It's just a charcoal suit with pinstripes, with a plum shirt & neon green tie to mirror the purple & green of his "Battle Suit". The Superman cape has been torn, burnt, and stepped on with dirt-covered boots, and red paint has been spattered on it, to simulate blood. The "brass knuckles" are simply layers of sheet styrene, epoxied together, shaped and painted. It was painted with gunmetal & spattered with red (again, to simulate blood). The "Kryptonite" are acrylic translucent green aquarium stones, that have been epoxied to each diveted "knuckle".
