Basics
Omastar is a Rock/Water-type Pokémon. Its 100% IV CP is 1,592 at level 20 (raids, eggs and research), 1,990 at weather-boosted level 25 and up to 3,150 at level 50. It is most vulnerable to Grass attacks (2.56×) and also weak to Electric/Fighting/Ground attacks (1.6×). It resists Normal/Ice/Poison/Flying/Fire attacks. In raids, Rock Throw + Hydro Pump is its strongest moveset (level 40, 100% IVs). As your buddy, it earns 1 Candy every 5 km you walk together.

Omastar uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.
