronnie's football helmet, hoping to get him injured. Hugo Hammer, Cliff's cousin, accidentally took Ronnie's helmet and during a football game, his neck was broken. Wracked with guilt after accidentally paralyzing his cousin, he was admitted into a mental institution. For some reason, scientists started an experiment with the now-abandoned "Thinking Cap" of the original Thinker (who was believed dead at the time) and used Carmichael as a guinea pig. Cliff used the cap to analyze the device and improve on its design. Implanting microchip versions of the helmet into his own brain, Cliff became a "cyberpunk maniac" with metahuman powers. As the new Thinker, he was drafted into the Suicide Squad after he tried to kill Oracle and Amanda Waller. After several missions, he betrayed them for the villainous Cabal. He has since resurfaced as a foe of Jason Rusch, the new Firestorm. When Killer Frost discovered that the consciousness of Raymond, the previous Firestorm, existed within Rusch, Thinker exploited a new opportunity to antagonize an old foe. Technologically dominating the minds of Multiplex and Typhoon, he battled Firestorm, ultimately forcing the dissolution of the Raymond persona. Motivated by his predecessor's final words of encouragement, Rusch dissolved the enhancements in Carmichael's brain, leaving him in a comatose state. During the 2005–2006 "Infinite Crisis" storyline, Cliff appears as a member of Alexander Luthor, Jr.'s Secret Society of Super Villains. With John Ostrander's revival of the Suicide Squad in a 2007-2008 miniseries, Cliff
