If you’ve dreamed of taking on a Raid Boss with a Mega Gengar in your party, your days of pining will soon be over! To celebrate the spookiest holiday of the year, the Shadow Pokémon’s Mega Evolution will be featured in Mega Raids starting October 23, 2020, at 6:00 p.m. PDT, replacing Mega Venusaur. Since Gengar is a Ghost- and Poison-type Pokémon, teams with Pokémon that know Ground-, Psychic-, Ghost-, or Dark-type attacks will be particularly effective, so you may want to plan accordingly.
Mega Gengar raids will be just a few of the many Halloween-themed activities taking place in Pokémon GO’s Halloween celebration this year, so be sure to check out everything the spooky season has in store.
