Teeny Tiny spoilers at the beginning of this, but it is necessary for my theory. If you don't want to spoil Kh: ReCoded for yourself, then leave, generally since what is in the spoiler tag is the reason for me making this theory.
It has been somewhat confirmed by Nomura that there might be multiple forms of Xehanort in an upcoming game, which was suggested in ReCoded's secret ending. This makes many things possible to happen. Many things.
Recall that in BBS, MX released his heart with his Keyblade and sent it into Terra's body. During the time that MX's heart was out in the open, his body was glowing with light, and once he had seen that what he was planning to do with it was fulfilled, he faded away into orbs of light. To refresh your memory, here is the cutscene:
Did something like this happen before? Ok technically after, but it did happen. Where did it happen you might ask? This same thing happened with Sora. Recall that he took the Keyblade of People's Hearts and stabbed himself with it, releasing his heart and Kairi's heart as well. Remember during that time, he was glowing with light, and then after he saw that Kairi's heart had entered her body, he faded away into orbs of light. See a connection? Recall that Sora created a corresponding Heartless and Nobody, his Heartless appearing on site, but his nobody taking form in Twilight Town. Perhaps this happened with Xehanort?
Right now you might be dismissing this, "That is not at all possible, considering that Heartless appear on site of a person loosing his or her heart, it can't be, as there was no Heartless on the cliff." And how right you are if you thought that. There was no Heartless, because MX's heart entered Terra's body. Does it necessarily mean that even though there was no Heartless, that there can't be a Nobody? After all, the Nobody is the body of the person, and it is definite that the Nobody doesn't actually appear at the place that it was created. So perhaps there may be a Nobody we don't know about. His body was left behind after all, and no one generally knows what happened to it.
One possibility could be the person we don't know anything about. The Mysterious Figure. This is not directly part of my theory, but rather just a suggestion. Considering what was said in the spoiler tag, this may be one of the many 'forms' that was talked about. It might be possible that this is the Nobody of MX, but not too likely, as MX is a little more frail than MF, but it is still possible, after all, MX doesn't show too many signs of being that frail, and his figure does seem to resemble MF when they appear in the black coat. To prove it, I will show two videos:
They do have similar body builds do they not? Also bear in mind that MF has blades similar to Xemnas' Ethereal Blades. This shows a definite connection between the two. Perhaps the Ethereal Blades are a factor influenced by MX? However, this is all just speculation as to who MX's Nobody could be, if I am correct in assuming he has one.
