Who is Mega Gengar in Pokémon Go?

Pokemon 094 Gengar MegaSource: The Pokémon Company

The Mega Evolution of Gen I's Ghost and Poison type, Gengar, Mega Gengar isn't just an incredibly strong Mega Pokémon, but also a big fan favorite. It's easy to see why; just look at him! A mischievous prankster, Gengar hides in the shadows of people and Pokémon alike. It also can fly, possess others, and even absorbs the warmth from its surroundings, literally chilling the air.

Gengar has both a Mega Evolution and a Gigantamax form, though it will be a while yet before Pokémon Go sees any Gigantamax Pokémon. Although Gengar are very rare in the wild because it evolves from Trading, Gengar has been around since day one in Pokémon Go and has been featured in a number of events, including Halloween and even a Community Day, so lots of Trainers will be eager for the change to Mega Evolve their own Gengar.

What are the best counters for Mega Gengar in Pokémon Go?

As a Ghost and Poison type, Mega Gengar is weak to Ground, Ghost, Psychic, and Dark type attacks. It's capable of dealing Ghost, Dark, Poison, and Fighting type damage, making its moveset very important when building counter teams.

Mewtwo

The Legendary Psychic type from Gen I's Kanto region and the top Pokémon in Pokémon Go, Mewtwo will do a ton of damage to Mega Gengar, even if it doesn't last particularly long. As a Psychic type, Mewtwo takes half damage from Fighting, but takes double damage from Ghost and Dark. It also has access to both excellent Psychic moves, Psycho Cut and Psystrike, as well as the most powerful Ghost type move in the game, Shadow Ball. Psystrike is the better of these two moves, but both are invaluable Legacy moves, so don't TM either away! Mewtwo has also been available in a number of ways, including as a Shadow Pokémon, so many players have at least one or two already powered up for this fight.

Mega Gengar

Although Gengar is weak to its own Ghost and Dark type attacks, if you're up against a Mega Gengar with a Fighting or Poison type move, both of which it takes quarter damage from, your Mega Gengar can do a lot of damage before it's knocked out. It will also boost all the other Ghost type counters. If you are bringing a Mega Gengar along, you'll want it to know Lick and Shadow Ball and make sure to coordinate with the rest of your Raid party to get the most out of that Mega boost!

Mega Gyarados

For a Dark type offensive, your best bet is Mega Gyarados. This Dark and Water type Mega Pokémon resists Ghost and Dark type damage, but it takes increased damage from Fighting type moves. It will also provide a hefty boost to other Dark types on the field. You'll want your Mega Gyarados to know Bite and Crunch and be sure to coordinate with your Raid party to get the most out of that Mega boost!

Mega Houndoom

A Dark and Fire type from the Johto region of Gen II, Mega Houndoom is also an excellent choice for this Mega Raid, especially if you can coordinate with the other Trainers. Mega Houndoom takes double damage from Mega Gengar's Fighting type move, but half damage from its Dark and Ghost type moves. It's also one of the easier Mega Raids to beat so coming up with the Mega Energy for it shouldn't be too challenging. If you're bringing Mega Houndoom to this fight, you'll want Snarl and Foul Play for the moveset.

Metagross

A pseudo-Legendary from the Gen III Hoenn region, Metagross is easily the most accessible Pokémon on this list. Having been featured in a number of events, including a Community Day, and even as a Shadow Pokémon, most players have at least a few already powered up. As a Steel and Psychic type, it takes double damage from both Ghost and Dark type attacks, but only a quarter from Mega Gengar's Sludge Bomb. That having been said, the ideal moveset for this Mega Raid is Zen Headbutt and Psychic, whereas Metagross's Community Day exclusive Legacy move Meteor Mash is far more useful overall. So, don't TM for this one!

Giratina Origin Forme

A Legendary Ghost and Dragon type from Gen IV, Giratina makes an excellent counter for Mega Gengar, but specifically the Origin Forme of Giratina. Although Giratina takes double damage from Ghost and Dark type moves, it takes half damage from Poison and quarter damage from Fighting. The Origin Forme hasn't been available as many times as the Altered Forme, but both use the same Candy so many players still have the resources to power up at least one or two. If you're bringing Giratina to this fight, you'll want it to know Shadow Claw and Shadow Ball.

