Islewan is a massive man whose face greatly resembles that of a walrus, with massive tusks and a large chin. He has black circles around his eyes and a scar under his right eye. Long blonde hair flows on the back of his neck from under his metal helmet, he wears a black and red captain's coat and long gloves almost reaching to his shoulders. He also sports an armor consisting of a barrel-like breastplate and shoulder pads, with porthole-like openings on them.
Islewan cares deeply for the Whitebeard Pirates, as he came to Marineford in order to save Ace. He also had no fear facing Marine Vice Admirals. He has a strong bond with the crew, as he became teary-eyed at the end of the battle following Ace and Whitebeard's deaths.
Abilities and Powers
Islewan was an immediate member of the Whitebeard Pirates early in his pirate career. Four years after Oden joined, the Whitebeard Pirates arrived at an island and noticed a commotion that frightened even the animals. The crew then clashed with the Roger Pirates for three days and three nights before the skirmish ultimately became a gift exchange. Afterwards, the Whitebeard Pirates parted ways with Oden and his family.
Rise to Infamy
Some time prior to the current storyline, Islewan became a known pirate in the New World, and he and his crew became subordinates to the Whitebeard Pirates.
Summit War Saga
Immediately after the Vice Admirals entered the battle, Islewan charged into battle alongside several of the other allied captains. He returned to his ship, and after receiving Whitebeard's command, he and Amadob sailed to the port side of the bay to attack the Marines' battleships.

Anime and Manga Differences
In the manga version of Whitebeard and Ace's funeral in Chapter 590, Islewan cannot be seen among those in attendance. However, the anime version of the exact same scene in Episode 505 explicitly shows Islewan alongside the other attendees. Although it can be assumed that Islewan was at the funeral, there is no visual evidence of his attendance in the manga to support this assumption and, as such, his attendance can only be considered non-canon.
