Mega Mewtwo X is a Psychic/Fighting-type Legendary Pokémon in Pokémon GO, arriving via Super Mega Raids during GO Fest 2026. It holds a 343 base Attack stat, dual-type offensive coverage across Fighting and Psychic, and the ability to Mega Evolve from any Mewtwo already in a trainer’s collection.
Mega Mewtwo X is weak to Fairy, Flying, and Ghost-type moves, all hitting at 1.6x damage. Mega Rayquaza, Necrozma (Dawn Wings), and Mega Gengar are the top-rated counters. Counter and Focus Blast is the best Fighting-type moveset, while Mega Mewtwo Y outperforms it in the Psychic attacker role. Max CP reaches 4,724 at level 50 with Best Buddy status.
This review breaks down counters, movesets, CP ranges, shiny availability, Mega Energy costs, and how Mega Mewtwo X compares to its Y counterpart. By the end, you’ll know exactly whether it belongs in your raid lineup and where to invest your Mega Energy first for maximum battle impact.
What Is Mega Mewtwo X in Pokémon GO?
Mega Mewtwo X is a Psychic/Fighting-type Legendary Pokémon available in Pokémon GO through Mega Evolution. It enters the game with one of the highest Attack stats of any Pokémon, combining raw power with dual-type offensive coverage that few other Megas can match.
Here’s the thing: the base Attack stat sits at 343. That number puts Mega Mewtwo X in the top tier of all raid attackers, regardless of type. Stamina and Defense stats are similarly elite. Mega Mewtwo X is a durable presence in any raid lineup.
In fact, Mega Mewtwo X debuted during Pokémon GO Fest 2026 via Super Mega Raids. Trainers need Mega Mewtwo X Energy, a distinct resource separate from standard Mega Energy, to activate the Mega Evolution.
How Does Mega Evolution Work for Mewtwo?
Mega Mewtwo X requires Mega Mewtwo X Energy collected exclusively from Super Mega Raid Battles. This energy type is separate from standard Mega Energy and cannot be substituted with energy from other Pokémon.
And here’s what most trainers don’t realize: the Mega form is temporary. Trainers must re-activate it for each use. However, reaching higher Mega Levels reduces the cooldown period between activations, making frequent use more practical over time.
The good news? A special bonus applies during Pokémon GO Fest 2026. Every Mega Mewtwo caught from GO Fest raids comes with Mega Level 1 already unlocked. This removes the initial 200-energy cost for first-time evolution.
What Type Is Mega Mewtwo X?
Mega Mewtwo X is Psychic and Fighting-type, distinguishing it from Mega Mewtwo Y, which is purely Psychic-type. The Fighting subtype fundamentally changes its raid role and counter matchups.
The Fighting typing expands offensive coverage significantly. Mega Mewtwo X deals super-effective damage to Normal, Rock, Steel, Ice, and Dark-type Pokémon in addition to Psychic-type targets. That versatility makes it viable across a wider range of raid bosses.
The dual typing introduces extra weaknesses. Fairy, Flying, and Ghost-type moves all deal super-effective damage, giving raid attackers more options to exploit compared to a mono-Psychic defender.
What Are Mega Mewtwo X’s Weaknesses?
Mega Mewtwo X is weak to Fairy, Flying, and Ghost-type moves due to its Psychic/Fighting dual typing. Raid teams built around these three types will deal super-effective damage and clear the encounter significantly faster.
To be clear, Ghost-type moves carry a 1.6x multiplier against Mega Mewtwo X. That makes Mega Gengar and Necrozma (Dawn Wings) two of the most effective counters available. Both pair high base Attack with STAB Ghost-type movesets.
Fairy-type attacks also hit at the 1.6x super-effective rate. Mega Gardevoir and Togekiss bring strong Fairy coverage and rank in the top-10 counter lists published by Pokebattler for this raid.
