I recently dumped my PC into the Pokémon Bank, started a new game, and moved all my pokémon back. Now that I'm about two-thirds of the way through my new game, I was browsing my pokédex and noticed something curious. Most of the pokémon registered as "caught" have the usual tricolor pentagon symbol next to them, but a few have a regular pokéball design. The latter group seems to be comprised mostly of pokémon I transferred from a GenV game, but my articuno was acquired through the GTS. Does this mean that whoever gave me the articuno through the GTS acquired it through a previous game or is my assumption off completely?
