In KH2 Final Mix we see Xemnas talking to Aqua's armor and saying something along the lines of "It's been a long time friend". This seems to indicate that Terra's heart (Could it just be Terra's memories?) may have ended up in Xemnas, but Xemnas himself budded a heart, so I don't see that being likely. MX's plan was to split himself to make more and he found that a heart grew in a person without a heart so with his memories in his nobody he could create another Xehanort. Terra's heart must have went somewhere. Maybe into his armor? We know that nobodys do not have hearts, but grow them. So does anybody have any theories on where Terra's heart is? KH3D doesn't seem to really address TAV besides a flashback and mentioning them a few times.

nobodys = plants lol

As of now, the only thing i know is that Terra's Lingering Will, his armor, only has his mind.

Xemnas has Xehanort & Terra's memories.

Apprentice Xehanort has MX & Terra's heart, along with Terra's body.

 

So yeah, when Ansem and Xemnas were defeated, i think Apprentice Xehanort should have revived with Terra's heart. ( MX Hearts is still inside him, too)

I think the most plausible explanation is that Master Xehanort is the revived Xehanort (given how he literally was the one who all the other Xehanorts were awaiting the revival of), and that the form of Terranort will not been seen again. If this proves true, then it is possible that upon Xehanort's revival, several things may have happened to Terra's heart. It may be inside Master Xehanort, being subdued. It may be in a new body, or have gone to his Keyblade Armour, or may simply be formless like brown-cloaked Ansem SoD. In any case, it can safely be said that (new) Organisation 13 are in possession of Terra, in whatever form he is in, as he is one of the lights MX laid claim to at the end of DDD (the other being Sora before he was saved).

Wow, wow, wow. If terra's heart went back to it's armour...

What if Sora went to search for Terra on the ending?

I know he went to Dream Traverse Town, but on the secret ending Donald and Goofy were waiting for him, probably to go for another journey.

 

Just imagined it: the Tutorial for KH3 being a fight with Terra's Lingering Will so we can talk to his heart, that recently came back inside him.
