Kingdom Hearts 4's Story Could Be More Yozora's Than Sora's

gamerant.com:

Even after years of Kingdom Hearts games, there's a lot of ground for Kingdom Hearts 4 to cover. For as much as Kingdom Hearts 3 was dedicated to resolving the many plot lines running through KH up to that point, it also set up tons of questions that only a sequel could answer. The Black Box and the role of the Foretellers are two big question marks that will play into the upcoming Lost Master Arc. Sora's current location of Quadratum is another mystery, both in how it connects to other worlds in its own reality and how it relates to the usual one.

However, all of these pale in comparison to the most blunt teaser that Kingdom Hearts 3 could provide. Yozora, the protagonist of the fictional game Verum Rex seen in the Toy Story world, is real and connected to Quadratum. Furthermore, in the Kingdom Hearts 3 ReMind DLC, Yozora fights Sora with the outcome being either Sora frozen or Yozora fading away before waking up in a car. It's not clear how this relates to Kingdom Hearts 4’s trailer showing Sora waking up in Quadratum, but there's a good chance that Yozora will be heavily involved in Sora’s adventure.

What Yozora's Final Fantasy 13 Reference Could Mean for Kingdom Hearts 4

There's a lot that fans don't know about Yozora, and it seems like his entire character was designed to facilitate questions. For one, he allegedly isn't even in his right body. According to the Nameless Star found in the Final World, Yozora's heart is not his own. What this means isn't clear, but hearts being transferred between bodies is something that's been going on since the first Kingdom Hearts. This and the Nameless Star’s lack of an identity implies that the villains’ usual heart-based machinations have been going on in Quadratum already.
