The first look at the Quantum Realm in Ant-Man and the Wasp: Quantumania might confirm a huge Kang the Conqueror theory. Thanks to the release of the first Ant-Man 3 trailer, audiences finally can catch a glimpse at the sequel's story and use of Kang. The footage reveals the Ant-Man team returning to the Quantum Realm for another adventure, but this time they will encounter Kang the Conqueror during the visit. Ant-Man 3's trailer is heavily focused on the Quantum Realm and Kang, and it may have confirmed a popular fan theory about Jonathan Majors' villain in the process.

Following the release of Ant-Man and the Wasp and the Quantum Realm's role in Avengers: Endgame, theories began to link Kang to the Quantum Realm. This included a popular theory that the Quantum Realm was inhabited and even included a secret city that could be Chronopolis, which is Kang's main base in the future where he oversees all the realms he has conquered. Fans continued to connect the dots that the Quantum Realm could be the home of Kang as a result. Thanks to Ant-Man and the Wasp: Quantumania's trailer, it is now officially confirmed that Kang resides in the Quantum Realm, so the theory could be right after all.

Why Is Kang The Conqueror In The Quantum Realm?

The confirmation that Kang the Conqueror is in the Quantum Realm in Ant-Man and the Wasp: Quantumania does not come with an explanation for why he is there. The MCU's only previous use of Kang was with He Who Remains in Loki, which indicated that his variants were all defeated. The Sacred Timeline branching out creates a path for Kang to be in the Quantum Realm, but it is unclear if he is there by choice. It is possible that He Who Remains managed to trap the real Kang the Conqueror in the Quantum Realm. He might not be as big of a threat to the multiverse in this place, even if it gave him the ability to create an army.

One other potential explanation for why Kang the Conqueror is in the Quantum Realm is due to its incredible powers. Avengers: Endgame revealed that the Quantum Realm can be used for time travel, while Ant-Man and the Wasp teased the powerful Quantum Particles. It is possible that Kang has made the Quantum Realm his base of operation to try and harness its unique qualities and powers. Since Kang's plan is to conquer the multiverse, he could potentially figure out a way to use the Time Vortexes and Quantum Particles to travel to other universes. The MCU has barely scratched the surface of the Quantum Realm, so new discoveries are certainly possible.

Can Kang Leave The Quantum Realm?

Based on Ant-Man and the Wasp: Quantumania's trailer, it is possible that Kang cannot leave the Quantum Realm on his own. That could be why he appears to bargain with Ant-Man and offer to help him save his family. Kang could be trapped in the Quantum Realm against his will, but the Pym Particles have proven to be the key to escaping it. Ant-Man and the Wasp: Quantumania's story could revolve around Ant-Man agreeing to help Kang escape the Quantum Realm in exchange for his family's safety. If that is the case, Ant-Man could be directly responsible for the destruction Kang will bring to the MCU in the Multiverse Saga.
