Hey! This is Deathslayer Night, writing my first solo Fairy Tail fanfiction! I wanted to write a story about Acnologia raising Natsu as his son a while back. But I saw that a few others already wrote down that idea in the fanfiction website, so I ditched the idea and started reading those. Now, I realized that they haven't actually written down how Natsu should act like if he was raised by Acnologia the way I'd like. Sure, Eye of the Black Dragon and Wrath of the Insurgent Dragon Slayer are really good, but I want to see if my version of Natsu as the Son of Acnologia is good. Besides that, please check out "The Daily Life of a Fairy Tail Mage," and "The Ultimate Cross-Over!", the two stories that I have created so far. Hope you enjoy this story! (A.N. I just revised this. After re-reading the first chapter, I thought that it looked too chunky and… well, stupid. So I fixed it up so it doesn't look that bad anymore).

Year 412
"I will give you a deal, Acnologia." Zeref sneered. The man to whom Zeref was talking looked up, giving him a glare. The two men were located on a desolate mountain in the middle of a barren desert. It was usually loud, with small desert animals crawling around and doing their business. Now, it was utterly silent, for these animals sensed danger that radiated from these two men. Acnologia had long, ruffled, light blue hair and a tan, muscular body. His eyes were devoid of any love or kindness. He was wearing a long, black cloak, no shirt and black baggy pants.

"I'm listening." Acnologia said before he spat at Zeref's brown moccasins. Zeref's red eyes began glowing, but ignored Acnologia's insult as much as he could. Zeref was wearing his black cloak that was wrapped around him, along with a long white scarf that was tied from his shoulder to the right side of his stomach. His black hair was swaying in a breeze that went passing by
"I will give you power," Zeref began, "Unimaginable to any man or woman. A power so deadly that dragons and gods will tremble in fear if mentioned. You will herald this power, and become a god." Acnologia leaned back against a rock, thinking.
"What's the price?" Acnologia asked. Zeref smirked.

"The price? The price is that once you take this power, you will become a dragon."
"Heh, that's not so bad," Acnologia remarked, "But I have a feeling there's still more."
"Of course there is. Once you gain the power, you must begin hunting down dragons to become stronger." Acnologia snorted, raising an eyebrow.
"Zeref, that's not a price, it's pretty much a reward-"
"I'm not finished." Zeref cut off Acnologia with an icy tone. Acnologia growled, but listened anyways. Zeref furrowed his eyes, staring at the sky in wonder. For a few minutes, both were silent, as desert tumbleweeds floated around them.

Finally, Zeref said, "In 350 years, a boy- one whose hair is pink, will find you."
"You want me to eat him?"
"No," Zeref smiled maliciously, "I want you to train him." An awkward moment of silence enveloped the two. Acnologia coughed nervously.
"Zeref," Acnologia replied, "I'm- err- not what you would call a 'fatherly figure.'"
"I don't need you to be a 'fatherly figure', I need you to train him. Nothing more, nothing less." Zeref drawled, looking at his nails.
"Why do I need to train him?"
"It is none of your concern." Acnologia grunted.
"And if I do not train him?"
"Then I will kill you. Painfully." Acnologia sighed while scratching his head. Another awkward moment of silence ensued. Acnologia, after a few minutes, looked up at Zeref with his green eyes.
"Fine."

Year 766 - 354 years later
"What to do…" Acnologia hummed before gritting his teeth in pain as his lower left limb felt like it was dipped in lava.
"Stupid fire lizard," The Chaos Dragon murmured, hopping to his feet, and dragged himself out of the giant cave he was in, "He was a tough one, I had to admit. Good thing I killed him before he could've done far more damage. Damn that Igneel…" Acnologia spread his wings as he looked down at his domain, relishing for a lake big enough to cool down his throbbing leg. Acnologia finally pinpointed where a lake that size was and flapped his mighty wings, taking off to the sky. When his leg was finally starting to cool down because of the clouds, he dived down to the lake, head first. He shot through the water like a torpedo, creating a huge splash.

"AHH," Acnologia sighed as his leg began to feel again, "Much better- so much better." Acnologia dove straight into the water, watching a fish regarding him with wide eyes.
"Scram." Acnologia hissed through the water, as the fish scurried away in apparent terror. Acnologia laughed loudly, causing the rest of the creatures that lived near the lake to flee in fear. Acnologia enjoyed the coolness of the water for such a long time that he did not know that it was getting very late. Before Acnologia knew it, the sun began to set rapidly. Acnologia looked to the sky and sighed, cracking his neck in the water.

