I think he becomes a somebody at the end of KH2 when he joins with Sora.
In the "world that never was" after the fight with Saix.
sora: his somebody and Ventus: when he realizes that his name is not roxas in KH III
No
Like Roxas, Namine is a nobody and she fused with her to become "whole" like Sora and Roxas
Well his somebody name is Lea. If you notice everybody that is in Organization 13 name has a X in it, all they do is re-arrange the letters and put a X. Ex: Roxas (sora)
Well, you can't reallybecome Roxas, because you only play him once in the entire game. You play as Roxas for the entire first part of the game, which is also the part where he is in the fake Twilight Town. But eventually he has to give his heart or his half or something to Sora so Sora can save the world...again. There will be many other references to Roxas during the rest of the game, and you will encounter him once or twice, but no, you cannot become Roxas after your character has been switched to Sora.
No sora is roxas, well roxas is half of sora, because roxas is soras nobody.
Roxas is Sora's Nobody, so Roxas was referring to Sora as Roxas' "other" part or half of Roxas.
No you can not be roxas if you beat kingdom hearts chain of memories (which is the second one) but you can become riku which has a shorter story and you cant custom his cards but he is really strong.
Yes. An example is Roxas can use "Two Become One", which is "Oathkeeper" and "Oblivion" put together in one Keyblade.
Roxas' real name (his name without the 'x') is Sora.Sora is Roxas' other,and Roxas is Sora's nobody.
Felix Roxas has written: 'The world of Felix Roxas'
Roxas isn't Sora, he's Sora's Nobody.
