Over 20 years ago, Goki was a test subject for giant experiments on Punk Hazard, but they failed. Goki and his colleagues were later recruited by Kaidou and joined the Beasts Pirates as “Numbers”.
Five days before the Fire Festival began, Goki arrived at Apoo Hakumai on Wano Country alongside other Numbers and Scratchmen.
On the day of the Fire Festival, the Beasts Pirates Pirates partied on Onigashima while Queen fueled the atmosphere. However, when chaos broke out caused by the enemy alliance, Goki, Juki and Jaki, who were drunk, went on a rampage and took collateral damage within their own ranks. In the process, Goki fell victim to many samurai, though he was without a chance when faced by the Straw Hats. After Zoro split his club, Luffy attacked Goki with a Gomu Gomu no-Kong Gun. Goki was unable to rise, after which Apoo mourned him.
