Hellequin
- "Caha, along with her brother Cahin, uses theatrics to beguile and brutalize her victims."
- ―Ubisoft

Caha, also known as the Hellequin, is a multiplayer character in Assassin's Creed: Brotherhood. Along with her brother, Cahin, the Harlequin, she works as a Templar Agent for Cesare Borgia and is mentioned to originate from France. Her multiplayer nicnamed is "Harley" this could be due to the Harliquins "Joker" nicname. It should be noted there is no evidence of a romantic relationship between the two despite their fanbase nicnames.
Despite her brightly-colored costume and somewhat eccentric headgear, the Hellequin clearly prefers to act in dramas. Especially the bloody ones. When using her twin golden daggers, she is sure to leave her audience with a grin from ear-to-ear. Her default attire consists of a striped gold and purple jester costume, with an ornate golden mask.
In Assassin's Creed: Project Legacy, Caha and Cahin are first seen doing a performance together, while Fiora Cavazza watches them. The performance turnes out to be a ruse, with Caha, Cahin, and Fiora killing all of the guests attending. Fiora notes that the siblings seem mad, but fun. Later on, after Fiora turns tail and helps the Assassins weaken Cesare Borgia's defense, she joins them in assassinating Caha and Cahin.
Unique Moves
Cunning Trick (Low Profile)
- The Hellequin taps her victim on the shoulder, twirling around them as the victim turns. As the victim searches for the source of the touch, the Hellequin quickly stabs once in the lower back, underneath the rib-cage.
Killer Hop (High Profile)
- The Hellequin vaults over her victim whilst stabbing them in the crevices between the neck and the shoulder blades (the subclavian artery), before landing behind them and nudges the victim with her bottom, letting gravity pull their limp body to the floor.
Curtain Close (Low Profile)
- The Hellequin, once close-range and facing the target, stabs the feet of her victim with her daggers. Once the target can no longer step ahead, she happily takes back one dagger and moves it under the chin, as a bloody finishing blow.

Trivia
- The Hellequin can be unlocked through Uplay for 40 Uplay Points.
- It has been confirmed that the Harlequin is her brother, as stated by their in-game Multiplayer descriptions.
- "Hellequin" is not a play on the word "harlequin", slotting out "harl" for "hell", as people have been led to believe. The Hellequin was the precursor to the traditional harlequin.
