Sora and Ventus Relations? (KH2 Spoilers)

Are Sora and Ventus somehow similar? Kingdom Hearts II showed many parts of Sora and Roxas looking similar face-wise. Although when Organization XIII talked about it, they were messing with Sora, but when Pence asks if he saw Sora before, it may mean that Roxas and Sora have a similar face structure. Also mostly in KH2's ending when Sora's face transitioned to Roxas's.

AND, because Roxas and Ventus have literally the same hair, face, and voice, are Sora and Ventus related in some way? I know the question seems random, but what do you guys think?

 

This has already been explained many times.


The reason there are similarities is because of Ventus joining with Sora in BBS, nothing else.

There is no more speculation to be had about the appearance of those three.

 

I mean I understand what you mean, but it also makes me think what Sora would have grown into if Ventus didn't join with him.
I guess joining with each other's hearts also has physical effects too.

EDIT: Just like the Organization and Xehanort's heart (Xigbar is half Xehanort)

My bad guys I completely missed that thought.

 

What is this 2009? No, they aren't related. Lol.
