Counter notes for Tentacool

  • Tentacool is a Water / Poison Pokémon with 70 base Speed and stronger special attack (50 Sp. Atk). Electric, Ground, and Psychic attacks all work offensively, but safer counters are usually the ones that reduce risk from its own STAB types.
  • Tentacool has several 2x weaknesses rather than a single 4x weakness, so the best counters are the ones that can hit it super-effectively while also reducing the risk from Water / Poison STAB.
  • Known abilities include Clear Body, Liquid Ooze, and Rain Dish. This page does not assume ability-specific battle effects, so verify the format before relying on a single counter.
  • Avoid counters that are weak to Water / Poison unless they are fast enough to pressure immediately or bulky enough to survive the exchange.
  • Tentacool does not need a separate alternate-form note for the standard National Dex matchup shown here.

What not to use

Fire×0.5Water×0.5Ice×0.5Fighting×0.5Poison×0.5Bug×0.5Steel×0.5Fairy×0.5

These attacking types are resisted or blocked by the defender's typing, so they are usually lower-priority choices unless they provide a special battle role.

Battle caveats

  • This ranking uses modern Gen 6+ type matchups, STAB value, defensive switch-in safety, and base stats.
  • Abilities, held items, Terastallization, weather, terrain, and format rules can change real battle outcomes.
  • Coverage moves can punish obvious counters, so treat this as type-based guidance rather than a full matchup simulator.
  • Move availability depends on game version and learnset data; this page recommends attacking types rather than guaranteed moves.
