Spider-Man: No Way Home has answered many fan questions about who the new villains will be and if they're tied to the previous movie universes. But with each question answered, another arises and only serves to make the film even more mysterious. One aspect that has hardly been discussed is the return of J.K. Simmons as J. Jonah Jameson. But one theory seems to have found a potential answer to the inquiry that places an incredible amount of importance on the character and his reason for being in the Marvel Cinematic Universe.
According to Reddit theorist Humanest_Human, J. Jonah Jameson's presence in the MCU and the other villains in the film are tied to the fact that he's actually a Nexus Being. While it's a loose theory, the idea that Jameson has abilities similar to a Nexus Being could drastically change his place in the universe as it grants the character massive power he's never had before. But fully understanding this theory will take some digging into its details and its characters.
In the comics and the MCU, a Nexus Being is someone with immense power and a connection to the universe and multiverse. As a result, they can open portals and travel wherever they please in known realities. In a way, they are like Doctor Strange's sling-ring in how they travel, but on a much larger scale. However, there can only be one Nexus Being per universe. With Wanda Maximoff confirmed to be a Nexus Being in WandaVision, that means that if Jameson is one, he isn't from the MCU.
Since only one being can exist per universe, this also lends itself to the theory in which the theorist believes this Jameson is ripped from the Raimi-verse. But rather than try to get back, he's instead taken the Bugle name to a new universe and used the era's tech to expand his journalism to new platforms. This explains why he's such a presence at the end of Spider-Man: Far From Home yet wears the same fedora and trenchcoat from Spider-Man 3 in the No Way Home trailer. Nevertheless, he's acclimated well to a new universe, even if he doesn't realize that he's the reason he got there in the first place.
Early in the theory, it also brings up the idea that Jameson is from the same universe as Doc Ock, and they arrived simultaneously. But that is quickly debunked by JJJ's cameo in Far From Home. That being said, if this Ock is connected to the Raimiverse version of JJJ, the Editor-in-Chief's Nexus Being status may have contributed to the influx of villains in No Way Home.
Since no two Nexus Beings can exist in the same universe, that means that there's a more significant possibility for multiversal situations to occur based on the nature of their power alone. Therefore, Doctor Strange casting his spell may have been only a spark to kickstart the multiverse in the Sacred Timeline. Instead, Sylvie's actions in Loki coupled with Jameson's and Wanda's powers created a beacon for No Way Home's villains to appear. Since Spider-Man is such an integral being in all universes, it makes sense that villains like Lizard, Electro, Doc Ock, Green Goblin and Sandman would appear in one world.
With two Nexus Beings in the MCU, this could create enough of a power boost to allow multiple people from various universes to converge. All it would take is Doctor Strange's spell to kickstart everything. Although it's unlikely that this JJJ is from the Raimi-verse, let alone a Nexus Being, the theory does add to the concept that Spider-Man: No Way Home looks to be a massive film for the multiverse. Of course, it may not all make sense, and not all theories will be confirmed. But even if JJJ isn't a Nexus Being, he could still be integral to the story in some capacity.
