[Mental Regression, ABDL, Memory Alteration, Diaper Use, Soiling]

Trinity City. A city where Civilians, Heroes and Villains live alongside one another and have to deal with one of the three trying to influence the other. While the Civilians didn't have much influence due to their natural lack of power, the other two were always trying to get one over the other. Whether it was the powerful individuals that served Titan Industries that tried to gamble the system in its entirety, or the independent villains that just wanted a slice of the pie in their own way.

Today was no different, as another Heroine and Villainess were currently clashing in the skies above. One extra advanced Heroine, and a Villainess who wanted to take things at her very own pace.

"Can't you just leave me alone for five minutes, Athena?!" The villainess, Chronoa, was dressed in a bodysuit that was decorated with clocks. Every little inch of her was covered in clocks, and she could spin them accordingly to make sure that she had control over her own time. Which she used to make sure that she would avoid the attacks that were heading straight for her.

Her pursuer, and the mechanical Heroine that served as one of the highest ranked in the city thanks to the tech that adorned her body, was not interested in giving her a chance to breathe. "Stand down, Chronoa. You will be retained, and you will be charged appropriately for your crimes. With all of your manipulation, you've racked up enough crimes that we can shut you away from life without a chance of you rewinding to the start of your sentence or skipping all the way to the end!"

Chronoa grit her teeth as she blipped right out of existence, only to appear on a nearby roof that she had been standing on a few minutes before. Her powers were vast, yes, but if she didn't have the chance to concentrate then she couldn't use them properly. And considering the amount of missiles that were heading her way at every moment, as well as the laser blasts from Athena's armor smashing into the buildings that she used as support... Damnit, she barely had a moment to really get a hit in.

"Target locked on. Ready to fire at your command, Athena." The onboard AI for the armor, AEGIS, was always helpful whenever Athena had to catch criminals and Villains that were being particularly troublesome. And its abilities were incredible. Even somebody like Chronoa, who was able to pop out of spacetime for a few seconds to adjust herself on the temporal axis, wouldn't be able to escape for long. Not when AEGIS was able to get a lock on her.

Athena nodded as she hovered in place, her armaments adjusting and locking onto Chronoa with malicious intent. All while they charged for a few moments. This next shot would finish it. It would pierce through and strike her, even if she tried to traverse through time. She was sure of it. Every second it charged would equal a couple of weeks worth of temporal energy. And Chronoa's defeat wouldn't do anything to the timeline due to how she interacted with it...

"What's the matter..?" Chronoa gasped and panted as she brushed a hand through her long black mane that ended in a tip that looked like a clock's hand. "You're taking a long time to charge, Athena! Are you taking it easy on me, or are you preparing something you think might just finish me off f-" She paused just as she clued herself in on what was about to happen. And the dawning realization swept across her, trembling more and more. No, she didn't want to go out that way...

Athena didn't answer. She just let the cannon that had grown from her mechanical chest stick out a bit more. All while the energy kept charging at that very tip. No nonsense. No mercy. Not for somebody that served as such a threat.

Chronoa grit her teeth as she quickly started to gather her own power. Fine, if she was going to try and wipe her out with a blast like that, then she had only one option left. She didn't want to resort to this, but if she wanted to finish her off for good, then she'd finish her off in turn. When she was done, nobody would look at Athena with respect ever again. Nobody would treat her as anything less than a complete moron!

"Chrono Chaser! Fire!" Athena shouted as an arrow-shaped beam poured forth from her chest, the beam intended to hit the target no matter what. So much so that it phased through time itself, with no chance for the target to avoid it. Even if she traveled to a physically different point in time, she would be chased. Even if she leapt away by a year, it would keep chasing her. It was guaranteed to hit her, no matter what!

The time-controlling Villainess let out a shout as every clock on her body started to spin, only to disappear right then and there, leaving nothing behind. And while the beam certainly tried to follow her, it eventually started to just fizzle out as there was no target in sight.

Athena blinked a couple of times as her systems started to wind down, steam blowing out of every possible vent, all while she landed on one of the buildings. "AEGIS, what happened?" She asked, blinking a few more times. She wasn't seeing things, right? Her last attack had genuinely been completely unable to meet its mark, right..?

"It seems as if she has jumped beyond what we were trying to hit. Current temporal data reached beyond my scope. Apologies, Athena." The on-board AI said, the voice sounding as stoic as ever as it apologized for something that was honestly crucial considering the crimes that the time-controlling Villainess had been able to carry out.

Athena just shook her head and sighed. "It's alright, AEGIS. We managed to make her run away at least. If she shows up again, we'll just have to charge the Chrono Chaser for longer to make sure she can't escape." She said, keeping positive despite it all. "Now, let's keep up the good work!" The Heroine declared, taking off into the skies once more.

