Why Is Mew Locked Behind a Permanent Story Quest?

Mew, the mythical Psychic-type, can only be obtained through A Mythical Discovery -- here's the full 8-stage guide.

This guide covers why is mew locked behind a permanent story quest?. Follow the step-by-step instructions below for mythical_pokemon strategies, tips, and best practices.

Why Is Mew Locked Behind a Permanent Story Quest?

Key Takeaways

  • Mew is only available through "A Mythical Discovery" Special Research — an 8-stage permanent quest available since March 30, 2018
  • Requires Level 15+, catching Ditto, Gold Kanto Medal, and Magikarp evolution
  • Mew encounter is guaranteed catch (100% catch rate, unlimited balls, cannot flee)
  • Shiny Mew is only available through paid events (GO Tour Kanto, GO Fest)
  • Cannot be traded — every trainer must complete the quest individually
  • Takes 2-4 weeks of active play to complete

Bottom Line: Mew's permanent story-lock prevents mass distribution, making it one of the rarest and most exclusive Pokemon in the game.

Why Mew Is Story-Gated

The Only Way to Get Mew

Mew is exclusively available through A Mythical Discovery:

No raids • No wild encounters • No trades • No events
ONLY: Complete the 8-stage Special Research quest

This quest has been permanent since March 30, 2018 — it's always available, but only for trainers Level 15+.

Why No Shortcuts?

Niantic made Mew story-exclusive for several reasons:

  1. Mythical Status: Mew is a Mythical Pokemon, a tier above Legendary. In the main-series games, Mythicals are event-only.
  2. Scarcity Marketing: If Mew were available in raids or events, everyone would have one. Story-locking makes it exclusive.
  3. Player Investment: The 8-stage quest requires time, effort, and skill (Great Throws, Ditto hunting, Kanto Medal). Players who complete it are invested.
  4. No Trading: Mew cannot be traded, so each account must complete the quest independently.

Mew is a badge of dedication — you can't buy it, borrow it, or inherit it.

The 8-Stage Quest

Stage Overview

Stage Key Tasks Estimated Time
1/8 Spin 5 PokeStops, Catch 10 Pokemon, Transfer 5 Pokemon 1–2 hours
2/8 Buddy candy (2), 10 Great Throws, Hatch 3 Eggs 1–3 days (Egg walking)
3/8 Reach Level 15, Battle in Gyms (2), Battle in Raids (2) 1–7 days (leveling)
4/8 Silver Kanto Medal, Evolve 20 Pokemon, Buddy candy (2) 1–4 days
5/8 Catch a Ditto, 20 Great Throws, 10 Ghost-type 2–14 days (Ditto hunt)
6/8 Reach Level 25, Battle in 10 Raids, Evolve Magikarp 1–2 weeks
7/8 Gold Kanto Medal (100 species), 50 Berry catches, Excellent Curveball 2–4 weeks
8/8 Catch Mew (guaranteed encounter) Instant

Total time: 2–4 weeks for active players. The hardest tasks are Ditto hunting and Gold Kanto Medal.

Stage 5: The Ditto Challenge

Catching Ditto is the hardest stage — it disguises as other Pokemon, and its spawn rate is low.

Current Ditto disguises (2025):

  • Gastly (most common)
  • Rattata
  • Pidgey
  • Zubat
  • Drowsing
  • Sentret
  • Hoothoot
  • Ledyba
  • Spinarak
  • Sentret

Pro Tip: Visit high-Pokemon-density areas (parking lots, downtown cores) during event hours — Ditto spawn rates increase during Community Days.

Stage 7: The Gold Kanto Medal

The Gold Kanto Medal requires registering 100 Kanto Pokemon to your PokeDex.

This is the longest task — you need to catch or trade for 100 different Kanto species. With Gen 9 Pokemon dominating spawns, Kanto Pokemon are increasingly rare.

