Roxas

Roxas is Sora's Nobody (his name is an anagram of Sora with the letter X added.) and the newest, not to mention youngest member of Organization XIII, though while he was in the digital Twilight Town created by DiZ he was unaware of this for a long time. He was created in Kingdom Hearts after Sora battled Riku/ Xehanort's Heartless. (This was at the point when Sora thrust Riku's Keyblade into his own heart to release Kairi's, although this turned him into a Heartless. He was later changed back by Kairi herself. Roxas has no memory of being Sora but does begin to have dreams about him at the beginning of Kingdom Hearts II, when he is a playable character and Sora's memories are returning, thanks to Namine.

In battle Roxas wields two Keyblades, the Oathkeeper and Oblivion. He controls the element of light and the Samurai Nobodies, possibly due to his acrobatic nature - fans will notice that when he duels with Sora he performs many more stunts than the other Members ever do or, possibly, are capable of (excluding, perhaps, Xemnas who is able to jump to the top of Memory's Skyscraper. However, Roxas and Sora are both able to run up its walls).

He is, apart from Axel, the only Organization member fought by Sora without Sora being controlled by the player - instead there is a cutscene showing Sora fighting and defeating Roxas, whereupon Roxas remarks, "You make a good other" and vanishes.

Roxas has a close relationship with Axel, and it has often been questioned whether they are more than just friends.
