In 2025, a new type of game was invited. At an arcade, you would be transformed into a hero or a villain and fight another person. The testing for these games were so long since the creators wanted to change the transformed’s minds to think like the characters until the game was over. That didn’t matter now since Maria and Julie were finally able to take a shot at this game.

“Heads or tails?” The operator asked Maria

“Heads.” Maria responded, the operator flipped the coin to find it landed on tails.

Julie pumped her fist and said “I want to be the villain.”

“Alright, you go in the purple door. Other girl, go in the blue door.” The operator said. Both girls complied and entered their doors.

Inside, they couldn’t see each other but they both saw the wheel in the center with a random games in it. “Players. Are you ready?” A robotic voice asked. Both girls nodded and the wheel started spinning. It slowed to a halt as the words  “Super Mario Bros” appeared above them. On one side, Julie was excited to become a giant turtle dragon while Maria wasn’t so excited to become a fat Italian man.

“Changes initialized.” The robotic voice said, causing a tingle to spread through the girls bodies. This also made Julie’s clothes disappear since she wouldn’t need them.

Julie’s blue dyed hair started turning a reddish orange color. Her hair started falling out until she was left with a mohawk. She reached up and felt her eyebrows get bigger and bushier. Up on her forehead, Julie reached up and felt her new horns grow out. Julie looked at her arms as yellow scales started growing on her chocolatey skin. Julie looked in the reflected part of the area she was in and saw her whole body be consumed by the scales. It even covered her woman hood, making her completely genderless.

A small stretching feeling in their tailbone told Julie that their tail had just grown in. They moved it around to see the small spiked tail. Julie then felt a throbbing in their hands. They looked at them to see their pinky and ring finger merging.  The fingers got thicker as the nails turned into claws. Julie’s arms started bulging with muscles. The changes continued into their body as Julie’s curves were quickly filled with fat, bulking up their body for Bowser. Their body started becoming rounder and rounder to the point where their legs couldn’t hold them up anymore. Thankfully, the changes moved south filling their legs with the same fat, making them bigger and strong enough to hold their new body. Julie looked down at their toes to see them merging into three toes with claws.

The final changes started setting in as Julie’s mouth started puffing up and merging with their nose. Their teeth started sharping into fangs as metal bands with spikes appeared on their wrists and shoulders. For their final change, Julie felt her back arch as spikes grew out of it. The scales turned green as it became curved, turning into their shell. Julie let out a deafening roar  when their changes completed… or so she thought. Memories flooded their head quickly replacing Julie with Bowser who was ready to get rid of Mario’s lives.

Maria was nervous as her blonde hair shrank back into her head, turning brown. She looked into the reflecting wall to watch herself shrink. It looked like she was going to start at the small version of Mario. She got closer to see her green eyes turn blue, and her nose start inflating to a bulb. Maria felt her upper lips tingle as a thick mustache grew in. Her chin grew a little bit as her shoulders became broader. Muscles filled her arms as gloves covered her growing hands. Maria’s blue shirt became red as her jeans reached over her shoulders and became overalls. Her hips shrank back, losing her hourglass figure. Maria’s thighs and ass shrank into her body, becoming toned as hair covered them along with her arms.

The fat in Maria’s breasts shrank into her body and grew in her belly, giving her a bit of a gut. For the final change, Maria felt a heat grow over her vagina. Her ovaries started moving to the outside of her body as her clit started shaking. Her womb disappeared as her ovaries pushed out onto her outer body. The ovaries swelled and became testicles, her clit growing out and becoming a decently sized cock. Finally, her vagina sealed up, making Maria into Mario. Memories flooded into her, making him think about rescuing the princess and going to fight Bowser. A horn sounded and the two began fighting.
