The richly imagined world of Mad Max boasts plenty of memorable villains, but the desolate landscape of the Wasteland could also believably house many other classic foes. While the likes of Immortan Joe, Lord Humungus, and Rictus Erectus make Mad Max a fascinatingly varied and frightening franchise, there are many other characters who would fit right in as villains in this world created by George Miller. While the Mad Max series boasts several sequels, if a crossover ever happened, these would be ideal candidates for inclusion.
