From Bulbapedia, the community-driven Pokémon encyclopedia.
This list details every possible Pokémon type combination and the number of Pokémon that have that combination.
Pokémon can have either a single type or two distinct types. Consequently, there are 324 possible ways to assign types to Pokémon (18 single types + 18 × 17 dual types). However, type effectiveness does not distinguish between a Pokémon's first and second types when calculating damage; that is, a Dark/Ghost-type Pokémon is treated the same as a Ghost/Dark-type Pokémon. Therefore, instead of considering every permutation, this list only considers type combinations, of which there are 171 (18 single types + 18 × 17 / 2 dual types). For example, Spiritomb and Sableye have the same type combination.
Of the total 171 possible type combinations, only nine have not yet been assigned to any Pokémon. 19 type combinations have only been assigned to a single Pokémon, and a further 16 that have been assigned to multiple Pokémon are only used in a single evolutionary family. The other 127 type combinations have been assigned to multiple unrelated Pokémon.
For the purposes of this list, each form with a different type than another of the same Pokémon's forms counts as a different Pokémon. For example, Darmanitan counts once each towards pure Fire, Fire/Psychic, Ice, and Ice/Fire; while Deoxys only counts once towards Psychic. Despite having one form of each type, Arceus and Silvally are only counted once each (under Normal only), though the parenthetical total includes these two under each pure type.
All type combinations ranked by abundance
All type combinations and their abundance
In the table below, each column counts the number of Pokémon of that type introduced in that generation, who has this type combination as of Generation IX. Therefore, Magnemite and Magneton are considered Electric/Steel, Rotom's forms are each counted separately and all of the pre-Generation VI Pokémon that were given the Fairy type are counted as Fairy types rather than the types they had in their introduction generation. For convenience, Arceus and Silvally count only towards the Normal type.
