Trying to decide whether to prioritize Mega Mewtwo X or Mega Mewtwo Y first? Getting access to both forms in one event cycle changes team planning immediately.
This guide covers the unlock path for the Project M side mission, the captured Mewtwo's actual stats, matchup roles for each Mega form, and practical roster templates so you can commit to the right Mega lane early.
Jump to the sections you need for mission flow, IV and moveset details, form comparison, and competitive build direction.
The headline value is dual access: Mega X and Mega Y give one Legendary slot two very different strategic identities, and Project M hands you the Pokémon plus both stones in a single post-game loop.
PokemonLore will continue updating Project M notes, IV-optimization tips, and build guidance so you can extract real ladder value from both forms, not just collect them.
Frequently Asked Questions
Which Mega Mewtwo form is better for competitive play?
Both forms are top-tier competitive choices. Mega Mewtwo Y has higher overall power with unmatched Special Attack, while Mega Mewtwo X offers better type coverage against Dark-types and physical walls. The choice depends on your team composition and current meta trends.
What's the difference between Mega Mewtwo X and Mega Mewtwo Y?
Mega Mewtwo X becomes Psychic/Fighting-type with a focus on physical attacks (Attack stat boost), while Mega Mewtwo Y remains pure Psychic with the highest Special Attack stat in the game. Choose based on your team's needs and preferred playstyle.
Does the captured Mewtwo have good IVs?
Yes — every Project M Mewtwo has three random perfect IVs locked in at capture, but nature and the remaining IVs are random. Because autosave can't be turned off, the cleanest approach is to make a Backup Save before the fight and soft-reset for nature, then Bottle Cap and Mint the rest of the spread.
Where does the Project M mission start?
Project M (Side Mission EX2) begins at Lysandre Café in the Magenta District. Speak to Mable there, then take the elevator down to Lysandre Labs and navigate to Floor B3F. The cutscene triggers when you approach the central computer terminal.
How do I get Mewtwo in Pokémon Legends: Z-A?
Claim Mewtwonite X and Mewtwonite Y via Mystery Gift (Link Play > Mystery Gift > Get via Internet), finish the main story, then head to Lysandre Café in the Magenta District and speak to Mable to start Side Mission EX2: Project M. Take the elevator down to Lysandre Labs B3F and approach the computer terminal to trigger the Level 70 Mewtwo encounter.
What happens if I accidentally knock out Mewtwo?
You get another chance. Legends: Z-A lets you re-attempt the Project M catch if Mewtwo faints, so there's no need to panic over a misclicked Psystrike — reload into the encounter and try again with weaker moves or status support.
Do I need to complete the story first?
Yes — you must finish the main storyline of Pokémon Legends: Z-A before Project M becomes available. You can claim the Mewtwonite stones via Mystery Gift at any time, but the Mewtwo encounter itself is locked behind story completion.

Psychic-type strategies
Life Orb Flex (Non-Mega Mewtwo)
Item: Life Orb. Nature: Modest. EV spread: 252 HP / 252 Sp.Atk / 4 Spe. Moves: Psychic, Aura Sphere, Ice Beam, Nasty Plot. A strong option when you want to reserve your Mega slot for another Pokémon — Life Orb keeps damage output competitive across the BoltBeam-adjacent coverage.
Physical Sweeper (Mega Mewtwo X)
Item: Mewtwonite X. Nature: Jolly (+Spe, -Sp.Atk). EV spread: 4 HP / 252 Atk / 252 Spe. Moves: Close Combat, Zen Headbutt, Stone Edge, Bulk Up. Set up one Bulk Up and clean teams that rely on physical walls, with Fighting STAB punishing Dark-type checks.
Special Sweeper (Mega Mewtwo Y)
Item: Mewtwonite Y. Nature: Modest (+Sp.Atk, -Atk). EV spread: 252 HP / 252 Sp.Atk / 4 Spe. Moves: Psychic, Psyshock, Shadow Ball, Nasty Plot. One Nasty Plot turn is usually enough to sweep; Psyshock punches through specially defensive walls while Shadow Ball covers opposing Psychics and Ghosts.

