[Crazy Jetty]

@ Greenskar
I actually don't entirely disagree with you. In fact, mine was the first responce in this thread, and I did say when it comes to the Business aspect, Tony has the upper hand.

Dispite your very well thought out reasons, I just think you're underselling Bruce and co.
It's true that since no one knows Bruce is the bat, they can't wave Batman's tech as what they're capable. They can't say "Here's the JLA Watchtower, we're responcible for the tech behind this. Here's the Batwing, the world's stealthiest jet." since these are covertactivities.
But one thing so many people overlook, is that most of Batman's tech is based on Waynetech prototypes and designs. They don't have exactly what Batman has, but they do have simular tech in their files.
But do I think they'd win a contract over Stark? Maybe. Depending on the contract. Some they have an upperhand, as Waynetech is far more branching than Stark. But in the main kind of contract most people are talking about (Defence technology I'll say, because neither company is interested in arming anyone with guns), I do think Stark has the upper hand. Largely because he has far more pizzaz, and his company's greatest achievements are on display.
But ultimately, as far as tech goes, almost all of Batman's gear is based on existing Waynetech prototypes and blueprints. While they can't say "Here's the Batplane!" They can say "We have a prototype of a 6th Generation stealth jet." I think would indeed show off stuff like that to impress whomever they're trying to impress.

I also agree that I don't think Wayne, Fox, or Waynetech would do anything so super shadey just to win a contract over Stark Industries, as has been suggested.

And more in general, for those who say there's no way Batman could realistically take Ironman, and that Batman has been overinflated and is now a Mary Sue?
I disagree. Here's why:
Batman's true "superpower" is he has one of the steepest and fastest learning curves in all comics. Something everyone tends to forget, Batman usually loses in his first few encounters with a new foe.
Hell, quite often his old familier foes get the upperhand over him, in confrontations.
So the first time Batman and Ironman butted heads, of course Batman would lose. Batman has absolutely no hope. But, Tony doesn't kill, and I don't think there's absolutely any way Ironman has to capture and contain Batman that Bruce couldn't get out of. So it's a given that Batman would get away from their encounter.
But this is indeed where Ironman's connection to Stark would be a disadvantage. It means researching him would be easy. (Assuming this is a continuity where Ironman's identity is still secret) Bruce would eventually put two and two together and figure out his identity. And then he'd start trying to figure out the chinks in the Ironman armor. It may take a few tries, but I think Batman would eventually have no problem overcoming Tony's armor.

Ultimately, I think it would end with the two coming to an understanding. Basically that Batman thinks Ironman should get out of Gotham.

If this were a Civil War type senerio, then I think Batman would be Tony's most dangerous foe. Batman would employ his full Bat Family, and be in total ninja mode.
