Mun Dae-Seong of Korea had been world heavyweight champion in 1999, but he had not placed at the world event since then, and did not compete at the 2000 Olympic Games. His top competition was felt to be Pascal Gentil of France, who had been European Champion as far back as 1994, had also won that event in 1999, and was runner-up in it earlier in 2004. After easily winning their first two matches, they met in the semi-final with Mun prevailing, 5-3. In the final, Mun met Alexandros Nikolaidis, who had no international record, but was the home crowd favorite. They were not much help to him as Moon won by knockout at 2:10 of the first round. Gentil went on to win the bronze medal.
