Whew. What a trial. Metron himself wasn't too bad, but it as pure agony to work out the Mobius chair. Wanted it to be properly sized, and nothing I was finding was fitting that. Until I came across some GI Joe vehicle chair in a fodder box. It was large enough to work as a base. Used a ton of fixit sculpt as the base to build off of. It's more solid than kneadatite, so it worked a lot better to add bulk. Added kneadatite around that for the smoother look. I ended up basing the design of the chair more on the 6" release, and the design for Metron himself on one of his many over the years. Only one I could find good angles on. Head was from a GI Joe Wetsuit. A bit of a trial, but I'm quite happy with the final result.
