Well, there I was so awfully dead in that electric chair. I didn't like it. Would you? It's upsetting. There was still so much killing to do, and there I was, in the void, without a body. But then along came, well, my friend. You know. One of them. Those others over there. The cruel ones... the Master. He thought my work should continue. But in this body. This body in particular, in fact. Let's call it revenge. A certain matter of an exorcism, I think, in which your friend Father Karras expelled certain parties from the body of a child. Certain parties were not pleased, to say the least. The very least. And so, my friend, the Master, he devised this petty scheme as a way of getting back, of creating a stumbling block, a scandal, a horror to the eyes of all men seeking faith, using the body of this saintly priest as an instrument of, well, you know my work. But the main thing is the torment of your friend Father Karras AS HE WATCHES WHILE I RIP AND CUT AND MUTILATE THE INNOCENT, HIS FRIENDS, AND AGAIN, AND AGAIN, ON AND ON! HE'S INSIDE WITH US! HE'LL NEVER GET AWAY! HIS PAIN WON'T END!...Oh...Gracious me. Was i raving? Please forgive me. I'm mad.
~ The Gemini Killer

James Venamun also know as The Gemini Killer is the main antagonist of The Exorcist lll: Legion and the secondary antagonist of The Exorcist franchise. He is Father Karras' archenemy and was a ruthless serial killer in life whose soul was so evil that he became a demon after his death, with the help of Father Merrin's archenemy, Pazuzu.

He is portrayed by Brad Dourif, who portrayed Gríma Wormtongue, Mathias and also voiced Chucky.



The story is almost identical to the film, just with some minor changes, such as the addition of an alternative nickname to Patient X, Tommy Sunlight.


When Father Damien Karras killed himself during the first novel/movie, serial killer James Venamun was executed at the same time, realizing his defeat, Pazuzu transfered Venamun's soul to Karras' dead body. However, Karras' brain and bone tissues were already destroyed, making his body unable to be fully controlled. Karras was eventually found by the locals and sent to a mental hospital, where he stayed locked inside Cell 11 for 15 years under the name of Patient X, until Venamun emerged. One day, Patient X suddenly became hostile and violent towards other individuals, claiming to be The Gemini Killer. After a number of strange occurrences in the hospital, such as patients murdering people, a detective arrived to investigate the case. Upon meeting Patient X, detective Kinderman notices that Patient X has a similiar appearance to Damien Karras, who was his close friend. Later, Venamun tries to kill Kinderman's daughter using one of the patients as a vessel, failing, he attacks Kinderman but was interrupted by Father Paul Morning when he tries to exorcise the patient but the demon Pazuzu intervenes, knocking Morning unconsciousness. After slowly remaining his consciouness, Paul motivates Karras to fight Venamun, which actually works. Karras asks Kinderman to shot him in order to destroy Venamun and Pazuzu's influence, Karras is then shot several times by Kinderman, fatally wounding him and expelling Venamuns' soul in the process. With Karras' soul still inside the body, Kinderman gives him a mercy shot to end his pain and finally sending his soul to the afterlife.
