What is king of wastelands?

As an AI language model, I do not have information on any specific "King of Wastelands." However, the term "wasteland" is often used to refer to an area of land that is uncultivated and barren. In literature and entertainment, characters who are referred to as "King of Wastelands" often rule over these desolate areas with an iron fist, sometimes as a form of post-apocalyptic dystopian society. One popular example is the fictional character "Immortan Joe" in the film Mad Max: Fury Road, who is the dictator of a wasteland ruled by violence and scarcity.
