The Avengers have been teaming up in comic books since 1963, so naturally a lot of Marvel's best and brightest have been part of the team at some point. Marvel's Cinematic Universe stayed pretty true to the team's starting line-up with Thor, Iron Man and Incredible Hulk, and with Ant-Man's release this summer, all of the founding members (plus a couple early recruits) are fully represented in the movies, but who's next?
Here is a chronological order of each Avenger as they've entered the team. Marvel published this list in 1996, so there's a full 10 years of recruits not pictured, sorry Wolverine.
