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

It evolves from Shellder when exposed to a Water Stone.

Biology

Cloyster is a black, pearl-like Pokémon. It is encased inside a light grey 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 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.

It 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. 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. 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 propelling it through with siphon-jet propulsion. It lives on the sea floor, nestled among the rocks and coral.

Trivia

• Cloyster has the highest Defense base stat of all Water-type Pokémon and all Ice-type Pokémon.

Origin

It appears to be based on a bivalve, more specifically the genus spondylus, with a black pearl as its head.

Name origin

Cloyster is a pun on cloister (to seclude or shelter oneself) which contains the word oyster, or is a portmanteau of clam and oyster.

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