Mega Mewtwo X Type Weaknesses:
| Weakness Type | Damage Multiplier | Top Counter Examples |
|---|---|---|
| Ghost | 1.6x | Mega Gengar, Necrozma (Dawn Wings) |
| Fairy | 1.6x | Mega Gardevoir, Togekiss |
| Flying | 1.6x | Shadow Moltres, Mega Rayquaza |
Is Mega Mewtwo X Weak to Fairy-Type Moves?
Yes. Mega Mewtwo X is weak to Fairy-type moves because the Fighting type carries an inherent Fairy weakness in Pokémon GO’s type chart. Fairy attacks hit at the 1.6x super-effective multiplier, making Fairy-type counters genuinely impactful.
Mega Gardevoir with Charm and Dazzling Gleam is rated A-tier by Pokebattler for Mega Mewtwo X raids. The combination delivers sustained Fairy-type DPS well above neutral attackers.
Don’t have Mega Gardevoir? Clefable with Charm and Moonblast offers a budget alternative. It lacks the raw damage output of Mega Gardevoir but remains viable for larger raid groups.
Does Weather Affect Mega Mewtwo X Raids?
Weather directly influences attacker and defender performance in Mega Mewtwo X raids by boosting specific move types. Choosing counters that align with active weather conditions can meaningfully increase team damage output.
Windy weather boosts Psychic-type moves. Psychic-type attackers like Mega Mewtwo Y and Espeon deal 20% more damage in this condition. Mega Mewtwo X’s own Psychic-type attacks also gain the weather bonus when used offensively in other raids.
Cloudy weather boosts both Fighting-type and Fairy-type moves. This is the best weather condition for Fairy counters like Mega Gardevoir, simultaneously amplifying both attack and boss fighting-type moves by 20%.
What Are the Best Counters for Mega Mewtwo X?
Mega Rayquaza, Necrozma (Dawn Wings), and Mega Gengar are the top-tier S-rated counters for Mega Mewtwo X according to Pokebattler’s raid analysis. Each combines elite base Attack stats with super-effective STAB moves against the Psychic/Fighting typing.
Here’s why type matters: the counter priority follows type effectiveness. Fairy, Flying, and Ghost-type attackers all hit at 1.6x. Top counters pair these types with high base Attack, making them far more efficient than neutral-damage alternatives.
And here’s where it gets interesting. Shadow Pokémon also rank highly in counter lists. Shadow Moltres and Shadow Salamence both appear in the top-10 due to the 20% attack bonus that Shadow status provides, though the trade-off is reduced survivability.
Which Pokémon Counter Mega Mewtwo X Best?
Mega Rayquaza ranks among the highest-damage counters for Mega Mewtwo X, with a base Attack stat of 345 and strong Flying-type coverage. Dragon Tail and Dragon Ascent deliver top-tier neutral-to-super-effective damage across the encounter.
Top Mega Mewtwo X Counters:
- Mega Rayquaza (Dragon Tail / Dragon Ascent) – A-tier generalist
- Necrozma Dawn Wings (Shadow Claw / Shadow Ray) – A-tier Ghost counter
- Mega Gengar (Shadow Claw / Shadow Ball) – A-tier Ghost counter
- Shadow Moltres (Wing Attack / Sky Attack) – top-5 Flying counter
- Mega Gardevoir (Charm / Dazzling Gleam) – A-tier Fairy counter
In fact, Necrozma (Dawn Wings) with Shadow Claw and Shadow Ray delivers exceptional Ghost-type damage output. Pokebattler ranks it as one of the two best Ghost counters for this raid alongside Mega Gengar.
Do Shadow Pokémon Outperform Mega Counters?
Shadow Pokémon deal approximately 20% more damage than their standard forms but have 20% reduced Defense. The result is a speed-versus-survivability tradeoff. They outperform Megas in raw damage per second but require larger raiding groups to compensate for faster fainting.
Bottom line: Shadow Salamence appears in Pokebattler’s viable counter list. Its damage output is strong but falls short of S-tier Megas in overall efficiency for duo or small-group attempts.
Mega Pokémon provide a unique advantage Shadow forms cannot match. Activating a Mega counter boosts all party members’ attacks of the same type by 30%, making Mega counters more team-efficient when coordinating with others.
