There are plenty of Pokemon that still live in the wild, but yes, there are just as many that have chosen to live in the company of people...

[So yeah, everywhere and anywhere.]

Some people will certainly give them nicknames upon befriending them, while others call them by their species name. I'll admit that I'm the latter, in this particular case.

[Not that he doesn't think his Pokemon aren't deserving of nicknames, just... they've been together for so long that calling them by a different name now would be a little strange.]
