Natsu needs training

10 years ago Natsu went out on a journey to get stronger but didn't tell anyone and left a note saying. "Don't worry ill be back someday ill miss you guys don't forget about me." When everyone saw what Natsu wrote they went out on a search for him. Makarov knowing the boy was only 11 years old was worried sick about him thinking he could die.

3 years later Somewhere in an unknown island

Natsu now age 14 was training with Atlas Flame the hell dragon Atlas was completely in fire and was teaching Natsu new techniques like Hell dragons ever burning flame, Hell dragons fist, etc Natsu looked up at Atlas Flame and said

"See how strong I have gotten in just 3 years!?" Natsu asked.

"hush up and do your training and stop goofing off I said I would help but you're making me regret agreeing to this" Atlas Flame said in a annoyed tone.

1 year later

"Natsu show me the three secret hell fire dragon slayer techniques" Atlas Flame demanded.

"Hell-bound dragons final retribution!" Natsu said to a unlucky forest in front of him as he threw open his arms as a huge gust of fire go from 3 feet to 15 feet to 30 feet and burned down half the forest.

"Hell-bound iron fist of hades" Natsu then punched a tree and split it in two as the punch landed it blew the access fire behind the tree burning the other trees as well.

"Hell-bound hole of the flaming dragon" Natsu screamed as he jumped up in the air, he threw up his hands and touched the ground in full crimson fire creating a massive hole in the ground.

"Good Natsu you've almost completed your training with me you've still got 1 more year though." Atlas Flame said

"Pssh I can take whatever you throw at me flame dragon." Natsu spat

"You're just as stubborn as your father." Atlas thought.

1 year later

"Natsu show me everything you learned!" Atlas shouted, Natsu then started to gather magic.

"Hell dragons ever burning flame!" Natsu yelled as he bursted into crimson flames and burned everything within a 10 meter radius.

"Hell dragons fist!" Natsu then punched a redwood tree that burned but still had some of it left.

"Hell dragons wing bust" He threw his arms up and threw them at the redwood tree he previously burned and he burnt it to ashes "Hell dragons roar" Natsu cuppedhis hands in a circler form around his mouth and spewed out crimson fire at three oakwood trees and burned them all down in one shot.

"Hell dragons urban flame" Natsu then put his hands together as they were both holding crimson fire balls and aimed at a pine tree that burned up in just two seconds.

"Hell dragons burning knee" as Natsu landed the knee to the tree it almost broke down 10 other trees behind it.

"Hell dragons crushing fang" Natsu then lit his hand in crimson fire then swiped at a tree in a claw like fashion burning the tree and leaving a nasty scar.

"Hell dragons axe horn" Natsu then jumped up in the air pushing his body backwards then lurching forward in a axe like motion splitting a tree in half.

"Good Natsu you've showed me the basic fighting moves and showed me you could do all three secret arts last year now for the final test."

Atlas then proceeded to engulf Natsu in crimson fire that Natsu ate and became in dragon force.

"show me the one move that is unstoppable." Atlas demanded.

"Hidden Hell Form-White Fire: Phoenix Sword!" Natsu was then covered in white fire and thrusted himself sideways and threw white fire that took shape of a tsunami and burned all of the forest that remained.

"Natsu you have completed your training with me theres only six including you that can take on two dragons inside of you but i think you need more training" Atlas said.

"But I need to get back to the guild they probably think im dead by now." Natsu said trying to explain to Atlas.

"Boy do you know when dragon slayers stop learning magic?" Atlas asked.

"No" Natsu replied.

"At age 21 dragon slayers may not proceed to learn dragon slaying techniques if they tried they would die." Atlas told Natsu.

"But why don't people just train before they are 21?" Asked a confused Natsu.

"like I said very rare people can be taught by two dragons, but i believe you can take on THREE!" Atlas shouted.

"But I don't know another dragon that would be willing to help me." Natsu said.

"I have a good old friend his name is Zu that I think will help you on this training journey of yours, do you accept?" Atlas asked Natsu.

"What is the dragons magic?" Natsu asked.

"I was hoping you would ask that." Atlas said

Back at fairy tail

Erza was sitting at the bar talking to Mirajane, Gray was talking to Elfman, and Makarov was sitting on the bar thinking to himself.

"Master whats wrong?" Asked a concerned Erza.

"I was just thinking about HIM." Makarov said.

"Master we all agreed that Natsu is not coming back we looked for five years and nothing came up." Said Erza with tears in her eyes.

"I know that but something tells me he is still out there." Said Makarov.

"If he is I hope he is ok." Said Erza with a little bit of tears in her eyes.

5 years later

Natsu now age 21 (don't worry ill show his new powers and what he experienced while with Zu) he was standing at the bay of magnolia looking at the train station.

"I hope they are not to mad at me." Said a worried Natsu. He was wearing his normal attire ( by the way he is a bit buffer looking and taller than he is in both manga/anime.) while walking through magnolia he was surprised by a blue flying talking cat his old friend happy.

"Hey happy you mis-" that was all he could say before getting tackled by happy.

"NATSU WHY DID YOU LEAVE ALL OF US WE LOOKED FOR YOU FOR YEARS NOW YOU SHOW UP WHERE WERE YOU!?" Screamed a happy but angry cat.

"I trained with two more dragons and i had to get stronger happy but im back and i wont leave this time i promise." He said as he hugged his old best friend.

"Now lets go get you some fish." Natsu said.

"But what about the guild?" Asked happy.

"We will go see them kick the living shit out of me in a minute but lets get something to eat for old times sake." Natsu suggested.

as they finished eating they started walking towards the guild but bumped into a blonde mage around Natsus age. She introduced herself as Lucy Heartfelia

"Sorry for bumping into you i'm on my way to join fairy tail." Lucy said.

"Don't be sorry but I am a mage of that guild but I don't know if they will accept me back after I left for ten years." Natsu told her.

"WHAAAAT YOU LEFT THE GUILD FOR TEN YEARS FOR WHAT?" Yelled Lucy.

"I needed to get stronger but I hope they don't kick me out so lets get going." Said Natsu while giving Lucy a smile but she could tell he was nervous because he was sweating like crazy.

Inside of fairy tail

Nobody was talking that much, Mirajane was sweeping the bar down, Erza was eating cake, Romeo was talking to his dad and Wakaba, while Gray was talking to Cana while undressing himself by accident. while all this happened out of nowhere the guild doors open.
