**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 sky-blue ammonite Pokémon, with several tentacles and a pale yellow, helix spiraled shell on its back. Several sharp spikes line the shell's midsection, spanning from its forefront to just a little towards its back. Its shell constantly grows, getting heavier over time and thus limiting its mobility. It is the weight of the shell that is most often cited as the cause for Omastar's extinction. The shell's hem has two circular indents where Omastar's eyes come out. Its eyes have yellow sclerae and vertically-slit pupils. It has an oval mouth with a four-way jawed, fang-like beak. Once caught, it never lets go of prey, immediately biting down on its victim with immense power.

Before its own shell led to its extinction, Omastar swam the seas in search of prey. Even the hard shells of prehistoric Shellder stood no match to Omastar's deadly powerful bite, and were quickly made a meal of by having their insides sucked out. Omastar may be linked to Octillery, seen as its distant ancestor.

### Major appearances

## 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*).
* Omastar is the only Fossil Pokémon whose extinction has been explained: its shell was too heavy for it to move, leading it to die out from starvation.
	+ This explanation may also refer to the giant orthocone, ancestor to the modern octopus. The orthocone resembled a slow, cumbersome octopus with a long, pointed shell.

### Origin

It seems to be based on a type of ammonite.

#### Name origin

Omastar's name is a combination of 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*.
