Juli is a fictional character from the Street Fighter series, first appearing in Street Fighter Alpha 3. She is a member of the Dolls, an elite group of female assassins and bodyguards who serve the villainous M. Bison, the leader of the criminal organization Shadaloo. Her name is the German word for the month of July, and she acts as the partner to another Doll named Juni, whose name means June.

Juli is a teenage girl of approximately 16 years of age, with brown hair typically tied up in a bun and brown eyes. Her physical build is similar to that of fellow Doll Cammy, though her figure is noted to be slightly more prominent. She wears the standard Shadaloo Doll uniform: a navy blue leotard with an open back, a small yellow tie, navy blue tights, a matching cap, and black boots. Her nationality is believed to be German, and her real name is Julia. This information connects to a deeper backstory, revealing that she was originally a young woman from the Thunderfoot tribe who was kidnapped by Shadaloo. T. Hawk, a fellow tribesman, recognizes her as his lost love, Julia, and vows to rescue her from the brainwashing that transformed her into Juli.

Juli’s personality has been heavily suppressed by the intense brainwashing and conditioning she endured under Shadaloo. She is typically depicted as cold, unemotional, and completely loyal to M. Bison, often acting and speaking in a robotic, detached manner. Her primary role in the story is as an antagonist and an obstacle for other characters. She is frequently dispatched on missions to eliminate threats to Shadaloo, most notably being assigned to hunt down and kill Cammy, a former Doll who managed to break free from Bison's mind control. In combat, Juli is often paired with her partner Juni, and together they serve as a formidable dual boss battle before the final confrontation with M. Bison in several games.

Key relationships define her narrative arc. Her most significant connection is with Juni, with whom she shares a close bond as a combat unit. Her creator and master is M. Bison, to whom she is slavishly devoted. Beyond these, her primary relationship is with Cammy, her assigned target, and with T. Hawk, who seeks to save her and remind her of her true identity as Julia. Her development across the series is sparse but poignant, focusing on the struggle between her programmed persona and her suppressed original self. In some storylines and endings, Juli begins to show cracks in her conditioning, hinting at a liberation from her brainwashing or falling into a catatonic state, having been reduced to a shell of her former self until she is found by T. Hawk.

Despite being a brainwashed soldier, Juli is a highly capable fighter. Her combat style is nearly identical to that of Cammy, utilizing a fast-paced, acrobatic moveset based on powerful kicks and quick, lethal strikes. She was trained in the martial arts of Shadaloo and has been physically enhanced through the organization's secret experiments, granting her superhuman agility and strength. Her notable special techniques include moves such as the Sniping Arrow, Cannon Spike, and Axle Spin Knuckle. When fighting alongside Juni, they are also capable of performing a unique tag-team move called Psycho Healing, which allows them to recover their vitality together.
