Hello, I want a Charmander but I don't know how to get one other then the Luminous one in the games corner and when you're selecting your starter. Is there a way for me to get a Charmander?

And if anybody is willing to trade a level 5 Charmander, I will gladly take it. I need it for my gym battle in Johto Region. -sigh-

You can get other colors of Charmnader besides Luminous and normal. :L I don't think there's another way to get a normal one other than from someone who owns one, and the colored Charmanders you can get from other players as well. And like you said, Luminous ones can be obtained in the Game Corner.
