The classic king of Pokémon has returned once more. This time, he’s stronger than ever. For a limited time, Armored Mewtwo will appear in Pokémon GO five-star raid battles.

Starting Wednesday, July 10 and going until July 31, Armored Mewtwo will appear in various five star Raid Battles. During this time, players will also be able to purchase a new selection of themed clothing from the Style Shop. Details about the event outside of this are unknown.

Mewtwo alone is a tremendously rare Pokémon. The armored variant will be even more so. The armored form, while having appeared in various Pokémon media productions, is best known for its original appearance in the original Pokémon Movie. The animated film featured a focus on the birth of Mewtwo, who wore an armored coating of technology as he was experimented on in the lab that made him.
