About Nobodies, Heartless and Riku
Heartless: thay are creatures who take hearts to feed on the darkness within them.
When an individual loses his Heart, all that's left is the body, this body fades away and is reborn into a Heartless. Where does the Heart go? It is either destroyed and ends up in End of The world, or is preserved within Kingdom Hearts, notably "The Realm of Darkness)
Nobodies: These beings are of twilight, as Heartless are beings of Darkness. When the Heart is seperated from the body, not only is a Heartless formed, but also a Nobody. The nobody resides in The World that never Was and is different from the Heart (which explains why Roxas still exists even when Sora got his Heart back.) While in The World thet Never Was, they possess the names of their true selves.
All members of Org XIII are Nobodies, but their names are based on the names of their true selves with an X to signify betrayal (i.e. Roxas=Sora with an X)
Namine is both Sora and Kairi's Nobody, but her name doesn't have an X nor is based on Kairi's (and especially not Sora's) own name because she isn't a member of Org XIII, she is forced to work for them.
Riku- He was the true wielder of the Keyblade, but fell into DARKNESS. The Kingdom Key, being a keyblade of Light, couldn't be harnessed by Riku then, so it went to Sora, whose Heart still possessed Light.
Riku lost his body to Ansem (who is actually Xehanort, he believes he is Ansem as he lost his memories) And his Heart was corrupted by Darkness, However, King Mickey helped him to fight it using Hope, thus he became a keywielder of Twilight.
^XIIIth Knight, If Xehanort was Riku's incarnate, then his body and heart would be destroyed and his soul would go into a new body and heart. However Xehanort still had a heart. he needed a body, and he chose Riku. He also had a nobody as well, Xenmas, the Superior of org XIII.
^soraandkairi4eva, because a nobody possesses a different physical form, like Roxas' physical form is different form taht of Sora, it is possible Sora can die and Roxas will remain. Org XIII's true selves are possibly gone, having been turn into Heartless most likely, as their creation would mean the seperation of their true selves' Heart and Body .
