Or I just watched Kingdom Hearts Theories all night and then had a random thought at 6 a.m. because my sleep schedule is all outta whack.

This will remain in progress since I might come back to it later if I get more random thoughts.

Anyway, enjoy! And please if you have any critiques or theories to add please tell me in a review.

But please be nice after all "It's just a theory. A game theory!"

Theory: Xion is black haired like Vanitas.

Namine is blonde like Ventus.

Namine's name shares similar meanings to Kairi and Aqua

-Xion is a replica made of Sora's memories of Kairi.

-Xion has black hair like Vanitas.

-Vanitas is Ventus' Darkness.

-Ventus' Heart currently resides in Sora.

-Because of this, Roxas looks like Ventus.

-Roxas is Sora's Nobody.

-A Nobody is a person's body/soul that appears when they lose their heart.

-After fighting Riku/Ansem in KH1, Sora used the Keyblade of Heart (Riku's weapon during the fight) to

sacrifice himself in order to release Kairi's Heart.

-After Destiny Island(s) fell to darkness, Kairi's heart went into Sora's, just like Ventus.

-Now Both Kairi and Ventus's hearts rested within Sora.

-Sora does not know of Ventus.

-When Sora's released his and Kairi's hearts he created Roxas and Namine.

-Namine is Kairi's Nobody.

-When Roxas was created since, it no longer had a body, Ventus' heart went into Roxas.

-This is why Roxas looks like Ventus.

-Since Kairi's Heart was with Ventus' heart in Sora's, Namine's Appearance is similar to his too.

-Xion's hair color could possible be symbolic of Darkness.

-Her hair is also short like KH1 Kairi and Aqua's.

-Now that I think about it Xion's fight with Roxas could also be symbolic to the fight with Ventus and Vanitas.

-Both Xion and Vanitas were created by Xeanort to be vessels/puppets to help summon Kingdom Hearts by obtaining

the Keyblade/X-blade.

-Even though their personalities are different, their goal in the end were the same: Return to the Person you

came from.

-Vanitas from Ventus.

-Xion from Sora/Roxas (I forgot which one)

-Roxas and Ventus both lost their memories of their previous life.

-Xion and Vanitas both take one Sora's Apperance.

-For Xion it's because she's a replica.

-For Vanitas it's because when Ven's heart connected with Sora's the first time, it also connected with

Vanitas'.

-This is why Vanitas looks like Sora.

-Vanitas being Ven's darkness, means he is half of Ventus' original heart.

-After their fight, Vanitas was defeated which should have put him back into Ven's heart.

-For all we know Vanitas could have been in Sora's heart as well because of this.

-Maybe when Sora sacrificed himself, he accidentally split up Ven's heart again.

-Which would explain how Xeanort got Vanitas back.

-I mean any one with common sense could tell Vanitas was going to come back, we just didn't know how.

-Metaphorical 5 bucks says it will be time travel.

-Seriously though, in BBS Vanitas DID return to Ventus because he needed to form the Keyblade.

-And Xeanort released his own heart to possess Terra.

-Then Aqua defeated VanVen or what ever they called themselves.

-Vanitas FADED away, and since he was in Ventus, that could be interpreted as him officially returning to

Ventus.

-Because how could Ven destroy Vanitas if he was already inside him.

-The X-blade is made of light and darkness, but I don't recall it being made of someone's heart.

-I think you just need an excesive amount of both.

-Vanitas mocked Ven saying "if you destroy the X-blade, you destroy both of us".

-But if you look at Ven and Vanitas' "inner battle" from Aqua's perspective, it seems like nohing more than a

power struggle for Ven's body.

-Also if Ven detroyed the X-blade an if what Vanitas said was true, how would Ven be able to go to Sora again.

-Again their fight was a power struggle, so when Ven won he regained control.

-Here's a thought (like what I've been spewing so far), back to the Sora sacrifice thing.

-Ven's heart searched for a light to restore his heart since he lost his darkness.

-What if Vanitas' did the same, but opposite because he is pure darkness?

-This would also explain how Xeanort got Vanitas' heart back.
