This guide covers everything you need to know about Mewtwo in Pokémon Stadium, including how to unlock the secret Mewtwo fight, obtain the Mythical Pokémon Mew, and challenge yourself in ‘R-2‘ mode.

Can You Play as Mewtwo in Pokémon Stadium?

The only way to use Mewtwo in Pokémon Stadium is to connect Pokémon Red, Blue, or Yellow via the Transfer Pak and use one you caught in-game.

As the Nintendo Switch Online version of Pokémon Stadium has no Game Boy connectivity, Mewtwo cannot be used in this version of the game.

You can, however, unlock a secret bonus mode in which you can fight Mewtwo in a six-VS-one battle. Beating Mewtwo will unlock the Mythical Pokémon Mew and the tough-as-nails Round-2 mode, which increases the difficulty of Stadium tournaments and Gym Leader Castle.

Best Team to Beat Mewtwo VS in Pokémon Stadium

The best team to fight Mewtwo in Pokémon Stadium is:

• Electrode
• Persian
• Rhydon
• Onix
• Exeggcute
• Any sixth Pokémon

How to Beat Mewtwo

Send out Electrode and use Thunderwave to paralyze Mewtwo. Use Thunder the following turn and repeat until Electrode faints.

Next, send out Persian and use Screech to lower Mewtwo’s defense. If both Screeches were successful and Mewtwo is still paralyzed, you can use Hyper Beam to faint it.

If this fails, send out Rhydon to replace Persian and use Earthquake until Mewtwo faints. If you’re unlucky with your initial Screech attempts, you may need to use Onix and Exeggcute‘s Self-Destruct to finish it off.
