Unused type combinations

There are 18 elemental types in the Pokémon games, which means a total of 171 unique combinations are possible. However, even with 890 Pokémon in the games now, not all type combinations have yet been used. This page lists all the unused type combos in the game. It's fun to think what Pokémon with these types would look like!

We also list some combinations that have been used, but only for legendary Pokémon or Mega Evolutions. Note that Psychic/Dragon appears in both sections as it has been used by both legendaries and Megas, but not regular Pokémon.
