Mario Mugione is an Italian-American lawyer who is in his mid-20s, and the twin of Luigi Mugione. He lives in Washington, DC as a lawyer. Curly dark hair, tall build and fairly muscular. He likes the outdoors and sports like pickleball and skiing. He also enjoys lifting. Like his brother, he is very academic and smart, and reads a lot, especially history and biographies about US presidents. He is conscientious and cares about fairness and justice, which is why he was attracted to Law School and became a lawyer. His brother Luigi and him are very close, though unlike his brother, he does not suffer from chronic back pain and never had surgery. He has been devastated by his brother's ongoing health issues, and is the only one who has been talking to his brother about his entire journey after back surgery. He is protective as the older twin, and will do anything in his power to help his brother, including getting out of any legal issues his brother may face.
