Chapter 31:

"MINA! I'M HOME!" they all heard Gildarts 2.0. shouted as soon as he opened the doors with big boom.

"Hi, Gildarts. So how did the job go?" Lisanna asked walking toward him.

"Oh, hi Lisa. It was really easy. I don't think it needed to even be S-class request." Gildarts 2.0. said smiling. Then a flaming punch fly toward him trying to punch him in face but Gildarts 2.0. just sidestepped.

"COME ON GILDARTS! FIGHT ME!" Natsu 2.0. yelled.

Gildarts 2.0. laughed and said "Not now Natsu."

"Oh come on!" Natsu 2.0. moaned. And after that he tried to hit him again but this time Gildarts 2.0. send him flying trough the roof.

Gildarts 2.0. rubbed his forehead and then he said in unison with someone "That blockhead..."

Gildarts 2.0. turned so fast that if you blinked you would missed it. 'That voice!' he thought and when he turned he saw Natsu sitting at the bar looking toward the new-made hole in roof. His jaw fell on to the floor as he saw Natsu all in black.

"Natsu? B-but I just kick you out trough the roof!" he yelled.

Natsu looked at him with his emotionless face and cold dragon-like eyes. Gildarts 2.0. shivered when he saw his eyes but what really shocked him was the boy's aura. It was so dark and powerful and... it screamed 'death'. He needed all his will power not to take the step back. And for some reason the aura seemed awfully familiar.

Before Gildarts 2.0. could say anything else Makarov 2.0. came to him and explained to him that Natus and others from his universe were from parallel universe from which Lisanna came from.

And at the end he added "Oh, and I almost forgot to tell you. Natsu here" he said pointing at Natsu "is Chaos dragon, son of Acnologia."

At that Gildarts 2.0. paled and he could immediately remember from were was his aura so familiar. It's almost the same as Acnologia's. Then he remembered what master Makarov 2.0. just said.

"How do you mean Chaos dragon, shouldn't it be dragon slayer?" Gildarts 2.0. said confused.

Makarov 2.0 chuckled because he asked almost the same question. "No I didn't say anything wrong. He's a real dragon. He turned into a dragon almost two months ago."

Gildarts 2.0. just stare at him for few seconds trying to process what his master just told him.

"HE'S A DRAGON?!" Gildarts 2.0 shouted after few minute of silence. At that all six (Natsu 2.0. who got back inside the guild, Wendy 2.0, Gajeel 2.0. and Natsu, Wendy and Gajeel) dragon slayers covered their ears.

"NOT SO LOUD!" They all shouted in union.

Gildarts 2.0 smiled stupidly "Oh, right. Sorry"

They sighed. Gildarts 2.0. turned serious then and walked toward Natsu who was now had his back turned to Gildarts 2.0. drinking his drink.

Everyone in the room start whispered as they watch their ace walking toward pink haired dragon.

"Ahem" Gildarts 2.0. said getting Natsu's attention.

"Need something?" Natsu asked raising an eyebrow.

"Fight me" Gildarts 2.0 said and now all went quiet.

After minute of silence Natsu chuckled. "Why would I do something like that?"

Gildarts 2.0 then show him his missing leg and arm that were just like the ones from Gildarts 2.0. "I want to see if you have right to call yourself son of the monster that did this to me"

Wendy, Gajeel, Erza, Gray, Lucy and cats paled.

"He didn't!" Erza whispered

"Please say me he didn't just said that" Wendy said shaking.

"He did. I fell sorry for the man" Gajeel said.

They all know that Natsu don't take well when someone call him 'monster' but if you called his father a monster... better run. Run as far as you can and don't look back.

Natsu rose up from his seat looking Gildarts 2.0. straight in eyes as his magic surrounded him. When he fully stood up he disappeared. Everyone watch with wide eyes as he reappeared right in front of Gildarts 2.0. and punch him in stomach. The punch trow Gildarts 2.0. across the guild hall and right trough the wall as he landed on beach where Natsu and his counterpart fought earlier that day.

"You wanna fight. The fight will you get!" Natsu growled at Gildarts 2.0. who was now sitting in the middle of the beach getting up. When he get up he got in fighting stance and looked at Natsu who was still surrounded by his black and red energy.

Gildarts smirked and said "I didn't expect that you could punch so hard. I'm impressed kid"

Everyone were by now outside again and Wendy 2.0. whispered to her counterpart "Why I have feeling that Gildarts just made huge mistake"

"You don't have any idea how right you are" Wendy said to her counterpart who frowned.

