Quick summary
Overview
Gigantamax Grimmsnarl is a terrifying force in Pokémon GO raids, embodying both elegance and chaos. With its hair-like muscles and demonic posture, this Dark/Fairy-type Pokémon dominates battles with its Gigantamax energy, capable of unleashing powerful Max Starfall and Max Darkness attacks.
Its combination of Dark and Fairy typing gives it limited but exploitable weaknesses — primarily Fairy, Poison, and Steel attacks. A well-coordinated team can bring it down quickly if you focus on exploiting these vulnerabilities.

Moves & Threats
Grimmsnarl common fast moves are Bite or Sucker Punch or Low Kick. Charged moves include Dark Pulse or Play Rough or Foul Play and Power-Up Punch. G-Max Snooze not only delivers heavy damage but also leaves a damaging area for a short time — timing your swaps and using at least one bulky support reduces wipe risk.
Weather Effects
Foggy weather : boosts Dark moves. Cloudy weather : boosts Fairy and Fighting attackers. Snowy weather : boosts Steel moves. Sunny weather : boosts Poison attackers.
Size
Recommended: 15–20 trainers for comfortable clears with mixed player levels. With many Gigantamax / Dynamax counters, 10–14 can work. Under 8 trainers should be attempted only if all participants are high-level and coordinated with ideal counters and Dynamax/G-Max boosts.
Rewards
Reasons include Pokédex entry, strong Dark / Fairy attacker, shiny chance, and XL Candy farming.
Raid Strategy & Catch Tips
Steel-types perform excellently, resisting Grimmsnarl’s Fairy and Dark attacks while dealing super-effective damage. Poison-types also work well.
