Batman x Arc Reactor [DC]

Harley leaned against the locked door, breathing heavily and sweating after her unsuccessful escape attempt. She thought about the limited food and water in the small kitchen and knew she had a tough four days ahead. She wiped her forehead and stood up, looking at the challenging training program on the large screen.

The schedule was unforgiving: intense interval training, strength exercises, combat practice, and endurance workouts, all carefully arranged to allow no time for rest. Harley took a deep breath and whispered to herself, "Alright, Quinn. You got this. Ain't no training regimen that can break Harley Quinn."

The first task was a series of burpees. Harley's body quickly resisted, feeling the ache from her earlier argument with Diana. She groaned but continued, resolute to show she could manage any task given. As she moved through the exercises, Harley found herself pushing past her limits, fueled by determination and stubbornness.

"Take that, Di Di," she muttered, clenching her teeth as she delivered a strong kick that made the bag swing.

After the first day, Harley was exhausted but still managed to complete her tasks. She collapsed on the floor, her muscles sore and her clothes soaked with sweat. She barely had the energy to crawl to the kitchen and grab a bottle of water, chugging it down before falling onto the small bed in the corner of the room, her muscles were shaking, and her mind was filled with tired thoughts. She looked up at the ceiling, wondering how she would make it through the next three days.

Harley shut her eyes and slipped into a restless sleep.

The following morning, the loud alarm woke Harley up. She sighed, feeling pain in every muscle as she forced herself to get out of bed. The screen turned on, showing the day's exercise plan. It was even harder than the day before.

"Wonderful. Just wonderful," Harley grumbled, rubbing her aching neck. "Who knew Wonder Woman could be such a sadist?"

The second day began with a brutal cardio circuit: sprints, climbing ropes, and jump squats. Harley pushed through, gritting her teeth against the burning in her legs. She forced herself to think of anything other than the pain – like how she ended up in this situation in the first place.

"I shouldn't have pissed off Wonder Woman. Or taken her armor. Or her lingerie. Fuck!" Harley cursed as she completed another set of jumping jacks.

As she moved on to the strength training portion, lifting weights that felt impossibly heavy, her mind wandered to Bruce. He gave her a second chance to turn her life around, yet she just had to do that stupid thing.

After an exhausting afternoon of strength training, Harley could barely stand. Her stomach growled with hunger, and her throat was parched. She stumbled over to the kitchen and ate a protein bar, barely tasting it as she scarfed it down. Her eyes were heavy with fatigue, but Harley knew there was still more training to do.

By evening, Harley was drenched in sweat, her clothes clinging to her body. The training for the day was over, but she couldn't bring herself to move. She lay on the floor, staring at the ceiling and contemplating her life choices. "Two down. Two to go," she whispered, closing her eyes. Her body ached, but a small part of her felt a strange sense of accomplishment. She had made it this far but was too exhausted to continue.

Day three was no easier. The alarm woke Harley from a fitful sleep, and she groaned as she rolled out of bed. Her muscles protested with every movement, but she forced herself to stand up. The screen displayed another grueling regimen, and Harley sighed.

"Alright, Quinn. Let's do this," she muttered, dragging herself to the kitchen. Her eyes fell on the self and there was very little food left. "Ah! Crap! I shouldn't have eaten all that yesterday!"

Harley took a protein bar and ate it quickly, knowing she would need all the energy she could get for the day's exercises. She stared at the screen, reading the daunting tasks.

The focus of today's training was mainly on stamina. Harley had to do long runs around the edges of the training room, climb stairs, and do many rounds of planks and wall sits. These activities really challenged her both mentally and physically. Despite her heavy breathing and the effort it took, she kept going, making her body continue to move.

By the middle of the day, Harley was almost at her limit. Her legs felt very heavy, and she was so tired that her vision was getting blurry. She almost fell, but managed to steady herself against a nearby wall. She closed her eyes and tried hard not to quit. But couldn't help herself from screaming and crying. Dragging her feet to the door, she began to bang on it loudly and demanded Diana to let her out. After a while, Harley slid down to sit on the floor, resting her head against the cold metal door. She sobbed quietly, feeling defeated by the training.

"I'm sorry. I'll never wear your clothes, just get me out of this hell," Harley cried weakly, tears streaming down her cheeks.

