Marty Hansen (aka TheGodBeast) has revealed photos (and details) about the Kabuto Mushi MKII prototypes. This is the UV resistant urethane metallic green/gold iridescent Kabuto Mushi MKII prototype (there are photos of the gray resin high polish Kabuto Mushi MKII prototype on Marty's blog - linked above). This was a collab with Matt Doughty from Onell Design.
