What is the full name of the Assassin played in the original Assassin’s Creed?

The Assassin played in the original Assassin’s Creed is Altaïr Ibn-La’Ahad.

Altaïr is the central historical character in the 2007 game. He is a Syrian-born Assassin working during the Third Crusade, and the story follows his fall from grace and gradual restoration within the Brotherhood. His name is commonly translated or rendered as “Altaïr, son of no one.”

At the start of the game, Altaïr breaks the Brotherhood’s rules during a mission at Solomon’s Temple. His mentor, Al Mualim, demotes him and assigns a sequence of assassination missions. These targets reveal a wider political scheme involving the Templars and a Piece of Eden.

Altaïr is sometimes confused with Ezio Auditore, the Italian Assassin introduced in Assassin’s Creed II. Altaïr also appears in later franchise material, including Assassin’s Creed: Revelations, which connects his story with Ezio’s.
