Squirtle was my starter when I played the game, so that has always been a favorite of mine. For some reason I always pick the water Pokemon for my starter in games.

Also, Squirtle was awesome in the show. I mean, look at him! (SPOILER)squirtle_squad_flashback.jpg

Aside from my original Charizard for obvious reasons, my favorite Pokemon card I owned was Umbreon for some reason. It had really awesome art.
