Snap

"I'm a survivor." "Who wants to murder trillions." "With all six Stones, I could simply snap my fingers. They would all cease to exist. I call that mercy."

- Thanos and Doctor Strange

The Snap was the massive fallout across all civilizations and species in the universe, which wiped out fifty percent of all life in random succession after the Infinity Gauntlet was activated. The mass genocide was initiated by Thanos at the end of the Battle of Wakanda, marking the end of his campaign to retrieve all six Infinity Stones.

Thanos' Killing Spree
"This universe is finite, its resources finite. If life is left unchecked, life will cease to exist. It needs correction." "You don't know that!" "I'm the only one who knows that. At least, I'm the only one with the will to act on it."

- Thanos and Gamora In his quest to obtain the Infinity Stones, Thanos invaded Nidavellir and forced the Dwarves to create the Infinity Gauntlet, a golden glove capable of harnessing the power of the Infinity Stones. Thanos later massacred every single one of them, save for Eitri. After Thanos invaded Xandar, destroyed the Nova Corps, and stole the Power Stone from the Orb, he slaughtered half of the Xandarians as part of his desire to balance the universe. After having retrieved the Power Stone, Thanos and the Black Order intercepted the Statesman, which was carrying the Asgardian survivors of the cataclysm, Ragnarök. While the Black Order slaughtered half of the ship's population, Thanos personally confronted and defeated Thor, the new king of the Asgardians with Asgard having been destroyed. After easily defeating Hulk in single combat, he murdered Heimdall after he used his last breath to send Hulk back to Earth by way of the Bifrost. He then forced Loki to give up the Tesseract by threatening to kill Thor. After Loki gave it to him and then tried to kill him, he murdered Loki as well. Thanos crushed the Tesseract in his hand, revealing the Space Stone as its power source. Having gained the next stone, he destroyed the Statesman with the Power Stone, leaving Thor and the dead Asgardians in space. On Earth, Hulk, who was saved by Heimdall's Bifrost Bridge, crashed into the New York Sanctum and warned the Masters of the Mystic Arts of Thanos' incoming arrival. Doctor Strange, Wong, Iron Man and Hulk gathered at the Sanctum and discussed the history of the Infinity Stones' history across the Nine Realms. However, Ebony Maw and Cull Obsidian launched an assault in New York City, prompting the four to fight back. During the ensuing battle, however, Doctor Strange was abducted by Ebony Maw, while Wong sent Cull Obsidian through a portal to the Arctic. Iron Man and Spider-Man, who left his school bus to help them, managed to sneak onto the Q-Ship. Eventually, Iron Man and Spider-Man rescued Doctor Strange and created a hole in the ship which sucked Maw into deep space, killing him. The three then decided to confront Thanos on his home planet, Titan. In Edinburgh, Vision and Scarlet Witch were ambushed by Proxima Midnight and Corvus Glaive, who attempted to draw the Mind Stone out of Vision's head. The couple then received combined reinforcements from Captain America, Black Widow and Falcon. Thanos' two children retreated and the five Avengers traveled to the New Avengers Facility to discuss the Mind Stone.

Obtaining the Reality Stone
Meanwhile, Thanos personally traveled to Knowhere to obtain the Reality Stone, which was entrusted to the Collector after the conclusion of the Second Dark Elf Conflict. He infiltrated the Collector's museum and located the Reality Stone, which was in the form of the Aether. He then solidified the Aether into the Reality Stone and added it to his Infinity Gauntlet. As Peter Quill, Gamora, Drax the Destroyer, and Mantis arrived on Knowhere to confront Thanos, he conjured a false illusion of him interrogating and torturing the Collector into revealing the location of the Stone, having accurately predicted that the Guardians of the Galaxy would pursue him to Knowhere.

Obtaining the Soul Stone
The illusion worked perfectly and Thanos abducted Gamora and forced her to divulge the location of the Soul Stone with the threat of torturing her sister Nebula with the Power and Space Stones. Thanos' threat forced her to reveal the stone's location, which was hidden on Vormir. Thanos and Gamora then traveled to the mysterious planet, where they were greeted by the Red Skull, who became the stone's guardian as a punishment for abusing the Tesseract's power during World War II. After hearing Red Skull's elucidation that he would have to sacrifice someone he loved in order to obtain the Infinity Stone, he tearfully threw Gamora from the cliff and was granted possession the Soul Stone.

The Last Confrontations


"We're in the endgame now."

