That scag and his floozie, they're gonna die!Roop
Roop was one of the MFP officers. Along with Charlie, he commandeered the "The Big Bopper," one of the MFP patrol vehicles. He was very aggressive, shouting at Charlie on many occasions during their part in the pursuit of The Nightrider.
According to the revised timeline presented in 2015 Mad Max prequel comic books, him along with Charlie and the other MFP members became marauders after the Apocalypse with the disbandment of the Main Force Patrol. The crew attacked The People Eater's tribe before he was spotted by Colonel Joe Moore.
