Omanyte is technically a pre-evolution of Omastar, but it holds its own in formats where Eviolite is allowed. Watch the Grass matchup though — quadruple damage means one hit can end it. Watch the Grass matchup though — quadruple damage means one hit can end it.
Omanyte's spread isn't flashy. Defense leads, HP trails, 2 stats clear the bar. Tough to catch and worth 1 Defense EV, on a medium-fast 1M XP curve.
Although long extinct, in rare cases, it can be genetically resurrected from fossils.
Omanyte Weakness
VulnerableType-wise, Omanyte takes extra damage from Grass, Electric, Fighting, and Ground. Watch out for Grass attacks, those deal 4x damage. It resists 5 types, giving it decent defensive coverage. Omanyte's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- Only 15 types exist — Dark, Steel, and Fairy are absent
- Ghost has no effect on Psychic (a known bug, fixed in Gen II)
- Special stat governs both offense and defense — no Sp.Atk / Sp.Def split
Omanyte starts a line toward Omastar. Can't breed this Rock/Water type (355 stats), so keep the evolution path going. Evolving adds up to 140 stat points total.
How to Evolve
Best Build

Try selecting a different game/generation filter, or check back later.
TMs define Omanyte's movepool. The natural moves cover basics with Hydro Pump and Surf, but the real versatility comes from technical machines giving it Normal and Ice coverage. That's where the options open up.

Best Locations
Omanyte isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Omastar to unlock its full potential. At 355 BST, it's a stepping stone rather than a team anchor.
Omanyte's biggest threats include Venusaur (Grass), Jolteon (Electric), and Hitmonlee (Fighting), all carrying super-effective STAB moves. Venusaur is the most dangerous since Grass moves deal 4x damage. Ground-type attackers are also a problem. At base 35 Speed, Omanyte won't outrun any of these threats so switching to a resist is usually the safer play.
Omanyte evolves into Omastar at level 40. Omanyte is the base form of this evolutionary line.
Omanyte fills the trick room role. It's a special attacker with base 90 Sp. Atk. Base 35 Speed is low. Priority moves or Trick Room are the way to go.
Omanyte appears in 19 games, including Yellow, Red & Blue, and Gold & Silver.
