✓ Main Resistances:

½× resists Fire, Water, Ice, Fighting, Poison, Bug, Steel, Fairy

Water/Poison strategy: Fairy control with three direct weaknesses

Water/Poison and Poison/Water are the same defensive pairing; this page uses water-poison as the canonical URL. Water/Poison is a defensive utility pairing that checks Fairy, Fire, Water, Ice, Fighting, Poison, Bug, and Steel lanes. Representative Pokémon include Tentacool, Tentacruel, Qwilfish, Mareanie, Toxapex. The standard type chart gives this combination no 4× weakness and 2× weak to Electric, Ground, Psychic. It has no type immunity under the standard chart. Its main defensive value comes from no ¼× resistance; ½× resists Fire, Water, Ice, Fighting, Poison, Bug, Steel, Fairy, but stats, ability, item, and format still decide whether a real Pokémon can use those entries repeatedly.

Offensive plan

Water STAB threatens Fire, Ground, and Rock targets, while Poison STAB pressures Fairy and Grass targets. Electric, Ground, and Psychic are the chart weaknesses, so the user must respect common special coverage and Earthquake-style pressure. The typing is especially useful on bulky utility Pokemon that can recover, spread status, or set hazards.

Counterplay and defensive risks

To counter Water/Poison, start with the chart pressure: Electric, Ground, Psychic. If a 4× weakness is listed, preserve that attack type before revealing it; if there is no 4× weakness, repeated 2× pressure and hazard chip usually matter more than a single surprise hit. Scout for abilities, Terastallization, weather, recovery, and pivot moves before assuming the visible multiplier ends the exchange.

Team-building advice

Water/Poison needs Electric, Ground, and Psychic answers. Grass, Ground-immune, Dark, and Steel partners can cover those lanes while Water/Poison absorbs Fairy and Water pressure. Use the Team Calculator to check whether the rest of the six stacks the same Electric, Ground problem, then compare the full defensive chart before choosing moves or teammates.

Main Planning Risk

No 4× weakness, but repeated Electric, Ground, Psychic pressure can still force predictable switches.

How to interpret this pairing

Water/Poison should be judged by the trade it creates, not by the raw number of weaknesses alone. It offers safe entry into Fire, Water, Ice, Fighting, Poison, Bug, which means it can buy turns when those attack types are predictable. In exchange, the opponent will usually try to line upElectric, Ground, Psychic, so the pairing needs either speed, bulk, recovery, pivoting, or a teammate ready to absorb that pressure.

Team-building partners

Based on TypeMatchup's own defensive coverage pass, useful single-type partners to test first are Grass for Electric, Ground; Electric for Electric; Ground for Electric; Flying for Ground; Psychic for Psychic. These are not automatic best teammates; they are a shortlist for reducing repeated weaknesses before you choose actual Pokémon, moves, items, abilities, and battle format.

When this combination is worth using

Use this combination when its resisted or immune entries match threats you expect to face repeatedly. Avoid using it only because the summary looks efficient: a 4× weakness can dominate a matchup, while even a strong resistance profile can fail if the Pokémon lacks recovery, speed control, or meaningful pressure after switching in. For a six-Pokémon build, run this pairing through the Team Calculator and check whether another teammate shares the same Electric, Ground problem.
