Batman can huff and puff and roar around in his Bat-cycle and in his fucking Batmobile and jump off skyscrapers and yaddah-yaddah but he can’t kick Superman’s ass because he’s mortal and quite vulnerable while Superman is — hello? — a super-stud extra-terrestrial who’s faster than a speeding bullet, more powerful than a locomotive, can hurl an about-to-detonate atomic device into space and reverse the earth’s rotation if it comes to that. Superman can kick Batman’s ass while taking a nap or a bath or having a manicure so just shut up. The idea is fundamentally stupid.
