originally titled is a 1987 boxing video game developed and published by Nintendo for the Nintendo Entertainment System (NES). Part of the Punch-Out!! series, it is an adaptation of the arcade video games Punch-Out!! (1984) and Super Punch-Out!! (1984). Differences from the arcades include the addition of undisputed world heavyweight champion Mike Tyson as the final boss. It received critical acclaim, and is retrospectively considered one of the greatest video games of all time. Gameplay Punch-Out!! features Little Mac, a young boxer fighting his way up through ranks of the World Video Boxing Association. After facing a series of colorful fictional opponents in three circuits and winning the championship in each, Little Mac enters a final "Dream Fight" against a highly skilled boxer. In the Gold Version, the final boss is Super Macho Man, who was also the final opponent in Super Punch-Out!!. Mike Tyson's Punch-Out!! features Mike Tyson, the real-life World Heavyweight Champion at the time. After the license to use Tyson expired, he was replaced by the fictional Mr. Dream. Little Mac has a limited repertoire compared to most of his opponents. His punches are limited to left and right jabs, left and right body blows, and a powerful uppercut. The uppercut can only be used once the player earns a star, which is typically accomplished by counter-punching the opponent directly before or after certain attacks are launched. The player can acquire up to three stars, but loses them whenever Mac is hit or knocked down. To defend, Mac can dodge left or right, duck, and block punches by putting up his guard. Little Mac has a heart counter, which decreases upon being hit, blocking a punch, or throwing a punch that the opponent dodges or blocks. When the counter decreases to zero, Little Mac temporarily turns different shades of pink and appears tired/exhausted, leaving the player unable to attack but still able to dodge, duck, and block. At this point, Mac can regain some hearts and his normal color palette only by avoiding the opponent's punches. He immediately loses all of his hearts upon being knocked down, but can regain some by getting up. A bout can end by knockout (KO), if a fighter is unable to get up within ten seconds after being knocked down; by technical knockout (TKO), if a fighter is knocked down three times in one round; or by decision, if the bout
