Joyce Byers (portrayed by Winona Ryder) is the mother of Will and Jonathan Byers and is divorced from Lonnie Byers, the father of her two children. Joyce is a very caring and strong-willed woman who works as a retail clerk at Melvald's General Store in downtown Hawkins. She was born and raised in Hawkins and she attended Hawkins High School with the future chief of police, Jim Hopper, and her Season Two love interest, Bob Newby. In Season Three, she is planning to sell her house and move out of Hawkins, much to the dismay of Hopper who tries to convince her to go on a date with him. Joyce is more interested in figuring out why the magnets in her house keep failing (to the extent that she does not show up to the date that they had planned together) 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, causing his apparent death. She then takes guardianship of Eleven and moves with her and her two sons out of Hawkins three months later.
Jim Hopper (portrayed by David Harbour), nicknamed "Hop", is the chief of Hawkins Police Department. Hopper has lived in Hawkins nearly all his life, having attended high school with Joyce Byers and Bob Newby. He has also been addressed as "Sheriff Hopper," but this is not a correct title. Hopper divorced after his young daughter Sarah died of cancer, which caused him to lapse into alcoholism. For a few years after Sarah's death, he was a cop in "a big city," but the show never states which city. When he had been in the city long enough, he moved back to Hawkins. Eventually, he grows to be more responsible, saving Will Byers from the Demogorgon as well as taking Eleven in as his adopted daughter. In Season 3, he tries to break up Eleven and Mike since their relationship is moving too fast for him, while simultaneously trying to win over Joyce romantically. Through Joyce, he once again gets involved in an investigation regarding the supernatural, which leads them to uncover a Russian conspiracy. He is apparently killed by an explosion caused by a Russian machine used to open a portal to the Upside Down. At the end of season three during the final credits, a scene shows a Russian prison with two guards selecting a prisoner to give to a demogorgon. As they are talking about who to kill, one of the guards orders "not the American", leading to speculation of Hopper's survival.
Michael "Mike" Wheeler (portrayed by Finn Wolfhard) is the son of Karen and Ted, younger brother of Nancy and older brother of Holly, and one of three friends of Will Byers. Mike is an intelligent and conscientious student who is committed to his friends. In their Dungeons and Dragons party, Mike is their paladin and usually plays the role of Dungeon Master. He develops romantic feelings for Eleven. In Season Two, it is revealed that he has developed a more rebellious streak, likely stemming from missing Eleven. He is the first one Will reveals his apparent flashbacks to the Upside Down to and he accompanies Will, Joyce, and Bob to the lab when Will's health deteriorates. When Eleven reappears, he is joyous, but angry at Hopper for keeping her hidden for the past year. A month later, the two attend the Snow Ball together and share a kiss. The next summer, the two are dating, but Hopper manages to drive a wedge between them as he thinks they are spending too much time together. With additional meddling from Max, Eleven eventually breaks up with Mike, but the two later get back together. Mike nearly tells her that he loves her but struggles to find the right words. When Eleven moves away with the Byers, Mike promises her to keep in contact and schedules visits at Thanksgiving and Christmas. Eleven then tells Mike that she loves him too.
Eleven (portrayed by Millie Bobby Brown) was born as Jane Ives and grew up in Hawkins Lab where she was experimented on by scientists until the beginning of season one. Eleven has telekinetic and telepathic powers, which allow her to control things with her mind. She escaped the lab and befriended Dustin, Will, Mike, and Lucas, where she was given the name Eleven due to the 011 tattoo on her arm. In season two, Jim Hopper became a father figure to Eleven while searching for her biological mother, culminating in her adoption by Hopper at the end of the season and was named Jane Hopper. In season three, she is dating Mike, to Hopper's chagrin, and is pursued by the Mind Flayer that had been let loose by the Russians opening a gateway to the Upside Down. After Hopper dies when the portal is closed, Eleven leaves Hawkins with the Byers.
Dustin Henderson (portrayed by Gaten Matarazzo), a friend of Mike, Will and Lucas, is a highly intelligent and studious boy whose cleidocranial dysplasia causes him to lisp. In their Dungeons and Dragons party, Dustin is the bard and has arguably the most extensive knowledge of the game, particularly the monsters. He had a crush on Nancy Wheeler, while both he and Lucas had feelings for Max in the second season, but Lucas and Max ultimately end up together. He befriends Steve Harrington in the second season, 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, he is able to get a girlfriend, Suzie, that he claims is a genius and is "hotter than Phoebe Cates." Dustin's friends are skeptical whether she actually exists as he is unable to get in contact with her over his makeshift radio tower. Dustin instead discovers the coded Russian transmission and goes to Steve with the information instead of his friends due to their skepticism over Suzie. He later proves Suzie's existence when he contacts her for Planck's constant.
