Once the player defeats the final opponent, the player will win the Heavyweight Belt, then defend it against the same characters that have already been beaten. Each successive time they are met, the opponents are harder and quicker. In order to win a bout, the player must knock out the opponent within one 3-minute round; failure to do so results in an automatic loss. A technical knockout is awarded if either fighter is knocked down three times, but the opponent will sometimes fail to rise after the first or second knockdown.