What Is the Best Moveset for Mega Mewtwo X?
Counter and Focus Blast is the recommended moveset for Mega Mewtwo X when used as a Fighting-type attacker, per Pokémon GO Hub’s moveset analysis. This combination maximizes Fighting-type DPS against Dark, Normal, Steel, Ice, and Rock-type raid bosses.
That said, Mega Mewtwo X also runs a competitive Psychic-type moveset. Confusion and Psystrike delivers high Psychic DPS, though Mega Mewtwo Y outperforms this combination due to its higher base Attack and pure Psychic typing.
The dual-typing creates genuine moveset flexibility. Trainers can run either Fighting or Psychic fast moves depending on the target, making Mega Mewtwo X adaptable across more raid matchups than most single-type Mega attackers.
Mega Mewtwo X Moveset Comparison:
| Role | Fast Move | Charged Move | Best Against |
|---|---|---|---|
| Fighting attacker | Counter | Focus Blast | Dark, Normal, Steel, Ice, Rock |
| Psychic attacker | Confusion | Psystrike | Poison, Fighting types |
| Ghost coverage | Counter | Shadow Ball | Psychic, Ghost-resistant targets |
Which Fast Move Should You Choose?
Counter is the superior fast move for Fighting-type performance, generating 3.5 Energy Per Turn while dealing 8 damage per use. That combination of Energy generation and damage output makes it the most efficient Fighting-type fast move available to Mega Mewtwo X.
Confusion delivers 20 base damage with 3.0 Energy Per Turn. It is the correct choice when running a Psychic-type configuration, particularly against targets like Toxicroak or Machamp where Psychic super-effectiveness applies.
So, the decision depends on the target type. Counter fits raids where Fighting deals super-effective damage. Confusion fits raids where Psychic is more valuable. Mega Mewtwo X can adapt to either role with a single Charged TM if needed.
Which Charged Move Is Best for Raids?
Focus Blast is the top charged move for Fighting-type configurations, dealing 140 base damage against targets weak to Fighting. The high base damage makes it devastating in matchups where Fighting-type coverage is super-effective.
Here’s the kicker: Psystrike is a legacy charged move with 90 base damage and 45 energy cost. Its low energy cost and high damage per use make it the most efficient Psychic-type charged move in Mega Mewtwo X’s kit, though it requires a Legacy TM to obtain.
Shadow Ball adds Ghost-type coverage for 100 base damage. It is a strong third option against targets resistant to both Psychic and Fighting moves, giving Mega Mewtwo X broader neutral coverage than most specialized Mega attackers.
How Does Mega Mewtwo X Compare to Mega Mewtwo Y?
Mega Mewtwo Y is a pure Psychic-type with a higher base Attack stat of 353 compared to Mega Mewtwo X’s 343. That higher stat makes Mega Mewtwo Y the stronger option specifically for Psychic-type raid roles. For any raid requiring Psychic-type damage, Mega Mewtwo Y delivers higher output.
But here’s where Mega Mewtwo X wins: it holds the advantage in Fighting-type scenarios. As the strongest Fighting-type Mega attacker in Pokémon GO, it has no direct competition from Mega Mewtwo Y when targeting Normal, Dark, Steel, or Ice-type raid bosses.
As a generalist, Mega Mewtwo X still ranks in the top five in Pokémon GO. It performs effectively against nearly any raid target, though it consistently finishes just below Mega Mewtwo Y and Mega Rayquaza in overall DPS output.
Mega Mewtwo X vs Mega Mewtwo Y Comparison:
| Attribute | Mega Mewtwo X | Mega Mewtwo Y |
|---|---|---|
| Type | Psychic/Fighting | Psychic |
| Base Attack | 343 | 353 |
| Best role | Fighting attacker | Psychic attacker |
| Generalist rank | Top 5 | Top 3 |
Is Mega Mewtwo X Worth Using Over Mega Mewtwo Y?
