Rise of Evil

Summary: What if Merlin really was evil? What if she was the traitor amongst the Seven Deadly Sins? What would happen if during her battle with Grayroad her suppressed demonic powers were unleashed?

A/N: Completely AU from the point of where she shows up to fight Grayroad. No trigger warnings apply for this story. Enjoy :)

Chapter One:

Giant ice sculptures seemed to rip through the earth itself as they froze the residents of the castle in their eggs, preventing them from hatching or hitting the ground.

The two present Ten Commandments' eyes widened (well, Dreyfus' did... not much to say about Grayroad's) as they were frozen and a new person joined the party.

She was scantily clad in purple clothing, had yellow eyes, and short black hair. A knowing smirk donned her face as if she knew everything.

"What... what is this imposing magical power?!" Dreyfus roared in panic at the sudden intrusion of ice, to which the floating woman in the sky chuckled and responded, "you flatter me.. this is just some run-of-the-mill magic," she gestured at nothing with her hand, giving an air of nonchalance about her.

Grayroad seemed to be going around in a bunch of different directions in panic and Dreyfus stood stock still in a fighting stance. She smiled, showing her pearly white teeth, saying in an almost sultry voice, "now then, Ten Commandments, it's time I made you my personal guinea pigs."

Grayroad shot a bolt of magic out in Merlin's direction only for it to be taken by Howzer, instead, as he threw himself in front of her as a human shield. He fell to the floor with a thud after it hit him, and Merlin and Hendrickson gathered around him, calling his name as he babbled on about not being able to see or hear or feel etc.

Merlin nodded thoughtfully as she concluded, "it seems he's lost function of all five of his senses..." she whispered something almost inaudible and nearly effective immediately Howzer sat up, knocking his head against Hendrickson's chin on his way up.

He looked around and felt his face frantically as he smiled goofily, laughing at regaining his five senses. Hendrickson shook his head, rubbing his chin as he and Merlin both stood up.

Merlin returned to her position hovering in the air so she was level with her enemy. She frowned and her brows creased as she listened to Grayroad speak to Dreyfus of her danger.

She looked up and Dreyfus and Grayroad immediately stopped their attacks at the noticeable difference in her. Her eyes were no longer their beautiful gold colour, no. Now they were a deep black. It looked as if you could almost get lost in them. As if they were the entrance to the depths of Hell themselves. They couldn't see it from their position but if they had looked close enough they would have seen the deep red streak that was now in her hair underneath.

Dreyfus looked up to Grayroad to see hi reaction to this new change in character from her and saw that he was just as confused as he was on the matter.

"What is this new change in physical appearance?" Grayroad questioned Dreyfus and Merlin, completely baffled. Dreyfus shook his head indicating he was just as confused as he was on the matter.

Merlin only smirked at their confusion even more as she allowed them to continue their conversation.

One of Grayroad's many 'faces' opened its mouth allowing a swarm of insects to fly out of it and straight at Merlin. She tilted her head the tiniest bit in disbelief, "insects?" She questioned, scoffing.

She lazily lifted an arm and, predicting her next move, she heard Ban yell, "Merlin! Don't use that!" But it was too late, she had already used Exterminate Ray to destroy every last insect that flew towards her and practically wipe off the face of the one who launched the insect attack.

The sound of chuckling made her raise a perfect eyebrow and look at Grayroad and Dreyfus. "Now you're finished," she heard Grayroad say, "those who break my commandment, "thou shalt not kill", shall have their time taken away from them until they crumble to dust," he continued with a victorious laugh.

She once again heard Ban yelling her name but after a few seconds of nothing happening, Grayroad said, "it can't be..." she smirked and folded her arms across her chest as she looked at the two Ten Commandments' dumbstruck faces. "As intriguing and interesting as your Commandment is, it shall have no such effect on me," she explained.

Ban came round so he was in her line of view and started, "Merlin then yo- what the hell happened to your eyes?!" He yelled instead. She didn't take them off her enemies as she used her magic to teleport him behind her.

Grayroad and Dreyfus looked frantic now, confused as to what was happening, "why aren't you changing?!" Grayroad demanded. She chuckled at his desperation and allowed herself a moment to explain, "I needed new knowledge. I needed to learn everything there is to learn. But, as I'm sure you know, a human's life is finite and limited. There would never be enough time and my lust for knowledge and wisdom was growing exponentially. Then it occurred to me, I needed to stop my own time," there was a chorus of people repeating her last words in shock.

"Impossible!" Grayroad yelled out in disbelief and she merely continued smirking. "Infinity," she said, "that is the magical power I possess. No matter how powerful a magic is, all I need to do is invoke it just once and I can keep flames burning... ice frozen. As long as I, myself, do not release the spell, of course," she explained nonchalantly.

Dreyfus growled in anger and took a step forward, pointing a finger at her, "be that as it may. You still haven't explained how you released yourself after being turned to stone by Garan!" He yelled. She smirked at their fear, "it wasn't easy, it took me a considerable amount of time before I could return to normal. Even I panicked even if for a moment. But then I realised, I had been given a natural resistance to the Ten Commandments to begin with," she said proudly.

The shock clearly registered on the two Ten Commandments' face as she said those words. How could a mere human have a resistance to the Ten Commandments' curses?! It was preposterous!

"It was so long ago," she continued, however, disregarding their shock, "such a long time had passed, in fact, it seems everyone has forgotten my true identity," she waited for a moment before dropping the bomb, "none other than Belialuin's daughter," Merlin claimed, staring emotionless at Grayroad and Dreyfus. "B- Belialuin's daughter?!" They both roared in response.

"We're supposed to just take your word that you're that survivor?!" Dreyfus continued ranting as Grayroad internally panicked. She continued staring at them both panic as she announced, "my true name is... [Merlin's true name]," at the sound of her name, both the Commandments' eyes widened, "then it's true then... there's no doubt about it," Dreyfus said whilst Grayroad floated next to him trying to think of a way out of this predicament.

Merlin donned a fighting stance, preparing to use her Endless Whirl on Grayroad and turn him into her experiment guinea pig. Grayroad started pulling himself in different directions as he attempted to leave and argued with himself on which way he should go.

"Not that way, you fool," Merlin heard before she saw Grayroad had successfully pulled himself apart into several different bodies with the same face. She mentally praised his determination but tsked his stupidity. "I don't remember saying you could leave," she told him in the most chilling voice as it sent shivers up everyone's spines.

Using Endless Whirl, everyone else watched on in terror but fascination as Grayroad was forcefully sucked into something resembling a tornado.

The 'tornado' slowly got smaller and smaller until it eventually went inside a test tube Merlin now held in her hands. She put a bung in the test tube and looked inside the test tube at what now resided in it, "mmm, I've gotten my hands on quite the scrumptious guinea pig..."
