TheThinker is the name of fivesupervillains appearing inAmerican comic books published byDC Comics.
The first incarnation,Clifford DeVoe, is an enemy ofJay Garrick. The second,Clifford Carmichael, is an enemy ofFirestorm. The third,Desmond Carter, is an enemy ofBatman. The fourth, anA.I. version of the Thinker, is an enemy of theJustice Society of America. An unidentified incarnation of Thinker, introduced in theNew 52, is an enemy of theSuicide Squad.
The character has been adapted from the comics into various forms of media, including television series and feature films. DeVoe made his live-action debut inThe Flash, portrayed primarily byNeil Sandilands. In theDCEU,Peter Capaldi portrayedGaius Grieves, an original variation of the Thinker inThe Suicide Squad (2021)
The Clifford DeVoe incarnation of Thinker first appeared inAll-Flash #12 (Fall 1943) and was created byGardner Fox and Everett E. Hibbard.[1]
In October 1947, the Thinker was one of the six original members of the Injustice Society, who began battling theJustice Society of America inAll Star Comics #37 (Oct 1947).[2]
The Cliff Carmichael incarnation of Thinker first appeared inFirestorm #1 (1978) and was created byGerry Conway andAl Milgrom.[3]
Conway recounted, "My original notion onFirestorm was to do a book that would be DC's complement toSpider-Man, in a sense. We would have a young adolescent male who gets superpowers and doesn't know quite what to do with them. My flip on it was that rather than being the science geek who was being picked upon by the jock, my hero would actually be the jock who was picked on by the geek, and that was going to be Cliff Carmichael's role."[3]
InThe Fury of Firestorm the Nuclear Man #50, the strap onRonnie Raymond's football helmet is cut, and in the following issues Carmichael is suspected of the crime. Though Conway later said that he must have intended to ultimately reveal someone else as the culprit,John Ostrander took over as the series' writer and had Carmichael confess to cutting the strap.[3] InFirestorm #99, Carmichael became the Thinker as part of a genre-wide trend in which civilian cast members were almost eliminated from superhero comics.[3]

Clifford DeVoe is a failedlawyer who bitterly ended his career in 1933. Realizing that many of the criminals he had encounter have the skills but not the brains to ruleGotham City's underworld, he starts a new career as the brain behind small-time villains. As the Thinker, he is defeated by the originalFlash/Jay Garrick, his most recurrent foe. DeVore wields the "Thinking Cap", a metal hat that can project mental force.
The Thinker is a member of theInjustice Society, leading an army of prison escapees like the other members.[4] In Plateau City, the police nab a shabbily dressed man who is trying to shoot the governor. They discover that this man is a dead ringer for the governor and also claims to be the real governor. The Flash arrives on the scene to overhear this, but moves on to confront the hoodlums attacking the city. The Thinker appears on the scene, firing a ray at the Crimson Comet, causing him to gain weight and crash through a roof. Recovering, the Flash speeds over to the governor's mansion, only to overhear the governor ordering all police forces to surrender. Flash enters his office and discovers the governor to be a dummy/machine, which flees through an open door. Flash attempts to warn the police that a phony governor put out the message, but the Thinker shows up and tells the Flash that he is speaking into a dead mic, then snares him with invisible wires.
The Thinker appears as a judge in the 'trial' of the JSA, but is revealed asGreen Lantern in disguise, having captured the real Thinker after escapingBrain Wave. This leads to the Injustice Society's defeat. Together with theFiddler and theShade, the Thinker is the man behind the decades-long "abduction" ofKeystone City and the original Flash.[5] His "suspended animation-time" in Keystone keeps the Thinker young over the years, and he continues his criminal career in modern times.
DeVoe accepts a mission withTask Force X in exchange for a full pardon.[6] Although he is seemingly killed byWeasel during this mission, he turned up alive soon after, only to be dying from cancer due to the cap.[7]
In 2016, DC Comics implemented a relaunch of its books called "DC Rebirth" which restored its continuity to a form much as it was prior to "The New 52" reboot. Thinker is depicted as a former district attorney.[8]

Clifford Carmichael is an intellectual bully and the rival ofRonnie Raymond (one half ofFirestorm) at Bradley High and later at Vandemeer University. Cliff viewed Ronnie as a rival due to his popularity. He torments 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. Cliff's cousin Hugo Hammer accidentally takes Ronnie's helmet, causing his neck to be broken during a football game.[9]
Wracked with guilt after accidentally paralyzing Hugo, Cliff is admitted into amental institution.

After an anti-American dictatorship takes over the Corto Maltesean government and kills his scientific staff with the intention of weaponizing Starro in the present, Grieves sides with them to save himself by claiming that only he can control the creature. However, he is captured by the Suicide Squad, whomAmanda Waller sent to destroy Project Starfish and bury its U.S. ties, and forced to help them infiltrate Jötunheim until they accidentally release Starro, who kills Grieves in retaliation for experimenting on it.
