World Champ is a boxing video game for the NES. There are three modes the player can choose from: "Ranking", "1P vs 2P", and "Tournament". The last two are two-player modes where both players can square off against each other. Ranking is the single-player mode where the player competes in matches while building up their boxer's stats. As the game progresses, the player goes up the weight classes from Welterweight to Heavyweight.
DrD2k9 here wins the championship in record time by pummeling all of his opponents into submission and giving them no chance to fight back.
