20 Insane MCU Moments Marvel Didn't Show
12. The Dormammu Vision (Avengers: Endgame)
During the time-heist in Avengers: Endgame, Hulk is tasked with obtaining the Time Stone from The Ancient One. The Ancient One is reluctant to give up the artefact but does so when she learns Doctor Strange offered the Time Stone to Thanos willingly, believing it was the only way to defeat him.
Originally, The Ancient One explained that she couldn't give the Time Stone to Hulk due to a time paradox. If Hulk failed in his mission, he would not be able to return the Stone to The Ancient One.
If she didn't have the Stone, then Strange couldn't use it to defeat Dormammu, as was shown in the conclusion of Doctor Strange. To help Hulk understand the consequences of his failure, The Ancient One would show him a vision of the future where Dormammu has laid waste to Earth and taken over the entire dimension.
This scene would have been cool but it was unnecessary and so, was cut.
