List of Pokémon with unique type combinations

This is a list of Pokémon with unique type combinations across the generations. A Pokémon qualifies as having a unique type combination if no other Pokémon aside from any evolutionary relatives has that type combination. Since the game rarely makes a distinction between a Pokémon's first and second types when calculating damage, this list does not consider every permutation of types, but instead considers only combinations. In other words, Pokémon such as Spiritomb (a Ghost/Dark-type Pokémon) and Sableye (a Dark/Ghost-type Pokémon) are treated as having the same type combination.

Trivia

As of Generation IX:
- 21.0% of all (162) used type combinations are unique to a single Pokémon (18 combinations) or evolutionary line (16 combinations).
- Zubat and Golbat are the oldest Pokémon with unique type combinations, spanning back since Generation I. Meanwhile, the oldest single Pokémon with a unique type combination is Tyranitar, spanning back since Generation II
- Zubat, Golbat, and Crobat are the only Flying-type Pokémon to have a unique type combination, while Snover and Abomasnow are the only Grass-type Pokémon with this distinction.
Several single-type Pokémon—Tangela, Dratini, Dragonair, Sudowoodo, Umbreon, Misdreavus, and Flying-type Arceus—were unique in their single typing when introduced, but later generations introduced more Pokémon with those types.
Generation V introduced the most Pokémon with unique type combinations, with 32.
Generation IX introduced the fewest Pokémon with unique type combinations, with 9.
Mega Altaria is the only Mega-Evolved Pokémon with a unique type combination to not be shared with its base form, though Mega Sceptile previously held this title as well prior to the introduction of Alolan Exeggutor.
Dratini, Dragonair, Nincada, and Surskit are the only Pokémon that are not fully evolved to have had unique type combinations not shared by their fully evolved forms.
- Sandy Cloak Wormadam is the only fully-evolved dual-type Bug/Ground Pokémon.
  - Prior to Pokémon Omega Ruby and Alpha Sapphire, Wigglytuff was the only fully-evolved dual Normal/Fairy Pokémon.
- A fully evolved pure Dragon-type Pokémon would not be introduced until Generation V, while Dratini and Dragonair lost their unique status in Generation III with the introduction of Bagon and Shelgon.
While not evolutionary relatives, Carbink and Diancie are the only dual-type Rock/Fairy Pokémon; however, some Pokémon that are otherwise related to each other had unique type combinations:
- The eon duo (Latias and Latios) were the only dual-type Dragon/Psychic Pokémon until the debut of Ultra Necrozma in Pokémon Ultra Sun and Ultra Moon, released during Generation VII.
- Lunatone and Solrock (which are often considered counterparts) were the only dual-type Rock/Psychic Pokémon until the debut of Iron Boulder in The Indigo Disk DLC expansion for Pokémon Scarlet and Violet, released during Generation IX.
Several Pokémon had a unique type combination until the introduction of specific Pokémon introduced during a generation.
- These Pokémon had a unique type combination until the release of Pokémon Omega Ruby and Alpha Sapphire, released during Generation VI:
  - Numel and Camerupt were the only dual-type Fire/Ground Pokémon until the debut of Primal Groudon.
  - Pirouette Forme Meloetta was the only dual-type Normal/Fighting Pokémon until the debut of Mega Lopunny.
