This theory was originally developed by derekscorner and revised last night. I delve into the theory a little bit myself and came up with something pretty incredible. Again, most of this theory is in credit to derekscorner. All I’ve done is branch it out a little more. You can read the original post along with what I came up with here.
Kingdom Hearts is never entirely clear on how it’s universe works. The only trustworthy information you can get is spoken by characters in cut scenes, usually rather vague and said with symbolism, or it’s hidden somewhere in the “Reports” you recover throughout all of the games.
Because of this, the game can constantly flex it’s rules to bring about more scenarios and fix discrepancies it might have had in the past. But assuming, with the release 1.5+2.5 for the PS4, all of those discrepancies were fixed and the game is official, theories about this game will now become all the more relevant. And sensible.
Most things in Kingdom Hearts can be explained away in a rather convoluted essay. However, there are still select few scenarios that fans can’t seem to tackle because it wouldn’t make sense for how the game’s universe operates. One of these leading scenarios is the issue of bringing the lost Nobodies back into existence. I’m talking about Roxas, Naminé, and Xion.
