True there is no correct answer but you can guarantee that it's not being animated by terra's soul. If Terra had lost his soul his body would've died, simple as that.i suppose there isnt really a correct answer until nomura actually says what it is but i always saw it as a suit of armor being animated by terras soul
but this thread isnt about the lingering will. what do you guys think about the whole guardian being terras heartless theory?
Personally I like the theory that it could be Terra's keyblade enacting on his will to stop Xehanort and protect Ven and Terra. It'd be in line with terra's "mind resisting" since ones will is an aspect of the mind and it'd be him resisting MX through his keyblade.I think it's terras darkness manifested into a weapon. It has feelings, and I suppose a heart based off of that split second of "pain" it looked it was feeling.
