[ABDL, Mental Regression, Diapercritters, Diaper Use]

"It's not often that you call for us, Barbara. It's also not often that you show up outside of Gotham. What's the big deal?"

"I could use my Lasso of Truth, if you try to hide the truth from us in any way. Just remember that, Batgirl."

"I would never lie to either of you. Supergirl, Wonder Woman. I just can't help but feel like we might be dealing with something that's a bit too much for just me to handle. And not even Batman's going to be much help here."

Three super heroines found themselves walking through an abandoned facility that had seemingly just appeared out of nowhere. And according to all of the data that Barbara Gordon, alias Batgirl, had managed to compile... It had connections to another world. What other world? She didn't know, but considering the many extra-terrestrial foes that they had once fought against, it would be hard to blame her for wanting to be careful when there was a high probability of intense danger.

Kara Zor-El, alias Supergirl, was one of Batgirl's closest allies and friends. So she didn't even think twice when she received the call for help. Of course she'd lend Barbara a hand, she'd do the exact same for her when push came to shove. But that didn't mean she actually knew what they were dealing with.

Wonder Woman, who otherwise went by the name Diana, had also been called in. Not because of Batgirl's familiarity with her, but rather her close bond with fellow superhero, Batman. And though she was not as pleased to be here as the blonde, she was still more than willing to help. She just needed more information. It was foolish to fight against an enemy they knew nothing about, after all.

Granted, even after hearing everything that Batgirl had to say about the current situation, she still wasn't convinced. Worst case scenario, it was just some criminals from outer space. But she had promised that she would help if she got the information she wanted, and she wasn't about to go back on an agreement like that.

"So, when are the bad guys supposed to show up?" Supergirl asked, looking around while idly floating above her friends. "It really doesn't look like this place's been used recently. Are you absolutely sure that there's supposed to be baddies here?"

"If the crooks in Gotham are to be believed, they got a bunch of tech from this place. That, and there's been a lot of weird stuff that's happened around Gotham lately. Lots of sightings of... Plush animals walking around. Everyone that I've managed to interrogate sound like they've been awake for too long, but it's just weird enough that I can't help but wonder if they were actually speaking the truth."

"Living plush animals." Wonder Woman said, before slowly pointing straight ahead. "You mean like that Kangaroo that's having a nap over there?" She asked the simple question, while pointing out that they had both missed the very obvious elephant in the room. Probably because they were too busy trying to figure out what was wrong with the facility that they didn't stop to think about anything.

Batgirl looked up at Supergirl, who just chuckled and shrugged her shoulders. She didn't know how she missed it, and it wasn't like Batgirl had a good excuse either. "I... suppose that's what we're looking for, yes. Just be careful, we don't know what it can do."

As the three super heroines carefully approached the oversized and very plush looking kangaroo, they immediately noticed that the oversized animal wasn't just cartoonish. No, it was also seemingly made of a material that was patched together and extra soft. Just like the... Oh good lord, that was a diaper around its waist, wasn't it?

Supergirl laughed a bit. "Really, we're dealing with a big diapered kangaroo? Oh, this'll be a great story when I get back to Metropolis!" She chimed, before flying straight at the Kangaroo, intending on giving a little one-two taste of its own medicine.

Only for the Kangaroo to suddenly jolt awake and bounce right out of the way of her attack, complete with a springy sound echoing from the oversized plush animal's body to highlight just how powerful that bounce was. In fact, it was so powerful that Supergirl could barely even keep track of what had just happened.

"Hold on, hold on! I'm not a bad Diapercritter, promise, promise!" The oversized Kangaroo suddenly spoke, proving herself to not only be sentient, but fluent in their language. "You must be some of this world's mightiest heroes! Oh, I've been waiting for you all to arrive, but it was really hard to find a way to get ahold of you! I'm really sorry, I didn't want to scare you or anything, but I had to do some things I didn't normally want to do!"

Batgirl had seen a lot of strange things while patrolling Gotham. Seeing a living and breathing plush animal speak to her and try to justify her actions was a brand new kind of sight, one that made her slightly rub her eyes to make sure that she wasn't seeing things.

"Why do you need us?" Wonder Woman asked, all while pulling forth her lasso. "Because if you're lying about any of this, I can make sure that you'll tell us the truth. And I won't hesitate to string up a plush thing like you." Honestly, she didn't understand the appeal of this creature in front of her. Neither the fact that it was a living animal, nor the fact that it was very clearly wearing an oversized diaper that didn't really mesh with the rest of it. It seemed to cover up the part of the Kangaroo's body where a pouch was supposed to be... And on top of that, the diaper seemed to contrast the rest of the patched aesthetic of the body. Making it look like a creature made of diapers wearing a diaper to add to all the absurdity...

