9 Theories That Answer HUGE MCU Mysteries
4. Gamora Was Killed By Tony Stark
When Tony Stark stole the infinity stones back from Thanos and snapped his fingers, he disintegrated The Mad Titan and his entire army. For the most part, the distinction between the good guys and bad guys was perfectly clear. However, the status of Gamora was certainly more of a grey area.
Thanos' daughter had turned against her father to help Nebula and the Avengers, but would Tony have known that? We don't see Gamora vanish, nor do we see her stand with Nebula and the Guardians at Tony's funeral. There was a deleted scene that showed her walk away from the battle unharmed, but since this didn't make the final cut of the movie we can't guarantee its credibility. So what happened to Gamora? Where is she now?
The way Star Lord was looking up his love as Thor entered his ship at the end of Endgame, seemed to suggest he would be searching for her in the near future, but maybe, she simply died with the rest of Thanos' forces.
The actual physics of the snap remain a mystery at this point, but Tony Stark must have communicated to the stones somehow who to get rid of. Since it is literally just a snap of the fingers, with no time to pinpoint any individuals, Tony, according to this theory, would have simply dusted everyone who came to the future from 2014. This would, of course, include Gamora.
