Operation: Galactic Storm

"Operation: Galactic Storm" is a 19-part comic book crossover storyline which ran through Marvel Comics' Avengers related titles – The Avengers, Avengers West Coast, Captain America, Iron Man, Thor, Wonder Man, and Quasar – between March and May 1992. The storyline, which involves the Avengers intervening in an intergalactic war between the alien Kree and Shi'ar empires, is notable for reigniting the longstanding antagonism between Captain America and Iron Man, and its impact on the status quo for Marvel's alien empires, with the Shi'ar annexing the Kree Empire. The overarching plotline was devised by Mark Gruenwald, Bob Harras, and Fabian Nicieza, although each individual issue was written and drawn by the regular creative teams for each title.
