Vanitas took over Xehanort, and now all the "Xehanorts" are really Vanitases. You might be wondering how I came to this theory, and be arguing it simply isn't possible. So, lets start off with what sparked this theory.
A specific scene in DDD.
[#37 | HD Unsubbed] Out There - Kingdom Hearts 3D [Dream Drop Distance] - YouTube (it is queued to the proper time)
You see Vanitas manifesting next to Young Xehanort, almost as if Vanitas was speaking through him. But this is the only time we saw Vanitas as a part of Xehanort right? Wrong. The trailer for BBS in KH II FM+, we see a transparent version of Master Xehanort separate from himself and become Vanitas. Kingdom Hearts II Final Mix cutscene: 16 - Birth by sleep - YouTube
Another reason why a version of Vanitas might be inside Xehanort, possibly being the real antagonist.
Now that I said what led me to this theory, how could it be possible? Especially since Xehanort created Vanitas much later in Xehanort's life span than he was in that scene in DDD. But I ask you this, Wasn't the theme of DDD time travel? One of the rules being: "You must leave your body behind." Well that would be easy for Vanitas, for I am not sure he officially has a body. "There must be a version of you waiting at the destination." Well the line, "My future self gave me a task." could mean a Xehanort traveled back in time, and if Vanitas took over that future self, he could then travel back and take over Xehanort. Still it is entering nasty paradox waters... Either way that is the only way I could justify it happening.
Here is a link to where he says the rules of time travel. #163 | The Past Xehanort - [All Cutscenes - No Subs] Kingdom Hearts 3D [Dream Drop Distance] - YouTube
So, what do people here think about this theory? Honestly, I both doubt it is true, and I hope it isn't true. But...I have this feeling that it might happen just to give us one final twist...
