so basically, the first three pretty little liars shows originally had NO correlation to riverdale and archie, but because the showrunner and writer of pretty little liars original sin also wrote riverdale, he couldn’t help himself and decided to make them in the same universe. so riverdale, chilling adventures of sabrina and katy keene have shared the universe since the comics. the chilling adventures of sabrina kind of like implied that sabrina and her family were related to madison montgomery from coven, which isn’t confirmed but it’s a fun theory that has been around since the chilling of adventures came out. the way that predator, alien, blade runner, teenage mutant ninja turtles, the mcu, DC, sonic, glee, sharknado and halloween is connected to riverdale is the fact that they all had crossovers with the archie comics, or they’re in the same universe as something that crossed over to archie (for example, alien and blade runner didn’t crossover with archie, but predator did, and predator, alien and blade runner share a universe). so, my theory is that because riverdale is based of archie, that these crossovers from the comics could also mean that these characters and universe exist with in the riverdaleverse. halloween had a little crossover with archie, and i think that the events of the first halloween movie might have been based off actual events with a real michael myers and laurie strode in the riverdale pretty little liars verse, because halloween is a movie in pretty little liars original sin. so, halloween is connected to psycho, texas chainsaw massacre, friday the 13th, a nightmare on elm street, child’s play, and the rise of leslie vernon — both halloween and psycho share the same character; sam loomis. michael’s mask was seen in bride of chucky in an evidence locker along with freddy’s glove, jason’s mask, and leatherface’s chainsaw. haddonfield and michael myers are referenced in the rise of leslie vernon. michael is seen in an ad meeting chucky, and haddonfield is referenced in chucky 3x03.
texas chainsaw massacre is connected to friday the 13th, child’s play, a nightmare on elm street, and the hatchet films. jason and leatherface cross over in a comic series, his chainsaw was seen in bride of chucky, a comic of a nightmare on elm street shows a newspaper with the headline “leatherface returns”, and the actress caroline williams, who played the final girl in texas chainsaw massacre 2, plays a character in hatchet 3, and she says that her character in hatchet 3 is a continuation of her character from texas chainsaw 2.
chucky visits the amityville house in chucky 3x03. that’s it.
friday the 13th is connected to a nightmare on elm street, evil dead, the rise of leslie vernon, and the hatchet films. freddy vs. jason happened (because in the final friday: jason goes to hell, jason’s mask is pulled down to hell by freddy), jason crosses over with both freddy and ash in the freddy vs jason vs ash comic series, the necronomicon from evil dead is in jason goes to hell (and the director said that pamela voorhees used it to bring jason back to life, but couldn’t explicitly say it in the movie because new line cinema didn’t have the rights to evil dead. basically jason is a deadite.), and hatchet 2 references jason as an urban legend.
evil dead is connected to a nightmare on elm street, pumpkinhead, and the re-animator. freddy’s glove is seen in the cabin in evil dead 2. the necronomicon shows up in both pumpkinhead 2 and the comic pumpkinhead #1-5. army of darkness and the re-animator crossover in a comic.
a nightmare on elm street is connected to child’s play, the rise of leslie vernon, and friday the 13th. in the child’s play comic, child’s play #2, freddy is referenced as a “dream killer who has plagued springwood, ohio for years”. the rise of leslie vernon references elm street and freddy as an existing killer. in the friday the 13th game, it is said that tommy jarvis spent time in westin hills (the psychiatric hospital from a nightmare on elm street 3), and neil gordon, who was a doctor in the same movie, is name dropped — tommy was mentioned to wake up with cuts on his body during his stay at springwood, hinting that freddy was also haunting his dreams. elm street is also mentioned in chucky 3x03.
hellraiser is connected to child’s play, the rise of leslie vernon, and pumpkinhead. in bride of chucky, chucky says that a man looks familiar after throwing pins in his head, which could suggest that chucky saw pinhead during one of his deaths and trips to hell. in the rise of leslie vernon, eugene (who is also referenced to be billy from black christmas) owns a lament configuration. in pumpkinhead: ashes to ashes, doc fraser owned several lament configurations.
child’s play is connected to the rise of leslie vernon, the re-animator, and evil dead. in the rise of leslie vernon, chucky is referenced to as an existing killer. damballa is referenced in the re-animator comic, re-animator: dawn of re-animator #2, where he was a part of a ritual to bring someone back to life. a mirror dimension vision of damballa appears in the comic evil dead 2: dark ones rising #5, appearing as lightning similar to his child’s play appearances.
the rise of leslie vernon is also connected to friday the 13th, because in friday the 13 the game, tommy is referenced to have spent time in the town of glen echo. hatchet 2 also refers to leslie vernon as an urban legend.
saw is connected to the rise of leslie vernon, a nightmare on elm street, friday the 13th, halloween, and texas chainsaw. in the comic, before the mask: the return of leslie vernon #3, the jigsaw masks are referenced. in #4, there’s pictures representing a saw, a spiral, and the billy puppet in a character’s office as he has a conversation with john kramer (aka jigsaw), and john later appears with freddy, jason and michael. in texas chainsaw 3D, there’s a character wearing the jigsaw robe, pig mask and carrying a fake chainsaw.
so basically the mf who wrote riverdale and pllos didn’t think any of it through when he wrote about pllos being in the same universe of riverdale.
