Omastar

Omastar, known as オムスター in Japanese, is a dual-type Rock/Water Fossil Pokémon from the Pokémon series. It evolves from Omanyte and resembles an ammonite, featuring a spiraled, spiked shell. Omastar has a blue body with numerous tentacles used for capturing prey. Its mouth possesses a powerful bite, capable of crushing the shells of its victims. It is believed that Omastar went extinct due to its shell becoming too heavy, hindering its movement and hunting abilities. In the games, players can obtain Omastar by reviving a fossil. This Pokémon maintains its unique design across various cultural adaptations, with its name remaining consistent in English (Omastar) and Japanese (オムスター).
