Diamond/Pearl's rock-type gym leader, Hyouta, has a lot of fangirls already. I'm one of them. ^^
He's a miner, right? And he spends a lot of time in caves? See, I think he should befriend some mawile, which are cave-dwellers. Mah favorite pokemon with mah new favorite gym leader. Or, as GeneChildMewtwo put it more obviously, "Hyouta's cute and mawile's cute."
