From Bulbapedia, the community-driven Pokémon encyclopedia.

Omastar (Japanese: オムスター Omstar) is a dual-type Rock/Water Fossil Pokémon introduced in Generation I.

It evolves from Omanyte starting at level 40, after it is revived from a Helix Fossil.

Biology

Omastar is a Pokémon similar to an ammonite. Its sky blue body has several tentacles; the tentacles toward the front are shorter and thicker than those in the back. There is a pale yellow, helix spiraled shell on its back. Several sharp spikes line the shell's midsection from the front to about halfway down its back. The shell's rim has two circular indents where Omastar's eyes are visible. Its eyes have yellow sclerae and vertically-slit pupils. It has an oval mouth with a four-sectioned, fang-like beak.

It is believed that Omastar's extinction was a consequence of the increasingly heavy weight of its own shell that affected its mobility, including its hunting. Omastar swam the seas in search of prey, including prehistoric Shellder. Omastar's used its tentacles to ensnare its prey before biting down with the deadly force of its beak. With the shell broken, it would suck out the contents. Omastar was in turn preyed upon by Carracosta. Omastar is thought to be a distant ancestor to Octillery.

Trivia

In early English-language promotional material for Pokémon Red and Blue, Omastar was originally known as "Kargo". This name is derived from "escargot" (French for snail).

Origin

Omastar appears to be based on a type of ammonite. In addition, its method of grabbing prey and cracking their shells with ring-shaped mouths may be based on Anomalocaris.

Name origin

Omastar's name is a combination of its Japanese name, a phonetic anagram of ammonite, and star (based on its body shape).

Omstar is a combination of オウムガイ ōmugai (nautilus) and star.
