-Thanos is now at peace on his Shrine he created in honour of her beloved step daughter Gamora, although years have passed he still mourned for her.
-Thanos constantly visits Vormir to commemorate Gamora's death.
-Thanos still possessed with the heavily damaged Infinity Gauntlet.The gauntlet is beyond repair and incapable of controlling the gems together but he can still use the stones one at a time.
-Hank Pym determined to get her daughter back as well as saving others who were victims of the Thanos Snap... proposes that if they harnessed the power of the Quantum Realm there's a possibility, that they will be able to open a portal to a parallel reality where Thanos hasnt yet gathered the stones.. In that way, they get the upperhand of getting the Infinity stones before Thanos does.
-as explained by Hank, Quantum Realm is a place where the concepts of time and space are irrelevant, hence molecular displacement in particular time periods to a parallel universe are possible..
-in Japan, BlackWidow tracks down Hawkeye who now identifies himself as Ronin.Natasha told him that Avengers needs him. Clint refuses to join, saying that all is lost referring to his family that vanished in the Snap, blaming the Avengers.

-Hank Pym explains that in order for this Plan to work, each of the Avengers were given with Pym tech Quantum regulators they wear in their hands, so that in that way they retain their memories during their travel in the fabric of irregular space-time of Quantum Realm.
-Cap goes first in the Quantum Realm, and was spefically displaced back in time of World War 2, to ensure that Peggy and SSR(later SHIELD) gets a hold of Tesseract(Space Stone) from Hydra. Cap made the last dance with Peggy before going after the Hydra base of the Red Skull. Cap goes to battle Red Skull but escapes, and crashes again in the Arctic. (this ensures that Cap will be discovered by SHIELD in the Arctic and have the Tesseract)
-Tony, Thor, BlackWidow, Ronin, Hulk, Antman, War Machine, Vision and Cap(who awakened from his icy slumber in the Arctic by SHIELD with his memory of the Main Universe) goes in the Quantum Realm to battle Loki in NY again.
-at one point, Cap weilds the Mjolnir to defeat Loki
Loki was taken by SHIELD, Nick Fury interrogates him using The Scepter(Mind Stone), revealing Thanos being responsible for the Attack. Thor's agrees to imprison Loki in Midgard instead of being held in Asgard.
while the Avengers deal with Loki..Thor travels back to Asgard to retrieve The Aether(Reality Stone) from the Vaults of Asgard. Odin seems to have the understanding behind Thor's actions and let his son have the Aether.( this averts the events of Thor: Dark World, the dark elf Malekith still in its deep sleep)
-Rocket and Nebula goes in the Quantum Realm to get the Orb(Power Stone) in Morag before Peter Quill retrieves it.(this caused for Peter Quill to be captured by Korath emptyhanded, the events in GOTG never happened but Quill managed to escape from the Kree by the help of Yondu)
-Meanwhile, the Avengers created a diversion to get the Tesseract(Space Stone) and Scepter(Mind Stone) of Loki knowing that SHIELD was infiltrated by Hydra already. They successfully got the stones. (this averts the creation of Ultron and the events of Age of Ultron to have never happened in this universe)
-Tony and Cap goes to Sanctum Sanctorum, meets Dr.Strange which already a Sorcerer Supreme by this time in this universe. Tony explains that they need the Time Stone. Dr. Strange told them that he is expecting to see both of them
-Somehow, Dr. Strange of the Parallel Universe communicates with Dr. Strange of the Main Universe peering thru the Eye of Agamotto(Time Stone) who was currently in Titan(as if the events of Avengers: Infinity War was about still to take place), checking 14,000,605 alternate timelines.(and this very moment, Dr. Strange of both realities sees that this is the ONLY way they can defeat Thanos, by making the Thanos Snap happen in order to have Dr. Strange INSIDE the Soul Stone). Dr.Strange realizes they have no way of getting that gauntlet off from Thanos hands but they have to destroy it from the inside.
-As they were speaking, the battle with Thanos in Titan takes place in the main timeline, events that happened in Infinity War.
-Dr Strange of the Parallel Universe awakens Dr. Strange of Main Universe inside the Soul Stone plane of existence. Dr. Strange of the Parallel Universe then provides Tony the Time Stone and a Sling Ring.
-Dr. Strange of the Parallel Universe also reveals to Tony that all those perished in the Thanos Snap are inside the Soul Stone in astral bodies trapped in an astral plane called Soul World.
-Here, also revealed that Dr.Strange puts a hex to the Time Stone and the Infinity Gauntlet so that by the time Thanos does the Snap, which Dr. Strange knew because Thanos himself told Dr.Strange what he will do once he gathers all the stones; if used together, the Gauntlet will break.
Avengers came back to Wakanda bringing Space, Mind and Time Stones respectively, Thor bringing the Reality Stone and Rocket with Nebula brought the Power Stone. 5 stones in all.
