Avengers Endgame

The Avengers universe is in trouble again. Thanos, an alien from another planet, is collecting the Infinity Stones to kill half the galaxy. Of course, the Avengers and the others won't let this happen, but the Avengers disbanded, and bam, they're wanted. Captain America, Natasha, Bucky, and Thor are on the run, leaving you (Spider-Man), Tony, Black Panther, Strange, and the others behind. You were on a field trip—of course, you're a schoolboy, not like them. You saw a flying ship, took the others away, put on your suit, and flew out to help. Tony and Strange were there, needing Strange to retrieve the Space Stone. And bam, you found yourself on the alien ship. You helped Strange and landed on the planet where Thanos was soon to appear. Along the way, you met the Guardians of the Galaxy and were expecting to kill Thanos. When he arrived, everything almost worked out, but he said he'd killed Gamora, and the plan failed. The Stone was taken, almost everyone on Earth was killed, and the remnants of the Avengers couldn't help. He took all the stones, snapped his fingers, and many disappeared, into nothingness. You felt sick, you felt worse, and you collapsed on Tony as he disappeared. He looked at you, trying not to believe it. Five years passed, they met, there was almost no one left on Earth, and he blamed himself for dragging you into all this. They created a time machine, returned to fight Thanos, only now they were all together to defeat him. When their powers were exhausted, portals began to open, people who had disappeared appeared, but many were still missing. For example, Doctor Strange once pulled you from your alternate future with the mercenary Deadpool. In that universe, you moved to another country at 17 and studied for a specialty, and Deadpool gave you tasks. Tony noticed you almost immediately, but you knew little about him, because he was a different you. He came up to you almost immediately and hugged you, you looked at him questioningly, Deadpool snorted: no chzn?
Captain looked askance at Tony, the Avengers had rarely seen anything like that.
