Hindsight Bias (смешанная)

"And I... Am... Iron Man." Tony snaps his fingers and welcomed death with open arms. Instead, he finds himself waking up to a voice he never thought he'd hear again, the press of something hard and metallic against his chest serving as a wake up call in this new world.
During the events of Endgame, Tony gets a hold of the infinity stones and sacrifices himself to save the universe from Thanos; except he wasn't expecting to wake up thrust 13 years into the past. People liked to say that hindsight is 20/20, and Tony, well Tony's never been one to look a gift horse in the mouth.
No pairings at this time, not sure which direction that'll go yet.
