I've always liked Vengeance, and I hope he gets to appear in a movie or show at some point. He was an irritating piece to make since his colors and design varied constantly. I finally just used the Marvel Legends figure as my general reference. I'm still aiming to get to a Danny Ketch Ghost Rider design at some point, as well.

Swapped out the upper legs for Hyperion, and the lower legs from Wonder Man. Cut down the gloves and sculpted up the spikes on the hands and the bone wraps. Head was a very old cast with the flames sculpted on. Heavily sanded down the entire torso and smoothed it over with sculpt. Then sculpted on the bone straps and bone belt, flames around the neck, and ribs. Shoulder spikes were toothpicks, with some extra sculpt to hold them in place. Also sculpted up the boots and spikes. From there, a full repaint, and all done!
