Vaporeon is my all-time favorite. She's so pretty. My username was originally going to be Vaporeon, but someone already had it.
Coming in second are Dragonair and Weedle. Dragonair is just all around an awesome pokemon. I have always found Weedle absolutely adorable. Gotta love that nose. :3
Favorite Pokemon of the past- Bulbasaur, Shellder, Ditto, Porygon, Togepi, Horsea, Staryu, Starmie, basically any pokemon Misty ever owned, Venonat, Butterfree, Nidorina, Nidoqueen, Nidorino, Nidoking, Vileplume, Hoppip, Wooper, Chinchou. I think that's all.