Lucas Charles Sinclair (portrayed by Caleb McLaughlin) is a friend of Mike, Will and Dustin, and older brother to Erica. Lucas is initially wary of Eleven, yet befriends her later on. In Season Two, he becomes a love interest for Max. In their Dungeons and Dragons party, Lucas is the ranger. He is very skilled with the use of a slingshot, which the party calls "The Wrist Rocket"; in the first two seasons, the slingshot is used for comedic effect as a hopeless last-minute defense, but in the third season, is used to actually save the team from danger.
Nancy Wheeler (portrayed by Natalia Dyer) is the teenage daughter of Karen and Ted, older sister of Mike and Holly. Nancy is initially something of an outcast at school until popular student Steve Harrington takes an interest in her. Their relationship lasts until the beginning of season two when she starts dating Jonathan Byers after a little help from conspiracy theorist Murray Bauman. She is very proficient with firearms, despite a noticeable lack of training or practice. She has been seen using pistols, revolvers, rifles and shotguns. In the third season, Nancy and Jonathan work as interns at the Hawkins Post, where Nancy is subject to sexist harassment from her male superiors. She and Jonathan are eventually fired for pursuing a story against their editor's wishes, but Nancy continues to investigate the case, which leads her to multiple encounters with the Flayed being controlled by the Mind Flayer from the Upside Down.
Jonathan Byers (portrayed by Charlie Heaton), the older brother of Will Byers and the son of Joyce Byers, is quiet and considered an outsider at school. He is an aspiring photographer, and very close with his mother and brother. He starts dating Nancy at the end of Season 2. He and Nancy become interns at the Hawkins Post in Season 3, but are eventually fired by their editor. He moves out of Hawkins with Joyce, Will, and Eleven at the end of Season 3.
Karen Wheeler (portrayed by Cara Buono) is the mother of Nancy, Mike, and toddler Holly, and wife of Ted. She is a loving mother who remains largely clueless about her children's activities. At the end of the second season and beginning of the third, she develops a sexual attraction towards Billy Hargrove, partly out of boredom with her family life, but ultimately decides against acting on these feelings. She encourages Nancy to continue pursuing a story she was fired for working on against her editor's orders.
Martin Brenner (portrayed by Matthew Modine) is the head scientist of Hawkins Laboratory and the experiments performed there, serving as one of the two main antagonists of the first season. He is callous and manipulative scientist, having abducted Eleven from her mother, whom he later subjected to electroshock therapy to destroy the woman's mind. Brenner then put Eleven through numerous experiments before she escapes after using her to establish a link to the Upside Down. He 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 assumed Brenner is still alive during his attempt to plea for his life to Eleven and Kali.
Will Byers (portrayed by Noah Schnapp), the younger brother of Jonathan Byers and the son of Joyce Byers, is a shy, kind, and often timid boy. In the group's Dungeons and Dragons party, Will is the cleric, but later occasionally plays the role of Dungeon Master. In November 1983, he vanishes 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. He is possessed by the Mind Flayer from the Upside Down in season two. In season three, his friends' preoccupations with their girlfriends leads to Will feeling like the odd-man-out. His link to the Mind Flayer helps the group detect when it, or one of the Flayed, are active.
Maxine "Max" Mayfield (portrayed by Sadie Sink) is Billy's younger stepsister, an avid skateboarder, and the tomboy of the group who catches the attention of both Lucas and Dustin. While she never played Dungeons and Dragons, she calls herself the "zoomer" of the party, despite Mike's persistence that the term is made-up. She claims that the role of the "zoomer" is to transport the group from place to place. In the second season, while she is driving a car very proficiently, she says to Mike, "See? Zoomer." In season three, she and Lucas are dating, and she and Eleven become close friends.
