I really wanted a Dormammu figure for ages, but neither Toybiz or Hasbro went anywhere near him.
I started off using the ML Legendary Riders Series Vengeance and cut off his leather jacket. To my dismay he didn't have anything even close to a proper torso underneath, so I sculpted it from scratch using Milliput. At least all that life drawing at Art School wasn't completely wasted.
I carved off the spikes from the knuckles and boots, and also the boney wristbands. I slowly carved away at the face till I was happy with the shape and expression, and smoothed it over with milliput. I extended his head flame so it engulfed his head using cut up pieces of one of Iron Fist's flames.
His 'loincloth' was cut from foam rubber sheets and layered up, and the skirt from the bottom half of the coat of a DC Elsewords The Bat figure (you'll see that figure being put to good use in 2 more customs I'll upload later). I managed to reuse Vengeance's ribs for his collar and the flame in his hand came from a Pumpkin Bomb that I whittled away (which took forever and almost cost me a finger, hence why I never made one for the other hand).
The figure was painted completely black except for the flames, with purple drybrushing on the legs, arms & torso, yellow and red drybrushing on the flames, and several shades of red drybrushed on the loincloth. I painted his mouth and eyes bright yellow and covered his face in thin yellow and red lines, congregating aroung the top of the mouth and eyebrows.
It was a pretty big job, but it's now one of my favourite figures, and a character that was sorely missing from the Marvel Legends line. I'd quite like to attempt a 12" BAF sized version using an Icon's Human Torch at some point in the future, but for now I'm happy with having a 6" Lord of Chaos.
