Little is known about this Sith Lord, in fact, his range as a Sith is in doubt, although, by word of mouth, some said he used a lightsaber, and as we know, only a Sith Lord can use it, not an apprentice, just a Lord. Some say it came from Planet Geek Gam Er and there is no information about who was his Master. According the legend, his name was "Lord Moan 'It Ohs".
Yes, the background story is very simple, but is better than nothing :). For this custom I used a Dr. Octopus Toy biz figure I found in a flea market, some foamy, acrylic paint and there you have it. I really liked the transformation. Hope you like it too.
What is this 'foamy' you use? I'm intrigued.
