Wullthaug is one of my more recent MOC's, whose back-story takes place within the BIONICLE Universe. Wullthaug is a member of the mysterious "Threkshee" species, and is known for his personal quest of collecting Great and Noble Kanohi masks. Wullthaug is famous and in some cases infamous for designing what he calls "the Kanohi Blade," a weapon that allows him to use the powers of any Great or Noble Kanohi mask he equips the Kanohi Blade with. Thus, the more masks he collects, the more powerful he becomes. He has served alongside the Order of Mata Nui in many operations, but his most famous mission was his partnership with OoMN defector Toa Onnyx against the rogue Skakdi organization "Black Vulga."
