Okay so this is just a theory unless proven somehow,

 

We know Roxas was created from Sora loosing his heart. We know that Roxas looks like Ven. And Roxas is supposedly Sora's Nobody. But aren't Nobodys usually exact look-a-likes? So wouldn't that make Roxas Ven's Nobody? Maybe instead of Sora's Heart being released, when he impailed himself with the keyblade, Ven's heart was released. Of course(if you think about it) Sora's heart had been more of a neutral force between light and darkness, Ven's heart had forced him more towards light.

 

This would mean that Sora doesn't have a true Nobody, but more of a half of one.

Well Roxas is his nobody but they didnt want the charatcers to look a like but Roxas and Xien are both Sora so i dont know why you are complaining!

xion was was not a real nobody she was just made by the organization with sora memories just for that they can get hearts quicker for kingdom hearts

this is already confirmed vens hearts was release thats y roxas looks like ven

this is already confirmed vens hearts was release thats y roxas looks like ven

 

Really? Didn't know. just thought I was bringing up a newish topic... sorry.

That would be sweet if all of that was true! Then lets say Sora get's turned into a heartless again, and guess who's his nobodies gonna look identical too??? Vanitas!!!!! Ahhhh man I can't wait!!! Well at least not another 4 years!!!!!!!!!

wait...then when sora commited suicide with his keyblade back in KH1, and got a nobody, the nobody looks like ven, but the nobody's name is roxas, so the nobodies usually look like the sombodies though with minor changes in them, therefore roxas may not actually be sora's nobody but ven's nobody, and sora's nobody may be somewhere out there wandering about. Or sora's nobody was destroyed when sora got his heart back with kairi a little while later. But then again namine was formed when kairi's heart was stolen, and kairi already got her heart back then, soooooooooooooooo yeah. Just trying to get things all together here i'm a slow learner.
