BRUCE WAYNE

ARC-1: The Perfect Arc Reactor

As the night covered Gotham City in darkness, a feeling of unease filled the air. Secrets whispered in the alleys, while towering skyscrapers stood as ancient guardians over the city. It was a place that embraced the darkness, where heroes and villains danced an endless dance.

In one of the wealthy suburbs, inside Wayne Manor, a quiet stillness was interrupted by the cry of a newborn. The cries echoed through the grand halls, announcing the arrival of a child. But this child was different, this child was Jack Lance, or so he believed.

Jack's eyes opened, his gaze filled with curiosity beyond his years. He lay in a cradle, wrapped in soft blankets, his tiny fingers reaching out as if searching for something he couldn't quite remember.

The room was softly lit, with the moon's pale beams seeping through the curtains, creating ethereal patterns on the nursery walls. Jack felt the weight of the moment, as if he were witnessing his own birth from a stranger's perspective.

'Wayne!' He heard the nurses' voices, faint but unmistakable. He was certain he heard the word Wayne.

As he looked around the room, a profound realization washed over him—a merging of memories, a blending of identities. He remembered being Tony Stark, fighting against Ultron and Thanos. But now, he was about to embrace a new identity, possibly one of the Waynes, maybe even Bruce Wayne, the young heir to the Wayne fortune.

"Who am I?" Jack whispered to himself, his voice barely audible. It was a question that echoed deep within his mind. Was he Jack Lance, Tony Stark, or a Wayne? Or perhaps a combination of all three?

His journey was just beginning, and the layers of his existence were as intricate as Gotham's dark past. In this new chapter of his life, one thing was certain: he had to uncover the truth about himself and find his place in the complex tapestry of the multiverse.

[3 years later]

Life at Wayne Manor had settled into a semblance of normality—or as normal as it could be in a mansion filled with ancient secrets. Jack, or rather, the amalgamation of his past identities, had grown in this mysterious world.

As time passed, Jack's personality evolved into a unique blend of traits from his former selves. He retained Tony Stark's clever wit and talent for inventing futuristic gadgets. Yet, he also embraced his identity as Jack Lance, a student of physiology from Earth where Bruce Wayne and Tony Stark were merely famous characters from comic books.

And, of course, there was Bruce Wayne, the true owner of the body Jack now inhabited. He was well aware of Batman and his heroic tales from the comics he had read in his past life. Jack had made up his mind to become the new Batman, but he knew he had to start as soon as possible.

"Oh, well, what the heck, I'm just a three-year-old kid," he thought to himself as he played with the remote-controlled Batmobile that he had put together using spare parts from Alfred's toolkit. "I can't be Batman just yet. I'll think about that later. Right now, I need to prevent my parents' death. I have five years to prepare for it."

"Bruce?" a voice called out, interrupting his thoughts. He looked up to see his parents, Martha and Thomas Wayne, standing in the doorway.

"What are you up to, sweetheart?" Martha asked, her voice gentle and warm.

"Playing with my Batmobile," He replied with his usual serious expression that's too serious for a kid of three years old. 'They are early and look jolly today. Something good must have happened...' He wondered.

Bruce was unlike other children. He possessed strength and intelligence beyond his years. Instead of indulging in typical childhood activities, he spent his days engrossed in books far beyond his age level and preferred watching news and science programs over cartoons. This impressed both Thomas and Martha.

Thomas entered the room and sat on the floor beside him, while Martha stood by the door with a smile on her face.

"You got it working?" He asked, peering over to get a closer look at the toy car.

"Yes," he replied, his eyes gleaming with excitement. "I even made a few improvements!"

Martha watched the scene with a smile, her heart warmed by the sight of her son playing so happily. She felt a sense of pride, knowing that her son was already showing signs of a brilliant mind.

"You know, Bruce, if you keep this up, you might become a great inventor one day," Thomas said, his voice filled with pride. "But remember, there are other things in life besides inventing, and your education is very important too. You'll have to work hard and study very diligently if you want to succeed in life."

"I am a great inventor," Bruce said pointing at the Batmobile. "I invented this! How many three-year-old kids can do that?"

Thomas laughed and ruffled his son's hair affectionately, "Yes, you are a great inventor, Bruce, but I meant more like... building things that will change the world for the better."

"You have some time to spare, Dad?" He asked. "I have some ideas I'd like to share with you."

"Sure, Bruce. What do you have in mind?" Thomas replied.

"You can talk all you want after dinner," Martha interrupted, her voice firm but gentle. "It's time for a meal. I made your favorite, spaghetti and meatballs."

"Oh boy! Spaghetti and meatballs! My favorite!" Bruce exclaimed, his eyes sparkling with excitement. He ran to Martha and hugged her tightly.

Martha smiled and wrapped her arms around her son, hugging him close, "Come on now, let's go eat before it gets cold."

'Sometimes I forget, he is just a child. Three years old is still three years old,' Thomas thought, watching the scene with a smile.

After dinner, Thomas and Bruce sat down to talk while Martha went to the kitchen to clean up. Bruce took out a sketchbook and showed his father the designs of several inventions that he had been working on.

"These are the car models I have been working on," He said as he pointed to the drawings. "The first one is the Batmobile 1.0, the second one is the Batmobile 2.0, and the rest are all supercars."

"Hmmm, these are impressive, Bruce," Thomas remarked as he examined the drawings.

'Did he draw all these? Such details and creativity...' He mused in his thoughts as he studied the drawings intently. 'He must have spent a lot of time on these. He really is a remarkable child. All of these techs are too advanced for his age! Some of them don't even exist yet!'

"I know right? They are going to be awesome when I build them," Jack said with a grin. "The Batmobile 2.0 is going to be so fast, no one can catch up to it. But first I have to make the Batmobile 1.0 work properly."

"I am sure... Huh?" Thomas's eyes fell on a folded paper inside the drawing book. He unfolded it. It was some sort of blueprint of something. His brow furrowed in confusion. The blueprint contained scribblings, drawings, and formulas that were unlike anything he had ever seen before. Equations and symbols danced across the page, their purpose shrouded in mystery.

"Bruce, brush your teeth and go to bed," Martha's voice came from the kitchen.

"On it," He ran...

...brushing his teeth with a vigor that matched his youthful enthusiasm. As he stood on a stool in front of the bathroom mirror, he couldn't help but think how little he was. Who would have known that he would get another chance to live?

"I wonder how big this multiverse is? But since the Multiverse is real and I was reborn two times in a row, then there must be a way to travel between DC and Marvel universe and someone other than me might also have experienced this rebirth thingy," He mumbled to himself after washing his face. "If I can just figure out a way to travel between different dimensions... I might just be able to find my way back home..."
