I barely know anything about Gravity Falls (any knowledge I have I skimmed through threads on /co/, but I have to address other things in these posts.
>>106617033You're correct that Simpsons and Futurama share a universe, Archie did show up on the Simpsons, and Archie did crossover with Glee.
>Simpsons crosses with Rick and Morty, which crosses with GF I'm reading this and it sounds like
https://rickandmorty.fandom.com/wiki/Gravity_Falls Rick and Morty and Gravity Falls don't occupy the same dimension. Rick and Morty may have counterparts in the Horrorverse, but if you include Gravity Falls then the Rick and Morty show doesn't take place in the Horrorverse. Hell, for all we know, the Horrorverse Rick and Morty might've been killed off.
Additionally, Simpsons crossing over with Rick and Morty doesn't mean they're in the same universe, just that Rick and Morty ended up in their dimension.
>>106618414>Yet, they all share a Multiverse, and Archie’s crosses over with Sharknado, Predator and the PunisherThe Predator crossover is connected with the Punisher crossover (because Veronica has a photo of her and Punisher in one panel), but the Sharknado one isn't because Cheryl was killed in the Predator crossover, and Sabrina had a completely different look/personality in the Predator crossover while she was more like the Archie version in the Sharknado crossover.
>>106618856Afterlife with Archie doesn't connect with Archie. In fact, all the horror titles are separate universes from each other, there's that one where Jughead's a werewolf and Betty's a werewolf hunter, and the one where Veronica's a vampire, and the one with a darker take on Sabrina that also has Betty and Veronica as witches. It also implies all of them are teens in the 1960's. That Sabrina series also had this connection.
If you were to include a version of Archie in the Horrorverse I'd probably recommend picking one from the Horror line, leave the rest to be in their own worlds.
