Fairy Tail Super. Book 2: Black Mirror

The Ultimate Mage Warrior, Eveneel

"Let's do this.." Pumkin growled, her Super Saiyan Hakai aura exploding from her with such tremendous force, that the street began to shake.

"Yeah.." said Natsu with a grin, his Super Slayer flames doing the same thing.

"Natsu Dragneel and Pumkin Everezz.. Two of Fairy Tail's most stubborn members.." said Fused Zamasu, his voice booming across the city like that of a divine deity declaring punishment. "It is quite interesting that you would come face your doom so headstrong-like.. but I guess that should be expected.. given your natures."

Zamasu held out a hand, and a powerful blast of pure divine light, razed towards the two warrior mages.

Pumkin and Natsu nodded at each other, and both of them each thrust out a hand..

"MASENKO!!!"

"FIRE DRAGON'S BOUNDLESS RAGE!!!"

A massive surge of fire and ki exploded into Zamasu's light, blasting it aside with enough tremendous force  that it could be felt all over..

Zamasu gritted his teeth. "Such power.. so the Kais of Universe 7 truly have been training you.. that explains Erza Scarlet's new transformation as well.. Where are you Supreme Kai of Universe 7? I can sense your presence! There is no use hiding from a Supreme God!"

"Do you think he can hear us..? " whispered Elder Kai to Shin and Kibito from behind a a large boulder nearby.

"Yes, I can hear you.." said Fused Zamasu, rolling his eyes.

"Oh.. eheheh..  hi there!" said Elder Kai, waving, as Shin slapped a hand to his forehead. 

"Hmph.. such insolence! Helping mortals! You don't deserve the title of Kai!" roared Zamasu hurling his finger down, and sending a massive blast of Red energy blades from his halo. "FEEL THE BLADES OF JUDGEMENT!!!"

"OH NOOOO!!" Elder Kai screamed, falling down on his bum as the blades neared.

"VANITY DESTROYER!!!" A massive energy shockwave exploded from a golden blade, as Edo-Pumkin landed next to the Kais.

"Stand behind my blade Lords of Creation!" said Edo-Pumkin. "I shall be your steady and swift protection!"

"Oh my gosh! We have GOT to keep that girl around." said Elder Kai, grinning as he blushed pervertidly.

"Please Most esteemed Elder, you're embarrassing us.." stammered Shin. 

Suddenly, Pumkin shot into the sky, as Zamasu was occupied with the kais, her power exploding forth like a tidel wave, as she charged energy into her fist for a Savage Fist attack.

"GO TO HELLLLLLLLLL!!!!!" Pumkin roared, hurling a massive punch into Zamasu's jaw.

"KAAAAAAAPOOOOOOOOOOOOOWWWWW!!!!" The powerful attack caused Zamasu to spit out blood in surprise as he was sent flying.

"WH-WHAT!?" Zamasu roared, right as Natsu appeared behind him.

"FIRE DRAGON'S BOUNDLESS ROAAAAARRRRRRR!!!" Natsu sent out a blast of fire from his mouth.. and Zamasu was sent hurtling into the ground below..

"A-Amazing!" Erza exclaimed. "Their power, it's grown so much.. did they train together?"

"Indeed they did." said Kibito. "The most astounding progress was Natsu Dragneel. He never struck me as the type to learn to quiet his mind and control his energy.. but he's done spectacularly..  And now Pumkin has full control over her new Super Saiyan hakai form.."

Pumkin and Natsu moved as a seamless team, hurling punches and kicks, one of flame, one of ki energy, the two of them becoming blurs as they pummeled Fused Zamasu into the earth, creating a massive crater.
