Immortan Joe is the main antagonist of the 2015 Warner Bros. film Mad Max: Fury Road. He is the tyrannical and ruthless ruler of the Cult of the V8, as well as the most powerful of the warlords controlling the wastelands.
He rules the wasteland from his Citadel, keeping his citizenry in line through use of the aquifer concealed under his fortress, encouraging them to worship him as a messiah. Old and diseased, Joe is now determined to ensure that his kingdom remains intact long after his death, and to that end, he keeps a harem of wives captive, hoping to produce a viable heir through their repeated rape. When his wives are freed by Joe's Imperator Furiosa, Joe and the War Boys set out to recapture them.
He was portrayed by the late Hugh Keays-Byrne, who previously portrayed Toecutter in the very first Mad Max in 1979.
