Iron Man, AKA Tony Stark, warns about the consequences of time traveling in Avengers: Endgame. The introduction of Kang the Conqueror and his variants will pay that line off.
Iron Man warns about the consequences of time traveling in Avengers: Endgame and Kang’s introduction in the Marvel Cinematic Universe promises to pay off for that very warning. In Marvel and Disney+ series, Loki, Jonathan Majors appeared as a Kang variant. He is also expected to make an appearance in 2023’s Ant-Man and the Wasp: Quantumania. But it is yet unclear that whether or not he will make an appearance before that. There are various Marvel and Disney+ shows that have been released post-Avengers: Endgame but one line that Tony Stark echoed will get a major payoff in the future.
When Ant-Man returned in Avengers: Endgame, he brought an idea that how time travel could make things turn right. While the film had multiple allusions that included time-traveling, the same could have many unintended consequences as well. With that said, it was Tony Stark who provided the final key to conduct a safe time journey, but when Avengers traveled through time, they allowed Thanos to return and attempt his Snap. His arrival destroyed the Avengers base and in the aftermath, Steve asked Tony, “What happened?” to which Tony responded, “You messed with time, it tends to mess back. You’ll see.”
The invention of time traveling in Avengers: Endgame will have much larger consequences in the Marvel Cinematic Universe. Their time traveling to 2012 spawned Loki who continued to play himself in the Marvel and Disney+ show Loki. There, with the help of Sylvie, Loki managed to reach Kang who portrayed himself as “He Who Remains.” As Sylvie killed Kang in the season finale, the consequences traced back to what Iron Man said in Avengers: Endgame. He Who Remains’ death spawned the multiverse that will now make Kang variants the central part of the MCU Phase 4 and maybe much beyond. This proved that Tony Stark was right: Sylvie and Loki messed with time and now it would rebound itself in a way that is proportionally fitting.
While the assumption could be what Iron Man said was a moment of foreshadowing his death, it is really a setup for something larger in the Marvel Cinematic Universe. Because Thanos already entered the timeline by the time Stark echoed the line, his warning was perhaps a little late. Apparently, the idea of time traveling had some unintended consequences that set up multiple characters and gave them a portal to enter and affect the sacred timeline as well.
Thanos’ arrival in Avengers: Endgame was uncertain but it was Tony Stark who traveled through time, created the alter-actions of Loki that led to the arrival of the Kang variants. Throughout Tony’s tenure in the MCU, he has spawned many villains by doing the right thing. And that is why it is fitting right that the man who started it all with Iron Man will be having an aftereffect on the MCU, even after his death.
