Known as the "Bohemian Knight," Doma is a notorious pirate captain from the New World who threw in his lot with Whitebeard. A dual-wielding swordsman accompanied by a pistol-firing monkey, he joined the assault on Marineford in the bid to rescue Ace.
Curly black hair and a beard whose lines reach up toward his eyes mark Doma's face, and a sizeable red headband sits across his brow. Around his neck hangs a chain set with large pale-blue square gems, while a scar shows on the lower right of his throat. Closed at the front by a belt, his garment is a long coat in light brown trimmed at the collar, which is broad and dark red, and at the cuffs. Beneath it he wears slack blue trousers pushed down into plain boots.
A monkey rides on his shoulder, typically coiling its prehensile tail about his arm. The animal also handles a flintlock pistol, discharging it for Doma once fighting begins.
Doma's devotion to Whitebeard stands out above all else. Rather than escape along the route his captain had opened with the Gura Gura no Mi, he chose to gamble his life on freeing Ace, and he cheered loudly when Whitebeard urged his allies onward. The fall of Whitebeard left him weeping in grief. The anime additionally portrays a man who can honor a worthy foe, telling Momonga that crossing blades with him was an honor.
At an earlier point Doma and his crew were beaten by Portgas D. Ace and laid down their arms to him, a surrender that helped earn Ace his rank as Second Division Commander. Doma later brought his crew among the forty-two pirate groups serving Whitebeard that struck at Marineford to halt Ace's execution. He fought the Marines beside Whitebeard and, on his captain's command, helped shield Luffy and Ivankov as they pushed toward the scaffold. The anime adds a clash in which he blocks Vice Admiral Momonga from reaching Luffy. After Whitebeard died and Shanks arrived to call a halt, Doma withdrew from the field unharmed. As a swordsman he favors a reverse-grip two-blade method, nimble footwork, and kicking strikes.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
