I apologise in advance to the people who are unable to be featured in this post.
Let us begin!
Joyce Byers- Primal
She lives kind of out of the way compared to the other characters and is very suspicious of a greater power causing weird things to occur in the town of Hawkins and investigates this diligently, getting several other characters involved in this. Such as…..
Jim Hopper- Edvard
Jim Hopper- Edvard
Jim Hopper is the local police chief. He lays the law of the land, and while some find him corrupt and irritating, he gladly helps Joyce Byers with her investigation despite people detailing Joyce as insane.
Mike Wheeler- BohemianRhapsody
Mike is a kid who lives in a pretty typical suburban white household. He, like his friends Dustin, Will, and Lucas enjoy science and dungeons and dragons. His personality is as the more practical of three. He is also the one who took care of and eventually formed a close relationship to Eleven.
Eleven- Delora
Eleven was raised as a science experiment and contained in a lab, but eventually escapes. When Mike finds her in the woods she starts out relatively clueless of the outside world but as the plot goes on she learns more and more, and even discovered she had superpowers. By season 3 she is in a relationship with Mike.
Lucas Sinclair- Xadem
Lucas is Mike's friend and has similar interests to Mike. Unlike the rest of the group, he is more in tune with popular social trends and is generally "more hip". In season 2, he develops a relationship with Max.
Max- Scarlett
Max is the other female in the group. Her personality is more sassy and sarcastic as opposed to Eleven's more serious and straight to the point attitude.
Dustin- TPG
Dustin is the nerdiest of his friend group and routinely introduced to them his latest scientific ideas and inventions. His social skills are the least developed of the three, which causes a rift in season three with his two other friends when they get girlfriends. Despite this, he still managed to snag a girlfriend at science camp and plays a large part in saving the day during all seasons.
Turncoat- Will Byers
Will is the character that triggers the plot of season 1 by being kidnapped by the demigorgan and is largely missing in this season, but in season 2 he is plagued with spontaneous visions by the mind flayer, which slowly takes him over. This is partially defeated but continues into season three, where he is implied to be gay.
Steve Harrington- Tryptamine
Starting out as the high school Chad player in season one, his arrogant attitude proves to be his downfall and he loses his girlfriend Nancy to Jonathan in season two. Despite this, Jonathan keeps living life and settles on being an ice cream scooper, repeatedly trying to game chicks like in his glory days. He even tried to get with his co-worker, Robin…. But she turns out to be gay. He eventually concludes: "fuck these bitches".
Robin- Blanc
Robin is Steve Harrington's female coworker who he pursues and discovers is gay.
Martin Brenner- BillyB
Martin Brenner is the deranged mad scientist that kept Eleven locked up to open the upside down which unleashed chaos into the town of Hawkins.
Billy- Cawk
Billy is a major bully, player, and douchebag. This is due to growing up with an abusive father his whole life. Bad meets evil when the mind flayer takes him over and makes it do his evil bidding until his untimely death at the end of season three.
Karen Wheeler- Luna
Karen is Mike's mother and Billy's teacher, who ends up nearly practicing infidelity with Billy, whom she has a thing for. However, she never ends up going through with it and in the end she stays with her husband.
Nancy Wheeler- Lena
Nancy is Steve's girlfriend in season 1 but cheats on and dumps him for Jonathan in season 2 and by season 3, she is fighting the patriarchy by quitting her job as a petty newscaster and investigating the weird going ons in Hawkins.
Jonathan Byers- Jim
Jonathan starts out on season 1 as a bit of a creeper, but luckily he creeped on Nancy Wheeler, who found his passion for candid female photography and loner vibe endearing and she eventually falls for his charm and dumps her Chad for him. In season 3, they work together at a local news company as coffee pourers, until they quit to investigate the mind flayer's antics.
My grandiose delusions are better than yours.
