Fire-type weakness
Fire-type defenders take ×1.6 from Water, Ground, Rock — those are the moves you bring when a Fire raid boss or Fire-type gym defender is in front of you. Below is the full chart of what hits Fire hard, what resists Fire, the inverse (where Fire attacks shine and where they fall flat), dual-type matchups for the most common Fire-pair defenders in the game, and the top 5 attackers per super-effective type pulled from the live tier list.
Single-type Fire defenders take ×1.6 from any move of the listed weak-to types. Dual-type Fire defenders stack multiplicatively — a second weakness from their partner type can push the multiplier all the way to ×2.56. Resisted attacks deal only ×0.625, and doubly resisted attacks (a stack of two ×0.625) drop damage to roughly ×0.39 — never bring those into a Fire fight.
Use Fire attackers when the boss in front of you is one of the listed types. Stack STAB (×1.2) on top by picking a Fire-type mons that knows a Fire fast and Fire charged move. The combined multiplier is ×1.92 before weather.
Avoid Fire attackers when the defender is one of the listed types. Resisted damage cuts your DPS by 37.5%; doubly-resisted damage cuts it by 61%. In raids this is the difference between a 3-account clear and a relobby.
Most Fire-type bosses in the game are dual-type. Combined effectiveness multiplies through both types, so a Fire/X defender may be ×2.56 weak to a single attacker type, or fully neutral if the partner type cancels the Fire weakness. Pick the attacker type that maxes the multiplier.
| Dual-type | Examples | Top weakness | Mult |
|---|---|---|---|
| Fire / Flying | Charizard, Moltres, Ho-Oh | Rock | ×2.56 |
| Fire / Fighting | Blaziken, Infernape, Emboar | Water | ×1.60 |
| Fire / Ground | Camerupt, Groudon | Water | ×2.56 |
| Fire / Rock | Magcargo | Water | ×2.56 |
| Fire / Dark | Houndoom, Incineroar | Water | ×1.60 |
| Fire / Steel | Heatran | Ground | ×2.56 |
| Fire / Ghost | Chandelure | Water | ×1.60 |
| Fire / Psychic | Delphox | Water | ×1.60 |
Leagues: Master, raid attacker meta.
Charizard-X / Reshiram in Master; Mega Charizard Y / Reshiram top raid attackers.
Knowing the Fire weakness chart matters as much in PvP as in raids — a Fire lead into one of the listed weak-to types loses the matchup before shields even come into play. Always check the dual-typing of the opposing lead: a single Fire mons is harder to counter than a Fire/Y where Y stacks a second weakness.
›What is Fire-type weak to in the game?
Fire-type defenders take ×1.6 damage from Water, Ground, Rock attacks. Bring an attacker of one of those types to break a Fire raid boss or gym defender fastest.
›What resists Fire-type attacks?
Fire attacks are resisted by Fire, Water, Rock, Dragon (×0.625 damage). Avoid sending Fire attackers into those defenders.
›What is super-effective against Fire?
Fire attacks deal ×1.6 to Grass, Ice, Bug, Steel. Use Fire attackers to clear those defenders quickly in raids.
›Which Fire-type mons are best in PvP?
Charizard-X / Reshiram in Master; Mega Charizard Y / Reshiram top raid attackers. League fit: Master, raid attacker meta.
›How do dual-type Fire defenders compute damage?
The matrix is multiplicative. If a Fire/Y dual-type has two weaknesses to the attacking type (one from Fire, one from Y), the multiplier stacks to ×2.56 — the maximum without STAB / weather.
