Nux
A mechanic or "Black Thumb", Nux grew up as a War Boy in the Citadel in service of Immorten Joe, worshiping in Cult of the V8. When he misses his opportunity to 'die historic on the fury road', he finds a new way to live and discovers how to actually be a man.
Where is he from?
Nux is one of the characters in Mad Max: Fury Road, a movie that is so good at building it's world through what it shows you rather than what it tells you that you completely understand everything about this character, his life, and his world with barely any dialog or exposition at all. He's played by Nicholas Hoult, and is just one tiny part of a movie that basically schooled an entire genre.
