The Coma the Doof Warrior is such a cool idea. You've got your army of religious zealot soldiers in their war-cars. Most fighting is close in, with thrown weapons, crossbows, or melee. It's not a shooting war, it's more like ancient cattle raiders or something. So how do you announce your arrival, cow your enemies, and hype up your troops? A gigantic drum truck with a blind, insane guitarist shredding and unleashing fire!

It'd such a great illustration of how insane the world has become. And, contrary to what many people think, that kind of theatricality and spectacle is done by warlords and irregular armies in the real world. The Liberian civil war is famous for being a nightmare fever dream, with cross dressing soldiers, naked killers, magicians and wizards. Just utterly bizarre and horrifying. Mad Max isn't really fantasy, it's just an exaggeration of things that happen in the real world.

The Doof Warrior also continues the theme of disabled people being included in society without question or remark. He appears to have no eyes, possibly a condition he had at birth. No one gives a shit. He shreds, he's part of the warband, and the War Boys built him an entire goddamn shrine to metal.