Little did she know that Chronoa's latest leap was targeted specifically on her, nor would she realize it until it was far too late.

As the day came to an end, Athena was more tired than ever. Fighting all these criminals was tough, even with armor as advanced as hers. Sure, she had a bunch of different weapons that she could use, but that didn't mean that they were all effective in the same situation. Something that had cropped up during the day, as she became more and more reliant on the missiles that she didn't need to worry about aiming.

"Are you feeling alright, Athena?" AEGIS asked, the tone a little more... maternal than it had ever been. In fact, it wasn't the first time that it had asked about her current state. It had begun to ask a lot more throughout the day, especially after every encounter.

Athena softly nodded. "I don't... think there's anything wrong with me?" She said, smiling softly. "Would you mind letting me out of the armor, AEGIS? I think I need a bit of fresh air." She asked. Honestly, maybe she just had a headache from all this fighting. Maybe that was why she had started to rely on attacks that weren't really super effective. Maybe that was why she didn't really bother thinking so much.

For a slight moment, it was like she could hear a clock ticking by. And AEGIS refused to listen to her command. "...AEGIS? I-I want out of the armor." She asked again, hoping that it just hadn't registered the command for some reason.

"I cannot do that, Athena." AEGIS replied. "According to the agreements we made, you have to be in armor for a certain duration of time. We still have another few hours before that time limit is hit. You don't need to worry, I will take care of everything." Not only did the voice sound maternal now, but it took on a slightly more stern tone as well as a significantly more feminine tone. It was more appropriate to call it a her than an it now.

Athena blushed. "I... How long did I set it for..?" It was like something was wrong. She didn't remember setting a time limit. Much less programming AEGIS to be this much like a Mother. And yet having her talk to her like this, assuring her that everything was going to be alright...

"Another thing, Athena." AEGIS spoke up again, as the insides of the armor grew nice and soft and comfortable. "AEGIS is a designation that you wished to delete from my databanks. You said that Mommy was better for me, because I always kept you nice and safe like one." She explained, the words sounding right yet at the same time clashing with Athena's own memories...

"A-Ah. Okay, Mommy..." Athena didn't really understand. But it felt right to listen to Mommy. "Do we go beat up more baddies then..?" She barely even noticed that her own vocabulary was degrading as she spoke. It was getting much simpler. Much less complex. Almost like a child's.

"Mmhm. We beat up all the baddies that would make you sad. And then we'll go out for ice cream. How does that sound, Athena?" Mommy knew exactly what to say to make Athena feel better. This was what she was programmed for. She was programmed to make sure that her wearer and her 'pilot' was as comfortable as possible. And that meant to baby her a bit to make sure that she was up to speed with everything.

Athena giggled as she heard that. Ice cream always made her feel a lot better. Then she didn't have to worry about anything. She could just eat and eat and everything would be okay. "Okay, Mommy! Let's beat up baddies!" She cried out, giggling lots as she grew nice and excited. She always loved seeing Mommy beat up all the baddies. But why did it feel like she had been the one beating baddies before..?

Another tick echoed around Athena. And then she felt a little crinkle between her thighs. Strange, what was that sound? It wasn't something she had heard before, and yet it felt really familiar. It felt so familiar that it made her eyes dim a little.

"Athena, dear? Have you gone potty?"

Hearing Mommy caused her eyes to widen and regain their color. And then the smell of what she had just done hit her nose. N-No, there was no way that she had wet herself. She was a big girl. She was a big smart girl in a big smart armor that she had helped make! She helped make it, so she definitely wasn't pissing her pamper!

B-But telling Mommy that she hadn't gone potty would mean that she was lying. And then Mommy would punish her. So it was best to be truthful. Because then Mommy wouldn't punish her. She'd tell her that everything was okay...

"M-Mmhm. Athena went potty in her pampy..." Athena muttered. She really wanted to suck on her finger to make it all okay. Whenever she got like this, whenever things got really tough and she didn't know how to deal with it, she always resorted to suckling on something. Especially when she had made her diaper all heavy thanks to her very weak bladder, or god forbid, went number 2 in it and really filled it...

A soft sigh echoed from the AI that helped control most of the armor. "It's okay. We'll get you changed once we're done dealing with everyone. But until then, is there something else you'd like to do, Athena? Or do you think you can hold it until you get changed?"

Athena listened carefully to what Mommy was saying. And yet it didn't really register. She didn't understand why it didn't, she knew what the words she said meant. But it was like it went right in through one ear and right out the other. So much so that it was making her really nervous. She really wanted her thumb in her mouth. And if she didn't have her thumb, then.

