This is fantastic and so retro-cool!

I like it!

Thanks for the info and explanation. This figure is awesome.

Very, very cool (or hot). Looks authentic to the original toyline and actually I enjoyed his appearance so much that I did want a figure of him back then but was disappointed there wasn't one. After re-watching the whole series last year I still like this character. Still find him somewhat unsettling too. Hm, you've used the Mumm-Ra torso and head that has the ring bit on the back, does that mean his eyes light up? Also, Snarf arms as the tail? I'm not seeing them. :O
Oh and the ThunderCats wikia spells his name as 'Enflamer' but I'm not really sure which is correct. :P

Yeah the eyes still light up, but due to the middle being painted over it's just the outer circumference that emits light.

Snarfs arms were used as I had them left after using the tail for my reptilian soldier custom. The arms were fitted where the legs would usually attach to the torso. Then I used them as a frame to built the lower portion of the figure and have it articulated. There are some WIP pictures I couldn't fit into the 3 pic limit here that you can check out on the thundercatslair forums in the customs section

The spelling of the name I used is taken from the production art used on the show. I can't link to the image but Google Thundercats production art to see it. There are some great images of the other side characters too.
