Iron Man is one of the most pivotal superheroes in the Marvel Cinematic Universe. Heck, there would be no MCU without Iron Man, as it was his first movie that launched the franchise back in 2008.

Why do the Avengers need Tony Stark? Well, apparently, Iron Man has the knowledge necessary to destroy Kang’s best weapon, the Time Chair that we saw in Ant-Man and the Wasp: Quantumania.
