Cloyster [Reverse Holo] Card Facts & History

5 facts about this card

Card History

Cloyster #20 was released in EX FireRed & LeafGreen and, like other cards in the set, also had a Reverse Holofoil version—giving this rare ex-era pull an extra layer of collector appeal.

Card History

This specific Cloyster card is remembered for its Poké-Body, Exoskeleton, which reduces incoming attack damage and perfectly matches Cloyster’s long-standing identity as one of Kanto’s toughest shell-armored Pokémon.

In-Game

Cloyster is Pokédex #091, and in Pokémon FireRed it could be obtained by evolving Shellder—making its appearance in a FireRed & LeafGreen-themed set a neat callback to its actual role in those games.

Cultural Impact

Early official depictions gave Cloyster’s face the look of a black pearl, a strange and memorable design detail that helped make this Gen I Pokémon feel mysterious even among the original 151.

Artist

The card was illustrated by Aya Kusube, an artist whose softer, storybook-style Pokémon art gives this defensive Cloyster card a more collectible personality than its battle text alone suggests.
