*AN, I know the poll isn't working, so just review me your opinions, only rule is no weasleys and no voldy followers. The only review so far is ChimaTegon, so yeah.

Natsu POV

After Natsu left Wendy and the Exceeds facing off the girl whose name he knew from somewhere, not directly, but Natsu was sure he'd heard of her before. Natsu shook the shock off and went to face the scent he recognized as Zalty from Galuna island.

What Natsu found was not what he expected. Although, he never could have imagined a shapely woman caressing a black and white tuniced man, muttering senseless things.

After a short fight between the two of them that ended when Natsu was caught off guard by a large portion of his magic simply leaving him unexpectedly after a pink mark appeared on his wrist. He stumbled and the time witch caught him him a large wave of her crystal orbs, one caught him in the head and knocked him out.

Natsu was quickly shaken awake though by a frantic Happy who explained what Wendy's opponent magic was and how it affected him. Natsu was back on his feet quickly after that. He could feel fights taking place all over the island. Erza and Juvia were fighting with someone who's magic felt like is was constantly shifting. Natsu was about to sprint in that direction when he felt another magic flare.

Lisanna and Mira were up against some one way out of their league, and Natsu would be damned if he let anything happen to Lisanna, not again.

With thought in mind, Natsu dashed off towards the Tenrou tree, a fake grin and laugh plastered to his face, quickly losing Happy in the thick trees with his speed.

When he arrived at the base of the tree, Natsu was met with a grisly image. Mira was laying in a heap at the opposite edge of the grove. At least one of her arms and her legs were broken and she had several nasty burns running along her exposed stomach. Seeing his close friend in such a state made Natsu growl in anger, but that wasn't what really set him off.

Lisanna had fought bravely, but she was almost unconscious and being held up by the throat by a tall man with dreadlocks and tattoos on his face.

Natsu gave a roar of fury and punched the man in the face forcing him to drop Lisanna. Natsu caught her before she fell as he glared at the tall dark man who quickly got up.

"Ah yes, Natsu Dragneel, the fire dragon of Fairy Tail, not a true opponent, but you will do for now." the man said arrogantly to Natsu and cracked his neck. Natsu was seriously steamed now, he set the exhausted Lisanna, who had passed out, down gently next to Mira and glared at the man, letting his magic completely loose, his very aura was raising the temperature of the grove a considerable amount.

"You know what, a good friend once told me that it was ok to not take every fight seriously, but that I should always know when to use my full power, get ready, cause I'm about to hit you with everything I have!" Natsu raged at the man before leaping at him, completely surrounded by flames, unconsciously activating his firedrive.

The man was going to respond, but Natsu moved too quickly, landing another flaming fist into his jaw, following up with a knee to the gut, swept his legs, and finished with a double fist hammer punch into the ground, the mage hit the ground hard enough for a crater to form around him.

"So you are powerful, the rage of a dragon, I am Azuma, one of the Seven Kin of Purgatory, I have come in search of a worthy foe, and it appears I have found one at last, now fight me Natsu Dragneel, with everything you have!" The man leapt at Natsu and swung his arm at him.

Whatever Natsu expected his magic to be, it wasn't explosions that sent him flying back into the base of the Tenrou tree.

"My magic is the Great Tree Arc, it allows me to control the natural energy within mother nature herself!" Azuma gave a wild laugh and sent another wave of explosions at Natsu, who was more than prepared this time and dodged under and used the explosion force to launch himself at Azuma, kneeing him in the chest.

Azuma and Natsu traded blows for a while until Natsu caught Azuma off guard with a fire dragon's roar, sending Azuma flying back into the base of the Tenrou tree, his entire body scorched, but still functioning.

Azuma tore what was left of his shirt off and gave a wild laugh. "I like it, but lets see how you handle this, TOWER BURST!"

A large blast of nature energy blasted upwards around Natsu, making it impossible to dodge.

When the smoke cleared, Natsu was a little worse for wear, but he was smirking at Azuma, who was catching his breath after the large spell.

"While that technique might work against most people, I am immune to most forms of heat, all that was to me was the floor exploding, sure it did some damage, but nowhere near what it would to a normal mage. I haven't even shown you my full power and you're already out of breathe, so much for being a good fight." Natsu taunted and smirked while Azuma's crazed smile faltered slightly.

"Not good enough, let's see if this is enough to get your attention." Azuma growled and spun around to face the tree, slamming both his hands into it.

