The first time I played PMD, I got a Charmander then I got to choose my partner, I was thinking along the lines of:
"Hmm.. Cool, I'm a fire-type.. My partner should have an advantage over types that put me in a disadvantage, so Electric and Grass are good against water.. But how about ground and rock types.. I should really choose Treecko... What the heck, i'm going with Pikachu.. A Pikachu tagging along beside me, that'd be epic.. I'd be like Ash, only i'm a Charmander, so I'm like Ashmander or something.."
