In the original Assassin's Creed game, what is the name of the protagonist who belongs to the Assassins?

The protagonist of the original Assassin's Creed game is Altaïr Ibn-La'Ahad.

Altaïr is a Syrian Assassin operating during the Third Crusade in 1191. The game follows his fall from grace after a reckless mission, his demotion within the Brotherhood, and his gradual restoration of rank as he investigates targets across the Holy Land.

The name Altaïr means “the flying one” in Arabic, while Ibn-La'Ahad means “son of no one.” He is voiced by Philip Shahbaz in the first game, with Elias Toufexis providing his voice in later appearances.

Altaïr is sometimes confused with Ezio Auditore, the Italian Assassin who leads Assassin's Creed II and its Renaissance-era sequels. Their stories are connected through the Codex and the Apple of Eden, but they are separate protagonists from different centuries.
