Marshall D. Teach

Marineford Era 1494, the New World, an island called Asuka.

Deep in the mountains and forests, a giant tiger, eight meters long, stared at its prey. Drawn by the scent of blood in the area, it saw only a small human and the corpse of a ferocious bear beside him.

Its natural instincts allowed it to sense a trace of threat from the young human, but that was all. It paced, circling him halfway, but slowly closing the distance. The boy remained motionless, seemingly without the strength to resist, likely exhausted from his battle with the ferocious bear.

This thought made the tiger less cautious. One step, two steps. The moment it reached optimal hunting distance, it seized the opportunity. "Roar!" it bellowed excitedly, lowering its body slightly, and lunged fiercely at the boy.

"Fufufu! Finally making your move!" The boy had been watching its every move, waiting for his chance. Seeing the giant tiger attack, a sharp glint flashed in his eyes. He pushed off the ground with his legs, leaping up with even greater speed. The intense recoil caused the ground beneath his feet to slightly sink, kicking up dust and stones. In that instant, the boy's figure appeared in front of the giant tiger. The tiger's pupils contracted. "Fufufu! Yaochi-onna." An excited, wicked grin spread across the boy's face.

His hands formed claws, his arm muscles bulged, and silence fell. Ten bloody claw marks flashed through the air.

The boy fell from mid-air. The giant tiger's massive body crashed heavily to the ground behind him with a tremendous sound, falling silent.

The boy's hands were stained with blood, crimson droplets falling from his fingers to the ground. On the giant tiger's corpse, across its abdomen, were ten ferocious claw marks, similar to the wounds on the ferocious bear beside it.

Night had fallen deep. A campfire crackled in a clearing in the forest, where the boy was roasting a giant bear paw.

Watching the flames before him, the boy's thoughts drifted. "I'm twelve now, it should be soon." He seemed to be waiting for something.

He hadn't expected to arrive in the world of One Piece and become the future big boss, the ambitious Marshall D. Teach. No sudden death by electrocution, no cheat system, just a sleep, and when he woke up, he was a six-year-old Teach, the future Blackbeard.

He knew One Piece very well. In the anime, Teach boarded Whitebeard's pirate ship at the age of twelve, at which point he was just a weak fisherman.

This was undoubtedly a waste of his talent. When he woke up, he had perfectly merged with Teach's original memories. He also gained a deeper understanding of his own abnormal physique, possessing terrifying vitality and monstrous strength from birth. The side effect was an inability to sleep, but this didn't affect Teach, as he was full of energy and could dedicate more time to training.

For the past six years, Teach had been rigorously training his body, understanding the horrors of this world and truly grasping the importance of strength. Not knowing how to cultivate Haki, he focused all his training on taijutsu and swordsmanship. As for the swordsmanship manuals, he stole them from a declining dojo on the island. Decades ago, it had been renowned, founded by a powerful swordsman. After that swordsman's death, no strong swordsmen emerged, and it gradually declined.

The inheritor of the dojo had even wanted to sell it. It only took a short time for him to easily acquire the treasured swordsmanship manuals and the swordsman's notes.

He carefully examined the swordsmanship manual. It was a complete and undamaged manual on Lightning Current Sword Technique. Lightning Current Sword Technique was a very prominent school of swordsmanship, as famous as Flame Flow Swordsmanship, capable of unleashing powerful slashes imbued with lightning and flame, greatly enhancing their destructive power.

A core element was a breathing technique that could be used in conjunction with the swordsmanship, which he called the Thunder Breathing Technique. Breathing techniques were common in the world of pirates; some powerful taijutsu had accompanying breathing techniques, such as the Flower Country's Happo Navy's secret Hasshoken, and Lao G's Di Weng Fist.

The Thunder Breathing Technique was the core of this Lightning Current Sword Technique. It used breathing to generate electricity within the body, which had strong side effects, causing swordsmen from this dojo to be short-lived.

This breathing technique was very suitable for Teach. With his monstrous talent and abnormal vitality, the side effects had little effect on him. He could also use the bioelectricity generated by the breathing technique to strengthen his physique, especially his internal organs.

Teach possessed a rare talent for cultivating swordsmanship, a result of the fusion of two souls. Perhaps he had had this talent himself, but it wasn't developed in the original story.

Being too young, his strength improvement was limited by his physical body, so he set his sights on swordsmanship. Teach had been practicing swordsmanship for four years now. He was also training at another dojo on Arcas Island, whose master was a Flame Flow swordsman. He learned the basics of swordsmanship there.

After a hearty meal, only clean bones remained, larger than Teach's own body.

Closing his eyes, Teach sat cross-legged on the ground, inhaling and exhaling as if resonating with nature. Arcs of electricity flickered across his body, and the surrounding air grew hot, the temperature rising. This was Flame Flow Swordsmanship, taught to him by the Flame Flow swordsman Hael, who could also be considered Teach's first sword instructor. After Teach displayed his talent, he laid a solid foundation in swordsmanship in just two years. Once he became a swordsman, Teacher Hael taught him without reservation.

"Haa!" Heat radiated from Teach's body, and the ground beneath him seemed to scorch, becoming searing hot, as if about to erupt in flames. Lightning and heat intertwined, tempering Teach's physique. To unleash more powerful lightning and hotter flames, he had to be able to withstand them himself.

