Ada Wong, Alex Wesker, Chris Redfield, Jill Valentine and all Resident Evil series characters are not mine, but CAPCOM's property. Kain is mine, though.

Prologue

Two years had passed since the incident in Kijuju. Jill Valentine, a former STARS officer who had been missing after the incident in Spencer Estate, and considered dead, had appeared along with Chris, Sheva and Josh. Wesker, the international bio-terrorist which caused hell to Chris and Jill's lives for more than ten years, was finally dead. Jill had received a warm welcome home by her friends, even after being barely more than a pet at Wesker's hands. Still, she had to undergo many exams to check if every single thing was fine with her body, in special, the T-virus. But, in the end, all ended up right, and in some time, she was again Chris Redfield partner. Sheva and Josh remained in the West African branch of BSAA, still fighting the biohazards in that area, but keeping contact with they, especially Chris. With those four agents, and some others prestige member of the BSAA around the world, bio-terrorism was slowly coming to his extinction.

… Or was he?

Part One

In what looked like some kind of underground lab, a man with blonde hair could be seen. He had a scientist outfit, with the exception of the use of a orange sunglasses, which made it impossible to see his eyes. That man, was dangerously close to the appearance of another person: Albert Wesker. But, that was not his name. No, no. His appearance may be like his, his intellect may be at the same level, but he was not Albert. He was Alex. Alex Wesker, the same man than years ago betrayed the very founder of Umbrella, Ozwell E. Spencer. The very same man, than discovered the secret of immortality.

It did not take long until another person came into the lab. A woman with asian traces, and short black hair, also dressed into a scientist outfit. A woman, know as Ada Wong. Although he heard she coming near, Wesker didn't bother even looking at her, instead, walking towards what looked like a test capsule with liquid inside it, and what more, with a man inside. The man inside it was naked, having short brown hair and a muscular body, something usually only heavily trained men would have. Ada soon approached Wesker, staying behind him, while looking at the man:

"So… I guess the Angra Mainyu is ready, is it not?" She asked

"Yes… his growths are simply amazing. He has the strength, resistance and vitality of one of the former 'Tyrants' of Umbrella. Yet, there is one great thing that can backfire against us…" He said

"What is it?"

"His mind. The Angra Mainyu was created by giving… updates, to a former normal male human. Those updates made him quite strong, however, something with his mind is far stronger than this. He isn't the most brilliant life form, far from it, in fact. But his mind is strong. Outside 'suggestions' have little to no effect on him."

"You mean, you can't really control it, huh?"

"Correct. At least, not with some kind of mind control device. I managed to clear his head of some memories of his past, however, and implant new ones according to our Organization interests. But that is as far as it goes. He can't be really controlled, and his personality is still the same from when he was really human."

"Why don't you just get rid of him and start again, with a new one?"

"It isn't that easy. People suitable to become a Angra Mainyu are very rare, and thus, difficult to find. We got lucky to have found this one. Even thought he have some errors, he must be used. And, he must be release."

"You're going to release it? But didn't you just say that you can't control him?"

"True. I, in fact, can't have a direct control over him. But, I can give him some 'ideas' of what to do."

"… Manipulation."

"Indeed. I can't force him to do something, but I can make him want to do something. I said I implanted some new memories in his mind, correct? Well, those memories are in fact some memories of some… nuisances of our organization, which must be taken care of."

"You mean, Chris Redfield and Jill Valentine."

"Yes. But, not only they. There are some other people which may prove to be a delay in our plans. Our friend Angra Mainyu here will take care of they for us."

"And after he's done with they?"

"After it, I may as well put him again to sleep, my dear Ada. At least, until I can uncover a way to control his actions according to my will. Now, dear Ada, I think you will want to step away. It's time… for him to come forth."

As Ada heard that, she did as she was told and stepped away from there, while Wesker pressed one button near the test capsule. As he did this, a sound echoed in the lab, as the liquid inside the capsule slowly began to disappear, and the man opened his blue eyes. Wesker as well stepped away from the capsule as it front began to open, but without waiting for it to completely open, the man jumped from the capsule, landing in front of Wesker and Ada. He looked at one and at another with a suspicious glare, like if he was trying to remember if he knew they, but Wesker only smirked at this, and soon, he began the talking:

"It makes time since we last meet with you conscious… Kain." Wesker tone was different now. While talking to Ada, he kept a serious, strict tone. Yet, now he was talking to the Angra Mainyu, his tone, even though still serious, was more friendly.

"Kain…" the man spoke slowly, while looking at his hand, only to look again at Wesker soon after "That is my name. Do I know you?"

"Your memories still didn't come huh? Well, I guess this is expected, since it has been quite a lot of time since you were unconscious."

"Unconscious? What happened to me?"

"You, Kain, was attacked by a group of trained and professional military soldiers. The attack was made because it was discovered than you had a rare thing in your body, than makes you able to control virus, which are used by many bio-terrorists around the world. If they found you, they would use you as a source to make their weapons, and that would put the government in a very bad situation."

"They… they set me up? What the hell are you talking about? And who are you? Or this woman?" With that, Kain pointed at Wesker and Ada, with anger in his eyes. Ada took one step back in precaution, but Wesker just smirked.

"I am your friend Kain, and so is her. I was one of your friends before the attack towards your person. My name, is Alex Wesker."

