Thanks for the input, everybody! I'm fascinated by all of your various viewpoints. My question came about as a side-effect of something that popped into my mind recently: If they were gay or bi, Batman and Iron Man would make a great couple. In my opinion. I mean, I believe that each needs a lot more love in his life, and I likewise believe that they'd complement each other, you know? Batman's focus and determination would have a positive effect on Iron Man's psyche, while Iron Man's fire and spontaneity would have a positive effect on Batman's psyche. Their strengths would strengthen; their weaknesses would weaken. The irresistible force and the immovable object would become one. Perhaps together they could achieve the inner calm which they have both sought for so long...
Besides, if Batman and Iron Man are an item I myself might finally be able to score that threesome with Catwoman and Pepper Potts. I'll catch 'em on the REBOUND, baby! (Unfortunately for me, it appears that Brandy Clark is still utterly devoted to Rom, Spaceknight. Perhaps I can convince Rom to fall for a toaster or something?)
With concern to the question itself... well, I rather concluded that the kid -- the Iron Bat? -- would end up in the DC Universe. I'm inclined to agree that between Batman and Iron Man Batman is the more paternal of the two. I mean, at the very least he does have a habit of adopting orphans; can you imagine Iron Man encouraging a little chum to follow him around? Heck, I wouldn't put it past Batman to invent what appears to be an indestructible Batrubber but subconsciously incorporate into it a feature that causes it to break at just the right instant, you know?
"Oh, my God! I'm so sorry! I don't know how
it could have happened. I could have sworn
that it was indestructible. I mean, those ribs aren't there just for your pleasure -- they provide structural integrity, too! I'll call Lucius later and ask him his opinion. I really think that we should keep the kid, though, O.K.? I'm sure that you're pregnant because by pure chance I actually happen to be wearing my Batspermcountincreaser at this very moment. I'll even raise him! He can live here at the manor! You won't mind if I dress him in little tights, will you? ALFRED? ALFRED? WHERE ARE THOSE LITTLE TIGHTS THAT I KNITTED?"
Now, as for Bizarro and the Hulk...Spel
So softly a superman sighs...
