Maybe Batman is a robot created by the Gothem government to fight crime. It would explain alot of his super human strength and powers. After all he didn't get bitten by a bat or a vampire, unless he was a vampire robot - like an IRS tax worker. I once talked on the phone for twenty minutes with a robot without knowing it. We laughed and reminisced and carried on a real conversation. He even lied when I asked him if he was a robot, to which the woman who he passed me to said, 'yea, he's a robot.'
He's a comic book character. He's exactly what the comics say he is.
