The annual "Pokémon GO Halloween" event has begun. This year, with the introduction of Mega Evolution, the long-awaited Mega Gengar makes its first appearance.

For a limited time only, Gengar wearing a costume inspired by Mega Banette will appear as a raid boss, while Sableye wearing Litwick style hats will appear in the wild and hatch from eggs.

In addition, there are many other Pokémon you want to secure, such as the first appearance of Galarian Yamask and the evolved Runerigus, and the first appearance of Spiritomb since last year's Special Research (the shiny one is the first appearance).

The legendary raid boss is Darkrai, and the bonus is double the candy on the capture, and double the candy sent to the doctor. There's also exclusive special research, time challenges, field research, and a new event during the period, Catch Mastery: Ghost Day, GO Battle League: Halloween Cup, Alolan Marowak Raid Day, and a whole lot of other things to do on Halloween.
