i'd say , JLA would win if they also include both all inactive & resigned member in both party.
most people think that GL kyle would be easily beaten down, but the fact is - i'm sorry to say , he could defeated & prevent himself from telepathic power coz the rings he wear is not those crappy kinds but the powerfull weapon in the universe.for kyle , he always have a chance to defeat phoenix or magneto of prof. x
coz he can protect telephatic powers by using his ring as a shield and as for magneto , all he can took from gl is his mask coz his mask coz his mask is a metal plate but not his power and for sure gl kyle is not that easily to be defeated is not just because he's gl but a creative artist who can imagined how to survive.
i guess no one mention about J'onn J'onnz,i say he's a martian and also have the psychic ability, but don't look down on this guy coz he's ain't a human & he's maybe even stronger than anyone would expect.
batman fighting wolvie, batman got the chance to beat him down coz in this match is not just about skills but also about brains & brauns (sorry if the spelling is wrong). if battie knows wolvie is coming, he would win but , there's a but , wolvie is unpredictable. i say this match would be a draw match.
about aquaman, it's hard to give an explaination coz i don't have the source for the guy, but flash, his speed is strenght but i don't know about his mind.
to know more about gl abilities, just go search for one.
