I don't own Fairy Tail or Percy Jackson, all of the characters except for the Oc's i have created belong to their respected creators

A/N: when i was reading through the fan-fictions of Fairy Tail i noticed that there was hardly any about Natsu joining Sabertooth or Natsu being paired with Ultear or Minerva. i decided to combine the two and create my own Fanfic so please enjoy and review if you think anything needs improvement. also in this fic Jiemma will be a bit nicer but only towards Natsu and those who Natsu sees as his family

Chapter 1- Betrayal and an offer

The whole town was burning down, ghostly white flames engulfed the streets, burning away the buildings that held family heirlooms, screams of citizens were heard as they ran for their life, smoke polluted the sky, blocking the moons rays of light from touching the ground.

The white flames seemed to move to the side allowing the beast that caused so much destruction to make its appearance. The beast was enormous, bigger than any dragon recorded, its scales were pitch black that seemed to glow icy blue in between them, the beast eyes were slit and blood red that made anything want to curl up and hide away.

The beast had a pair of large wings that were larger than those that belonged to the monster known as Acnologia, a large spiked sail ran down its back, starting from its neck and ending at its tail which was club and filled with spikes that destroyed whatever was in its path. The beasts fangs were bigger than daggers, its claws bigger than sword, each appearing sharper than any weapons forged in the kingdom of Fiore.

Finally ghostly white flames spewed out from the beasts mouth, falling to the ground and turning anything they touched to ash, the beast stopped in its tracks and looked at one spot that was illuminated by the flames showing a lone figure standing valiantly in the destruction, the beasts eyes locked onto the figure as if they were an insect that needed to be squashed.

The lone figure appeared as a male, looking to be in his twenties, his hair was cut short and spiky whilst oddly colored salmon pink although streaks of grey hair appeared within. The man's left eye was onyx black however his right eye was icy blue that appeared devilish and was slit like the beasts before him.

The man wore a pair of black cargo pants although the bottom half of the clothes seemed to have been burned and ripped away, covering his chest was a skin tight, sleeveless black muscle shirt that had a dragon logo on the left peck.

Firmly gripped in the man's right hand was a large two handed sword, the blade was gleaming silver whilst the handle was a mix between gold and silver, however the man's entire left arm looked to have been ripped off, a small magic circle was placed over the wound stopping the blood from flowing out like a river, finally a dark red symbol was imprinted on his right shoulder appearing as a Sabertooth tiger.

"The beast's names is Lucifer, the dragon of the pit and the demon of the sky and destruction. You will be in the biggest fight for your life Natsu" the voice of the man's oldest and most trusted friend spoke through his mind making the man now named Natsu smirk

"Fight for my life hay, you weren't so tough were yer. Well no more games now is it" Natsu said towards the beast who roared in reply making his smirk grow. Raising the large sword high in the sky, Natsu charged at the beast, running into the flames valiantly.

The beast roared at him and met his charge, Natsu let out a loud battle cry before the ghostly white flames engulfed the area, blocking the fight from view.

(Four Year Earlier)

It was a normal day in Fairy Tail, well if you could consider the drinking, brawling and overall chaos normal. The fire dragon slayer Natsu Dragneel had just started another brawl with his rival Gray Fullbuster and expected the day to go on like an ordinary day. However this day would be one day that Natsu would never forgot as he punched Gray in the face, causing him to stumble back into Erza Scarlet who was just about to eat her strawberry cake.

Instantly glaring at the ice wizard for disturbing her, out of fear, Gray quickly pointed towards Natsu causing Erza's glare to point at him and make the dragon slayer freeze up.

"I can't believe you Natsu, why can't for once in your life behave like a normal person and not create fights" Erza growled out as she stormed her way towards Natsu who was frozen in fear, however a loud yell from Master Makarov stopped everyone in their tracks

"Natsu!" everyone looked towards the master of Fairy Tail as he glared down at Natsu "pray tell me why you thought it was a good idea for you to burn down an entire port, three luxury houses and a museum that held sacred artifacts that predated this era. I have half a mind to suspend you from missions for a whole month for the damage bills I've been given"

Everyone was silent, they have never heard the master so angry nor have they ever heard him threaten on of the guild members by suspending them from missions, however it would only get worse when a snort of laughter was heard from Gray

"Haha. Oi Gramps you should suspend him from even entering the guild, that way it wouldn't get broken all the time" Gray laughed as Natsu suddenly started to feel cold which was hard since he was a fire mage, however before he could even get a word in others started to speak up

"Think how quiet and peaceful this guild hall would be without all the random fighting he starts as well" Macao spoke up

"We'd finally be able to drink in peace too" a drunk Cana added

"Yeah, I'd actually be able to read without fear of loud interruptions an the possibility of my books getting burned" Levy said

"Not to mention the savings we'd have from not constantly having to replace all of the things he breaks and burns whiles he's here and on missions" Wakaba answered making money signs appeared in Makarov's eyes