A ring of explosions triggered around the tree and it went crashing down into the ocean.

Elsewhere on the island, 3rd person POV

Gildarts wondered how he had never seen it before. He had always seen something in Cana since the first day the squirt joined the guild, yet he could never place it before now.

She reminded him of Cornelia.

Of course, defending her and her friend Luigi from a sociopath ace of a dark guild was probably not the best time to be thinking about his past heartbreaks, no time ever was really.

Gildarts landed landed several solid punches in Bluenote's gut, cutting him off from what he was going to say, sending him back into the rockface.

Gildarts went to land a finisher when a huge explosion rang through the air. He whipped around to see the great Tenrou tree exploding, falling into the ocean. As the tree fell, Gildarts felt his incredible reserves of energy fall to nothing the and Bluenote's gravity magic smashed him into the ground.

"It may be a cheap strategy, but one of the kin was tasked with destroying the great Tenrou tree, which would completely drain the magic out of everyone with the Fairy Tail guild mark. You are defenseless now Gildarts Clive, you cannot fly." Bluenote told the struggling ace, sending another wave of gravity magic at him and the two girls.

"I can still feel magic power flowing through the island, Natsu is still going, and as long as one member fights, we have a chance." Gildarts growled, feeling Natsu's power fighting someone at the great tree.

"But he is not here, and I will kill you all before he has a chance to arrive, goodbye, flightless birds." Bluenote said, extending his arms out to cast a powerful spell, but he was cut off by a blast of emerald lightning.

"You know, I thought the second ace of Grimoire Heart would be better than the first, but here you are, attacking defenseless mages with your most powerful spell, such a shame, I guess I'll have to kill you." Harry slowly walked into the rocky clearing, shocking everyone by his sudden appearance.

"You know Gildarts, you were the last person I thought I would have to save today, shape up old man." Harry told him with a small smirk before turning back to Bluenote.

"You called me the second ace of Grimoire Heart, what did you know about the first." Bluenote asked Harry

"I killed him." Harry simply answered, silencing everyone present.

"I'll tell you a story, since it is clear Hades never told you what happened." Harry taunted the stunned mage.

"The Reaper was on a mission to recover one of the keys to awaken Zeref, he was sent to a small town, and once he was there, he annihilated the town's guild and tore the city apart looking for the key.

But what he didn't know was that in this city were two small orphans, a boy and a girl, who already found the key. When the orphans realized what Reaper was after, the boy gave the girl the key and told her to run, as far and as fast as she could. The boy then took a stone off the street and taunted the Reaper with it before leading him away from the girl. While the boy knew some magic, he was completely defenseless against the Reaper, who quickly defeated him.

As Reaper prepared to kill the boy, a blonde haired man found them and showed Reaper the key, the one the girl had. The boy was crushed, but his sadness became anger and that anger allowed him to unlock a lost magic that he then used to kill the Reaper where he stood. And since that day, the boy has made it his sole goal to destroy Grimoire Heart, to erase it from the Earth." Harry told Bluenote, whose expression never changed, but Harry knew the Fairy Tail members behind him were in shock, only Laxus had ever known his story, maybe when this was all over he could rejoin the guild, as a less antisocial member, and hopefully Meredy would be accepted too, if the guild could let past Phantom members join, they would probably let Meredy in..

"I'm in a good mood today though Bluenote Stinger, practitioner of Gravity magic and ace of Grimoire Heart, so if you leave now, I'll let you go, but if not, I'll show you exactly what I showed Reaper." Harry growled, letting his aura flare, the black laced with flashes of green filling the air.

"I have finally found an opponent who can fly, I refuse to back down until my final breathe!" Bluenote said in a monotone, but Harry thought he could detect some glee hidden deep down.

Bluenote started by trying to crush Harry with extreme Gravity, but Harry covered his feet with lightning and zipped around, not letting Bluenote focus his magic. The more he wasted trying to hit Harry, the better and more effective his slayer magic would be.

"Are you so quickly reduced to running away so quickly, where is this lost magic you spoke of, where is your revenge!" Bluenote yelled, letting loose a gravity pulse in all directions, knocking Harry down, but he was quickly back on his feet.

"You can't get revenge for those still alive. She was never dead, you bastards recruited her, made her one of your kin. But you said you wanted to see my lost magic, let's see how you handle this." Harry trailed off and took a deep breathe.

