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

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

Biology

Physiology

Omastar has a heavy, pale yellow, helix shell dotted with spikes. It has a sky blue body with ten tentacles, four of which are longer than the other six. Omastar has a squid-like beak and eyes with vertical-line pupils.

Gender differences

None.

Special abilities

Most of Omastar's abilities are the same as Omanyte's, only stronger. Omastar can now learn how to use Stone Edge. Like most fully-evolved Pokémon, it can learn Hyper Beam and Giga Impact.

Behavior

Omastar, unlike Kabutops, is far more defensive. While Kabutops prefers to slice prey apart or swim after them, Omastar does not. Omastar has a high Special Attack suggesting that it prefers waiting for prey to come near it so it can attack. It is not as fierce as Kabutops and probably does not move as much either, preferring to stay rooted to a spot, waiting.

Habitat

Sea

Sea Pokémon

The exact habitat of Omastar is unknown, but so far Helix Fossils are only found in the Kanto region.

Diet

Pokédex information indicates that Omastar would eat Shellder in the wild by cracking open their shells with sharp fangs and sucking out the insides.
