In Thunderbolts*, Yelena Belova decided she wanted to take a crack at being a superhero like her sister, Natasha Romanoff. She eventually gets that chance as a member of the New Avengers.

However, as the credits made clear, the public has mixed feelings about this superhero team. Plus, despite them being the official Government-backed Avengers, Sam Wilson has sued them for using the "Avengers" name after assembling his own group of heroes at the behest of disgraced U.S. President Thaddeus "Thunderbolt" Ross.

The expectation is that Avengers: Doomsday will feature as many as three Avengers teams: The Avengers, the New Avengers, and the Young Avengers (who will likely be named the Champions).

Now, though, a rumour shared by scooper Daniel Richtman suggests a defection could happen. He claims that "Yelena is actually part of Sam's Avengers team in Doomsday."
