First, I'll repost the Doomsday I posted in the other thread:
I used the hips, thighs and boots from a NECA Bullestorm figure. I was going to paint them green, but I kinda like the brown now. The biceps are from Parasite. Once I swapped them out I realized that his forearms were too short, so I added gauntlets using the legs of some poor DCD figure from the fodder bin.
I chopped most of the spikes off his elbows, knees and back and repurposed them on his shoulders like the Injustice design. Then I painted all of his bones pale gray and gave them a black wash. Again, gonna add some to his chest as that's looking a little manicured by comparison.
