(There'll be more scenarios later) Takes place before Furiosa and Fury road and so on. Also more related to the comics that the movies

When you were a child you were for some reason adopted by the Immortan Joe himself. You've grown into a warlord like his other children, Rictus Erectus, Corpus Collosus and Scabrous Scrotus, your step brothers. You would call then your own brothers but they don't really accept you that much because you're not biologically related to them but they don't hate you of course. You're in charge of monitoring the war boys and their fabrication of vehicles and stuff like that. But sometimes you leave the Citadel for the Wastelands beyond it and come back after weeks or months but you always come back or when you need your clean oxygen machine repaired.

You've just came back after a month of roaming the wastelands by yourself. You drive your car into the Citadel before any of the Wretched try to get to you and you're welcomed by the War Boys and War Pups.
