# Pokémon With Unique Type Combinations: The 44 Pairs Only One Line Has

Of the 136 type pairs that Pokémon species hold, 44 belong to a single evolution line. Twenty-one of them belong to one lone Pokémon, like [Tyranitar](https://pokee.si/pokemon/tyranitar) (Rock/Dark) or [Volcanion](https://pokee.si/pokemon/volcanion) (Fire/Water).

Here we use one rule. A pair is unique when only one evolution line holds it among species, and the order of the two types does not matter. So Ghost/Water and Water/Ghost are the same pair. Alternate forms such as Mega Evolutions and regional forms are handled in their own section.

## How common each pair is

Counting evolution lines, not Pokémon, the 136 pairs fall like this:

- 44 are held by exactly one line.
- 38 are held by two lines.
- 47 are held by three to five lines.
- 7 are held by six or more.

The most shared pair is Normal/Flying, held by 14 lines. Flying/Bug follows with 10, then Water/Rock with 7. Of the 44 unique pairs, 36 belong to ordinary lines and 8 belong only to Legendary, Mythical, Ultra Beast or Paradox Pokémon.

Every one of the 44 has its own page on the site, so each pair below links to its [dual-type weakness page](https://pokee.si/types/dual).

## The unique pairs by generation

The Pokémon column shows every species that holds the pair, which is more than one for a line. A pair is placed in the generation where its first holder appeared.

| Type pair | Pokémon | Species |
| --- | --- | --- |

| [Fighting/Ground](https://pokee.si/types/fighting-ground) | [Great Tusk](https://pokee.si/pokemon/great-tusk) | 1 |
| [Electric/Rock](https://pokee.si/types/electric-rock) | [Iron Thorns](https://pokee.si/pokemon/iron-thorns) | 1 |

Generation 9 adds the most, 9, and Generation 1 the fewest, with only Poison/Flying for the [Zubat](https://pokee.si/pokemon/zubat) line. The single-species entries include the Paradox Pokémon Great Tusk, Iron Thorns and Iron Valiant, and Munkidori and Fezandipiti. [Pokémon Database](https://pokemondb.net/pokedex/tyranitar) confirms the types of Tyranitar, Empoleon and Bibarel, which are three of the single-species pairs.

## Pairs that look unique but are not

Some pairs people call one-offs are not in the list. [Frillish](https://pokee.si/pokemon/frillish), [Jellicent](https://pokee.si/pokemon/jellicent) and [Basculegion](https://pokee.si/pokemon/basculegion) share Water/Ghost across two lines. [Marshadow](https://pokee.si/pokemon/marshadow) shares Fighting/Ghost with [Annihilape](https://pokee.si/pokemon/annihilape). Pokémon Database lists Marshadow as Fighting/Ghost and Jellicent as Water/Ghost.

## Unique pairs and their weaknesses

A unique pair can be a tough one to defend with. [Amaura](https://pokee.si/pokemon/amaura) and [Aurorus](https://pokee.si/pokemon/aurorus) hold [Ice/Rock](https://pokee.si/types/ice-rock), which takes 4× damage from both Fighting and Steel. [Snover](https://pokee.si/pokemon/snover) and [Abomasnow](https://pokee.si/pokemon/abomasnow) hold [Grass/Ice](https://pokee.si/types/grass-ice), which takes 4× from Fire. [Snom](https://pokee.si/pokemon/snom) and [Frosmoth](https://pokee.si/pokemon/frosmoth) hold [Ice/Bug](https://pokee.si/types/ice-bug), and Pokémon Database shows 4× weaknesses on Frosmoth as well. The dual-type pages list every matchup.

## Forms change the answer

Species typings are one thing. Alternate forms can add a type pair that a species never has, or hand a species pair to a second line.

Eight pairs are held only by forms, and by no regular species:

- Electric/Psychic: Alolan Raichu
- Ice/Steel: Alolan Sandshrew, Alolan Sandslash
- Ice/Fairy: Alolan Ninetales
- Electric/Grass: Hisuian Voltorb, Hisuian Electrode, Mow Rotom
- Dragon/Fairy: Mega Altaria
- Fire/Electric: Heat Rotom
- Fire/Ice: Zen Galarian Darmanitan
- Normal/Ghost: Hisuian Zorua, Hisuian Zoroark

Seventeen of the 44 unique pairs also appear on a form from a different line. Wash Rotom is Electric/Water like [Chinchou](https://pokee.si/pokemon/chinchou), the Wellspring Mask [Ogerpon](https://pokee.si/pokemon/ogerpon) is Grass/Water like Lotad, Alolan Geodude is Electric/Rock like [Iron Thorns](https://pokee.si/pokemon/iron-thorns), and Mega Lopunny is Normal/Fighting like Stufful. These pairs are unique among species but not once forms are counted.

## What about pairs nobody has

Of the 153 possible pairs of two different types, nine have no Pokémon at all, according to Pokémon Database. The [type combinations that don't exist](https://pokee.si/articles/pokemon-type-combinations-that-dont-exist) article lists them. Fire/Fairy and Bug/Dragon are two. For matchups, [dual-type weaknesses explained](https://pokee.si/articles/dual-type-weaknesses-explained) shows how to read any pair, and [Pokémon with 4× weaknesses](https://pokee.si/articles/pokemon-with-4x-weaknesses) covers the extreme ones.

## Questions people ask

### Which Pokémon have a unique type combination?

In the pokee.si data, 44 of the 136 type pairs are held by only one evolution line. Twenty-one of those belong to a single species, such as Tyranitar (Rock/Dark), Volcanion (Fire/Water) and Terrakion (Fighting/Rock).

### What is the rarest type combination in Pokémon?

The narrowest are the 21 pairs held by a single species. If you mean a pair that no Pokémon holds at all, Pokémon Database says 9 of the 153 pairs are unused.

### Is Water/Ghost unique to Jellicent?

Not in our data. Two evolution lines hold it: Frillish and Jellicent, and Basculegion. A pair counts as unique here only when one line holds it.

### Does a Pokémon's form change whether a typing is unique?

It can. A pair held by one species line can also appear on an alternate form from another line. Wash Rotom, for example, is Electric/Water like Chinchou and Lanturn. We list those cases separately.

### Which generation added the most unique type pairs?

Generation 9, with 9 of the 44, followed by Generations 4 and 8 with 7 each. Generation 1 added only one, Poison/Flying for the Zubat line.
