Because Roxas is Sora's Nobody.
yes, because since Sora wields the keyblade that means that his nobody also wields the keyblade. Also, another way that Roxas is sora's is if you take out the X in Roxas and rearrange them you get SORA.
Roxas was created when Sora stabbed himself with a keyblade. So, he is Sora's nobody.
Because it was his understanding that Sora and Riku were the only wielders of the Keyblade.
The Keyblade Wielders are Sora/Roxas/Xion,Kairi,Riku, ,Ventus/Vantais,Terra,Aqua,and Master Equas
After Roxas beat her, he absorbed her into himself, obtaining, Oathkeeper and Oblivion.
Roxas would dual-wield the Oblivion and the Oathkeeper, usable in Another side, in Another Story, or when you battle Axle.
I'm not sure. It's supposed to have Sora and Roxas in it, and also The Keyblade Wars!! New characters, new story!! Go to youtube.com to see a video of it. Kingdom Hearts 3 The Keyblade Wars For: Plastation 3
You're most likely referring to the Oblivion Keyblade, which is given to you by Riku (shortly before entering the castle at The World That Never Was).
Xion is a puppet created to team up with roxas so the keyblade's power would rub off on her and then she would get a keyblade... in the long run, to finish kingdom hearts faster...
Roxas was beaten in a Keyblade fight by Riku, who took him to DiZ. Roxas was leaving the Organization. DiZ used a machine to alter Roxas's personality and memories. He was never truly a 'regular boy', as he was in a virtual town created by DiZ for six days.
Yes. An example is Roxas can use "Two Become One", which is "Oathkeeper" and "Oblivion" put together in one Keyblade.
Xion is the 14th member of the Orginization. She, like Roxas, can weild a keyblade. She is also from Castle Oblivion and loses the power to weild a Keyblade (Just for a little.)
