Because their personalities are different. Roxas has a harder, sharper personality so he has a harder voice. Ven has a soft and caring personality so he has a softer voice
Roxas does not appear in Birth By Sleep. There is Ventus, who looks like Roxas, but is very different than Roxas.
They never recorded this song. Jim Morrison's voice is lower and softer than Eric Burdon's voice.
*NO SPOILERS*Ventus (Ven) is a protagonist in Kingdom Hearts Birth By Sleep, which takes place about 10 years before Roxas came into being, therefore, Roxas and Ven could not be the same person. However, Ventus and Roxas look almost exactly the same with the exception of clothing, which indicates some connection between the two. All of this is explained in Kingdom Hearts Birth By Sleep which is out in Japan and is scheduled to be released on September 7th, 2010 in North America and September 10th, 2010 in Europe. I don't want to ruin the game before it comes out, so lets not spoil the ending.
lOve is sOfter than a petal....
Sort of. Midna is a sort of imp at the beginning of the game, so yes. At the end, when she turns back into herself, her voice is a little calmer and softer than before.
Actually, Axel is a bit older than Roxas, causing Axel to appear much taller.
Namine knows more than Roxas for two reasons. The first, and most obvious, is that Namine (as far as we can tell) has known the Organization longer than Roxas has, giving her more knowledge. The second reason is that Roxas, unlike the rest of Organization, has no recollection of being a person. He has no memory, and barely speaks for the first week. Axel called him a "zombie" to describe Roxas at first.
The object which is softer than petal must be silk.
Riku
Silver is harder than gold but softer than copper.
I believe so, friend.
When someone loses their heart an empty shell is left behind. This shell or vessel then become a nobody, a being that has no heart, thus no true emotions, and is not meant to actually exist. Roxas is Sora's nobody because Sora loses his heart in the first game when he stabs himself with Riku's keyblade to release Kairi's heart. Of course the audience doesn't find out about the existence of Nobodies until Kingdom Hearts 2. In Kingdom hearts 2 when Sora is about to wake up, Diz and Riku get Roxas to reunite with his heart which is Sora. And that's what happens to him. At least that is until you play Birth by Sleep and find out that there is more to Roxas than meets the eye. But that will include me giving out spoilers. If you want to know the connection between Roxas and Ventus from Birth by Sleep ask another question that specifies in that. hope this helps!
