The surname of Jacob Frye, the main protagonist of Assassin's Creed Syndicate, is Frye.
Jacob Frye is a British Assassin who operates in London during the Industrial Revolution. Alongside his twin sister Evie, he works to remove Templar influence from the city and establish an Assassin presence there. The twins are the game's two playable protagonists, with Jacob generally associated with direct combat and gang leadership.
Syndicate was released in 2015 and depicts London in 1868. Jacob and Evie become involved with the Rooks, a street gang they build into a force opposing the rival Blighters. Their enemies include Crawford Starrick, the Templar Grand Master controlling much of London's criminal and industrial power.
The surname can be confused with names from other games in the series, especially Kenway and Auditore. Jacob and Evie are siblings, not characters from the Kenway family, and the Frye twins are original fictional figures created for the Victorian London setting.
