Gengar (Mega)

Mega Gengar is a mega raid boss in Pokémon GO. Its best counters are strong Dark types, Psychic types, Ghost types and Ground types such as Mega Houndoom, Darkrai, Mewtwo, Metagross, itself, Chandelure, Giratina-Origin, Groudon, Excadrill, Rhyperior, Garchomp and Landorus.

Gengar can be caught with the following CP values:

  • 1566 – 1644 CP at level 20, no weather boost
  • 1958 – 2055 CP at level 25 with Cloudy or Fog weather boost

Duo shenanigans aside, 3-5 trainers with strong counters should be able to take down Mega Gengar without too much trouble, regardless of weather. The charge move it has in battle should still be kept in mind, however.

  • Since Shadow Pokémon are extremely expensive to power up and require specific events to remove Frustration with a Charge TM, they will NOT be listed as raid counters in this article.

As weird as it sounds, Mega Gengar is its own best counter. Its ridiculously high 349 Attack stat combined with the best Ghost type moveset dishes out damage that is only rivaled by Shadow Mewtwo. However, it should only be used if the raid boss has Focus Blast or Sludge Bomb, since one Shadow Ball would easily KO, even from full health. If the Gengar you wish to mega evolve doesn’t have Lick, Shadow Claw is still very viable. One advantage of using Mega Gengar is it boosts the power of your allies’ Ghost type moves by 40% while it’s in battle, which makes it a fantastic partner for other strong Ghost type attackers such as Chandelure, Giratina-Origin, non-Mega Gengar and Shadow Ball Mewtwo.

Psystrike Mewtwo is here to show that it is the king of Psychic types. It should only be used if the raid boss has Focus Blast though, since Shadow Ball is an easy KO from full health and even Sludge Bomb does huge damage on top of being difficult to dodge. Confusion is slightly stronger than Psycho Cut, but makes it MUCH harder to dodge any of Mega Gengar’s powerful charge moves, which makes it less practical and less useful overall.

Mega Houndoom is the strongest Dark type currently in the game. It also boosts allies’ Dark type moves by 40% while it’s in battle, which makes other strong Dark types such as Darkrai, Weavile, Hydreigon and Tyranitar the ideal Pokémon to use alongside it. Dark types notably are the only Mega Gengar counters that resist Shadow Ball (although it still does a lot of damage, even to bulky ones like Tyranitar) so keep them in mind when building your Mega Gengar Battle Parties.

As previously mentioned, the moveset that Mega Gengar has in the raid battle is usually the biggest factor in deciding what to bring against it, especially if you’re raiding with a few people. Dark types are best used against Shadow Ball since they resist it.

Ghost types double resist Focus Blast and Psychic types (except Metagross) single resist it, making those the ideal options against that charge move. Sludge Bomb is resisted by Ground types, Ghost types, Tyranitar and Metagross, making those the best options against that charge move.

Mega Gengar Duo

Mega Gengar can be duoed, but it can also be difficult as it requires top-tier counters such as itself + Ghost types, Mega Houndoom + Dark types, or Psystrike Mewtwo.

The charge move Mega Gengar has in the raid battle also plays a huge factor in a duo, if not the biggest factor, since it can one hit KO almost all of its counters if it has the right charge move.

The safest way to achieve the duo is to use Psystrike Mewtwo against Focus Blast, or Mega Gengar + Ghost types against Focus Blast. Mega Houndoom + Dark types can also achieve the duo against Shadow Ball, but even a resisted Shadow Ball does a ton of damage due to Mega Gengar’s crazy high Attack stat.

Last but not least, Ground types can duo it against Sludge Bomb, but Sunny weather is mandatory.

Mega Gengar Moveset Analysis

Mega Gengar can have the following moves in a raid battle and when captured as its base form:

Fast Moves Charge Moves
  • Sucker Punch Dark
  • Shadow Claw Ghost
  • Hex Ghost
  • Focus Blast Fighting
  • Sludge Bomb Poison
  • Shadow Ball Ghost

Focus Blast is the easiest charge move overall, since it’s a one bar move and makes Psychic types and Ghost types much better counters. It’s also fairly easy to dodge.

Sludge Bomb is a two bar move that is very difficult to dodge. However, it is resisted by Ghost types, Tyranitar, Metagross and Ground types.

Shadow Ball is a nightmare for everything, even Dark types. Mega Houndoom and Darkrai take more than 50% damage from just one Shadow Ball. Not only that, it’s a two bar move, meaning Mega Gengar will use it frequently in battle.

Sucker Punch is the weakest fast move since it lacks STAB (same type attack bonus), but it is still super effective against Psychic types and Ghost types.

Shadow Claw has STAB, but doesn’t generate energy very quickly.

Hex has one more base power than Shadow Claw and generates energy much faster, making it the deadliest fast move, especially if it’s combined with Sludge Bomb or Shadow Ball.
