Dr. Mundo Build
the Madman of Zaun
Utterly mad, tragically homicidal, and horrifyingly purple, Dr. Mundo is what keeps many of Zaun's citizens indoors on particularly dark nights. Now a self-proclaimed physician, he was once a patient of Zaun's most infamous asylum. After "curing" the entire staff, Dr. Mundo established his practice in the empty wards that once treated him and began mimicking the highly unethical procedures he had so often experienced himself. With a full cabinet of medicines and zero medical knowledge, he now makes himself more monstrous with each injection and terrifies the hapless "patients" who wander near his office.
