Vivillon is a Pokémon with a unique gimmick: it has a distinct visual pattern on its wings determined by where on the planet its game was registered. For each pattern, name at least one valid country that it could be found.
Note that some countries can have multiple patterns and most Vivillon come from multiple countries. Regularly populated overseas territories are also included with their country, but not remote scientific or military outposts.
There are differences between the locations for the 3DS Vivillon patterns and the same locations in Pokémon Go. This quiz will be updated as the latter becomes better defined.
Some countries included are theoretical because Pokémon is banned, unavailable, or not widely played.
Evil aliens have decided to kill everyone on Earth! Fortunately, they've given you two minutes to save as many as you can. All you have to do is name a country to save everyone in it.