- Doctor Strange

On Earth, the Avengers traveled to Wakanda and tasked Shuri with removing Vision's stone so it could be destroyed without killing him. However, Wakanda soon was attacked by the Black Order and Thanos' army of Outriders, who demanded the Mind Stone. Led into battle by Captain America, Bucky Barnes, Black Panther, the Dora Milaje, Jabari Tribe, Border Tribe, and the Wakandan Royal Guard fought back. Thor arrived on Wakanda with his newly forged weapon Stormbreaker, along with Rocket Raccoon and Groot. The Outriders and the remaining members of the Black Order were eventually defeated and killed. Meanwhile, on Titan, Thanos was confronted by the combined efforts of Doctor Strange, Iron Man, Spider-Man, Star-Lord, Drax the Destroyer, Mantis and Nebula. Although the seven managed to briefly overwhelm Thanos, he used the power of the four stones to gain the upper hand. A beaten Doctor Strange then relinquished the Time Stone to Thanos so that he wouldn't kill Stark. Having obtained the fifth stone, Thanos used the Space stone to teleport himself to Wakanda. In the forests of Wakanda, Thanos appeared and used the stones to subdue the Avengers before making his way to Scarlet Witch, who was using her powers to destroy the Mind Stone in Vision's forehead. Although she managed to destroy the last stone and Vision with it, Thanos used the Time Stone to reverse Wanda's act and restore Vision to his former state so he could pull the Mind Stone from Vision's head. However, Thanos was suddenly attacked by Thor, who impaled him in the chest with Stormbreaker.

As Thor denigrated Thanos because of his actions during the Attack on the Statesman and warned him that he would die for murdering Loki, Heimdall, and half of the Asgardians, Thanos simply replied and taunted him that he should have aimed for his head. Thanos snapped his fingers, sending out a blinding light and causing Thanos to pass out.

He awakened in the Soulworld where he approached a younger Gamora, who asked him if he completed his mission, to which he solemnly replied yes. Gamora asked what it cost him, to which he replied "Everything". Thanos then returned to his consciousness and used the Space Stone to transport himself to the Garden where he intended to peacefully spend his retirement after he fulfilled his goal.

The Snap
"World governments are in pieces. The parts that are still working are trying to take a census. And it looks like he did... he did exactly what he said he was gonna do. Thanos wiped out fifty percent of all living creatures."

- Natasha Romanoff

The destructive toll of the Snap quickly became apparent, as half of all life in the universe disintegrated into ashes. Outside Earth and Titan were several Asgardian casualties, such as Sif and an Asgardian actor who portrayed Loki in The Tragedy of Loki of Asgard. Even dimensions across the Multiverse, such as the Quantum Realm, were affected by the Snap.

Earth
On Earth, there were at least 3,200,000,000 humans confirmed deceased or missing worldwide, according to a statistic in the New Avengers Facility. Not only sentient beings were perished in the Snap, but all life forms, from animals to bacteria in the survivors' digestive systems, died off as well. In Wakanda, Bucky Barnes was one of the first to die, crumbling into dust in front of Steve Rogers and Thor. The raging battle quickly wound down into a ceasefire as many Wakandan soldiers and Dora Milaje operatives corroded into dust, while M'Baku and other survivors watched in horror. Casualties of the Golden Tribe included Shuri and T'Challa, who collapsed into dust in front of Okoye. Rocket Raccoon tearfully watched Groot vanishing into dust, as he could do nothing to save his life. Kneeling over Vision's lifeless body, Maximoff peacefully vanished into dust. Hidden in long grass, Falcon disintegrated as James Rhodes called out to him, not realizing his companion was already gone. The United States of America had broadcasted a in the wake of the erasing of many of the country's citizens. In Atlanta, Nick Fury and Maria Hill while driving witnessed the Snap claiming the lives of the civilians around them, plunging the city into chaos. As Hill disintegrated before Fury's eyes, the former Director hurried to retrieve his last resort Transmitter Pager. Realizing he was disintegrating as well, Fury managed to use to transmit a last-ditch distress call to distant Captain Marvel before he was reduced to dust. In San Francisco, Hank Pym, Janet van Dyne, and Hope van Dyne planned to send Ant-Man in the Quantum Realm to extract quantum energy to aid Ava Starr. Using the portable Quantum Tunnel in Luis' Van, Lang made his way to the Quantum Realm and harvested needed energy. However, Pym, Hope, and Janet were all erased from existence, leaving Lang stranded in the Quantum Realm. The van was later impounded and put into a unit for storage along with the remainder of Lang's possessions. At Midtown School of Science and Technology in New York City, the high school was gathered in the gymnasium watching the marching band at the time of the snap. Half the band and audience disintegrated, much to the shock of the survivors. Among those who were killed were Ned Leeds, Michelle Jones, Flash Thompson, Betty Brant, Jason Ionello, Sue Lorman, and Andre Wilson. Among the billions of other victims of the Snap on Earth were Laura Barton and her three children, Cooper, Lila, and Nathaniel, who perished at their homestead, May Parker, who was killed in her home, Betty Ross, a former S.H.I.E.L.D. agent, Erik Selvig, Sharon Carter , Isaiah Sorenson, Cammie Conroy, David Jerome, Elijah Cortez, Karen Oggerton, and Billy Peskers.

Titan
On Titan, in the aftermath of their defeat by Thanos, the effects of the gauntlet began to claim some more lives. Mantis was alerted to what was happening and soon became the first to vanish followed by Drax and then Star-Lord. Doctor Strange claimed there was no other way to win and soon vanished. Lastly, Spider-Man, also being alerted by his Spider-Sense, succumbed to the effects of the Snap while desperately begging to live before giving in and dying in Iron Man's arms, leaving him and Nebula as the only survivors on Titan.

