The Story

What the Pokédex says

  • Shield

    Omastar’s sharp fangs could crush rock, but the Pokémon can attack only the prey that come within reach of its tentacles.

  • Sword

    Weighed down by a large and heavy shell, Omastar couldn’t move very fast. Some say it went extinct because it was unable to catch food.

  • Let’s Go, Eevee!

    Its sharp beak rings its mouth. Its shell was too big for it to move freely, so it became extinct.

  • Ultra Moon

    It wraps its prey in its tentacles to immobilize them and then finishes them off with its sharp fangs.

  • Ultra Sun

    Its heavy shell is thought to be the reason this ancient Pokémon died out. It’s apparently a distant ancestor of Octillery.

  • Alpha Sapphire

    Omastar uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.

  • Y

    Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs.

  • X

    Its tentacles are highly developed as if they are hands and feet. As soon as it ensnares prey, it bites.

  • White 2

    It is thought that this Pokémon became extinct because its spiral shell grew too large.

  • HeartGold

    Apparently, it cracked SHELLDER’s shell with its sharp fangs and sucked out the insides.

  • LeafGreen

    Despite having strong fangs and tentacles, it went extinct when its heavy shell made it unable to catch prey.

  • Emerald

    An OMASTAR uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large, making its movements slow and ponderous.

  • Crystal

    Its heavy shell allowed it to reach only nearby food. This could be the reason it is extinct.

  • Yellow

    Sharp beaks ring its mouth. Its shell was too big for it to move freely, so it became extinct.

  • Blue

    A prehistoric Pokémon that died out when its heavy shell made it impossible to catch prey.
