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

It evolves from Omanyte starting at level 40.

Contents

Biology

Physiology

Omastar has a heavy, pale-yellow, helix shell dotted with spikes. It has a sky-blue body with 10 tentacles (four of them 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 finally learn how to use Stone Edge. Like most fully evolved Pokémon, it can learn Hyper Beam and Giga Impact.

Behavior

Omastar, unlike Kabutops, the other fully-evolved Generation I fossil Pokémon, 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 isn't fierce like Kabutops and probably doesn't move as much either, preferring to stay rooted to a spot waiting.

Habitat

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

Diet

Main article: Pokémon food

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

In the anime

Omastar with other fossil Pokémon

Omastar first appeared in Attack of the Prehistoric Pokémon, alongside all the other Generation I Fossil Pokémon. They were sleeping under Grandpa Canyon until a dynamite blast woke them up. The Water/Rock-typed Fossil Pokémon chased Ash Ketchum and Team Rocket until Aerodactyl showed up and scared them off.

Omastar also appeared in Fossil Fools, alongside its pre-evolved from; Omanyte. These Pokémon were discovered to be living in the Ruins of Alph, but they moved into a museum.

Dr. Yung uses a Mirage Omastar in The Mastermind of Mirage Pokémon.

Another one appeared in Dealing With Defensive Types!.

Gen Game Pokédex entry
I Red A prehistoric Pokémon that died out when its heavy shell made it impossible to catch prey.
Blue A prehistoric Pokémon that died out when its heavy shell made it impossible to catch prey.
Yellow Sharp beaks ring its mouth. Its shell was too big for it to move freely, so it became extinct.
Stadium Attacks by ensnaring its enemy with its tentacles and biting with sharp fangs. Its overly-large shell makes it sluggish.
II Gold Apparently, it cracked Shellder's shell with its sharp fangs and sucked out the insides.
Silver Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs.
Crystal Its heavy shell allowed it to reach only nearby food. This could be the reason it is extinct.
Stadium 2 Apparently, it cracked Shellder's shell with its sharp fangs and sucked out the insides.
III Ruby Omastar uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.
Sapphire Omastar uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.
Emerald An Omastar uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large, making its movements slow and ponderous.
FireRed Its tentacles are highly developed as if they are hands and feet. As soon as it ensnares prey, it bites.
LeafGreen Despite having strong fangs and tentacles, it went extinct when its heavy shell made it unable to catch prey.
IV Diamond It is thought that this Pokémon became extinct because its spiral shell grew too large.
Pearl It is thought that this Pokémon became extinct because its spiral shell grew too large.
Platinum It is thought that this Pokémon became extinct because its spiral shell grew too large.

Trivia

  • Omastar originally had the name "Kargo", which, when taken with Omanyte's beta name "Ess", forms a misspelling of "escargot", which is French for snail.
  • While Omastar could Learn Rollout by tutor in Emerald, it cannot learn it in Platinum. It can still be taught it as an Omanyte, though.
    • The opposite is true regarding Mud-Slap; while Omastar cannot learn it in Emerald, it now can in Platinum.
  • Omastar's Generation I backsprites shows it has spikes at the back of its shell; these spikes were removed in the later sprites.
  • Omastar has the highest Special Attack stat of any Water-type (excluding legendaries). Coincidentally, this is also the highest Special Attack of any Rock-type.

Origin

It seems to be based on a type of ammonite.

Name origin

Omastar's name is a combination of オウムガイ ōmugai, the Japanese word for nautilus, and ammonite, both names of the creatures on which it is based, as well as star, referring to the shape of its body.

In other languages

  • German: Amoroso - From ammonite.
  • French: Amonistar - From ammonite and star.
  • Korean: 암스타 Amseuta