Yes. Mega Mewtwo X is worth using specifically as the best Fighting-type Mega attacker in Pokémon GO, filling a distinct raid role that Mega Mewtwo Y cannot replicate. Trainers targeting Fighting-weak raid bosses have no better Mega option.
Now here’s the thing: the investment decision depends on available Mewtwo resources. Trainers with only one Mewtwo must choose between Mega X for Fighting coverage or Mega Y for Psychic dominance. Both forms require Mega Level progression through the same Mewtwo.
Pokémon GO Hub rates Mega Mewtwo X as a top-five generalist. It delivers competitive performance across most raid scenarios, making the investment worthwhile even for trainers who already have Mega Mewtwo Y powered up.
What Is Mega Mewtwo X’s Max CP in Pokémon GO?
Mega Mewtwo X reaches a maximum CP of approximately 4,724 at level 50 with Best Buddy status and maximum XL Candy investment. That makes it one of the highest CP Pokémon available in the game.
Mega Mewtwo X CP Levels:
| Level | CP Range | Notes |
|---|---|---|
| 20 (normal catch) | ~2,082-2,167 | Standard raid catch floor/ceiling |
| 25 (weather boost) | ~2,600-2,708 | Boosted raid catch range |
| 40 (standard max) | ~4,178 | Max with standard candy |
| 50 (Best Buddy + XL) | ~4,724 | Absolute max CP |
And that’s not all. Weather-boosted Mega Mewtwo X caught from raids has a higher CP floor at level 25. This allows trainers to obtain specimens closer to the powered-up maximum with less Candy and Stardust investment.
How Much Mega Energy Does Mega Mewtwo X Require?
Mega Mewtwo X requires 200 Mega Mewtwo X Energy for the initial Mega Evolution, a cost higher than most standard Mega Pokémon. This specific energy type cannot be substituted with energy from other Pokémon.
To be specific, Mega Mewtwo X Energy comes from defeating Mega Mewtwo X or Mega Mewtwo Y in Super Mega Raid Battles during eligible events. Each raid completion awards a set amount of this specialized energy.
GO Fest 2026 attendees received a meaningful discount. Mega Mewtwo caught during GO Fest events came with Mega Level 1 already unlocked, eliminating the 200-energy initial cost and allowing immediate Mega Evolution at no energy charge.
Is Shiny Mega Mewtwo X Available in Pokémon GO?
Yes. Shiny Mega Mewtwo X is available in Pokémon GO, with the shiny form displaying a visually distinct color palette from the standard blue-and-grey version. Shiny Mewtwo retains its shiny status when Mega Evolved.
Here’s what you need to know: shiny Mewtwo can only be encountered through raid battles. Egg hatching, research tasks, and field encounters do not yield shiny Mewtwo. Trainers must defeat Mega Mewtwo X in a raid to trigger a shiny encounter opportunity.
So what does that mean for your odds? Legendary raids carry an approximate 1-in-20 shiny encounter rate, roughly 5%. Most trainers encounter a shiny Mewtwo within 20 completed raids, though individual results vary with each attempt being an independent chance.
How Do You Catch Mega Mewtwo X?
Trainers must first defeat Mega Mewtwo X in a Super Mega Raid Battle before receiving the standard Mewtwo encounter needed to attempt a catch. Winning the raid is required; there is no alternative encounter method.
For context, Super Mega Raids were first accessible at Pokémon GO Fest 2026 in-person events in Tokyo, Chicago, and Copenhagen. The encounter expanded globally during the GO Fest 2026 Global event later in the year.
Maximizing catch probability requires Golden Razz Berries and Excellent Curveball throws. Mewtwo has a base catch rate of approximately 10% at standard conditions. Excellent throws combined with Golden Razz Berries raise the effective catch probability to roughly 15-20% per throw.
Steps to Maximize Catch Rate:
- Use a Golden Razz Berry before each throw attempt.
- Wait for the attack animation to complete before throwing.
- Land an Excellent Curveball throw inside the smallest circle.
- Activate a Silver Pinap Berry if you want both Candy and higher catch rate.
