Dissidia Voice: ...Too Childish?

[Lavos]

I had just gotten the Dissidia demo for the PSP, and when fighting Zidane and hearing his voice for the first time, I though it was a little too childish. I got over it after remembering that he was 16, but still. It could have just been in the battle, and sounds different in cut scenes, like Sora in KH2, but I don't know.
