That likely explains why Kang the Conqueror is coming for him in Peyton Reed's threequel, and a report shared by ComicBook.com indicates that both Ant-Man and The Wasp will be getting overhauled suits in Ant-Man 3.
Ant-Man 3 does not yet have a release date, but since Marvel now has films slotted through summer of 2022, the winter of 2022 would be the first chance, or even early 2023 considering how release dates keep shifting these days.
As for the release date of the film, for now, it is believed to be dropping in 2022.
Marvel describes Kang as a "menace throughout time, on a journey to become the ruler of the Universe", and the character has also gone by the names Rama-Tut, Immortus, and the Scarlet Centurion. What do you make of Kang the Conqueror as a possible villain?
Either way, that adds a major bit of intrigue to the next Ant-Man, a franchise that's generally been treated as a series of comic sidebars to the main MCU.
Ant-Man helped Earth's Mightiest Heroes travel through time in Avengers: Endgame, and it now seems as if Scott Lang is going to have to pay for his actions.
