- " My cannon arm will rip off your ugly face."
- ―Cannon Arm
Cannon Arm was unique among his fellow crewmen, mostly coming from the fact that he was one of the extremely few who had merged with a weapon over the course of his aquatic transformation. His entire body was covered with seaweed and barnacles, and his left arm had biologically fused with a mini-cannon, thus earning his nickname. Cannon Arm was one of Davy Jones' three elite crewman, besides Quartermaster and Electric Arm.
Cannon Arm often distinguished himself in combat by sometimes putting grenades into his mini-cannon and firing them off without the use of a flint or powder, giving him an advantage over his enemies. Appropriately, he was in charge of the triple guns and was known to love his work. He fell into the maelstrom.
