How do dual-type Pokémon work with the type chart?

Dual-type Pokémon multiply effectiveness values from both types. If both types are weak to Ice, the Pokémon takes 4x damage. If one type resists and one is neutral, it takes 0.5x damage. If one type is immune, the immunity always wins regardless of the other type.

What type has the most resistances?

Steel has the most resistances with 10 types dealing reduced damage: Normal, Grass, Ice, Flying, Psychic, Bug, Rock, Dragon, Steel, and Fairy. Steel is also immune to Poison, making it the premier defensive type.

What is the strongest attacking type?

Ground hits 5 types super-effectively (Fire, Electric, Steel, Rock, Poison) — the most of any type. Fighting also hits 5 types SE. Ice hits only 4 but targets the most competitively common types (Dragon, Flying, Ground, Grass).

What type has no weaknesses?

Electric has only one weakness (Ground). Combining Electric with Flying (like Zapdos) creates a Ground immunity, effectively giving only Ice and Rock weaknesses. No single type has zero weaknesses, but some dual-type combinations come close.

Pokémon Type Chart Guide: All 18 Types Explained for Team Building

Q: How many Pokémon types are there?

There are 18 Pokémon types: Normal, Fire, Water, Grass, Electric, Ice, Fighting, Poison, Ground, Flying, Psychic, Bug, Rock, Ghost, Dragon, Dark, Steel, and Fairy. Each type has unique offensive and defensive matchups.

The Pokémon type chart is the foundation of every battle decision. Whether you’re picking moves, building teams, or predicting switches, understanding type effectiveness is what separates good players from great ones. This guide covers everything from basic matchups to advanced dual-type interactions. For the raw data, see the official type chart on Bulbapedia.

How Type Effectiveness Works

Every attack has a type. Every Pokémon has one or two types. When an attack hits, the game checks effectiveness:

Super effective (2×) — the attack type is strong against the defender’s type
Not very effective (0.5×) — the attack type is weak against the defender’s type
Immune (0×) — the defender’s type completely negates the attack
Neutral (1×) — normal damage, no bonus or penalty

Dual-Type Interactions

For dual-type Pokémon, multiply both type matchups together:

4× damage — both types are weak to the attack (Ice vs. Dragon/Ground Garchomp)
2× damage — one type is weak, one is neutral
1× damage — both neutral, or one weak + one resists (cancels out)
0.5× damage — one resists, one is neutral
0.25× damage — both types resist the attack
0× damage — one type is immune (immunity always wins, regardless of other type)

Example: A Ground move against Fire/Electric Rotom-Heat would be 2× × 2× = 4× damage — except Rotom’s Levitate ability grants Ground immunity, making it 0×.

Key Offensive Matchups for Team Building

The most valuable attacking types by number of super-effective hits:

Type	# Types Hit SE	Key Targets
Ground	5	Fire, Electric, Steel, Rock, Poison
Fighting	5	Normal, Ice, Rock, Dark, Steel
Ice	4	Dragon, Flying, Ground, Grass
Rock	4	Fire, Ice, Flying, Bug
Fire	4	Grass, Bug, Steel, Ice

Immunities: The Most Powerful Defensive Tool

Immunities mean zero damage regardless of the attacker’s power level — even a +6 boosted attack deals nothing:

Defending Type	Immune To	Why It Matters
Ghost	Normal, Fighting	Two common attacking types negated completely
Normal	Ghost	Blocks Shadow Ball and Shadow Claw
Ground	Electric	Volt Switch can’t pivot through you
Flying	Ground	Earthquake immunity is premium
Dark	Psychic	Safe switch into Psychic attackers
Fairy	Dragon	Draco Meteor and Outrage do nothing
Steel	Poison	Toxic and Sludge Bomb bounce off

Include at least 1-2 immunities on your team for free switch-in opportunities.

Using the Type Chart for Team Building

You don’t need to memorize all 324 matchup combinations. Focus on these practical applications:

Check shared weaknesses — use the Team Builder to find types that hit 3+ members super-effectively
Cover common types — can you hit Steel, Fairy, and Dragon SE? These are the most common defensive types in competitive
Include immunities — Ground immunity (Flying/Levitate) and Fighting immunity (Ghost) give free switches
Balance offensive types — don’t run 3 Water-types; diversify STAB types across your team
Respect dual-type math — 4× weaknesses are game-losing; avoid stacking them
