If Batman had armor laced with kryptonite he'd beat Superman like a redheaded stepchild. Assertion of stupid premise debunked.
It's Hulk vs Superman that I want to see. That and a catfight between Catwoman and Emma Peel where their leather suits get frayed and start to peel off. " I'd buy that for a dollar!"
Superman could just drop a mountain on batmans ass.
Or pick up batman while he’s inside his lair and launch it into space.
Batman would have to get he kryptonite close enough to to hurt superman.
Like I said, with a little common sense, the batman vs superman premise is stupid. Batman is a chump. I don’t care how intelligent he is.
