So I FINALLY finished this commission. All in all, I used the Hulkbuster fig, 5) 3-3/4" War Machine Movie series figs, 2) 3-3/4" Comic Series figs, Sigma 6 Destro and Duke, GI Joe Steel Marauder, ROTF Sideswipe, and a 6" Mark VI head. Tony Stark head was removed and replaced with 6" Iron Man head that I added some styrene to for a more War Machine-ish look. Shoulder pads were moved to knees, and forearm guards were removed. Five gatling guns and conveyors on the right forearm. Two gatlings on left bicep. Three guns on each hip. Destro's gun (with added firepower) attaches to left forearm with magnets. Duke's railgun on right shoulder (with cell phone car charger cord attached to back). Steel Marauder's missile launcher on left shoulder. Steel Marauder's shoulders and a few other parts were cannibalized for his backpack. The steel marauder feet and hacked up legs, ROTF Sideswipe's shocks, and styrene were used for the feet. I think that about covers the mods. Primed with flat black. Drybrushed with a few shades of grey, steel, and silver chrome enamels. Highlights are red, orange, yellow, white, blue, and copper. I'm beyond happy with how he turned out, but believe you me, I can't wait to ship him away forever. As always, thanks for looking!
