In the science fiction television series "Farscape", Ka D'Argo is a Luxan warrior who was accused of killing his Sebacean wife and was subsequently imprisoned upon Moya. His typical reaction to any situation is to shoot first. He rarely worries about asking questions.

D'Argo has trouble making friends, as he doesn't trust others easily. He has an uneasy comraderie with Crichton and they constantly bicker and argue, but their banter is more like that between brothers.

Luxans suffer from a condition known as Hyper-Rage, and D'Argo is no exception. When this condition sets in, it can usually only be stopped by massive amounts of destruction, which D'Argo is very good at.

D'Argo prides himself as a skilled warrior, however he really only wins about 50% of his battles. He is a strong ally to the crew on Moya, respects Aeryn as a fellow warrior, loves Chiana, has a deep spiritual respect for Zhaan, and would like to get rid of Rygel at the first available opportunity.
