I'm turning on my DS for this...
Infernape - Dallas
Empoleon - Shackleton
Torterra - Rio
Alakazam - Salem
Electivire - Windsor
Luxray - Chicago
Manectric - Brisbane
Charizard - Tucson
Ivysaur - Kyoto
Wartortle - Sydney
Swampert - Willowby
Grovyle - Sao Paulo
Combusken - Arlington
I think the trend has become apparent enough. Oh, and this isn't just for these Pokemon, almost every one of them caught in my games is now named after cities or certain geographical regions. I then constantly have a source of unique names that no one else will have.