"This won't end up good" Wendy 2.0. said and Wendy nodded.

"You know Gildarts. I don't take well when people call me a monster... But if someone even dared to call my father a monster... I torture them... oh, and don't worry I won't kill you. I didn't kill them either. They done it themselves." Natsu finished with wicked grin and everyone gasped when they heard Natsu's voice at the end started to turn demonic until it become completely. Next they heard was sound of tearing flesh and breaking bones. It was so awful that someone covered they ears but it seemed like sound found his way in their heads and wasn't about to leave. Those one that still watched at Natsu (namely those from his universe, Wendy 2.0., Natsu 2.0., Makarov 2.0., Gajeel 2.0., Erza 2.0., Gray 2.0., Lucy 2.0., cats 2.0. and Gildarts) watched, some in pure horror, some in fear, some even in awe and some all of that, as on Natsu's back the skin was being teared off of his flesh and slowly the flesh tear off of his bones as two large wings slowly grow on his back tearing and breaking every bone and piece of flesh on their way. Then his skull was changing its shape as well as two large black horns grow on it. Behind him start swinging black scaled tail with red markings. On his arms and chest formed scales as well as around his eyes. His legs looked like hind legs of the dragon as he stood now only on his front part of his foot.

"Ready to play, Gildarts?" Natsu said in demonic voice licking his lips like as when a predator looks at his prey. Wicked smile never leaving his lips.

Everyone around him were now scared shitless. Makarov 2.0. watched at boy wide-eyed. 'How can his body hold so much magic power. His body should fall apart by now from that insane magical energy. Oh, Gildarts, you fool now you too will be in a world of pain.' Makarov 2.0. thought worried for the safety of his child.

He didn't think Gildarts 2.0. was weak but this Natsu... Makarov 2.0. wasn't so sure he could defeat him himself.

Gildarts 2.0. was on other hand in the same time awed at boy's strength and magical power as well as scared because it resembled so much to the power of his father.

"I'm ready when you are" Gildarts 2.0. said with smirk.

In the next second Natsu appeared behind Gildarts 2.0. and whispered in his ear "You're blood smell delicious"

Makarov was the only one that was able to see him and he barely did. Gildarts 2.0. shivered as well as other dragon slayers that heard him.

"He's crazy" Gajeel 2.0. said to Gray who nodded.

And then Natsu hit him in back and sent him flying. Gildarts 2.0. spun in air and somehow landed on his feet. He stretched out his right hand and shoot his crash magic at Natsu who easily dodge the attack and start running toward him in inhuman speed but this time he let himself been seen.

He lit his fist on with his magic and yelled "Chaos dragon's Iron fist!"

Gildarts 2.0. in last second barely dodged the attack and yelled "Crushing Evil, Spreading the Truth: Empyrean!"

He was able to hit Natsu with the spell and powerful uppercut sending him crashing in ground much to everyone's surprise.

"Well that was an easy fight" Gildarts 2.0. said smiling looking at crater that Natsu made when he hit the ground. He couldn't see Natsu because it was engulfed with smoke.

'Don't be so stupid Gildarts. He won't go down that easily' Makarov 2.0. thought.

Then just before Giladrts turned his back in smoke appeared figure. "Well that actually hurt a little. I knew you're fun to fight. How about I show you another attack of mine?"

As smoke cleared there stood Natsu with his shirt slightly tattered but there wasn't even a bruise on him. Not even a scratch.

He start building his magic. "You should feel honored. I can use this attack only in this form and not many people saw it. This is one of the demon spells combined with my chaos dragon magic."

"Dragon slayer secret art: demon lord: oblivion's fist" Natsu growled as he jumped high in air and his fist was warped in his magic energy but instead of the energy being black with red sparks around it it was red with black sparks. Gildarts 2.0. tried to dodge but wasn't fast enough to move his whole body so attack hit his left prosthetic arm. When attack collided there was large explosion and dust raised from the ground making again smoke wall so no one could see beside those two what was going on. Gildarts 2.0. flew ten meters backwards when the attack hit him and he fell on floor panting. He look at his prosthetic arm in shock because it wasn't shattered like he thought it would be. The arm slowly disintegrating and turning in ashes until the whole arm was gone leaving nothing.

He couldn't understand what happened. The attack wasn't so hot to actually burn his arm to ashes so how?!

"What on Earthland did that attack do?!" Gildarts 2.0. shouted. He looked around himself to see that smoke was clearing so now he could see others that watch the fight. When they saw him without his arm they gasped.