The Kangaroo rapidly waved her hands to try and make herself seem harmless. "I promise, I promise! I would never hurt you, Diapercritters like me don't hurt other people! But I really, really want you to come with me. My King and Queen have been waiting to see what other worlds' greatest heroes are like, so they can try and raise their own citizens to be just as great as you! I promise, that's all that I need you for!"

"Oooh, greatest heroes, eh? That sounds like fun." Supergirl chimed. "So how do we get to that world of yours? Do we gotta fly through space? I mean, I can do that, but I'm not sure if Barbara and Diana can handle that for too long."

Batgirl just pinched the bridge between her eyes. Kara was getting way too into this. But it seemed like her efforts to befriend the kangaroo were rather helpful as well, as a portal opened right behind the oversized Kangaroo within a few moments of the blonde girl asking.

"Well, all you have to do is follow behind me! I'm Hannah, and I help guide people to and from Diapercritter Kingdom!" The oversized Kangaroo, or rather Diapercritter as she kept calling herself, bowed gently as she introduced herself properly. Right before she bounced straight into the portal, beckoning them to follow her.

Wonder Woman narrowed her eyes, especially as she watched Supergirl fly inside. "I don't like the sound of any of that. But I don't want that thing to cause any more problems than it already has." She said, sprinting into the portal to make sure that Supergirl didn't cause any problems by following the Diapercritter all on her own.

With no other real options, and the fact that she didn't want to leave Diana and Kara to potentially get manipulated by an oversized diaper, Batgirl ran in as well. She just hoped that they weren't doing something they shouldn't. Because there was no way that she was going to be able to explain a set of diapers glued to their waists to Bruce without the man refusing to speak to her for weeks.

Just as quickly as she had run through the portal, she appeared unscathed on the other side. In a land that was not just as pastel colored as the oversized kangaroo, but also just as soft and made from the exact same material. Literally, everything seemed to be made of diapers. No matter where she looked, it all seemed patched together like that. Whether it was the sky or the ground or any of the structures dotting the landscape...

"Welcome to Diapercritter Kingdom, Heroes!" Hannah cried out, bouncing happily on her extra springy feet and even landing on her diapered posterior and bouncing up even higher every few bounces. All while smiling from ear to ear, a feat that was only truly possible thanks to her unique physiology. "Now, let's not delay! My King and Queen have been waiting for your kind for so, so long!"

Just like that, the Diapercritter jumped off without even missing a beat. And all that they could do was follow after her, because the portal that led back to their world had already shut off. They were sorta trapped here, with very little they could actually do to make their experience any better if they had already grown sick of the aesthetic.

Not that Supergirl cared that much. She actually loved how it looked! All this softness, all this lovely color! It was a wonderful sight to behold! That, and she could see lots and lots of big plush animals just like the kangaroo! Well, they were Diapercritters too, weren't they? She actually started to wonder what it might be like to be one, to be a living diaper...

Wonder Woman was less enthused as she followed the path. All while slowly eyeing the many animals that they passed by. Just like the Kangaroo, they were extremely oversized. Not to the point where they towered over the trio, but they were way bigger than they needed to be. And a lot of them were anthropomorphic too, to the point where they looked like they had stepped right out of a cartoon. It was something that made her head hurt. Seeing them walk around like this... She really just wanted to be home at this point. Anything to wash her eyes and get rid of the sight in front of her.

Batgirl was still trying to piece everything together as she watched the world around her. She took note of the particular ways that the Diapercritters were taped up, as well as the way the ground underneath her was taped. It was all as if they were strategically snapped shut to the point where it was impossible for somebody to just fall into them. But with a few tapes undone, they would be able to stuff somebody inside. Not in the same way that you would be stuffed into a pouch, but rather literally and completely stuffed inside. Not that anybody would actually do that.

The trip to the Diapercritter Kingdom's big equally diaper-constructed castle didn't take too long, and getting to the throne room wasn't hard either. Though Batgirl did notice that most of the knights looked like some form of hound, all of them wearing diapers that seemed to be like armor. While not actually being armored. They certainly tried to look like they could protect something, but it wasn't quite as effective as it probably could be.

"I brought them, King, Queen!"

As they were ushered into the throne room, the three heroines were given a first hand look at the rulers of this Kingdom. And the fact that despite one of them being a King, both of them were very distinctly female. Complete with rather generous breasts, both almost as big as their heads. And on top of how big their maternal mammaries were, the rest of their bodies were enormous too, making them truly seem like rulers.

"You've done very well, Hannah." The King, a Tiger Diapercritter, said as she slowly got off her throne. All while bringing attention to the diaper that also clad her waist. Unlike her loyal guide, she didn't wear it to replace a pouch. The regal white and gold was a status symbol, and the crown printed on it replaced the need to wear a proper crown.

