How to Get Omastar in Emerald
No wild Omastar exists in Emerald. Bring an Omanyte over and raise it to level 40, since the ancient ammonite cannot be revived from any Hoenn fossil.

Omastar Weakness
Omastar's Rock/Water typing leaves it vulnerable to Grass, Electric, Fighting, and Ground. Grass hits land at 4x, so they're the biggest threat. 5 resistances help offset the weaknesses. Omastar's physical bulk (base 125 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 4x (Critical) | Grass |
| 2x (Weak) | Electric, Fighting, Ground |
| 0.5x (Resist) | Normal, Ice, Poison, Flying |
| 0.25x (Resist) | Fire |
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move

Omastar Evolutions
Evolved from Omanyte. Omastar is the final form in this two-stage line. Plenty of partners for breeding via two egg groups. Eggs are slow to hatch. HP grew the most through evolution (+35 over Omanyte), and Omastar peaks at 495 total stats. View every chain in the Evolution Chart.
How to Evolve
Breeding
Breed with Omastar to get Omanyte eggs using 58 partners from the Water 1 and Water 3 egg groups. Notable egg moves include Aurora Beam, Bubble Beam, Haze and 4 more.
E Omastar Best Moveset
Omastar anchors rain teams as a special attacker, with AbilitySwift Swim doubling Speed while rain-boosted MoveSurf fires from 115 Sp. Atk at devastating power. The moveset adds MoveIce Beam for Grass-types that resist Water and MoveRock Slide from the physical side. The 4x Grass weakness means any Grass move, even resisted ones from off-type attackers, threatens a knockout.
