Pokémon GO Mega Gengar Guide: Best Counters, Attacks & Pokémon to Defeat It
Mega Gengar is a Pokémon that appears in Mega Raids in Pokémon GO, and in this guide you’ll find the best counters for it.

Ghost, Psychic, Ground, and Dark-type Pokémon with powerful attacks of the same type are the most effective against Mega Gengar, meaning the use of Mega Evolutions or Dark Pokémon is even better. For those that don’t have those types, using the strongest Pokémon available with good DPS and STAB is the best bet.

In order to have a higher chance of success, it’s advised to take on the Mega Raid with a group of at least five people rather than solo. Here is a selection of Pokémon to use against Mega Gengar in Pokémon GO: Mewtwo with Confusion (Fast Attack) and Mind Wave (Charged Attack), Hoopa (Unleashed) with Confusion (Fast Attack) and Psychic (Charged Attack), Giratina (Origin Forme) with Shadow Claw (Fast Attack) and Shadow Strike (Charged Attack), Latios with Zen Headbutt ( Fast Attack) and Psychic (Charged Attack), Landorus (Totem Form) with Mud Shot (Fast Attack) and Earthquake (Charged Attack), Hydreigon with Bite (Fast Attack) and Fel Spin (Charged Attack), Mega Latios with Zen Headbutt ( Fast Attack) and Psychic (Charged Attack), Mega Alakazam with Confusion (Fast Attack) and Psychic (Charged Attack), Mega Latias with Zen Headbutt (Fast Attack) and Psychic (Charged Attack), Dark Mewtwo with Confusion (Fast Attack) and Mind Wave (Charged Attack), Metagross Oscuro with Zen Headbutt (Quick Attack) and Psychic (Charged Attack), Dark Latios with Zen Headbutt (Quick Attack) and Psychic (Charged Attack).
