I made a thread recently explaining the possibility of YMX being a developed seed of MX. Going by with that theory, I've come to realize a slightly different scenario. What if YMX's sleeping heart, instead of being part of Apprentice Xehanort's heart, stayed behind with MX's body when MX released his heart? We would have another Roxas case, I'd imagine; Sleeping heart inside of a Nobody, same physique as YMX, etc.
Perhaps another potential seed of MX? Maybe even without YMX's heart in the equation, just MX's (possible) Nobody.
