"The fastest way would be to find this world's Bruce Wayne—if such a person exists here."
"Knowing myself, he'd never believe that Peter Parker's body contains the soul of another Bruce Wayne. So my best approach would be to knock him unconscious, imprison him, and keep him until I figure out how to return to my original world."
Batman turned his attention to what appeared to be Peter Parker's cobbled-together computer, with a shoebox serving as the case. It looked ramshackle, but fortunately ran smoothly. Batman quickly opened a browser and began searching various keywords.
As his fingers danced across the keyboard, Batman's expression grew increasingly grim. Finally, he stood and walked to the window, gazing at the traffic flowing through the streets below.
This world had no Gotham, no Metropolis, no Central City. There was no billionaire Bruce Wayne either. This wasn't a parallel universe—it was a completely foreign world.
There was no Kryptonian who crash-landed on a Kansas farm, no demigod princess from Paradise Island. Instead, there was some guy in red and blue spandex calling himself Spider-Man.
"Starting from nothing, with the timeline for returning indefinitely extended. But that won't stop me—because I'm Batman."
"I need money, facilities, equipment, gear, and complete control over this body."
Batman clenched his fist hard. He clearly remembered that sudden chill in Otto's lab earlier—the feeling that came just before the alarms sounded.
He wouldn't allow any abilities beyond his control to manifest. Since arriving in this world required starting from scratch, he had to formulate a comprehensive plan and keep everything under his command.
As he tightened his fist, Batman discovered something else: this body possessed tremendous strength, far exceeding his previous human limits.
While nowhere near his power in the Hellbat armor, he conservatively estimated around twenty tons of force.
This strength didn't make Batman feel lucky about crossing into a superior body—it made him extremely anxious.
Precognitive danger sensing, superhuman strength, mysteriously soul-swapping into this body, the fate of Peter Parker's soul... none of these things were under Batman's control.
Taking a deep breath, Batman immediately began searching Peter Parker's apartment.
Online information about Peter Parker showed only an ordinary college student. Batman needed to find more details about Peter from his living space.
Soon, a red and blue costume covered in web patterns, two wrist-mounted devices, a journal, and several chemical containers were laid out on Peter Parker's cluttered computer desk.
The costume looked identical to Spider-Man's outfit he'd seen online. Those two small devices were the tools Spider-Man used to shoot webs.
The journal was messy—the first few pages seemed to serve as scratch paper, covered in chemical formulas.
After careful examination, Batman determined these were the formulas for the web fluid in the shooters. The chemical containers held pre-mixed components that only needed proper proportioning to create the final solution.
The later pages contained Peter Parker's sketches—design drawings for the Spider-Man costume.
All evidence pointed to Peter Parker being Spider-Man.
As night fell, Batman had no intention of sleeping. He quickly located a nearby abandoned shipyard on a map, changed into Peter Parker's black clothes, and left the apartment.
"I need to fully understand this body's speed, strength, reflexes, and senses, but right now I can only test strength and speed."
The abandoned shipyard looked eerie and frightening in the darkness, creaking and groaning whenever wind passed through.
Exposed pipes reeking of stagnant water and piles of industrial waste made this a place even beggars wouldn't visit.
Batman's luck held—he found a rusted gantry crane with over a dozen counterweight blocks scattered around it.
After testing, his strength peaked at twenty-five tons in normal conditions. Speed-wise, with superhuman power backing him, he could sprint at 190 km/h.
Batman also discovered that regardless of obstacles or terrain complexity, his reaction speed could handle everything effortlessly.
With these physical capabilities, Batman couldn't help but glance at the web shooters he'd brought along.
Recalling footage of Peter Parker's graceful aerial swinging, Batman's mouth twitched. After a moment's hesitation, he strapped the web shooters to his wrists.
Two minutes later, an uncomfortable-looking Batman removed the web shooters. Despite having used similar grappling guns, he couldn't adapt to Peter Parker's overly flamboyant web-swinging style.
"With special technique, both strength and speed could reach another level."
Batman silently recorded all data about this body while formulating a complete training regimen.
He wouldn't abandon training just because Peter Parker's body was so powerful—in his mind, none of this strength truly belonged to him.
Muscle memory, conditioned reflexes, combat techniques—Batman needed to retrain everything.
Over the next three days, aside from necessary one or two hours of sleep, Batman spent days wandering New York's streets learning everything about this world, while nights found him in black clothes at the abandoned shipyard, relentlessly training his body.
Using his Empire State University student identity, Batman secretly used the school laboratory to analyze his blood composition and test everything about this body—healing factor, sensory acuity, and more.
From the traces Peter left behind, Batman had uncovered the source of all this body's abilities: a genetically mutated spider.
Even that intangible "danger sense," Batman found referenced in Peter Parker's notes under the name "spider-sense."
"From a scientific perspective, this ability results from the brain's extraordinary, subconscious-level processing of micro-environmental changes, ultimately projected into consciousness as 'warnings.'"
"In that case, I can develop targeted training for it."
Deep in the abandoned shipyard, Batman had cleared out a warehouse. A large New York City map covered one wall.
Over fifty colored pins of various hues dotted the map, while newspaper clippings and handwritten character profiles surrounded it.
These represented New York's currently active major criminal organizations. Batman stood with arms crossed before the map, as if he'd marked all of New York as his hunting ground.
"Experimenting and building equipment capable of precisely locating my original world will require massive funding and facilities. I need to build from nothing—establish a commercial empire like Wayne Enterprises in New York to support this endeavor."
"Dr. Otto's fusion energy presents a solid business opportunity, but I need startup capital to enter the game."
"My first fortune will come from these gangs."
