It's art by an artist /v/ stumbled upon recently who specializes in making REALLY FUCKING AWESOME human Pokeymons. Above is a rapidshare of all of his artwork. The files are named after their respective Pokemon and the colours are fixed (the op image may seem washed out to some, posted is a comparison picture from the edited rar).
P.S. In the zip, the one named Giratina is actually supposed to be Persian.
