Eri Versus Android 18 (Patreon)

"We have an interesting match for the 25th World Martial Arts Tournament!" The announcer declared as he held his microphone up in a dramatic fashion. "A little girl known only as "Eri" has decimated all of her competition in the Kid's Division and, since this year's tournament has been a bit lackluster, the higher ups have decided to give the young child a shot at 18, the current World Champion!"


This sudden change in the lineup was well received by the audience who started to go wild, cheering and clapping for both 18 and the mysterious child who was an unknown fighter.


Eri looked out of place as she stood on the tiled tournament ground. Intimidating was not a word anyone would associate with the young girl as she looked out at the crowd. She wore a simple white dress shirt with a frilled collar that was underneath her blue pinafore dress that featured two large buttons on opposite sides of her chest. Although she looked shy, her feet were firmly planted on the ground, clad in a large set of tan boots that stood out thanks to her black tights. For some reason the child held a red small messenger bag that was slung over her right shoulder a red strap sitting ending in a little floral decoration.


On the other side of the arena stood Android 18. The blond housewife didn't exactly look like a seasoned fighter but she had already proven herself on these hallowed grounds twice before. She casually brushed her blond hair behind her left ear, causing her hoop earring to jingle slightly while her blue eyes stared at her "opponent" in disbelief. 'That kid looks like she's six or seven years old!'


"Shouldn't a nice little girl like you be playing with your dolls?"


Eri frowned slightly which caused 18 to grin. 'Why is this lady being so rude? She looks like she should be hanging out at the mall or something.'


Eri wasn't wrong. Unlike most contestants who had participated in the tournament, 18 looked like she was enjoying a casual friday. Her black shirt, with black and white strips on the sleeves looked odd considering that even the children who Eri had beaten wore karate attire or training outfits, not the blue jeans that 18 rocked.


"Aww, is the baby too little to talk?" 18 teased as she started walking up to the little girl.


Even though she felt like she was on the verge of crying, Eri refused to let her emotions overwhelm her. The poor girl had already proven herself, but 18 either didn't care or was severely underestimating the girl's power.


The blond stared down at the little girl and noticed that she had tears threatening to spill from her eyes.


Look at you! You're about to cry like a little baby!" 18 taunted. "You poor thing. You should've never left the nursery to try and be a big girl."


Eri could no longer hold back as her tears flowed freely. She did her best to try and stifle her sobs, bringing her hands up to her face in an attempt to hide her tears from the crowd, but it was a futile effort. Still, unlike 18, the crowd wasn't going to insult a mere child, a child who had won her Division, just because of a few tears.


Meanwhile, as Eri cried, 18 looked satisfied and turned away from the girl to address the crowd.


"Looks like this little girl is in no shape to-"


*SLAP*


A loud smack of flesh on the back of 18's blue jean clad ass rang out, simultaneously startling the blond bombshell and interrupting her impromptu speech. Eri kept delivering the firm swats to the blond's backside, her anger consuming her while she repeatedly swung her arm at 18’s ass. As the spanking continued, the sounds of the backside assault slowly started to sound more like someone slapping a plastic garbage bag than the traditional sound of a typical spanking.


Needless to say, this unexpected development had 18 on the verge of unleashing all of her power, that's how pissed off she was, but the crowd's sudden laughter surprised her almost as much as the spanking. A lone spectator shouted out the last thing that 18 wanted to hear.


"Nice Pampers, baby!"


That single insult instantly confirmed her suspicions: the weird bulk around her crotch that vibrated with each continued spank, the odd slapping sounds that came from her backside along with the cool breeze which occasionally graced her thighs. The blond slowly looked down, not wanting to see it, but suddenly finds herself staring at the last thing she had ever imagined herself wearing: An oversized baby diaper.


"You little brat!" 18 screamed out in pure rage. "I'm going to destroy you!"


18 spun around and grabbed Eri by her arms, hoisting the tiny girl above her head. Eri was mere inches above 18's head and knew that she had to act fast, least she get smashed into the concrete tiles by her opponent. Before 18 could hurl the six year old,  Eri reached out and placed her finger directly onto 18's forehead, activating her Quirk.


The blond fighter was overcome by a wave of dizziness as Eri held her finger to her head. The blond  could feel her mind reverting back to a more infantile state as everything lost its meaning and her coordination started to falter.  18 tried to fight the degradation of her brain cells as her mind reset itself, but she lacked the tools to combat this kind of technique. As the minutes ticked by, she felt her mind growing more slow and dumber.


"Pwease, stop dis!"


"I didant men ta beh a meanie!"


Her attempts at diplomacy fail to sway her opponent who held her finger in place as 18's arm's started to waver. The powerful fighter could feel her hold on reality slipping as the memories of her life fade away into nothingness.


"Yous a poopie heads!"


"Ahhh, agoo gagaa!"


Eri felt her stupefied opponent’s arms give way, the once tight grip fading away until the young girl was released from 18’s grasp.  The young girl took the opportunity to jump away from 18 while the blond stared blankly off into space. Eri lands gracefully on her boots, but the newly diapered 18 is not so lucky as everyone, including Eri, watched the infantized 18 fall onto her padded backside with a loud crinkle.


The pint sized fighter made her way over to where 18 sat, each step sounding like the pounding of a drum to the diminished 18 who no longer could comprehend what was going on around her. Eri gazed down at the confused baby woman she was barely standing over. The white haired child could see it in the blond's eyes: fear, confusion and sadness. This dramatic change of roles, or maybe it was the fact that 18 wanted her mommy, caused the diapered World Champion to start bawling like a baby.


However, Eri didn't care. She smiled a big grin as she reached down and touched the fabric of 18's black shirt causing the garment to instantly change shape while transforming into a nice baby shirt that was a nice shade of pink. The new shirt clung tightly around the blond's big breasts and barely reached 18's belly button above her enormous diaper.


"That's better, but something is missing."


Eri stared at the drooling adult baby knealing beneath her and has an epiphany. 'She needs some pigtails to complete the look!' Eri is careful to avoid directly touching 18's head again, not wanting to turn what’s left of her brain to mush as she starts putting the adult baby's hair into pig tails.


"There. Much better. Maybe if you're a good girl, someone will change your diaper."


The remark caused an overwhelmingly loud response from the crowd as everyone present started laughing which caused the diapered fighter to start crying. Eri smirks down at the startled 18 who’s cries quickly turned into wailing.


Eri was done playing with the baby.


The little girl walks away from 18, feeling triumphant and happy to leave the now mentally babyfied 18 to be laughed at by the audience. She earned her prize money, but wished that she had been given a worthy foe to fight instead of such an overgrown brat.