"Wesker…" Kain repeated the name, vaguely remembering someone called Wesker talking to him in the past "Yeah… I remember you."

Wesker smirked again upon hearing this "Good, looks like your memory is coming back. This one with me is Ada Wong, a friend, by all means. But, coming back to what is important. After all that happened, I found you, near death. But, you see, I have some affiliations with a organization, and that organization is a pharmaceutical industry. So, it was simple for me to know what to do. I tried nursing you back with many medicines, but none made anything to improve your condition. That is, until we found the right one."

"Right one? What is it?"

"It… is a virus. But don't worry, it isn't as dangerous as it sounds. We were testing that virus, since we believed he may have some medicinal uses. We aren't some crazy and disgusting fools like the ones from the pharmaceutical industry called Umbrella. We care for people. Anyway, that virus managed to recover your body to its original condition… or almost it."

"Almost? Quit the suspense, tell me what happened once and for all!"

"As you wish. The virus not only cured you Kain. It also gave you some abilities beyond the ones of average humans."

"Abilities? What are you talking about?"

"Strength, speed, resistance, vitality… your body is far stronger than the one of any other man or woman living in the world. It is… perfect."

"Oh right. And why would I believe you?"

"Because of this." Why that, without waiting for a reaction, Wesker quickly pulled from his scientist clothes a small revolver, which he fired without thinking twice against Kain chest. Kain was surprise, he didn't even had time to dodge, not that he ever needed. The bullet hit his chest, but that was all that happened. It didn't penetrate. It didn't hurt. It was just like if a fly had hit his chest while on flight.

"What the… you just shot me, you bastard!"

"Only to prove to you than I was telling the truth. You're not like a ordinary man anymore Kain. Besides, it may help make you remember your past."

In that moment, a flash passed though Kain's head. He could hear voices shouting things about orders, sounds of gunfire, he could see blood, and he could see faces and weapons. His hands moved to his head with this, and soon, he talked again:

"Wesker… I remember. The attack… you was right…"

"So, it is coming back, I see."

"Who… who were the ones who participate in that attack?"

"You want revenge?"

"… What if I say 'yes'?"

"Then, I'll say I'm going to assist you in this."

"You will?"

"Of course, can't leave a friend alone. Besides, I figured you would want vengeance against they after you woke up, so I made some investigation on this. All of they are of the government agency called BSAA, except one government agent. You'll find something about they in here." With this, Wesker takes out from one of the pockets from his outfit a file, which he handles to Kain.

Kain started looking into the file. He had several pictures of some people who appeared to be officers, which Kain gave a look, right after seeing they in his past. He then passed to the second part of the file, which contained another small picture of the officers from before, along with a small piece of information:

"So… those are the guys… and girls." Said Kain as he looked at the pictures once more.

"Yes. They are those which made the attack towards you Kain. Now that you know who they are, do you still wish to have your revenge?"

"Of course. I won't stop until I rain vengeance like hell in those sons-of-an-bitch!"

"I thought you would say that. Come with me Kain. I'll get you some clothes, and give you some details about the ones closer."

"Ok. Wait, what? I'm naked? HOLY HELL!"

Part Two

Three days after Kain liberation, on the BSAA headquarters in New York, it was late night. Chris was leaning his back on his chair, a lot of paperwork done on the center of his desk and a lot more to be done on the sides of it. Jill, on the other hand, was just finishing putting it all together, paperwork already done. Chris always had some kind of admiration for the woman: she was cute, she was beautiful, yet, she still was hard and focused on her work. Even so, she still had grace around her, something than made him feel attracted to her, more and more. He found himself staring at her now blonde hair while she was gathering things: he didn't really like blonde, the brunette type was pretty more attractive and suitable for her in his thoughts, still, even with that blonde her, she was indeed beautiful. Unfortunately for him, she saw him looking right at her:

"What's the problem Chris? Not going to finish you 'homework'?" she said, white pointing with the index finger toward the paperwork he still had to do.

He sighed "I'm thinking about really letting this as a homework. This thing just never ends! I've been here all the time, doing this, and yet only a thirth of it is done!"

She chuckled "Maybe if you would focus more on your work instead of staring at me, you would get it done sooner."

He looked at her, with a surprise expression on his face "You noticed?"

"Hard not to."

"Oh man…" he took one of his hands right up his face "You must think I'm a pervert now."

"I always knew you had that side in you, Redfield." She said this and smiled, to say right after in a low voice "Not that I don't like the attention."

"Say what?" Chris lifted one eyebrow at this.

"Nothing."

"I see… so… Jill, um…" he passed a hand at his hair, trying to calm down and come up with the words "I've been meaning to ask you this ever since Kijuju, and I know it already makes two years but, do you…"

Before Chris could end speaking, the door of the office slammed open, with the body of a unconscious BSAA guard flying though it. Chris and Jill quickly reached for their guns on instinct and pointed they towards the door:

"The hell?" he said

"Who's there?" she asked

"Well well…" they heard a voice from where was the door "Chris Redfield… Jill Valentine… I may as well begin my revenge by you two."

The voice who said that finally showed up, bringing Kain into view. He now wore a white T-shirt and long pants, and his eyes, where gazed upon Chris and Jill:

"You two will be very sorry be what you did to me." As Kain said that, he entered a fighting stance. A fight would begin there, soon.
