NOTE: The 2008 Spirit of King Grayskull figure is not considered an official part of the Masters of the Universe Classics line. According to the Matty Collector website:
"To help celebrate the return of Masters of the Universe® toys to collector's shelves, Mattel created a special variant of their San Diego Comic Con exclusive King Grayskull™ action figure as a "Spirit" that will forever live in the walls of his castle. Only two editions of this all-clear version of King Grayskull™ were made for the public. One was raffled off at 2008 San Deigo Comic Con, the second was auctioned for charity at the 2008 Dream Halloween event."
Former Matty Collector Brand Manager Scott Neitlich subsequently stated: "The 2008 employee fig is not part of the official line. Hence left off the poster too. The 2015 release was meant to be a way to deliver this figure officially in the line."
In addition to the two charity figures, a small handful of these were given to Mattel employees.
