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.

BDSP 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.

Omastar Brilliant Diamond & Shining Pearl Guide
In Brilliant Diamond & Shining Pearl, Swift Swim changes the entire equation for Omastar. The 495 BST doesn't tell the full story. Ranked B-Tier as a wallbreaker. Earthpower with Focus Sash is the standard set.
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.
In Brilliant Diamond & Shining Pearl, run Earthpower, Shellsmash, Ice Beam, and Scald on Omastar. Earthpower 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.
