"To be honest, I'm never entirely sure which I prefer: the study or the outdoors. Both offer opportunity to expand the mind. One offers safety to the body, the other to the soul. I suppose I have been lucky to enjoy both in equal measure."
―William de Saint-Prix.[src]

William de Saint-Prix was an Assassin of the French Brotherhood who was born to an aristocratic family. At the age of 17, he was sent to aid the Colonial Brotherhood in the American Revolution, a mission which cemented his legacy as a particularly venerated Assassin.


Born to a noble French family, William de Saint Prix was blessed with a promising life of opportunities. From his childhood to adulthood, he was educated in the liberal arts and all manners of sciences because they were readily accessible to a child of his standing. As a member of the Parisian Brotherhood of Assassins, he also grew up training in their arts of combat, stealth, assassination, and freerunning.[1]

On his seventeenth birthday, William was sent by the Parisian Brotherhood to the fledgling United States, then fighting for independence against the United Kingdom in the American Revolution, to assist the Colonial Brotherhood in their endeavors. Under the direction of Achilles Davenport and Ratonhnhaké:ton, the Colonial Brotherhood had sided with the Patriots,[2] and accordingly, William did whatever he could to support the revolutionary cause. While he was shunned by the revolutionaries for his aristocratic background, he garnered respect from his Assassin compatriots for his intelligence and courage in his fight against the Templars.[1]


William's contributions to the American Revolution left a lasting impression on the Assassin Brotherhood, and he entered into their histories as an especially heroic figure. So popular is he that even the hacking collective Erudito could not help but express admiration for him.[1]

In 2012 under the title of Huntsman, his genetic memories were first utilized as a tertiary stage Animi Avatar by the Abstergo Entertainment, a subsidiary of the Templar company Abstergo Industries, to influence the general public via the Animus games console.[3] The following year, he and the Night Stalker were the only two characters to be reused in the quaternary stage of the console in spite of their anachronism to this stage's early 18th century setting.[4] Despite his venerated status among Assassins, the Templars did not twist his public profile to slander him, describing him in positive terms and only omitting references to the Assassins and Templars.[1]

Personality and traits[]

Privileged with the best education, William de Saint-Prix was particularly well-versed in science and literature. His expertise was such that he acquired the knowledge to design both his own weapons and original style of martial arts. The former consisted of a makeshift claw held by a handlebar; originally consisting of a single hook, he later developed it further to comprise additional hooks. Keen of mind and courageous at the same time, his qualities and successes as an Assassin factored into the respect he cultivated among his allies in life and his lasting popularity in death.[1]

While he was distrusted by those of lesser lineage, such as the Americans who opposed monarchical institutions, once, while reflecting on the merits between indoors study and outdoors physical fitness, he concluded that he was fortunate enough to have the luxury of enjoying both, a privilege not everyone has.[5]


  • William shares the same surname as Nicolas de Saint-Prix, another French Assassin, though the relation between the two is unknown.
  • Despite his surname being in French and him being of French origin, his personal name is English, "William" being the Anglicized form of Guillaume.
  • An Assassin with similar attire to Saint-Prix is present with Connor in the Assassin's Creed III target render gameplay.
  • Despite his profile crediting him as a significant ally to the American revolutionaries and the Colonial Brotherhood—enough to earn a legacy as a legendary Assassin—he never features in the actual single-player story of Assassin's Creed III. Instead, the protagonist Ratonhnhaké:ton, better known as Connor, achieves all critical objectives against the Templars without William's help.
  • He and Joe are the only multiplayer characters to have been featured in more than one game.
  • Between his appearances in Assassin's Creed III and Assassin's Creed IV: Black Flag, there are some differences; in Assassin's Creed III, he has blue eyes while in Black Flag he has brown eyes. He also appears to have aged and has somehow acquired a scar on his left cheek.
