Well I like all of them, except for Rugrats.

Ben 10, yeah I could see that working pretty well.

HTTYD, again, I could also see this working pretty well.

Incredibles, I like both of the ideas here, personally I quite enjoy regression.

Zootopia, interested, though I think i've seen this done before.

Walking Dead, eh, I'm not sure I'm too interested in diapers in the zombie world. It just doesn't mesh well in my mind.

Ben 10: the main idea here being that using the Omitrix has some side effects, namely making him incontinent. So Ben suddenly has to deal with wearing diapers, and having his cousin tease him on their adventures. Perhaps Gwen is made to be his changer, and they can get into a relationship at some point.

HTTYD: This one came about because there are no toilets on dragon back, so riders take to wearing them on long flights. Eventually it became a fashion statement to wear them amongst riders, even on the ground. I was thinking a romance between Hickup and Astrid for the main plot here.

Rugrats: Just a slice of life for this one. The only difference I would make would be to age them up, and say that potty training is much later in this world.

Incredible's: This one was based on the idea of diapers being a part of their costumes, since there's no time for potty breaks in battles. Dash thinks there neat, but Violet doesn't like them and tries to avoid using them. It comes to a point in the story where she had to use them, and finds them to be alright.

The other idea was to have syndrome forcibly regress and baby the kids, as a further means of humiliating the family.

Zootopia: A world where predators wear diapers, since they aren't potty trained. I have a bigger story for this one, so just say if it interests you

Walking Dead: Based on the Tell Tale game, with Clem. She'd regress as a coping mechanism during the apocalypse, and that's where diapers and babyish things come in.

Sure, I can hear the ideas for them.

Cool. Want to hear the ideas behind all of them, or just pick an idea now, and I'l elaborate?

Ben 10, How To Train Your Dragon, Rugrats, Incredibles, Zootopia, maybe Walking Dead. Are all things I could get behind at the moment.

Well, here's a non-exhaustive list:

Arthur
2012
Avatar (Air bender and blue people one)
Ben 10
Matilda
bioshock
Bridge to Terabithia
Game of Thrones
How to train your dragon
Inside out
Jungle book
Last of us
Legend of Korra
Lion king
Rugrats
The Incredibles
Walking Dead
Yu Gi Oh GX
Zootopia

Franchises your into.

I know, but I think it did come up at one point. I thought it might address the problem of the plot not going anywhere.

Can I ask what you mean by cannons? Just franchises I'm into, or did you mean seperate ideas for the franchises?

We never did a potty training aang rp. We did an rp where he and katarra both use diapers but it didn't really go anywhere.

What other canons are you into so we can perhaps explore this?

Well I know I liked the Arthur one we did. I also liked avatar, and the idea of potty training aang.
