Background / History

Merlin was born to Lance and Lucia. After their deaths, Yol cared for him because Lucia had once cared for her; Merlin became notably mature and withdrawn while still young. He retains memories and values from a past life, which often conflict with the survival-of-the-fittest outlook taught by his father. 2 20 37

During the destruction of Frevanz, Merlin discovered that his reincarnation-linked Equipment Slot had become a talent. Surrounded by soldiers exterminating infected people, he armed himself with his family’s century-old heirloom dagger and resolved to survive. 1 2

His first encounter with Devil Fruit power came through Viscount Mela. Merlin stripped Mela’s Jungle Wolf Origin Power, discovered that Devil Fruit origins could create additional equipment slots, and killed Mela after removing his power. 6

Merlin escaped Frevanz with Yol and Lami. In the Fultons Mountain Range, the three chose to remain together rather than part with one another. Merlin subsequently trained in the wilderness, developed his body-tempering and contemplation methods, and learned to manage the mental influence exerted by creature equipment. 20 23 26 29

He later pursued the nobles connected to the Frevanz incident, afflicting them with plumbism through Black Flame and stealing their wealth to fund his future organization. 70 84 85

As his influence expanded, Merlin formed a pirate crew, built an intelligence network with Fulvio, and turned Germa 66 into an allied power under his control. 84 118 120

By the time he established himself on Beehive Island, Merlin had drawn former Marines, revolutionary forces, giants, Germa, and other allies to his side. He rebuilt the island into the Tower of Babel Beehive and later advanced through starry-sky cultivation. 200 207 212

Appearance

Merlin is a handsome young man with black hair, black eyes, sharp brows, a high nose bridge, thin lips, and an intense gaze. He is commonly seen carrying a black longsword at his waist and a dagger on his right thigh. 31 70

• Black hair and dark eyes. 70
• Often wears a black longsword and thigh-mounted dagger. 70
• Can assume numerous forms through his equipment and synthesized abilities, including jungle wolf, Oni, vampire, mercury vapor, giant, and Demon Form. 6 69 116 140
• His Vampire Form includes pointed ears, black bat wings, ruby-like eyes, and Black Flame. 140

Personality

Merlin is pragmatic, highly adaptive, and willing to kill when he considers it necessary for survival or to remove a threat. The violence of Frevanz hardens him, though he remains conscious of the tension between his old moral values and the ruthless world around him. 6 20 62

He is deeply protective of those he considers his own. Merlin explicitly values the lives of people in his circle, protects allies from consequences when possible, and repeatedly offers vulnerable people a path to safety or strength. 72 120 152 159 212

Merlin is also analytical about power. He experiments with equipment, refuses to bind or synthesize items hastily, studies adverse mental effects, and treats every new ability as something to understand rather than merely possess. 2 7 23 51 128
