Alright, this is my first theory so dont be cruel.
My idea is that the MF is Terra fading through time.The idea is that after Xemnes and Ansem SOD were both defeated insted of xehnort coming back both terra and MX come back seperatly, but instead of coming back in the present they are sent to the past and begin to journey through time in the way Bruce Wayne currently is in the comics and will eventualy come back to the present. Terra battles each of the apprentices to make sure they are strong enough for the task ahead and uses sabers (which he learned to use from his memories as xemnes) to hide his identity.
This is my theory, comment, judge, debate.
