Syfy's science fiction western themed TV drama, Defiance, ran for three seasons from 2013 to 2015. Set in the post-apocalytpic Earth of 2046 which has been radically transformed with the arrival of a variety of extraterrestrial races, collectively called Votans, whose terraforming technology changed the geology, flora and fauna of the world. Defiance is a town built on the remains of St. Louis, Missouri, where humans and aliens try to coexist.
Lee Regesen's 'General Rahm Tak' was the main villain in the show's third season and he is a ruthless human-hating military leader from the Castithan race in the Votanis Collective (made up by the seven different alien races who escaped to Earth when their sun exploded).
And finally this costume below is worn by Conrad Coates as 'T'evgin', the leader of an eighth alien race, the Omec, who were once the overlords of the other seven races before they fled to Earth from their dying universe.
