My life would suck without you
I'd like to evolve Vappy into Vaporeon please :3
I'm going to extend a bit on my answer to the topic. I've used all the evolutions at one point or another. In order of which gets used most, it would probably go Vaporeon, Espeon, Jolteon, Umbreon, Flareon, Leafeon and then Glaceon. Vaporeon is first because it is my favourite obviously and Glaceon is last because of how it's a newer Pokémon and how late it is in the games.