As Acnologia got up from the water, he noticed a few rather large wyverns stalking up the lake, looking pretty full. Acnologia regarded them quietly, before grinning like a mania.
"Hunting time~"

A few traumatizing scenes later
"Alright, I'm calling it a day." Acnologia flew up into the sky again, carrying the limp bodies of the flayed wyverns in his claws. He zoomed to a giant and intimidating mountain that overshadowed the landscape. Acnologia spread his wings further as he spiraled to the peak of the mountain, where at the peak there laid a cave entrance. Acnologia landed roughly into the cavern, hissing again as the wound that Igneel made began to burn yet again.

Fuming, the Chaos Dragon flung the wyverns to the side of the wall, before ripping into one of them.
"It would be nice if I could actually cook these skins," Acnologia hissed as he ate the wyverns like how a human would eat a chicken leg, "But, even if I could transform into my human form, I doubt I could cook these pieces of meat." After eating all of them, with strings of meat lying here and there, Acnologia yawned. He headed towards his makeshift bed of lambskin and collapsed there.

Acnologia, turned onto his back and stared at the ceiling, where a few drops of water landed on his face.
"So I defeated and killed Igneel." Acnologia thought. "Now, there are no more dragons worth my attention… Bah, tomorrow," Acnologia started to close his eyes in exhaustion, "Maybe I should hunt down that dragon Metalicana, just for training."

Two Hours Later
Acnologia heard some ripping noises that echoed in the cavern as he slowly began to wake up.
"The hell is that?" He thought, before slightly opening his eyes to peek around the room. He was surprised to find a small, three year old male who was nude and had pink hair gobbling up the remains of last night's wyvern dinner. Acnologia watched in amazement as the boy ripped off a huge chunk of meat and began chewing it like a crazed animal. Acnologia shook his head, slowly getting a little pissed.

"WHAT ARE YOU DOING HERE?!" Acnologia roared. The boy stopped and stared at the dragon in awe (not horror), before trying to talk, accidently spitting out chewed-up pieces of meat. The Chaos Dragon wrinkled his nose in disgust.
"DON'T TALK WITH YOUR MOUTH FULL, BOY!" The boy obediently swallowed the remains of his wyvern meat.
"Well," the boy replied innocently, "Yesterday, I climbed on your back-"
"WHY?!"
"B-because I thought it would be fun?" The boy's eyes started to swell up in tears.
"Oh boy- err, kid, don't cry." Acnologia mumbled as the boy started to cry, "Please-err- continue your story."
"O-ok," the boy sniffled, "You were flying around, and it was fun. You didn't notice that I was on your back, so I thought it was OK to keep on staying on your back. Then you flew into this cave, and you began snacking on the crocodiles-"
"Crocodiles?" Acnologia thought, "He obviously meant wyverns-"
"- So I began snacking on the crocodiles, too." The boy finished. Acnologia grunted.

"Do you know who I am?" Acnologia asked. The boy looked at the dragon long and hard. Acnologia swore he saw steam coming out of the boy's head.
"… YOU'RE A BIG LIZARD!" Acnologia nearly face palmed.
"I'm Acnologia, King of the-! OW! WHAT THE-?!" Acnologia snarled as he saw the little kid poking at his throbbing wound.
"Does that hurt, Mr. Acnologia?" the kid asked innocently. "Do you want me to-"
"YOU STUPID TWAT!" Acnologia roared, startling the young boy. "DON'T TOUCH ME THERE! YOU LITTLE-" Acnologia raised his paw to strike the boy down for his stupidity.

"In 350 years, a boy- one whose hair is pink, will find you."
"You want me to eat him?"
"No," Zeref smiled maliciously, "I want you to train him."
Acnologia froze and stared at the little boy, who only blinked in wonder.
"Are you kidding me?" Acnologia growled, "This stupid, pink-haired, skinny boy? I have to train HIM?!" Acnologia angrily stomped out of the cave, before howling at the night sky in pure hatred.
"ZEREF, YOU STUPID MOTHERFU-"

Somewhere…

Zeref smirked.
"Finally. My plan is now set in motion."
