If you haven't already checked out Onell Design's "Glyos System", do it now! [link]
They're cool little 2-inch figures with interchangeable pieces so you can build amazing designs or just have the characters chilling in your pocket.
This is the character Sarvos, made from an Iron Man 2 comic series figure and parts from Matt's Sarvos (head, hands, feet). The body armor was sculpted on using Aves Apoxie Sculpt and he was given some plug-on Phase Arm modules made from fodder and the Glyos system parts.
