The next generation of Pokémon will include over 100 new characters, which will gradually start to show up. When you do so, you'll earn extra candy while you trick or treat with your Buddy Pokemon.
Pikachu himself will be dressed up in a special costume and if your avatar doesn't want to be left out, you can use Mimikyu's Disguise Hat to dress him or her up.
The candy rewards from catching, hatching, and transferring Pokémon will be doubled, and the Pokemon will find candy twice as fast during the Halloween celebration.More news: North Korea turns to Australia for support against Trump in rare letter

Starting from October 20 at 12PM PDT, and running through November 2 at 1PM PDT, players will begin to see new Ghost-type Pokemon like Sableye, Banette when out hunting. Get a look at some of the ghostly Pokemon in the trailer above. You can't tell if a Pokemon is shiny until you enter a match with it, and they're incredibly rare finds!
Players also have the opportunity to stock up for their upcoming adventures with special boxes from the in-game shop featuring items such as Raid Passes and Super Incubators.
Niantic added that more additions to the game will come in December, including new creatures from Pokemon Ruby and Sapphire.
