Warning: Contains SPOILERS for Ultraman X Avengers #2! The Avengers started off as an exclusive team of heroes, but it quickly became much more of a revolving door for any superhero to claim an Avengers title whenever the world needed saving. While, overall, thats a good thing, and allows for a variety of heroes to become Avengers (if even just for a storyline or two), it apparently ruined the integrity of the team, especially after one hero in particular joined its ranks.
