Which Italian Assassin is the main character of Assassin's Creed II?

Ezio Auditore is the main character of Assassin's Creed II.

Ezio begins the game as a young Florentine nobleman in late fifteenth-century Italy. After a personal tragedy, he becomes involved in the Assassin-Templar conflict and spends years developing from an inexperienced fighter into a leading Assassin.

His story continues in Assassin's Creed Brotherhood and Assassin's Creed Revelations, making him the central figure of the series' Ezio trilogy. The games visit places including Florence, Venice, Rome, and Constantinople, and they connect Ezio's life with Altaïr's earlier legacy.

The full name is commonly given as Ezio Auditore da Firenze, meaning Ezio Auditore of Florence. He is distinct from Arno Dorian of Assassin's Creed Unity and Edward Kenway of Assassin's Creed IV: Black Flag.