"DEATH GOD'S BELLOW!" Harry let loose, sending a spiral of black magic at Bluenote, sending him flying off his feet.

The Fairy Tail members were in shock, another slayer had been in their guild all this time, and it may have been their imagination, but the gravity keeping them down lessened slightly, enough for Gildarts to rise to one knee.

"What is this, why did my magic drain when that hit me." Bluenote growled, picking himself off the ground.

"My true magic is Death god slayer magic, taught to me by the avatar of death itself. My magic drains the life force and magic out of those it hits, and once a person is completely drained, they die, thus, dubbing it death magic." Harry said to the angered Bluenote who caught Harry off guard by sending blasts of gravity at him, knocking him back.

"That would explain how you killed Reaper, he used death magic, making you the perfect counter to his magic, but I am not to be taken as lightly, where he was arrogant, I am confident, where he was weak, I am strong, where he failed, I will succeed." Bluenote said, holding Harry to a rock face with his magic. Harry couldn't use a widespread counter in fear of hitting Gildarts, Cana, or Lucy, but he still had some tricks up his sleeve.

Harry turned himself into lightning and zipped out of the way of the gravity blast Bluenote had sent at him. He tried to lead Bluenote away from the others, but when he got too far away, Bluenotes made to double back, forcing Harry to take an offensive to cut him off.

"Death God's Skull Eater!" A purple skull shaped helmet made of pure magic formed around Harry's head as he descended on Bluenote, landing a head to head collision, blasting the dark ace back.

"You'll have to better than that little bird, unless you want me to clip your wings." Bluenote growled, internally worried as he soon would be unable to cast his most powerful spell without completely draining his reserves, which would leave him wide open if he didn't take out the slayer.

"Then I will, Death God's Scythe!" Harry called and held out his hand and watched as the pure magic scythe formed in his hand. He leapt at Bluenote, letting hundreds of hours of practice with Death guide his movements.

Bluenote didn't have anything to stop the scythe so he was forced to dodge, never allowing the scythe to touch him.

Harry fought to maintain his calm, but he slowly lost his patience as Bluenote used his gravity magic to move faster while also slowing Harry down.

Harry missed on a strike, causing him to overextend, giving Bluenote the opportunity he needed.

He slammed his palms into Harry's chest and used his most powerful spell at point blank range.

"BLACK HOLE!" He yelled and a black orb of magic slammed into Harry, breaking most of his ribs and rupturing multiple organs.

Bluenote was drained, almost completely so, but the boy was laying on his back unmoving, blood trickling out of his mouth, nose, and his chest looked like it had a dent in it.

Bluenote gave a quiet sigh of relief, he had been very close to dying, and if his foe had been any older, he would have been killed.

Bluenote went to finish the job, but a pulse of raw energy shot across the island. Bluenote froze in fear, all the magic was being absorbed by the Fairy Tail marks, returning the power lost when the tree had fallen.

"How is this happening, Azuma, you weakling!" Bluenote yelled and quickly prepared himself, but after his fight with Harry, he stood no chance against Gildarts, who took Bluenote out with a single charged uppercut.

"You know kid, you are really something else." Gildarts said to the unconscious boy who had just saved his life, nearly at the price of his own.

"We have to find Wendy, Harry needs some serious healing." Cana said as Gildarts gently picked up Harry.

"Yeah, we should head towards the tree, I have a feeling that's where everyone will be after that, and I kinda want to fight Natsu now, he's been holding back." Gildarts said with a smile, starting to walk towards the tree.

"What do you mean Natsu's been holding back, he destroys so much as it is!" Lucy flipped out, yelling at Gildarts.

"Natsu doesn't like hurting people, so he hides his power, destroys stuff on purpose and pretends to be a dense idiot." Harry mumbled from Gildarts's arms, freezing everyone.

"When I get my hands on that boy I am going to wring his neck." Lucy growled, which caused both Gildarts and Cana to burst out laughing, and Harry to pull a smile across his face, despite the immense amounts of pain he was in.

Back at the tree, just after it falls

As Natsu watched the great tree fall, he felt the magic that Mira and Lisanna had left flow out of their bodies and into Azuma, who was radiating power.

"Let's up the ante then, if you manage to defeat me, I'll give the rest of your guild their power back, but if you lose, I'll use the combined power I absorbed to kill all of them, and to make things more fair, I'll only use my own power to kill you, what do you say!" Azuma said with a laugh at the fuming Natsu.

