"Green vs. White" from Martian Manhunter vol.2 #4 (DC, 1999) by John Ostrander and Tom Mandrake
He was a member of the early Justice League of America, of JL Detroit and the JLI, and there was the really awesome Jones/Barreto American Secrets mini-series that put J'Onn J'Onzz in the 50s at the height of McCarthyism, and then there was the strange-looking Mark Badger mini, but it would be the success of Morrison's JLA that would finally give the Martian Manhunter a shot at his own monthly series. I loved the premise Ostrander was working with, having J'Onn live his life in several secret identities, which made for a book that was more than just the "green Superman". And with the White Martians at the center of the first JLA arc, it meant J'Onn finally had villains of his own that weren't forgotten Silver Age comedy goons. Three years isn't a bad run, but I'm sure it could have gone longer. I wasn't around to read the '06-'07 8-issue mini-series, but I do know it didn't propel the character back into stardom.