Your Captured Mewtwo: Level, IVs, Nature, and Moves

Psychic, Aura Sphere, Amnesia, Psycho Cut

Encounter profile
Use a Backup Save for soft resets:
Autosave cannot be disabled in Legends: Z-A, so make a Backup Save right before approaching the computer terminal if you want to reset for a better nature or IV spread.
Bottle Cap the rest:
With three perfect IVs already locked in, three Bottle Caps are enough to Hyper Train Mewtwo to full 31s in the other stats — much faster than soft-resetting for a 6-perfect roll.
Fix nature and ability later:
Use a Mint to reshape the stat spread for your intended set (Modest for Mega Y, Jolly for Mega X) and an Ability Capsule if you want to swap between Pressure and Unnerve.
IV optimization tips
Two Paths to Power: Mega Mewtwo X and Y
Mewtwo is one of only two Pokémon (alongside Charizard) that can Mega Evolve into two distinct forms, each with dramatically different stat distributions, typings, and battle roles.
Your choice between Mega Mewtwo X and Y should depend on your team composition and battle strategy. Mega Mewtwo X handles Dark-types better thanks to Fighting coverage, while Mega Mewtwo Y offers unmatched special sweeping potential.
Mega Mewtwo X
Gains the Fighting type and transforms into a physical attacker with exceptional Attack and Speed stats. Excels at breaking through defensive walls with Close Combat, Drain Punch, and Zen Headbutt. The Psychic/Fighting typing provides excellent neutral coverage and a better match-up against Dark-types.
Focus:
Physical Attack
Type:
Psychic/Fighting
Mega Mewtwo Y
Remains pure Psychic-type but gains the highest Special Attack stat in the entire game. Devastates opponents with Psystrike, Ice Beam, Focus Blast, and Aura Sphere. The streamlined design emphasizes overwhelming special power.
Focus:
Special Attack
Type:
Pure Psychic
How to Obtain Mewtwo and the Mega Stones
Important: the Mewtwonite X and Mewtwonite Y Mystery Gift runs for a limited period, so claim both stones as soon as possible. You can receive the stones before finishing the story, but Project M itself will not appear until the credits have rolled and the stones are in your satchel.
The battle on Lysandre Labs B3F features a Level 70 Mewtwo with a diverse movepool (Psychic, Aura Sphere, Amnesia, Psycho Cut). Bring Ultra Balls, Timer Balls, and Pokémon with status moves like Sleep or Paralysis to improve your capture chances. If you accidentally knock Mewtwo out, the game lets you retry the encounter — failure is forgiving here.
Clearing Project M rewards you with ₽10,000, one Exp. Candy XL, and the captured Mewtwo itself.
Access Mystery Gift:
From the main menu, select 'Link Play' and then choose 'Mystery Gift' to begin the distribution process.
Get via Internet:
Select 'Get via Internet' to automatically download both Mewtwonite X and Mewtwonite Y to your game save. Save the game afterwards so both stones remain in your satchel.
Finish the main story:
Project M is Side Mission EX2 — a post-game mission that only unlocks after the main story credits roll. With both Mewtwonite stones in your satchel, the mission becomes available.
Start Project M at Lysandre Café:
Head to Lysandre Café in the Magenta District and speak to Mable to accept Project M. Take the elevator down to Lysandre Labs.
Descend to Lysandre Labs B3F:
Make your way down to Floor B3F and approach the central computer terminal. A cutscene triggers and a Level 70 Mewtwo appears — catch it to complete the mission.

The Legendary Return: Official Reveal
The Pokémon Company unveiled Mewtwo's return to the franchise on December 2, 2025, pairing a special Mystery Gift distribution of Mewtwonite X and Mewtwonite Y with a brand-new post-game side mission called Project M. This legendary Pokémon, first discovered in the Kanto region, has been a cornerstone of competitive battling since Generation I.
Mewtwo is renowned as one of the most powerful Pokémon ever created, born from genetic experiments on the Mythical Pokémon Mew. Its exceptional Special Attack (base 154), Speed (base 130), and versatility make it a top-tier choice for competitive teams across all battle formats.
The reveal video showcases both Mega Evolution forms in action within the Mega Dimension, demonstrating the stark contrast between Mega Mewtwo X's physical prowess and Mega Mewtwo Y's overwhelming special power. This dual-form approach offers unprecedented team-building flexibility.
