Birth by Sleep -Spoilers- Foresight unto Darkness: The Mystery of No Heart

Very interesting theory. I havent even really thought of that, and I cant find any flaws. All it really needs is to be proven or not. Good Thinking!

 

Hmmmmmmmm. When it comes to his moves. We can say from a game designer point of view, yes his dash move is based off Terra's. However, We as a story perception know absolutely nothing of Xheanort, when he was younger: battle style, moves, ect. Perhaps in his youth he fought like Terra. As for the keyblade, Terra's armor in FM also keeps it's keyblade,. If you have seen the no heart battle, the key blade has a life bar, showing evidence that the keyblade is alive. And though it wielder's body perishes, as long as it holds some connection to the world (armor) The keyblade will be able to be summoned It is about the memory of summoning the blade. Xion went through a similar issue. That is all I will say for now. I'd love to post again if I find more.

 

Xehanort's keyblade is made of a heart, the dark blade Riku used in KH1 was made of 6 hearts. I do not know if these are exceptions, but again Nomura hasn't ever come out and told us exactly what makes a key blade. For all we know they could all be of hearts, and we wouldn't know it.

 

I thought it was Xehanort's Lingering Spirit, like how AotM was Eraqus's Lingering Spirit.

Keyblades are an entity of their own IMO. Remember, they were made to open Kingdom Hearts, so my guess it was made by hearts.

 

It's possible that he did not discard it but found a way to animate it for evil purposes. Remember he said that he had many doors to choose from and that Terra was only one of them. He could have it out doing evil for his return.

 

I think it said in a report somewhere in one of the games that all keyblades are either made of Light, Darkness or hearts- the later is the rarest so it's possible.

Considering Xehanort= No Heart X as an anagram then this theory makes sense. It would also explain why Xemnas uses it later in KH2.

In this picture:

Spoiler

No heart does have a different battle stance to MX but he retains the keyblade just like Terra's lingering sentiment does.

 

We actually DO have a good source for how Xehanort fought when he was younger. Terranort, if memory serves, uses many moves commonly used by Terra, including a Darkness enhanced Dash move, Solo Arcanum, the Dark Impulse finisher and several of its moves, and a far more powerful version of Meteor. It can be easily inferred that Xehanort's style was similar either by coincidence or that Eraqus based Terra's training on young Xehanort's style. This really only serves as more proof of your theory.
