Some Pokémon don't wish to evolve. I have three who won't. I think it's a rare thing to happen, but some just want to show their worth as they are. [And can be really stubborn about it, but that's another issue.] There are also Pokémon who just don't evolve at all.

Yeah, Luxio's the second form. They're a great add to the team... then again, all of the Pokémon have something good about them. [Ninetales will come a little closer to warm her trainer more.] Ah-- Thank you, Natsumi...