"All the money we'd save from him not going on missions and destroying entire cities would be enormous" Makarov added greedily

Natsu however felt sick, he couldn't believe that his friends and family would be so mean and cruel to him 'is this what they truly think'

"Our missions would go a lot smoother too along with doing a lot more good for people" Erza added making Natsu felt, anger towards her since she also destroys things but always blames him for it, Natsu now felt alone, he only felt like this when Igneel left him but it was the next person that killed Natsu the most

"The means we'd all get money from the missions too! Plus I could get better locks so I wouldn't get any unwanted visits in the middle on the night" Lucy said aloud while laughing making others laugh with her

"Well he won't be doing that when I'm there" Gray added, oh did I forgot the mention that those two started to date after their journey in Edolas, this only made Lucy grow more distant from Natsu, however the last comment made Natsu fill up with anger and hate at their betrayal

"I could also get money for fish and wouldn't have him burning them all to ash" Happy the blue exceed said as he placed himself on Lucy's shoulders, everyone was laughing as more and more people entered the conversation, mocking, insulting and betraying Natsu, even sweet Mirajane was mocking him.

"Enough!" Natsu snarled out which silenced everyone as they looked into his hate filled eyes that were had blazing infernos within them "Is that what you all think" he growled showing off his large set of fangs

"Natsu stop being so immature and take a joke" Erza basically demanded not seeing the anger within the dragon slayer as she grabbed hold of his forearm, however Erza soon felt a fire covered fist slam into her face and sent her across the guild as the heat increased causing everyone to back off and start to sweat

"I'm done, I thought this was meant to be a family but all I see are a bunch of unwanted, ungrateful bastards who's lives I saved countless times" Natsu growled as he raised his hand towards his Fairy Tail symbol and burned it away causing everyone to stare at him.

He made his way towards the entrance of the guild however stopped when his eyes locked onto Lucy's.

"I wish I never brought you here" the dragon slayer growled as he stormed out leaving the entire guild in silence which was soon interrupted by a groan from Erza and Gray speaking up

"C'mon guys this is flame brain we're talking about, he's bound to return all we have to do is wait"

It's been a week now since Natsu had left Fairy Tail, leaving his so called family behind as he ventured out, taking all of his possessions and jewels from his house before any of the Fairy Tail members could come and stop him.

He had traveled quite far since he left Fairy Tail, every day he would train, rest and then move on and on repeating the same system over and over again for the past seven years, his destructiveness grew as his reputation grew even more after scorer weekly somehow leaked about him leaving Fairy Tail.

Right now Natsu was camping out in the middle of a dark forest, a small fire lit up to give him some light as he cooked the meat he had recently hunted

"I finally found you boy" a deep, gruff voice spoke up making Natsu quickly stand up and turn around only to come across a tall, elderly male who was distinguished himself with an extremely, muscular appearance. He had long white hair and a thick beard and moustache, like his hair colour his eyes were a white making it look like he had no pupil. He wore a short and mildly loose kimono that covered the rest his entire body, he stared down at Natsu who held his standing and stared back

"You have no fear boy. Good, most of my guild members wouldn't even be able to look me in the eye" the large man spoke making Natsu frown, his time spent alone made him quite distant and allowed more negative emotions like anger and hate to build up in his body.

"Sounds like their cowards then, why were you looking for me?" Natsu asked making the old man give a small smirk

"I've heard of your power, the once great salamander of Fairy is now named the rising Phoenix the wandering mage. The reason I was looking for you boy is because I have a proposition" the old man replied making Natsu raise an eyebrow

"I'm listening"

"Currently I am the master of a rising guild name Sabertooth, I created the guild to make the skies roar… to make the earth boil and to make the seas silent, however I cannot do that when I have guild members who can't even look me in the eyes"

"My offer is this, join my guild and help me make it become number one and in return I will help you get revenge on those Fairies that mocked you?" the old man said making Natsu gain a thoughtful expression

"How?"

"Surely watching their faces crumble in sadness and despair when they realize that their once great Salamander helped a guild to grow bigger than them will be enough. I already have a daughter that is more powerful than most of those Fairies, if you joined. the guild would rise in reputation quicker"

Natsu began to think it over, to be honest when the reason he was alone out in the world was because none of the other guilds would actually hire him stating that he was too destructive, he was losing his jewels and hasn't felt the comfort of a bed in over a week

"You know of my… destructiveness don't you?"

"I have heard, but to me that only proves how powerful you are, so will you join"

"Add me to your guild then old man, I accept you offer if you want me, so what's your name and where is your guild?" Natsu asked making a small smirk come across the old man's face

"From now on you can call me Master Jiemma, as for where our guild is well you will have to wait and see" the old man now named Jiemma said as he held out his hand allowing Natsu to shake it however the only thing on Natsu's mind right now was the fact that he was looking forward to his new life as a member of Sabertooth
