Head: Motu Plunder with salacious crumb's eyes. This head is pretty perfect for a toony design similar to the comic art. Unfortunately he's a different scale.(6 in Jaxxon?hmmm) If you're familiar with shrink molding, you could theoretically make a 3 3/4" cast.
Arms/torso: Clone wars cold gear Anakin. Greedo would work well too.
Legs upper: Scanning trooper
Legs lower: Greedo.
Gloves: Mcquarrie Snowtrooper
Boots: OTC cloud car pilot.
Shoulder armor: Part of Anakin's bubble space helmet, with some parts from a Doctor Who spaceman and Mr Freeze.
Back later with a recipe for version 2.
