Darkrai

Darkrai appeared in 2006 video game called Pokémon Diamond & Pearl. Darkrai is a Pitch-Black Pokémon. Darkrai defends its territory by sending intruders into a deep sleep, where they are tormented by terrible nightmares.

The top of its body is connected to the lower half by a tiny waist, giving it an hourglass-shaped figure. It has a red spiky growth around its neck and a long white mane flows from its head, obscuring one of its blue eyes. Its thin arms have three claws each, with three spiky protrusions above each elbow. Its shoulders also have long tatters and it appears to be wearing an old ripped cloak or dress. It is able to extend stilt-like extensions to use as "legs".

Darkrai resembles a ghost or a haunted spirit but it is interesting to note that, despite it's design, Darkrai is not a Ghost type, instead being a pure Dark type.
