Cloyster (Japanese: パルシェン Parshen) is a dual-type Water/Ice Pokémon introduced in Generation I.

It evolves from Shellder when exposed to a Water Stone.

Biology

Cloyster is a black bivalve mollusk Pokémon. It is encased inside a light-gray shell, which is surrounded by a second jagged, blue-violet outer shell casing. It has one barb-like spike protruding from above its head, and multiple conical horns on its outer shell. Its shell is harder than a diamond with spikes that are even harder; harsh tidal currents will affect the size and sharpness of these spikes. On its pearl-like face, it has two white eyes and a mouth. Aside from its face and head, its internal anatomy has never been seen. Once it has shut itself in, it is impossible to open its shell from the outside. This impressive defense allows it to withstand anything from a bomb blast to even a missile strike.

Cloyster typically only opens its shell to attack an opponent. However, it is fully capable of retaliating against any enemy with its shell tightly closed. With rapid succession, it launches its spikes at the foe, keeping them repelled. In Generation I, Clamp was its signature move. The same projectile system it uses to launch its spikes is also used for swimming. It swallows seawater and then ejects it towards the rear, pushing it through with siphon-jet propulsion. Being the result of Shellder evolving through an Evolution stone, Cloyster is rarely found in the wild, though they can be found on the sea floor, nestled among the rocks and coral; however, it will actively hunt on land for Slowpoke tails. Cloyster and its pre-evolved form, Shellder, are relatives of Gastrodon. Kingler is a natural predator of Cloyster.

Trivia

  • Cloyster is tied with Mega Slowbro for the highest base Defense stat of all Water-type Pokémon.
    • Slowbro's tail has an attached Shellder, which grows to engulf it during Mega Evolution. This may have been an intended parallel.
  • Cloyster and its pre-evolved form share their category name with Clamperl. They are all known as the Bivalve Pokémon.

Origin

Cloyster appears to be based on a bivalve of the genus Spondylus with a black pearl as its head.

Name origin

Cloyster may be a combination of clam and oyster, as well as a play on cloister (to seclude or shelter oneself).

Parshen may be a combination of パール pearl and シェル shell.
