Effigeon-Pokemon concept

This is a concept picture of a possible Ghost type Eevee evolution or "eeveelutions". Since there's no Pokemon that evolves from any type to a ghost type I tried to come up with a decent explanation for this to happen ( at least I think it's decent ), to keep the spirit of the design.

P.D: The name comes from two words "effigia" ( that means likeness, ghost or shade ) in Latin and "eon" that is present in all the Eevee evolution names.

Update: The background has been changed to resemble the "who's that pokemon" game screen from the first season.
