Cloyster's Water/Ice typing leaves it vulnerable to Electric, Grass, Fighting, and Rock. Cloyster's physical bulk (base 180 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokedex Entry

Cloyster is capable of swimming in the sea. It does so by swallowing water, then jetting it out toward the rear. This Pokémon shoots spikes from its shell using the same system.

Pokemon Omega Ruby / Pokemon Alpha Sapphire

Cloyster Omega Ruby & Alpha Sapphire Guide

  • For Omega Ruby & Alpha Sapphire, we rate Cloyster B-Tier: a solid option in Omega Ruby & Alpha Sapphire for the right team. At 525 BST, the stats are spread pretty evenly. Icicle Spear with Focus Sash is the standard set.

  • In Omega Ruby & Alpha Sapphire, watch for Raikou (Electric), Venusaur (Grass), and Hitmonlee (Fighting) when using Cloyster. They all hit it super-effectively with STAB. Rock-type attackers are also a problem.

  • Shell Armor protects against critical hits. That's the one you want on Cloyster. Overcoat is the hidden ability. Niche, but it has its uses. Skill Link works too if your team needs something different.

  • Base 70 Speed is workable. Faster than some, slower than many. On offense, Cloyster is a physical attacker with base 95 Attack. Defensively? Enough bulk to take a hit or two.

  • In Omega Ruby & Alpha Sapphire, run Icicle Spear, Shellsmash, Rapid Spin, and Rock Blast on Cloyster. Icicle Spear is the most common pick at 0% usage. This set covers the balanced role with a mix of damage and utility.

Game Availability

One of the original 151, Cloyster has appeared in 20 games — most mainline games. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
