Way back in the 1980's, there was a cartoon show called Dungeons and Dragons, based very very loosely on the RPG of the same name.
In that show there was an evil warrior/bounty hunter named Warduke who, to my knowledge appeared in a single episode only.
In a toy-range associated with the TV-show there was also an action figure of Warduke.
Just like Boba Fett, this guy became an instant fan-favourite despite his minute amount screen time and (likely) because of his cool looks.
I kit-bashed a miniature of him, using 3 different plastic Chaos Warriors from Warhammer Fantasy Battles, a Chaos Marauder for the same game and the "wings" on his helmet comes from a Night Lords helmet by Forgeworld, intended for Warhammer 40000.
