The Decalvan Brothers are two infamous New World pirates who allied themselves with the Whitebeard Pirates.


The Decalvan Brothers appear to be twins (since they share the same birthday), and both wear overalls. Both have wide faces (though one of them is wider than the other) and flowing black hair. The one with the wider face has sharper teeth. Each brother opens one of their eyes which is large and black around the rim, and closes the other which has a scar over it; which eye they open and close are opposite to one another.

They both wear a brown and yellow pirate tricorn hat with polka dots bandanna underneath it (one red, and one blue). The hat bears their Jolly Roger: two skulls and a cross-bone, with a wavy design over it. They both wear yellow long gloves with razor-sharp nails at the end on both hands.


Not much is known about the Decalvan Brother's personality, other than that they were willing to fight in order to rescue Ace from execution.

Abilities and PowersEdit

The Decalvan Brothers have managed to make themselves an infamous reputation in the New World, and have managed to ally themselves with the Whitebeard Pirates. After Squard, they were Whitebeard's choice in leading the allies to attack Marineford.

They wear gloves with razor-sharp nails at the end, which are most likely used in battle, similar to Sham and Buchi, the Nyaban Brothers of the Black Cat Pirates, albeit much stronger. In the anime, they were able to fight on par with Vice Admiral Dalmatian to stall him.


Marineford ArcEdit

The Decalvan Brothers and their crew are first seen, along with a fleet of 42 other infamous pirate crews, allied with the Whitebeard Pirates, attacking Marineford to save Portgas D. Ace from his execution.[2] After failing to reach Squard, Whitebeard contacted the Decalvan Brothers and gave them, along with certain other captains, the command of all the New World pirates in retaliation to Ace's early execution time.[3]

After Whitebeard was stabbed by Squard, they were seen commenting on how ashamed he must be feeling.[4] They were later seen among the group of New World captains who were backing up Luffy and Ivankov on Whitebeard's orders. In the anime, the brothers dueled Vice Admiral Dalmatian to a stalemate.

When the Blackbeard Pirates launched a barrage of bullets and blades at Whitebeard, killing him in the process, the Decalvan Brothers were seen crying. Upon the arrival of Shanks and Sengoku calling the war coming to a close, they and the rest of Whitebeards crew left.

Post-War ArcEdit

They, along with the rest of the crew attended the funeral of Whitebeard and Ace on a undisclosed location somewhere on the Grand Line.[5]

Manga and Anime DifferencesEdit

In the anime, an additional scene was shown that the Decalvan Brothers fought against Thatch and were beginning to overpower him when Ace joined the fight. The outcome is unknown but it is very likely that the brothers were overpowered by the two commanders because after the battle it was stated that the bounty of Portgas D. Ace was risen again.

In the manga they were always standing together, with one brother partly covering the other one, resembling conjoined twins. In the anime they were always standing further away from each other.

In the anime they were given an additional scene of fighting against Vice Admiral Dalmatian when Whitebeard ordered the allies to backup Luffy; this was not shown in the manga.
