The Hulk’s snap refers to the moment in Avengers: Endgame when Bruce Banner, aka the Hulk, uses the Infinity Stones to reverse the effects of Thanos’ snap from Avengers: Infinity War. The snap in Infinity War had wiped out half of all life in the universe, and the Hulk’s snap was a desperate attempt to bring everyone back. However, the consequences of the Hulk’s snap were far-reaching and complex, and they had a significant impact on the Marvel Cinematic Universe. Here are some of the things that the Hulk’s snap did:

- Bring Back the Disappeared: The most immediate and significant effect of the Hulk’s snap was that it brought back all the people who had disappeared in the previous snap. This included a vast array of characters, from major heroes like Spider-Man and Black Panther to ordinary people who had been caught up in the chaos. This reversal of the snap was a significant turning point in the film and a moment of great relief for the surviving heroes.
- Damage to the Hulk: The Hulk’s snap had a physical impact on Bruce Banner, as it required him to use his own body as a conduit for the power of the Infinity Stones. This caused him to suffer significant injuries, and he was left with a damaged arm that he was unable to use effectively. This damage was a reminder of the risks involved in using the Infinity Stones and foreshadowed the events of later films.
- Creation of Alternate Timelines: One of the more complex consequences of the Hulk’s snap was the creation of alternate timelines. This happened because the snap reversed the events of the previous snap, effectively altering the course of history. As a result, alternate timelines were created in which different events occurred, and different versions of characters existed. This set the stage for the events of later films like Loki and What If…?.
- Release of Thanos’ Army: The Hulk’s snap also had an unintended consequence, which was the release of Thanos’ army. When the snap was performed, it sent out a burst of energy that was detected by Thanos and his forces. This prompted them to travel to the main timeline to try and reclaim the Infinity Stones and complete their mission. This led to a massive battle in Avengers: Endgame, which saw the heroes fighting for the fate of the universe.
- Death of Tony Stark: Perhaps the most significant consequence of the Hulk’s snap was the death of Tony Stark, aka Iron Man. In the final battle against Thanos and his army, Stark used the Infinity Stones to snap them out of existence. This was a moment of great sacrifice, as it required him to use his own life force to wield the power of the Stones. The death of Iron Man was a significant turning point for the Marvel Cinematic Universe and had a profound impact on the remaining heroes.
In conclusion, the Hulk’s snap in Avengers: Endgame had a significant impact on the Marvel Cinematic Universe. It brought back all the people who had disappeared in the previous snap, damaged the Hulk physically, created alternate timelines, released Thanos’ army, and ultimately led to the death of Tony Stark. While the snap was a moment of great relief for the heroes, it also had unintended consequences that set the stage for the events of later films.
