On 30th of May 358/2 Days was released in Japon and it answerd the question about who Xion is

*Spoilers start here*


She is not actually a Nobody, but a doll created par Xemnas from Sora's leaked memories. Her face was based off of Sora's strongest memory, Kairi, but as Naminé pieced together Sora's memories, she began to physically look like Sora.

The plan was for Xion to eventually become a complete Sora replica, due to the fact that Xemnas was unsure if he could rely on the actual Sora to gather him enough hearts for Kingdom Hearts. Eventually she would have had to absorb Roxas to become whole, and if that were to happen, the original Sora would never awaken. Eventually she is absorbed par Roxas instead, thus giving him the ability to duel-wield.

*Spoilers end here*

In my opinion a completely original storyline.

What do toi think

Hint 1: (Namine) "Roxas, do toi remember what your true name is?"
Hint 2: Roxas cried at Xion's ending moments

Point Out: "True name" she is referring to Ventus, Roxas' original being before his cœur, coeur was put to sleep within Sora par his choice.
Point Out: Ventus' cœur, coeur was separated from Sora and put into his Nobody.

question for BBS: If Ventus saw what Vanitus looked like before Ventus was possessed the why stay with Sora?

question for BBS: Vanitus has two Kingdom Keys fused and equipped with a spear? Why?

Point Out: Both Sora and Ventus could use the Kingdom Key but within Ventus' body the dark key has been removed of all traces of darkness around it. (Ventus seems to be Sora's good half...)
