3rd Gen The sun and the moon.

I've never used any of those in battle before, but Lunatone because of it's nose XD looks like a duck. I have to say, Solrock looks pretty cool in HG/SS, cuz you just have this sun thing bobbing up and down behind you.

Lunatone! Definitely. I was always jealous of my cousin because he could get Lunatone and I couldn't. I knew I should've gotten Sapphire first!
