well, all i can say is, its definatly not MS...i mean if it where it would be kinda ghey..

besides we new he could develope it further because he did it when he was a child,....he changed it from two toma's to three toma's..fact is why can't he develope MS well i thought that had to do with being a HIGHER up of hte bloodline..but in a since he did kill his best friend..more or less let him die. so sure why not..he finally figured out a way to activate a sub form or different form or a altered form of MS..but definatly not MS .unless it looks different in all eyes. PERHAPS obita was a Uchiha elite.
