In season three, she is planning to sell her house and move out of Hawkins, much to Hopper’s dismay who tries to convince her to go on a date with him. Even though she does have feelings for him, Joyce tries to avoid getting into another relationship. She is mainly more interested in figuring out why the magnets in her house keep falling off her fridge and while investigating the reason behind this, she and Hopper uncover a Russian conspiracy. After infiltrating a Russian lab beneath the new Starcourt Mall, where the Russians have opened another portal into the Upside Down, Joyce is forced to close the portal by turning off the Russian machine used to open it with Hopper in the room, and Hopper ends up being presumably dead. Joyce becomes a mother figure to Eleven after taking her in when Hopper supposedly died. The Byers family and Eleven move to California three months after Hopper's supposed death.

Joyce has a stay-at-home job and receives a package from Russia carrying a doll, which has a note inside that reveals Hopper is alive. She and Murray call the number on the note and contact "Enzo", a prison guard that Hopper has bribed, who demands $40,000 in exchange for Hopper's freedom. Joyce obtains the money and flies to Alaska with Murray Bauman, where they meet Yuri Ismaylov, a Russian smuggler and pilot that smuggles American goods into the Russian prison camp. Realizing the profit that can be made, Yuri Ismaylov drugs Joyce and Murray and flies them to Russia. En route, Joyce and Murray knock out Yuri and crash in the wilderness.

He grows irritated with the party and has a rocky relationship with Max at first. Will reveals his apparent flashbacks to the Upside Down to Mike and he accompanies Joyce, Bob and Will to the lab when Will's health deteriorates. When Eleven reappears, he is grateful that they do not have to fight the battle without her but angry at Hopper for keeping her hidden for the past year. Mike is key on getting Will’s memory back to tell the group to close the gate. Before Eleven leaves to close the gate, Mike tells her he cannot lose her again and she promises him that he will not. A month after Eleven closes the gate, the two attend the Snow Ball together and share yet another kiss.

The next summer, the two are dating, but Hopper manages to separate them because they are spending too much time together. When Eleven and Max realize Mike has been lying about his grandmother being sick she eventually breaks up with Mike. However, the two reconcile at the hospital waiting for Nancy. While Eleven tries to find Billy, Mike expresses concern that everyone is careless with Eleven‘s powers and confesses that he loves Eleven.

On the day that Eleven and the Byers family move away, Mike promises Eleven that he will keep in contact and schedules visits at Thanksgiving and Christmas.

In the spring of 1986, Mike and Dustin join the Hellfire Club, Hawkins High School's Dungeons and Dragons club, led by Eddie Munson. Though Lucas is also a member, he has committed himself to the Hawkins HS basketball team, putting him at odds with Mike and Dustin, who urge him to side with them—the "nerds and freaks." He and Eleven maintain a long-distance relationship with letters, and for spring break, Mike flies to California to visit Eleven and Will at their new home in Lenora Hills. Though Eleven insisted to Mike that she had friends and was living a semi-popular lifestyle, Mike discovers that she was lying to hide the heavy bullying she experiences from other students. He witnesses Angela and a gang of girls humiliate Eleven at Rink-o-Mania, and he is shocked when Eleven retaliates with physical violence. The following day, Mike and Eleven argue when she expresses her dissatisfaction in the relationship, pointing out Mike's strange reluctance to say he loves her. When Eleven is arrested for attacking Angela, Mike, Will, and Jonathan are distressed and unsure how to help her—until Sam Owens sends agents to inform them that Eleven has accepted his offer to begin training to get her powers back. At the Byers home, the three are being guarded by two agents, until U.S. Army soldiers attack the house, forcing them to escape with the help of Jonathan's friend Argyle, bringing a wounded Agent Harmon with them. After Harmon dies and leaves them with a phone number to reach Owens and Eleven, Mike enlists the help of Dustin's girlfriend Suzie, who lives in Salt Lake City, Utah. There, Suzie provides them coordinates for the Nina Project, which is in Nevada. Along the way, Mike expresses his inner anxieties regarding his relationship with Eleven, scared that she will eventually realize that she doesn't need him as he needs her. As the U.S. Army closes in on Eleven, Mike and the California Crew arrive, giving Eleven a chance to destroy her attackers and their transportation. Together, they venture to a Surfer Boy Pizza location in Nevada to build Eleven a sensory deprivation tank for her to travel into Max's mind to protect her from Vecna. When Vecna overpowers Eleven, Mike professes his love for her, giving her the strength to overpower him.

