From Bulbapedia, the community-driven Pokémon encyclopedia.
While many type combinations are actually quite common (sometimes even more so than Pokémon of single types), there are several Pokémon which have type combinations unique to either their species or their evolutionary family. These Pokémon are listed below as of Generation VI.
Many Pokémon have two types, rather than just one. The complex nature in which types can be arranged means there are a possible 324 different type permutations (including single types). However, due to the games' advantage/disadvantage multiplication system, a Pokémon which is Dark/Ghost is treated the same as one that is Ghost/Dark. As such, there are 171 distinct type combinations.
For the purposes of this list, type combinations are considered commutative; that is to say, Spiritomb and Sableye would be treated as having the same type combination as they have the same weaknesses and resistances.
