What is ground type weak to?

Ground type Pokémon are weak to several other types in the Pokémon game series, including:

1. Water: Water attacks deal 2x damage to Ground types and can easily take them down.

2. Grass: Grass also deal 2x damage to Ground types. This can make Grass type Pokémon a great counter against Ground type Pokémon.

3. Ice: Ice attacks are also weak against Ground types, dealing 2x damage and making Ice type Pokémon a suitable option to take on the Ground types.

4. Fighting: Fighting type attacks deal normal damage to Ground types, but Ground types cannot hit Fighting types with Normal and Flying type moves, making Fighting type Pokémon a good choice to counter Ground types.

5. Steel: Steel types are immune to Ground type attacks and can resist other types of moves, which makes them a strong option to fight Ground types.

Overall, Ground type Pokémon have a substantial weakness to water, grass, ice, fighting and steel types, and players should carefully consider these strengths and weaknesses when building their teams.
