Image Description: Def is riding a converted land speeder. Puttying his robes was harder than I had anticipated.
The fluff was intended that to prove how tough he was, the boss decided to have one of his Doc's burn the skin on his face away and give him a more ferocious appearance. This was after taking a Necron Gauss Shell to the head, he still weilds the War Scythe of a vanquished Necron Lord...but now powered by Ork technology (this helps stand in for a Power Claw)
