Nux

Nux is one of the main characters in Mad Max: Fury Road, portrayed by Nicholas Hoult. He is a member of Immortan Joe's army of War Boys and lives in the settlement known as The Citadel, but later allies himself with Max Rockatansky and Imperator Furiosa after feeling responsible for Angharad's death.

Nux was a War Pup that was brought up as a mechanic in The Citadel, a "Black Thumb", after he was taken in by the War Boys. His family was unusual as they stayed together out of love and refused to sell one another out for a better life. When his mother died of illness and his father was sent away to perform dangerous work, however, Nux was left alone and caught the eye of the Citadel. He never saw his father again.

Fanatically believing in the Cult of the V8, the surrogate fatherhood of Immortan Joe, and all things mechanical he desperately wanted to get as close as possible to becoming a machine himself. His religious devotion is represented by engine block scarification on his chest and his desire to "die historic on the Fury Road", which is the desire of most War Boys due to the fact they have "half lives". His name was changed to "Nux" because he was a "hard nut to crack." After coming of age and being lucky enough to live this long he turned into a War Boy and became a driver for Immortan Joe, who he, like the other War Boys, views as a god.

Nux - much like the rest of the War Boys - is inherently sick and on the brink of dying because of the environment he's been living in. The first time we see him he's getting a blood transfusion from Max - whom he calls his 'blood bag'. He also uses Max as an adrenaline donor while he's driving. On his neck he's got two deadly tumors that he affectionately calls "Larry & Barry". Nux's life is almost over for him but then he sees Furiosas' escape as the perfect opportunity to prove his devotion to Immortan Joe and entering afterlife in Valhalla. He sprays chrome paint in his mouth to show his worship for mechanical things and to get high before committing suicide by flooding his vehicle with gasoline and ramming it into Furiosa's War Rig. His plan fails.

Nux's mentality is initially of that of a child's; he is driven by impulse, desperation and absolute religious devotion. With time away from Immortan Joe and the War Boys, Nux's personality quickly matures.
