Remember in BbS, how when you fought the Unknown, he had Saix's model. Well, since Isa is one of Xehanort's vessels, perhaps the unknown was actually Isa after becoming a full Xehanortian vessel. And i know Nomura said the unknown was YMX, but if you think about it, if it's after Saix was infused with MX's heart, technically, he would be YMX. Thoughts?

if it's after Saix was infused with MX's heart, technically, he would be YMX.

No...

We have Saïx with a piece of Master Xehanort's heart inside him. How does that suddenly equal Young Xehanort? Also, how did Saïx acquire the ability to time-travel all of the sudden?

i haf to agree with JTD95

This was a basic "I'm bored" post, so ignore this topic.

That word, Xehanortian... I LIKE IT!!

I think YMX and Isa are completely different person. Models doesn't say much anyway.

No. Technicalities like models have no larger meaning. The Mysterious Figure model in BBS was simply a place holder. It's the same model that appeared to Sora as Xemnas in Final Mix and its the same model Marluxia used in the original CoM before the remake.
