Water and Rock types: weaknesses, resistances and Pokémon

Water and Rock Pokémon take quadruple damage from Grass moves, take double damage from Electric, Fighting and Ground moves and resist Fire, Normal, Ice, Poison and Flying moves.

The balance is even: 4 weaknesses and 5 resistances or immunities.

Water moves are super effective against Fire, Ground and Rock and not very effective against Water, Grass and Dragon. Rock moves are super effective against Fire, Ice, Flying and Bug and not very effective against Fighting, Ground and Steel.

To beat these Pokémon, your best pick is Grass moves. Avoid Fire, Normal, Ice and Poison moves, which deal little or no damage.

There are 11 Pokémon with this combination, such as Omanyte, Omastar, Kabuto and Kabutops.
