Ground-type Pokémon have powers and abilities related to control of ground and earth. Ground-type Pokémon are afraid of water, like Rock-type Pokémon, unless they are Water type. Many Ground Pokémon are also partially Rock type.
These Pokémon are normally found in caves or rocky terrains, with the exceptions of some dual typed Pokémon. One bad thing about them is that they can't normally come off the ground, such as Diglett and Dugtrio, even though they are pretty good combatants when they are below the Earth's surface. They have powerful moves such as Earthquake and Fissure.
