In Ant-Man And The Wasp: Quantumania, Paul Rudd and Evangeline Lilly return as Marvel's tiniest titans. With their extended family in tow, they get shrunk down into a subatomic universe called the Quantum Realm, and come to meet Jonathan Majors' Kang the Conqueror. He's a time-traveling villain who we'll be seeing a lot more of as the Marvel Cinematic Universe enters its next phase.
