Roxas is Ventus's Nobody because when Sora loses his heart, his body is used to make xion. Ventus is sitting, lost because his mind & soul are in Roxas, also, when Sora loses his heart, because Ventus merged his heart with Sora's, remnants of Ventus's heart were all that was left, which went into Roxas, giving him most of a heart. The reason Ventus's body isnt used is because there is no darkness in his heart, so the same thing that happened with Namine and Kairi happaned with Roxas and Ventus. That's why both have the semblance of feelings.Finally, all nobodies (except Namine and Xion, but technically neither of them are nobodies)look like who they are nobodies of.

 

Either that or he's both their nobodies.

Sora didn't have a real body he merely had a human like shell created by Kairi.

That's freaking awesome. Lol he defeated Ansem Seeker of Darkness without his real body. Nice. Although Having a fake body probably didn't hinder him at all but it's cool to think about.

Roxas is indeed Sora's nobody as he is made up of Sora's body, soul, and also retains Sora's memories. One of the famous scenes is in KH2 FM and KH 358/2 Days where Riku says "Come on Sora, i thought you were stronger than that" Roxas instinctively reacts by saying "Get real, look which one us is winning". 

 

However, with some help with Tetsuya Nomura. He confirmed that when Roxas dual wields, he isn't wielding Xion's fake keyblade, in reality he is wielding a keyblade that was awakened from inside him. Which is suggested to be Ventus. Another confirmation was that the reason why Roxas fainted was that the heart inside him was getting to close to Ventus's body and soul. 

 

So lets just be clear: Roxas is clearly Sora's nobody. however due to Ventus heart inside Roxas, it affected his appearance and also allowed him to dual wield (and in turn Sora in kh2).

Roxas: A being of darkness known as a nobody who harbors Sora's body from his heartless split whilst retaining Ventus appearance as Sora had three hearts inside of him as opposed to one (with the female heart of Kairi gaining elements from Ventus' apprentice in order to form Namine).

 

Vanitas: A being of darkness known as a unversed who projects the appearance of Sora due to Ventus' dark part of his fractured heart being healed by Sora.
