Xion is the imperfect replica/clone of Sora created from his leaked memories by Xemnas as a fail-safe in case Sora proved to be useless to Organization XIII's plans. As Sora's memories are the basis of her being, Xion resembles Kairi, who is Sora's strongest memory. During her time in the Organization, Xion closely befriends Roxas and Axel, but she eventually leaves the Organization as she develops more of Sora's traits in conjunction to Naminé's attempt of restoring Sora's memories. Eventually desiring to be the real person, not caring if Sora ever awakens, Xion came to the conclusion that she would become whole if she absorbed Roxas, Sora's Nobody, and attacked him. However, Roxas absorbed her instead, gaining use of her Keyblade which results in his signature fighting style - duel wielding.
KH 358/2 Days came out 2 days ago in Japan.
Xion = Xarmy Sue since her addition to the series was unnecessary and her "identity" is a big cop out.
Just the fact she was never mentioned in CoM, KH II, KH II final mix, the mangas or the OFFICIAL novel is enough evidence to label her a mary sue that came from KH fanfiction.
Roxas x Xion = Incest or Masturbation just like Sora x Roxas.
All the supporters/lovers/fans of Xion who didn't wait till the game came out before quickly deciding she's awesome, you like her, OMG RokuShion is canon and etc you're ALL hypocrites.
All the ppl out there who screamed at others for hating Xion or just having an opinion on her based off the stuff NOMURA LEAKED OUT yet didn't say one word to the supporters/lovers/fans of Xion who was loving a character THEY ALSO DON'T KNOW ABOUT, are as terrible as the AkuRoku haters.
And lastly, to all the ppl who were defending this b***h just because others saw Xion as the Mary Sue she truly is... obviously YOU DON'T know the real definition of a Mary, how it applies or even the ******** subtypes out there -_-
KH fandom is epic failure because it harbors a lot of idiots who'll rush and protect a new character JUST because she has ovaries and is a creation of Square Enix.
