I am level 15, I'm Team Valor, and I have caught 71 different Kanto pokemon and seen 72 of them.I've caught Bulbasaur, Charmander, Squirtle, Caterpie, Metapod, Butterfree, Weedle, Kakuna, Beedrill, Pidgey, Pidgeotto, Pidgeot, Rattata, Raticate, Spearow, Fearow, Ekans, Pikachu, Sandshrew, Nidoran(both male and female), Nidorina, Nidorino, Nidoking, Clefairy, Clefable, Vulpix, Jigglypuff, Zubat, Golbat, Oddish, Gloom, Paras, Venonat, Venomoth, Meowth, Psyduck, Golduck, Mankey, Growlithe, Polywag, Abra, Kadabra, Bellsprout, Weepinbell, Tentacool, Geodude, Slowpoke, Seal, Shellder, Cloyster, Gastly, Haunter, Drowzee, Krabby, Exeggcute, Exeggutor, Cubone, Hitmonlee, Rhyhorn, Tangela, Horsea, Goldeen, Staryu, Tauros, Magikarp, Eevee, Vaporeon, Jolteon, Flareon, and Dragonite.I've found, but didn't catch, Marowak.
I haven't enjoyed Pokemon since middle school, but man do I find this game addicting. I've created a route on my way home from work where I can hit up to 6 poke stops and my wife and I go to a nearby Penn State campus where they have well over 10 stops, 4 gyms, and a pond that's great for catching water pokemon. I can't wait for trading to become an option and I'm hoping I can catch around 100 of the Kanto pokemon before they implement a new region.
My best 6 pokemon are:
Dragonite: 1571 CP
Exeggutor: 1177 CP
Vaporeon: 1010 CP
Jolteon: 836 CP
Clefable: 826 CP
Flareon: 824 CP
