Pokemon Scarlet and Violet Mass Outbreaks
Mass Outbreaks are special events that occur randomly throughout your game. They can be found by looking for the ? on your map if you have never encountered the pokemon species before. When approached, a notification will appear telling you that a Mass Outbreak has started and listing which Pokémon is currently spawning in it. You will then have to defeat or capture all of the Pokémon in the area before the Outbreak ends, usually after around 100-120 Pokémon have been defeated.
