Mass Outbreaks

As you progress through the game, you will start to get warned of Mass Outbreaks happening. These are when swarms of Pokémon go to a specific area of the game. You can have up to one Mass Outbreak in an area at a time.

When you go there, you will see 4 of the same species of Pokémon congregating in an area, but as you defeat them, more will appear until you have defeated or caught all the Pokémon. Each Mass Outbreak will generate between 10 and 15 Pokémon and their stats and shininess are determined when you load the area.

To get a Mass Outbreak, you simply need to return to Jubilfie Village from one of the 5 big areas. When you do, there is a 20% chance of an Outbreak being generated in each of the areas. When you leave Jubilife Village, there's a 20% chance of the area you're not going to despawning the Mass Outbreak.

What is special about Mass Outbreaks is that they have increased shiny chances. Each spawn in a Mass Outbreak has got an added 25 chances of being Shiny, and when you have a Shiny Charm and Perfect Research for that Pokémon, the odds get very good.

Only one Alpha Pokémon can also be spawned by the Mass Outbreak at any one time, so make sure to catch or defeat any that spawn if you wish to get another.

The levels of the Pokémon you encounter in the Space-Time Distortions increases as you progress through the story.