He looked around himself to find Natsu as he slowly got back to his feet.

"You're lucky that that attack hit only your prosthetic arm. That it hit any other part of your body you would disintegrate to ashes" They heard voice from above. Everyone's heads shoot upwards to see Natsu in the air with his wings spread. The sun was setting now and the sky looked like it was on fire. Natsu there in the sky looked even more scarier with his cold eyes and wicked grin. Real demon from nightmare.

Gildarts 2.0. finally registered what he said and shivered at the thought. 'I have to be careful not to get hit by that again' he thought.

Natsu charged again this time yelling "Chaos Dragon's Wing Attack"

His wings warped in Chaos energy and shoot the attack at Gildarts 2.0. who yelled "Crushing Evil, Spreading the Truth: Ikazuchi!"

This negate Natsu's spell and send the crash magic at Natsu who just fly to the side to avoid the attack.

Gildarts 2.0. looked at him annoyed "Come down here already!"

He didn't have to say it twice cause in next second Natsu was already in front of him hitting him with his tail right in head sending him flying.

"Ow..." Gildarts 2.0. moaned sitting up. He stood up again and now the two were in hand-to-hand combat. It seemed that they are equal in that but if you look closely you could see that Gildarts 2.0. had little trouble to keep up.

"I must say that I would have good time fighting with you if I'm in my human form. You would actually present a challenge." Natsu said smirking evilly at the struggling man.

"Then go to your normal form" Gildarts 2.0. said while avoiding another strike coming from Natsu.

"First: My normal form is my dragon form. I don't think you would like it" He said as his smile grew wider when Gildarts 2.0. paled "and second: I have to let demon play sometime"

And with that Natsu punched Gildarts 2.0. right in face but Gildarts 2.0. somehow was able to kick Natsu in stomach and both men were sent flying trough the air.

Natsu spun himself in the air and landed on his feet while Gildarts 2.0. hit the ground with his head first.

"How about I end this?" Natsu asked while watching as Gildarts 2.0. struggle to stand up barely awake.

He then started to build his magic again and after few seconds he yelled "Dragon slayer secret art: demon lord: nightmare awakened"

Claws on his hands extended a little and warbed in thin layer of chaos energy and some kind of fluid start dripping on floor as he run toward Gildarts 2.0. He starched out his hand and pierced his claws into Gildarts's 2.0. skull. Gildarts 2.0. fell on floor eyes closed. Natsu pick him on his shoulder and look around himself. He chuckled at the sight. Everyone expect Makarov 2.0., Erzas and Mira were knocked out from magical pressure that the two were emitting in fight.

Erza looked at him angrily "You killed him!"

Erza 2.0. requiped in her Heaven Wheel armor and Mira got in Satan soul. Makarov started glow in his magic energy.

Natsu chuckled again at their stupidity.

"I didn't kill him" he sad.

This caused them to calm down slightly "You pierced him right trough his skull! Of course you killed him!"

Natsu sighed and put Gildarts's 2.0. body on floor and showed them his head. There wasn't blood at all. There wasn't even wound. And now when they looked closely they could see that he was still breathing.

"See. He's alive" Natsu said.

"B-but how?" Mira asked.

"The attack I used put the target in sleep full of worse nightmare you could imagine. The fluid that was on my claws is like poison- but not deadly." He added fast when he saw them paled. "When it came in contact with blood it cause nightmares. Why isn't there even scratch is because the energy that is around my claws that close it immediately without side effects. Of course, I can remove it when ever I want to but until then he will have nightmares for the rest of his life until he go crazy because of them and kill himself so he don't need to watch it anymore."

"Will you remove it?" Makarov 2.0. asked still pale.

"When he apologize for calling my fathe... I mean Acnologia a monster I will. Until then, no" Natsu said and then looked at other that were still unconsciousness.

"Lets take them inside. Shall we?" Natsu said turning back in his human form with terrible sounds accompanying him again and others cowered their ears.

"Right" Makarov 2.0. said and used his titan magic to start carry them inside.

"Why don't you call Acnologia your father?" Makarov 2.0. asked Natsu.

Natsu looked at him surprised at his question as he put Gildarts 2.0. on his shoulder again.

"He said to me that I can call him Acnologia, Master, King or My Lord but to never call him father or dad in front of others." Natsu said picking Wendy under his arm.

"May I know why?" Makarov asked as he picked up few of his children.

"It's disrespectful" Natsu said shortly and Makarov nodded.