As the effects of Thanos' mass genocide took hold across the universe, the remaining survivors could do nothing but accept the reality of Thanos' overpowering ascendancy and the consequences it had for them and the rest of the universe.

Universal Repercussions
On Earth, the majority of world governments were in a state of total anarchy due to not being able to take a census of the situation out of the countries that weren't in a state of instability, although it became quite clear that half of all living creatures had been exterminated. Over the course of five years, the victims of the Snap would come to be known as the Vanished, with memorial sites erected in the honor of those that died in every city in the world.

A quarter of all children worldwide were left orphaned in the wake of the Snap; an organization in Washington, D.C. was placed in charge of such orphans.

Post-Battle of Wakanda
"The universe required correction. After that, the stones served no purpose beyond temptation." "You murdered trillions!"

- Thanos and Bruce Banner In the aftermath of the Battle of Wakanda in 2018, Captain Marvel arrived on Earth upon being hailed by Nick Fury with the Transmitter Pager. Finding herself with the remaining Avengers at the New Avengers Facility, she inquired about Fury's death, and later traversed to find Tony Stark, who was adrift in space on the Benatar, previously stranded on Titan. Danvers was able to locate the Benatar and brought Stark and Nebula to the New Avengers Facility. After Stark's recovery, Danvers and the Avengers traveled to Planet 0259-S, where they recognized a power signature emitting from the planet's surface, similar to the power signature the activated Infinity Gauntlet emitted. Arriving on Planet 0259-S, they learned from Thanos that he used the Infinity Stones to destroy each other. With all hope lost, Thor beheaded Thanos with Stormbreaker.

Time Heist
In 2023, after spending five hours trapped inside the Quantum Realm, Scott Lang managed to escape and witness the aftermath of the Snap for the first time, having not seen it happen. Upon emerging five years, Lang deduced what happened and panicked, fearing that his daughter Cassie was among the Snap's victims. Lang found his own name on a memorial dedicated to the Snap victims, but not his daughter's, so he ran to his house to be reunited with his family, including an older Cassie.

Lang then traveled to the New Avengers Facility, where he proposed the idea to reverse the Snap by traveling back in time to obtain alternate versions of the Infinity Stones from the past.

Using the Quantum Theory, the Avengers then started building a time machine. Once completing the device and running several tests with it, they used it to go to various alternate versions of pivotal moments in the past to fetch the Infinity Stones. Scott Lang, Tony Stark, Bruce Banner, and Steve Rogers traveled to the Battle of New York in 2012 to retrieve the Space, Mind, and Time Stones, although the Space Stone later had to be obtained from Camp Lehigh in 1970 after a series of events resulted in 2012 Loki escaping with the Tesseract. Meanwhile, Thor and Rocket Raccoon traveled to Asgard in 2013 to extract the Reality Stone from Jane Foster, as Nebula, Natasha Romanoff, Clint Barton, and James Rhodes traveled to Morag and Vormir in 2014 for the Power and Soul Stones respectively. When the Avengers had finally acquired all the Infinity Stones from the past, they returned to 2023, unaware that a version of Nebula from the alternate 2014 had joined them to bring Thanos to their time period. As they fit the Stones into a Stark-created Nano Gauntlet, it was decided that Banner would be the one to wield it. Despite great difficulty and the pain of wielding the Infinity Stones' raw power, Banner was able to snap his fingers and ultimately undo the Snap. The Avengers were alerted to Banner's success when Ant-Man witnessed several birds outdoors seemingly appear out of nowhere, while Hawkeye received an incoming call from his wife, an initial victim of the Snap.

Mark in History
The Snap was remembered as a historical event. Although the Blip eventually brought back all living beings who perished by Thanos' actions, their sudden return surprised most of the survivors, who had moved on with their lives without thinking they would ever return. It also caused confusion within the identity documents about the age of the Snap's victims as those who returned in the Blip remained the same age as they were in 2018 before the Snap despite the five years since then. The students of Midtown who were killed in the snap had to start their whole school year over the following term despite the fact that they already completed midterms much to their frustration. The year following the Time Heist, a documentary film about the event, entitled The Snap, was released.

Trivia

 * In the non-canon book The Cosmic Quest Volume Two: Aftermath, the Snap is referred as The Decimation.
 * The Thanos page on google added a cartoonish-like Infinity Gauntlet on the bottom left-hand corner. When it is clicked, half of the search results will disintegrate. When it is clicked again, the Time Stone reverses the damage and brings back the disintegrated search results.

Behind the Scenes

 * Kevin Feige has said that half of "all life" in the universe was erased from existence, including all sentient and insentient beings.
 * The term "Blip" originated in Spider-Man: Far From Home, used to describe both half of the population disappearing due to Thanos' Snap as well as their resurrection five years later. However, following the movie's release, Kevin Feige clarified that despite Marvel Studios internally referring to both events as the Blip, the MCU fans adoption of the term "Snap" would now be used to denote Thanos' use of the six Infinity Stones, while "Blip" would henceforth be referred to as Bruce Banner's reversal of the Snap.
