Rocky Meredith hails from Pennsylvania and competes in the U-17 US Selection camp, one of twenty-four prospects aiming to become the 14th team member. He ultimately secures a position as an official USA representative for the U-17 World Cup. Standing 181 cm tall and weighing 74 kg, he possesses feminine facial features combined with a muscular build and distinctive tattoos on both upper arms; he plays tennis left-handed. His personality is initially polite, shown when he introduces himself to Ryoma Echizen after Ryoma defeats his teammate Maxwell, whom Rocky criticizes as a "Runaway Train." He respects team captain Ralph Rhinehart's leadership and abilities. While typically composed, he demonstrates assertiveness by intervening when Maxwell confronts Ryoma before the World Cup finals, reminding Maxwell of Ryoma's proven strength. Rocky's tennis background centers on the U-17 US Selection Camp. He faces Ryoma Echizen after Ryoma defeats other prospects, including C. Ridel and S. Truman. Though spectators consider them evenly matched, Rocky loses decisively when Ryoma employs his "Samurai" technique. Despite this loss, Rocky's persistent performance secures his position as a USA representative. During pre-tournament practice matches, Ralph orders him to play Ryoma again, and he surprisingly scores points against him. When Ryoma later leaves the U.S. team to rejoin Japan, Rocky states Ryoma may return anytime. Rocky's playing style is defined as a counter-puncher who utilizes power to overwhelm opponents. The official fanbook notes his wild fighting approach and physical tenacity, traits contributing to his representative selection after initial defeat. Ralph Rhinehart publicly praises his skills. Outside tennis, Rocky trained daily on the stairs of the Philadelphia Museum of Art to strengthen his legs and loins. His personal interests include favoring tomatoes and whoopie pie as food, listing Rambo as his preferred movie, and practicing flamenco as a non-tennis skill. Trivia indicates his name was initially translated as "Meledies" but officially confirmed as "Meredith" in December 2015. The character draws inspiration from Rocky Balboa, sharing traits like being a southpaw from Pennsylvania, with the surname referencing actor Burgess Meredith who portrayed Balboa’s coach.
