Overview

Omastar has a high defense stat among tier 3 bosses, but it’s easy to underestimate its bulk because of a double weakness to Grass. Grass is the key to soloing Omastar. High DPS attackers with only a single type advantage such as Raikou nearly don't cut it at maxed level.

Similar to Vaporeon, Omastar has fast moves that barely pose a threat, but it can launch a devastating Hydro Pump with little notice. Its Rock-type charge moves are not resisted by the traditional Grass-type counters, are used often, and Rock Blast in particular is tricky to dodge.

Approach

Team composition

  • Grow that grass: 10 of 12 fastest counters to Omastar are Grass-types
  • Machamp and Raikou are viable near max level, if already powered up
  • Groudon greatly aids victory against Rock Blast and Ancient Power sets

Dodging strategy

  • Hydro Pump and Rock Blast can snuff out a Solar Beam before it hits
  • At low levels (≤30), should dodge a few Ancient Power to not wipe out
  • If failing: attempt fewer dodges if timing out, more dodges if fainting out

Counters

Note: "Good" movesets are not necessarily viable at the level indicated.
