In the Nomura interview that i have seen talks about MF what i translated into that MF is believed to be a Nobody. So who's Nobody is he well if you look at the way that i did you see in the interview he stated that this fight is cannon so it takes place right after LOD was destroyed by Master X and right before the Keyblade Graveyard fight. So in term of that who lost there body before LOD was destroyed and before KG. It was Master E if you look at the fight of Terra and Master E he summons a Circle when he summons the chains and balls of light . if you look at the Way MF plays he also as the same summoning Circle when he uses magic and if you see his moves its all the moves TAV uses. so in theory MF is really Master E's nobody. i cant explain the time thing but i just think that's his nobody powers.
