9. Sleeping With Talia al Ghul
...was a really bad decision. In every version of the Batman mythos,
ever. Look Bruce, I get it -- it was the '70s, during your "bare chested love God" phase. You were a playboy on the make, and along comes the daughter of a powerful warlord with aims similar to your own (well, up to a point...), and she's as skilled in combat as you are, and she looks like
that...and she's got the hots for you. And when Talia was the Dennis O'Neil creation -- a (frankly) somewhat shallow male fantasy, torn between her love for both Batman and his arch nemesis, her father, but mostly there to throw herself at Bruce Wayne every chance she got -- having sex with her, even siring a child with her, was somewhat excusable. But then came Grant Morrison. And sleeping with Talia al Ghul suddenly became the worst one night stand any man has ever had in the history of sex.
Under Morrison's pen, Talia was (rather logically, it must be said) transformed from a kind of idealized Bond-girl romance for the Bat into a psychologically twisted woman, almost shorn of human feeling, so
convinced that Batman will rule the world by her side that when he rejects her crazy offer, something
snaps. No longer does Talia and Batman's union result in a secret child put up for adoption; now their son, Damian, is a highly skilled half pint assassin, and the battle for his soul will literally lead to
armed conflict, one that has in the last six months or so nearly reduced Gotham to rubble in the pages of Batman Incorporated. So...yeah. Maybe you should've payed slightly closer attention in sex ed class, Bruce, and used protection. And on the subject of sex...
