Let's have a moment here.
I've looked at what fans have dubbed "Xion" (which sounds like a Nobody Eevee evolution or somethin')
What the christ? Are you guys seriously upset that AXEL HAS OTHER FRIENDS?! God damnit, are you all forgetting this is a mix between DISNEY AND SQUARE. Of course ridiculously weird touchy feely BS is going to come wafting in! GET THE FUCK OVER IT!
And are you honestly thinking Xion is a mary sue?
OK yeah she's got some traits to that.
14th member, key blade wielder, Roxas BFF
...OK, honestly I can't be the only one that sees it.
OK FINE. Let me share with you my power of COMMON SENSE ESP.
BIRTH BY SLEEP: THE ENDING IS ROCKS FALL, EVERYONE DIES! MICKEY BEATS THE FINAL BOSS! BALDSEM'S SOUL POSSESSES TERRA TO TURN INTO XEHANORT OF KH 1+2 THUS MAKING HIM XEMNAS' SOMEBODY. VEN IS REBORN INTO SORA. AQUA GETS THE NORMAL ENDING OF EVERY OTHER GENERIC PERSON, HEARTLESS GET HER AND A NOBODY IS MADE!
XION IS OBVIOUSLY AQUA'S NOBODY! OF COURSE SHE HAS A KEYBLADE, OF COURSE SHE'S ROXAS BFF, AND OF COURSE XEMNAS (WHO IS XEHANORT'S NOBODY=HE IS TERRA'S NOBODY) IS GOING TO MAKE HER A 14TH MEMBER! IT'S ALL ABOUT RESIDUAL MEMORIES! DID YOU NOT PAY ATTENTION TO THE CUTSCENES IN FINAL MIX+ WITH AQUA'S ARMOR?
And you know what else? Just to fuck with you all even more?
I BET AXEL'S SOMEBODY/HEARTLESS IS MCCREEPY HELMET! AND HE HAS DARK GREEN/TEA COLORED HAIR TO KEEP WITH THE RUNNING GAG!
THE END! ENJOY YOUR SPOILERS!
Besides she can't be a mary sue made to steal away "AXEL'S PRECIOUS ROXAS" anyways:NAMINE ALREADY DID THAT.
Edit: Yeah turns out I'm a retarded fuck weasel and she's just Sora's leaked memories from COM given form- SORRY EVERYBODY.
...You fangirls are still douches about it originally though.
