Types

Types are aspects of Pokémon and attacks, which give them an advantage over some types but a disadvantage over others. There are 18 types in total.

Each Pokémon can have one or two types. When it has only one type, it's called a pure-type Pokémon. When it has two types, it's called a dual-type Pokémon, one of types is called the primary type and the other the secondary type. Attacks, however, can have only one type.

Certain Pokémon may have different types among distinct forms.

Type effectiveness
There are several dependencies between types:
 * When a Pokémon is weak to a specific type, an attack of this type is super effective against it and its damage is multiplied by 1.6.
 * When a Pokémon is resistant to a specific type, an attack of this type is not very effective against it and its damage is multiplied by 0.625.
 * When a Pokémon is immune to a specific type, an attack of this type is not effective or ineffective against it and its damage is multiplied by 0.391.
 * When a Pokémon uses an attack of the same type as itself, its damage is multiplied by 1.2. See STAB.

These following icons are seen as medals for catching Pokémon of specific types. They can be seen on the trainer's profile page in the medals section and in the encounter screen as catch bonuses from such medals.



Pokémon summary page backgrounds
There are different backgrounds on the Pokémon summary page depending on the Pokémon's primary type.

Prior to the release of Johto-region Pokémon, there were no backgrounds for Dark and Steel-type Pokémon, as none of the Kanto-region Pokémon had these types as primary types. Also, despite the presence of a background for Flying-type Pokémon in the game files at the launch of the game, there was no use for it until Tornadus was released.
