In-Depth Analysis
Omastar's 495 base stat total marks it as a slow bruiser that trades speed for raw hitting power. Defense (125) carries most matchups, but a low Speed stat of 55 means careful positioning matters.
Defensively, the Rock, Water combination gives Omastar 5 resistances and 4 weaknesses to plan around. Watch out for Grass moves in particular — they land for 4× damage. Offensively it pressures 6 types with super-effective STAB coverage.
A low catch rate of 45 makes Omastar a genuinely tough catch; bring strong balls and status moves. It levels on the Medium experience curve. Defeating it grants Defense +2 EVs, which is worth remembering when EV-training your own team.
