Yamask
The Spirit Pokémon
Type: Ghost
Official Registration #: 562
Entry: A ghost-type pokémon prevalent in the graveyards and ruins of Unova. It is said that yamask are the restless spirits of those close to pokémon, transformed for eternity into pokémon forms. The mask they carry, then, are the faces they once possessed, which are their final token of their lives as humans, as well as a constant reminder of their eternal curse. Then again, yamask can also communicate with other pokémon and wield pokémon powers, so … the author, for one, could probably deal with eternal damnation to the moral plane and the existential horror involved with the loss of identity.
Cofagrigus
The Coffin Pokémon
Type: Ghost
Official Registration #: 563
Entry: The evolved form of yamask, by battle experience. Upon evolution, yamask take up residence within a golden, coffin-like shell. From this shell, they reach out with their four ghostly arms to snatch up hapless wanderers and graverobbers and pull them into their bodies. This is just one thing cofagrigus is famous for. The other thing popularly known about this pokémon is the fact that whoever named it clearly did so with the conscious intent of creating a massive headache for those of us who deal with adult content filter systems … such as, say, for example, administrators of digital transportation systems.
