New Endgame Theory Suggests That The Secret City Of The Quantum Realm Hides New MCU Villains


Does one particular city in the Quantum Realm hold the very key to the all the new villains who will appear in Avengers: Endgame? Marvel Studios has been avoiding giving away all spoilers about Avengers: Endgame and Kevin Feige had even suggested that all footage used in the trailers and also the TV spots would be only from the movie’s first 15-20 minutes.

One of the leaked toy boxes had hinted that Thanos would not be the only villain in this movie. The reads: “The Asgardian Thor wields the mighty Stormbreaker in his battle against new foes,” and “Rocket teams up with a new crew to guard the galaxy from an even greater threat.”



In the comic books, Chronopolis is known as the stronghold of classic Kang the Conqueror, although it has been associated with a few other time-travellers like Immortus also. It is outside of time in a realm known as Limbo and allows access to many time-periods that Kang has conquered. Every block of the Chronopolis extends to the ends of the planet in the time-period that it exists in. The primitive time-periods are on the outskirts, and the advanced ones are around the centre, and Chronopolis has been dominated by Kang’s Citadel. A few of the comics have shown Chronopolis from the outside – the focus is always on the Citadel. One must note that Kang is unlikely to be in Avengers: Endgame and has ties to the Fantastic Four, and it is known that his movie rights are with Fox.


There are many realms referred to as Limbo in the comic books, but the one that is tied to Kang and Immortus is the most interesting one. It is a very unique dimension and exists outside the time-stream and has no time. Reality has been comprised of a single, moment in which everything that was, and is, coexists. Kevin Feige had explained that the very relationship between the Quantum Realm and time is complicated. Feige had pointed out that the film hints that there are “various levels” to the Quantum Realm. Presumably, this works like a series of concentric circles: and the deeper one gets into the Realm, the more laws of reality cease to apply.

There are two huge points in favour of this very concept. First, Samuel L. Jackson had revealed that Captain Marvel could actually time travel under and it has been known that the Quantum Realm will be featured in Captain Marvel. If the Quantum Realm contains the MCU’s Limbo, then Carol Danvers will pass through it while she travels through time. It is believed that the Avengers will enter the Quantum Realm in the film, Avengers: Endgame for using time travel. If this is the case, then, according to Feige’s explanation they will have to head to the centre of the Quantum Realm which is a Limbo-like reality.


Chronopolis had made an appearance in Avengers: Forever where the Avengers had visited it. Avengers: Forever had revealed that Immortus had served the Time-Keepers, who had seen themselves as custodians of the time-stream and directed Immortus actually destroy and break up the Avengers.


Assuming that the Quantum Realm is the MCU’s version of Limbo, then the Avengers will not only need to enter the Quantum Realm but they need to go to the heart of it, and here, the laws of time and space break down and history can be rewritten.

Unfortunately, this would be the site of Chronopolis, where Immortus is the guardian of the time-stream. Doctor Strange had confirmed that the time-space continuum is very fragile and Wong had warned Stephen Strange that he had been breaking it when he used the Time Stone for experimenting on an apple. One must remember the very first synopsis for the film, Avengers: Endgame-“Our beloved heroes will truly understand how fragile this reality is, and the sacrifices that must be made to uphold it.”

In the comic books, Immortus is served by Phantoms, who have stayed in Limbo and have also become his servants. A few of them are formidable, and during “The Crossing” one of them had torn through a team of Avengers like they had been amateurs.


The Russo Brothers have said that they believe that Avengers: Endgame is a whole new story, one that has been designed to actually celebrate a decade worth of Marvel films rather than honour a comic book run. While he had been asked about recommended reading, Joe Russo had insisted he could not really think of any:

“I don’t think there are any comics that correlate to it,” he had said.

“I think we’re in pretty fresh territory with Avengers 4. If anything, I think it’s interesting after to go back and look at some of the Marvel films and view them through a different lens. But I can’t think of any comics, in particular, that would have value.”

One interesting thing is that this really does fit in well with everything that has been established. Chronopolis is a reminiscent of the Quantum Realm city, and it is not difficult to work out how to tie the Quantum Realm and Limbo together-and it may even make sense to have Immortus play a very crucial role in a time travel movie.