"Oh, poor thing. You're all worked up and nervous. Don't worry, Athena. Mommy knows how to make it all right." Mommy said, and before Athena got to stew in her own worries and get so worked up that she couldn't speak or respond, a pacifier found its way into the poor girl's mouth. The soft rubber quickly getting suckled on, fixing any problem that her little baby would have thanks to her oral fixation not being satisfied.

With that paci in her mouth, Athena's heart slowly started to beat at its normal rate. And she giggled softly, not at all worried about what was happening to her at this point. It felt so nice to just suckle on her paci. It felt so nice that she kept on suckling and suckling, forgetting everything about anything else while she experienced this absolute bliss...

So much so that she didn't even care about the fact that her poor butt was starting to let out a lot of gross sounds. Nor the fact that her diapy, which was so thick that it was a wonder it even fit inside the armor, was quickly forced to sag even further down. Even if she could move and think like an adult, she wouldn't be able to operate the armor with such a poopy and stinky diaper stuffed down into the deeper crevices of the armor.

Mommy just giggled as she could feel her little baby girl filling up the insides of her armor. Taking care of her and making sure that all of her needs were dealt with was one of her most important tasks. The woman that had helped program her to make sure that Athena was always safe and never needed to worry about anything else... She had made sure that this was her primary routine. Not fighting against baddies. Not protecting the innocent. Just protecting little Athena.

And as Athena continued to softly suckle on her pacifier, the armor took off into the skies. Mommy had to carry out her duties, so she could dote on Athena more and more...

---

Athena yawned. It felt like she had been napping for a buuuunch of time. But it was nice and comfy inside Mommy, so it was okay. And yet... It wasn't actually that soft. Which meant that she wasn't inside Mommy. Which meant...

"Rise and shine, Athena. You little stinky idiot baby!"

Athena's eyes shot open as she heard that mean voice, looking straight up at a woman that looked really familiar. As well as her armor that had Mommy on board, which now looked a lot more sensual and properly motherly instead of an armor that was meant to protect people from baddies.

"Y-You... C-Chronoa!" Even though her mind had fallen far, she could definitely recognize the clock-clad woman. She was bad news. Really bad news. Especially if she was outside of Mommy. "Mommy! Chronoa bad!" She cried out, hoping to at least make Mommy hurt the bad woman!

"Baby Athena." Mommy's soft voice made the diapered girl, who had been changed into a clean nappy while she was sleeping, shiver and shrink as all of the confidence left her body. "What did we talk about? You don't just call people bad for no reason. Everyone deserves a chance. Especially Mommy Chronoa. You've met her before, remember?"

The diapered girl whimpered. Not just because Mommy was scolding her, but because she got a good look at her current outfit. She was clad in little more than a cute onesie that was decorated in adorable little ducklings that made her look like an overgrown infant, and having her formerly long and beautiful blonde locks tied into a pair of childish pigtails didn't really help matters there either. Even though she had a very generous bust, her boobies didn't seem impressive or mature when they pushed out against her onesie. And to emphasize her childish state, her hands and feet were equipped with a set of mittens and booties.

Athena didn't like wearing it. Well, it was fit for a baby like her. But seeing Chronoa made some parts of her mind fix itself. It's just that she couldn't go against Mommy's words, so she was reduced to whimpering, hoping that she'd find a way to make Mommy help her.

"It's okay, AEGIS." Chronoa said, grinning a little as she wrapped her arms around the sensually-shaped living armor. "Since you've been taking so good care of her, she's probably forgotten all about what happened before you were permanently bonded. But it's okay. I saw it all. I'll tell you what happened."

As Athena felt her heart sink, thanks to Chronoa practically making out with the robotic armor that she considered her maternal figure, that heart only sank further and further. Especially as she heard Chronoa spell it all out.

"When Athena was a very little girl, with such a smart head on her shoulders, she always wanted a friend. But she didn't know how to make one. She could make a lot of robots, but she could never make a friend. That's when I came to visit her, and helped her make one. All it took was a little wire, and Athena had a friend that could take care of her at all times. A friend that would protect her no matter what. A Mommy. That's what AEGIS is." Chronoa explained, grinning a little. "You know what that means, don't you, Idiot Baby?"

Athena could just barely understand what it meant. Somehow, Chronoa had gone into the past to do bad things to her. And all of her smarts and stuff were used to make Mommy. She could just barely remember how the original version of the events had gone. How she had copied her mind, instead of it being drained to make Mommy.

