I.Q. (Ira Quimby) is a fictional character appearing in American comic books published by DC Comics.
Ira Quimby is a small-time crook who is accidentally exposed to the radiation from a rock that had been irradiated by a Zeta Beam, transforming him into a metahuman with superhuman intelligence. Dubbing himself I.Q., he uses his new intellect to plan a series of jewelry heists. I.Q.'s heightened intelligence turns out to short-lived, but re-exposure to the rock restores it. Hawkman tracks down I.Q. by analyzing traces of the rock, and arrests I.Q. and his gang.
In Hawkman #7 (April 1965), the imprisoned I.Q. discovers that his heightened intelligence returns whenever he is exposed to sunlight. He is able to create an invisibility device out of common items and escape from jail, and resume his life of crime. In subsequent stories I.Q. faces the Justice League of America,[1] Superman and the Metal Men,[2] Batman,[3] the Teen Titans,[4] the Atom (Ray Palmer),[5] and the Elongated Man.[6]
During the Infinite Crisis storyline, I.Q. popped up as a member of Alexander Luthor Jr.'s Secret Society of Super Villains.
In 52 Week 23, I.Q. is revealed as one of the "mad scientists" kidnapped by Chang Tzu and Intergang, and taken to Oolong Island to become a member of the Science Squad. When Black Adam attacks Oolong Island, he remained collected and rallies his fellow mad scientists to successfully defeat Adam.[7] He subsequently becomes the head of projects on the island.[8]
In , it was revealed that Quimby was working with the supervillain Prometheus, who repaid him by causing his brain to revert to an infantile state.[9]
He has since been seen in Doom Patrol, working for Veronica Cale on Oolong Island. Quimby's appearances in this title have yet to explain the recovery of his faculties, but they chronologically follow Cry for Justice (as seen in the Justice League of America title which has the team dealing with the aftermath of CfJ leading into Blackest Night).
