One Piece Wiki

Merlin the Deceitful is a Marine stationed at Jail Island. He appeared in the game One Piece: World Seeker as a minor antagonist and boss.[1]


Merlin is an average-sized man with fair skin, a thin nose, and spiky brown hair he keeps underneath his Marine cap. Unlike normal Marine caps, Merlin's is grey instead of white. He also wears a grey jacket with cuffed sleeves that has a gold zipper and black edging along the sides of the zipper. The jacket also has two breast pockets and three additional pockets on the lower lefthand side. He has a black belt around each of his biceps and another around his chest, and he wears a black "Marine" emboldened harness to carry his shield and bazooka on his back.


Merlin is a cruel, self-serving man, as he defied the Marines by selling weapons to pirates. He also tried used his position as a Marine to pressure Fred to deliver explosives to a pirate ship and threatened him when the young man pushed back against his orders.[1]

When Monkey D. Luffy and Jeanne questioned his position in the Marines, Merlin became quite defensive and retaliatory, ordering his subordinates and the pirates he was trading with to attack them.[1]

Abilities and Powers

Merlin's bazooka and shield.

Merlin has command over his subordinates and those who work for the Marines, like Fred.[1]

Despite being no bigger or better-protected than an average Marine, Merlin possesses a considerable amount of durability compared to them and can take multiple powerful attacks from Luffy before being defeated. However, he can still be defeated relatively easily by Luffy.[1]


Merlin wields a bazooka and a large shield. With his shield, he is able to block some of Luffy's attacks. However, its defenses are no match for Luffy's Gear 3 techniques. He also uses the shield as a weapon, swinging it at opponents.[1]


One Piece: World Seeker

When Fred came to deliver goods for the Marines but questioned why they were working with pirates, Merlin threatened to kill him in an attempt to silence him. Luffy and Jeanne arrived to bring Fred back to his sister, and the two questioned whether or not Merlin was actually a Marine. In retaliation, Merlin ordered his subordinates and the pirates to attack Luffy, who easily defeated them.[1]

Major Battles


  • Luffy and Jeanne suspected Merlin of not being a real Marine. His status as a Marine has not been explored beyond this. His epithet "Merlin the Deceitful" relate to his questionable status.
