We're all aware of the way Rule 34 permeates anything and everything, up to and very much including the world of sex toys. It's just that we're also well aware of the uber-jealous way big studios safeguard their precious franchises and their reputation -- if anyone's going to ruin it, it's going to be them, thank you very much.
Does this prospect of rampant lawyerin' from major industry players do anything to deter entrepreneurial sex toy makers from using the likenesses of pop culture characters we all know and love? Evidently not, because people currently have the option to rub their genitals all over ...
Out of all the characters on this list, the Doctor is perhaps the only one whose presence makes at least some inkling of sense. He's been played by enough actors that virtually anyone who's into dudes at all can find one of his incarnations sexy. Even better, his signature weapon / deus ex machina, the sonic screwdriver, is basically a superpowered dildo. Called a sonic screwdriver. It's right there, people! Surely the vast and sticky world of rogue sex toy manufacturers is teeming with buzzing versions of the thing.
Or not. Perhaps fearing that someone would assume they're underachieving, or even worse, that they can't come up with a sexier name than the one the thing already has, no sex toy makers that I could find have taken the bait and created flashing, multi-functioning Doctor-themed vibrators. Instead, here's a goddamned TARDIS butt plug. That ... doesn't even make any sense. Why would you want to stick the hero's clunky vehicle in your butt? Ah, that was stupid of me to ask. We live in a world where Pteranodon porn is a thing, so I suppose I should be grateful that's not an actual replica. Then again, I'm pretty sure someone, somewhere, is shoving a TARDIS scale model up their butt right now, so uh, let's not pursue that train of thought any longer.
And of course that damn Etsy plug is not the only TARDIS-related Doctor Who sex toy out there. Consider the Tickler, which is a custom-designed TARDIS dildo, because really, did you expect anything else?
Somewhere in there, a tiny Peter Capaldi has been screaming "Nooooooooo!" continuously for a decade.