Strategy Effectiveness
Event tickets (Kanto Tour-style) Instant — events spawn Kanto Pokemon
Trading Most efficient — trade for missing Kanto species
Evolution Evolve low-stage Pokemon (Pidgey → Pidgeotto, Rattata → Raticate)
Raids Kanto raids (Kabutops, Omastar, etc.)

Most players spend 2–4 weeks just on the Gold Kanto Medal.

Stage 6: The Magikarp Grind

Evolving Magikarp requires 400 candy — the same cost as Pidgey, but Magikarp candy is rarer (found in the wild, hatched from 2km eggs, or transferred from raids).

Candy Source Candy per Unit
Catch in wild 3
Transfer 1
Hatch from 2km egg 16 + 16 bonus (with Pinap)
Raid reward 50 (Magikarp raids)

400 candy / 3 per catch = 134 catches minimum. Use Pinap Berries to double candy from catches.

The Mew Encounter

After completing Stage 7, you face Mew in Stage 8:

Special Encounter Properties

Property Value
Catch Rate 100% (guaranteed)
Poke Balls Unlimited (infinite supply)
Flee Chance 0% (cannot flee)
Stats Predetermined (usually 10/10/10 IV minimum)
Level Trainer level (usually Level 15)
AR Photos Available — perfect for screenshots

The Mew encounter is a celebration — take your time and enjoy it.

Mew's Stats

Attribute Value
Type Psychic
Max CP 3,265 (Level 50)
Best Fast Move Shadow Claw
Best Charged Move Psychic
Unique Trait Can learn almost any move via TMs
Usage Great League, Ultra League, and raids

Weaknesses

Damage Type Multiplier
Bug 2x
Ghost 2x
Dark 2x

Mew's Psychic typing makes it vulnerable to Bug, Ghost, and Dark-types — common in PvP. It's situational in competitive play.

Shiny Mew Availability

Standard Quest: Non-Shiny Only

The Mew from A Mythical Discovery is always non-shiny. There's no way to get a shiny Mew from this quest.

Paid Event: Shiny Mew

Event Date Requirement
Pokemon GO Tour: Kanto February 2021 $11.99 ticket + quest completion
GO Fest 2022 Summer 2022 Ticketed special research

Shiny Mew is one of the rarest encounters in Pokemon GO — fewer than 100,000 exist worldwide.

Why No Free Shiny Mew?

Shiny Mew would devalue the standard quest — if players could get shiny Mew for free, the paid event model would collapse. By gating shiny Mew behind ticketed events, Niantic:

  1. Drives event ticket sales ($12–$25 per ticket)
  2. Creates exclusivity (only ticket holders get shiny)
  3. Maintains scarcity (fewer than 0.001% of trainers have shiny Mew)

Bottom Line: Mew's permanent story-lock makes it exclusive but accessible. The 8-stage quest is a time investment test — if you're willing to hunt Ditto and register 100 Kanto Pokemon, Mew is yours.

FAQ

Can I trade Mew to another account?

No — Mew is a Mythical Pokemon and cannot be traded. Every account must complete A Mythical Discovery independently.

How long does it take to get Mew?

2–4 weeks of active play. The longest tasks are Ditto hunting (Stage 5) and Gold Kanto Medal (Stage 7).

Can I use Lucky Eggs?

Yes — use Lucky Eggs during:

  • Stage 1: Catching 10 Pokemon (1,000 XP per catch with Lucky Egg)
  • Stage 4: Evolving 20 Pokemon (1,000 XP per evolve)
  • Stage 5: Catching Ditto (2,000 XP with Excellent Throw)

Is Mew good in PvP?

Mew is versatile — it can learn almost any move. However, its low Defense (145 at Level 50) and Psychic typing weaknesses make it situational in Great League and Ultra League.

Will Mew ever be available in raids?

Very unlikely — Mew is Mythical and Niantic has never offered it in raids. The only paths are Special Research (story quest) and paid events (shiny variant).
