Yes.
To get a Shedinja in Pokemon Heart Gold you must trade it from either Pokemon Ruby, Sapphire or Emerald. Jacko25
Impossible. But, you can trade from firered/leafgreen to ruby, or red to gold.
NO! You cannot.
Sadly...NO.
You can't migrate from HeartGold to Ruby. But it can be the opposite. Pokemon can be migrated from Pokemon Ruby to Pokemon HeartGold.
no all Pokemon transfered from GBAs to DS or DSI you have to catch in Pal Park
Either have it as a starter in Pokemon Gold, Silver, Crystal, Soul Silver, or Heart Gold. In Pokemon LeafGreen and FireRed you'll need to trade a Pokemon for it. Also in Pokemon Sapphire, Ruby, and Emerald. In Pokemon Diamond, Pearl, and Platinum you have to trade a Pokemon for it. Hope this helps!
You can get it through a trade from someone who has a Chicorita or Bayleef, or you can trade it from Pokemon Heart Gold or Soul Silver, or Migrate it from Pokemon Ruby, Sapphire or Emerald, but it is only obtainable on those last three games if you trade it from the original Gold or Silver.
No, you cannot
You Can't Find Ho-oh, You Find It In Pokemon Gold, The Only Way To See It In Ruby Is To Stick Gold In A GBA And Trade With Ruby.
You can get Tropius in Heart Gold by the Pokewalker Tree House Routw or trade it from Saphire, Ruby or Emerald. Hop this helps :)
