Impidimp is a dual-type Dark/Fairy Pokémon that first appeared in the Galar region of Generation VIII. Known for its mischievous nature and unique typing, this Pokémon is a staple for many trainers looking to build a supportive or disruptive team. Understanding the Impidimp evolution line is essential for anyone playing Pokémon Sword and Shield, Pokémon Scarlet and Violet, or Pokémon GO.

Impidimp evolves into Morgrem starting at level 32. Morgrem then evolves into Grimmsnarl starting at level 42. In the mobile game Pokémon GO, the process differs slightly, requiring 25 Impidimp Candies for the first evolution and 100 Candies for the second.

The Complete Impidimp Evolution Line

The Impidimp family consists of three distinct stages, each retaining the Dark and Fairy typing. This specific combination was a series first, providing a fascinating set of resistances and immunities that make the final stage particularly dangerous in competitive play.

First Stage: Impidimp

Impidimp is the base form, categorized as the Wily Pokémon. It is a small, purple creature that thrives on negative energy. In terms of gameplay, Impidimp is relatively frail, with base stats totaling 265. Its primary purpose in the early game is to utilize its Prankster ability to disrupt opponents with status moves before they can react.

Second Stage: Morgrem

Once Impidimp reaches level 32, it undergoes its first transformation into Morgrem. Morgrem stands taller and develops more prominent hair-like appendages that it uses like spears to attack. Its base stat total increases to 370, with a notable jump in both Attack and Special Attack. Morgrem serves as a transitional phase, often used in middle-game playthroughs before reaching the final level threshold.

Final Stage: Grimmsnarl

At level 42, Morgrem evolves into Grimmsnarl, the Bulk Up Pokémon. Grimmsnarl is a powerhouse characterized by its massive frame covered in hair that acts like muscle fibers. With a base stat total of 510 and access to a Gigantamax form in the Galar region, Grimmsnarl is one of the most versatile support Pokémon in the history of the franchise.

Evolution Methods Across Different Games

While the level requirements are consistent across the main series titles, the environment and methods to facilitate this evolution vary depending on the game you are playing.

Pokémon Scarlet and Violet (Paldea Region)

In the Paldea region, trainers can find Impidimp primarily in the Tagtree Thicket. To evolve it quickly:

  • Level 32: Reach this level through traditional battling or by using EXP Candies (S, M, or L) obtained from Tera Raid Battles.
  • Level 42: Continue leveling up or use Rare Candies to trigger the final evolution into Grimmsnarl immediately.

The open-world nature of Scarlet and Violet makes it easier to encounter Impidimp early in the game if you head toward the northern parts of the map after completing the initial tutorial.

Pokémon Sword and Shield (Galar Region)

Galar is the home region of this evolutionary line. Impidimp is most commonly found in the Glimwood Tangle, a luminous forest between Stow-on-Side and Ballonlea.

  • Leveling Strategy: Since Glimwood Tangle features Pokémon around the level 30 range, a newly caught Impidimp will often be just one or two levels away from its first evolution into Morgrem.
  • Gigantamax Factor: Unlike the Paldea versions, certain Grimmsnarl caught in Max Raid Battles in the Wild Area (specifically the Dusty Bowl) possess the Gigantamax Factor, allowing them to transform into a towering form with the unique G-Max Move, G-Max Snooze.

Pokémon GO

Evolution in the mobile environment does not rely on levels. Instead, it is fueled by Candy collected through catching, hatching, or transferring the same species.

  • Impidimp to Morgrem: 25 Candies.
  • Morgrem to Grimmsnarl: 100 Candies.

Because Impidimp is a 100% male species, you do not need to worry about gender-specific evolution items or requirements like those found with Kirlia or Snorunt.

Statistical Analysis of the Evolution

The jump in power between the three stages is significant, particularly in physical bulk and offensive pressure.

Stat Impidimp Morgrem Grimmsnarl
HP 45 65 95
Attack 45 60 120
Defense 30 45 65
Sp. Atk 55 75 95
Sp. Def 40 55 75
Speed 50 70 60
Total 265 370 510

One interesting observation in the statistics is the Speed drop when Morgrem evolves into Grimmsnarl (dropping from 70 to 60). This trade-off is compensated by a massive increase in HP and Attack, moving the Pokémon from a glass-cannon disrupter to a bulky utility attacker.

Why the Prankster Ability Changes Everything

The most compelling reason to evolve Impidimp is to gain access to the Prankster ability on a fully evolved Pokémon with decent bulk. Prankster gives +1 priority to all status moves. For Grimmsnarl, this includes:

  • Reflect and Light Screen: Setting up dual screens before the opponent can move, effectively doubling your team's durability.
  • Thunder Wave: Instantly paralyzing fast threats.
  • Taunt: Shutting down opposing support Pokémon.
  • Parting Shot: Lowering an opponent's stats and switching out safely.

In our testing within the Master Ball tier of ranked battles, a Prankster Grimmsnarl often dictates the pace of the entire match. Even against faster legendary Pokémon, the ability to set a priority screen ensures that your offensive teammates can survive hits they otherwise wouldn't.

Best Natures and Held Items for Evolution

When you begin the journey of evolving your Impidimp, choosing the right Nature will save you from using expensive Mints later.

Recommended Natures

  1. Careful (+Sp. Def, -Sp. Atk): This is the gold standard for support Grimmsnarl. It maximizes its special bulk, allowing it to survive powerful Fairy or Steel-type special attacks while it sets up screens.
  2. Adamant (+Attack, -Sp. Atk): Use this if you want a more offensive Grimmsnarl that utilizes moves like Play Rough or Spirit Break to deal significant damage.
  3. Impish (+Defense, -Sp. Atk): Good for balancing out its physical defense, though generally less popular than Careful.

