Born to a prostitue in 1887, Ryan Kuhn grew up to develop a sick and uncontrollable taste for the Female Body. As a result, he became a wild and cunning sexual predator, attacking, raping, and murdering strays and prostitutes in the night.
Seeking treatment, Ryan committed himself to Borinwood Asylum, where he eventually went insane. He scratched at his cell's walls so violently, that his fingernails were torn completely off, making his hands claw-like.
When Ryan attacked a nurse, the doctors put him in a straitjacket and tightened it whenever Ryan acted out, contorting hisLimbs horribly. However, Ryan gnawed through it, so the doctors locked Ryan's head in a cage and locked him in a dark basement cell, where he grew to hate anything human, and would cower and scream madly whenever approached.When a fire broke out at the asylum, while everyone else escaped, Ryan chose to stay behind and meet his deserved fate, and he apparently died in the fire.
Following his death, Ryan's spirit remained bound to earth, and was captured by Cyrus Kriticos to become The Jackal. The Jackal was then moved to the basement of Basileus's Machine with the other eleven ghosts. The Jackal is the fifth ghost to be released.
He eventually comes across Kathy, and viciously attacks her, clawing at her. But he is forced to release her when Kalina arrives and hurls a flare at The Jackal. He pursues Kathy, Kalina and Arthur, but is separated from them by a sliding glass door, the barrier spells preventing him from crossing.
Later, The Jackal re-encounters the group up in the house and attacks Arthur; viciously tearing into his back until Kalina uses another flare to ward The Jackal off. Later, a Latin chant causes the Jackal, along with the other eleven ghosts, to go to the centre of the machine and power it up.
When The Jackal and the other ghosts are freed from the trance, they throw Cyrus into a rotating crest of rings. The house then explodes, destroying its walls and freeing The Jackal and the other eleven ghosts.
- According to Kalina, The Jackal is the sign of Hell's Winter.
- The whispers which signal the Jackal's approach appear to be screaming and/or insane laughter.
- In the original script, the Jackal was called The Hyena.
