What Is The Best Pokemon For Beating Mewtwo?

The best Pokemon to use for this fight is Mew, which you can convenientlyget for free via Mystery Gift if you haven’t already.

Mew willreceive a boost to all of its stats while fighting Mewtwo, and its ability to learn any TM means you can have a lot of coverage.

Any Mew will receive this stat boost, not just the ones received via Mystery Gift.

ItsPsychic typingalso gives itresistance to two out of three of Mewtwo’s attacks.

Grimmsnarlis also a good option for set up, as it can learn several key moves and itsFairy typing means it’s not weak to Aura Sphere.

If you want to try this strategy with another Pokemon,avoid anything weak to Ice, Psychic, or Fighting type moves.Otherwise, Mewtwo will spam a super effective move until your time is up.

What Is The Best Strategy For Beating Mewtwo?

How exactly you go about implementing this strategy willdepend on if you have friends you can coordinate with or not.

If youdo have people to coordinate with, you may eachbuild a Mew specifically to fill a certain role.

If not you’ll have tobuild a jack-of-all-trades Mewand hope whoever you get in random matches knows what to do.

Either waythe key thought behind the strategies is the same.

You’ll want your Mew to have aBug or Ghost tera type. Of the twoBug has better physical moves to use, but Ghost will give you immunity to Aura Sphereinstead of just resistance, so take your pick.

Do not bring a Dark type Mewas its weakness to Aura Sphere meansit’ll get one or two-shot very quickly.

Giveyour Mew max EVs in HP and Attack,as Mewtwo spamming Calm Mind means it’ll undo any Special Defense drops you attempt to use on it. The rest of the points should go toSpecial Defense.

Go witha Jolly naturefor boosted Attack and less Special Attack.

For the battle itself,how you build your Mew from there depends on whether you can coordinatewith people.

Designateone or two people to be the main attackers.

They should have either:

The attacker shouldpick a move to be the main move they’d like to use to attack.For Tera Bug Mews, if you want to spam Leech Life hold a Metronome. If you choose X-Scissor hold a Shell Bell.

Spend thefirst few turns using Snarl or Struggle Bugon Mewtwo. These moveslower its special attack as a bonus, but mainly you want toprepare to Terastalize without wasting PPon your attacking moves.

After thatuse Swords Danceto max out your attack. ThenTerastalize your Mewand startspamming your chosen attack.The other move is mainly there in case you run out of PP.

Set up again when Mewtwo resets your stats.

The remaining players should besupport,and you should haveat least one of each:

If you have aGrimmsnarl,it can run Misty Terrain, Light Screen, Spirit Break and then a free move.

Make sure you haveat least one Mew with Life Dew.

The support players will eachset up either Light Screen or terrain. Then one should use Mud-Slap while the other uses Struggle Bug, Snarl, or Spirit Break.

Mud-Slap lowers Mewtwo’s accuracy, and around three or four should be enough that it’ll start missing attacks often.

The other three moves willdrop Mewtwo’s Special Attack, and should be used continually asMewtwo will keep using Calm Mind.

While you probably won’t be able to minimize its Special Attack with how frequently Mewtwo uses Calm Mind,you’ll prevent it from maxing out its Special Attack and thus one-shotting your team.

As needed,use Life Dew to heal the entire teamor re-set up Light Screen or Terrain.

Set upagain wheneverMewtwo removes negative effectsfrom itself.

The main benefit ofrunning Misty or Electric Terrainis thatit keeps Mewtwo from using Rest to regain its HP.Misty Terrain will also keep you from being frozen by Ice Beam.

With that, you should be all set tohave your attackers whittle Mewtwo down while the support mitigates damage and heals.

If You Are Alone

If you have torely on online matchmaking,this whole process becomes a bit more luck-based, but it is still doable.

You simply have to buildan all-rounder Mew that can do a little bit of everythingand hope the other players have a similar strategy.

You’llwant your Mew to have either:

Spendthe first three to four turns dropping Mewtwo’s statswith Mud-Slap, Struggle Bug, or Snarl.

You’ll only have room for one, sogo with whatever you think is more important,dropping accuracy or dropping Special Attack.

Once you’ve done that, you canset up using Swords Dance.You should be able touse your Teraat this point. Do so anduse your STAB move.

I have never gotten the message that Mewtwo stole some of my Tera Orb’s charge, but I have also had a couple of instances where it took me an unusually long time to activate my Terastalization as thought it had. If that happens just keep spamming your stat dropping move until you can Terastalize.

Set up as needed if Mewtwo resets your stats or its own,while keeping an eye on your health.

The last slot will beMisty or Electric Terrain. This matters less than in the team build becauseyou’re not going to be able to constantly have it up.

When you’re two to three hits away from breaking the shield, set up the terrainto prevent Mewtwo from using Rest.

Mewtwo will only try this once, so you don’t have to worry about keeping it up.

While for other parts of this build you just have to go in and hope one of your allies has the move you didn’t pick.Always have terrain on you if you can’t guarantee someone else will have it.

If you can’t prevent Mewtwo from getting off Rest,you won’t beat it before time runs out.

After thatcontinue debuffing Mewtwo, buffing yourself, then attacking.

If you’re comfortable allowing strangers to do most of the attacking, you can run Mew with Life Dew, Struggle Bug, Misty Terrain, and Mud-Slap andput all your focus on support.

UsePP Ups on moves you’ll be using repeatedlylike your attacking move, Life Dew, Mud-Slap, Struggle Bug, etc. so you don’t risk running out. While it can be a risk to depend on the kindness of strangers, this method has won consistently with random online matches.

If you find that most people while you’re playing are using certain moves but not others,you can also change up Mew’s moveset as needed.
