The Purple Ninja
The Purple Ninja is the greatest Demon Hunter of them all. He is an enigma, wrapped in a mystery, draped in violet gi.
The Purple Ninja is a character who appears in all of the movies produced by Dead Gentlemen Productions. In every film he is credited as playing himself. Apparently, The Purple Ninja is actually played by Nathan Rice when speaking, who appears in each of the DGP films.
Purple Ninja's Film Credits
In Demon Hunters, he appears as "The Greatest Hunter of All Time", and confronts Duamerthrax the Indestructible, efficiently defeating the demon in personal combat, but the demon, being indestructible, kills the Purple Ninja with a surprise attack, breaking his spine. The stunt double for the Purple Ninja in Demon Hunters was played by Victor Prinsen.
When Duamerthrax returns to life in Demon Hunters: Dead Camper Lake, the Purple Ninja also returns, but the demon, presumably not wanting another butt-whooping, quickly and ruthlessly tears him in two (offscreen).
The Purple Ninja can also be seen during the battle with the bandits in The Gamers, where the Bandit King kills him in the background as the main characters fight. It is unclear whether Nathan Rice plays this incarnation but it should be noted they do not appear together onscreen, hmm).
In The Gamers: Dorkness Rising, the Purple Ninja is one of the protagonists (along with the mysterious Orange Ninja and a crew of Pirates) of the Pizzajitsu Game that Kevin Lodge and Johanna are enjoying. This incarnation of the Purple Ninja is not played by Nathan Rice and remains uncredited (or could be the real Purple Ninja!).
His story is revealed (more or less) in the Demon Hunters Corebook (in which there are many quotations of this mysterious warrior, and in which it's revealed that he really likes Avril Lavigne) and he also makes a brief appearance in the included Orientation Video DVD.
Behind the Scenes
The concept and origins of the Purple Ninja are (ahem) unknown and for the sake of a family friendly wiki, most probably should be kept that way.
