Xion

Unreleased

Xion is the fourteenth member of Organization XIII, and is to appear in the upcoming game Kingdom Hearts 358/2 Days. At the Square-Enix press conference DK∑3713, she was revealed in a trailer to have strange connections to both Naminé and Kairi. A recent Famitsu article states that she has a "tragic yet, brave fate." Xion has been shown in pain being held in Riku's arms, questioning her existence, indicating that her fate may indeed be tragic. Axel is quoted saying that no matter how often Xion tries to escape, he will always bring her back. This suggests that Xion could possibly be trying to leave the Organization as Roxas did.

Xion's face seems to resemble Naminé's and her haircut is similar to Kairi's. Their resemblance has been underscored by the trailers.

Xion appears to be good friends with Axel and Roxas, and they are often seen hanging out together in Destiny Islands and Twilight Town. She seems to be rather kind, aiding Axel and Roxas in one mission and talking respectfully to Riku at Destiny Islands. She mentions to Riku that she has an important friend, and asks about "that girl who was with Sora," referring to Kairi. Riku tells Xion she "must return to her true self," but she seems reluctant to do so, likely due to her friends. Roxas and Axel both confront Xion in Twilight Town, where she raises her Keyblade to fend off Roxas when he approaches her. When Axel meets her in front of the Twilight Town mansion, she orders him not to go easy on her, and Axel summons his chakrams. Her fate is currently unknown.

Special Abilities
At the Square-Enix press conference DK∑3713, she was revealed in a trailer to wield the Kingdom Key. Although she wields a Keyblade in release trailers, it is unknown if hers is a real Keyblade, as Riku claims Xion's is a fake. Her Keyblade appears to be the Kingdom Key, Sora's original Keyblade, complete with a keychain. Naminé also makes a reference to Xion while talking to DiZ when discussing Sora's memory restoration. Naminé mentions that if those memories begin to "leak" while being connected, and if those memories are connected to other memories, then those "leaked" memories cannot be restored. Naminé then questions if Xion could endure such a thing, confusing DiZ.

Theories
One theory is that unlike Naminé, who is a Nobody of Kairi born from Sora's body, Xion could be a Nobody born solely of Kairi, or a Nobody of Sora born from Kairi's body. The opposing color schemes the two Nobodies have could thematically represent their opposing births. However, Xion's name does not fit the naming scheme of the other Organization members, as it should be an anagram of "Kairi" and "X" if she was Kairi's Nobody. However, her name could in fact follow the naming scheme which Xehanort's does - If the "X" is removed, his name is an anagram of "No Heart". Xion's name easily fits this pattern - for her, the anagram would be "No I", possibly implying that unlike the other Organization members, she doesn't have a somebody. This would also play into the reason why the Organization remains "Organization XIII", even with her in its ranks.

However, this theory does not explain how Xion knows of Sora and Kairi, or Riku's statement that she "must return to her true self", perhaps referring to Kairi. Possibly, Sora's "leaked" memories fused with Xion after the Castle Oblivion incident, explaining Namine's question as to whether or not Xion could endure it.

Trivia

 * Xion is said to have ties between both Kairi and Naminé, suggesting that there is a relation between the three of them.


 * Like Roxas and Naminé, Xion is suspected of having true emotions.


 * In a new scene for 358/2 Days, Roxas, Axel and Xion are seen at Destiny Islands sitting on the paopu tree. Interestingly, their positions mirror those of Sora, Riku and Kairi in the original Kingdom hearts game. Roxas was sitting where Sora was sitting (interesting, as Roxas is Sora's Nobody), Xion was sitting where Kairi was sitting (also interesting, as Xion is said to have "connections" with Kairi) and Axel was leaning against the tree just as Riku was (perhaps implying some kind of connection also; one possible reason is because Axel is best friends with Roxas, as Riku is with Sora, or perhaps because Axel is seen as the powerful member of this trio, and mirroring Riku, is jealous of Roxas, despite his being a nobody).


 * Apparently, Xion possesses no memory of her original self. It is possible she had an unusual birth, like Roxas and Naminé as they both had none of Sora's and Kairi's memories because of their unusual births. However, it is being suggested that throughout the game, Xion appears to regain memories of Sora and Kairi.


 * A cutscene has shown that the other 13 members of the Organization, including those that appeared in Chain of Memories, were present when Xion joined, so it seems that she joined sometime before Sora arrived at Castle Oblivion.


 * Seeing as though Xion and Aqua from Birth By Sleep share the same voice actress, it is highly speculated that they are related in some way.
