Name of the Rival?

I'm sorry if this belongs in another thread. I couldn't decide but because this doesn't actually have anything to do with the Pokemon I thought here was best.

In diamond and pearl, there is Lucas and Dawn. But what is the other guy's name? I know it is Jun in Japan but what about America?

Barry. I believe that is what its for I have heard it a thousand times and in Japan Jun I think.

I was lame so i named him pawnage xD

According to Bulbapedia, it's Pearl.

Yep. Make of that what you will.

Pearl i think, that's what I named him in my Diamond Game.

He's Damion in some circles. I think. I've heard him reffered to as 'Damion' by a few people.
Who calls a boy Pearl, anyway? He'd be teased horribly if Sinnoh was the real world.
