Necreon the zombie pokemon

Necreon is the ghost type evolution of Eevee.
The first known Necreon was discovered wild in a cemetery and it is believed an eevee must be around the deceased in order to trigger this evolution. Because of this, when a Necreon is spotted nowhere near a grave site, police will investigate the area in search of a missing body or possible murder case.
Necreon have a second spirit like form that renders them intangible like their ghost pokemon kin. Their bones are incredibly strong and near unbreakable, particularly in the tail. The bone tail can move quite fast and can deal a dangerous blow.... especially the sharp edged tip.
Necreon's skin does not receive a proper blood supply, thus why it gives off the appearance of rotting flesh.
