Best types to use against Grass/Rock

To beat a Grass/Rock Pokémon, use Ice, Fighting, Bug and Steel moves: they deal 2× damage. Do not waste turns on Normal (½×) and Electric (½×).

Grass/Rock and Rock/Grass are the same typing: in battle the order of a Pokémon's two types makes no difference, so a Rock/Grass search lands on this page too.

Going the other way, Grass and Rock moves between them hit Fire, Water, Ice, Ground, Flying, Bug and Rock super effectively, but Steel takes reduced or no damage from both.

3 Pokémon have the Grass/Rock typing: 2 species and 1 alternate form, first appearing in Generation 3 and spanning 2 generations to Generation 9.

The highest base stat total is Cornerstone Mask Ogerpon with 550; the average across the group is 467.
