Ka D'Argo (called simply D'Argo), played by Anthony Simcoe, is a Luxan warrior who was imprisoned aboard the Leviathan Moya by the Peacekeepers after being convicted (falsely) of killing his Sebacean wife Lo'Laan in a fit of Luxan Hyper-Rage. During his time as a prisoner, the Peacekeepers shackled D'Argo in his cell with heavy chains attached to a pair of metal hooks surgically implanted around his collarbones to keep him under control despite his strength. He later escaped (along with Rygel and Zhaan). As a Luxan warrior, D'Argo carries a weapon known as a Qualta Blade, a heavy broadsword that can transform into a Qualta Rifle. His personality in Season 1 was paranoid and ill-tempered against his friends (in the fourth episode, D'Argo puts on a Tavlek gauntlet that injects a stimulant so "stimulating" his personality that D'Argo attempted to take command of Moya and kill all those who stand against him). He has a powerful, fast tongue that he can use to attack in a manner similar to that of a frog or chameleon. The tip can inject an "adaptive" venom which renders the target unconscious without killing them.
