How to Catch Mewtwo in Any Pokémon Game

What Is Mewtwo?

Mewtwo is a Psychic-type legendary Pokémon featured in the original Pokémon Red, Pokemon Blue and Pokemon Yellow games. Mewtwo is the most powerful Pokémon of the first generation games and was the star of the first Pokémon movie. Mewtwo does not evolve to or from another Pokémon; rather, Mewtwo was cloned from Mew and is a genderless Pokémon. It has a humanoid posture, a long purple tail and three round digits on each finger. Mewtwo has what is suspected to be a secondary spinal cord connecting the skull to the spine.

Mewtwo is decidedly the toughest Pokémon to capture of the first generation games, causing players to hoard their Master Balls for this occasion. Mewtwo is a very strong Pokémon with powerful Psychic-type moves; it’s signature move, Psystrike, has a Power of 100 as well as 100% accuracy. It’s base Special Attack is a whopping 154. Catching Mewtwo is a triumphant moment in any Pokémon game. However, Mewtwo can only be found in a select few of the Pokémon games.

How to Catch Mewtwo

As a Legendary Pokémon, Mewtwo is no easy catch. Legendary Pokémon only appear once in the game and have better stats and movesets than the usual wild Pokémon. If you are serious about successfully capturing the infamous Mewtwo, you’ll need a decent stock of powerful Pokéballs. While it is easiest to snag Mewtwo with a Master Ball, there are other options. Before you start your hunt for Mewtwo, stock up on the following Pokéballs:

  • Master Ball(s)
  • Ultra Balls
  • Timer Balls

The Master Ball is 100% guaranteed to capture any wild Pokémon, no matter the strength or or rarity. In the original Pokémon games, the player only received one Master Ball per saved game; in Pokémon Red, Pokémon Blue and Pokémon Yellow, the player obtains a Master Ball after speaking to the president of Silph Co. after defeating Giovanni. Silph Co. is located in Saffron City in the Kanto region of the Pokémon games. However, in Generation II, Generation III and Generation IV Pokémon games, players are able to win more Master Balls through the Pokémon Lottery Corner and on the Lucky Channel. Both of these lotteries take place on the ground floor of the Goldenrod Radio Tower in Goldenrod City.

Ultra Balls have a 100% higher chance to catch Pokémon than a normal Pokeball and a 33% higher chance than a Great Ball. Most Pokemarts in the Pokémon games sell Ultra Balls for 1200 Pokedollars apiece; while other options are cheaper, Ultra Balls are much more effective and worth the money. If you are going up against Mewtwo and don’t have a Master Ball, try to stock up on fifty or more Ultra Balls—you are going to need them.

Ultra Balls are the strongest Pokeballs you can buy from the Poke Mart.

Timer Balls were introduced in the Generation III Pokemon games as an alternative method to catch wild Pokemon. The starting effectiveness of a Timer Ball is no better than the basic Pokeball; however, for every ten turns that pass in battle with a wild Pokémon, the effectiveness of a Timer Ball increases. Timer Balls are sold for 1000 Pokedollars apiece in most Pokemarts. A Timer Ball’s effectiveness can be calculated with the following formula:

  • Generation III and Generation IV: (Amount of turns in battle + 10) /10 (maximum up to 4x)
  • Generation V: 1x + 1229/4096 (maximum up to 4x)

With all Legendary Pokémon, it is more effective to use Pokémon with certain moves. Legendary Pokémon like Mewtwo are known for breaking out of Pokeballs just when you think you’ve weakened them enough. Carrying Pokémon in your party with moves that cause status ailments can help turn the tides of battle. Some moves to help capture Mewtwo include:

  • False Swipe
  • Spore
  • Thunderwave

False Swipe is a Normal-type move introduced in Generation II games that helps prevent defeating a wild Pokémon by accident. If the player deals more damage with False Swipe than the foe’s current HP, it is guaranteed to leave the target standing with 1 HP. Many Pokemon can learn this move through leveling, such as Cubone or Zangoose. From Generation IV games onward, certain Pokémon can learn the move by purchasing TM54 (such as Sneasel or Gligar). This move is perfect for catching Legendary Pokémon if you can get it.

You can buy TMs like False Swipe from department malls in major cities.

Spore is among the top of the sleep-inducing Pokémon moves out there because it has 100% accuracy; Sleep Powder also puts the target to sleep, but only with 75% accuracy. The accuracy of Hypnosis is a mere 60%. Putting Mewtwo to sleep will help your Pokémon take less damage, give you time to heal your damaged Pokémon and help you do damage to Mewtwo without any counterattacks. Spore can be learned by leveling Paras and Parasect in most games, and is usually learned by level 30.

