I would love to get my hands on one of those charmanders if at all possible, I don't have much to over except some legendarys that I plucked out of the guy who owned my copy before me's save file. I can give you one of the following for a charmander if you are interested. Kyurem, Thundurus, Cobalion, Zekrom, and Terrakion.
I'm from Belgium, my game is in English so I'm not sure if you'll get a shiny from it. I do have a Lv.59 trained Japanese Zoroark that used to have Pokerus if you're interested. I can also get you another pokemon with Pokerus if you want
