IVs never change when a Pokémon evolves, so the spread you want depends on the league you are building for.

That answers a different question from the rest of this page. The IV ranks above tell you which Omastar to build; this tells you whether it is worth building at all. Rankings and movesets come from PvPoke, who run the battle simulation behind them, and change as the meta does.

How to find a good Omastar

The search-string generator builds a string you can paste into the search bar in Pokémon GO. It finds catches whose CP, HP and appraisal stars match the top IV spreads above, including pre-evolutions, so you can check a whole storage box in one go.

To check a Omastar you already own, open the IV ranker and set its IVs.
