I have a couple of Pokémon that refused to evolve. They don't even need stones. My Cubone and Charmander are past their evolution levels and they aren't budging. I've never heard of a Pokémon avoiding a stone, though.

I guess I should start working on my team sometime. I'm never too concerned with types.

Talk in your head? What the hell... that's crazy! Not Pokémon-talk crap or anything, but stuff you can actually understand?
