Lt. Colonel Jack Sullivan, portrayed by Sherman Augustus[1], is a recurring antagonist in the fourth season of Stranger Things. He believes he can stop the evil in Hawkins once and for all.





While investigating the events surrounding Chrissy's death, he raids the home of Dr. Sam Owens, demanding information regarding Eleven. He believes that Eleven is the cause of the destruction and wants to neutralize her. After his attempts became futile, he ordered an attack on the Byers' residence. Two agents affiliated with Hawkins Laboratory were tasked to protect the family, with one dying in the line of duty and the other being captured and tortured on Sullivan's orders.


He believes strongly in his beliefs, going to extreme lengths to find answers. Sullivan is very corrupt, hypocritical, and paranoid where he arrogantly believed Eleven to be responsible for the murder spree in Hawkins, despite her to being claimed "dead" when she was really living peacefully on the other side of the United States. Sullivan was willing to attack American citizens, including children to achieve his targets. He even inflicts torture on his fellow Americans, despite criticizing the use of torture earlier.

He is shown to have a slightly understanding side during Agent Wallace's interrogation; he considers not harming Eleven for his desired goal. However, when reaching the Nina Project facility, Sullivan ordered his men to harm Eleven and refused to listen to reason when Owens tried to explain Eleven wasn't the culprit behind the murders.
