The sabre bear is a deadly carnivore native to Qo'noS. It is most deadly when it is trapped without hope of escape.
General Martok was hunting sabre bear on Kang's Summit when he was captured by the Dominion in 2371. Martok would later liken the Maquis' losing struggle against the Cardassians and their new Dominion allies in 2373 to that of a trapped sabre bear. (DS9: "In Purgatory's Shadow", "Blaze of Glory")
