Defeating Mega Mewtwo Y in Pokemon Go requires a focused team of Ghost and Dark-type attackers, paired with defensive positioning and proper raid coordination. Mega Mewtwo Y’s Psychic typing makes it vulnerable to a narrow set of counters, meaning trainer preparation centers on assembling the strongest viable options rather than having flexibility. The raid typically demands multiple trainers working together, though the exact difficulty depends heavily on individual team power and the move sets your attackers carry into battle.
Mega Mewtwo Y stands apart from standard raid bosses because it combines high damage output with the defensive advantages of its Mega Evolution form. If you enter this raid without ghost or dark-type specialists, you’ll find yourself in a prolonged battle where your team faints before dealing meaningful damage. The most successful strategy focuses on maximizing your attackers’ offensive potential while accepting that some will fall during the fight.

What Are the Best Counters for Mega Mewtwo Y?
Ghost-type pokemon consistently perform as top-tier counters, with species like Gengar, Chandelure, and Banette delivering strong super-effective damage. Gengar in particular remains relevant due to its dual Ghost and Poison typing, allowing it to benefit from STAB (Same Type Attack Bonus) on Ghost-type moves while maintaining reasonable bulk for a glass cannon. Chandelure offers higher raw damage output but requires more careful positioning to avoid unnecessary faints before the raid timer expires.
Dark-type attackers form the second pillar of your raid team, with Hydreigon, Weavile, and Houndoom providing solid alternatives when your Ghost-type roster fills up. Hydreigon’s Dragon and Dark typing gives it excellent coverage against multiple raid boss archetypes, making it a versatile investment beyond this specific encounter. The gap between top-tier Dark attackers and secondary options is more pronounced than with Ghost types, so prioritizing your Dark-type team composition matters considerably.
Understanding Type Advantages and Defensive Considerations
mega Mewtwo Y’s Psychic typing creates a straightforward weakness matrix, but the raid’s difficulty emerges from the boss’s offense rather than its defenses. A single Mega Mewtwo Y strike can eliminate a moderately trained attacker in two or three hits, meaning you cannot simply bring your strongest Pokemon regardless of type and expect survival. This defensive pressure forces trainers to build teams expecting multiple faints, which requires either rotating fresh Pokemon into battle or accepting that some raid damage will go uncontested during transition periods.
The boss’s potential move set matters enormously for raid outcomes. Fast attacks like Confusion deal consistent chip damage to your team, while charged attacks such as Psychic or Aura Sphere can trigger team-wipes if trainers aren’t actively dodging. Trainers who focus exclusively on damage output while ignoring the dodge mechanic often watch their entire team collapse before the raid timer reaches critical stages, losing opportunities to revive and rejoin the battle.
Building Your Raid Attack Team
Your optimal raid team should include at least three to four fully powered Ghost-type specialists, supplemented by two to three dark-type alternatives. Investing Stardust into your top-tier counters—raising them to level 40 or higher—directly correlates with faster raid completion and fewer trainer faints. If you possess legacy move sets on older Pokemon like Gengar with Shadow Ball and Sludge Bomb, these outdate newer acquisitions that learned different charge attacks through more recent move pool updates.
Team composition also depends on your raid group’s collective strength. A team of five highly trained trainers might comfortably defeat Mega Mewtwo Y with less optimization than a pair of trainers using similar Pokemon. This variance means your personal preparation level should assume you’re working with a moderately-sized group rather than an overwhelming horde, which forces realistic team building rather than theoretical extremes.
Pre-Raid Resource Management and Preparation
Before entering a Mega Mewtwo Y raid, verify that your attacking Pokemon have recently charged moves at full power and that you possess adequate healing items. Running out of Super Potions mid-raid forces you to either leave the battle to restock or watch fainted Pokemon remain sidelined for the raid’s duration. Many trainers underestimate their healing item consumption in extended raids, arriving unprepared despite possessing strong attacking teams.
Consider provisioning revives specifically for this raid, rather than relying on your standing stockpile. A single raid might consume six to eight revives if your team faints repeatedly, and purchasing them with Pokécoins on short notice defeats the resource-efficient approach most trainers maintain. If your account recently spent healing items on different content, taking an extra fifteen minutes to farm Pokéstops before the raid prevents mid-encounter resource crises.
Common Mistakes That Extend Raid Duration
Trainers frequently neglect type coverage in pursuit of raw damage stats, bringing a Hydreigon or Weavile as primary attackers when their Ghost-type bench is genuinely deeper. The attack power gap between optimized Ghost attackers and secondary dark types matters less than trainers assume—a fully trained Chandelure typically outperforms a level-30 Weavile by a notable margin. Chasing marginal damage improvements at the cost of abandoning type advantage creates longer battles that test team endurance rather than optimization.
Another persistent error involves attempting this raid with trainers whose accounts lack sufficient investment in either Ghost or Dark type Pokemon. Attempting Mega Mewtwo Y raids as preparation for future legendary raids represents a fundamentally different approach than entering with established counters. This isn’t necessarily wrong, but trainers should acknowledge they’re prioritizing experience over efficiency, and adjust their group size expectations accordingly.
Solo and Small Group Raid Viability
Mega Mewtwo Y raids are functionally impossible to complete solo for most trainers, requiring coordinated groups to meet the damage threshold before the timer expires. Even players with maxed-out raid teams and legacy move sets cannot sustain the necessary damage output over extended periods—the raid’s design assumes multiple attackers sharing the offensive load. This distinction matters for trainers planning their raid day strategy, as attempting this encounter solo wastes raid passes that could target achievable objectives.
Small groups of two to three trainers can defeat Mega Mewtwo Y if the participants possess well-built attacking teams, but the margin for error shrinks considerably. A single trainer fainting repeatedly creates cascading problems, as the raid boss continues dealing damage to the remaining team while the affected trainer regroups. This interdependency means small group success depends more heavily on individual preparation than larger raid groups, where one weak link becomes less consequential.
Post-Raid Optimization and Future Encounters
After completing your first Mega Mewtwo Y raid, subsequent encounters become progressively easier as you accumulate Mega Energy for the boss itself. Using Mega Mewtwo Y as an attacker in future raids against opponents weak to Psychic typing creates a feedback loop where initial preparation yields long-term advantages. However, trainers should verify that their Mega Mewtwo Y possesses an offensive move set rather than defensive coverage moves, as suboptimal move rolls eliminate the attacking advantage.
The candies and Mega Energy earned from defeating Mega Mewtwo Y should be reinvested strategically rather than distributed across your entire collection. Prioritizing evolution and power-ups for your core raid team generates measurable improvements in future encounters, while scattering resources across marginal Pokemon produces minimal benefit. This focused investment approach transforms raid success from individual encounter victories into sustained progression across your account’s entire raid calendar.
