Aladine

Aladdin is a goatsbeard brotula merman and the doctor of the Sun Pirates.

Appearance
Aladdin is a tall, muscular merman. He has dark hair that is in a long ponytail in the back. He has full beard with a goatee. He wears a long vest and carries a trident on his back. He has a tattoo on his left bicep that says "1TC". His Sun Pirates tattoo is on the lower left side of his stomach.

Personality
As a former slave, he is able to understand the kind of trauma that a freed slave goes through. This makes him somewhat sympathetic. He is rather calm and level-headed.

Crew
He seems to get along well with the rest of the crew. He has not been shown having any problems with any members and he did his best to save Fisher Tiger's life.

Koala
Aladdin seemed to be sympathetic towards Koala, having been a former slave himself. It is unknown if he was hateful towards humans like Arlong.

Abilities and Powers
As the doctor of the Fishman Pirates, Aladdin has the medical training to treat his wounded crew members, as demonstrated by diagnosing the heavily injured Fisher Tiger.

As a merman, he is a fast swimmer and stronger than a average human.

Weapons
During his time under the command of Fisher Tiger, he was seen holding a trident, possibly something he kept from his days as a soldier in the Neptune Army.

Past
Aladdin used to be a slave until he was set free by Fisher Tiger. He is first seen in Fisher Tiger's quarters when Hatchan alerted the captain about an enemy ship approaching. He is later seen explaining to Jinbe about how Koala's former life of slavery is affecting her current behavior, making her think she has to work constantly. He is later seen in a town with other members of the Sun Pirates, carrying supplies back to the ship, Aladdin carrying a barrel on his shoulder. That night, he is eating with the rest of the crew and enjoying himself.

When the crew arrived at Full Shout Island, he and other members of the crew wave good bye to Koala. After Tiger was injured, he tried to convince the captain to accept human blood for a transfusion. When Tiger told everyone that he had been a slave, he looks shocked along with the rest of the crew, and listens to Tiger's last words. After that, Aladdin claimed that no matter what Tiger said, he will always be marked as a hero of Fishman Island for freeing all the slaves and for his adventures; these words gave Tiger a sense of happiness before his death.

Trivia

 * His name most likely stems from the Middle Eastern folktale, while his appearance resembles the character Genie from Disney's adaption.
 * His "1TC" tattoo may come from Itachi-uo (イタチウオ), the Japanese name for goatsbeard brotula.
