Well...tastes differ. The ideas are for the most part quite interesting.

Myself I am not a fan of temporary TFs, they always seem pointless to me, as they lack the lifechanging impact of a permanent TF.
As Brande said, iannimate and temporary TFs are not really part of Belial, however, they are some solutions that come close (e.g. the Omnicopier creating living/organic mimicries of inanimate objects) and some magicians, ingenius alchemists and especially demons could perform certain temporary TFs or create a way to make the person turn back to normal.

Furthermore non-Belial ideas and stories are welcome here, too.

I meant Non-Belial actually.

Well as for grotesque creatures, here's what I'm thinking of (although none of them are sexual like Belial though).

I think you get the idea which the theme would be turning beautiful attractive women into extremely grotesque vomit inducing monsters/creatures to shock the audience of course though the only sexual thing is the disrobing presenting their nude bodies (to see how beautiful/attractive they look before) and the sensation of transformation. Of course though instead of mutations, I think it would be like magical morphings which would enable the possibility of them returning to their normal forms.

Well I also have other bizarre ideas remember the factory idea? Well what about a Toy Factory where women voluntary transform themselves into dolls (I mean not sex dolls but rather actual porcelain dolls), puppets, teddy bears, rocking horses,  toy soldiers, etc which they disrobe and they step into the strange funhouse like machine which their moans of pleasure are audible and out comes the object from the conveyer belt.

Also a "carnival"  which women transform themselves into carnivle theme stuff like Clown like creatures (which group of women disrobe and they slowly sink into quicksand like 'bubbling' ball pit like this while they sink they first act playfully, laughing  and commenting on the sensation while they're sinking and further down they go they erotically orgasm or asking each other "are you enjoying this?" with a few "oh yes/yeah" until they are fully 'submerged' which balls rumble and out comes the klowns...well this is inspired by a scene from "Killer Klowns from Outer Space" where it's hinted that some of the kidnapped women turned into female klowns except in the story though, they are not female clowns but rather resemble cartoony clowns with oversized mouths, hands, feet, wearing bizzare clown attire), Balloons, Freak Creatures, etc

Lastly, Women actors volunteer in a bizzare show which they are transformed into creatures resembling these or telltubby like creatures which the show is full of surrealism that is not for kids. Well of course like I said before that transformations can replace costumes, props, etc in films, tv shows, etc.

Hmm...well if you do requests, maybe you can write one for me (well that is Non-Belial)? Regarding the same description I gave with the bubbling ball pit being the "Transformation" center and also alternatively have nude women going through a funhouse like machine which they're turned into different set of clowns there as well.

Basically I have a idea of a bizarre carnival where attendees willingly and voluntary transformed into carnival themed things like clowns, balloons, freaks, etc...or maybe strictly stick to bizarre looking looking clowns.

Speaking of Morben, anything new flowing in that beautiful brain of yours?

Well, as for clown tales, here is my collection of stories on deviantart that fit that mold.

Although probably none of those stories are anything I have in mind though especially anything about willing volunteers disrobing and stepping into some plateform/machine/etc to be transformed (perhaps the same with the magic show)....or maybe you can write one though or maybe you could point one out.

Well not only it's a needle in a heystack and I checked each one and I think I've seen none of what I was thinking of though (unless I'm missing something).

You know, I think I may have a request, maybe you could write a magic show related story with one of the transformations being clowns (separate from Clowntopia).

Or maybe you can write a another clowntopia story that fully involves willing volunteers disrobing nude before transforming if it's possible...

BTW darkdonny I found this which is very similar what I'm talking about: http://tf-circus.deviantart.com/gallery/

It's kinda like that but except though, the volunteers disrobe and they step into some fun house like machine or sink into a ball pit which they turn into caricature clowns.
