Authors note: I do not own fairy tail

Demolition Fist

"Flame Dragons Kings Roar" Igneel yelled and hit the three dragon slayers, Natsu ate all of it and started to light his body on fire.

"We can't just beat fire with fire, You two need to do a union raid and end this!" Natsu ordered and pushed Igneels next attack away from the group.

"A union raid could take a lifetime to perfect you idiot!" Laxus retorted to Natsu.

"We'll do it in the next five minutes!" Natsu said as he jumped up in the air and hit Igneel.

"How the hell are we supposed to do that?" Gajeel asked.

"Let's just start doing what Sting and Rouge did." Laxus said as they both put one arm behind them and started to unleash their power.

"We need to do everything in sync, that means breathing, why we are doing this union raid in the first place, and our body's need to move exactly the same!" Laxus explained.

"Ok let's work on breathing together." Gajeel said as they both worked out the union raid Natsu was holding back Igneel.

"Fire Dragons Atom Melt!" Natsu called on his attack and landed it on Igneel's left eye causing serious damage to Igneel.

"Dammit boy just finish me off and stop torturing me, you can end this all in one blow." Igneel thought to himself.

The rest of fairy tail

"Master how long do you think the battle will be?" Erza asked as everyone from Magnolia sat on a hill that overlooked their neighboring town.

"I do not know Erza, but Laxus knows that whenever there's a major crisis I tend to take everyone here, so they will know where we are when they finish up." Makarov assured Erza.

"...Do you think they could lose?" Erza asked with slight fear in her voice.

"Pffhahaha! There are two dragon slayers that are s-class worthy and an actual s-class dragon slayer, of course they wouldent lose." Makarov said making Erza chuckle a little.

Back to the battle

"Damn we are losing ground pretty fast!" Natsu yelled as he was being flung around.

"Ready?" Laxus asked.

"Yeah, let's go." Gajeel said as they both got in their stance.

Okay just breathe in and out." Both Laxus and Gajeel thought, as they released the same amount of power at the exact same time, and they both thought at the same moment that this attack is to protect their guild and town, their energys both merged into one small ball, they threw their arms in front of them and called out their attack.

"Lightning Rod Fist Of The Thunder Metal Dragon!" The attack tore down some buildings and wiped out more than half of the trees in the forest, Natsu jumped in the air and started using his flames to boost himself out of the way while Igneel got caught in the wave of destruction.

"...I think we did it." Laxus said as they stared in the dust where Igneel was last seen.

"We need to find his body just to ma-" Gajeel couldent finish before the ground started shaking and from where Igneel last was he shot into the sky and started shooting fireballs at all of them.

"Dammit that was a union raid how can he still be alive?" Laxus yelled out.

The three dragon slayers were thinking of ways to beat Igneel but no body had any ideas, untill Igneel stayed in one spot in the sky and started to charge something up.

"Oh no." Natsu said as he looked up in defeat.

"What's he doing?" Gajeel asked.

"If he gets that attack to go off then this entire town will become a giant crater." Natsu said.

"How do we beat him? He just took a union raid and is still flying like its nothing." Laxus said.

"I have one move, but it's extremely deadly to anyone caught in the radius, you two may need to run." Natsu said as he turned around.

"Are you talking about using a forbidden attack?" Gajeel asked.

"Yes, but this one consumes almost anything it touches, so you two need to get far away from here." Natsu ordered.

"I thought the plan was stopping him from destroying the town." Gajeel said.

"I can make it to where the attack only destroys living things, but that means I will take some damage as well." Natsu said.

"Ok, we will get you when it's finished." Laxus said as they both started to run across town, well Gajeel was running while Laxus used his lightning magic to skip across it.

"Ok Igneel time to use it." Natsu said as he punched his open hand.

*flashback*

"Natsu get up, today's a very important lesson." Igneel said as he pushed on the sleeping boy.

"Can we please do this later?" Natsu asked.

"No this move is a forbidden move so it will take all day to learn a fragment of it." Igneel said catching Natsu's curiosity.

"If it's forbidden then why am I learning it?" Natsu asked.

"Because forbidden means to never use it unless it's absolutely necessary." Igneel stated.

"Then it's not forbidden, just a really dangerous attack." Natsu said making Igneel get a little tick mark.

"Just get up so I can teach you this." Igneel said walking to their training grounds.

*flashback end*

"God this is gonna suck." Natsu predicted in his head as he flew up towards Igneel who was still charging up his attack.

"Igneel this is the final time im gonna try to snap you out of it!" Natsu said as furiously smacked at the dragon telling him to wake up. "Dammit! Just come back!" Natsu said, as he got no answer he sucked up his emotions and started the attack.

"Dragon Slayer Forbidden Art: Demolition Fist Of The Flame Dragon King!" Natsu punched down on Igneels head and they both were consumed by the light and so was about half of the town, both Gajeel and Laxus were fine but as they kept watching when the light died down they saw the two fall, and rushed in to see how badly hurt Natsu was.

"Damn I think Natsu actually did it." Laxus said as he watched Igneel fall down without any movement at all.

"You never know maybe he just stunned Igneel." Gajeel said as they reached the body's and found Natsu face down in the dirt, while Igneel laid next to him on his back, no more black eyes they were normal which means Natsu had finally won.

Back inside the tree

Master, Igneel has perished, what can we do now?" The old butler asked.

"This is perfect, everything is going the way it should be." The man said with a devilish laugh.

"Well since it's over do you wish to take a walk around the island? The butler asked.

"Yes this does seem like it will sort itself out, why not have a little break." The man said walking out the hole that lead onto the island. "Ahh Tenrou island, the only home I've known." The man thought as he went on his walk.