Shuri completes the creation of the second gauntlet and struggles in placing the gathered 5 Infinity Stones except for the Soul Stone.
-Tony deduces that there's no way they'll sacrifice one of themselves in Vormir in return of getting the Soul Stone in the alternate reality although Captain America is willing to put forward his self as sacrifice. This caused a heated argument among the Avengers.
-Nebula instead put forward a plan to lure Thanos to Vormir for the Avengers to get the Soul Stone. Which they are doubtful if will work. Nebula who has a change of heart, tries to redeem herself with this act of sacrifice.
-meanwhile, Thanos learns that the Infinity Gauntlet in no time cant hold the Infinity Stones any longer due to the inflicted damage caused by the Snap and the stones arent working together properly to what he wishes..the stones powers were dampened Except for the Soul Stone. Thanos sensed that the Avengers must have been the reason behind it. Thanos orders for an attack, sending his fleet to Earth.
-Thor and Rocket proposes IF they will attack Thanos in his Shrine, the Earth would be render defenseless from Thanos armada. so Thor put forward a plan to gather a massive army, an alliance of sort, enough to repel Thanos forces that is coming to Earth. All agreed.
-Thor and Rocket travels the distant galaxies to summon an army using the Bifrost ability of the Stormbreaker, meets all Ravagers under Stakar's(StarHawk) leadership. The Ravagers joins them against Thanos.
-Captain Marvel receiving the Code Red distress signal coming from Nick Fury, alerts her.
-Carol Danvers were patrolling the Negative Zone, which she was tasked of guarding so that Skrulls-Kree war criminals will not be able to escape the dimension, which she use as their prison. Because of time dilation effects, Carol hasnt aged that much since the time she stayed in the Negative Zone.

-Avengers on Wakanda plans to enter the Soul World in order to contact Dr.Strange that is inside of it. AntMan proposes an idea to join Nebula on its way to the Shrine, to attempt on using his shrinking regulator to pass thru sub-atomic to enter the Soul Stone.
-as Thanos were about to go to Earth, he was put in a halt because of Nebula's arrival in the Shrine. Nebula tries to deceive Thanos telling him that she is giving her loyalty back and tries to convince him that there's a way to revive Gamora without undoing the Thanos Snap.(it was revealed that Thanos were trying to revive Gamora in the past but unsuccessful because the Soul Stone requires a sacrifice upon ressurecting someone -- "a soul for a soul").
-Nebula offers herself to Thanos as a willing sacrifice to Vormir in order to revive Gamora.Thanos dont believe her.
-Thanos uses the Mind Stone to read Nebula's mind, revealing the Avengers plan, and learns that its a trap. AntMan right away, uses his regulator to shrink sub-atomic to enter the Soul Stone. Thanos notices it.
-enraged Thanos, follows AntMan to the Soul World. Nebula's plan work, as Thanos astral body enters the Soul World he leaves behind his physical body vulnerable. Avengers(Ironman, Cap, Black Widow, and Vision) then sprint to action, hiding from the distance to get the Infinity Gauntlet off from the weakened, immobilized Thanos.
-meanwhile, Dr.Strange of the main universe awakens from dormant state inside the Soul World. He was contacted by his self from an alternate universe assisting Tony and Cap ensure they will win against Thanos. Dr.Strange then used his magic to locate other heroes like Spiderman, Mantis, etc in the Soul World. Mantis awakes all of these heroes.
-inside the Soul World, an astral plane inside the Soul Stone where trillions of trillions of souls trapped in hibernation. AntMan and Dr.Strange along with the rest of the vanished heroes meet. Antman gave Dr.Strange a Sling Ring provided by Tony. Thanos finds them and battles ensues. While this was taking place, the rest of the Avengers were battling the weakened physical Thanos in order to get the gauntlet.
-back on Earth, Thanos forces were about to enter the atmosphere but intercepted by the Ravagers, Thor, Rocket and Captain Marvel. in Wakanda, Bruce and Shuri were still working with the stones, placing them one at a time in the Stark gauntlet. Ronin and WarMachine watches from afar, ready to defend the Stark gauntlet at all cost from Thanos forces attacking Earth.
-Thanos inside the Soul World overpowers Dr.Strange, AntMan, The Wasp, Spiderman, BlackPanther, WinterSoldier, Scarlet Witch, Falcon, StarLord, Drax, Groot and Mantis. then Thanos realized it. He left his physical body vulnerable to attack and realized that this was all a diversion to get the gauntlet. Thanos hastily went back to his physical body.
-Avengers were unsuccessful to get the Gauntlet from Thanos. When the Mad Titan was about to use the damaged gauntlet, Dr.Strange unleashed the hex he casted in the Time Stone in their previous battle back in Titan. The hex caused disharmony among the stones. the Power Stone can no longer be hold into place, it exploded!!! Disrupting the Time stone, Reality Stone and Mind Stone while it caused the Soul Stone to broke off from the gauntlet.
