Ground type

Ground is one of the strongest types offensively: it is super-effective against five other types (as is Fighting) and Earthquake is one of the strongest moves in the game with power and accuracy both 100. In the first few generations many Ground type Pokémon were dual Rock types, lumbering them with 4x Grass and Water disadvantages; most newer Pokémon introduced avoid this now. In Generations 1-3, all Ground type moves were categorized as Physical.
