Sora's not childish! He's actually more mature than Riku since he wasn't fooled by the darkness! In anotehr threaad that was exactly lke this, I listed about 16 reasons why Sora's more mature than Riku!
And Sorais more cooler too! Have you seen him in KH2?? He looks AWESOME! But as you guys would say, 'He looks more "mature" and not as "childish"; his expression and the way he moves are also not as "childish".' For the love of God! He never looked immature or acted it and was NEVER childish! Sheesh!
But, for all of you guys who have doubts in there minds, Sora in KH2 is WAY more cooler than Riku! Go look at him again!
And, Sora is ALWAYS cooler than Riku! Even in KH and COM!
There, I made my point.
