He's straight, so no. ZING!
But seriously, differences? Well, he's Arabic/Chinese (and half-white, I guess), and was raised by assassins. Also, he's a violent little bastard, which means Batman has to reign him in so he won't kill people.
Supposedly he'll become the new (and demonic) Batman in the distant future.
In other words, it's complicated. Also, Batman recently got killed by the God of Evil resulting in his soul getting blasted back in time to caveman days, where's he's reincarnated as a caveman with a giant dead bat on his head.
Or something, I haven't actually read it. But I'm not kidding about any of the above look it up if you don't beilive me.