Eleven

* Portrayed by Millie Bobby Brown
* Appears in: ''Season 1'', ''Season 2'', ''Season 3'', ''Season 4''
* Status: Alive

Eleven is a telekinetic girl who is the sole match for the creatures of the Upside Down. She later becomes Jim Hopper's adoptive daughter and Mike Wheeler's girlfriend.

Born to Terry Ives, Eleven was abducted by Dr. Martin Brenner at birth and taken to Hawkins National Laboratories to hone her telekinetic abilities alongside other gifted children. In 1979, she is bullied by the older numbers for exhibiting a poor usage of her powers, but she finds kindness in a lab orderly, who encourages and supports her. Eventually, Eleven demonstrates great power, but she is targeted by the older children once again and threatened with death. The lab orderly urges Eleven to escape Hawkins Lab, but she frees the orderly, who reveals himself to be Henry Creel / Subject 001 (One). One proceeds to kill everyone in Hawkins Lab, with the exceptions of Brenner and Eleven. When One attempts to convince Eleven to join him in a mission for human dominance, Eleven rejects him, and the two fight. The adult One overpowers the eight-year-old Eleven, but Eleven's powerful, loving memory of her mother gives her the strength to overpower One, sending him into the Upside Down, where he becomes Vecna. Eleven falls into a coma, and her abilities, memory, and intellect are reset when she awakens.

After her escape at the beginning of season one, Eleven is befriended by Mike, Dustin, and Lucas, who believe she can help them in finding Will. In the kids' ''Dungeons and Dragons'' party, she is the Mage. She spends the majority of the first season hiding and running from the "bad men", meaning the lab workers. She helps the boys locate Will, and she fends off threats for them along the way. In the season one finale, she presumably dies after fighting the Demogorgon, though she actually survived and was sent to the Upside Down alongside the Demogorgon.

In season two, following the events of the season one finale, Eleven is shown to escape the Upside Down through a gate in a hallway in Hawkins Middle School. Hopper then becomes a father figure to Eleven, though he hides her from Mike, Dustin and Lucas for her safety. Eleven grows increasingly frustrated at this isolation from the other world, and she temporarily flees Hawkins in search of her biological mother, Terry Ives. She later ventures to Chicago, Illinois, where she meets a girl named Kali (subject 008 / Eight) and her group of vengeful killers. Despite going through a journey of self-discovery, Eleven ultimately returns to Hawkins, reuniting with Mike and her friends. She closes the gate she opened the year prior in Hawkins Lab, ending the Mind Flayer's connection to Hawkins. Hopper legally adopts her as his daughter.

In season three, Eleven is actively dating Mike, much to Hopper's chagrin. When Hopper attempts to separate Mike and Eleven, he forces Mike to lie to her. She suspects this ruse, and she consults Max Mayfield, who helps her discover her individuality. When the Mind Flayer's threat emerges once again, Eleven is pursued once more. After being bitten by the Mind Flayer, Eleven loses her powers, as well as Hopper at the end of the season and moves with the Byers family to Lenora Hills, California.

