Tips on how to Capture Mewtwo in Pokemon FireRed and LeafGreen
Once your Pokemon team is prepared and supplies prepared, face Mewtwo in its lair in Cerulean Cave B2F. To catch Mewtwo successfully in Pokemon FireRed and LeafGreen, follow these steps rigorously:
- Save your game before facing Mewtwo.
- Reduce the HP levels of Mewtwo to red.
- Use Status moves or effects to hinder Mewtwo.
- Throw the Ultra Balls at Mewtwo to capture it.
Mewtwo could be caught early in the primary turn using a Master Ball, especially whether it is Shiny Mewtwo. Nevertheless, if players desire a challenge or want to save lots of the Master Ball for an additional legendary Pokemon, proceed reading our guide below:
Save Your Game Before Facing Mewtwo
As mentioned before, players should save their progress before engaging Mewtwo. Saving before the Super boss encounter allows players to repair mistakes in team construct, execution, missing items, or having a Pokemon faint.
Lower the HP of Mewtwo to Red
Begin the battle with Scyther or Scizor’s Fury Cutter or Tyranitar’s Crunch moves to deal STAB (Same Type Attack Bonus) damage to Mewtwo. Then, switch to Hunter, Gengar, Misdreavus, or Sneasel to deliver chip damage on the Genetic Pokemon.
If Mewtwo uses its Get well move, players can switch back to Scyther, Scizor, or Tyranitar to do massive damage while not fainting the legendary Pokemon.
Use Status Moves to Hinder Mewtwo
Switch to Hunter, Gengar, Misdreavus, Sneasel, or Parasect to inflict Mewtwo with a Status Condition. To impair the Legendary Pokemon, use Status moves like Sludge Bomb for Poison, Confuse Ray for Confusion, Stun Spore for Paralysis, or Spore for Sleep. Mewtwo can only have one negative status at a time, and having it makes it easier to capture during battle.
If Mewtwo uses its Safeguard move, turn back to dealing damage without flattening the Genetic Pokemon. Safeguard’s effect lasts five turns.
Throw Ultra Balls at Mewtwo until it’s Captured
Catch Mewtwo successfully with a Master Ball. If players are reserving it for other legendary Pokemon, they will utilize Ultra Balls as an alternative.
The Master Ball is earned by rescuing the president of Silph Co. and beating Giovanni in Saffron City. Meanwhile, Ultra Balls could be obtained through pick-up in various Kanto areas or by purchase at Poke Mart branches in Fuchsia City, Cinnabar Island, Indigo Plateau, and Sevii Islands.
Tips on how to Hunt Shiny Mewtwo in Pokemon FireRed and LeafGreen
Mewtwo, like other legendary Pokemon, is just not Shiny locked. To come across the green-colored variation of the Genetic Pokemon, rigorously follow these instructions:
- Save your progress at Mewtwo’s lair at Cerulean Cave B2F.
- Start the battle with Mewtwo to see whether it is shiny or not.
- If not, do a Soft Reset by pressing A, B, X, and Y concurrently to return to the title screen.
- Reload your saved file and try to capture Shiny Mewtwo again.
Because the Shiny Charm is just not yet implemented in Generation 3, players can only acquire Shiny Mewtwo by probability in battle.
