MCU Phase 4: 15 Essential Rumours & Theories You Need To Know

13. The Quantum Realm Will Play A Massive Role

The Rumour:

The Quantum Realm, last seen in last summer's Ant-Man and the Wasp, is expected to play a massive role in Avengers: Endgame and an even greater one after that, with many having posited that the realm will open the gateway to an entire microverse of different characters and stories. Multiple outlets have led with this story, but MCU Cosmic's Jeremy Conrad has repeated it more than most.

Apparently the Quantum Realm will first introduce the character of Black Knight in Endgame, before being expanded upon massively throughout Phase 4, opening the door to dozens more characters and concepts in the process.

The Response:

There's no way of telling if the Quantum Realm will have a part to play after Endgame, but a consensus has developed in recent months arguing that it will be at the centre of Marvel's plans going forward. Only time will tell if that does indeed prove to be the case, but this actually ties into another rumour pretty nicely too...
