2018’s Ant-Man and the Wasp marks the first time a female superhero has headlined a Marvel Cinematic Universe film - even if she has to share the title with a male counterpart. Even those who watched the first Ant-Man, but aren’t familiar with the comics, might have walked away from the film wondering, “Who is the Wasp?”
Of course, the Wasp with whom Marvel fans are most familiar, Janet van Dyne, only appears in that film via flashbacks, whereas the Wasp referenced in the title of the 2018 film is Hope van Dyne, her daughter. The Wasp comics differ a bit from the MCU, and even if you did manage to catch all the Ant-Man easter eggs, there are still some key differences to go over before seeing the July 2018 MCU installment.
The Wasp history goes back to June 1963, when the character Janet van Dyne first appeared in Tales to Astonish #44. She was created by the legendary duo of Stan Lee and Jack Kirby, and she was chosen to be a founding member of their premier superhero team: the Avengers. Janet has remained closely tied to the Avengers ever since, and it looks like her out-of-comic-continuity daughter may be keeping that tradition alive on the big screen.
