So I'm playing Pokemon Black 2 and I want to capture Regigigas. However, I don't want to use White 2 version to transfer over Regice as I do not own that game. If I were to transfer up all three Regis from Ruby, Sapphire, or Emerald, would they be able to wake up Regigigas in B2 version? I've seen this asked on different websites a few times but I've never seen any straight answers. Thank you!
