Cloyster is a Water/Ice type in Pokémon GO, so it’s weak to Electric, Grass, Fighting, and Rock moves.

Quick Scoop: What Beats Cloyster in Pokémon GO?

Think of Cloyster as a super‑tanky shell with big Ice damage, but predictable weaknesses. To reliably beat it, you want fast, super‑effective damage from one of its four weak types.

Cloyster’s Type and Weaknesses

  • Type: Water + Ice.
  • Weak to:
    • Electric
    • Grass
    • Fighting
    • Rock
  • Typical role: Decent defender / raid boss with high Defense but low HP and mediocre Attack.

In practice, that means strong offensive picks from those four types will usually melt it before it can spam Ice moves.

Best Counter Types (and Why)

  1. Electric attackers
    • Hit Cloyster super‑effectively and ignore Water resistance issues.
 * Great for raids and gyms where you want quick clears.
  1. Grass attackers
    • Double‑up nicely vs its Water side and are widely available.
 * Just watch out: Grass often takes heavy damage from Ice moves in Trainer Battles.
  1. Fighting attackers
    • Exploit its weakness and can chunk it down quickly in raids and PvP.
 * Some Fighting types also resist Ice or Water, letting them stay in longer. Community discussions mention Poliwrath with Fighting moves as a solid answer because it can resist Cloyster’s usual coverage.
  1. Rock attackers
    • Rock hits Ice super‑effectively and brings strong fast moves.
 * Good choice if you also want something that doubles as a general raid/Gym attacker.

Example Pokémon That Beat Cloyster

Here’s a simple view of common counters that fit those types (exact “best” counters can vary by movesets and league, but these archetypes stay strong):

[3][5][9] [5][9] [7][5] [7][5] [9][5] [5][9]
Role Type Focus Example Counters (conceptual) Why They Work
Fast raid clears Electric High‑DPS Electric attackers with strong charge moves Exploit Electric weakness, shred Cloyster’s low HP despite its Defense.
General gym offense Fighting / Grass Bulky Fighters or Grass types that can tank a charged Ice move. Hit super‑effectively while surviving Cloyster’s damage output.
Flexible raid teams Rock Strong Rock attackers used in other raids as well. Capitalize on Cloyster’s Ice weakness with reusable raid staples.
_Illustrative example_ : in a Tier 3 Cloyster raid, stacking Electric or Fighting attackers that exploit these weaknesses is a recommended strategy in raid guides. Community posts also highlight Fighting‑type Pokémon like Poliwrath as particularly comfortable counters thanks to resistances and super‑effective moves.

Mini Strategy Tips

  • In raids:
    • Prioritize Electric, Fighting, Grass, or Rock attackers with their strongest same‑type fast + charged moves.
* Dodging big Ice charge moves can help squishier Grass types stay alive.
  • In PvP / Great League:
    • Treat Cloyster as a niche, high‑Defense Water/Ice that hates being farmed by Electric and Fighting types.
* Bring at least one of those types if your local meta uses Cloyster as an anti‑Flyer / anti‑Dragon pick.

TL;DR

  • What beats Cloyster in Pokémon GO?
    • Anything with Electric, Grass, Fighting, or Rock damage and decent bulk or DPS.
  • If you walk into a raid or gym with a squad built from those four types, Cloyster’s shell won’t last long.
