As I have mentioned before, the Dungeons & Dragons Cartoon is my all time favorite, and it's because of guys like this.
Considering he was only in one episode, you can guess how well that worked out for him.
But, Kelek was iconic enough to be one of the action figures that TSR made in the 80's. There were a few others that made it into the cartoon as well.
For Kelek, I used the Heroclix Mandarin and some green stuff and plastic to make his beard and funky collar.
(Unicorn horns not included.)
