The Story of Tony Stark/Iron Man (Marvel Cinematic Universe)

Time Heist: Battle of Earth

With the rest of the Avengers in place with all of they're allies and other worlds had gathered around to battle Thanos' army, Iron Man dropped down to line up against with them as all began to prepare for battle. He landed closely with his teammates and noticed Captain America holding Mjølnir, assembling the team to fight for their planet.

The entire team and other forces began to charge with fury attentions, running towards Thanos forces as he sends his Black Order, Chitauri army, Sakaaran army, and the Outriders to kill them all. Iron Man flew across the battlefield with his allies and began to use his unibeam to attack any nearby threats. Iron Man then teamed up with Pepper Potts, who was donning her own Iron Armor, and fought alongside each other in aerial combat.

While attacking the many Outriders that are trying to kill him from above, Iron Man landed on the ground and blasted many incoming Outriders with his laser beams. While successfully winning his fight, Iron Man was then attacked by Cull Obsidian, landing onto a piece of rubble after getting knocked down. Iron Man tried to kill Obsidian with his repulsors but was proven to be ineffective. Iron Man was then saved by Spider-Man who pulled Obsidian down onto the ground with usage of his Web-Shooters, allowing Giant-Man to crush Obsidian to death.

Stark removed his own helmet to catch his breath after being almost killed only for Peter Parker to give him hand while he was on the ground. Parker told Stark about himself being in space and was turned into dust moments when he passed out. Peter further noted that Strange was there with him on Titan and began to wake him up to tell the rest that they need him. Stark happily grew closer to Parker after listening to him again, hugging him afterwards during the battle that was going on.

Stark flew over to Doctor Strange, who was bringing down a group of Thanos' forces into another dimension during the battlefield, and asked him whether this was the one the fourteen million futures that they'll win. Strange told him that if Stark knew what needed to happen, it wouldn't happen. Much to his skepticism, Stark decided to keep being optimistic and told Strange that he hoped that he was right about the outcome. Shortly after Thanos rain fire on the battlefield, Captain Marvel destroyed the Sanctuary II, much to Stark's surprise.

Upon Captain Marvel retrieving the Nano Gauntlet from Spider-Man, she lost the item in an explosion which landed on the ground. After discovering the Nano Gauntlet in front of him, Stark prevented Thanos from getting the Gauntlet by tackling him, only to be knocked down and stalemated once again. While Stark rested for awhile he was knocked out, Thor, Captain America, and Captain Marvel tried to kill Thanos only to fail due to his fighting prowess.

After recovering from his knock out, Stark turned to Strange, who, visibly shocked, signaled to him that this was the one timeline he foresaw where they won. Finally realizing why Strange sacrificed the Time Stone five years ago to save his life and what had to be done, Tony briefly grabbed Thanos's arm, clinging onto the Nano Gauntlet, but was knocked to one side. Thanos triumphantly declared himself inevitable, before snapping his fingers once more.
