Chapter 1: The Visit of the Estranged Father

The summer sun cast a warm golden hue over the quiet streets of New Jersey. Harry, dressed in casual attire, walked briskly home from the dojo, his mind still filled with the day's training and the principles of self-discipline he had learned.

"Sensei is really putting us through the ringer," he muttered to himself, lost in thought.

Approaching his two-story suburban home, Harry noticed the well-manicured lawn, neatly trimmed bushes, and the familiar white picket fence that bordered the property. The house itself was a charming brick-front colonial with large windows framed by navy blue shutters. A porch spanned the front of the house, complete with a wooden swing where Harry would often sit to sketch or listen to music.

As he unlocked the front door and stepped into the hallway, the tension in the air was palpable. Raised voices echoed from the living room, and Harry quickened his pace. Dropping his bag by the entrance, he moved to intervene in the heated argument between his Aunt Petunia and a tall figure with jet-black hair – his estranged father, James Potter.

"Petunia, he needs to come back with me. It's for the family," James insisted, his voice stern.

Harry's eyes narrowed as he confronted his father. "What's going on? Why are you here?" he demanded, his hand unconsciously clenching.

James looked at his eldest son, his face a mix of regret and urgency. "Harry, it's about your younger brother, James. He's being slandered by the Daily Prophet, and the Minister of Magic is backing them. He needs your support."

Feeling a surge of anger and disbelief, Harry retorted, "After everything, you want my help now?" Memories of neglect and mistreatment flooded back as he spoke.

James sighed tiredly, "We will talk later. I need you. Your brother..."

Aunt Petunia glanced anxiously between the two Potters, her face pale. "Harry, please," she whispered, her voice trembling.

Harry took a deep breath, trying to rein in his anger. "I'll come back," he finally said, "but on one condition – I continue my muggle studies, and you keep your distance from Aunt Petunia."

James hesitated, clearly torn between his desire for family unity and his own prejudices. After a tense moment, he nodded, "Agreed."

A tense silence filled the room as James looked taken aback by Harry's words, his face flushing with a mix of anger and shame. Aunt Petunia looked on, her eyes filled with concern and sadness.

"When do we leave?" Harry asked, looking at his biological father with an annoyed expression.

"Tomorrow night," James replied, his face crestfallen.

Harry nodded, picking up his bag and heading to his room to pack his belongings. As he packed, his mind raced with the complexities of the situation and the challenges ahead.

His room was a typical teenage boy's space – a single bed with a simple blue comforter, a desk cluttered with school books and stationary, and a small bookshelf filled with novels, comics, and a few trinkets. Posters of bands and athletes adorned the walls, and a guitar rested in one corner, a testament to Harry's muggle interests.

"Great way to spend my summer. Being Junior's support animal," Harry muttered, annoyed by having his summer hijacked by his biological father, no less.

"Harry!"

Harry paused in his packing and looked back to see his Aunt Petunia in the doorway, looking at him with a pained expression.

"Harry," Aunt Petunia began, her voice softening, "are you alright?"

Harry paused in his packing, looking up to meet his Aunt's concerned gaze. "No, I'm not," he admitted, his voice slightly shaky.

Aunt Petunia sighed, taking a step closer to her nephew. "I know things have been difficult between you and your father. But your brother needs you now. He's facing a lot of scrutiny and false accusations. You have the power to make a difference."

Harry sighed deeply as he finished packing, zipping up his bag and placing it beside his bedroom door. He looked around his room one last time, taking in the familiar surroundings that had been his sanctuary from the chaotic world of magic and family drama.

He sat down on his bed, running his hands through his hair in frustration. The weight of the situation was heavy on his shoulders, and he felt trapped between his loyalty to Aunt Petunia and the unwanted responsibility to support his younger brother, James.

"You don't have to face this alone, Harry," Aunt Petunia said softly. "Your father may not have been there for you in the past, but you have a chance to make a difference now. And remember, I'll always be here for you."

"Thank you, Aunt Petunia," Harry whispered, touched by her words of comfort.

The evening passed in a blur of last-minute packing and silent contemplation. Harry tried to distract himself by immersing in his comics and music, but his mind kept wandering back to the upcoming reunion with his estranged family.

The next day, Harry, with his bag slung over his shoulder, stood talking with Aunt Petunia in the living room.

"Harry, promise me you'll be careful," she said, her voice shaking slightly.

"I promise, Aunt Petunia. I'll be cautious," Harry replied, giving her a small smile.

"Just remember, Harry, no matter what happens, you are loved and valued. Don't let anyone make you feel otherwise," she said, tears glistening in her eyes.

"Thank you, Aunt Petunia. That means a lot to me," Harry said, feeling a lump in his throat.

Just then, James entered the room, carrying a small bag. His expression was somber, and he avoided making eye contact with Harry.

"It's time to go," James said curtly, his voice devoid of emotion.

Harry took a deep breath, bracing himself for the challenges ahead. With a final nod to Aunt Petunia, he followed his father out of the door and into the unknown.

James reached into his pocket and pulled outa small, ornate object - a portkey. It was an old boot, worn and faded from years of use.

"Ready, Harry?" James asked, his eyes searching Harry's for any sign of hesitation.

Harry nodded, taking a deep breath to steady himself. "As ready as I'll ever be," he replied, gripping his bag tightly.

James grabbed Harry's arm and held out the portkey for both of them to touch.

"On three," James instructed. "One... Two... Three!"

As soon as they made contact with the portkey, a powerful tug pulled at Harry's navel, as if a hook had caught him from the inside. The world around him blurred into a whirl of colors and shapes, the sensation of being squeezed through a tight tube overwhelming his senses.

Within seconds, the chaos subsided, and Harry found himself standing in the grand entrance hall of the Potter mansion. The opulence of the place was staggering - high vaulted ceilings, glistening chandeliers, and walls adorned with priceless works of art. A grand staircase spiraled upwards, leading to the upper levels of the mansion.

Harry blinked, trying to adjust to his new surroundings. He glanced over at James, who looked equally disoriented but quickly regained his composure.

"We're here," James said, his voice echoing slightly in the vast space of the hall.

Harry took a moment to take it all in, the weight of the situation pressing down on him. He was back at a place where he didn't have fond memories, as they were filled with neglect, resentment, and anger.

Harry couldn't help but say dryly, "There's no place like home." He looked at the mansion that he once called home with disdain.

James looked at Harry, his expression a mix of guilt and sadness. "I know this is hard for you, Harry. But we need to put aside our differences and work together for the sake of the family."

Harry sighed, running a hand through his hair. "Let's just get this over with."

Note : Here is the first chapter of my chapter of my Dc Universe with Harry as Batman and I apologized for sudden reboot of my old story.
