Types (Japanese: タイプ Type) are properties for Pokémon and their moves. Each type has three properties: which types of Pokémon it is super effective against, which types of Pokémon it is not very effective against, and which types of Pokémon it is completely ineffective against. There are 18 types, each of which is listed to the right. During Generation I, types were occasionally referred to as elements.

A Pokémon may have either one or two types. For instance, Charmander is a Fire type, while Bulbasaur is both a Grass type and a Poison type. With the current 18-type system, there are 324 possible ways to assign types to Pokémon, with 171 unique combinations. As of Generation VI, 131 different type combinations have been used. Pokéstar Studios opponents can also have types.

All moves have only one assigned type. However, the moves Flying Press and Freeze-Dry have custom interactions with defending types that do not strictly match their assigned types.

Most Gym Leaders and members of the Elite Four are designed to have a type-specific theme.

Type effectiveness

If the type of a move used by a Pokémon is strong against the opponent's type, then the damage done is twice the normal amount. However, if a move's type is not very effective against the opponent's type, the damage done is half the normal amount.

For Pokémon that have two types, the overall damage is calculated against both types combined. This means that if a move's type is strong against both of the opponent's types (such as Dig, a Ground-type move, used against an Aggron, a Steel/Rock Pokémon), then the move does 4 times the damage. On the other hand, if a move's type is weak against both of the opponent's types (such as Wake-Up Slap, a Fighting-type move, used against a Sigilyph, a Psychic/Flying Pokémon), then the move does ¼ of the damage. Similarly, if the move is strong against one of the opponent's types but weak against the other (such as Razor Leaf, a Grass-type move, used against a Gyarados, a Water/Flying Pokémon), the move deals normal damage.

If a move's type is completely ineffective due to one of the opponent's types, then the move does zero damage, even if the opponent has a second type that would be vulnerable to it (as in Thunderbolt, an Electric-type move, used against a Quagsire, a Water/Ground Pokémon). Otherwise, before Generation V, a move will always do at least one HP of damage. In Generation V, it became possible to deal zero damage since certain damage modifiers (such as Reflect) are applied after the damage is ensured to be at least 1.

Type chart

A type chart shows which modifiers are applied to move types when attacking Pokémon of each type. Please note that this only covers single types, not pairs. To get a dual-type Pokémon's matchup against a specific move type, go across the table's columns to each of the types, see what the effectiveness of the move is against both, and multiply the effectiveness together: in this way a Flying-type move would hit for 4× damage on a Bug/Grass Pokémon, while a Ground-type move used against the same would do only a quarter of its normal damage. The type chart differs depending on the generation of games it is from.

Inverse Battles reverse this type chart, making immunities and resistances into weaknesses, and weaknesses into resistances.

Type-affected game mechanics

All games before Generation IV also made a distinction between physical and special moves based on their type. From Generation IV onward, this is dictated by the move itself.

When the type of an attack corresponds with one of the types of the Pokémon using it, the attack power will be increased by 50%. This type advantage is referred to as same-type attack bonus, or STAB for short. As an example, consider an Aron that knows Metal Claw and Cut. Both attacks are physical attacks and both have a base power of 50. However, because Aron is a Steel/Rock Pokémon, the power of its Metal Claw move will effectively be 75.

Some weather conditions, Abilities, and held items affect moves of a certain type. Sunny Day, for example, causes Fire-type moves to increase in power, while Levitate causes Ground-type moves to not work on the Pokémon with this Ability. Likewise, each type has a specific item that can be given to a Pokémon to hold that will power up one of the specific types, such as the Metal Coat, which powers up Steel-type moves by 20% (10% prior to Generation IV).

Some moves can change the type of a Pokémon. For example, Camouflage changes the user's type to a type corresponding to the battlefield terrain. Abilities can also change the type of a Pokémon. So far, the only such Abilities are Color Change, Multitype, and Protean.

??? type

Main article: ??? (type)

The ??? type is the only type to have been removed from the core series games. The ??? type only existed from Generation II to Generation IV, and was primarily used as the type of the move Curse. It was removed in Generation V, and Curse became a Ghost-type move.


While not generally regarded as a type, Shadow moves have their type listed as "------". Shadow Pokémon can be considered to be of this type, but they still retain their regular typing as well. In Pokémon XD, Shadow moves are not very effective against Shadow Pokémon and super effective against non-Shadow Pokémon.

Glitch types

Main article: List of glitch types

There are several glitch types, such as the Bird type, which only appear through the use of glitches. Other than the Bird type, glitch types are the result of the game reading other data as if it were types. The Bird type was programmed into the code of the Generation I and II games, but was not given to any real Pokémon; however, several glitch Pokémon use this type.

Dual-type Pokémon glitch

Main article: List of glitches in Generation I → Dual-type Pokémon glitch

In Generation I, Pokémon with two types that have a weakness and resistance to the same type receive neutral damage from that type, but the incorrect message is displayed.

For example, Grass-type moves do neutral damage to Gyarados, but if Gyarados is hit by a Grass-type move, the game erroneously states that the attack is "not very effective...".

The game prioritizes on which message to display for each 'special' scenario (where normal damage is not dealt) based on each scenario's internal ordering. The higher the ordering determines what message the game will display. Grass against Water as 200% damage for instance is the 4th entry, whilst Grass against Flying as 50% damage is the 27th. Consequently in this example the game chooses the message for scenario #27, returning the wrong message "It's not very effective..."

This glitch does not occur in Pokémon Stadium.

If an attack is super effective or not very effective against one type and does no damage against another type (for example, Dig against Charizard), the game will erroneously state that the attack missed.
