Okay, my first Fanfic ever, so please don't be too harsh, but constructive criticism is always appreciated! By the way, I noticed a paragraphing error, and i will fix is ASAP. Also, these first couple of chapters might be a bit boring, but it does give some background info. I promise if you read on, then things will get better! :)

Darkness. It was the only thing present to Chen as he woke up groggily. Suddenly, a blinding light forced him to flinch and close his eyes. He found himself strapped to a chair.

'Not again. Please.'

Chen had been with the 'project' long enough to know resistance was feeble. Cuts and scars engulfed his entire body from their previous experiments. His aura had been suppressed, so there was practically nothing that he could do to stop them inflicting pain and torture on him. Two whole years of it. He was only thirteen. He had never felt so alone in his life. He was meant to live a happy life, with his two sisters and his parents. Suddenly, the sharp pain of needles and scalpels exploring his fragile body. He winced as looked at the people inflicting this pain. To his horror, they belonged to the very people he loved. He saw their stares, the blonde, thick mane of hair, and the dark brown hair with red highlights. He heard an evil cackle as he began to fade away from consciousness…

Chen shot open gasping for air. He lay in his bed panting as he slowly got used to reality. When he calmed down, he sat up and looked at the clock.

4:30 AM

With a groan, he lay back down. He'd had that nightmare countless times. He'd tried to shut out the memories of what happened back then, but they always came back to him in the form of nightmares. Obviously the real memories didn't include his family doing the torturing.

The people at the project never told him what was happening. Every day, he would be taken out of his cell, and for the first few months it had just been tests being run on him. Then it got worse…

For two years he had to endure all that pain. And although it had weakened him, in a way, it had also made him stronger, more aware of the real world. Despite all this though, he was now free.

One day he had just woken up, and found no noise there whatsoever. He remembered being rescued by government agents, and taken to a care home. Then he had been found by his family. Well, what was left of them. Only his sisters had survived the very attack that led to his kidnapping.

Chen had been lost, separated from his family, wandering through the forest, miraculously avoiding any Grimm, until he had reached civilization. However, the 'project' that he was taken to, thought he was homeless. He'd been too young and confused at that point to comprehend what was going on. He thought that they were rescuing him.

His sisters had been looked after by their Uncle, a man that Chen looked up to immensely. However happy he was to see some of his family after all that he'd been through, he was inwardly seething at the death of his parents, and the treatment he had received by his tormentors. His feelings had been mixed. First, it was happy to see his sisters and uncle again, then pure sorrow at the news of his parent's death, and eventually the anger and resentment. Shortly after he turned sixteen, Chen made one of the hardest decisions he ever had to make. He left his family. He left to seek vengeance on those who had ruined his life. He'd picked up information about members of the group still evading capture. He had disappeared with a sorry note. It broke his heart to be separated from his loved ones again, but his thirst for revenge would not be quenched until he achieved it.

He spent several months locating these members, and found them. The police must have been really incompetent if a sixteen year old boy could find them but they couldn't. Chen had found the perfect chance to kill one. To get his revenge. Weirdly, he didn't have the heart to do it. The revenge he wanted was gone. He mentally slapped himself at the missed opportunity, but nonetheless tried a different criminal. The same result. That had happened several times, and by the time he was seventeen, he realized something very important. He was better than them. They deserved to pay with their lives, but Chen knew he had to let go, so he didn't stoop to their level. Maybe that was why he hesitated to kill the first person in the first place.

He realized he had wasted a whole year, a whole year without his family, or friends, or Signal. In his short time before he disappeared, he had joined Signal with his two sisters, and forged his own badass weapon. He had called it simply, Vengeance. (This was before he realized he had to let go). Basically it was a powerful rifle, with the gun nuzzle surrounded by four blades, which could also be shot, but then retracted by the fact that they were actually programmed to return to the gun.

His sisters had always called him a nerd, and he also shared his younger sister's love for weapons, and was like her in that way. He was like his twin sister in terms of appearance; he shared her blond hair and lilac eyes. But then again that was expected from twins.

His weapon was useful for long range and close combat. But his favourite part was that with the simple press of a button, the gun turned into a machine gun and the blades disappeared to be replaced by the nuzzles. He always carried two large gun magazines to insert into Vengeance in machine gun mode. Both of them were carried in a pack that he had on his back.

Chen slowly got up and stretched. There was no point of trying to get back to sleep. He looked around the small apartment he had and turned on the TV. The news showed there was a worrying increase of Grimm around Vale, where he was currently residing in. With a sigh, he decided to get changed and take a (very) early morning walk.

A few minutes later, he felt a cool breeze in the surprisingly warm morning sunrise. It was rising as early as 5:00 in the morning. He smiled and walked to a nearby park that he always visited when he just needed to relax.

Chen sat on a swing and just closed his eyes, enjoying the rare early morning warmth. The fresh air helped him to calm down and forget the nightmare/memory he'd just had. He swung slightly as he just sat there in blissful silence. Until the rumble of a motorcycle nearby disrupted this.

He looked up at a figure approaching him with a grin on her face. At first this seemed a little creepy and Chen flared his aura in case the worst happened. But then, it struck him who the figure in question was. How had she found him? He barely had time to process the mane of blonde hair and confident attitude before he felt a stinging pain on his left cheek.

"That was for leaving us."

But once again, before Chen could react, he was enveloped in a crushing hug.

"But I can't believe it! I'm so happy!"

"Yang?"

I know that the plot seems a bit dodgy, but that's something I'll have to work on. If anyone could give me few pointers, I'd be really grateful for that! I know the chapters are currently quite short, but I'll be looking to write more from now on :D
