Marvel MCU rambling; spoiler? Show more
Captain Marvel was marvelous.
The subtitle The First Avenger implies a chronologic order to the heroes. Pym era Ant-Man and Wasp would be 2nd/3rd, and by rights of tech hero inheritance, so too their successors, maybe? Captain Marvel is 4th. Iron Man likely 5th. (Barring further retcons, such as 60s F4, my fanon.)
It's weird that Endgame is the first team up of even four of the first five then. Also, a shame that either Wasp likely not in the team up.
