Iron-Man(Tony Stark) vs Batman(Bruce Wayne)
This is Robert Downy Jr Iron-Man vs Anthology Batman, as in the one from Batman, Batman Returns, Batman Forever, and Batman and Robin.
So here is the set up...
After the events of Iron-Man. Stark begins to her rumors about masked vigilante in Gotham running around killing people at the same time Wayne Enterprises. Begins to make some aggressive moves toward Stark Industries assets in Gotham. So in attempt to put away Batman and stop Wayne Enteprises. Stark moves his operation to Gotham, gets a mansion on a hill over looking the bay and nearby corperate headquarters. Assume he has more or less the same set up he did back home. His mission is two fold as Iron-Man take out Batman and as Stark stop Wayne. Of course Wayne knows he is gunning for him on both accounts.
For this scenario.
Tony(Iron-Man) will have the his 3 completed suits from the film as well as the Iron-Monger suit all in working order. He has his company/employees(including Potts)/security personel. As well as limited support from the military/SHIELD. Which includes Rhodes as a liason. Just to clarify Stark can loan out his armor if he wants.
Bruce(Batman) will have every suit and gadget he had in all 4 films(Batman, Batman Returns, Batman Forever, and Batman and Robin) as well as every vehicle. Both planes, all three batmobiles, the boats etc. As Bruce he has all his regular buisness assets. As Batman he has help from Robin and BatGirl. They are also fully stocked on vehicles, suits, and gadgets. Of course he also has Alfred. He also has limited Police/Local Government support.
So when these 2 playboy, billionare, superheros go head to head both on the street and in the office. Who comes out on top?