Garchomp

Another pseudo-Legendary, Garchomp is a Dragon and Ground type from the Gen IV Sinnoh region. Its first stage, Gible has been featured in multiple events and hatches from Eggs, so Garchomp is relatively accessible. It has no weaknesses Mega Gengar can exploit and takes half damage from Poison. Mud Shot and Earth Power is the ideal moveset for this Mega Raid. If you don't have the Community Day exclusive move, Earthquake also works here.

Yveltal

Yveltal, the Legendary mascot of Pokémon Y is another great counter for Mega Gengar. As a Dark and Flying type, it resists both Dark and Ghost type damage, and it has no weaknesses Mega Gengar can exploit. Yveltal was the focus of the Luminous Legends Y event and came back during Pokémon Go Fest 2021, so most active players have had the chance to add it to their rosters. Snarl and Dark Pulse are the moves you'll want your Yveltal to know for this Mega Raid.

Darkrai

The Mythical Pokémon Darkrai was originally discovered in the Gen IV Sinnoh region. Although Mythical Pokémon in Pokémon Go are usually limited to one per account, Darkrai was released to Raids like a Legendary Pokémon so most players have had the chance to catch and power it up. While Darkrai may look like a Ghost, it's a pure Dark type, meaning it resists Dark and Ghost type damage, while taking increased damage from Fighting type moves. If you're bringing Darkrai to this fight, Snarl if the fast move you'll want and Dark Pulse is the charged move.

Mega Slowbro

Although its individual performance is lacking, Mega Slowbro is currently the only Psychic type Mega Pokémon in Go. If you're planning a Psychic based offensive and need a little extra boost, Mega Slowbro will do that in its short moments on the field. As a Psychic and Water type, its going to take increased damage from Mega Gengar's Ghost and Dark type attacks, while resisting its Fighting type move. Confusuion and Psychic are the ideal moveset for this fight.

Landorus (Therian forme)

Although it has an inferior moveset, Therian forme Landorus still outperforms Incarnate forme in this Mega Raid. As a Ground and Flying type, Landorus resists Fighting and Poison type moves, while having no relevant weaknesses. Unfortunately, the Therian forme has seen less Raid time than the Incarnate forme, but both use the same Candy, so you may already have the resources to power it up. Extrasensory and Earthquake are the ideal moves for a Therian forme Landorus in this Raid.

Latios

Pokemon 381 LatiosSource: The Pokémon Company

A Legendary from the Hoenn region of Gen III, Latios is our last top counter for Mega Gengar. As a Psychic and Dragon type, it takes increased damage from Ghost and Dark, but resists Fighting type. Latios has also been available many, many times in a number of different ways, so most players have had several opportunities to add it to their roster. If you're bringing Latios to this Mega Raid, you'll want Zen Headbutt and Psychic for its moves.

Back ups?

Although most players will be able to make a team of the best counters, if you're finding a gap in your team, there are plenty of back ups who work well in larger groups. Just make sure you're dodging and any of the following could be a decent back up:

  • Landorus (Incarnate forme) with Mud Shot and Earth Power
  • Groudon with Mud Shot and Earthquake
  • Latias with Zen Headbutt and Psychic
  • Victini with Confusion and Psychic
  • Jirachi with Confusion and Psychic
  • Excadrill with Mud-Slap and Drill Run

  • Rhyperior with Mud-Slap and Earthquake
  • Krookodile with Snarl and Earthquake
  • Rhydon with Mud-Slap and Earthquake
  • Bisharp with Snarl and Dark Pulse
  • Honchkrow with Snarl and Dark Pulse

Shadow Pokémon?

The rebalance of Shadow Pokémon rescued from Team GO Rocket make them excellent glass cannons. Not only are their stats boosted, but during special events or with Elite TMs, it's possible to change their moves. If you happen to have any of the following Pokémon with the right moveset, they will work very well in this Raid:

  • Shadow Mewtwo with Confusion and Psystrike
  • Shadow Tyranitar with Bite and Crunch
  • Shadow Weavile with Snarl and Foul Play
  • Shadow Metagross with Zen Headbutt and Psychic
  • Shadow Gallade with Confusion and Psychic
  • Shadow Alakazam with Confusion and Psychic
  • Shadow Houndoom with Snarl and Foul Play
  • Shadow Honchkrow with Snarl and Psychic
  • Shadow Mamoswine with Mud-Slap and Bulldoze
  • Shadow Raikou with Thunder Shock and Shadow Ball

Note: Shadow Mewtwo outperforms all of the best counters despite having weaknesses Mega Gengar can exploit.

How many players does it take to beat Mega Gengar in Pokémon Go?
