Who is Mewtwo in Pokémon Go?

One of the strongest and most recognizable Legendary Pokémon, Mewtwo is one of a select few artificial Pokémon, created intentionally by humans. The scientists who created Mewtwo spent many years conducting horrific experiments, splicing and cloning DNA from Mew, the common ancestor of virtually all other Pokémon. Because Mew has the DNA of virtually all other Pokémon, it can learn every move in the core game. Mewtwo came very close, but due to the horrific experiments conducted on it, Mewtwo is believed to be the most savage of Pokémon, harboring deep seated hatred of humanity. Mewtwo is also one of only two Pokémon with multiple Mega Evolutions. Neither Mega Mewtwo X or Mega Mewtwo Y have been intoduced to Pokémon Go... yet.

In Pokémon Go, neither Mewtwo nor Mew can learn every move, but they can learn a very wide range of moves. Mewtwo's diverse movepool and excellent stats make it one of the most powerful Pokémon in all of Pokémon Go. It's Shadow forme is the strongest Pokémon in the game by far. Whether you're looking to add another Mewtwo to your roster or to power up your existing Mewtwo, this is a Raid you won't want to miss out on!

What are the best counters?

As a pure Psychic type, Mewtwo takes double damage from Bug, Ghost, and Dark types. What makes Mewtwo most threatening though (aside from killer stats) is its wide range of moves. In this Raid, Mewtwo has the potential to deal Psychic, Fighting, Electric, Fire, and Ice type damage.

Mega Gengar

Even outperforming Shadow Mewtwo, Mega Gengar should be your first choice for this Raid. A Ghost and Poison type, Mega Gengar is going to take double damage from Mewtwo's fast attack, as well as any Psychic charged attack. If Mewtwo had Focus Blast, Mega Gengar takes reduced damage from Fighting. Even taking double damage from Psychic moves, Mega Gengar still outperforms every other Pokémon in this Raid, so if it's possible to bring one, you absolutely should. Shadow Claw and Shadow Ball are the moves you'll want your Gengar to know.

Mega Houndoom

If you're lacking in Mega Gengar Energy or already have a Mega Houndoom ready, Mega Houndoom performs incredibly well in this Raid. The Mega Evolution of Gen II's Houndoom, this Fire and Dark type resists Psychic, Fire, and Ice, while taking double damage from Fighting. Even with all that resistance on its side, it's still not quite as durable as Mega Gengar, but if you can coordinate with your fellow Raiders, Mega Houndoom makes a great lead for a Dark based counter team. If you're bringing Houndoom to this fight, you'll want it to know Snarl and Foul Play.

Mega Gyarados

Another Mega Pokémon to add to the list, Mega Gyarados doesn't perform quite as well as Mega Houndoom in this Raid, but if you've got the Mega Energy to spare, it will still serve you well. As a Dark and Water type, Mega Gyarados resists Psychic, Fire, and Ice type damage, but takes increased damage from Electric and Fighting. It will also boost the other Dark types on the field so coordinate with your fellow Raid party if it is safe to do so. Bite and Crunch are the moves you'll want your Mega Gyarados to know for this fight.

Origin Forme Giratina

The Legendary mascot of Pokémon Platinum, Giratina performs well against Mewtwo, but specifically in its Origin forme. Because Giratina is a Ghost and Dragon type, Ice Beam is the only move Mewtwo could potentially have that would deal super effective damage, and Giratina takes reduced damage from Fighting, Fire, and Electric. If you're bringing Giratina to this Raid, you'll want Shadow Claw for its fast move and Shadow Ball, which Altered forme Giratina doesn't have access to, for its charged move. Unfortunately, Origin forme Giratina hasn't been available as often as the Altered forme, but if you have it, it will make a great addition to your team.

Chandelure

Originally encounted in the Unova region of Gen V, Chandelure is a great counter for Mewtwo. One of the best Ghost and Fire types in the game, it resists Ice, Fire, and Fighting type moves, and it has no weaknesses this Mewtwo can exploit. Even better, its first stage, Litwick has been featured in multiple events, including both 2019 and 2020's Halloween events, and can even be hatched from Eggs right now. Just make sure your Chandelure knows its Ghost type moves Hex and Shadow Ball, as opposed to its Fire type moves.

Darkrai

A Mythical Pokémon originally encountered in the Sinnoh region, Darkrai may look like a Ghost, but it's actually a pure Dark type. This means it's super resistant to Psychic type moves and the only move you'll have to worry about is Focus Blast. Although it is a Mythical type, Darkrai has had widespread availability, with several runs in Raids and even being a Pokémon Go Battle League reward encounter, so you probably already have at least one powered up. Snarl and Dark Pulse are the ideal moves for Darkrai.

