Immortan Joe, formerly known as Colonel Joe Moore – was a veteran of the Oil Wars and a hero of the Water Wars. He formed a biker gang terrorizing the people after the fall.
With each battle the gang grew stronger by slaughtering the leaders of other gangs and taking the women. With that, his idea of bringing back society willingly took a dark turn. Eventually he and his gang entered the wasteland, where he would learn about a massive aquifer plant later known as The Citadel.
