^ Ant-Man and the Wasp: Quantum Fever's ending has major implications for Ant-Clan, Kang the Conqueror, and the MCU Multiverse. Jonathan Majors cemented the concept of the MCU Multiverse as He Who Remains in Loki, and now he's giving it a new twist as Kang the Conqueror in Ant-Man and the Wasp: Quantumania. Although the third Ant-Man takes place primarily in the Quantum Realm, its events could have implications for the entire MCU when Avengers: Reign of Kang and Avengers: Secret Wars bring back the Major's evil mutant chain reaction.

Kang's loss, though, might just be the calm before the storm, something Scott Lang already suspects. Here's how Ant-Man and the Wasp: Quantum Fever ended and how it sets up the future of the MCU.
Kang the Conqueror is an almost invincible villain. His power is enough to destroy the entire timeline And defeat the Avengers of the parallel universe alone. However, Kang sabotaged his own efforts by underestimating his opponent. After defeating Ant-Man and his family, Kang left most of them to fend for themselves while capturing Janet Van Dyne.

But it could also be the first step in creating technology to help the Avengers travel between universes.
