i am the real roxas okay? dont give me trouble i dont feel like
having to deal with this stuff!
Me ( i didnt feel like writing so i got my stuff from the
wikipidea....) 
Roxas
Number XIII
I am Sora's Nobody (my name is an anagram of Sora with the letter X
added.) and i am the newest, not to mention youngest member of
Organization XIII. 
As stated in the Secret Ansem Reports, I was born when Sora stabbed
himself with the Keyblade forged from the hearts of six of the seven
Princesses of Heart in order to free Kairi's heart at the cost of his
own. But Sora's time as a Heartless was short, as Kairi's light had
fetched Sora's heart from the darkness, restoring him to his former
self. Thus, Sora and I co-existed, but I would be without his true
memories, and we were incomplete without one another. Even so, my
status as Sora's Nobody granted me the ability to use the
Keyblade.(cool huh?) This, along with my emotions, make me a very
unusual Nobody. 
I, having been born in Twilight Town, is soon discovered by Xemnas,
and is given my name.(noooo!!) Having nowhere else to go, I joined
the Organization in hopes of finding the answers he needed. On that
same day, I meets Axel( =D ), and we soon become best friends. 

Even so, I was growing increasingly impatient for the truth about
myself, even as i use the Keyblade (though i does not know why i can
wield it) to bring the Organization closer to their goal of attaining
Kingdom Hearts. 

Eventually, i becomes fed up with recurring dreams of Sora, the other
self i didn't know, eventually deciding to leave the Organization to
find Sora and know who these people i didn't know were. Axel, who
knew Sora's whereabouts at the time, intercepts me and tries to
convince me not to go through with it, warning me that the
Organization would destroy me if i betrayed them. However, I remained
indifferent, and continued on, leaving a dejected Axel behind. =X
