Thank you Palitoy for creating such a concept. A skeleton robot, how great is that? Of course they gave him no back story, so other than that he's a Red Shadow he's a blank slate, but you still can't go wrong with the core concept. The original Skeletron figure always stuck with me, but the weird proportions and the limited articulation kept me from seeking one out. When Star Wars Episode 2 came out, I realized the Grievous figure would be an excellent starting point for Skeletron, and so I made one. But my skills weren't where they are now when I made him, and I couldn't find a head I really liked, so I was never quite satisfied. I started a new one with the intention of simply duplicating my original recipe, but with added articulation (elbows, hips, and ankles) but a new, much better head happened along and now I have a Skeletron I'm very happy with.
