Ghost

The Ghost-type is one of the fifteen elemental types introduced in the first generation of Pokémon. As one might expect, Ghost-type Pokémon are quite elusive and mostly gas-based organisms haunting the Pokémon world. They are extremely rare to encounter, too.

It is to note that before Generation 4, all damaging Ghost-type moves were categorized into physical attacks, while afterward being split up into the special and status categories too – depending on the move.
