    Go to Island 1. You will need a Pokémon who knows Surf to do this. Speak to Celio and he will explain that you need to find an item for his machine.

  2. 2

    Go to the entrance of Mt. Ember. On the lower right side of the area, you will see some Team Rocket members. You will hear the first password to the Rocket Warehouse. Battle them, and enter the cave.

  3. 3

    Proceed all the way down to the bottom level. You do not need to read any of the braille charts. You will need a Pokémon with Strength to get through the cave.

  4. 4

    Pick up the Ruby and exit. You can either use an escape rope, use "Dig" or exit the way you came in.

  1. 1

    Go to Island 6 and find the Dotted Hole, which can be seen on the Town Map. At the entrance, read the braille sign. It will say "Cut," so you make sure you bring a Pokémon who knows Cut.

    • If you have not yet saved Lorelei from Island 4, a scientist will be blocking the way.

  2. 2

    Inside the cave, look at the braille signs. They will tell you which hole to fall down. If it has 2 symbols, it means go up. If it has 5, then it's right. If it has 4, then it is either left or down. If you mess up, you will have to start over again.

  3. 3

    On the bottom level, you will see the Sapphire. Don't get too excited; a super nerd will take it first. He will then give you the second password for the Rocket Warehouse.

  4. 4

    Go to the Rocket Warehouse, found on Island 5. You will need to defeat all the Team Rocket members to get to the boss.

  5. 5

    In the final room, you will find the super nerd who stole the Sapphire. Battle him. When you beat him, you will get the Sapphire.

  6. 6

    Travel to Island 1. Give the gems to Celio, the man who operates the machine on the island. He will connect the regions of Kanto and Hoenn by signal and open up the way to Mewtwo.

  3. 3

    At the end, you will see Mewtwo. Save your game before battling him, as this is your only chance to catch him and he is very powerful. See the Tips section for some methods of catching Mewtwo. You should bring at least 50 Ultra Balls.

    How to Catch Mewtwo in Pokémon FireRed and LeafGreen (23)

    Eric Mylonas, Gaming Strategy Expert

    When facing the genetically engineered Pokémon Mewtwo, preparation is key. Come equipped with plenty of Ultra Balls and healing items to withstand its devastating psychic attacks. Lower its HP significantly while inflicting status conditions like paralysis or sleep to stop it from recovering. Even for experienced trainers, catching this powerful legendary will require skill, strategy, and a bit of luck.

      Tips

      • Inflict some status effect on Mewtwo. Freeze and sleep work the best, but others like paralysis can work as well.

        Thanks

      • If you want to save your Master Ball, stock up on Ultra Balls (around 70). Timer Balls can also be effective, for their success rate increases the longer the battle goes on. Mewtwo can be caught with these, but it is very difficult.

        Thanks

        Helpful1Not Helpful1

      • Save prior to the battle and restart until you succeed.

      • You can get easily disoriented in the Cerulean Cave; consult a map if you need help navigating.

      • Max Repels do work on the Pokémon in the cave. However, if your active Pokémon is a lower level than the wild Pokémon, the Repel won't work. For best effect, put your strongest Pokémon in the active slot.

Then, make your way to the Rocket Warehouse on Island 5, battle all members of Team Rocket, and retrieve the sapphire from the super nerd. After you’ve gotten the sapphire, travel to Island 1 and give both of your gems to Celio, who will open the way for you to get to Mewtwo.
