Mugren of One Piece

Colonel Mugren (jap. ミュグレン大佐, Myuguren Taisa) was a member of Gol D. Roger’s pirate gang.


Mugren, in Roger’s lifetime, was a very tall and powerfully built man and soon. There was a scar on his forehead and he had some stubble in his beard. He wore a light-colored button-up shirt with a ruffled collar, dark pants, and light-colored boots.


At an unknown time, Mugren joined the Roger pirates. After meeting the Whitebeard pirates 26 years ago and a three-day battle ensued, the pirate gangs held an exchange of goods and subsequently Kozuki Oden joined the Roger pirates. Despite initial skepticism, everyone quickly befriended the samurai. Together they went on Roger’s last voyage and had many adventures. This led them to Skypiea, Water 7, Fish-Man Island, and Zou, among other places. Finally, they had obtained all the information they needed from the Road-Poneglyphs and headed for the last 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.

Nothing is known about Mugren’s whereabouts after Gol D. Roger’s execution.


  • His name and a concept sketch were not revealed until the SBS to Volume 96.
