Xion

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 wield the Kingdom Key and to have strange connections to both Naminé and Kairi. A recent Famitsu article has stated that she has a "tragic but yet, brave fate." Axel was quoted saying that no matter how often Xion tries to escape, and he will always brings her back. This suggests that Xion is not in the Organization on her own will, but is forcibly kept a member of the Organization.

Although she wields a Keyblade in the most recent video, it is unknown if her's is a real Keyblade, as Riku claims Xion's is a fake. Her Keyblade from the trailer has been revealed to be the Kingdom Key with a keychain, Sora's original Keyblade. Naminé also makes a reference to her while talking to DiZ, talking about connecting memories.

She appears to be good friends with Axel and Roxas, and they are often seen hanging out together in Destiny Islands. She seems to be rather kind, aiding Axel and Roxas in one mission and talking respectfully to Riku at Destiny Islands.

There is still no confirmation on her powers or abilities, although she's revealed to look and sound like Kairi and have black hair and blue eyes.

A screenshot in a recent Famitsu article shows Xion in pain in Riku's arms, questioning her own existence - indicating that her fate may indeed be tragic.

Trivia

 * Xion is said to have ties between both Kairi and Naminé, theorizing that there is a relation between the three of them.
 * If one were to remove the X from Xion's name, the left over letters can be used to spell "oni", the Japanese word for Demon; or "No I" as an equilant to Xehanort's "No Heart". It is unknown if this is coincidental or not.
