Disclaimer: I don't own Fairy Tail.
The crowd was shocked at Laurus' decision to battle all seven opponents at once. However, as soon as Makarov gave the signal to start, they all began attacking him.
Laurus was calm and collected, and when Natsu tried to make the first strike, he somersaulted backwards out of the way, with perfect grace and balance. He moved swiftly and fluidly, dodging each and every attack without breaking a sweat. Lucy felt like she was seeing water whip around in a whirlpool.
Erza quickly analyzed the situation, and changed into her Heaven's Wheel Armor, to give her increased speed. She coordinated with Gray, who launched his Ice Lance to get Laurus into the range of Erza's Pentagram Sword.
"Judgement Magic: Barrier of Solemnity." he said.
An elaborately woven magic shield appeared, and Erza's blades rebounded against her. The impenetrable wall he had created absorbed the energy from Erza's attack, and threw it right back at her.
"It's time I took the offensive. Crest of the Dragon God: Seal of the Dragon Slayer!" he said.
His coat's symbols changed to an elaborate gold and silver design. The symbols were now those of dragons and swords crossed on the back of the coat.
"He can re-quip!?" Juvia exclaimed.
"This is my power. My coat changes color and design according to the magic I'm using. It's not re-quipping. This is called the Magic Gear." he said.
The crowd looked on in wonderment, as the newcomer prepared his next attack.
"Water Dragon's Roar: Flood!" he chanted.
A torrential flood emanated from his magic circle, and swept Erza and Natsu away. Gray stood his ground, being experienced with Water Magic, and Juvia joined him. Juvia began to move the water around, while Gray froze the outermost layer of the channel. This created a large dragon made of ice inside which a channel of water flowed. This Unison Raid, the Jörmungandr, was controlled by the two of them, and they directed at Laurus.
Laurus stopped the dragon in its tracks by grabbing a hold of its face, and proceed to chant: "Lightning Dragon's Roar: Pulsation."
A surge of lightning was conducted through Juvia's water, and sent her flying while being electrically shocked.
"This guy can use Dragon Slayer Magic? Moreover, two different kinds?!" Erza exclaimed.
The crowd was going berserk as the newcomer was thrashing Fairy Tail's best without even trying.
"There are many things I can do, that you haven't seen yet, Erza Scarlet." he said confidently.
"Wingbeat of the Fire Dragon!" Natsu chanted as he struck Laurus from behind, slamming him into the ground.
"Impressive. But you have yet to get me to break a sweat." Laurus said, rolling his neck as if it was nothing more than a crick.
"Judgement Magic: Edict of Extinguishment!" he chanted, and made the air reverberate, causing Natsu to suddenly collapse.
"Natsu!" Wendy screamed.
Wendy used the Sky Dragon's Roar to blow Laurus back so she could heal Natsu. However, Wendy discovered that while Natsu's magic power was intact, his Fire Dragon Slayer Magic had been temporarily negated!
"In time, the effects will fade. But very few have been able to break my Judgement Magic's hold on them. We shall see if he is one of those few." Laurus said.
"You bastard! How dare you rob him of his only weapon!" Erza screamed.
"A wizard is no warrior without a backup plan." Laurus said, as he re-quipped a katana from space. The blade was black, and had a golden hilt.
"Blade Art: Reversal of Light." he said, and his sword's colors were inverted, and he reappeared behind Erza, who suffered a severe wound, having broken a rib, and fell to the ground.
"I'll give you credit for being talented, but that is no excuse for... losing..." she said, losing consciousness.
Gajeel was the only one who remained, alongside Gray, who attempted to make a last stand, using their first Unison Raid: Frozen Steel. Pillars of steel came forth from the ground, and struck Laurus from all sides, encasing him in a frozen cage.
Suddenly, Natsu appeared in the air, and chanted: "Fire Dragon's Roar!"
Laurus, for the first time, was caught off guard, and was consumed in the flames. He arose with several burns, but they soon began to fade, as he chanted magic incantations that healed him: Sky Dragon Slayer Magic.
