(This is Tragic)
There have been many different teams of Avengers in Marvel's history, but the West Coast Avengers are without a doubt the one with the most tragic history.
During their long tenure, this spin-off of the original Avengers experienced a sequence of adversities and tragedies that affected each of its members.
The Avengers of the West Coast were created in the aftermath of the first Secret Wars by Vision, who at the time was the Avengers' chairman.
The synthezoid believed that one team of Avengers was not enough to face threats to Earth's safety, so he tasked Hawkeye with selecting a team and setting up headquarters near Los Angeles.
The original lineup included Hawkeye's wife Bobbi Morse, aka Mockingbird, Wonder Man, Tigra, and Iron Man. The team, however, seemed doomed since its inception.
Overall, the Avengers of the West Coast had a long and entertaining run. The team was considered more irreverent than the East Coast one, and it focused on unconventional, "damaged" heroes.
The members experienced many personal tragedies that ended up having a negative impact on the team but the West Coast Avengers are still remembered and beloved by fans, to the point that there are rumors of them being introduced to the MCU soon.