She didn't know when she fell asleep. Never in her life did she experience such physical exhaustion. When Harley opened her eyes, she found herself lying on the floor beside the door. The screen was showing the leftover task. Harley wiped away her dried tears and struggled to stand up.

"Come on, Harley. You can do this," she whispered to herself. "Just think of it as payback for all the times you messed with Di's stuff."

She forced herself to continue, moving on to the next set of exercises. Each movement felt like a Herculean effort, but she pushed through, determined to prove she was tougher than any training regimen Diana could throw at her. By the time the evening rolled around, Harley was barely able to stand. She stumbled to the cot, collapsing onto it and closing her eyes. The relentless training had taken its toll, and she drifted into a deep, dreamless sleep.

The fourth day dawned, and Harley awoke with a sense of dread. She knew this was the last day of Diana's regimen, but it didn't make it any easier. Her body felt like it had been put through a meat grinder, and she struggled to get out of bed. Her eyes were bloodshot, and her muscles screamed in protest with every movement.

Her expression was grim as she stood in front of the screen, seeing the list of tasks for the day. She wasn't hungry today and there were only two protein bars left and a bottle of water. Harley decided to skip breakfast and started with the first exercise on the screen.

The day progressed, and Harley pushed herself to complete the tasks. The training was even more challenging than before, but she refused to give up. Her muscles screamed in protest, and she felt like she was running on fumes. But the girl kept going, fueled by sheer willpower, knowing that today was the last day.

By the time the last exercise was done, Harley was on the verge of collapse. She dropped to the floor, panting heavily, and closed her eyes. The training regimen was finally over.

"Hehehe... Hahaha..." She laughed weakly, feeling victorious despite the pain. Harley had survived Diana's training and proved that she was tough enough to be part of the Justice League. "Now, I'm gonna go on a vacation..." She fell asleep.

Later that night, she woke up to eat the last protein bar and water. Harley was famished and devoured the small meal. Afterward, she took a quick shower to wash away the sweat and grime from the past four days. She then collapsed onto the cot, completely spent and ready to sleep for a week.

..

Diana returned to the training room at the end of the fourth day, unlocking the door and stepping inside. She found Harley lying on the floor, completely spent. Diana knelt beside her, a small smile playing on her lips.

"Harley, you did it," Diana said softly, her tone filled with a mix of admiration and amusement. She expected Harley to give up and try to escape from the room but was surprised to see the result.

Harley opened one eye, looking up at Diana. "You monster," she croaked, her voice hoarse from exhaustion. "How can you do this to me? I swear, I'll take all your underwear and hang them in the Batcave."

Diana gave her a sly smirk.

"Sorry, I was just joking, Di," Harley apologized in a weak voice. "You know I could never do that to you after you nearly killed me in that training room."

Diana shook her head, her smile widening. She helped Harley to stand up and escorted her out of the training room. "Let's go. I got something for you." She took her to the dining area and helped her sit on the chair. Then Diana walked over to her locker and pulled out a big bag. She took it to Harley and placed it on the table before her. "Open it."

"What's this?" Harley began to unzip the bag. "If this is a bribe to keep my mouth shut about your torture methods, it's..." She stopped, staring wide-eyed at the contents of the bag.

Inside was brand new armor from Themyscira.

"Oh my God!" Harley squealed with joy, her exhaustion forgotten. "For me?!" She took out the sword and shield, admiring the intricate design and craftsmanship. "These are beautiful! Oh my God, oh my God, oh my God!"

Harley jumped up from the chair and hugged Diana tightly, laughing and thanking her over and over again.

"I love you so much..."

"Yeah, yeah... That's enough hugging," Diana muttered, her cheeks flushed. She gently pushed Harley away. "You better rest up, because you got a new mission. You'll be leaving in two days. So, no more funny business, okay?"

Harley nodded eagerly, her eyes still filled with excitement.

"Good. Now, go clean up and rest. I'll send food to your room," Diana patted Harley on the shoulder before turning to leave.

Harley swang the sword in the air, "Now, I'm freakin' Wonder Harley Quinn!" She made a serious expression. "No. Wonder Quinn. Yep, that sounds perfect!" She grinned widely, unable to contain her happiness.