Steve Harrington (portrayed by Joe Keery) is a popular student at the high school. He initially tries to develop a relationship with Nancy Wheeler and ostracize Jonathan Byers, though he comes to regret that later. Keery was promoted to series regular beginning with the second season, after recurring in the first. Steve then played a more prominent role, developing a friendship with Dustin, and becoming the "mom" of the main group of kids due to his protective behavior. Steve is the owner of what the friends call "the bat", a baseball bat with multiple large nails driven into the head of it, made by Jonathan to fight the Demogorgon. While it did not have any lasting effect against Demogorgon, it was able to kill some Demo-Dogs. In season three, he works at Starcourt Mall at Scoops Ahoy with former classmate Robin Buckley. Steve, Dustin, and Robin then discover the secret Russian base under Starcourt Mall.
Billy Hargrove (portrayed by Dacre Montgomery) serves as the secondary antagonist of Season 2 and the joint main antagonist of Season 3, along with the Mind Flayer. He is careless, rash, and verbally abusive to his stepsister Max – a consequence of the physical abuse he himself suffers from his very abusive father. He is rather promiscuous, often sleeping with bored housewives. In Season 3, he becomes the unwilling catalyst for the Mind Flayer. Flashbacks reveal that Billy's mother left when he was young due to his father's abuse. Eleven later reminds Billy of his mother, allowing him to break free from the possession, and sacrifice himself to save Eleven from the Mind Flayer. In his last moments, he apologizes to Max for everything he has done.
Bob Newby (portrayed by Sean Astin) is a former classmate of Joyce and Hopper, who runs the Hawkins Radio Shack, and becomes Joyce's boyfriend in Season 2, putting him at odds with Hopper. While he, Hopper, an unconscious Will, Mike, Joyce, and Owens were trapped in Hawkins Lab with the power out, he volunteered to reset the breakers and unlock the doors. After succeeding, he was attacked by a killed and eaten by Demo-Dogs in front of Joyce. He is included in flashback scenes in Season 3.
Dr. Sam Owens (portrayed by Paul Reiser) is a United States Department of Energy executive who replaces Brenner at Hawkins Laboratory. Owens is as committed to science research and stubborn as his predecessor, but much more empathetic to the residents of Hawkins. Owens is in charge of studying and treating Will's lingering traumatic episodes from the Upside Down. He leaves his post at Hawkins Lab at the end of Season 2 after it is attacked by monsters at the Upside Down, and provides Hopper with a birth certificate for Eleven naming her as Hopper's adopted daughter. In Season 3, Hopper tries to contact him to send back up and he briefly appears in the finale where he discovers the Russian lab used to open the gate to the Upside Down.
Robin Buckley (portrayed by Maya Hawke) is an "alternative" girl who works alongside Steve at Scoops Ahoy, the Starcourt Mall ice cream parlor, and introduced in the third season. Robin is sarcastic and bored with her job and teases Steve about his inability to flirt with girls, but she is able to decode the Russian radio message and finds the base along with Steve, Dustin, and Erica. While initially stating that she was obsessed with Steve in high school, the influence of truth serum reveals that she actually pined for the attention of one of Steve's many admirers, revealing she is a lesbian.
Erica Sinclair (portrayed by Priah Ferguson) is Lucas' 10-year-old sister. Introduced in the second season as a recurring character, she was promoted to series regular in the third season. She aids Dustin, Steve, and Robin in infiltrating the Russian base beneath Starcourt Mall. During these events, Dustin convinces Erica that, like himself and his friends, she is a nerd and that she should embrace that. At the end of the third season, she is given Will's Dungeons & Dragons manuals.
The principal antagonist of the series, introduced in the second season as a malevolent non-corporeal entity that resides in the parallel dimension known as the Upside Down where every living thing on that reality serves as an extension of the Mind Flayer's hive mind and act on the entity's desire to spread itself to Earth. The events of the first season allowed the Mind Flayer to secretly terraform Hawkins 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 is revealed as it implanted a piece of itself into Will while using the Demodogs to eliminate anyone who interferes in the terraforming. While the others manage 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 a vessel by infecting living beings and absorbing their biomass. The Mind Flayer nearly succeeded in killing Eleven, only to lose its foothold when Joyce and Hopper snuck into the secret Russian laboratory and closed the new gate.
- Demogorgons: Predatory creatures from the Upside Down that serve as the Mind Flayer's initial invasion force, 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 a adolescent form called a "Demodog" before fully maturing. An adult Demogorgon, played by Mark Steger, appears in the first season after a gateway to the Upside Down was accidentally opened in Hawkins. Though that 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 Flayed: A term for Earth-based beings that are possessed by the Mind Flayer, Will 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 an proxy body to act through in its attempt to kill Eleven.
