I am a new billionaire in town, known for having the biggest weapons hustle. Stark does technology and I do weapons. When I move to New York into my own tower the team gets curious. Tony approaches me to learn if I’m good or bad news and figures out that he really likes me. I meet the avengers and they approve but I don’t want to join them. Eventually though Stark and I fall in love. His genius matches mine and we banter pretty easily. But am I doing something nefarious on the side? The team will have to find out.
