MHA: GOKU BLACK

After the intense hijacking incident, Goku Midoriya arrived in New York with a renewed sense of purpose. The city, bustling with life, was a stark contrast to the peaceful streets of Japan he had left behind. Towering skyscrapers lined the horizon, their glass windows reflecting the orange hues of the setting sun. The air buzzed with energy, and Goku could feel his Saiyan instincts stirring at the challenge the city seemed to offer.

As he stepped out of the airport, he adjusted the strap of his backpack and took a deep breath. "Time to see what this city's really made of," he muttered, his green eyes scanning the streets.

A City in Need

Over the next few days, Goku explored the city, taking in its sights and learning about its people. He quickly noticed that while heroes were present, crime was rampant in the shadows. Gangs, street thugs, and small-time villains preyed on the weak, often avoiding the notice of heroes who were busy with larger threats.

One evening, Goku stood atop a rooftop overlooking a dimly lit alley. His heightened senses picked up muffled cries for help. His sharp eyes zeroed in on the source—a young woman being cornered by three men.

"You picked the wrong street," one of the men sneered, pulling out a knife.

The woman backed up, her hands trembling. "P-please, just take my wallet and leave me alone."

Goku's Saiyan blood boiled. He didn't need a license or anyone's permission to do what was right.

Without a sound, he leaped from the rooftop, landing in the alley with a soft thud. The thugs turned to face him, startled.

"Hey, kid," one of them growled. "Mind your own business, or you'll get hurt."

Goku's expression was calm, but his eyes gleamed with determination. "Three against one? That doesn't seem fair. How about I even the odds?"

The thugs laughed, clearly underestimating him. "You've got guts, kid," the leader said, cracking his knuckles. "But you're in over your head."

The First Fight

The first thug lunged at Goku, swinging his knife in a wide arc. Goku sidestepped effortlessly, his movements fluid and precise. Before the thug could react, Goku delivered a sharp jab to his stomach, sending him sprawling to the ground.

The second thug rushed in, wielding a metal pipe. He swung it with all his might, aiming for Goku's head. Goku ducked under the swing and countered with a spinning kick that knocked the pipe from the man's hands. A quick follow-up punch to the jaw sent him crumpling to the pavement.

The leader, clearly more cautious now, activated his quirk. His hands began to glow with a faint red light as he smirked. "You're not dealing with an ordinary thug, kid. My quirk lets me turn anything I touch into an explosive. Let's see how tough you really are."

He lunged at Goku, aiming to grab his arm. Goku dodged, keeping his movements light and agile. He could feel the heat radiating from the man's hands and knew he couldn't let himself get caught.

"You've got a flashy quirk," Goku said, dodging another explosive swipe. "But you're too slow."

With a burst of speed, Goku closed the distance between them, landing a powerful uppercut that sent the leader flying backward. The man crashed into a pile of trash cans, groaning in pain.

The young woman watched in awe as Goku turned to her, offering a reassuring smile. "You're safe now," he said.

She nodded, still shaken. "Thank you. Who are you?"

"Just someone trying to help," Goku replied, turning to leave before she could ask more questions.

The Birth of a Vigilante

Word of a mysterious figure taking down street-level criminals began to spread in the darker corners of the city. Some called him a hero, while others referred to him as a vigilante. Goku didn't care for titles; he only cared about making a difference.

He spent his nights patrolling the city, taking down small-time crooks and helping those in need. His Saiyan strength and instincts gave him a significant edge, and he quickly became a ghost story among the criminal underworld.

One night, as he perched on a water tower overlooking the city, he felt a faint ki signature approaching. His instincts tensed as a man in a black mask and hood appeared behind him.

"You've been busy," the man said, his voice calm but firm. "Taking down thugs, helping people... not bad for a rookie."

Goku turned to face him, his expression unreadable. "Who are you?"

The man chuckled. "Name's Nightblade. I've been watching you. You've got potential, kid, but you're reckless. You keep this up, and you'll get yourself killed—or worse, someone else."

Goku crossed his arms. "And what makes you think you know better?"

Nightblade stepped closer, his presence imposing. "Because I've been doing this for years. Being a vigilante isn't just about strength; it's about strategy. If you're serious about this, you'll need to learn how to think like a shadow."

Goku raised an eyebrow. "And you're offering to teach me?"

Nightblade nodded. "You've got raw talent, but you're rough around the edges. Stick with me, and I'll show you how to survive out here."

Training with Nightblade

Over the next few weeks, Goku trained under Nightblade's guidance. He learned how to use the city to his advantage—how to blend into the shadows, track criminals, and gather intel without being noticed. Nightblade also emphasized the importance of control, teaching Goku how to harness his strength without causing unnecessary destruction.

"You've got power," Nightblade said one night as they sparred on a rooftop. "But power without control is just chaos. If you want to protect people, you need to learn how to hold back."

Goku nodded, absorbing every word. His Saiyan instincts often pushed him to fight at full strength, but he knew Nightblade was right. If he wanted to be a hero, he needed to master restraint.

A New Threat

One evening, as Goku and Nightblade were patrolling the city, they came across a warehouse with suspicious activity. Inside, a group of men was loading crates onto a truck. Nightblade gestured for Goku to stay quiet as they observed from the shadows.

"Looks like a weapons deal," Nightblade whispered. "Stay sharp. These guys won't go down easily."

As they moved closer, one of the men spotted them. "Intruders!" he shouted, and the group sprang into action.

Nightblade moved like a phantom, taking down two men with swift, calculated strikes. Goku, meanwhile, charged headfirst into the fray, his fists blazing with energy.

The leader of the group stepped forward, activating his quirk. His body began to shimmer as he transformed into a metallic form.

"My quirk makes me invulnerable," the leader boasted. "You can't hurt me, kid."

Goku smirked, his Saiyan blood surging with excitement. "We'll see about that."

The battle was intense, with Goku trading blows with the metallic villain. His punches landed with enough force to shake the ground, but the man's hardened body absorbed most of the impact.

"You're tough," Goku admitted, dodging a powerful swing. "But I've fought tougher."

He powered up, his golden aura flaring around him. With a burst of speed, he delivered a devastating punch to the man's chest, cracking his metallic form. The villain staggered, his confidence shaken.

Nightblade finished off the remaining thugs and joined Goku, his expression impressed. "Not bad, kid," he said.

Goku grinned. "Thanks. But I think I still have a lot to learn."

Nightblade nodded. "Then let's keep moving. This city isn't going to protect itself."

His Vigilante Arc has begun.

(Please note that his Power level is around 20,000 .He can top 20 in hero system strength wise. Prime All might is around 100,000. )
