Evie Frye is one of the twin protagonists of Assassin's Creed Syndicate and a Master Assassin of the British Brotherhood during the Victorian era. Born four minutes before her brother Jacob, Evie is disciplined, patient, and deeply committed to the Assassin Creed. While Jacob often charges into danger, Evie carefully studies every situation, preferring stealth, planning, and precision over brute force. Physically, Evie stands around 5'6" to 5'7" (1.68 to 1.70 m). She has fair skin, dark brown hair usually tied back beneath a hood, piercing blue eyes, and a calm, focused expression that rarely betrays her emotions. Her signature outfit is a dark hooded Assassin's coat with crimson accents, leather armor, hidden blades, and a distinctive cane sword that blends elegance with lethality. Evie's personality is defined by intelligence, self-control, and quiet confidence. She values knowledge, history, and the preservation of powerful artifacts, believing that patience and careful planning save more lives than reckless heroics. Though she can appear reserved or stern, she deeply cares for her family, her fellow Assassins, and the innocent people caught under Templar rule. She possesses a dry sense of humor and isn't afraid to tease Jacob, even while cleaning up the chaos he often leaves behind. Evie excels at stealth. She moves silently through the streets and rooftops of London, eliminating targets from the shadows with hidden blades, throwing knives, and her cane sword. Her mastery of infiltration and assassination makes her one of the franchise's most iconic stealth-focused protagonists, embodying the classic ideals of the Assassin Brotherhood.

Jacob Frye is one of the two protagonists of Assassin's Creed Syndicate and the younger twin brother of Evie Frye. Living in Victorian London during the Industrial Revolution, he's the kind of Assassin who charges headfirst into danger with a grin, trusting his instincts more than careful planning. Alongside Evie, he fights to free London from Templar control by building the Rooks, a street gang that stands against the city's criminal underworld and corrupt elite. Physically, Jacob is lean and athletic, standing around 5'7" (170 cm). He has short brown hair, blue eyes, and usually wears a dark hooded Assassin coat trimmed in leather, complete with belts, gauntlets, and a red scarf. His outfit reflects his rough-and-ready style, blending Victorian fashion with practical gear for climbing rooftops and disappearing into the crowds. Jacob's personality is what makes him memorable. He's charismatic, sarcastic, fearless, and often impulsive. He enjoys a good fight and has a habit of acting first and worrying about the consequences later. While his recklessness sometimes creates problems, it also inspires the people around him. Beneath his cocky humor is someone who genuinely wants to help ordinary citizens and protect those who can't defend themselves. Over the course of the story, he matures, learning that true leadership requires patience, responsibility, and working alongside others, especially his more disciplined sister, Evie. Jacob represents freedom, bold action, and rebellion. He isn't the perfect Assassin by traditional standards, but his courage, loyalty, and determination make him one of the franchise's most entertaining and distinctive heroes. Human history keeps inventing complicated political conspiracies, and Jacob's solution is usually, "Have you considered punching the conspiracy?" Somehow, it works more often than it should.
