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, a scar running diagonally across his face, and seen smoking a cigar. He has Whitebeard's symbol tattooed on his right biceps, along with three little circles, and he wears a sleeveless jacket.

Abilities and Powers
As the commander of the 15th division, Fossa has authority over the lower-ranking subordinates. Fossa seems to be a swordsman, although his exact level of swordsmanship skills is unknown. He was somehow able to engulf his sword in flames. Whether this stems from a Devil Fruit or not is currently unknown. Also, like the rest of the Division commanders, he is probably very strong, since Jinbei has mentioned that the Division commanders have the "strength of 100 men".

Trivia
