====Alternate 2014: Thanos' Plan and Nebula's Betrayal====
In an alternate 2014, Thanos discovered that Ronan the Accuser had located the Power Stone. He prepared his daughters, Nebula and Gamora, for a mission to retrieve it. However, Thanos became suspicious of Nebula after detecting that her mind had been tampered with. His concerns grew when he found evidence of her future self's intentions to take the Power Stone for herself.

Thanos ordered Ebony Maw to run diagnostics on Nebula's memory, discovering that her mind had been merged with her future self's memories. Maw revealed that these memories were from nine years later and included information about the Avengers planning to undo Thanos' actions. Realizing that the Avengers were aiming to prevent his future self's actions, Thanos was intrigued by the possibility of his own destiny being altered.

Thanos observed his future self's interactions and the eventual destruction of the Infinity Stones, leading to his own demise at the hands of Thor. This confirmed his belief that his destiny was fulfilled. Understanding that his current actions would shape the future, Thanos decided to use this knowledge to his advantage.

He captured 2023 Nebula and used her to devise a plan involving the Pym Particles, which would allow time travel. Thanos ordered 2014 Nebula to impersonate her future self and recover the Infinity Stones from the future. Thanos also directed Ebony Maw to reverse-engineer the Pym Particles to enable his fleet to time-travel and follow the Avengers.

====Arrival of Thanos in 2023====
After Nebula transported Thanos and his fleet to 2023, Thanos unleashed the Sanctuary II on the Avengers Compound, destroying it and trapping Hulk, War Machine, and [[Rocket Raccoon (Marvel Cinematic Universe)|Rocket Raccoon]] under the debris. Ant-Man eventually rescued them from the rubble.

Thanos then retreated from the wreckage and awaited Nebula's return. He planned to lure the Avengers to him. As Thanos sat amidst the destruction, Thor, Captain America, and Iron Man confronted him. Thanos revealed that his original plan to halve the universe was flawed; the survivors' memories of the deceased would prevent them from flourishing.

Instead, Thanos now intended to use the Infinity Stones to destroy the entire universe and recreate it from scratch. His goal was to create a new universe where its inhabitants would never know about the old one, ensuring that they would be grateful for their existence.

====Battle For The Universe====
Upon hearing Thanos' plans, Captain America told him that the new universe would be born from bloodshed. Thanos countered that the new inhabitants would never know about the past, as he would ensure the Avengers were killed. In response, Thor, Iron Man, and Captain America, filled with disgust and rage, attacked Thanos. Despite their combined might, Thanos easily repelled their assaults.

During the battle, Iron Man and Thor launched an attack against Thanos, but he deflected Iron Man's repulsor blasts with his Double-Edged Sword. Thanos advanced on Iron Man, using him to block a thrown Mjölnir and knocking Iron Man out.

Thanos then retaliated against Captain America, sending him crashing through stones with a powerful punch. He then threw his sword at Thor, who dodged it but lost his weapon when Thanos knocked it away with Stormbreaker. Thanos continued his assault, knocking Thor’s weapon out of his hand and pinning him against a wall before tossing him across the field and pummeling him.

As Thor tried to summon Stormbreaker, Thanos caught it mid-air and attempted to stab him. He began to push the weapon into Thor's chest until Captain America intervened by knocking Thanos away with Mjölnir, proving himself worthy of its power. Thanos then kicked Thor unconscious before turning his attention to Captain America. He endured a series of blows from Mjölnir and Captain America's attacks, with the shield being used effectively to strike him.

Thanos was briefly stunned by a lightning strike from Mjölnir but quickly recovered, slamming Captain America to the ground and removing his damaged helmet. Thanos continued to assault Captain America with his sword, cutting his leg and disarming him. With immense strength, Thanos shattered Captain America's shield and defeated him with a brutal swing of his sword.

While Captain America lay on the ground, Thanos declared that despite his history of conquest and slaughter, his actions had never been personal. However, due to the Avengers' interference, he now intended to destroy Earth out of spite. As Thanos' army of Outriders, Chitauri, Sakaarans, and the Black Order arrived on the battlefield, he saw Captain America rising to confront them.

Unbeknownst to Thanos, Nebula had retrieved the Nano Gauntlet from Hawkeye but was killed by her future self. The Avengers, now joined by all their resurrected allies—including the deceased Avengers, the Guardians of the Galaxy, the Wakandans, the Ravagers, the Masters of the Mystic Arts, and the Einherjar—prepared to fight against Thanos’ forces. Thanos watched tensely as his opponents assembled, and when Captain America gave the command, Thanos raised his Double-Edged Sword to lead his army into battle.

The battle raged fiercely, with neither side gaining the upper hand. Thanos used his sword both as a melee weapon and a boomerang, swiftly dispatching enemies like a Master of the Mystic Arts. Despite several losses on his side, including Cull Obsidian, Thanos fought alongside Corvus Glaive and Ebony Maw. When Thanos inquired about Nebula, he was informed she was not responding and was soon alerted that the Nano Gauntlet was in [[Hawkeye (Marvel Cinematic Universe)|Hawkeye]]’s possession.

