This custom began with a head I found on eBay (one of a few I got on that site - you can see pics of a few of my custom orcs below).
Initially, I was going to make him a wounded orc warrior, but as I started working with the head, this character came out instead. I imagine him as a world-weary orc who has turned away from the life of battle and bloodshed that his brethren embrace. Instead he travels the realm seeking peace and redemption and bringing justice to those who do evil. He carries with him relics from his travels, including weapons he ma2y have found in other realities or planes of existance! For me, this character is kind of the Doctor Who of the orc world!
As mentioned, the head is a custom from eBay that I painted. The orc body parts are from Unkann, while the chest is an orc legion builder, the loin is from a knight builder set, his shoulder pad is from the Barbarian kit, and the other armor pieces are from a Volligar. I added some paint to weather the armor pieces. The coat is from a WWE Undertaker figure. It had a hood that I cut off and I painted the coat to further weather it.
For his weapons, I wanted him to have a hodge-podge of pieces. The staff is from a Gothitropolis raven, his gun is a Star Wars Black Series Tusken Raider, his bow is from Articulated Icons, and his quiver/holster is from a Lords of the Rings toy.
