Fossa

Fossa is the commander of the 15th division of the Whitebeard Pirates.

Appearance
Fossa is a large and muscular older looking man, with a bald patch on the top of his head, a mustache, and a scar running diagonally across his face. He has Whitebeard's symbol tattooed in crimson on his right bicep, along with three little circles, and he wears an open dark blue sleeveless jacket, with lighter edges, and loose light brown pants tucked inside his boots and are held up by a reddish brown belt. He carries his weapon of choice, a katana with a square tsuba, on his left hip attached to his belt, but was also seen carrying it over his left shoulder with a long strap. He is seen smoking a cigar in all of his appearances.

Abilities and Powers
As the commander of the 15th division, Fossa has authority over the lower-ranking subordinates. He is very strong, like the other division commanders.

Weapons
Fossa seems to be a swordsman, although his exact level of ability remains unknown; however it is presumably quite high. He wields a katana with a square shaped hilt, and was somehow able to engulf the blade in flames. Whether this ability stems from a Devil Fruit, a Dial, friction or another method is currently unknown. In the anime, however, he was shown doing so with his cigar, which may suggest that the sword is coated with some kind of flammable liquid.

Marineford Arc
Fossa first appeared when Whitebeard arrived at Marineford in order to save Ace. He landed on the ice created by Aokiji along with the other Commanders, and started to attack, slashing enemies with his flame-covered sword. He was seen again when Admiral Kizaru kicked Luffy: he assaulted the high-ranking Marine with other Commanders, giving Luffy a chance to carry on. Later, he was shocked at witnessing Squardo stabbing Whitebeard in the chest, and when his captain's quake-attack failed to destroy the siege wall, he commented on the unusual type of iron that was used in making the wall. He entered the plaza behind the wall with the others and was seen fighting alongside his comrades. He later joined Jinbei and other Commanders in protecting Whitebeard's back, and he was the one to reveal that both his captain and Red-hair possessed Haōshoku Haki. He appeared shocked when Whitebeard declared his will to sacrifice himself in order to save his "sons," and incredulously witnessed Admiral Akainu piercing Ace with his magma-fist. When the latter died, he appeared angry, declaring that it couldn't be really happening. When the Blackbeard Pirates killed Whitebeard, he was seen crying, his cigar falling from his mouth for the first time. When Akainu resurfaced from the ground, he commented on his ability to melt the rock, and was among the others when they faced off against the Admiral in order to save Luffy. He was seen mourning the results of the war along with the other Whitebeard Pirates. Upon the arrival of Shanks and Sengoku calling the war to a close, he and the rest of Whitebeard's crew left.

Post-War Arc
He, along with the rest of the crew attended the funeral of Whitebeard and Ace at an undisclosed location somewhere in the Grand Line.
