Moon Isaac Jr. was a member of Gol D. Roger’s pirate gang.
During Roger’s lifetime, Moon Isaac Jr. was a corpulently built man with a very long nose and light hair. He had a long, thin mustache. He wore a light-colored top with a light-colored cape over it. He was wearing vertically striped pants with it.
At some unknown point in time, Moon Isaac Jr. joined the Roger Pirates. After they encountered the Whitebeard pirates 26 years ago and a three-day battle broke out, Kozuki Oden joined the pirates and despite initial skepticism, everyone quickly befriended the samurai. Together, they contested Roger’s final voyage and had many adventures until they finally obtained all the information they needed from the Road-Poneglyphs and headed for the final island. However, when they reached Laugh Tale and found the treasure left by Joy Boy, they all burst out laughing.
After Roger was named “King of the Pirates” as a result, he disbanded the Roger Pirates and the captain was the first to leave the Oro Jackson. They bid him a tearful farewell and then headed for Wano Country, where they dropped off Kozuki Oden and a tearful farewell also ensued.
There is no word on Moon Isaac’s whereabouts after Gol D. Roger’s execution.
- His name was not mentioned until the SBS to Volume 96.
