How to get Mewtwo in Pokémon: Let's Go
After you defeat the Elite Four in Pokémon: Let’s Go, you’ll likely want to know how to get Mewtwo. Mewtwo can be found hiding out in Cerulean Cave just outside of Cerulean City. If you try and enter Cerulean Cave before beating the Elite Four, a guard standing out front will deny you entry.
It's only after you become the Pokémon League Champion that you're permitted to explore Cerulean Cave in search of rare Pokémon. While there are many Pokémon worth catching, Cerulean Cave houses one of the rarest Pokémon of all… Mewtwo. Need a little help capturing Mewtwo? We’ve got you covered!
Below, we’ve put together a guide on how to get Mewtwo in Pokémon: Let’s Go!
How to Get Mewtwo in Pokémon: Let’s Go
In Pokémon: Let’s Go, Mewtwo can be found inside Cerulean Cave. Until you defeat the Elite Four, you won’t be able to enter Cerulean Cave. As such, you'll want to vanquish the Elite Four and become the new Pokémon League Champion. After that, return to Cerulean City and make your way up the Nugget Bridge.
Next, take a left and use the Secret Technique called Sea Skim to cross the water over to the entrance to Cerulean Cave. Enter the cave, then use Sea Skim all the way until the end of the water channel. Here, you’ll find a single ladder. Take this ladder up, then head North again until you encounter another ladder that leads down to a different floor.
After taking this ladder, head through the next ladder, then enter the chamber where Mewtwo hides. Note that you’ll want to save your game’s progress before interacting with Mewtwo to begin the encounter.

Just keep throwing Foul Play at Mewtwo and he’ll eventually succumb. We were able to best him in around 2 minutes and 30 seconds. After that, you’ll enter the catch phase. Using the Master Ball you obtained by defeating Team Rocket in the Silph Co. building, throw your Master Ball. Accuracy doesn’t matter with the Master Ball, as it’ll open a special animation before capturing Mewtwo.
Once you’ve successfully caught Mewtwo, be sure to save your game right after. Mewtwo is a powerful Pokémon to add to your Party, and looks pretty hilarious when equipped as a buddy Pokémon.
