Water Pokémon

Water type (みずタイプ Mizu taipu in Japanese) is one of the eighteen Pokémon elemental types. It is also one of the three Starter types, forming a perfectly triangular relationship with Fire and Grass.

There are more Pokémon of this type than any other type due to the large number of marine creatures to base species from. Most Pokémon of this type also have another type, representing the biodiversity of marine creatures. Water is notably the second type to have been paired with every other type - the Fire/Water Volcanion completed all possible pairings.

Most Water-type Pokémon are based on creatures that live on water, or use water for their disposition. Their attacks involve use of water, if not, attacks that can be done only by marine creatures (like Clamp, Crabhammer and Razor Shell).

Famous Water-type Pokémon Trainers include Misty, the second Kanto Gym Leader; Wallace, the first eighth Hoenn Gym Leader-turned-Champion and his replacement Juan; Crasher Wake, the fourth Gym Leader of Sinnoh; Cress, one of Striaton City's three Gym Leaders in Unova; Marlon, the eighth Gym Leader of Humilau City in Unova; Siebold, one of the Kalos Elite Four; and Lana, an Akala Island Trial Captain in Alola.
