Equestria's Corruption

Twilight's POV------------------------------------------------------------

Twilight was pacing in her library with Pinkie, Rarity and Fluttershy, waiting for Applejack and the others to arrive.

"Has this thing really killed over fifty ponies so far?" Rarity asked, amazed and repulsed.

"Fifty and counting, excluding guards sent to stop it," Twilight said, her voice shaking with fear. Suddenly the door burst open, Dennis rushing in, Applejack and Rainbow Dash close behind, and everything exploded into confusion. As the door opened a flash of bright light engulfed the room and Princess Celestia was hovering in the air, a look of anger, fear, and determination on her face.

"Who Summoned It?" Celestia asked.

" I don't know who would be stupid enough to try," Dennis said. Twilight had to admit, while Dennis was impulsive, and could be downright stupid at times, he was extremely brave. Alot of other ponies would have quailed under the look that Celestia had on, but he acted as if it wasn't there at all.

"Girls grab your elements and head to the Everfree Forest, thats where the monster is rampaging," she commanded. Each element was given to their respective bearer and they headed off.

"Im going too," Dennis said and grabbed his utility belt with his magic and put it on. He ran after them.

Twilight was extremely nervous. She didn't know what to expect or what it could do. Dennis must have noticed because he said "Don't worry, the Eye of Cthulhu isn't really that tough," But Twilight could see the fear in his eyes, even if it was faint. They reached the Everfree forest and arrived at a small clearing.

Twilight felt an evil presence watching her...

A twig snapped.

"Everypony scatter!" Dennis yelled. Twilight moved just in time as a large object barreled through the trees and roared.

The eye had small trails of flesh behind it, flying around like some of Pinkie's party streamers. The eye was bloodshot with a large blue iris and a black pupil. In short, it was really ugly. Dennis unsheathed his sword and rushed the monster; The eye's pupil enlarged as a smaller version of it flew out. Dennis sliced it in half and it sprayed him with blood. "Well what are you guys waiting for, an invitation?" Dennis asked as he dodged the eye's charges. Twilight used her wings to fly up in the air, and released a beam of energy that hit the monster and diverted its attention to Twilight. It charged and Twilight dodged and led it to a rocketing Rainbow Dash who kicked it right it's pupil.

"Did you see that, ugly?" She gloated, "That was somepony awesome kicking you right in your face!" She continued.

"Rainbow move before it-" but Dennis never got to finish his sentence as the eye charged at her and hit her, sending Rainbow Dash flying at the ground. She hit with a sickening crack and moaned in pain. Twilight fired three consecutive blasts at the monster, and all three hit. Twilight could see Dennis concentrating hard and saw him fire five spinning purple curved blades at the monster they all hit and the eye charged at Dennis and smashed into him like a freight train, sending him crashing through a tree. Twilight looked to see Rarity with four large and sharp gems hovering around her.

"Take this you uncouth beast!" she shouted and sent them rocketing towards the Eye of Cthulhu. This time only 2 hit their mark, lodged deep into the large eye's body. Applejack was circling it and taking out the small minions it spawned, bucking each and turning her hind legs a brilliant shade of red.

"Pinkie, distract it!" Dennis said, and Pinkie Pie pulled, from what seemed out of nowhere, her party cannon and fired it, sending a colorful assortment of streamers into the air.

The Eye of Cthulhu looked at her for a moment

It was all they needed.

Twilight unleashed another beam of energy and Dennis jumped and hooked onto the beast with his sword and slid down, making a horrible squelching noise as he slid. Dennis fell to the ground covered in blood, but grinning all the same. His face lit up with a happy smile that said they won but then turned to an expression of absolute horror. "Second stage..." he said. Twilight grasped it faster than anypony else.

A huge roar sounded and the monster charged Dennis and Twilight. The sound of hind legs snapping sounded as Twilight and Dennis were sent flying. Pain instantly wracked Twilight as she saw that both hers and Dennis' hind legs were bent at odd angles, jagged bone poking through their flesh. Dennis was still trying to fight as he sent glowing spheres of water towards the monster. The Eye of Cthulhu had changed, it had shed it's iris and in its place was a huge mouth with large uneven teeth that were stained with blood. It charged faster and was more powerful than before. "Its stronger but cant summon anymore of the small eyes and has a lower defense!" he yelled desperately trying to give her friends an advantage. "Twilight, they cant defeat them on their own," He said through gritted teeth. "I don't know what the Elements of Harmony are, but you have to try to use them," he said, levitating a bottle full of pink liquid towards her. "Drink this," he said, almost seconds away from passing out from pain. Twilight took a sip from the bottle. It was sweet and tasty, like a liquid sugar, and filled her with a warm feeling. She felt her wounds closing and her hind legs were starting to heal, the pain ebbing away, and the bone slowly reforming, the flesh scabbing and healing in a matter of seconds. Twilight got up.  "Girls we have to use the Elements!" she yelled. Twilight and her friends assembled and Twilight immediately felt the power of the Elements seep through her. The necklaces on her friends were glowing and each emitting an image of their Cutie Marks from the gems. A rainbow slowly snaked its way around Twilight and her friends and finally united with the gem In Twilight's tiara. The tiara radiated with energy and Twilight's eyes became a bright white color. A rainbow erupted out of Twilight's element and hit the eye spot on, engulfing it in a rainbow of pure energy.

It wasn't working.

"Not weak enough!" Twilight had just barely heard what Dennis had said over the blood pounding in her ears. Dennis had drank some potion too and had gotten up and was entranced by the Element's display of power. He levitated his sword and did something any rational pony never would have dreamed of.

He charged.