In spring 1986, Eleven has attended Lenora Hills High School alongside Will, and here she experiences incessant, daily bullying by fellow classmate Angela and her friends. When Mike visits El and Will, Angela and her friends gang up on Eleven at Rink-o-Mania, and Eleven strikes Angela in the face with a roller skate in retaliation. She is taken into police custody, but Dr. Sam Owens intercepts her arrest, offering her a chance to restore her abilities. After she accepts, Owens takes her to a facility in Nevada, where she reunites with Brenner. She is forced to confront her traumatic memories in Hawkins Lab taking her to a facility where she relives her repressed memories of her time at Hawkins Lab. After recalling the lab massacre, Eleven finds that her abilities are restored, and once she learns of the Hawkins Gang's plan to kill Henry / One / Vecna, she attempts to travel back to Hawkins with Owens, though Brenner intervenes and insists on keeping Eleven. After the U.S. Army attacks the silo lab, Brenner attempts to flee with a sedated Eleven, only to be shot. Eleven manages to save herself, and she refuses to forgive a dying Brenner. She later telepathically saves Max from Vecna and revives her when she succumbs to her injuries.

Dustin Henderson is a friend of Mike, Will, and Lucas, and a goofy and quick-witted boy whose cleidocranial dysplasia causes him to lisp. In the ''Dungeons and Dragons'' party, Dustin is the Bard and has arguably the most extensive knowledge of the game, particularly the monsters. He has a crush on Nancy, and while both he and Lucas have feelings for Max in season two, Lucas and Max ultimately end up together. He also befriends Steve, who gives him advice on how to make girls like him.

Prior to season three, Dustin spends a month at a science camp and, thanks to Steve's advice, is able to get a girlfriend, Suzie, whom he claims is a genius and is "hotter than Phoebe Cates." His friends are skeptical as to whether or not she actually exists as he is unable to get in contact with her over his makeshift radio tower, "Cerebro." Dustin instead discovers the coded Russian transmission and, along with Steve, Robin, and Erica, ventures into the Russian's underground lair. He later proves Suzie's existence when he contacts her for Planck's constant in the season finale (She forces him to sing "Never Ending Story")

Now in high school, Dustin, Mike, and Lucas join a Dungeons & Dragons club named "The Hellfire Club," led by the eccentric Eddie Munson. After Chrissy Cunningham is killed by an unknown entity, Dustin dubs the entity as "Vecna." During a plan to kill Vecna, Dustin and Eddie successfully distract the demo-bats away from Steve, Nancy, and Robin, but become trapped in Eddie’s trailer. Protecting Dustin, Eddie exits the trailer and lures the bats away from the trailer. While fighting them, Eddie is knocked down and his flesh is rendered, leaving him mortally wounded.

A fight ensues with Jason briefly overpowering Lucas, however after he sees Max beginning to levitate he summons the strength to continue which results in him knocking out Jason.

Lucas observes in horror as Max begins to succumb to Vecna's Curse, her bones are crushed and she loses her sight. This leaves Lucas devastated as he cries hysterically as Max dies in his arms, before Eleven psychically resurrects Max, barely saving her.

* Portrayed by Cara Buono
* Appears in: ''Season 1'', ''Season 2'', ''Season 3'', ''Season 4''
* Status: Alive

Karen Wheeler is the mother of Nancy, Mike and Holly and wife of Ted. Although a loving mother at heart, she remains largely clueless about her children's activities up until the destruction of Hawkins by Vecna, and often tries to directly connect with them rather than trying to understand them. Nancy believes she only married her husband to fit the image of a nuclear family.

At the end of the second season and the beginning of the third, she develops a sexual attraction towards Billy Hargrove, partly out of boredom with her husband, but ultimately decides against acting on these feelings to avoid splitting her family apart; her brief submission to them, however, indirectly results in Billy being possessed by the Mind Flayer. Later, she finally connects with Nancy by encouraging her to continue pursuing the story she was fired for working on against her editor's orders.

Martin Brenner

* Portrayed by Matthew Modine
* Appears in: ''Season 1'', ''Season 2'', ''Season 4''
* Status: Deceased
* Died in: ''Season 4''

Dr. Martin Brenner, who is referred to as "Papa" by Eleven and the other children he experimented on, is the head scientist of Hawkins Laboratory and the experiments performed there. He is a callous and manipulative scientist, having abducted Eleven from her mother, Terry Ives, whom he later subjected to electroshock therapy to destroy her mind and thoughts. Brenner then put Eleven through numerous experiments, one of which saw her use her abilities to accidentally establish a link to the Upside Down. After Eleven escapes the lab, Brenner and his team hunt for her throughout Hawkins while covering up the actions of the Demogorgon they unknowingly let loose. Brenner is apparently killed by the Demogorgon in the first-season finale, though a former worker named Ray claimed Brenner was still alive during his attempt to plea for his life to Eleven and Kali.

