Vortex Legendary Ribbon

In order to unlock Legendary Pokémon encounters, a player must obtain ribbons by defeating gym leaders. Each ribbon represents a Pokémon region and unlocks its respective legendaries. All gym leaders in a region need to be defeated. You can track your progress from your profile by checking your obtained badges. In the past, elite 4 members, champions, battle frontier brains, and battle maison members had to be completed for all legendary Pokémon to become obtainable but is no longer the case after a v4 update.

Note: Unlike other regions gyms which can be accessed directly via the site navigation under the battle tab, Vortex gyms must be located in the cities of the map. The cities are indicated on the mini-map as red squares.
