One of the many incredible things about the Pokémon franchise is that it's always evolving. With hundreds of different Pokémon across 18 type categories, there's an abundance of creatures to love.

As the second rarest Pokémon type after Ice, Ghost-type Pokémon are hard to catch and known to be quite mischievous. They're often associated with the afterlife or cemeteries, which only makes the Pokémon seem creepier. There are only fourteen pure Ghost-type Pokémon in the entire Pokédex so far, all with varying degrees of strength — and they're all quite formidable in their own ways.