"M-Mommy... C-Chronoa bad! Bad bad!" Even though she was barely able to properly say anything, even though she had a big diaper around her waist that made her legs unable to ever close, even though she looked like an adult trying to be an infant... She really, really didn't want to spend time around Chronoa. Especially now that she realized that she had been behind all of this!

AEGIS shook her head as she carefully removed Chronoa's hands from her body. "I don't like your tone, little lady." Mommy's voice turned extra stern as she glared down at Athena. "Mommy Chronoa helped you make me. And this is what you say? You say that she's a bad woman? Then does that make me bad, since she helped you make me?" She asked, all while her intimidating metallic figure hovered over her little baby girl.

"B-But... But Mommy..!" Athena tried to cry out, only for a pacifier to slip into her mouth. Courtesy of the Villainess that had helped turn back the clock so badly on her mind. Her protests were made nice and quiet, and replaced with little more than the sound of constant and eager suckling. Because even though she wanted to see Chronoa gone, she really couldn't fight against her baby instincts.

"She really is a handful, isn't she?" Chronoa said, giggling a little as she sat down right besides that padded girl that had been such a thorn in her side. "But it makes her so cute. Whenever she thinks she's an adult, she starts getting all huffy. And then it won't be long before something goes byebye inside that head. Never to return." She chimed, all while gently rubbing Athena's belly in such a foreboding fashion.

Athena squirmed a bit, but then Mommy sat down beside her, and gently patted her on the head and hugged her. "Indeed. The process that allowed my ego to form ultimately deprived her of her ability to develop. So every time she starts thinking she's an adult, she ends up using more of her brain than she should have access to. And once she loses control and has to go number 2, she can't control that part any more. It's a wonder she's still able to talk..."

The thoroughly stupefied girl wanted to try and stop them from bullying her and talking down to her. But she didn't know how. Even if she tried to use her brain, it was like she was slipping. Like there was a big slippery slope that she was trying to climb up, representing her lingering adulthood. And now that she was slipping, she couldn't get ahold of it again. She was tumbling, tumbling...

Until her eyes started to dim, and a faint hiss started to echo between her thighs. Slowly but surely, the front of her diaper started to bulge outward as it soaked up more and more of her pee. All while she looked super satisfied. All while a wave of complete and utter bliss started to pour over her. What was she thinking about, exactly..?

"Ooo, she's gone potty already. Guess she won't be able to speak much longer!" Chronoa giggled, all while reaching down to rub that incredibly wet and sticky spot on the front of the babified Heroine's diaper. It was nice and hefty. Packed full of all sorts of heavy adult thoughts that she didn't need. Full of things that Athena had kept precious.

AEGIS nodded a little, squishing that diaper as well. "It's okay to let it all out, Baby Athena. You don't need to worry. Your mommies are right here. That's right. We're always here for you. No matter what." She said, gently kissing her on the cheek with those gentle metallic lips. Even if they were cold, they were nice and maternal, and would always be there to keep her company. No matter what. She would protect her at all costs...

Athena listened to both of them. They were her mommies. That's what Mommy said. So it had to be true. And if they said that everything would be okay if she pushed, then everything would be okay. She just had to push and then everything would be okay.

The babified Heroine trembled a little as she pushed. She even started to lean up against the Mommy with all the clocks as she trembled more and more. Before she let out a deep and satisfied sigh, and a big stinky mess was pushed right out of her pampers. It was extra stinky and it was extra heavy...

Not only was it extra stinky and extra heavy, but it kept going until the flap on the back of her onesie popped open, revealing that browned pamper to the world. All while she drooled all around her paci, the look in her eyes revealing just how impossible it was for her to regain any little bit of her adult sensibilities. There was no longer any bit of her adulthood left inside her head. She'd have to depend upon her Mommies. Forever...

"She's so cute when she goes number 2 like that." Chronoa giggled. Ah, seeing her fall like that, after how she had cornered her before and nearly made her completely lose... It was so satisfying. "Do you mind? It's not like we can change her right here, not after she's made such a mess." She asked her fellow Mommy, giggling and grinning a bit.

AEGIS nodded as her body opened up and allowed her fellow Mommy to stuff the blissful baby inside, the space properly tuned to make sure that she would be comfortable no matter how much she had pooped herself. "I'll make sure to take her home. And then after that, I'll be ready for whatever you need, Chronoa."

Chronoa grinned, all while reaching forward to kiss her fellow Mommy right on that metallic cheek. Not only had she managed to turn her enemy into an infant that couldn't do anything to stop her... But she had turned her annoying armor into both her ally and her lover.

Perhaps she should make another few babies out of the city's heroes... And steal away their companions to be hers as well, just to rub it all the way in.
