Mundo, short for Dr. Mundo, is a Corporate Mastermind/Mad Scientist in the Runeterra city of Zaun. He prides himself on his lack of restrictions when electing to perform an action. Often times, he takes great enjoyment in performing these actions, and will not hesitate to announce said enjoyment. Many people claim that bystanders go missing when around Mundo, but such a case has yet to be legally proven.
Mundo is defined as Mundo pleases.
