What is the full name of the protagonist in Assassin's Creed Unity?

The protagonist of Assassin's Creed Unity is Arno Dorian.

Arno is a French Assassin who becomes involved with the Brotherhood during the French Revolution. The game begins with his childhood and follows his relationship with Élise de la Serre, whose father was a Templar grand master. That personal connection draws Arno into the conflict between Assassins and Templars.

Assassin's Creed Unity is set mainly in Paris, beginning in 1789. Its campaign includes recognizable locations and events from the revolutionary period, including the storming of the Bastille and the Reign of Terror. Arno's movement system emphasizes climbing and descending buildings through Paris's dense architecture.

Élise de la Serre is a major character but is not the playable protagonist. Charles Dorian is Arno's father, while Victor Dorian is not the game's protagonist. Arno's surname also connects him to the wider Assassin's Creed lore through his family.