In season four, Brenner is revealed to still be alive and working with Dr. Owens on a project called "NINA", which they hope can restore Eleven's powers. NINA is a specialized sensory deprivation tank and experimental drugs that allow Eleven to vividly recall memories of her time in the lab. Flashbacks to 1979 show that Brenner was experimenting on at least thirteen children alongside Eleven until all of them except for her were murdered by subject 001 (Henry Creel/Vecna), whom Eleven overpowered and banished to the Upside Down. The exertion put Eleven in a coma that erased most of her memories and weakened her powers, which Brenner began attempting to restore. Brenner's experiments on Eleven throughout the first season are revealed to have been attempts to locate Henry, whose powers he sought to replicate in the other children.

The NINA project ultimately succeeds in restoring Eleven's powers, but U.S. Army troops led by Lt. Col. Jack Sullivan storm the facility and kill the staff, believing Eleven to be responsible for a string of murders in Hawkins (which were in fact committed by Vecna). Brenner is shot by a sniper while attempting to escape with Eleven, who overpowers the Army. As Brenner dies, Eleven refuses his pleas to forgive him for the way he treated her.

In season one, he vanishes somewhere near "Mirkwood" after encountering the monster that escaped through a rift to the "Upside Down", an alternate dimension discovered by the Hawkins Laboratory scientists. Schnapp was promoted to series regular for the second season, after recurring in the first.

In season two, he began to experience flashbacks to his time in the Upside-Down, with visions of a large shadow monster trying to attack him. The monster eventually possessed Will, and was later dubbed by Dustin as "The Mind Flayer". Joyce, Mike, Jonathan, and Nancy were able to drive the Mind Flayer out of Will, returning him to normal.

In season three, his friends' preoccupations with their girlfriends lead to Will feeling like the odd-man-out. His link to the Mind Flayer helps the group know when it is active. At the end of the season, he moves out of Hawkins with Joyce, Jonathan and Eleven.

In season four, Will, Mike, Jonathan, and Argyle recover Eleven and help her build a sensory deprivation tank through which she can fight Vecna. Upon returning to Hawkins, which has been ravaged by a series of faults opened by Vecna from the Upside Down, Will begins feeling the Upside Down's influence again—recognizing Vecna as the presence he felt all along.

Schnapp has confirmed that Will is gay and is attracted to Mike. The show has hinted at this through the first three seasons, but it was made more apparent during scenes in the fourth season. Will tries to boost Mike's confidence that they will find Eleven as they drive to the Nina project site.

When Vecna possesses Max, she retreats to the safety of her favorite memory—the 1984 Snow Ball, where she and Lucas first danced—but this fails to work for long. Eleven enters the fray within Max's mind, but she is overpowered by Vecna, who begins killing Max. At the last second, Eleven manages to save Max from Vecna's final blow.

Owens recruits Eleven to participate in the program after a string of murders in Hawkins; she initially revolted after learning of Brenner's involvement, but the brief resurgence of her powers during an escape attempt convinces her to stay. The project ultimately succeeds in restoring Eleven's powers, but U.S. Army forces led by Lt. Col. Jack Sullivan storm the facility, believing Eleven to be responsible for the Hawkins murders.

Vecna

* Portrayed by Jamie Campbell Bower (adult) and Raphael Luce (child)
* Appears in: ''Season 4''
* Status: Alive

Vecna is a murderous being in the Upside Down, who first appears in season four. He preys on individuals reeling from past traumas, and his method of killing involves inducing nightmarish visions before telekinetically breaking their bones and imploding their skulls. He operates out of the Creel House in the Upside Down. He is revealed to have been the main antagonist of the series, being responsible for the events that terrorized Hawkins in the previous seasons, all the way back to Will's disappearance in Season 1.

