Eldon Frankenstein was a member of Styne Family, a family which has consisted consisted of magic practitioners for several generations.


Eldon Styne was the son of Monroe Styne, and brother to Jacob Styne. Like all members of the Styne family, Eldon had enhancements done to his body such as implanting a second heart and adding extra muscles to his legs, allowing his body to be more durable and allowing for enhanced strength.

Dark Dynasty

After Jacob's death, Eldon started getting 'sloppy'; leaving a body and witness behind when he harvested eyes from a girl. As a result, his father, Monroe was furious with him and tasked him with finding the Book of the Damned. Finding the Winchesters investigating his murder, Eldon followed them and thenattacked Dean with the help of another family member only to have Dean kill the other man and capture him. Held prisoner in the bunker's dungeon, Eldon tells Dean the history of Styne Family and that the Book cannot be destroyed. When Dean is distracted by the information, Eldon rips off his own arm and escapes.

The Prisoner

After learning that his cousin Eli found Charlie Bradbury, Eldon decided to confront her himself. After Charlie refused to give him the Book, Eldon brutally murdered her. Afterwards, he told his father of the stash in the Men-of-Letters Bunker and watched as his little brother Cyrus killed a boy who was picking on him and harvests the boy's arm. Monroe sent Eldon, Cyrus and Roscoe to raid the bunker for the stash and to destroy what they can't take. Eldon prepared to burn Dean's things with the books after making fun of them, but Dean returned but Roscoe is killed by him. Eldon mocks Charlie's death until Dean informs him that he killed Eldon's entire family. Telling Eldon he may have several hearts and other organs but just one brain, Dean shoots him in the head, killing him.

Power and Abilities

Although he could have been considered a magic practitioner, his power and abilities were not shown much. Being capable to be tasked in searching the Book of the Damned, he may be the one of the most powerful magic practitioners in that community.

  • Enhanced Durability - He was able to jump out of a third story building and land without any injury. He was also mostly unaffected by the blood loss of ripping his own arm off.
  • Enhanced Strength - He showed a degree of superhuman strength; he was able to lift a grown man above his head, and rip his own arm off. He also easily kicked in the bunker's door.
  • Enhanced Agility - He had enhanced agility; he was able to casually leap out of a third story building and land gracefully.
  • Supernatural Knowledge - He had a certain degree of supernatural knowledge. He recognized the Mark of Cain and knew the contents of the Book of the Damned.


He had the same weaknesses that the rest of the Styne family had.

  • Massive Brain Damage - As he has only one brain, Eldon was able to be killed by a shot to the head. A single shot to the head instantly killed him.
