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) is an exclusive multiplayer character featured in Assassin's Creed: Brotherhood, available via pre-order on Gamestop.com. The character is also available by buying the Limited Codex Edition (currently available in Europe and Australia). It was stated by Ubisoft that he might also make an appearance in the single-player mode, along with the other multiplayer characters. He uses two thin, needle-like daggers.
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 them.

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.
More is Merrier:
The Harlequin pushes his target down and stabs their chest maniacally several times. (as shown in the video below at 0:55)
