Mad Max Fury Road's 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. His gang included henchmen dubbed Major Kalashnikov and a strategist: Deepdog. 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. - Wikipedia
Joe is an older man with a stocky build, with long white hair and piercing blue eyes. His health is failing as evident from the respirator mask (decorated with horse teeth to resemble a skeletal jaw) which pumps clean air into his body. This mask is connected to a large breathing apparatus worn on his shoulders. Joe is covered from head to toe in white powder which eases his pain, giving him a ghostly presence. He wears a Plexiglas armor, which is adorned with several service medals and molded to give him a muscular appearance. His costume is designed to both aid his failing body and hide it from his enemies.
I think artist Adlectus1/6's custom figure embodies the character perfectly that was in the movie. I just wish this had been mass produced. Check out Adlectus1/6 Facebook for more cool and interesting customs.