"Indeed, indeed. What wonderful heroes. So cute. So tiny." The Queen, a Fox Diapercritter, chimed as she got up from the throne as well, bowing before the heroes that had come to meet her. It was not often that she and her dear King had a visit from those that came from other worlds. Not because Hannah's efforts had been ineffective, but because she just hadn't been able to get to many worlds yet.

Supergirl giggled as she flew right up to the King, bowing a bit herself. "So, what did you need us for? Hannah said that you needed us to model your heroes after, but how do you do that exactly?" She asked another question that was possibly too dangerous...

"Supergirl, that's enough. You've done more than enough to get us this far, you have to be careful." Wonder Woman said as she took flight, flying right over to her and gently grabbing her arm. "King and Queen of Diapercritter Kingdom, I must ask a simple question. Why exactly have we come here? And I don't recommend trying to lie."

Batgirl looked at Diana taking initiative, and yet something was still bothering her. Was this really just a visit to another world, or-

"Why, it's to make adorable Diaperheroes out of you!"

All three heroines' eyes widened as they were rather forcibly grabbed by the oversized animals, and before they had much of a chance to stop them, they were stuffed right into those massive diapers that each of them wore. Supergirl went into the King's diaper, Wonder Woman into the Queen's, and Batgirl went right into Hannah's.

"Such a good job you've done, Hannah! These are high quality Heroes!" The Diapercritter King giggled, gently rubbing her hands over her diaper. "She'll make a wonderful Diaperhero, and she'll be a wonderful assistant in spreading our Kingdom's influence!"

"Ohoho. As will she." The Diapercritter Queen chimed, slowly brushing her big plush tail up against her own diaper. It felt really nice, something that she didn't get to indulge in very often. "And what about yours, Hannah? How is she?"

"I don't think she's going to be as strong as yours, My King and Queen!" Hannah cried out, bouncing right on her diaper to make sure that her Hero had been pushed as far into her as she possibly could. "But she'll be wonderful, once she's been fully converted!"

None of the three heroes could do much in their current situations. How were they supposed to do anything, while they were trapped inside three oversized furry creatures? Well, they hadn't expected being stuffed into their diapers to make them pop right into their bodies, but it did seem like the logical conclusion.

As for being inside them, none of them expected it to be such a tight experience either. It was like they were being compressed by all sorts of plush pamper fabric. Being squeezed nice and tight until they couldn't even try to struggle, all while it was like something was being pulled out of them. Something that was... supposed to be important...?

All three of them had their minds slowly drift, all while the three Diapercritters had a set of symbols appear on their diapers. The Supergirl emblem on the King's diaper, the Wonder Woman emblem on the Queen's diaper, and the Batgirl emblem on Hannah's. All of them brimming with power, while their bodies vibrated and twitched and moved ever slightly the longer the three spent inside of those wonderful diapers of theirs.

Right until the power vanished from the emblems, and they turned nice and gold like the other trimmings on their diapers. Allowing each of the three culprits to reach into their diapers, treating them like a set of pouches, before pulling the trio out and plopping them right down on the wonderfully soft floor...

Being stuck inside of those three Diapercritters and then being pulled out was enough to leave them disoriented, but there was something else that felt really weird. It was like... It was like they were soft all over. And it also felt like they were really empty on the inside. What was going on, exactly..?

"Such cute Diaperheroes you've become! Oh, you're just adorable!"

The King and Queen spoke in unison, and that brought the attention onto the heroes' bodies. They were... They were made of diapers! And not just that, their clothes were very clearly also made of the same material! It was like they were made of diapers, wearing diapers, while also wearing clothes that were made of diapers!

All three of the heroes wanted to try and fight back against this. But all that happened as they tried to struggle was the back of their diaper moving ever slightly. And as they looked at one another, the reason why became rather clear. Their consciousness... It was in their diapers, instead of in their bodies! And the only way they could tell was because their faces were printed right there!

But that wouldn't last. All three of the Diapercritters that had helped them turn into humanoid diapers picked them up and gave them a big ol' kiss that let a new kind of sensation through them. A big, plushed and diapered love, that... that...!

All three Diaperheroes started to vibrate for a moment as they let out cute little baby giggles, all while the back and the front of their diapers started to fill. So much mush being pushed into the back of their diapers, making the displays of consciousness stretch out further and further, while the colors drained and made them look more like a simple outline. All while their expressions turned nice and over encumbered by their pleasure. It probably didn't help that the front of their diapers were growing nice and wet and soaked thanks to all the pee pouring into the front.

And just like that, the former Heroes were made into little more than mush in their diapers. All while the new Diaperheroes, born into adorable infancy thanks to their Mommies, giggled and drooled as they looked up at them with goofy smiles.

When they finally grew up and became proper Diapercritter Heroes like they were meant to be, then they could go help Momma Hannah make more Diaperheroes..!

So much fun awaited them, even if their little baby brains couldn't even process much beyond Poopy and Mommy...
