Re: Avengers 2: Age of Ultron
BP was not an original team member. He came along later. Iron Man, Thor, Wasp, Ant-Man/Giant-Man, Hulk and maybe Captain America(he's really the first recruit) can be seen as the original team. That's about it.
Currently enduring a general malaise at the quality of live action Marvel/DC shows on network TV. Hopefully NetFlix can remedy that.
