But finding Mega Stones in Pokemon Let’s GO isn’t always easy because the game doesn’t give you explicit instructions for most of them. Fortunately, we’ve got you covered with this handy guide.

What is Mega Evolution?

If this is your first foray into Pokemon, you might be wondering what the heck Mega Evolution is to begin with. Put simply, it’s a temporary evolution using a Mega Stone, transforming a specific Pokemon into a mega-powerful version of itself.

Not all Pokemon can do this, as not every Pokemon has its own Mega Stone, and the effects last only until the end of the battle. But it’s a nice way to turn the tide of battle if it should be going against you. Plus it just looks cool.

In previous games, a Pokemon would have to hold its Mega Stone, but since the hold feature wasn’t present in Gen I, you just need to have the Stone in your possession and choose to Mega Evolve as one of your options in battle.

Mega Stone List

You’ll receive some Mega Stones as you progress in the game, specifically the ones for the three Kanto starters and both of Mewtwo’s Mega Stones

Starter Mega Stone Locations

Venasaurite: receive from Blue in Prof. Oak’s Lab after you earn the Volcano Badge from Cinnabar Gym Charizardite X and Charizardite Y: receive from Blue in Prof. Oak’s Lab after you earn the Volcano Badge from Cinnabar Gym Blastoisenite: receive from Blue in Prof. Oak’s Lab after you earn the Volcano Badge from Cinnabar Gym

In most cases, Mega Evolution won’t change a Pokemon’s types. However, Charizard’s Mega forms are a bit different. Charizardite X turns it into a Fire/Dragon type, though Charizardite Y keeps it as the usual Fire/Flying.

Mewtwo’s Mega Stones Location

Mewtwonite X and Mewtwonite Y: after defeating Green, check the spot where you found Mewtwo.

Mewtwo gets a few changes with its Mega forms as well. Mega Mewtwo X is a Psychic/Fighting hybrid. It gets a massive boost in its Attack stat while retaining its normally terrifying Special Attack as well, making it pretty close to the ultimate Pokemon.

Mega Mewtwo Y is a normal Psychic type, inverting Mewtwo X’s stats –incredibly high Special Attack, comparable Attack stat. It might not be as multi-purpose as Mewtwo X, but it’s still worth your while.

Other Mega Stones

There are nine other Mega Stones you can acquire in Pokemon Let’s GO, but they all actually come from the same place.

After you become the Champion, there’ll be a man dressed as a Poke-Maniac (the ones in the Slowpoke costumes), and he sells you these other stones for 30,000 PokeDollars each.

Mega Evolution might not be as robust as in Gen VI, but it still offers some variation on the usual Gen I experience.
