The first Avengers: Endgame release trailer has been online for less than a day, but the theories on how Marvel will connect the 2019 movie to Avengers: Doomsday are already coming in thick and fast. But one fan may have already cracked the code.
"Doctor Doom is the reason Doctor Strange saw only ONE universe where the Avengers won," said Mavel Mania on Twitter, adding that they believe Doom is actually a Tony Stark variant. "One Tony variant could have survived the snap or found another way to defeat Thanos without sacrificing himself. Strange saw what Tony would eventually become and deliberately pushed him toward the sacrifice, preventing the future where Tony became Doom."