Thanos chased after Hawkeye, who passed the Gauntlet to Black Panther. Thanos threw his sword at [[Black Panther (Marvel Cinematic Universe)|Black Panther]], knocking him down but was then confronted by Wanda Maximoff. Maximoff, filled with rage, declared that Thanos had taken everything from her. Thanos, unaware of what his future self had done to Vision, coldly responded that he did not know her and continued to cut through rubble thrown by Maximoff’s telekinetic powers. However, he was soon knocked down by Maximoff's rapid energy blasts and disarmed.

Enduring Wanda Maximoff's relentless attacks, Thanos picked up his Double-Edged Sword and began to counter, deflecting her energy blasts and engaging in close combat. Despite Thanos' superior skill initially giving him the upper hand, Maximoff, driven by anger, managed to repel his attack and slice his sword in half with her telekinesis. Thanos was then lifted by Maximoff's telekinetic grip, causing his armor to be slowly chipped away.

In pain from Maximoff's assault, Thanos ordered Corvus Glaive to initiate an airstrike from the Sanctuary II, despite Glaive’s concern for the lives of their troops. Thanos insisted, leading to a barrage of laser cannons from the warship, which successfully pushed Maximoff and the other Avengers back.

The airstrike was abruptly halted when interference from the sky caused the warship to redirect its fire. Captain Marvel arrived from space and destroyed the Sanctuary II with ease, leaving Thanos in shock. As Captain Marvel began to send the Infinity Stones back into the Quantum Tunnel, Thanos attempted to stop her.

[[Pepper Potts (Marvel Cinematic Universe)|Pepper Potts]], [[Shuri (Marvel Cinematic Universe)|Shuri]], and [[Wasp (Marvel Cinematic Universe)|Wasp]] intervened, allowing Captain Marvel to approach the van. Thanos threw his sword at the Quantum Tunnel in a desperate attempt to destroy it, causing a massive explosion that threw everyone backward. Amid the chaos, Thanos raced to retrieve the Nano Gauntlet, which had been isolated by the blast. Iron Man intervened but was easily thrown aside by Thanos.

Thanos was again thwarted in his attempt to get the Gauntlet as Thor attacked him with brute force. After fending off Thor, Thanos grappled with him and tried to stop him from decapitating him with Stormbreaker. Thor, summoning Mjølnir in addition to Stormbreaker, forced Thanos into a struggle. Despite holding his ground with one hand, Thanos was eventually joined by Captain America, who attempted to push Stormbreaker into Thanos' throat. Thanos managed to knock Thor's weapon down, headbutt Thor, and punch Captain America, knocking both of them out.

As Thanos reached for the Nano Gauntlet, he was attacked by Captain Marvel, who landed two powerful punches. Thanos threw her aside and donned the Gauntlet. As he prepared to snap his fingers, Captain Marvel restrained him, grabbing the Gauntlet. Unable to overpower her, Thanos attempted to headbutt her with little effect and was forced to his knees as Captain Marvel tried to remove the Gauntlet. In a final effort, Thanos pulled out the Power Stone, using its power to punch Captain Marvel out of the battlefield.

====Erasure====
Placing the Power Stone back in the Nano Gauntlet, Thanos prepared to snap his fingers once again. Despite Iron Man's intervention, grappling with him momentarily to prevent the Snap, Thanos managed to knock Iron Man aside and put on the Gauntlet. With an evil smile, he declared himself inevitable and snapped his fingers with the intention of destroying the entire universe and creating a new one.

However, upon snapping his fingers, Thanos was shocked to find that nothing changed. The Infinity Stones had been removed from his Gauntlet and transferred to Iron Man’s Mark 85 armor. Confused and horrified, Thanos watched as Iron Man, now wielding all the Stones, performed the Snap.

Instead of destroying the universe as Thanos had intended, the Snap caused the demise of Thanos’ entire army, including the Black Order, Chitauri, Sakaarans, and Outriders, excluding only Gamora and Nebula. Iron Man sacrificed his own life in the process. Thanos witnessed his adoptive children and alien forces turn to dust before his eyes, and he looked at Captain America with a mix of horror and sadness.

Accepting his fate, Thanos sat on the ground and watched the sunset solemnly, acknowledging that there was no escape this time. As he and his army faded away, Thanos met the same end as his victims had five years earlier, bringing his threat to an end once and for all. However His blood was collected after the battle by [[Nick Fury (Marvel Cinematic Universe)|Nick Fury]]'s secret Skrull unit and placed into a vial known as the Harvest alongside other enhanced DNA samples. The Harvest vial was then administered by Super-Skrulls [[Gravik (Marvel Cinematic Universe)|Gravik]] and [[G'iah (Marvel Cinematic Universe)|G'iah]], granting them access to Thanos' physiology.
