Il Lupo

"Baltasar and I created Il Lupo. He dresses as his enemy. Wields their intricate weapons. Uses their techniques. Effective, if not perfect, imitations."

- Fiora Cavazza.

Il Lupo (died 1503) was a member of the Templar Order, who had been trained by Baltasar de Silva and Fiora Cavazza to mimic the techniques and skills of the Assassins.

His genetic memories were later used by Abstergo Industries for the training of the Animus recruits, under the title of the Prowler.

Serving the Borgia
After Fiora and Baltasar had tailed and studied the Assassins for some time, they attempted to "create" their own Assassin.

The two trained Il Lupo to master everything they knew about their enemies, such as their movement and assassination techniques. He also wielded his own imitation of their iconic Hidden Blade, a set of "fang-like blades" that were "clumsy but efficient," as Fiora once described.

Upon finishing his training, Il Lupo was sent on missions by Cesare Borgia himself.

Death
"With Baltasar dead, Il Lupo remains the only one who can tie me to any harm done to the Assassins."

- Fiora, just before seeking out Il Lupo.

Some time later, Fiora was betrayed by Cesare, and she joined forces with the Assassins. To hide the evidence of how much she had learned of the Assassin Order while she had worked for the Templars, Fiora planned to eliminate Il Lupo.

She left a signal on the Pasquino statue as a message to Il Lupo that she wished to meet him. Fiora waited for him at the docks at sunset, with an Assassin tailing her for her protection, as she had only recently escaped an attempt on her life by Baltasar. However, Il Lupo quickly killed the Assassin, throwing the body into the river and telling Fiora calmly that she had been followed.

Fiora then began to tell him of an "assignment" from Cesare to eliminate a target on a boat out in the harbor. As Il Lupo looked towards the boat and questioned how he would be able to reach it unseen, Fiora attacked him.

She cut into his back with a poisoned, iron-tipped fan, though Il Lupo retaliated, backhanding her and drawing his rapier. However, his efforts were in vain, and he quickly succumbed to the poison; vomiting, cursing and questioning Fiora as he died.

Trivia

 * "II Lupo" translates to "The Wolf."
 * The grey of his cloak evokes a wolf's coat, and the "fang-like" blades resemble a wolf's fangs, concealed right before the strike.
 * In the Assassin's Creed: Brotherhood Official Strategy Guide (Collector's edition), Il Lupo is shown with an actual hidden blade, instead of his switchblade. Additionally, the blade is worn on his right arm, whereas his switchblade is worn on his left.