Paralysis is a Pokémon status ailment that prevents a Pokémon from being able to attack. Under Paralysis, a Pokémon’s speed also decreases by 25%. There are many Pokémon moves that cause Paralysis, many of them being Electric and Ground-type moves. Thunderwave is an Electric-type move with both 100% accuracy and 100% probability of paralysing the target Pokémon. Thunderwave can be learned by many Electric-type Pokémon and is especially effective to have on-hand.

When you leave to catch Mewtwo, keep in mind the level of your party Pokémon, as well as their states and move types. Mewtwo is a level 70 Legendary Pokémon; if your Pokémon are not at least level 65, their moves may not be as powerful or their stats high enough to hold up against Mewtwo. Furthermore, using Pokémon that weak against Mewtwo’s moves or have moves that are weak against Mewtwo won’t get you anywhere. Before you go, make sure that:

  • Your Pokémon’s levels match Mewtwo’s level
  • Mewtwo’s moves aren’t effective against your Pokémon
  • Mewtwo is weak against your Pokémon

Be careful when choosing Pokémon to put in your party; matching Mewtwo’s level is great, but beating it by a longshot could cause you to defeat Mewtwo by accident. While Pokémon level 80 or higher would be much more powerful against a level 70 Mewtwo, their moves might do too much damage (unless you have a Pokemon with False Swipe). Always remember to save your game before approaching Mewtwo, the last thing you want is to defeat the Legendary Pokémon with no way to capture it again.

Mewtwo is immune to no Pokémon type, but resistant to Fighting and Psychic-type moves by 1/2x. These types of moves will cause very little damage to Mewtwo and hinder your abilities. On the other hand, Mewtwo is weak to Pokémon with Bug, Ghost and Dark-type moves. Having Pokémon in your party that fit this description will make damaging Mewtwo easier, and catching the Legendary Pokémon less of a challenge. Be sure to check your own party Pokémon for weaknesses, Mewtwo primarily uses Psychic and Normal-type moves, so avoid Pokémon that are weak to these types.

Where to Catch Mewtwo

Unfortunately, Mewtwo cannot be caught in every Pokémon game that has been made. Players of certain generation games will not be able to obtain Mewtwo without utilizing trading, the Time Capsule, the Pal Park or Poke Transfer. If you own a Pokémon game where Mewtwo is not available, you can play another game that includes Mewtwo, defeat Mewtwo and transfer the Pokémon to your favorite game, or you can try trading over the Nintendo WiFi feature. This article about getting a Charmander in the Pokemon games has more information about these features.

It is only possible to catch Mewtwo in the above Pokémon games. The Red, Blue, Yellow, FireRed, LeafGreen, HeartGold, and SoulSilver games feature the Kanto region of Pokémon, along with Mewtwo’s original location: Cerulean Cave. Up until Pokémon X and Pokémon Y, other Pokémon games that do not involve the Kanto region did not have the ability to capture Mewtwo. Mewtwo is found in the Cerulean Cave (or Unknown Cave), and always available after the player defeats the Elite Four. Beating the Elite Four will give you access to the National Pokedex, after which you can begin to look for Mewtwo.

If you travel to Vermillion City, you will find a cave that is now open. To access the cave, travel north to Route 24 and use the HM03 Surf to get to the cave entrance. Inside the cave, find your way to the bottom floor. At the very bottom of the cave, you will come across Mewtwo. Be aware that wild Pokémon in Cerulean Cave range from levels 46 to 70. If you are looking to avoid wild Pokémon encounters, use a Repel, Super Repel or Max Repel and be sure that the first Pokémon in your team is the highest; wold Pokemon with a lower level than this Pokémon will be avoided.

In Pokémon X and Pokémon Y, players can find Mewtwo in the Unknown Dungeon in Southern Kalos, accessed from Pokémon Village. Using Surf is the only way to reach the small cave! If you are playing Ultra Sun or Ultra Moon, you will find Mewtwo in the Ultra Space Wilds (Rocky World). This is reached through green warp holes. Good luck catching your Legendary Mewtwo!

Jessica Peri (author) from United States on April 05, 2014:

Did you save? I don't know of a way to get a legendary back after defeating it. I'm sorry if that's what happened! If there's a way, I don't know it.

What if accidentally defeated mewtwo?

Jessica Peri (author) from United States on November 19, 2013:

That's true, Dusk Balls are great too. Thanks for the reminder!

PokeMaster on November 17, 2013:

Use a dusk ball. Much more effective . After all. It is in a cave. Just a few tries like 3 is enough but stock up to 15 just in case .
