The Significance of The Quantum Realm To The MCU’s Future

The Quantum Realm in Avengers 4

While the Wasp was almost in Captain America: Civil War, the wait was worth it for Evangeline Lilly's superhero. The Wasp gets a number of thrilling actions scenes, showing how Hope's fight training and her more advanced tech makes her a much more competent hero than Scott. Though she suffers Thanos' wrath by the end of the film, we know she'll be back next year and should have a big future beyond that.

Unfortunately, the Wasp isn't in Avengers 4 much according to Lilly. Thanks to the end credits scene in Ant-Man and the Wasp, it's clear her absence is due to her character being killed in Thanos' plan. But with Ant-Man being involved in the fight, that means the Quantum Realm will need to factor into Avengers 4. Not only will Scott need to escape, but clearly some explanation of the Quantum Realm will be involved so the rescue will make sense.

From Captain Marvel to the minds of Tony Stark, Bruce Banner, and Shuri, there's no shortage of ways the Quantum Realm could be accessed. When it is, its vast secrets and source of power will finally be revealed to the rest of the MCU. The Ant-Man franchise keeps things contained, but Stark alone will likely be excited by the possibilities of the Quantum Realm and its energy. In fact, the revelation of alternate timelines and their scientific root could have a massive impact on the plots of upcoming films and TV shows.

Quantum Energy and Phase 4

Set photos for Avengers 4 have teased time travel may be involved in the film, whether through tech, the Infinity Gauntlet, or the time warp teased before Scott goes into the Quantum Realm. Of course, there's other explanations for the images, but with so many heroes dead who have future Marvel Studios movies in the works, something will be bringing characters back to life. The leading theory is that alternate timelines will factor into Avengers 4. We could see the return of certain villains in Avengers 4 due to the multiple timelines, and the re-exploration of the Quantum Realm could see someone like Yellowjacket come back.

With an Eternals movie in the works and the expansion of the cosmic side of the MCU, bringing the Quantum Realm into the main Avengers franchise also sets up a lot of potential. The surface has only been scratched so far, but clearly there's all sorts of alternate dimensions to be harnessed in the MCU. Ghost Rider in Agents of S.H.I.E.L.D. is implied to be powered by one of these dimensions, as is the magic of Doctor Strange. Both Janet and Ghost draw power from the Quantum Realm, and it's easy to hypothesize how everything from the abilities of Asgardians to the Pym Particles themselves could be tied to these other dimensions.

Using that concept, Marvel has an unlimited supply of origins for heroes and villains. If Avengers starts exploring new dimensions, other entities and characters could be discovered that spin into new films. On top of that, opening these worlds could spill over into the main plane and begin granting individuals new powers. From what Kevin Feige has said about the Quantum Realm, it seems it won't just be a location of importance, but rather a source of future stories. New characters, new powers, and new types of narratives could all pour out of these alternate worlds. And by doing so, Marvel can use the ideas in Ant-Man and the Wasp to continue tying all of its fantastical plots back into the sci-fi ideas which have formed the basis of the MCU since Iron Man.
