VANITAS IS AMNESIAC DARKNESS

I think Vanitas is amnesiac Darkness that created a new identity based on his connection to Ven and Sora. His situation would be similar to Apprentice Xehanort, a person who was also amnesiac with two hearts (Xehanort and Terra) that developed new memories until he realized who he was in the end. Marluxia could be another example, other than Apprentice Xehanort.

In the character files, Vanitas said “What do you think I am, to you? Just what the hell do you think I am? I am darkness. And that means you all can be the light. Isn’t that right? And then at the same time, I’m both you and not you”

In his mind, he said that to Sora and Ven.

But also, in the KH3 novel, Vanitas said “I wonder what kind of person the real me. Even that is beyond my comprehension.” —> “However, I do have some memories left within me. Memories from long, long ago. Really, truly, ancient memories. Why do I have these memories?” ——> “Whose memories did that knowledge come from? Was it me? Or Ventus? Perhaps it was a fragment of somebody else's memories.” —> “I don’t know. All I know now is that I must bring my other half back to me. Just who am I? I am half of Ventus. I am...”

Vanitas discovered that he possessed vague ancient memories from X era and he can’t tell if it’s his own, Ventus, or someone else. He was also confused with existence.

Then Re:mind came out. Ventus told Vanitas that they were the same person. A sudden turn happened. Vanitas mocked Ventus for believing that they were the same and said “This may shock you, but we're not the same like you think. I was just hidden deep inside of you, for a real long time. All Xehanort did... was tear me right out of you!”

Even in the Japanese version, Vanitas said that he and Ventus were originally separated existences that was hidden until Xehanort extracted him out.

Me: I wanted to doubt at first until I realized that Ventus had a little amount of darkness inside of him yet was able to produce a new “human” being (Vanitas) that can act like a human but also harbor a power to create species from their negative emotions (the unversed) is sorta weird and fishy. Compared to Sora, who also have little amount of darkness but he only managed to produce a shadow lol

There was no reason for this extra addition detail to added if it wasn’t important and it coincidentally lines up to what MoM said about darkness changing their forms and hiding inside of people. But also, the camera purposely focusing on the eyeball on Vanitas’ Keyblade as he says this.

Me: Now why would Vanitas change or shift his stance about him and Ventus being the same person so sudden? Vanitas used to taunt and call Ventus “his better half” or referred himself as Ven’s “other half” So what happened now? And if I had to guess why his stance change: Because his memories as Darkness resurfaced.

Me: If Vanitas realized who he truly was towards the end like Apprentice Xehanort or Marluxia did, then Vanitas choosing to stay as his “real self” aka darkness but also acknowledging that Ventus and Sora shaped out or defined his existence despite the circumstances, perfectly lines up.
