Walon Vau is another character from the Republic Commando series by Karen Traviss.
Walon acts as a foil for Kal throughout the series, so the two seemed a natural choice to make as a set.
I tried to make him tall and gaunt, to match the "cadaverous" description he's given, and attempted to make his figure more visually interesting than a mando sculpt just dipped in black paint, going for a gray jumpsuit beneath the armor plates, and detailing with brown and gunmetal.
