Arno Victor Dorian is a fictional character in Ubisoft's Assassin's Creed video game franchise. He serves as the protagonist of the 2014 game Assassin's Creed Unity, in which he is portrayed by Canadian actor Dan Jeannotte through performance capture, and voiced by Godefroy Reding as a young child. The character's other appearances include the novelization of Unity, also released in 2014; the 2017 mobile title Assassin's Creed Unity: Arno's Chronicles as its titular player character; as well as cameo appearances in the 2014 game Assassin's Creed Rogue and the 2016 live-action film adaptation of the series.
Within the series' alternate historical setting, Arno was born into a French-Austrian noble family who have long been loyal to the Assassin Brotherhood, a fictional organization inspired by the real-life Order of Assassins. Arno is orphaned as a child after his father is murdered, leading to his adoption as a ward by the de la Serre family, who are secretly members of the Templar Order, the mortal enemies of the Assassins, in turn inspired by the Knights Templar military order. The romantic relationship between Arno and his childhood friend Élise de la Serre is central to the story of Unity, the events of which are set in motion when Élise's father is killed. Arno resolves to investigate the reason behind the murder and join the Assassins at the onset of the French Revolution.
The character has received a mixed critical reception, with some reviewers criticizing Arno as dull and not being particularly memorable as a series protagonist, while others praised him as a likeable character with an interesting backstory.
