Scorpius (Farscape)

Scorpius is a central character and primary antagonist in the space opera TV series, Farscape. He is a hybrid of the reptilian Scarran race and the humanoid Sebacean race and a commander in the Peacekeepers, a primarily Sebacean military organization. Abused in his childhood by his Scarran keeper, Scorpius has grown a deep hatred for all Scarrans and seeks their complete annihilation. He is also obsessed with acquiring wormhole weapon technology which he believes to be the key to his goal of destroying the Scarran forces.

Scorpius's goal throughout most of the series is to steal the secret wormhole knowledge locked away in the mind of series protagonist, John Crichton.

While he is portrayed as a straight villain in the first two seasons, over the course of seasons three and four he ends up evolving into more of an anti-hero, eventually joining the crew of Moya. However, even then, he has a mostly strained relationship with Crichton, who continues to view him as a nemesis.
