Robin (Tim Drake)
Here is something I posted a few days ago on the DCMB version:
Bruce quits being Batman. Is it because...
He finaly gets laid regularly, and he likes it a lot more than beating the crap out of thugs.
or
He used his money to pay all of Gotham's criminals to move to Metropolis.
or
At a meeting of Gotham's worst criminals, The Joker accidentally uses his gas on them, leaving him as the only living rogue. This catastrophe causes him to go so insane that he actually becomes sane, and no longer desires to kill people.
or
He has finally won his war on crime and turned Gotham into a utopia.
