Omastar (Japanese:オムスターOmstar) is a dual-typeRock/WaterFossil Pokémon introduced inGeneration I.

Itevolves fromOmanyte starting atlevel 40.

Biology

Omastar is acephalopodmolluskPokémon similar to anammonite ornautilus. 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, which serves todefend it fromcritical blows. 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.

In prehistoric times, Omastar swam theseas in search of prey. Omastar uses its highly developed tentacles to ensnare its prey before biting down with its beak, which has enough force to crush rocks. Omastar's diet includesShellder; it cracks their shells with its beak before sucking out the contents. Omastar was in turn preyed upon byCarracosta. Despite Omastar's power and dexterity, it is slow and can only catch prey that are within reach of its tentacles. It is believed that Omastar's extinction was a consequence of the increasingly heavy weight of its shell that affected its mobility, including its hunting. Omastar is thought to be a distant ancestor toOctillery.
