Speed Jiru

Speed Jiru is somewhat a round man of average height, wearing a brown fez with a white Whitebeard's insignia and a white robe with brown sleeves/leggings, both with Whitebeard's insignia printed on them. He wields a jousting lance for a weapon. He also carries a golden heater shield, also with a purple Whitebeard's insignia.
Speed Jiru is very loyal to the Whitebeard Pirates and Whitebeard, as he was willing to risk his own life in order to save Ace from execution during the war at Marineford.

Atmos

Atmos is a huge man, roughly the size of Jozu, whose choice of clothing he somehow mirrors: he is dressed in sleeveless gray and golden armor, and wears an old-fashioned Asian-themed gray helmet that has bull horns sticking out of it, that makes him resemble a water buffalo, as per his epithet. He has long, mane-like black hair, reaching down to his waist, and his beard is just as long. He has two teeth resembling those of a walrus, but square-shaped and pointing upwards. On each of his arms, he bears a purple tattooed silhouette of Whitebeard's jolly roger.

Haruta

Haruta has a crop of short brown hair, blue eyes, and is fairly short. Haruta wears a green and white 16th century style ruffed outfit with white tights and carries a saber whose handguard resembles the ruffs of Haruta's shirt.
Haruta was loyal to Whitebeard, and wanted to save Ace at Marineford. Haruta cried when Ace died, showing that Haruta cared for him.
As the commander of the 12th division of the Whitebeard Pirates, Haruta has authority over the lower-ranking subordinates. Haruta is presumably very strong: this statement was bolstered when Jinbe remarked that all of the Whitebeard commanders have great strength.

Kingdew

Kingdew is a large tanned man with short blonde hair and hollowed-out cheeks. He wears a pair of long, armored blue gauntlets. He also wears a brown cape that he seems to have pierced to his shoulders, and black and golden yellow striped pants tucked inside simple boots, with a light blue sash around his waist. On the right side of his chest there is a large, elaborate tattoo, which seems to incorporate a dark blueWhitebeard's iconic mustache in it. 

Curiel

Curiel is a tall, muscular, and sturdy man with purple-tinted square-rimmed glasses who wears a watermelon-paterned bucket-hat over his head and a pair of ear protectors that resemble a pair of modern headphones. He also has a purple Whitebeard's jolly roger tattooed on his chin. He wears a sleeveless green coat over a pale reddish-pink shirt, and brown and green spotted army pants tucked inside a standard pair of boots. He has two bazookas strapped to his back.

Blenheim

Blenheim is a huge, muscular man who approaches Whitebeard'ssize. He has a dark ponytailed hairstyle and gray beard. He wears a gray vest and a purple silhouette of Whitebeard's Jolly Roger can be seen tattooed on both of his biceps, right over two pairs of yellow armbands he wears. He has loose grayish pants tucked inside standard boots, and he carried a sword befitting his size at one point.

Twenty-years before the start of the series, Blenheim wore the same kind of outfit but had a black beard.

Namur

Namur appears to be a shark fishman, as evidenced by his shark-like teeth. His teeth stick out of his mouth from his lower jaw similar to Jinbe, but unlike Jinbe he has three small teeth on each side instead of one large. He also has three pairs of gills on his neck.

He is somewhat short and rotund in shape, and his hair is arranged in spikes pointing upwards, similar to Gekko Moriah. He has the number "8" tattooed to the left side of his neck to represent the division that he leads. He also wears a white t-shirt with sky blue sleeves with the star logo for the Criminal brand (colored orange) on his chest. Due to his legs not being visible in the manga, in the anime he was given standard grey pants held up by a belt. Also in the anime, he is also seen with a gray shark fin protruding from his back, and no shoes.
