Ryan Kuhn is known as "The Jackal" in the film Thirteen Ghosts.
The Jackal is the ghost of Ryan Kuhn. In 1887, Ryan was born to a prostitute. By his adult years, Ryan developed a sick insatiable taste for females and began attacking prostitutes. Feeling a desperate need of help, he committed himself to an asylum. After years of imprisonment in a padded room, Ryan went insane, scratching at the walls so violently that his nails were torn off.
The doctors kept him permanently bound in a straitjacket, tying it tighter when he would act out, causing his limbs to contort horribly. Ryan gnawed right through it so the doctors stuck him in a basement cell and locked his head in a cage. There, he grew to hate all mankind. When a fire broke out in the asylum, everyone but Ryan escaped.
is ghost is in his undone straitjacket and his head is still locked in the cage. If he encounters fire, his ghost will disappear.
