Fairy Tail: The Fourth Master

Natsu stared at the head of the creature that emerged from the ground in fear, this is the first time he felt this way.

Jellal, Brain, and all other people stronger than him, none of them can compare to this creature, just its roar alone is already enough to cause his soul to tremble.

The creature moved, revealing its body in all of its glory.

It looks like an enormous white-scaled snake with length reaching up to five hundred meters, its even larger than the titan.

(A/N: My image for the Leviathan Emperor is that of Rayquaza from Pokemon, but white, and much larger)

Natsu saw Liem riding the Leviathan's head as it began to swim towards the surface.

However, before they could go up, a large wave of black-water hit him, causing Liem to fall down as the Leviathan stop moving.

Natsu slapped his cheeks and swallowed his fear, he saw Fiana and the other saints confronting the leviathan on their own.

"Damn it! This is so not me!" He 'flew' towards Liem, who is swimming back to the leviathan.

"Oh no you don't! METEORIC BURST!"

With flames covering his body, Natsu shot towards Liem with speed impossible for ordinary humans to capture.

Liem was swimming back to the Leviathan when he was hit by a powerful force that caused him to cough blood.

"Gruhgh-!?"

Liem turned his head and saw Natsu extending his arms, trying to grab the trident, however he quickly moved his hand and retreated.

But Natsu still managed to grab him,

"I'll take this back!" Natsu exclaimed as he grabbed Liem's shirt and extended his arms to take the trident away.

However, Liem turned his body and send a kneed him in this guts, causing Natsu to let go of his shirt and missed the trident.

Liem glared at Natsu and gave him a mocking smile as he waved the trident in front of him.

"Hahaha~ you lose Salamander, just accept your fate, and let me awaken the other leviathans."

However, Natsu just gave him a smirk, causing Liem to narrow his eyes as his smile disappeared from his face.

Suddenly, Natsu raised his hands and showed Liem something. Liem's eyes widened his eyes in shock as he placed his hand on his head,

There's nothing, the crown disappeared.

On Natsu's hand, was a crown, a crown that Liem was using to control the titans.

"How did you-?" He didn't know when Natsu took the crown from his head, but he thought that it should be when he kneed Natsu, "But that's impossible, I should've felt it."

"Too bad you didn't," Natsu said, then put the crown on his head,

His bidy shines as did the titan, he then 'flew' towards the titan and stoon in its head.

He slammed his palm on the head causing the titan to roar as a reddish-gold flames covered it.

"No." Liem panicked as he swim towards the leviathan's head, dodging the attacks coming from the saints.

Fiana saw Liem sitting at the head of the leviathan and her eyes narrowed,

"Where's the crown?"

"GUYS! GET BACK!"

They turned their head and saw Natsu, wearing the crown that was being used by Liem, riding on top of the titan that was running towards them.

"Oh shit! MOVE OUT THE WAY!"

The saints did not waste any more time and swim away from the path of the running titan.

"SALAMANDER!" Liem angrily roared as he pointed the trident at Natsu.

The leviathan also roared and blasts a wave of magma from its mouth. Natsu glared at Liem as the titan raised its hand, and a large wall made of rocks blocked the magna.

However, the wall did not last long and it quickly crumbled down, but the wave of magna also disappeared.

The leviathan roared as it swim towards the titan and gripped it tightly using its body.

The titan roared as it struggled to break free to no avail.

"Die, Salamander!" the leviathan opened its mouth, intending to fire a powerful breath attack.

Natsu controlled the titan to face the leviathan and prepare its own breath attack.

Natsu smirked and glared at Liem, "If you wanted to kill me so much, how about you accompany me to meet Ankserham?"

Liem narrowed his eyes but ordered the leviathan to stop its breath attack, Natsu also did the same, after all if both attack collides, the explosion will kill them.

But, the leviathan further increased the power of its hold as the titan's body began to crack.

Natsu frowned and once again slammed his palm on the head.

A powerful and hot orange flames covered the titan, it is so hot that the water seems to be useless against it.

The leviathan roared in pain as it let go of the titan. Liem also ordered it to retreat as he can feel the boiling water burning him.

The titan ran towards the leviathan and grabbed hold of its head, causing it to roar in pain.

The leviathan then used its body and slammed itself to the titan, treating its own body like a whip.

However, despite its body getting slowly destroyed, the titan did not let go of the leviathan and keep holding its head.

Natsu spotted Liem floating above the leviathan's head and glared at him. His body was covered by reddish-gold flames as he shot towards Liem.

"METEORIC BURST!!"

Natsu slammed himself at Liem with force enough to make them shot towards the surface and reach the clouds.

Liem ignore the pain in his body, as he fiercely glared at Natsu and claps his hands,

"DIE NATSU DRAGNEEL!! ASURA'S DESCENT!"

The figure of asura once again manifested behind Liem, but this time, it was made by dark-purple energy.

It attacks Natsu with all of its arms.

Natsu wanted to counter attack, but he suddenly went out of his Titanic Dragon mode and lost all the strength left in his body.

He watched as the arms comes closer and closer, but there's nothing he could do.

However, at that moment. he heard a deep, and familiar voice in his head.

'Just this once,'

As those words echoed in his mind, his body was suddenly engulfed by a dark-crimson flames that caused the arms to halt.

Natsu glared at Liem and inhaled a large amount of air, and words appeared in his mind that wants to burst out of his body,

"FIRE DRAGON KING'S ROAR!!"

...

In a place filled with magmas, lavas, and volcanoes, a large western dragon with red scales can be seen staring at a distance.

"Just this once,"

The dragon then smirked before erupting laughter.

"HAHAHA! Atta' boy, that's a nice King-like roar you showed there."

The dragon laugh for a few more minutes before returning to its slumber.
