Naruto: Madara is my Daddy

Itachi stared into his younger brother's tear-streaked eyes, a flicker of surprise cutting through his concern. There, in each of Sasuke's eyes, was a single, perfect tomoe, spinning against a field of crimson. The genuine, one-tomoe Sharingan.

"Sasuke, you've awakened your Sharingan!"

"Hmm? Really… is it true?" Sasuke wiped away his tears, his mind still reeling from the terror of the past few minutes.

Compared to Itachi's quiet excitement, Fugaku's expression was one of calm assessment. "Yes. I did not expect this 'spar' with Lord Madara would bear such unexpected fruit. The sheer terror and rage he felt must have forced his bloodline to awaken."

Slowly, the reality of it sank in for Sasuke. "Yes! I finally have the Sharingan!" he shouted, his excitement pure and unrestrained. With the Sharingan, he thought, his father would finally respect him as much as he respected Itachi.

"Alright, now is not the time for celebration," Fugaku commanded. "Itachi, follow me. We must heal the others. Sasuke, you come with me as well."

"Yes!"

A few hours later, under Fugaku's direction, all the injured Uchiha were carried back to their new quarters for treatment.

Meanwhile, at Madara's secret base, the ancient shinobi was preening. "Son, what did you think of your father's performance in the battle just now?"

"You were so cool, father!"

"Hahahahaha! When I have fully regained my youth, you will understand the meaning of true power! By the way, I have selected a few of the more capable ones from the clan to be your personal bodyguards and sparring partners. If you wish to go out and play in the future, you may take them with you."

At that moment, White Zetsu's form emerged from the ground. "Madara, Fugaku has brought three men to see you."

"Good. Let them in."

"Understood."

A moment later, White Zetsu led Uchiha Fugaku, Itachi, Inahiro, and Yakumi into the cavern.

"Lord Madara!" The four of them bowed as one, their voices resonant with a newfound, absolute respect. The power Madara had displayed had utterly subjugated them.

"I am quite satisfied with the four of you," Madara stated. "I plan to focus on your training personally." As he spoke, he gestured toward the massive, living statue carved into the stone wall. "You must be curious as to why I can use Wood Release. Look for yourselves. What do you see?"

The four men looked in the direction Madara pointed, their eyes widening in shock at the unmistakable face of the First Hokage, Hashirama Senju. "That's… the First Hokage!??" Fugaku exclaimed.

"Yes. It was cultivated from his cells. And I can transplant those very cells into your bodies."

"…!" Fugaku was stunned, his eyes darting away as if in resistance.

Madara sensed his hesitation and asked coldly, "Why? Do you not wish to gain the power of Wood Release? As the head of the Uchiha, you have surely read the stone tablet in the Naka Shrine. I can sense you have awakened the Mangekyō."

"When Uchiha and Senju unite as one, the power of all creation is born. With Hashirama's cells, your strength will become something entirely new."

"Lord… Madara," Fugaku began, his voice strained, "it is not that I am unwilling, but… I know of the experiments Konoha conducted with Hashirama's cells. A great number of elite ninja died. Even members of the Senju clan could not adapt, their bodies exploding as they were consumed by the power. It nearly drove the Senju to extinction."

"Humph!" Uchiha Madara scoffed with utter disdain. "No one knows Hashirama better than I. How can Konoha's crude, inferior research compare to the pure Hashirama cells I have cultivated?" He waved a hand toward White Zetsu. "This creature is a product of those cells. I will have him inject his own cells into your bodies. Once you have adapted, you will possess new powers."

"And those of you who possess the Mangekyō should understand that the more you use your eyes, the greater the strain, the closer you come to blindness. With Hashirama's cells, that will no longer be a concern."

"Whether you accept this gift or not is your choice. I will not force you." With that, Madara fell silent.

"Lord Patriarch! I… I want the transplant!" While Fugaku was still hesitating, Inahiro stepped forward, his eyes burning with a fierce resolve. "I want revenge! Revenge on Konoha! With that power, I will no longer fear them! The Uchiha have been trampled under their feet for too long. This time, I want to make them feel what it is like to be crushed!"

Uchiha Yakumi added, his voice firm, "Sir, I agree. If we do not fight back, we will never change our fate! Moreover, this is a gift bestowed upon us by our ancestor. I trust in his abilities!"

Fugaku pondered for a moment, then turned his gaze to Itachi, wanting to hear his son's opinion. Itachi remained silent, but in his heart, he had already made his decision. I will accept the transplant. Only with that power could he truly protect his brother in the future. Everything Itachi did, he did for Sasuke.
