Kevin is the Captain of the American team participating in the US/Japan Goodwill Games in the anime. He appears in Japan weeks before the tournament to settle a rival feud that began with his father, George Smith, and Ryoma's father, Echizen Nanjirou.

Kevin first challenges members of tennis teams in the Tokyo area as he searches for Ryoma (who was attending the Junior Invitational Camp). Kevin plays a highly destructive form of tennis and injures other players, most notably Akutsu Jin of Yamabuki.
