The Story

What the Pokédex says

  • Shield

    Once it slams its shell shut, it is impossible to open, even by those with superior strength.

  • Sword

    Its shell is extremely hard. It cannot be shattered, even with a bomb. The shell opens only when it is attacking.

  • Let’s Go, Eevee!

    For protection, it uses its harder-than-diamond shell. It also shoots spikes from the shell.

  • Ultra Moon

    Slowpoke tails are its favorite food. It has even been known to come up on land to look for Slowpoke from time to time.

10 more entries from older games
  • Ultra Sun

    If areas of Cloyster’s very hard shell get damaged, those areas swell, gradually growing into large sharp spikes.

  • Moon

    Excavation of the tombs of ancient hunting tribes has turned up many spears tipped with spikes that had fallen off this Pokémon’s shell.

  • Sun

    Its hard shell cannot be shattered—not even by a bomb. The contents of the shell remain unknown.

  • Alpha Sapphire

    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.

  • X

    Cloyster that live in seas with harsh tidal currents grow large, sharp spikes on their shells.

  • White 2

    It fights by keeping its shell tightly shut for protection and by shooting spikes to repel foes.

  • LeafGreen

    When attacked, it launches its horns in quick volleys. Its innards have never been seen.

  • Emerald

    It swims in the sea by swallowing water, then jetting it out toward the rear. The CLOYSTER shoots spikes from its shell using the same system.

  • Crystal

    Even a missile can't break the spikes it uses to stab opponents. They're even hard­ er than its shell.

  • Yellow

    For protection, it uses its harder- than-diamonds shell. It also shoots spikes from the shell.
