Natsu Uchiha (On Hold)

Prologue

Natsu Dragneel opened his eyes expecting to see Jellal standing across from him, but what he saw was not at all what he was expecting.

He found himself in a forest, except this was the forest that Igneel had raised him in. Everything was the same, except there was a red moon casting a red light as far as his eye could see with a cloudy atmosphere, giving the background a blood-red appearance while everything else within was depicted in an inverted grey scale. He looked down to see that his body was also grey.

The Dragon Slayer looked around in confusion since the last thing he remembered was Simon dying by protecting him and Erza and then eating the Etherion before blacking out.

He was snapped out of his musings by a cold voice from behind him.

"So, this is what has become of me? Pathetic. I just hope this is some kind of joke."

Spinning around, Natsu was startled to see someone else here. He spotted a man who stood in the clearing with his arms crossed and shivered; the man's aura was even greater than Igneel's! He inspected the man and took in his appearance. He was a tall, fair-skinned man with spiky, black hair that had a slight, blue tint to it. His hair was waist-length with shoulder-length bangs framing the sides of his face, covering his right eye entirely. Although relatively young, more prominent creases were developed under each of his eyes. His attire took the form of bright red traditional armor, similar to that of samurai, worn over a simple black suit. This armor was constructed from numerous metal plates, formed into multiple protective guards along his body, in particular: chest, waist, shoulders and thighs. Unusually, his chest plate left his back entirely exposed. This clothing was accompanied by boots and gloves, as well as a strange forehead protector.

"W-Who are you?" Natsu nervously asked the man.

The man looked indignant at the question, "My God, is this really what's become of me? A stuttering fool who acts like that Uzumaki boy? And not to mention his hair! Seriously, if you're somehow related to that useless Haruno wench, I will kill both of us."

"Oi! What the hell wrong with my hair! And you didn't answer my question bastard!" Natsu yelled at the man.

"Keep your voice down and drop that insufferable attitude!" The man harshly told Natsu causing him to tense and sigh before his face adopted a look similar to that of the raven haired man in front of him.

"So you knew that my personality wasn't real?" the man nodded and Natsu continued, "How? No one, not even Master has figured it out."

"My name is Madara Uchiha, co-founder of the mighty Uchiha Clan, one of the most powerful shinobi in the entire world, and most importantly... I am you." The man, now identified as Madara told the young Dragon Slayer who was shocked at the information.

"B-But how could you be me!?" Natsu asked as he couldn't understand what the man just said.

"There are many things in this world that are hard to explain, this is one of those things. You see, you are my reincarnation. From what I guess, I was chosen to be reincarnated into you so that I could have a second chance at life, and atone for my past sins." Madara responded with a wistful look on his face.

"Past sins?" Natsu asked his former self.

"Now that is a long story..." Madara sighed before telling Natsu about his life. He told him everything from his childhood and meeting Hashirama to starting the Moon's Eye Plan and using his grandson, Obito Uchiha, to act as him and prepare everything from forming the Akatsuki and gathering the Bijuu. After that, he told him about when he was brought back to life and almost took over the world if it wasn't for one Naruto Uzumaki, a boy who not only defeated Madara, but changed his heart as well. "And after that, I released the jutsu I used to keep my body after the Edo Tensei was broken and returned to the afterlife."

"That's all well and good, but why am I here? Why did you decide to appear now?" Natsu questioned before the world around him shook causing him to lose his balance. He looked around and noticed the world around him crumbling. "What's going on!?"

"After you ate that Etherion substance, you gained tremendous power, but your body cannot handle it all the way it is right now. That's where I come in. Once you realize who you are, and we merge, you will awaken power unlike any ever seen before in this world! Once you awaken this power, the heavens themselves will tremble at your feet! But you will only gain this power if you tell me why. Why do you want power!?" Madara asked the Dragon Slayer.

"To protect my friends!" Natsu immediately answered before Madara gave him a harsh glare.

"Don't lie! Give me the REAL reason."

Natsu hesitated for a second, "I want to make Jellal pay for what he's done."

"Stop giving half truths. There's more to it than that. There's a reason why you hate him so much, and it's because of what he did to that girl."

Natsu flinched at that. He knew that what Madara said was true, but he never wanted anyone to know. He never wanted anyone to know about his secret love for her.

"I..." Natsu clenched his teeth as he answered, "I want to make him pay because of what he did to her. I want to punish him because of all the pain that he caused her! I want to defeat him because he made her cry! He deserves to suffer for hurting the woman I love... for hurting Erza!" there was so much conviction in his voice that Madara could swear that he could see Naruto Uzumaki again.

Natsu was glaring at Madara for making him announce his love for Erza. He's loved Erza ever since he met her, but he never knew how to express it since he never had human interaction before joining Fairy Tail. He loved everything about her from her beautiful red hair, shining brown eyes, and her intoxicating scent. He loved her strong personality, which was why he couldn't bear to see her cry, and why he vowed to make Jellal rue the day he hurt her.

Madara smiled at his reincarnation, "Good, now when we merge I have a request for you."

"What's your request?"

"I want you to add Uchiha to your name, and I want you to revive the Uchiha Clan with this Erza girl you love." He chuckled when Natsu blushed.

"Fine." Natsu grumbled. Madara chuckled before turning serious.

"When you leave this place, you will gain the most precious possession of the Uchiha Clan, the Sharingan." Madara said before his eyes shifted and became red with three tomes in each causing Natsu's own eyes to widen.

"What do they do?"

"Oh, you'll remember." Madara said causing Natsu to growl. "Goodbye Natsu, remember to bring glory back to the Uchiha Clan. That's all I ask."

Natsu nodded before he disappeared from the red world.

Madara sighed before staring up at the red moon. "Who would've thought that my reincarnation would fall in love with a descendant of the Uzumaki boy." He chuckled thinking about it. "It seems even now, I can't get away from that clan." He mused before closing his eyes and letting the world around him become white and engulfed him.

"Show him love, Erza Uzumaki."

Tower of Heaven

Erza Scarlet and Jellal Fernandes watched in shock as a bright purple light engulfed Natsu after he ate the Etherion. They shielded their eyes and shivered at the dark feeling coming from the light and looked as it died down. Their eyes widened in shock when they saw who they assumed to be the Fire Dragon Slayer.

Natsu no longer looked the same. His face was now much more angular and handsome and he appeared to have grown taller. His pink hair was now a much darker shade pink and reached past his shoulder blades, and had two bangs framing the sides of his face and his forehead. He was also wearing red armor that looked like it belonged to a samurai. He opened his eyes causing Jellal to step back and Erza to gasp.

Natsu glared at Jellal with red eyes that had two tomes in the right and one in the left. "Sorry about making you wait... I hope you're ready to accept your punishment now."

And that's when all hell broke loose.
