Too late. Yamcha beat him to the punch line.
New 52 Martian Manhuner manhandled all the Justice League including Superman... he has a pretty good shot.
Not exactly that impressive considering 6/7 of the justice league got the nerf stick to the face quite hard. Only one that's had any impressive feats is supes.
I'm not really sure how they've all been that nerfed considering the only one I've seen it from is Green Lantern.
That flash has by far been the most useless member of JLA thus far which is funny considering pre-52 he was the most hax and one of the reasons the new-52 happened. Aquaman got a durability nerf, strength nerf, his TP isn't as good as well. Haven't seen anything from WW but i'd assume she got the nerf stick too. And supes seems to not have changed for the worse but rather got stronger. This is at least from my point of view, all of the their pre-52 counter parts save superman would beat them in a fight just based off feats. Especially flash.