"You're going to regret threatening my friends, and you're especially going to regret hurting Lisanna." Natsu growled and launched himself at Azuma, launching him upwards with an uppercut, sending him atop the broken tree.

"I'm going to force you to use every bit of strength you have, then I'm going to kill you, but not fast enough so that you get to see me kill your precious little mate after torturing her for hours, until she's begging for death." Azuma taunted as he melded with the tree.

"You make all these threats, but I'm going to make sure you never get to follow through." Natsu growled, pulling on the great reserves within him, forcing all his power to surface. He went deeper, using his anger, his rage, his absolute desire to protect. Natsu's eyes snapped open and he said only two words.

"Dragon Force"

Natsu's power levels erupted, hitting levels he had never obtained before, even when he forced dragon force against Jellal or Zero, this was true dragonforce. Dark red scales grew along Natsu's forearms and his fingernails grew and sharpened to a point, becoming claws, a loud ripping was heard as dark red wings with a tan underside sprouted from his back, tearing his vest off. Natsu's eyes glowed a bright red and more scales formed under his eyes.

Natsu flew forward, slamming super flame charged punches into Azuma, beating him seven ways to sunday, not ever letting up and giving the crazed tree mage a chance to counter.

Azuma finally managed to get off a few explosions to take to edge off the pummeling he was receiving, but all it did was stall Natsu for a second.

Natsu let loose a roar, scorching Azuma, burning the tree away from him. Azuma started sending roots at Natsu, but as they got closer, Natsu's aura of raw fire burned them before they got too close.

"I'm going to make sure you never lay a finger on one of my friends ever again." Natsu's voice was warped by the intense fire as he bore down on Azuma.

"Ramus Sica!" Azuma yelled as he sent as many vines as he could at Natsu, making them thick enough to withstand the fire long enough to hold Natsu.

"TERRA CLAMARE!" Azuma let loose his most powerful spell is hope he would knock Natsu out of Dragon Force, making it an even fight. Azuma had realized that while he was in Dragon Force, he was practically unbeatable.

Azuma panted as he waited for the smoke to clear, to see if he had gotten lucky enough to knock out Natsu.

"RRRROOOOOOOOOOAAAAAAAAAARRRR!" The roar of a dragon echoed across the island, sending fear through the core of Azuma's being.

"You will never touch any of my friends ever again." Natsu growled as his aura grew even further, sending Azuma to his knees. Azuma could have sworn he saw an angry red dragon towering above the scaled flaming slayer.

"FIRE DRAGON'S SECRET ART, CRIMSON LOTUS EXPLODING FLAME BLADE!" Natsu yelled and threw the mass of twirling flame at Azuma, and it exploded on contact, a fiery supernova.

When the dust settled Natsu had fallen out of his dragon force and was panting heavily, years of not using his full power had made them more exhausting to use, he wouldn't be using dragon force any time soon.

Natsu saw Azuma laying on the ground laughing as his body was slowly overtaken by tree roots, branches growing out of half his face.

"You may have won this fight little dragon, but this will be the end of Fairy Tail, their magic will disperse with my death and your guild will be destroyed." Azuma laughed, but Natsu shook his head.

"I may not be the smartest guy around, but I do know magic energy doesn't just disappear. You're turning into a tree, the magic will be trapped within the tree, all I'll need to do is burn it down, you lose buddy." Natsu told him while donning his torn vest.

"You will never defeat Master Hades, and the guild's ace Bluenote, you will all die." Azuma spat before he turned completely into a tree.

Natsu quickly set fire to the tree and used his fire magic to make it explode outwards, pushing the magic back to his friends.

After that, Natsu went to the base of the tree, took a seat, and waited, holding the unconscious Lisanna in his arms.

Wendy, Erza, and Juvia were the first to arrive, carefully holding the injured master between them. Next came Elfman and the three Exceeds, carrying a badly beaten Gajeel and Levy. Last came Cana, Lucy, and Gildarts, who was holding a black haired figure Natsu first thought was Gray.

"So all we're missing is Gray the the Thunder God Tribe?" Erza asked looking over the collected people.

"Yeah, I'm gonna need your help here Wendy, Harry is unstable." Gildarts said as he laid Harry in front of Wendy, who raised an eyebrow.

"When did he get here, I don't recognize him from the guild." Wendy asked as she started to Heal Harry's ribs and organs.

