Armored Mewtwo is back in Pokémon Go for the first time in six years, headlining five-star raids during the Go Fest 2026: Mega Finale weekend. It is a pure Psychic-type Legendary with a heavily armored build, so the fight rewards raw super-effective damage rather than clever play. Here is how to take it down and add it to your Pokédex.
Quick answer: Armored Mewtwo is a Psychic-type five-star raid boss weak to Ghost, Dark, and Bug. Fill your party with strong Ghost and Dark attackers such as Dawn Wings Necrozma and Mega Gengar, raid with 5 to 8 trainers, then catch it afterward. There is no shiny version.
When Armored Mewtwo appears in Pokémon Go
Armored Mewtwo appears in five-star raids on Saturday, September 5th and Sunday, September 6th, from 10am to 6pm local time. This is part of the Go Fest 2026: Mega Finale event, which runs a packed schedule of raids across the weekend.
Because the raid window is short and shared with a lot of other bosses, it is worth lining up your lobbies in advance. You can host or join Armored Mewtwo raids remotely, and there is no Remote Raid Pass limit during the Mega Finale event. No official return date beyond this weekend has been confirmed, so treat this as your window to catch it.
Armored Mewtwo type and weaknesses
Armored Mewtwo is a pure Psychic-type, which gives it exactly three weaknesses. It also resists two common attacking types, so avoid bringing Fighting or Psychic damage into the fight.
| Property | Detail |
|---|---|
| Type | Psychic |
| Weak to | Bug, Dark, Ghost (160% damage) |
| Resists | Fighting, Psychic (62.5% damage) |
| Weather boost | Windy |
Dark and Ghost give you the best selection of attackers, since those types have more powerful Legendaries, Mega Evolutions, and Shadow variants than Bug. Bug is still fine as a weakness, but its strongest options lean heavily on Megas and Ultra Beasts.
Best Armored Mewtwo counters
Dawn Wings Necrozma is the single strongest counter if you have it powered up. It hits hard as a Ghost-type and is bulky enough to survive Armored Mewtwo’s attacks better than glassier options. Mega Gengar is the easiest premium pick and boosts the Ghost attackers around it, while Mega Tyranitar is a sturdy, dependable Dark option.
| Pokémon | Fast move | Charged move |
|---|---|---|
| Dawn Wings Necrozma | Psycho Cut | Moongeist Beam |
| Mega Gengar | Shadow Claw | Shadow Ball |
| Mega Tyranitar | Bite | Brutal Swing |
| Shadow Hydreigon | Bite | Brutal Swing |
| Mega Houndoom | Snarl | Dark Pulse |
| Shadow Darkrai | Snarl | Shadow Ball |
| Origin Forme Giratina | Shadow Claw | Shadow Force |
| Mega Absol | Snarl | Brutal Swing |
Mega Gengar and Mega Absol hit extremely hard but are fragile, so expect them to faint quickly if Armored Mewtwo targets them. Mega Tyranitar and Shadow Hydreigon strike a better balance between damage and survivability thanks to the Bite and Brutal Swing Dark combo.
Budget counters that still work
You do not need a full team of Megas and Shadows. Several regular attackers perform well and are easier to build.
| Pokémon | Fast move | Charged move |
|---|---|---|
| Hydreigon | Bite | Brutal Swing |
| Tyranitar | Bite | Brutal Swing |
| Darkrai | Snarl | Shadow Ball |
| Chandelure | Hex | Shadow Ball |
| Dragapult | Astonish | Shadow Ball |
| Gholdengo | Hex | Shadow Ball |
| Kingambit | Snarl | Foul Play |
| Weavile | Snarl | Foul Play |
Note: You can technically use Mega Mewtwo X or Y with Shadow Ball, but it is not recommended. Both are primarily Psychic-type, so they miss the attack bonus that Ghost and Dark Megas provide to the lobby, and Mega Mewtwo X is also part Fighting, a type Armored Mewtwo resists.
How many trainers you need
The problem with Armored Mewtwo is not surviving it, it is chewing through its huge Defense and HP before the timer runs out. With low Attack, it rarely wipes a team, so the fight can drag if your damage is thin.
| Group size | Difficulty |
|---|---|
| 3–4 trainers | Possible with strong, well-built counters |
| 5–8 trainers | Recommended and comfortable |
| 9+ trainers | Very easy |
Three trainers is the absolute minimum, and only if everyone brings top counters. If you are raiding with random players, wait for at least five others unless the lobby is clearly stacked with upgraded Mewtwo counters.
Armored Mewtwo CP after the raid
The raid boss sits at 41,299 CP. Once you win, the CP of your catch encounter tells you how strong it is before you throw a single ball. Windy weather boosts the encounter to Level 25 and raises the CP range.
| Condition | CP range | 100% IV CP |
|---|---|---|
| Normal (Level 20) | 1,740–1,821 | 1,821 |
| Windy weather (Level 25) | 2,175–2,276 | 2,276 |
A 1,821 CP normal catch or a 2,276 CP weather-boosted catch is a guaranteed 100% IV. Armored Mewtwo maxes out at 3,603 CP at Level 50.
Best Armored Mewtwo moveset
For the Armored Mewtwo you catch, the best moveset is Confusion as its Fast Attack and Psystrike as its Charged Attack. Psystrike is a legacy move, so you will need an Elite Charged TM to teach it. If you do not have one, Future Sight is a solid alternative Charged Attack.
| Move type | Options |
|---|---|
| Fast moves | Confusion (Psychic), Iron Tail (Steel) |
| Charged moves | Psystrike (Psychic), Future Sight (Psychic), Dynamic Punch (Fighting), Earthquake (Ground), Rock Slide (Rock) |
Armored Mewtwo is a poor raid attacker because its armor trades Attack for bulk, so it deals less Psychic damage than most alternatives. Its real strength is PvP. With high Defense and HP, it performs strongly in the Ultra League, where Confusion paired with the cheap Psystrike and Dynamic Punch gives it flexible, hard-hitting coverage across shield scenarios.
Is Armored Mewtwo shiny?
No. There is no shiny Armored Mewtwo in Pokémon Go right now, so every one you catch this weekend will be the regular form. That is the trade-off for its return after such a long absence, and it means there is nothing extra to hunt for beyond a high-IV catch.
Stats that make Armored Mewtwo different
Armored Mewtwo is the only costume Pokémon with base stats that differ from its original counterpart. The armor pushes its Defense far above regular Mewtwo while dropping its Attack, which is exactly why it excels on defense and in PvP rather than as a raid damage dealer.
| Stat | Value |
|---|---|
| Attack | 182 |
| Defense | 278 |
| Stamina | 214 |
With the weekend window being short and no confirmed return date after it, this is the moment to grab an Armored Mewtwo. Bring your best Ghost and Dark attackers, raid in a group of five or more, and aim for that top-end IV catch before the timer closes.
