Marshadow, the Gloom Dweller Pokémon, stands as one of the most unique and sought-after Mythical entities in the Pokémon GO universe. As a dual Fighting and Ghost-type Pokémon originally discovered in the Alola region, it possesses a typing that provides unparalleled offensive coverage. Whether you are a dedicated PvP combatant in the Master League or a collector looking to complete your Alolan Pokédex, understanding how to secure this spectral fighter and optimize its performance is essential.

To obtain Marshadow, players must complete the "A Striking Shadow" Special Research, which became globally accessible following its initial debut at GO Fest 2024. This guide provides an exhaustive breakdown of how to navigate its research tasks, analyze its combat statistics, and deploy the most effective move combinations available in the current meta.

How to Get Marshadow in Pokémon GO via Special Research

Unlike standard wild spawns or Raid Bosses, Marshadow is a Mythical Pokémon that can only be obtained through a dedicated story-driven questline. As of the 2025 global release, the primary method for most trainers is the "A Striking Shadow" Special Research.

It is crucial to note that Marshadow is a one-time encounter per account. If you previously secured a Marshadow during the GO Fest 2024 events (Sendai, Madrid, or New York City), completing the "A Striking Shadow" research will reward you with Marshadow Candy and XL Candy instead of a second encounter.

A Striking Shadow Research Tasks and Rewards

The "A Striking Shadow" questline is divided into six distinct stages. Below is a detailed walkthrough to help you progress efficiently.

Step 1: The Foundation

  • Catch 50 Pokémon: Reward - 10 Razz Berries.
  • Spin 50 Pokéstops or Gyms: Reward - Mankey Encounter.
  • Explore 10 km: Reward - 20 Poké Balls. Stage Completion Rewards: 2,000 XP, Timburr Encounter, and 3 Golden Razz Berries.

Player Tip: To speed up the 10 km exploration, ensure Adventure Sync is enabled in your settings. This allows the game to track your steps even when the application is closed.

Step 2: Resource Management

Marshadow Type Advantages and Weaknesses

Marshadow’s typing is its greatest asset. As a Fighting/Ghost-type, it occupies a niche that allows it to resist some of the most common offensive types while hitting a broad range of enemies for neutral or super-effective damage.

Defensive Profile

Marshadow takes significantly reduced damage from the following types:

  • Normal: (Double Resistance - 39.1% damage)
  • Fighting: (39.1% damage)
  • Bug: (39.1% damage)
  • Poison: (62.5% damage)
  • Rock: (62.5% damage)

Its immunity-like resistance to Normal and Fighting moves makes it a premier counter to "Safe Swaps" like Snorlax, Slaking, or Vigoroth in various PvP formats.

Vulnerabilities

Despite its defensive utility, Marshadow must be wary of four primary weaknesses:

  • Flying: (160% damage)
  • Ghost: (160% damage)
  • Psychic: (160% damage)
  • Fairy: (160% damage)

In the Master League, this makes Marshadow particularly vulnerable to Mewtwo (Psychic), Zacian (Fairy), and Lugia (Flying).

What is the Best Moveset for Marshadow in Pokémon GO?

To maximize Marshadow's potential, you must choose moves that leverage its high Attack stat (265) and its Same Type Attack Bonus (STAB). Based on extensive testing in both Raids and the GO Battle League, here are the optimal configurations.

Best PVE Moveset (Raids and Gyms)

For attacking Raid Bosses, your goal is the highest Damage Per Second (DPS).

  • Fast Move: Counter
  • Charged Move: Close Combat

Counter is widely regarded as the best Fast Move in the game due to its high damage output and excellent energy generation. Combined with Close Combat, Marshadow can melt Steel, Rock, and Ice-type Raid Bosses. However, be mindful that Close Combat triggers a self-defense debuff in PvP, though this is less relevant in PvE where dodging is possible.

Best PVP Moveset (GO Battle League)

In PvP, versatility and energy management are key.

