Omega VisionIn a comic Batman would win but consider that Martian Manhunter can probably mind rape all of them save Wonder Woman without actually being close to them and then its just him vs Wonder Woman and I'd say he wins.
They're pretty close normally, but fully geared up? I think WW stomps him (10x strength. Soul-raping lasso. Enchanted armor. Sword of Hephaestus).
Something else in her favor is that in bloodlust-evil mode, she's not only physically much more dangerous for the kill, the Lasso can also be used to turn the others against each other. Make them go berserk and have Batman blame Superman for his parents being shot or J'onn blame the others for the destruction of Mars. It's pretty sick.

I don't think he could do it in hand to hand, but it's relatively easy to set a trap for Aquaman/make a device that'd kill him, when compared to the others.
