Internal score from immunities, resistances, weaknesses, and 4× pressure.
Profile
fragile defensive profile
Main Planning Risk
Protect the Fighting 4× weakness before relying on this pairing as a switch-in.
How to interpret this pairing
Rock/Dark should be judged by the trade it creates, not by the raw number of weaknesses alone. It offers safe entry into Psychic, Normal, Fire, Poison, Flying, Ghost, which means it can buy turns when those attack types are predictable. In exchange, the opponent will usually try to line upFighting, Water, Grass, Ground, Bug, Steel, Fairy, 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 Fire for Grass, Bug, Steel, Fairy; Poison for Fighting, Grass, Bug, Fairy; Flying for Fighting, Grass, Ground, Bug; Steel for Grass, Bug, Steel, Fairy; Grass for Water, Grass, Ground. 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 Fighting, Water problem.
