Omastar Best Moveset
Dropped from A-tier as 115 Sp. Atk at 55 Speed behind Rock/Water TermStab couldn't keep up without rain. AbilitySwift Swim doubles that Speed in rain, and hidden AbilityWeak Armor trades Defense for Speed on hits. The moveset runs special offense at either fast-in-rain or slow-and-bulky at 125 Defense. C-tier because the rain dependency limits consistency.
Rock/Water had no reliable Water STAB in Gen I (Red & Blue). Omastar's 115 Special was impressive but there wasn't much worth doing with it offensively.

Spikes and Surf off 115 Sp. Atk in Gen II (Gold & Silver). Setting hazards while hitting hard was a combination few Pokemon could match.

Swift Swim made it dangerous in rain. 115 Sp. Atk with Rain-boosted Surf swept teams that weren't prepared in Gen III (Ruby & Sapphire).

Same rain sweeper role plus Stealth Rock utility in Gen IV (Diamond & Pearl). Omastar could support the team AND sweep in the right conditions.
Special Sweeper Moveset

Shell Smash arrived but Drizzle plus Swift Swim was banned in Gen V (Black & White). Without permanent rain, Omastar lost its best sweeping engine.
Special Sweeper Moveset
- Ice Beam
- Shell Smash
- Surf
- Hidden Power Grass
Recommended Teammates
Shell Smash was still powerful but 4x Grass weakness and 55 base Speed before boosting made finding the setup turn tough in Gen VI (X & Y).
Special Sweeper Moveset
- Shell Smash
- Ice Beam
- Surf
- Earth Power
Recommended Teammates
Same issues in Gen VII (Sun & Moon). Shell Smash was the only plan, and the metagame had more ways to stop setup sweepers than ever.
Special Sweeper Moveset
- Ice Beam
- Surf
- Shell Smash
- Earth Power

Found a niche in lower tiers of Gen VIII (Sword & Shield) with Shell Smash. Too strong for the bottom but not good enough for higher formats.

- Earth Power

- Ice Beam

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 |

Base Stats
Defense and Sp. Atk carry most of Omastar's stat budget. Speed's the obvious dump stat. Tough to catch and yields 2 Defense EVs. Follows a medium-fast 1M XP curve.
Weighed down by a large and heavy shell, Omastar couldn’t move very fast. Some say it went extinct because it was unable to catch food.
Omastar Guide
Swift Swim changes the entire equation for Omastar. The 495 BST doesn't tell the full story. Ranked C-Tier as a wallbreaker.
Swift Swim is what you want on Omastar. Every competitive set worth running is built with that ability in mind. The alternatives (Shell Armor, Weak Armor) work on paper but Swift Swim is what makes Omastar worth using. On wall sets, Swift Swim pairs with Omastar's base 125 Defense to absorb physical hits on the switch.
At base 55 Speed, it won't be moving first often. On offense, Omastar is a special attacker with base 115 Sp. Atk. Defensively? Enough bulk to take a hit or two. Best used as a wallbreaker.
Run Shellsmash, Ice Beam, Scald, and Ancientpower on Omastar. Shellsmash is the most common pick at 0% usage. Scald provides reliable STAB damage.
Game Availability
One of the original 151, Omastar has appeared in 19 games — most mainline games. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
