Super simple custom!
I used the old style Minimates (the bigger ones) for this one, but it would be easy to make one out of the tiny guys. I sculpted the hair over the bare head and added some plastic strapping for his watch and his belt. I Dremmeled a hole for a peg on his back to attach the shotgun. The shotgun was made from a Chap Mei army figure's shotgun with model kit runners glued on for the double barrels. The chainsaw was made from bits and pieces of plastic. I painted him with acrylics and ZOWIE! Ash Minimate!
"Good, bad... I'm the guy with the gun."
I made a minimate ash as well too.
