On April 11, 1974, Guts fought WBC Champion Rodolfo Gato González in Tokyo. González had a record of 59-5-0 (50KOs) going into the fight, as opposed to Guts' rather pathetic record of 26-11-6 (14KOs). Few expected Guts to win, but Guts fought toe-to-toe with the champion, getting a knockout win in the 8th round. Guts credited his win with being able to prepare for three extra months (González was bitten by a spider before the fight, moving the date back three months), which he used to pack on extra stamina for the fight. Guts was re-introduced to González 32 years later on a Japanese television show, where he learned that he and Gonzalez bore an uncanny number of similarities, including being born in a poor household, and succeeding as an actor after retiring from boxing as former world champions.
