Geoff Johns (born 25 January 1973 in Detroit, Michigan) is an American comic book writer, best known for his work for DC Comics. In 2000, he succeeded James Robinson as David S. Goyer's co-writer on the title JSA. Also that year, Johns became the regular writer on the ongoing series The Flash. In 2003, he re-launched the DC comics title Teen Titans. Johns was responsible for the return of Hal Jordan in 2005 as the writer of the Green Lantern: Rebirth mini-series and subsequent Green Lantern ongoing title. Johns was also the writer of the DC Comics crossover event Infinite Crisis beginning in 2005, a sequel to 1985's Crisis on Infinite Earths. Following that comic book event, Johns was one of four writers - along with Mark Waid, Grant Morrison, and Greg Rucka - behind the landmark 2006-2007 weekly comic title 52. In 2006, Johns reunited with Richard Donner on the Superman title Action Comics, with Donner co-plotting the series with his former assistant. In August 2007 Johns and cowriter Jeff Katz re-launced the new Booster Gold series.
