How Ant-Man & the Wasp: Quantumania Sets Up the MCU's Fantastic Four

When Disney finalized its deal to acquire 21st Century Fox back in 2019, every fan of the Marvel Cinematic Universe knew exactly what it meant: that it was only a matter of time before the X-Men, Deadpool, other mutants, and the Fantastic Four showed up in the MCU. These days we can practically taste it.

Warning! This article contains major spoilers for Ant-Man & the Wasp: Quantumania and other recent entries in the Marvel Cinematic Universe.

We're currently still waiting for everything to come together, but a Fantastic Four movie is on the schedule for 2025, and there have been teases in a couple places that indicate we might not have to wait until that film to see them play major roles in the MCU. Most notably the appearance of Patrick Stewart as Professor X and John Krasinski as Mr. Fantastic in Doctor Strange in the Multiverse of Madness. While those alternate universe versions of the characters were killed during that film, it's only a matter of time before we get our proper Fantastic Four movie and mutants start popping up all over the place.

Ant-Man & the Wasp: Quantumania took us one more step in that direction, though you may not have appreciated the significance of the moment unless you're an actual comics nerd. The bit I'm referring to is in the mid-credits scene, where we meet the Council of Kangs for the first time as they assemble to discuss what happened to the Kang in the Quantum Realm during the film.

Rama-Tut was the first version of Kang the Conqueror introduced in the comics, in a 1963 issue
