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 overall bulk (70/125/115) lets it take a hit or two from most weaknesses before going down.
| Damage | Types |
|---|---|
| 4x (Critical) | Grass |
| 2x (Weak) | Electric, Fighting, Ground |
| 0.5x (Resist) | Normal, Ice, Poison, Flying |
| 0.25x (Resist) | Fire |
- 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
