Guardians Of The Galaxy Vol. 2 - 10 Biggest Things We Still Don't Know
4. Does Nebula Become A Guardian?
The Question: It's already been confirmed that Yondu and Mantis will be joining the core Guardians line-up, but with Nebula teaming with the gang on their next mission, will she also become a fully-fledged member, or is she merely riding shotgun for a while?
The Likely Answer: Given that she's clearly a prisoner for much of the movie and has at least one epic fight with Gamora, it doesn't seem likely. She'll most probably end up a casual acquaintance of the team, an uneasy ally who is useful due to her shared hated of Thanos.
As Nebula will reportedly appear in Avengers: Infinity War too, don't be surprised if she's a major key to bringing Thanos down, being his adopted daughter and all. That link is what will keep her in the good graces of both the Guardians and the Avengers.
