Dennis Fling was a male resident of the Capitol and a student of the Academy. He was one of 24 top-performing seniors at the Academy selected to be a mentor for the 10th Hunger Games. He was assigned the male tribute from District 5, Hy.
Things did not turn out well for him, as his tribute died of complications from asthma the night before the games even began.
- His name appears on the list of mentors from the Academy shown throughout The Ballad of Songbirds and Snakes and he does not have any lines in the book.
