Is Grimer Good?

Grimer is strictly an early-game playthrough Pokémon and entirely unviable for competitive PvP. While its high HP and decent physical damage output make it usable for the main story in Scarlet and Violet, its abysmal Speed guarantees it takes heavy damage before moving, making it a liability late-game.

Grimer is a temporary team member that relies on Poison Touch to chip away at early-game NPCs, but requires evolution to stay relevant.

Rating 3/10 · Tier D-(In-Game), Unranked (PvP) · Role : Early-Game Physical Bruiser

Strengths

• High base HP allows it to absorb early-game neutral attacks.
• Poison Touch ability provides free passive damage on contact moves.
• Access to a decent physical movepool via TMs.

Weaknesses

• Abysmal Speed guarantees it will almost always take a hit before attacking.
• Requires reaching level 38 to evolve, which is far too late for its unevolved stats.
• Zero viability in any serious competitive format.
• Extremely vulnerable to common Ground-type coverage moves like Earthquake.

Grimer belongs firmly in the lower tiers of in-game playthroughs and remains entirely unranked in serious competitive formats. If you are looking for a Pokémon to climb the ranked ladder in Scarlet and Violet, look elsewhere. Grimer simply lacks the stats to survive in a meta dominated by fast, hard-hitting threats.

During a standard playthrough, Grimer functions as an early-game physical bruiser. You send it out against neutral matchups, let its high HP absorb a hit, and retaliate with a physical attack. Because its Speed is practically non-existent, you are forced to play reactively in every single turn.

Its role is highly temporary. Without the Eviolite item to artificially boost its defenses, Grimer becomes a massive liability around the mid-game mark. You will spend most of your time babying it until it finally evolves at level 38.

If you insist on using Grimer for your story team, your first priority is securing the Poison Touch ability. This is the only trait that gives Grimer a unique edge, offering a high chance to poison the target whenever Grimer uses a contact move. Avoid Stench and Sticky Hold, as they offer zero offensive pressure in a playthrough.

For its moveset, you want to focus entirely on physical attacks to leverage its only decent offensive stat. Early on, you will rely on whatever physical moves you can find. Once you gain access to TMs, upgrade its arsenal immediately.

• Poison Jab: The absolute core of its kit. It benefits from Same Type Attack Bonus (STAB) and triggers Poison Touch.
• Crunch: Essential Dark-type coverage to hit the Psychic-types that threaten it.
• Ice Punch / Fire Punch: Excellent elemental coverage if you can afford the TMs, allowing Grimer to hit Ground and Steel-types respectively.

Item-wise, the Eviolite is non-negotiable if you plan to keep Grimer unevolved past level 25. Without Eviolite, its raw HP is not enough to compensate for its low defensive stats against mid-game gym leaders.

Adapting to Paldea's Mechanics

In Pokémon Scarlet and Violet, Terastallization offers Grimer a slight lifeline during the story. Tera Dark is highly recommended for playthroughs, as it completely flips its fatal Psychic weakness into an immunity, allowing you to bait and punish Psychic-type NPCs. Alternatively, Tera Flying provides an immunity to devastating Ground-type attacks like Earthquake.

Despite these Tera options, Grimer's fundamental flaw remains unchanged: it is too slow. In the open-world format of Paldea, you can easily accidentally wander into areas where wild Pokémon out-level and out-speed Grimer, resulting in quick knockouts.

Looking Ahead to Legends: Z-A

With Pokémon Legends: Z-A set entirely within Lumiose City, urban Pokémon like Grimer are highly likely to make an appearance. While the specific battle mechanics of Legends Z-A are still under wraps, Grimer's historical performance dictates it will remain a slow, bulky status-inflicter.

If the Agile/Strong style mechanics from Legends: Arceus return, Grimer will suffer immensely. Slow Pokémon in that system often face double turns from faster opponents, which would make Grimer nearly unusable without heavy defensive investment.

Grimer finds its niche against specific story obstacles where its Poison typing shines defensively. It easily walls early-game Grass-type and Bug-type Pokémon, turning their weak attacks into setup opportunities. If you are facing the Grass Gym in Paldea, Grimer can comfortably sit on the field and absorb hits.

Fairy-type matchups are another area where Grimer performs adequately. Since Fairy-types rarely carry Ground or Psychic coverage early on, Grimer can force its way through them using Poison Jab.

Furthermore, Grimer excels against physical attackers that rely on multi-hit moves. Thanks to Poison Touch, every single strike of a move like Fury Swipes or Bullet Seed has an independent chance to poison the attacker, heavily punishing NPCs for touching it.

Grimer's most glaring weakness is its abysmal Speed. In Pokémon, moving last means you take damage before you can execute your strategy. As you progress through the game, enemy NPCs start hitting harder, and Grimer's HP pool simply cannot keep up with the constant chip damage it takes every single turn.

Ground-type moves are another fatal flaw. Earthquake is one of the most common coverage moves in the franchise, distributed widely among physical attackers. A single Earthquake from a mid-game boss will instantly remove an unevolved Grimer from the field.

Finally, its evolution level is a massive hurdle. Level 38 is incredibly steep for a Pokémon with unevolved base stats. By the time you reach the late 30s in Scarlet and Violet, you are facing fully evolved boss teams, leaving Grimer severely outmatched until it finally becomes Muk.

Do not bring Grimer into Tera Raid battles. Tera Raids require high immediate damage or specialized support kits, neither of which Grimer possesses. Its low speed and mediocre bulk will cause it to faint repeatedly, draining your raid timer and frustrating your teammates.

You should also avoid Grimer entirely if you are building a team for ranked PvP. It lacks the stats, the priority moves, and the utility to survive against meta threats. It is strictly a casual playthrough companion.

Superior Alternatives

• Paldean Wooper / Clodsire: Available incredibly early in Scarlet/Violet. Clodsire offers a vastly superior Poison/Ground typing, the Water Absorb ability, and incredible special bulk. It completely outclasses Grimer as a bulky Poison-type.
• Glimmet / Glimmora: If you want a Poison-type that actually applies offensive pressure and sets hazards, Glimmora is a top-tier choice that transitions perfectly from late-game story to competitive play.
• Toxtricity: Offers a much faster, harder-hitting special attacking profile with a great Poison/Electric typing.
