When can you catch Armored Mewtwo in Pokémon GO?
Armored Mewtwo will appear in five-star raids during Pokémon GO Fest 2026: Mega Finale. According to reports, raids begin at 10 a.m. on Saturday, September 5 and run until 6 p.m. on Sunday, September 6, all in trainer local time.
That narrow window makes this one of the most time-sensitive raid opportunities of the year. OpenCritic notes there is no guarantee Armored Mewtwo will return again soon, so players who missed its original 2020 run may want to prioritize the weekend.
Why is Armored Mewtwo special in Pokémon GO?
Armored Mewtwo is based on the version seen in the 2019 film Pokémon: Mewtwo Strikes Back – Evolution. Scopely describes it as a form whose power is suppressed and held back by armor, yet still strong enough to surpass most other Pokémon in raid battles.
This marks the first time Armored Mewtwo has been obtainable in Pokémon GO since its original limited release roughly six years ago. For collectors and raid-focused players, that long gap is a big part of why the Mega Finale announcement landed with such force at Worlds.
What else is happening at Pokémon GO Fest: Mega Finale?
The event is not only about Armored Mewtwo. Mega Mewtwo X will headline Mega Raids on Saturday, September 5, while Mega Mewtwo Y takes over on Sunday, September 6, according to Pokémon GO Hub.
Mega Mewtwo X gains Dynamic Punch+, which boosts damage against Mega-Evolved raid bosses and can break two shields at once in Super Mega Raids. Mega Mewtwo Y unlocks Future Sight+, revealing Pokémon that will appraise as three-star or higher during encounters.
Eleven other Mega Pokémon are also receiving new Charged Attacks during the event, from Mega Greninja's Surf+ to Mega Dragonite's Outrage+. Pokémon that reach Super Max Level now keep an additional Charged Attack while Mega Evolved, with attack power scaling by Mega Level.
Will Shiny Armored Mewtwo be available?
No. Nintendo Insider confirms that Shiny Armored Mewtwo will not be available during Pokémon GO Fest: Mega Finale. Trainers should set expectations accordingly and focus on securing a standard Armored Mewtwo if they want one for their collection.