"Interesting. You broke free from my magic. I'm sorry, but it's time I ended this: Seal of the God Slayer!" he chanted, causing his gloves, coat and suit underneath it to become black and gold, with streaks of white on the sides.
"Wrath of the Light God: Excalibur!" he chanted.
His katana became a normal one-handed sword, and raised it up into the air, gathering light energy. He then swung underhand, unleashing a wave of energy that pushed Natsu, as he blocked it with his newest ability: Shield of the Fire Dragon.
"This test is now over! We hereby induct Laurus Acero into the ranks of Fairy Tail as an S-Class Mage!" Makarov announced.
The crowd went up in cheers, but also went to comfort the seven mages that were utterly thrashed. A few weeks later, after Natsu and the others had recovered from the fight, they went to confront Laurus.
"How many forms of magic do you know!? Seriously! I've never fought anyone like that! You have to teach me some stuff!" Natsu said excitedly.
"Tell me about yourselves, first, Dragon Slayers. I need to talk to you all in private. Come to my house for dinner tonight. It's next to Lucy's house. I also would like you to call Juvia as well." he said, before heading off.
That night, when all of them arrived at the house, they were amazed that he lived in that house all by himself. They walked in, and were dumbstruck to find it decorated like a palace.
"Do come in. I just finished making the dessert. I'll bring out dinner. I hope you enjoy pasta, soups, and salads." he said.
When they all sat down, Natsu was displeased at the lack of meat, and was almost offended by Laurus' revelation that he was a strict vegetarian.
"How do you live without meat!? It's best thing in the world!" he said.
"Think about if Lucy were to eat Taurus, the Celestial Bull Spirit. She considers him a friend, even though she herself eats beef. I imagine she would be quite distraught if she realized this contradiction. This is rather the same principle, and I have lived by it my entire life." he said.
"You called us here to discuss something, right? Get to it. I have some things I need to do." Gajeel said.
"Ah, yes. First, I would like to ask you whether you remember your parents at all." he said.
Each of them shook their heads. Even Juvia barely remembered them, despite having not been raised by a dragon.
"I suspected as much. Allow me to introduce myself in reality: I am Aquatos Draconus. I am one of the Four Gods of Creation, and creator of life." he said.
The four were more than surprised. Natsu's jaw dropped to the ground.
"But, sir, why would you lie to the guild master about your identity?" Wendy asked.
"For the reason it might alarm everyone. Or they simply wouldn't believe me, and I would need to give a demonstration of brutal force. I couldn't take that chance. Besides, my actual motivation for coming to Fairy Tail was to find you all. Being a god, naturally, I am immortal. I have married many women, but sired few children. The laws of the universe forbid such a potentially powerful being to exist outside of the realm of the gods." he said.
"What does this have to do with us, sir?" Juvia asked.
"About twenty five years ago, I was divided into six beings, sent by the God King to inspect the earth. Every millennia or so, we determine whether you humans are worth keeping around. You all passed the inspection, but during my travels on Earthland, I met six remarkable women in my different forms." he said.
"So you married all six of them!?" Natsu said.
"Yes. And for the first time in many years, I sired children. Unfortunately, six, one to each woman, were born. This deeply troubled the God King, who felt a threat to his power. Almost as a punishment for my impudence, my divine power overtook my wives, killing them during childbirth, which, to the God King, ensured the children's deaths. My heart was broken six times over, and I resolved to keep them alive, and located six dragons that were friends of mine, to take care of them in my stead. I could not stay on Earthland to care for them." Aquatos said.
"How awful! What happened to the children?" Wendy said.
"The dragons did as I had requested of them. Igneel, Metalicana, Grandeeney, Torrentia, Weisslogia, and Skiadrum; fire, iron, wind, water, light, and shadow." he said.
Everyone paused for a moment, and the foursome's eyes began to widen in realization as they heard their foster parents' names. Except for Juvia.
"I don't understand. How does this concern me? I don't remember my parents too well, but I do remember they were human." she said.
"Despite my efforts, one child was lost. This baby had been found by a childless couple, and Torrentia never found the lost child. I can tell you all understand. These lost god-children are you all." he said.
