Natsu:
One minute, Sophia was rushing to his rescue, the next she had passed out as a powerful attack rushed straight towards her. Natsu locked eyes with her as she fell to the ground, but he knew he couldn't make it to her in time.
"SOPHIA!" he screamed, attempting to rouse her from whatever sleep she had fallen into. He began to run towards her, but another wall of flames rose up and blocked his path. He grunted in pain as he watched the God's Bellow attack envelop the red-head. Her body was flung across the grassy field, rolling past a shell-shocked Wendy. Natsu fell to the ground, gritting his teeth and pressing his fist into the soft, wet, dirt, angrily.
"It's no use!" Zancrow called from across the expanse, sauntering towards the injured dragon slayer. "She's under Kain Hikaru's spell."
Natsu's eyes widened. That fucking doll. He growled, his extra sharp canine teeth showing. Zancrow narrowed his eyes, secretly intimidated by Natsu's change in attitude. A different aura was coming off of the pinkette; a more serious, vengeful one.
"You're going to fix her after I beat your ass into the ground," Natsu snarled.
"After this display, I can't say I'm worried," the blonde slayer retorted, flipping his hair and laughing. Natsu growled, low, in the back of his throat, and planted his feet firmly in the soft soil.
"Your flames won't work on me," the fire dragon slayer stated solemnly. He stared Zancrow straight on, feeling the single bead of sweat roll down his forehead, tickling his face, his heart rate increasing as it traced a line in the dirt on his tan skin. Zancrow began to guffaw, his lean body shaking with laughter.
"That's rich! You're too cocky, wannabe dragon slayer."
He suddenly raced forwards, slamming into Natsu, sending him flying backwards, followed by a wave of black fire searching for a victim. He smirked, leaning forwards slightly and cocked his head towards Wendy.
"Watch this, kid."
Wendy gulped, her heart rising into her throat. She felt like she was going to throw up. What could she do? She was injured (it was agony to move) and if Natsu and Sophia had been taken out so quickly, what good would she be?
"Oh! That's it!" Wendy exclaimed to herself. She began to crawl towards Sophia's body, going slow as possible to avoid Zancrow's vengeful gaze. She was stopped in her tracks by a pillar of midnight flames shooting into the clear blue sky not ten feet away from her.
"NATSU-SAN!" she screamed. She was vaguely aware of Happy zooming over her head, straight towards the magic.
"NATSU!" he yelped, his voice quivering in fear for his best friend.
"HAPPY, NO!" Carla yelled from the sidelines. "THOSE ARE FLAMES NOT EVEN THE FIRE DRAGON SLAYER CAN EAT! YOU'D BE INCINERATED!"
Happy crash landed just outside of the blast zone, rolling through the dirt.
"HAHA!" the god slayer cackled, his silhouette appearing out of the fire. "You thought you could eat the flames of a god? Flames that are above even a dragon? You're gonna end up getting divine punishment, kid."
Natsu was on the ground, beaten and bloodied. He shakily pushed himself up and looked up at the blonde mage standing over him.
"My power's on a completely different level than yours, kid. I'm a god killer. A god slayer."
"Pshht. I've felt flames hotter than these. Bring it on!" the fire dragon slayer challenged, getting to his feet and raising his fists in front of him. Natsu charged the older mage, sending a whirlwind of fiery attacks towards him, relentless in his barrage. Zancrow grinned, a malicious, cold smile.
"So this is the power of a dragon slayer?"
Natsu cocked an eyebrow as he landed hit after hit, moving Zancrow back with every hit.
"God slayer my ass! You say god taught that to you?!"
He spun and leapt through the air, landing a roundhouse towards Zancrow's chest, but the god slayer blocked it, holding his arms in front of him in an x shape.
"Since Master Hades could be considered a god...then yes. This is indeed the lost magic I received from god."
Natsu suddenly started to laugh uncontrollably, a sadistic smile crossing his face, his teeth growing sharper and more intimidating.
"SO YOU JUST LEARNED IT FROM SOME STUPID HUMAN! HAHAA!"
He shot forwards, getting inside Zancrow's defense and whispering in his ear, "I learned mine from a real dragon."
He grinned as fear flashed through Zancrow's eyes, but the exchange was too quick. Natsu punched him in the gut with a powerful fire attack and the god slayer was catapulted across the field. But the victory was short lived. The blonde righted himself in the air, landing roughly on his feet, sliding backwards through the crumbling dirt. He pulled his hands back by his side, and as Natsu began to yell, "FIRE DRAGON'S BRILLIANT FLAME!", he began to yell, "FIRE GOD'S KAGUTSUCHI!".
Dust flew up around them as the attacks met in the middle, sending the exceeds flying backwards. Wendy shielded her eyes against the excruciating light.
"The powers of gods and dragons are clashing…" she whispered. Her words were blown away by the wind, spiraling away from her and forcing her into silence as the awe of the situation settled over the young girl.
Zancrow began to giggle, Natsu began to curse. His flame was being enveloped by the infectious black fire.
"ARGHHH!" he grunted, doing his best to hold his ground, but it was no use. The black flames reached him, taking hold of him and throwing him into the ground like a rag doll.
"NATSU!" Happy called out frantically. Zancrow suddenly rounded on him, his eyes angry slits.
"You cats are really starting to piss me off," he muttered as he threw his hand to the side and the exceeds caught fire.
"FUCK OFF!" Natsu screamed, emerging from the mound of dirt he'd been flung into.
"FIRE DRAGON'S ROAR!" he yelled as his stomach expanded and the powerful attack raced towards the god slayer. Zancrow turned to face it head on, even leaning into it.
"Did you know it was god that gave humans the knowledge of fire? It was neither a human nor a dragon who created fire."
He opened his mouth and rapidly sucked in the raging fire dragon attack.
"IT WAS GOD!" he screeched at the top of his lungs.
Another bead of sweat ran down Natsu's face and he felt the fear flowing through his body intensify, weighing him down, throwing him off balance. How'd he eat my flames? My most powerful attack…
Wendy took the opportunity to crawl as fast as her hands and knees would carry her over to the incapacitated dragon slayer. She picked up her head and placed it in her lap, checking for vitals. She slapped her once, attempting to wake her up.
"You've got to learn to be less reckless, Sophia-san…" she muttered, rolling her eyes at the sleeping dragon. She laid her back down on the cool earth and prepared herself to cast troia, but Sophia's body was suddenly devoured by hungry black flames, and Wendy was thrown backwards.
"No point in wasting your magic on her!" Zancrow called from across the field. Sophia flew towards him, carried by his magic. She fell through the air towards him, but he caught her by the front of the shirt and held her close to his face, turning her left and right as he inspected her. He threw her to the ground and stepped on her back, pinning her.
"Those were some tasty flames, dragon slayer. They were wild ones, ones that'll never die out...But even if you have the strength to kill a dragon, you can't kill a god."
As he said the last words, he stepped back, preparing for a monstrous attack.
"THIS IS GRIMOIRE HEART'S MAGIC!" he cried out in glee, unleashing a destructive force of unprecedented proportion towards a defenseless Natsu.
"FIRE GOD'S BELLOW!" he roared as Natsu went sailing over the side of the cliff. Zancrow smiled smugly, releasing Sophia and slinging her over his shoulders as he trudged towards the cliff edge.
