It's a name. ONE name. It could be Alexander Batman (Last name here). Just because he names HIS child what HE wants to doesn't mean that his child has to go by Batman. Think about the names that people have out there...I mean come on. I think batman is so much better than some of the names I have heard in my life (Lemonjello((Pronounced Lay-mon-ge-lo)), Orangejello(Pronounced Or-ang-je-lo) <--yes, these are peoples names, named because the mother ate a lot of jello and liked the way they sounded.) Sound stupid now?
And just think about how much fun it would be to say "I am batman"!
