Armoured Mewtwo from the upcoming new movie Mewtwo Strikes Back: Evolution is making his way to Pokémon GO next week. Serving as a tie-in, his appearence is based on the new look, leaving the classic armour behind.
Armored Mewtwo will appear in five-star raids from July 10 at 1:00 p.m. PDT to July 31 at 1 p.m. PDT
Niantic released a new video for the upcoming raid which shows Mewtwo in action. Other than that, there’s next to no information about the Raid Battle.
