|“||I had a baby brother! I had a little baby brother! And he was perfect! Perfect in every way!||”|
– Rictus Erectus
Immortan Joe's fourth heir was an unborn, unnamed child carried by The Splendid Angharad.
Splendid was carrying the child. She was seven or eight months pregnant when Imperator Furiosa helped smuggle her and the rest of the Five Wives out of the Citadel. During the pursuit, she used her body and that of her baby to keep Immortan Joe from firing on the group. In the battle, she falls from the War Rig. According to Max ,"She went under the wheels". Splendid is fatally injured, and while dying the child is removed via C-section by the Organic Mechanic in an effort to save its life, but it was already too late. In the Mechanic's words, the child was "perfect".
