As far as anyone knows, not a soul has laid eyes on the face concealed behind the terrifying mask, but there is no shortage of whispers and rumors to fill the void. Some say that the visage, forged from a shark's skull, is enchanted, and gives leucas complete control over the small horde of Oceanic White-tips that seem to loyally trail his vessel. Others claim that the mortal man beneath is but a host, and that the mask has a spirit all its own. The few solid clues to leucas' identity are that he speaks with a smooth, cultured tongue; implying an educated upbringing. This is supported by the calculating nature in which he chooses his prey, devising ways to strike them in a away that minimizes casualties to his crew, while maximizing the sheer terror in the targets.
In a fight, the Shark Pirate's preferred method of attack is to blast large groups of targets at close range with a double-shot blunderbuss pistol. While the weapon may not have enough power to kill everyone outright, the scattered shot burning into their skin will nonetheless deter them long enough for leucas slice through the wailing wounded with a pair of sabers. Although he holds the prestigious rank of "Captain", leucas is seldom seen outside of raids, when is terrifying presence and fierce intellect is most critical. Day-to-day runnings of his ship, are left to the Boatswain, as is customary for most pirate crews.
For that reason, his crew are perhaps the most curious as to who among them is really the Captain. A few claim it is the friendly and charming cook, James. However, these same people are almost always immediately shot down for being Treasure Island fanboys.
