This figure was made as part of a series of samurai-themed figures I did that I called "Mythic Shoguns"
You can read this character's story on my Instagram page.
There are actually a pair of skeleton samurai shown in these pics - the one with 4 arms is one I made for my own collection while the other one was sold. In both cases these started with a Skeleton Solider figure from the Advent of Decay wave. The armor and weapons are from the Articulated Icons series. The armor and helmet come from the Temple Guardian figure, while the spear and bat weapons and the head crest on the 4-armed version come from a Fumetsu figure. The entire figure was given a repaint to add some grim and muck to create the undead look I wanted.
