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.

What is Omanyte weak to?

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.

What is the best ability for Omanyte?

Run Swift Swim on Omanyte. It's the ability that defines how you build around it and the main reason it holds a competitive niche. Omanyte also gets Shell Armor and Weak Armor, but they don't compare.

What role does Omanyte play in battle?

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.

Should I use Omanyte?

Omanyte does the job early-game if you need a Rock/Water type on your team. Evolve it into Omastar before the later gyms and it holds up fine through the story.

Omanyte Weakness

Type-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.
