This is a reference to him being the best player in the same sport back in Resort (when it was called Swordplay). His appearance has been updated on the Switch; now his skin is darker and some of his facial features have slightly different positions. In Nintendo Switch Sports, he wears the Official Gear (Purple) clothing. His in-game title is "Legend."

Trivia

 * In the background of the Boxing training gym, some newspaper clippings can be found of an implied younger version of Matt fighting as a professional boxer. Text can be seen saying "Go Champ!", "K.O.!", and "LEGEND." The images feature an implied younger version of Andy and an indistinguishable male Mii.
