for Marvel Comics, Johns oversaw the re-launch of Hawkman and 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 the writer of the Infinite Crisis crossover limited series (December 2005 – June 2006), a sequel to 1985's Crisis on Infinite Earths. Following this, Johns was one of four writers, with Mark Waid, Grant Morrison, and Greg Rucka, on the 2006–2007 weekly series 52. In 2006, Johns and Kurt Busiek co-wrote the "Up, Up and Away!" story arc in Superman and Action Comics. He then reunited with Richard Donner on the "Last Son" storyline in Action Comics with Donner co-plotting the series with his former assistant. The Justice Society of America series by Johns and artist Dale Eaglesham began in February 2007 and six months later, he and Jeff Katz launched the new Booster Gold series.