"He left the guild almost right before you joined, he has some serious problems with Grimoire Heart, seeing as they destroyed his entire town before he came to Fairy Tail. He was an S-class mage and he's stronger than Erza, also, I recently learned he kept the fact he was a slayer a secret." Gildarts said as Harry's breathing became more regular.

"What do we do now, most of our best fighters are and exhausted and we don't know how many more of these guys we need to beat." Lucy complained, collapsing next to Cana.

"Well, I took out tree explosion guy, and I know I can't be the only one to win a fight." Natsu said, looking at the others.

"Loki took out another one of the kin, the goat guy, and Cana and I beat a fat sumo guy." Lucy said, getting a nod from Cana.

"Harry beat their ace." Gildarts said quietly, and everyone's eyes flew to the healing boy.

"Juvia and I defeated a man who went by the name Rustyrose." Erza said, her arms crossed.

"I got my ass kicked by crazy blonde guy, Gajeel fainted in the middle of the fight and Levy and I stood no chance against him." Elfman said dejectedly.

"I lost to a pink haired girl who was me and Harry's age." Wendy said quietly, with that comment Natsu put the pieces together in his head, but kept quiet.

"So you guys still have to beat Zancrow, the fire god slayer, and none of you mentioned Ultear Milkovich, their leader and a time wizard." Harry said, getting everyone's attention.

Harry quickly gave them a brief explanation of six of the seven kin and Bluenote, along with the heart that fueled Hades's magic.

"So we can't beat this guy until that heart is destroyed?" Erza asked and Harry nodded.

"But I already have a small scale thunder palace set up around it. While it is protected against normal attacks, thunder palace will destroy it. Someone will need to distract Hades while a second person goes to the engine room and triggers the palace." Harry explained

"So this is where you guys wandered off to." Gray said as he entered the clearing, ice covering a large gash on his side that he held gingerly.

"Good to see you alive ice princess." Natsu said, causing Gray to scowl.

"Whatever Natsu, I just beat the leader of the Seven Kin so I know I beat the best opponent." Gray countered, but Natsu laughed.

"Harry beat their ace, so he wins." Natsu laughed and pointed to Harry who Wendy was just finishing healing.

"Nice to see you beat Ultear Gray, although how you beat her I won't ask, seeing as her magic counters yours." Harry said in a voice close to monotone, but not quite, Gray gave a sheepish look in response and said something about blood.

"So what is the plan now, there are still two kin loose on the island, along with the Thunder God Tribe, and there's the matter of Hades to deal with as well." Erza asked, looking at those who could still stand.

"I'm going after the kin, the tribe is out there so they'll help me, you guys handle Hades." Harry said, getting to his feet, ignoring Wendy's protests.

"So we need to make two teams, one to hit the heart and one to attack Hades." Erza said, but Natsu shot her down.

"We still need people to protect the wounded, in case some of the kin manage to get back up." he weighed in, drawing immediate agreeal.

"I'll stay back, both my sisters are hurt, I'll be a real man and defend them." Elfman said, banging a fist into his chest.

"I'm taking on Hades." Natsu insisted, which meant of course the rest of his team wanted to go with him.

"So Team Natsu will attack Hades, the Exceeds will trigger the thunder palace and Harry will find the Thunder God Tribe and look for the two remaining kin while the rest of us defend, is everyone clear?" Gildarts asked, and when he received no disagreement, Team Natsu and the cats went towards the Grimoire Heart's airship while Harry turned and walked back into the forest, intent on finding not the Thunder God Tribe, but Meredy.

Ok, so Harry finally loses a fight, gasp. But he only just turned 14 so he can't be invincible. Nali is a side pairing in the story and I have some ideas floating around about a non crossover nali story so that may come in the future, but after I finish one of my current stories.

So I am pretty sure my poll isn't working despite trying to get it to work, so just drop a review if you want to have a say in who, if anyone, Harry and Meredy make friends with while at Hogwarts.

I also am toying with the idea of dragging Lisanna and Natsu to Hogwarts as well, but I can't find a logical reason to do that, and maybe I just drag the entire Tenrou group there, that would surely give Dumbles a heart attack, if anyone has an opinion, just leave it in a review and PM me for more in depth ideas.

I personally loved Gray's fight against Ultear and using his own blood as ice, easily his most badass fight in the series.

Happy Reading -Centurion Africanus
