The greek gods were Transylvanians.They have changed since that time. But not too much.
The feature was thinly disguised as a morality play to homage The Hays Code-era gangster films.The ones that wouldn't be allowed onscreen unless the Villain Protagonists got their comeuppance (sometimes in no more than the last twenty seconds of the film).
The David statues were prototype Rockies, probably even more brainless than Rocky and made solely to be eye candy.Many people think they might be previous victims of the Medusa ray, but the fact that they are at least half over again the size of a normal or slightly tall human seems to debunk that. This guess makes that feasible.
Brad and Janet are meant to be.That's why all the potential sequels never got off the ground - they all counted on Bran and Janet being apart.
Transylvanians managed to intercept old B Movies on TV signals and mistook them for actual life on earth.The way Transylvanians dress and act seems to either resemble B movies so closely that its possible they strike a chord with something in Transyvanian culture. Some of them came to earth expecting what they saw in the movies and were distressed to find a bunch of Brad-and-Janet-like Muggles.
RHPS is actually an Educational Film for TransylvaniansThe criminologist is giving a lecture on the dangers of interacting with humans. Intended as a Scare 'Em Straight or even a political statement.
The Criminologist is a Transylvanian living among humans, able to travel back to Transylvania at a moment's notice.Or, you know, he could be a Time Lord.
Columbia's verse in "Time Warp" is describing how Frank recruited her.This assumes she is human, of course. He may also have put her through tests or given her a gift that granted her Type V or VI Immortality, if the verse is saying that time literally means nothing to her any more rather than that the hedonistic culture of Castle Frank N. Furter means she no longer cares about the future.
Continuing the above theory, Columbia survives the film's end.Alone, betrayed, without a home, without money and immortal, she wanders the countryside until she ends up in the city of Gotham. With no other choice, she turns to a life of crime. After some time, she learns of a supervillain called The Joker, and in him she sees a replacement for the deceased Frank-n-Furter. She partners up with him, taking the name "Harley Quinn".
Rocky Horror Is About Growing Up
Rocky is a Promethean.
Frank N. Furter is somehow connected to the Doctor.I know what you're thinking: "Show X shares a trope or lookalike with show Y, stop spamming the WMG page." But think about it: The Time Warp may be analogous to the TARDIS moving. The mansion may be some sort of disguised TARDIS, or a different model. Frank N. Furter could be a surviving Gallifreyan or something, maybe a Doctor. (Sorry, I'm not totally down with all the Dr. Who history yet.) Columbia is/was a companion.
Magenta is Actually Magenta from Blue's CluesThat's why she owns the dogs - she misses being one herself. One of the Transylvanian machines accidently turned her human. And she stays with Frank and the others because she misses the crazy world that Blue's Clues takes place in, and this is the only subsitute she could find that was almost as insane. And this would also explain why Riff Raff and Magenta look nothing alike even though they claim to be siblings - he's covering for her. He probably doesn't want Frank to know that he turned a dog into a human, so he just claimed that she was his sister. This is also why Magenta really isn't seen as much in Blue's Clues in the newer episodes. If she's seen at all, they simply use a subsitute dog. However, they know that she won't be as convincing as the real Magenta, so they don't have her act much, but just throw her in the background when she's needed. it only◊ makes sense!
Planet Transylvania is in the Fifth Dimension, or vice versa.They're all a bunch of hypersexual singing sociopaths; perhaps Dr. Frank-N-Furter's work on Rocky places him as one of King Fausto's scientists, developing his "zombie army, zombie navy, zombie marine corps"..."you won't be laughing when the zombie space cadets are on the march!"
