A Railgun In Fairy Tail, The Diablo Saga: Book 2, Time.

The Serpent That Felt Corruption

Vrull's alien soldiers looked at Mikoto with amazement.

"Whoah!" said one of them. "This chic's crazy!! What are ya doing!? We're just here to pick up some God Ore, and you come busting in!!"

"Oh God!! She killed Korag!!" shouted another alien.

"You bastard!" said a third alien.

Korag moaned a bit from under Mikoto's foot.

"Oh, never mind, he's alive.. but still.. you bastard!!"

Mikoto frowned at Vrull's minions. "You.. aren't the brightest bunch are you?"

The little Geko girl clutched Mikoto's shirt from where Mikoto held her. "Wow? Are you the angel?"

Mikoto went pink, and her eyes turned to hearts. "Ehheh..well.. well.. I don't get why something so cute would think I'm the angel..."

Mikoto's bliss was interrupted by an explosion of red plasma energy, as Vrull burst out of the rubble from where he was thrown.

"Alright!!" Vrull roared, his pincer mouth snapped angrily. "Who dares fight against the galaxy's second most powerful warlord!! I, Vrull of the Randoracks!!!"

"Oh.. so you're still alive.." Mikoto said. "What a pity."

Vrull stared at Mikoto with astonishment. "You.. DARE!?"

"Yeah.. seriously uncreative." said Mikoto. "You dare, you dare, you dare.  You know how many guys I've fought said that to me before? Asgawrath, Diablo, Black Whisper, Hades, Charles, come to think of it.. almost all of the Espada at some point.. it's getting really old.. really really old."

"It's been ages since I've seen a human." said Vrull, licking his sharp teeth with a forked tongue. "So I'm going to explain things to you nice and simple. You see this right here?"

Vrull held up the crystal that he had taken from the little Geko girl. "This is God Ore, it is a rare substance created with a Numensapien leaves behind an ancient powerful spell. One ounce of this stuff holds enough potential clean energy to raze an entire planet over with spells of unfortold power... it's magic.. MAGIC!! and that's rare enough in the universe... these silly little cute frogs and their planet were created by a Numensapien as a birthday present for a young princess Numensapien known as Fulguras... that makes this entire place a GOLD MINE!!! And these pathetic little frogs, are our workers.. so... let go of my employee little human!!"

Mikoto scowled at Vrull. "Gekotas aren't slaves.. GEKOTAS AREN'T YOUR PETS!!!"

Mikoto set down the little Geko girl and her four wings flapped angrily, creating electrical shockwaves in the air.

Vrull laughed. "I don't know what power you possess girl.. but I possess the sacred power of my race.. the Rage!!"

Mikoto frowned. "The what?"

"The Rage!" said one of Vrull's men. "A power that very few of our race possess that grants control over the energy known as  plasma!!! We are one of the 12 sapient races that possesses one of the Powers!!"

"You see ignorant human.." said Vrull. "There are 9 great powers in the Universe. The first three. and the strongest of all powers, that the 12 races rarely receive are Magic, Death, and Mind, also known as Magic, Spirit, and Science!! Then there are the 6 lower powers. The Rage, grants powers over single elements..and is exclusive to my race.. and my element is plasma!!"

Vrull enveloped one of his fists in a red plasma energy and he launched forward, his feet propelling plasma energy to speed him forward..

Mikoto stood her ground and folded one of her wings over herself, blocking the plasma punch. There was a shockwave.. and powerful volts of electricity coursed through Vrull's body from the wing, blasting the alien back.
