Omastar

 is one of types of Pokémon species. It is the final evolved form of Omanyte and were introduced in the first generation of Pokémon video games.

Omastars are ancient Pokémon that were extinct for ages. Like the Omanyte before it, Omastars would traverse the seas of the Pokémon universe. It is believed that they became extinct due to their spiral on their shell becoming too large. Scientists managed to revive the species along with the Omanyte using modern technology.
