Background / History
Ye Mu is a transmigrator who arrives on Sky Island with knowledge of the One Piece world but little understanding of his own situation there. He befriends the young Enel and returns the Rumble-Rumble Fruit rather than taking the power Enel had found. Enel then leads him toward another fruit, which Ye Mu eats after being swallowed by the Lord of the Sky Island 2 3 4 6 7.
The two train together on Sky Island. After defeating the Lord of the Sky and taking over Shandora, Ye Mu shifts their emphasis toward physical conditioning, using a sea-cloud gravity room built by Pagaya. Years later, he sets out as captain of the Sky Pirates aboard the Twin Goddesses 9 17 54.
Ye Mu initially lacks memories that explain his identity. Lililu later reveals that Rocks D. Xebec created his body using Charlotte Linlin’s Lineage Factor and Rocks’s heart, intending to create a new life into which Rocks could transfer his consciousness. Further tests find five sets of Lineage Factors in Ye Mu’s body. The revelations do not establish that Rocks is his biological father 132 192 208 278.
Appearance
After ten years on Sky Island, Ye Mu is described as a handsome young man nearly two and a half meters tall, with a defined physique and a gentle bearing 17.
- Hair and eyes: Vivid fiery-red hair and bright eyes 17.
- Early pirate attire: Loose lantern pants, bare feet, and a shortened windbreaker; he favors red and black 17.
- Flame Emperor Form: His hair burns upward, flame clouds coil around him, and golden and red energy trails behind him. In a later manifestation, three differently colored firebirds appear behind him 294 574.
Personality
Ye Mu pursues strength to explore and live freely, rather than to rule for its own sake. He adapts his training when trying to perfect every skill proves impractical, and he refuses Shiki’s offer of help against Sengoku because he wants to test the world’s limits himself 71 266 293.
He treats his crew’s dreams as his responsibility, but does not want companions forced into joining. His care can be practical—he assigns instructors and work suited to crew members—while his conduct toward enemies can be ruthless, as when he kills Musshuru or threatens captives to control a standoff 24 41 53 80 138.
Abilities & Skills
Devil Fruit powers
- Flame-Flame Fruit: Ye Mu can turn into and produce flame. After awakening, his power extends beyond his body to the surrounding environment 7 289 292 308.
- Hot-Hot Fruit: Its awakened power lets him alter and absorb heat from surrounding matter, strengthening his attacks while weakening opposing ones. His “Zero-Degree Freeze” drains heat so rapidly that it freezes Sengoku’s shockwave 290 308.
- Soul bestowal: An ability arising from experimentation on his Lineage Factor lets him split off portions of his own soul and life force and give them to objects. It cannot take other people’s souls or life force. He uses it to give his Flame-Flame and Hot-Hot powers independent, intelligent forms called Ye Mu No. 1 and Ye Mu No. 2 293 294.
- Float-Float Fruit: Ye Mu gains Shiki’s former power and uses it to move a celestial body above Mary Geoise and relocate Alchemy Island 319 348 384.
Haki and physical combat
- Ye Mu uses Conqueror’s, Armament, and Observation Haki. His Conqueror’s Haki can overwhelm lesser opponents, while his Armament techniques eventually include Internal Destruction 16 264 304.
- His strength and resilience let him withstand Garlan Annu’s attacks and continue fighting after severe blows from Bullet and Sengoku 68 130 288 290.
- He is a capable swordsman, though he acknowledges that he is not a pure swordsman. Battles with John and Shiki expose gaps in his technique and accelerate his improvement 80 230 304.
