Ant-Man and the Wasp: Quantumania

During her days of entrapment in the Quantum Realm, Janet van Dyne encounters an exiled traveler named Kang. In the present day, after the Battle of Earth,[a] Scott Lang has become a successful memoirist and has been living happily with his girlfriend, Hope van Dyne. Scott's now-teenage daughter Cassie has become a political activist, resulting in her spending some time in jail before being bailed out by her father, whom she has become estranged from since he started focusing more on his celebrity status than his duties as Ant-Man. While visiting Hope's parents, Hank Pym and Janet, Cassie reveals that she has been working on a device that can establish contact with the Quantum Realm. Upon learning of this, Janet panics and forcefully shuts off the device, but the message is received, resulting in a portal that opens and pulls the five of them into the Quantum Realm. Scott and Cassie are found by natives who are rebelling against their ruler, while Hope, Janet, and Pym explore a sprawling city to get answers.
