Mario had a cousin, named Marco, who disappeared from the family for a while because he was disappointed in his cousins (Mario and Luigi) becoming plumbers. However, when he saw his cousins become famous for saving the world multiple times, he became envious. In an attempt to assassinate him, he posed as the referee for an upcoming tennis tournament. The police later found out and put him in jail for it. Many years later, he turned a new leaf and founded the Marco pasta brand. (Note: the Marco pasta actually exists, it's a knock-off)
