8 Major Theories For Guardians Of The Galaxy Vol 3
6. It Will Revolve Around The Search For Gamora
Though half the entire universe disintegrated in the wake of Thanos' snap, there were three big players that bit the dust before the stones were assembled. As Rocket would put it, these were really gone rather than just kinda gone. Loki, Vision, and the Guardians' own Gamora.
After being thrown from the cliffs of Vormir, Thanos' favourite daughter fell to her death to the dismay of Peter Quill, Nebula, and the rest of the team. In Endgame however, Gamora returned to the fray in a way. While it was certainly Gamora that re-united with Quill and fought her father in the final battle, it was 2014 Gamora, from before she met Star Lord, joined the team, or changed her villainous ways.
A deleted scene from Endgame showed Gamora alive and well after Iron Man snapped his fingers, so we know she is still around in this new timeline, and with Quill searching for her on his dashboard before being interrupted by Thor, signs point to a search operation.
Since first coming together in the Kyln, Quill, Gamora, Drax, Rocket, and Groot have become more than a team, and with the later additions of Nebula and Mantis, they have become a family. If they know that Gamora is out there somewhere, there is no way they leave her be.
