Learn how to defeat Mewtwo in a Pok\u00e9mon GO Raid. These Pok\u00e9mon will be the best to use against this powerful pure Psychic type. The Legendary Pok\u00e9mon, Mewtwo, is finally making an appearance in Pok\u00e9mon GO and will be available as a Tier 5 Exclusive Raid Boss. Mewtwo unlocked at the Yokohama, Japan Pok\u00e9mon GO Stadium event. This guide breaks down what Pok\u00e9mon to use against this dominant Psychic-type Legendary. Mewtwo is a pure Psychic-type Pok\u00e9mon ranking in at number one in attack in Pok\u00e9mon GO. With this being a single type of Pok\u00e9mon, putting a team together may be a little tricky. The Pok\u00e9mon types you want to use to face against Mewtwo are Bug, Dark, and Ghost types. Tyranitar The Dark and Rock-type Pok\u00e9mon is going to be the strongest one you want on your team. While a move set of Bite and Stone Edge is good, you\u2019ll want Bite and Crunch to do the most damage against Mewtwo. Tyranitar will be able to observe a lot of damage with it being partially Dark Type. Houndoom The Dark and Fire-type Pok\u00e9mon will be handy with a move set of Snarl and Foul Play. Houndoom may not be an excellent defensive Pok\u00e9mon but makes up for it with its attack power. Scizor The Bug and Steel evolution of Scyther is undoubtedly one of the most potent Bug-type Pok\u00e9mon to use. A move set of Fury Cutter and X-Scissor will certainly be the best to have. Scizor has excellent defense and an even better attack. Gyarados While this Flying and Water Pok\u00e9mon may be out of its element, it can know Dark-type moves. Similar to Tyranitar, you want a move set of Bite and Crunch to do the most damage. Umbreon The Dark-type evolution of Eevee has a high defense and will surely be one to have if you want to stay in the battle for a long time. You want this Pok\u00e9mon to have a move set of Snarl and Foul Play. Gengar For those looking to get into the fight with a decent hitter, Gengar is going to be the optimal choice. The downside is it's a Poison-type, which is going to get hit by Mewtwo's attacks harder than your other options. However, if you optimize on its attack of Hex and Shadowball, you should well. You'll always want to lean on Dark-type choices, such as Sucker Punch. You may want to throw Gengar in closer to the end of the fight, but you should do well otherwise. These Pok\u00e9mon are the ones you\u2019ll want to have in your lineup when you face this mighty Pok\u00e9mon. If you haven\u2019t been preparing for this fight, I suggest you do so now.