  • Fast Move: Counter or Shadow Claw
  • Charged Move 1: Close Combat
  • Charged Move 2: Rock Slide or Ice Punch

In March 2026, the addition of Shadow Claw gave Marshadow a powerful Ghost-type fast move option. While Counter is better for raw damage against Steel-types like Dialga, Shadow Claw allows Marshadow to win the mirror match and pressure Psychic-types more effectively.

Rock Slide is the preferred secondary charged move as it provides vital coverage against Flying-types (one of Marshadow’s biggest weaknesses). Alternatively, Ice Punch can be used to bait shields and threaten Dragon-types like Garchomp or Dragonite.

Marshadow Stats and Combat Power

Marshadow is not just a "Pokedex filler"; it possesses the stats to compete at the highest levels of the game.

Stat Value
Max CP (Level 50) 4217
Attack 265
Defense 190
Stamina 207

With a maximum CP exceeding 4200, Marshadow is a heavyweight in the Master League. Its Attack stat is comparable to top-tier legendary attackers, though its Defense is somewhat modest, meaning it relies on its unique typing and shield pressure to survive prolonged engagements.

Catching CP Ranges

When encountering Marshadow through the "A Striking Shadow" research (Level 15), the CP range is:

  • 1533 – 1599 CP

If Marshadow were ever to appear in Raids (Level 20):

  • 2044 – 2131 CP
  • 2555 – 2664 CP (Weather Boosted: Cloudy or Fog)

Is Marshadow Good in the Meta?

Raid Performance

Marshadow is an A-Tier Fighting attacker. While it may not consistently surpass Mega Lucario or Terrakion in terms of raw DPS, its Ghost typing gives it a durability advantage against bosses that use Psychic or Fighting moves. It is an excellent addition to a secondary Fighting-type team.

PvP Master League Analysis

Marshadow truly shines in the Master League. Its ability to delete Dialga (with Counter/Close Combat) while simultaneously scaring away Giratina (with Shadow Claw/Ice Punch) makes it a "Core Breaker." In our testing, Marshadow functions best as a Closer or a Lead. If you can save a shield for Marshadow, its ability to land a massive Close Combat can flip almost any match.

In the Ultra League, Marshadow is also viable, though it requires heavy investment to reach the 2500 CP cap. Its performance here is rated as S-Tier by many analysts because of its ability to wall Registeel and Cobalion.

How to Counter Marshadow in Battles

If you face Marshadow in the GO Battle League or a simulated environment, you need specific counters to exploit its weaknesses.

  1. Mewtwo: Using Psycho Cut and Psystrike. Mewtwo outpaces Marshadow in energy generation and hits its Psychic weakness for massive damage.
  2. Togekiss: Using Charm. The high Fairy-type fast move damage will shred Marshadow before it can even reach a charged move.
  3. Rayquaza: Using Air Slash and Dragon Ascent. The Flying-type damage is catastrophic for Marshadow.
  4. Giratina (Origin Forme): Using Shadow Claw and Shadow Ball. As a fellow Ghost-type, Giratina has the bulk to outlast Marshadow in a slugfest.

Frequently Asked Questions about Marshadow

Summary of Marshadow’s Role in Pokémon GO

Marshadow is a definitive powerhouse that bridges the gap between the ghostly unknown and the raw power of fighting styles. By completing the "A Striking Shadow" Special Research, players gain access to a versatile fighter capable of dismantling Steel-type walls and surprising opponents with its spectral agility.

To get the most out of your Marshadow, focus on:

  • Completing the research stages involving Shadow Raids and Excellent Throws promptly.
  • Prioritizing Counter and Close Combat for general use, while considering Shadow Claw for specialized PvP teams.
  • Using Rock Slide as a secondary move to cover its Flying-type vulnerability.
  • Investing your Rare Candies to reach its Level 50 potential of 4217 CP.

Whether it is lurking in the shadows of a Master League battle or leading the charge against a Raid Boss, Marshadow is a premier investment for any serious Pokémon GO trainer.