Vecna is revealed to be Henry Creel, Victor Creel's son who was born with telepathic abilities. Henry grew up with a deeply misanthropic view of humanity after being ostracized throughout his childhood. He came to resent his family for their perceived hypocrisy, having learned that his father mistakenly bombed the home of an innocent family during World War II. In the 1950s, he terrorized and murdered his mother and sister in his family's house using his powers, but the exertion put him in a coma while his father was arrested for the murders and placed in a psychiatric institution. Henry was placed in the care of Dr. Brenner, who made him test subject One in Brenner's attempts to replicate Henry's powers in other children. As an adult, Henry was made an orderly at Hawkins Lab to help oversee Brenner's experiments on a number of superpowered children, including Eleven. Brenner placed an implant (dubbed " Soteria") in Henry's neck that suppressed his powers. In 1979, Henry befriended Eleven amidst her being bullied by other subjects, and pointed out to her that she and the rest of the lab's occupants were prisoners. Sympathizing with Henry's plight after witnessing him being punished by Brenner, Eleven destroyed the Soteria implant, restoring his powers. Henry massacred all the other children and most of the lab's staff and attempted to kill Eleven after she refused to help him eradicate the rest of humanity. Eleven overpowered Henry and sent him into the Upside Down, where he became disfigured by lightning injuries and prolonged exposure to its toxic environment. Henry discovered various creatures residing in the realm, and used his powers to control them, the Mind Flayer being the result of his manipulations.

In 1986, after spending several years remaining dormant and growing stronger while controlling the Upside Down, Henry begins terrorizing Hawkins himself, murdering several Hawkins High School students, including Chrissy Cunningham, Fred Benson, and Patrick McKinney. Dustin and Eddie dub him "Vecna" based on his similarities to the '' Dungeons & Dragons''s character of the same name. Vecna nearly kills Max until her friends find a way to break his influence using music. He later possesses Nancy, reveals to her his past, and then shows her a vision of the future where Hawkins is torn apart by rifts before releasing her. Nancy and her friends deduce that Vecna needs to open four gates to the Upside Down to enact his plan, three of which have been spawned at the site of each of his murders. Max attempts to bait Vecna while her friends travel to the Upside Down to kill him. Eleven enters Max's mind and confronts Vecna, who reveals himself as the mastermind behind the Upside Down's past attacks on Hawkins. Vecna possesses and kills Max before Eleven overpowers him, while Steve, Nancy, and Robin severely injure his physical form before he escapes. Though Eleven revives Max, her brief death opens a fourth gate to the Upside Down, causing rifts to tear through Hawkins, allowing the Upside Down to begin infiltrating the town.

He lives with his uncle, Wayne Munson, and while the two are not seen onscreen together, it is made clear that their relationship is very close.

While selling drugs to Chrissy Cunningham, Eddie watches as Vecna telepathically kills Chrissy. He Screams In Horror And Runs Away. Realizing that the authorities will not believe his story and is later located by Dustin, Steve, Max, and Robin, who explain to him the existence of the Upside Down. The local police name Eddie as their chief suspect in Vecna's murders. The school basketball team, led by Chrissy's boyfriend Jason Carver, attempts to hunt him down, with Jason believing Eddie to be the leader of a Satanic cult. The group of friends realize they must work to clear Eddie's name. When they locate a new gate to the Upside Down in a lake, he dives down after Steve gets pulled in and experiences the Upside Down for the first time. In preparation for the final battle against Vecna, the group purchases and crafts weapons, with Eddie and Dustin re-entering the Upside Down to distract the demobats protecting Vecna's lair. As part of the final plan, Eddie plays Metallica's " Master of Puppets" on his electric guitar. He later stays behind and sacrifices himself to further fend off the demobats. After Vecna's gates create large rifts that tear through Hawkins, the town still believes Eddie is responsible for the murders. Dustin meets Eddie's uncle and assures him that Eddie was a hero who died protecting the town.

