Kufbrug was a Gamorrean female who served as the clan matron for the Bolgoink clan. Her impressive size, reaching almost two meters tall and exceeding two hundred kilograms, defined her. She adorned her long, greenish-brown hair with braids and was notable for the numerous morrts covering her body. These features, coupled with her large brood, made her exceptionally desirable within Gamorrean society.
Initially, she was wedded to Vrokk, the clan's warlord, and Gundruk was among her older daughters. Kufbrug harbored affection for Guth. Following Vrokk's demise and the false accusation against Guth, which threatened his life, Kufbrug experienced a period of despair. Her spirits were revived when Callista Ming enlisted her aid in confronting the kheilwar responsible for Vrokk's death. Together, they battled the insect throughout the night, ultimately slaying it and exonerating Guth. Subsequently, Kufbrug and Guth entered into marriage.
Kufbrug displayed an unusual level of intelligence for a typical Gamorrean, demonstrating the ability to discern deceit and formulate backup plans, which astonished Callista Ming. Despite being viewed as a highly attractive and authoritative figure, she also possessed a sentimental nature, succumbing to depression when she feared the loss of her beloved Guth.
