Types (Japanese: タイプ Type) are a property for Pokémon species and certain Master Trainers specializing in specific types. Each type has three properties: which types it is super effective against, which types it is not very effective against, and which types it is completely ineffective against. There are 18 types in total.
A Pokémon may have either one or two types. For instance, Charmander is a Fire type, while Bulbasaur is both a Grass type and a Poison type. With the current 18-type system, there are a possible 324 different type permutations; meaning that there are 171 type combinations. A move may have only one type. Master Trainers usually chose or are destined towards a type, and usually focus on that specific type and only capture Pokémon with that type.
