Alden Roy

This unnamed djinn worked as a sheriff in a small town that catered to tourists.

Powers and Abilities
As a djinn, he was a very powerful monster.
 * Hallucinogenic Touch - The djinns' main ability By touching someone, they can induce a series of delusions on the mind of their target, typically causing them to enter in an unconscious, dream-like state. Inside it, a person can re-live their deepest dreams and desires, over and over again, akin to an endless loop. These delusions can also be induced in a more mild fashion, leaving the person awake, but at the risk of having them break on a mental level due to the mix of reality and illusion. This is eventually fatal to them if they aren't given an antidote. There is also an offshoot race of Djinns, who when inducing the delusions, trap people in a dream world of their greatest fears, and feed off it. When touching their targets, they usually leave a blue mark in the shape of a handprint on the victim. If the victims are strong enough, they can break free of the delusions. Another person can also enter them through dream walking. The offshoot version of djinn's poison cannot be countered by the antidote, or possibly needs a different antidote as they are a slightly different race. The only way for the victim to wake up is to let go of their fears.
 * Pyrokinesis - When they activate their hallucination ability or feeding on their victims they form blue psychic-flames around their hand. This may also be the same energy that illuminates their eyes when using their powers.
 * Telepathy - They can read people's minds and learn their greatest desires or fears.
 * Dream Walking - They can go into their victims' dreams and manipulate them to the point that they can create a Fantasy Universe.
 * Super Strength - Djinns are notably stronger than humans, able to easily over power them.
 * Super Speed - Djinns can move incredibly fast, able to suddenly appear and ambush others.
 * Super Senses - A particular type of Djinn that feeds on fear instead of human blood, can smell human fear and can track their prey by following their scent.
 * Invulnerability - Djinns can only be killed by a silver knife dipped in Lamb blood, or extreme brain damage.
 * Shapeshifting - Djinns can change their form to pass as humans.
 * Immortality - Djinns possess a longer life span than humans and can potentially live forever.
 * Super Agility - Djinns are more agile than humans, while waiting to attack Dean three hid in a tree like birds.
