a nuclear missile. Really ? against someone who can simply outrun the point blank explosion with Flash powers, or simply shrug it off because he has Superman invulnerability, or just protect himself because he has the green lantern ring ? just to name a few of the ways he can avoid such attack ?
do these authors realize that to make Batman the retarded walking "deus ex machina" they want him to be they go against every single other DC character? to the point they seem to completely loose their status of superbeings?
There is no foe that the JLA spends more time training against than Amazo, because he scares the crap out of them. Batman spends even more time prepping against Amazo. When they fought, Batman put putty over Amazo's eyes, knowing that he'd use Superman's heat vision to burn through them. Only they were laced with C4, so he exploded his own eyes. He was disoriented from having no eyes (so there go his GL powers), so then Batman tells Nightwing that he's studied Amazo's design, and that there was a design flaw in his knees, so they disable his ability to walk (try hopping at superspeed). Then, for the coup de grace, he launches a nuclear missile from the Batmobile, and the fight is over. Yes, Batman keeps a nuclear payload handy. Had Amazo taken him serious, he would have a chance.
No one ever takes Batman serious in a fight (Superman, Amazo, Darkseid) because he has no superpowers, and then he just MacGuver's them to a KO. This is why Batman wins, and consequently, loses to normal powered beings that he hasn't prepared for. Time and time again, Batman encounters a superpowered being, and he's like OK, I've been studying this guy's powers years before I met him, and have 15 ways to neutralize him. Think about it, Darkseid is the Thanos of the DC Universe, and only two beings have defeated him in man to man combat, Superman and Batman. Superman's beaten him by brute strength, Batman's beaten him because Darkseid sees Batman as a flea (and he's not). Twice now, Batman's beaten Darkseid through preparation (one time he laced the fire pits of Apocalypse, threatening to destroy the planet, the other time, he killed him with a God Killer bullet). Both times, Darkseid didn't really take him serious until it was too late.