Of course, there were other methods, such as generating flames by rubbing air at extremely high speeds, not touching the flames himself, but having them attach to the blade to unleash flame-like slashes. This was the mainstream method on the seas, exemplified by Kanjuro, a samurai from the Land of Wano who appeared in the anime.

Teach's method was more extreme; without a sufficiently powerful physique, one could not endure it. The goal was to combine swordsmanship and taijutsu, to unleash a swordsman's slashes without a sword, using his own hands as blades.

After all, taijutsu was fundamental. It was precisely because of this that Teach's claw techniques were incredibly powerful. If there were a machine to measure energy, it would show that the temperature and electrical intensity in Teach's hands exceeded that of his body. Teach plunged his hands into the burning campfire, enduring the stinging sensation, using the flames to aid his training. This training was agonizing at first, but he gradually grew accustomed to it.

Sunlight shone upon the land, in Arcas Town. "Teach, didn't I tell you to be careful last time? How did you get injured again?" In the town's renowned medical clinic, a young girl looked angry, but her hands didn't stop. White bandages were wrapped around Teach's burnt arm, layer by layer.

"Fufufu, Monica, I accidentally set a tree on fire while barbecuing outdoors. It took a lot to put it out, otherwise, the whole mountain would have been gone." Teach threw his head back and laughed heartily. "I almost got burned to death, fufufufu!"

Seeing Teach's apparent disregard for his own life, Monica applied more pressure with her arm. "Zzzt!" "Ouch, ouch, ouch! Gently, Monica." Teach straightened his back, as if about to spring up from the ground. "Hiss!" His eyes widened, clearly in pain.

Seeing Teach like this, Monica narrowed her eyes, covered her mouth with her hands, and smiled. Then, she gently applied herbal medicine to his hand and tied the bandage.

"Fufufu, thank you so much. If it weren't for you, my hand would be ruined. If my hand is ruined, I can't go out to sea and become a great pirate," Teach said, standing up from the chair and looking out the window at the vast blue sea. He spread his arms wide and shouted out the window, "A person's dreams will never end!"

Looking at the boy's back, Monica was momentarily stunned, lost in thought. His somewhat strong physique, his outstretched arms, seemed to embrace the entire sea. Her heart began to beat faster, she didn't know when.

Turning around, "Ah, it hurts!" Teach frowned, returning to his seat. He had moved too much and accidentally torn the wound. "Idiot, I just finished bandaging that." Monica gritted her teeth, seeing Teach like this, and twisted his ear with one hand.

"Gently, it hurts, Monica. Be ladylike, don't be so violent, or you'll never get married." Monica let go immediately, crossing her arms. "Hmph! Serves you right for not learning your lesson." She said, turning her head to the side.

"Okay, okay, it's my fault, I won't do it again." Knowing Monica was angry, Teach comforted her with a smile.

He grabbed Monica's shoulders, turning her so her gaze met his. Although only twelve, Teach was already one meter seventy tall, with slightly curly, neatly combed black hair. His body, strengthened by years of training, was robust, his firm chest muscles straining his shirt. His face was still somewhat youthful but filled with masculine vigor. A faint, wicked smile played on his lips, and he exuded a mysterious aura, a certain charisma.

Being stared at like this, Monica, being rather shy, couldn't hold on for long. After all, she was only fifteen. Her small face flushed slightly, and she pushed against Teach's chest with her hands.

"Fine, I forgive you." She had always taken great care of Teach, treating him like a younger brother. In recent days, she had developed different feelings for him, especially after Teach changed.

Teach understood Monica's personality very well; she was a very gentle yet somewhat lively girl.

Seeing her like this, Teach couldn't help but smile. "Fufufu, Monica, the medicines these days are quite expensive, aren't they? I can't afford the medicine. Not a single bit of medical expense. If Uncle Mody knew, he'd probably beat me up."

"You can't speak about Father like that, Father is very gentle," Monica said, shaking her head as Teach badmouthed her father.

"I owe you more and more now, how can I repay you?" Teach smiled, looking at Monica's delicate face and beautiful long golden hair. Monica froze upon hearing this, her heart pounding.

Suddenly, Teach's expression changed. "Not good, a killing intent." "You damn Teach, daring to tease my daughter again, die!" The voice came from far above, the sound preceding the sight. It was too fast. Teach couldn't react. He narrowed his eyes, trying to see more clearly. He only caught a glimpse of a faint dark shadow flashing past the staircase. A terrifying aura emanated from afar, palpable even from a distance. Instinctively, he raised his arms, crossing them in front of him.

The next moment, a figure appeared before Teach. A powerful punch, evading Teach's arms at a strange angle, landed squarely on Teach's chest. "Pfft!" Teach's eyes bulged wildly. A gust of air was forced from his mouth, and he was sent flying backward in a straight line, crashing through the door and into the wall of the courtyard. "Boom!" The solid wall caved in, covered in spiderweb-like cracks, and fragments of stone rained down.

"Teach!" Monica cried out, turning to look at the man who had appeared where Teach had been standing. He had short blonde hair, wore a white lab coat, and sported square glasses. Standing at two meters forty, his white coat billowed from his previous movement. "Dad, you hit too hard! Teach is still injured!"

"Hmph! Monica, you underestimate that kid," Mody, Monica's father, said displeased. He glared in Teach's direction with ill intent. Seeing Monica's worried expression, he felt like his long-nurtured "little cotton jacket" was being stolen.
