by Diamond Select Ultimate Bust Collection The one constant in the universe is change. Change is at the heart of the Ultimate Marvel Universe from Marvel Comics, and no stone has been left unturned. In order to create a brand new Marvel Universe, plenty of things were re-arranged though much of the overall setting is the same. New York is still New York (aka superhero central), Bruce Banner is still the Hulk, Steve Rogers is still Captain America, and Tony Stark is still Iron Man.
Being Iron Man requires a few things, and as luck would have it, Tony Stark has them all. To build and maintain the suits of armor you would need access to high technology and money. Being a billionaire (worth roughly $350 billion) helps, especially when you head up one of the world's leading technology companies. You would need a brilliant mind, and be able to choose the right people to work with you, and Tony has those qualities as well.
