Kingdom Hearts II How old is Roxas?

14....is the answer.

 

I see Roxas as being 15-16 like Sora. Which he wasn't actually there he was still a part of Sora.

It would be the the same for Xemnas being whatever age Xehanort was at when the heartless was created.

 

Hmm...it's confusing.

Being 15 years old means living for 15 years, right? Roxas is mentally and physically 15. Sora is 15 (Sora = Roxas, right?). Roxas lived for around 14/15 years as Sora.
Roxas existed as a nobody for 1 year, but is not mentally/physically 1 years old.

Rawr I'm confusing the heck outta myself. I'll go with 15 years old.

 

he was "born" the same age as Sora when he was 14. then a year passed, so he's 15. namine's a little older b/c kairi lost her heart at the beginning of KH1, so she was "born", then some time pasted then Roxas was "born".

 

it's like a counter part or somewhat a twin or something. they are bound to be the same age