Yveltal

The Legendary mascot of Pokémon Y, Yveltal performs great against Mewtwo, especially when paired with Mega Houndoom or Mega Gyarados. This Dark and Flying type will take super effective damage from Mewtwo's Electric and Ice type attacks, but resists Psychic type damage and it's quite the tank. Although Yveltal has only had one run in Raids so far, it was recent so most active players already have at least one or two ready for this Raid. Snarl and Dark Pulse are the moves you'll want your Yveltal to know going up against Mewtwo.

Mewtwo

Ironically enough, Mewtwo can be a great counter for itself, thanks to the Legacy move Shadow Ball. While the Mewtwo you're fighting in Raids now won't have access to this incredible Ghost type move, you may already have one that has this move or an Elite TM to get it. Mewtwo takes reduced damage from Psychic type moves and brings no relevant weaknesses to this fight, meaning it's also super sturdy. If you are bringing Mewtwo to this Raid, pair Psycho Cut and Shadow Ball to deal the maximum damage. However, if your Mewtwo doesn't know Shadow Ball, best to leave it at home, and if your Mewtwo knows Psystrike, don't TM this move away. Psystrike is also a Legacy move and Mewtwo's best Psychic attack.

Weavile

Originally discovered in the Sinnoh region of Gen IV, Weavile is a great counter for Mewtwo that's also readily accessible. It's first stage, Sneasal is a common Gen II Pokémon that has also been featured in events and as a Shadow Pokémon, so you probably already have a couple in your collection. As a Dark and Ice type, Weavile takes reduced damage from Ice and Psychic, but double damage from Fire and quad damage from Fighting. If you're bringing Weavile to this fight, you'll want it to know Snarl and Foul Play.

Hydreigon

A pseudo-Legendary originally encountered in the Unova region of Gen V, Hydreigon performs well in this Raid. As a Dark and Dragon type, it takes reduced damage from Psychic, Fire, and Electric, but double from Fighting and Ice. However, despite its first stage, Deino, being featured in events, Eggs, and even as a Pokémon Go Battle League reward encounter, Deino are still quite rare, so many players don't have the Candy to power up their Hydreigon. Still, if you have one, you'll want Bite and Dark Pulse for the moveset.

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:

  • Gengar with Shadow Claw and Shadow Ball
  • Tyranitar with Bite and Crunch
  • Mega Beedrill with Bug Bit and X-Scissor
  • Genesect with Fury Cutter and X-Scissor
  • Mega Blastoise with Bite and Hydro Cannon
  • Banette with Shadow Claw and Shadow Ball
  • Houndoom with Snarl and Foul Play
  • Absol with Snarl and Dark Pulse
  • Pinsir with Bug Bite and X-Scissor
  • Bisharp with Snarl and Dark Pulse
  • Mismagius with Hex and Shadow Ball
  • Reshiram with Fire Fang and Crunch
  • Krookodile with Snarl and Crunch
  • Raikou with Thunder Shock and Shadow Ball
  • Zekrom with Dragon Breath and Crunch
  • Mega Manectric with Snarl and Wild Charge
  • Escalavier with Bug Bite and Mega Horn

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 Psycho Cut and Shadow Ball
  • Shadow Weavile with Snarl and Foul Play
  • Shadow Tyranitar with Bite and Crunch
  • Shadow Houndoom with Snarl and Foul Play
  • Shadow Absol with Snarl and Dark Pulse
  • Shadow Pinsir with Bug Bite and X-Scissor
  • Shadow Raikou with Thunder Shock and Shadow Ball
  • Shadow Mismagius with Hex and Shadow Ball
  • Shadow Alakazam with Psycho Cut and Shadow Ball
  • Shadow Banette with Shadow Claw and Shadow Ball
  • Shadow Sharpedo with Bite and Crunch
  • Shadow Gardevoir with Charge Beam and Shadow Ball

Note: Shadow Mewtwo, Shadow Weavile, and Shadow Tyranitar outperform every non-Mega Pokémon in the best counters list. Shadow Houndoom, Shadow Pinsir, Shadow Absol, Shadow Raikou, Shadow Mismagius, and Shadow Alakazam also perform on par with the other best counters. If you can safely coordinate the use of Mega Gengar, Mega Houndoom, or Mega Beedrill, they will boost Ghost, Dark, and Bug types respectively, making those type Pokémon perform even better.

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

While it is possible for three high level Trainers to take out Mewtwo under ideal conditions with the best counters, this is not an easy Raid and Mewtwo's moveset could make it much more difficult. Personally, I'll be aiming for parties of five Trainers or more.

Weather conditions that can impact this Raid include:

  • Wind will boost Mewtwo's Psychic type moves.
  • Cloudy Weather will boost Mewtwo's Fighting type move.
  • Sunny/Clear Weather will boost Mewtwo's Fire type move.
  • Rain will boost Mewtwo's Electric type move and your Bug type counters.
  • Snow will boost Mewtwo's Ice type move.
  • Fog will boost both your Ghost and your Dark type counters.