Creatures of the Upside Down

Mind Flayer

Introduced in the second season as a malevolent semi-corporeal entity that resides in the parallel dimension known as the Upside Down, where every living thing in that reality serves as an extension of the Mind Flayer's hive mind and acts on the entity's desire to spread itself to Earth. The events of the first season allowed the Mind Flayer to terraform Hawkins secretly through Will Byers, who was infected during his time in the Upside Down and had unknowingly brought incubated Demogorgons with him.

In the second season, the Mind Flayer's existence was revealed as it implanted a piece of itself into Will through visions, while using adolescent Demogorgons to eliminate anyone who interfered in the terraforming. While the others managed to close the gate to sever the Mind Flayer's foothold, its ethereal fragment took refuge at Brimborn Steel Works after being "exorcised" from Will. During the events of season three, a new Gate opened by Russians allowed the Mind Flayer to have its isolated fragment create an organic vessel by infecting and possessing living beings and absorbing their entire biomass. The Mind Flayer nearly succeeded in killing Eleven, only to lose its foothold when Joyce and Hopper infiltrated the secret Russian laboratory and closed the new gate.

In the fourth season, the Mind Flayer is revealed to have been shaped and controlled by Henry Creel (Vecna), who discovered the entity as a formless mass in the Upside Down (after being sent there by Eleven) and morphed it into its spider-like appearance, owing to his childhood fascination with black widows. Hopper, Joyce, and Murray discover another fragment of the Mind Flayer inside a Russian research facility in Kamchatka, where it eventually breaks free and animates the other Demogorgons inside the facility. Hopper and Murray manage to kill the remaining creatures.

Demogorgons, Demodogs and Demobats

Predatory creatures from the Upside Down that serve as the Mind Flayer's initial invasion force, are murderous and violent with limited intelligence. Demogorgons start off as slug-like creatures that are incubated in a victim's body, growing into a tadpole-like creature and gradually molting into an adolescent form called a "demodog" before fully maturing. An adult demogorgon, played by Mark Steger, appears after a gateway to the Upside Down was accidentally opened in Hawkins, and demonstrated an apparent ability to create random rifts between the Upside Down and the normal world. Though that demogorgon, called the Demogorgon, was eventually destroyed, its abduction of Will Byers allowed the Mind Flayer to unleash a swarm of adolescent demogorgons upon Hawkins before they were all killed when their connection to the Mind Flayer was severed.

The end of the third season reveals another adult demogorgon, eventually called the Russian Demogorgon, being held captive by the Russians at a prison camp in Kamchatka, where prisoners are sometimes executed by being fed to the creature. In the fourth season, Hopper and his fellow prisoners are forced to fight the Russian Demogorgon. Hopper uses a flaming spear to hold back the creature while it ravages most of the other prisoners, while Joyce and Murray help him escape alongside Dmitri Antonov, a guard he bribed and befriended. The group discovers a number of demogorgons (as well as a fragment of the Mind Flayer) under study inside the prison. The creatures are accidentally let loose during a firefight between the prison guards and the Russian Demogorgon, but Hopper and Murray kill the remaining creatures and escape Russia.

A variant with wings like a bat called the Demobat also exists. The variant was introduced in the fourth season when Steve Harrington went through Watergate, the gate at the bottom of Lover's Lake which opened up when Patrick McKinney was killed by Vecna. The Demobats attacked Steve, but were fended off by him, Nancy Wheeler, Robin Buckley and Eddie Munson. Later, Eddie played " Master of Puppets" to distract the Demobats and ended up being killed by them. After Vecna was defeated, they fell to the ground and seemingly died.

The Flayed

A term for Earth-based beings that are possessed by the Mind Flayer, Will Byers being the first case during the second season until an ethereal fragment of the Mind Flayer was purged from his body. The isolated fragment later began possessing rats and eventually humans during the events of season three, having most of its hosts ingest toxic chemicals so they could gradually be melted down into materials for the Mind Flayer to create a proxy body to act through in its attempt to kill Eleven.
