Harlequin
- "Behind the gaudy costume and twisted smile lies the soul of a merciless assassin. You call yourself the Harlequin. Your victims will call you a walking nightmare."
- ―GameStop

The Harlequin (real name: Cahin [1] ) is an exclusive multiplayer character featured in Assassin's Creed: Brotherhood, available via pre-order on Gamestop.com, Play.com and Ubisoft.com. He is also available in the HMV Exclusive Edition and the Limited Codex Edition of Assassin's Creed: Brotherhood. A jack-in-the box of the Harlequin is also available to those who pre-order the Collector's edition of Assassin's Creed: Brotherhood from GameStop.
He uses two stiletto daggers as his primary weapons. Another playable multiplayer character, known as the Hellequin, is confirmed to be his sister, as stated by their multiplayer character descriptions.
In Assassin's Creed: Project Legacy, Cahin and his sister Caha are first encountered by Fiora Cavazza as they perform together. The performance turns out to be a trap, however, with Cahin, Caha, and Fiora killing all the guests present. Fiora notes to herself that the siblings seem to be mad, yet fun. Later on, when Fiora changes sides and joins the Assassins in weakening Cesare Borgia's defenses, she aids in assassinating Cahin and Caha. The attack was successful, with the siblings dying together during the assault.

Unique moves
The Killing Joke
The Harlequin stabs the back of the victims neck, flips over their back, then stabs the victim in the heart and to the right of the chest cavity, leaving them incapacitated and internally bleeding to death (as shown in the video below at 0:38).
Sacrifical Strike
From behind, the Harlequin impales his twin blades into his target's neck, causing them to go limp. The body then falls to the ground as he withdraws the daggers.
Killing Wheel
The Harlequin does a cartwheel, kicking his victim in the head and knocking them to the floor. He then quickly stabs his victim in the chest, and allows them to fall to the floor as he withdraws his weapons (as seen at 0:19 in the video below).
More is Merrier
The Harlequin pushes his target down and stabs their chest maniacally several times. This can be performed running at or jumping on a target (as shown in the video below at 0:55).
