Believe me, I could believe that it's Young Xehanort. In fact, I speculated that. But my point isn't that you're wrong, it's that you could be wrong. Were looking at someone who's appearing in another realm, has the ability to bring back dark beings, and bears some connection to Xehanort. Practically ANYTHING could happen with this guy. Also, we don't know what Terra's age is, but I can guarantee that he's likely eighteen-twenty-one. Him getting younger to that height doesn't seem that big of a deal to me.it can happen but i don't think it will be THAT big of a change. you continue to say on appearence this and that
Sora and Riku didn't young down 10 years. That's a big pretty damn difference. "Terranort" "Xehanort-Apprentice" looks to be in his early - mid 20s
this young guy who looks more like young MX anyway looks in his teen years. and he's barely as tall as Vanitas while "Terranort" is a foot taller than Vanitas so yeah...
By the way the 4 bangs falling down from his face looks like young mx all the way. Why? because ripped from the game of BBS you see Young MX had 4 bangs falling down from his face like apprentice xehanort. also you can tell when he turned his head he had 2 bangs on each side just like this guy.
im positive this is young MX or someone else but NOT Terranort. at all.
To sum up, I still think it COULD be Young Xehanort or COULD be Terra-Xehanort. But don't act like this is completely set in stone because judging character appearances in video games tends to not end well most of the time. There is a BUNCH of reasons that I could list that this could be Terra-Xehanort, but I'm not going aroung and acting like he's practically confirmed.
