This story is inspired by JP-Ryder's story and the New 52 movies. It just came to my head that Danny and Bruce Wayne has some similarities, with the blue eyes and black hair, so Danny will be twins with Damien in this story. Also, all of this will be set on the New 52 movies, like Son of Batman, Justice League vs Teen Titans, etc. So, enjoy the new story.

Edit: Since it's my birthday today, I decided to post this as a birthday present for myself. So I can read it whenever there's nothing to do.

Disclaimer: I don't own anything in this story.

Prologue: Heir of the Demon

"Daniel!" an elderly voice said, walking through the halls of his home. His wisdom-filled, green eyes looked around the grand hall. He was an old man, with graying hair and a beard, but despite that, he radiated strength and stature. He was also dressed in a royal green robe and battle armor underneath.

He was Ra's al Ghul, the leader of the League of Assassins, and someone born six hundred years ago.

"Daniel, where are you?" he called, looking for his grandson. "Honestly, that boy."

"Is something wrong, Grandfather?" a voice said behind him.

Ra's turned and saw his older grandson. A young boy about twelve years asked, looking at his grandfather. He was tall for someone his age, with piercing green eyes and black hair, dressed in royal green robes and battle armor underneath.

"I am fine, Damian," Ra's said to his grandson. "I am just looking for your younger brother."

Damian frowned at that. Even though he was right here, Ra's was still more focused on his twin brother, even though he trains harder than him.

Ra's looked at Damian and frowned. It's not that Damian wasn't weak. In fact, if Daniel wasn't born, Damian would be the perfect heir, with how fast he learned and how hard he trained. Damian could beat ten adults all on his own, unarmed.

But he knew Daniel was stronger. He could feel it in the boy, a power he hasn't felt for so long. That was why he wanted him to become the new leader of the League. Though the boy was special, he was nothing like his brother. Unlike Damian, who was ruthless and merciless, Daniel wanted nothing to do with the league. He didn't want to kill, he avoided training, and he never went to his studies. If only he was like Damian, then he would have been the perfect heir.

"Go to your studies, Damian," Ra's said as he started walking. "I need to find your brother."

"…Yes, grandfather," Damian said before walking away, glaring at the ground. No matter what he did, it was always Daniel. He clenched his fists as he walked to the library.

He will be the new leader of the League of Assassins. Even if he had to get rid of Daniel one way or another.

Meanwhile, a boy was sitting in a forest, feeding the birds, smiling as the birds perched on his shoulders. He had shaggy, black hair and blue eyes, dressed in green robes and battle armor. He gently petted the robin, causing it to chirp happily.

"So, hiding again?"

He froze when he heard that voice. He slowly turned and saw a beautiful woman in a black, tight suit and gloves. She had auburn hair, green eyes and tanned skin, staring at him. The birds flew off him as the woman walked towards him in a stern fashion.

"M-mother…" he said sheepishly as he stood up, looking at the ground.

The woman looked at him sternly before smiling softly. She patted his head, causing him to look at her.

"Danny, you must stop running from your studies," Talia said, using the nickname she gave him. She was the daughter of Ra's al Ghul and was the second-in-command of the League of Assassins. "Your studies are important."

"…But I don't want to," Daniel said, looking away. "Grandfather would try to talk to me about killing. You know I don't want to kill."

Talia frowned slightly as she looked at her son. Despite being raised by assassins, he would refuse to kill. Whenever the two brothers trained, Damian would kill the opponent while Danny would just knock them unconscious. Whenever they train, Daniel would do it halfheartedly, but she knew he could do more than that.

Honestly, he reminded her of his father.

"C'mon, son," Talia said, gently grabbing his arm. "Let us go home."

Daniel let his mother lead him back to their home. He sighed as he looked at the imposing castle. His thoughts then wandered to his father. He never met him, but he heard a lot from his mother. A man from Gotham that gained the attention of Ra's al Ghul, a man who fought for Justice, a man he wanted to become.

The Batman.

And the prologue ends here. As you can see, Damian and Daniel do not get along well, with Damian jealous of Daniel getting their grandfather's attention. Hope it's a good start for you guys. Next chapter will be longer, promise.

Oh, and before I end the chapter, wanna let you guys know of a new story called Meridian Jinchuriki by pyrohelixdrago. It's a good read. Makes me want to do a DP x WITCH story someday.

Next chapter; the son escapes, Daniel vs the League of Assassins. See you later!