Best Held Items

  • Light Clay: This is the essential item for the Impidimp line. It extends the duration of Reflect and Light Screen from five turns to eight turns.
  • Lagging Tail: Often used with the move Trick. Because of Prankster, you can use Trick with priority to give the opponent the Lagging Tail, forcing them to move last regardless of their Speed stat.

Where to Find Impidimp in Pokémon Scarlet and Violet

If you are just starting your journey in Paldea, knowing exactly where to find the "Wily Pokémon" can be tricky.

Tagtree Thicket (Main Habitat)

Impidimp is a very common spawn in the Tagtree Thicket, located in the East Province. They often hide near the painted trees. If you are having trouble finding one, eating a sandwich with Encounter Power: Fairy or Encounter Power: Dark will make them appear in abundance.

Kitakami (The Teal Mask DLC)

For those with the expansion pass, Impidimp can be found in the Kitakami Wilds and the Timeless Woods. These areas offer higher-level wild spawns, often allowing you to catch a Morgrem directly, skipping the first evolution level requirement.

Understanding the Dark/Fairy Typing

The evolution of Impidimp maintains a typing that is defensively and offensively unique.

  • Immunities: Dragon and Psychic. This is a massive advantage. Grimmsnarl can switch into a "Draco Meteor" or a "Psychic" with zero damage taken, forcing the opponent to lose momentum.
  • Resistances: Ghost and a quadruple resistance to Dark.
  • Weaknesses: Poison, Steel, and Fairy.

In the current meta, the Steel weakness is the most dangerous due to the prevalence of moves like "Make It Rain" or "Iron Head." When using the Impidimp line, it is often wise to pair them with a Fire or Ground-type teammate to cover these vulnerabilities.

How to Level Up Impidimp Fast

If you have a level 1 Impidimp and want a Grimmsnarl as quickly as possible, follow these steps:

  1. Tera Raid Rewards: Farm 5-star and 6-star raids to accumulate EXP Candy XL. Using just a few of these will instantly catapult an Impidimp to level 42.
  2. Lucky Egg: Give your Impidimp a Lucky Egg to hold. This increases the experience gained from battles by 50%.
  3. Meal Powers: Visit a restaurant in Mesagoza or make a sandwich with Exp. Point Power: Fairy. This increases the experience gained specifically for Fairy-type Pokémon.
  4. Chansey/Blissey Farming: In Scarlet and Violet, head to the area near the Team Star Fighting Crew base. Chansey spawns frequently here and provides the highest experience yield in the game.

Common Questions About Impidimp Evolution

What level does Impidimp evolve?

Impidimp evolves into Morgrem at level 32. Morgrem evolves into Grimmsnarl at level 42.

Does Impidimp need an item to evolve?

No. Unlike Pokémon that require stones or trading, the Impidimp line evolves purely through leveling up in the main series games.

Can Impidimp be female?

No. Impidimp, Morgrem, and Grimmsnarl are an exclusively male species. If you are looking for a female counterpart, there isn't one in this specific evolutionary line, though the Hattrem line serves as a thematic female-only parallel (Psychic/Fairy).

Is Morgrem better than Grimmsnarl?

In almost all scenarios, Grimmsnarl is superior due to its significantly higher base stats. However, some players use Morgrem with the item Eviolite (which boosts the Defense and Special Defense of unevolved Pokémon). While this makes Morgrem remarkably tanky, it generally lacks the utility and HP pool that makes Grimmsnarl a top-tier threat.

The Role of Negative Emotions in Lore

One of the most fascinating aspects of evolving Impidimp is seeing how its behavior changes in the Pokédex entries. Impidimp is described as a nuisance that sneaks into homes to steal items, feeding on the frustration of humans. It sucks in negative energy through its nose.

As it evolves into Morgrem and then Grimmsnarl, this prankster attitude shifts toward a more predatory and defensive stance. Grimmsnarl uses its hair to wrap around its limbs, enhancing its physical strength to the point where it can overpower even the strongest Machamp. This transition from a "wily" thief to a "bulky" bruiser is reflected perfectly in its stat distribution.

Strategic Movepools for Evolution Stages

When training your Impidimp toward its final form, keep an eye out for these key moves:

  • Fake Out (Learned as Impidimp): Essential for double battles to flinch an opponent on the first turn.
  • Spirit Break (Learned as Grimmsnarl): A signature move that deals damage and guaranteed lowers the opponent's Special Attack. This makes it much harder for special attackers to break through your screens.
  • Sucker Punch: Provides much-needed priority damage, allowing Grimmsnarl to pick off weakened foes despite its low Speed.

Summary

The Impidimp evolution journey is a rewarding path for any trainer. By reaching level 32 and level 42, you transform a small, mischievous prankster into Grimmsnarl, one of the most powerful support assets in the modern Pokémon era. Whether you are navigating the foggy woods of Galar or the vast plains of Paldea, ensuring you have a high-level Grimmsnarl with the Prankster ability will significantly enhance your team's tactical depth. Remember to focus on HP and defensive stats during training, and always utilize the unique Dark/Fairy typing to shut down Dragon and Psychic threats.

Evolution is more than just a stat boost for this line; it is a complete shift in tactical utility. From the annoying pranks of a level 1 Impidimp to the game-changing screen-setting of a level 42 Grimmsnarl, this Pokémon remains a fan favorite for its design, its lore, and its undisputed effectiveness on the battlefield.
