Spoiler warning: spoilers for Avengers: Endgame ahead.
Avengers: Endgame directors Joe and Anthony Russo have gone on record saying they don’t know if the 2014 version of Gamora survived Endgame or not.
In an interview with Business Insider, the Russos were asked what happened to Gamora at the end of Endgame, as Star-Lord is seen during the end of the film using a computer screen to search for her. Joe replied “We don’t know whether she was dusted or whether she survived. That’s probably a question that Guardians
will answer.”
