The Italian nobleman who stars in Assassin's Creed's Renaissance trilogy is Ezio Auditore.
Ezio is the protagonist of Assassin's Creed II, Assassin's Creed: Brotherhood, and Assassin's Creed: Revelations. His story begins in late fifteenth-century Florence and later reaches cities such as Venice, Rome, and Constantinople.
He starts as a young Florentine nobleman and becomes an Assassin after his family is destroyed by a political conspiracy. Across the trilogy, he develops from an inexperienced fighter into a mentor and senior figure within the Brotherhood.
Ezio is sometimes associated only with Assassin's Creed II, but his complete character arc spans three games. His popularity also led to appearances in short films, novels, and other franchise media.
