In a certain lab, there are two people walking while discussing the operation that their about to perform. One is the the lab professor that managed the whole project in making assassins with enhanced abilities that surpasses a normal human, while the other is the boss of the organization that the professor was working for.

"So, how is the test subject that you recommended to me?"(Boss)

"It's great boss, though there are some slight problems about the test subject..."(Professor)

After the Boss heard the word "problem", it made his expression disappointed causing the Professor to slightly panic.

"Don't worry boss! It's only a minor problems regarding the test subject's mentality."(Professor)

"And what are those "minor problems?"(Boss)

"Well.... while the test subject was undergoing the enhancement experimentation he developed a mentality problem that caused him to change his behavior and doing aggressive things. Just a while ago while we were about to do an experimentation, he stabbed one of the researchers eye with a pencil and attempted to escape but quickly was neutralized by the guards"(Professor)

The Boss' disappointed expression disappeared after hearing the Professor's answer, after they walked for a minute, they finally reached their destination.

Their destination was the room where Test Subject 17 was held. The Professor started to open the door by putting the password in the security system. After they opened the door, what laid upon their eyes was a man tied up with metal chains all over his body. The man had a messy white hair, red eyes, good physique and wearing only a white t-shirt and a black pants.

After the man realized that there are people in the room, he started to grin and looked at the Professor's direction, and started to speak.

"Oh hey Prof! Are we going to start our "fun" operation today? You told me last time didn't you?"(Man)

"Yes, today is the day of the operation of you turning into our assassin"(Professor)

"Hah! Me becoming your assassin? You think I'm going to let become your puppet and just go over with it?"(Man)

The man closed his eyes for a second and then glared at the Professor while eerily grinning. He glared at the Professor filled with hatred.

"I won't easily let you do it, you know?"(Man)

At that moment, the Professor felt a chill down his spine at the words that the man said. He gulped his own saliva and quickly left the room with his Boss. After they leave room they went to the lounge room to discuss about the man. The Boss grew interest about the man and asked a few questions to the Professor.

"That man earlier... I think he's perfect to be our assassin, the way he looked at you was like a real natural killer. Professor, I want to know more about Test Subject 17."(Boss)

The Professor was stilled frightened from earlier but quickly maintained his composure to answer the Boss' question.

"Well actually we don't really know much about his background information, so I can only tell you boss a few things."(Professor)

The Boss nodded and ordered the Professor to continue.

"When we scouted for individuals, we wanted someone that don't have much connection in social, so that it won't cause much problems. Then we peaked our interest in Jeff also know as Test Subject 17, at the time when he wasn't still our test subject he was a shut in with no parents, friends or even acquaintance so we decided to scout him. When we checked his background data we didn't really find much, after that we that we tricked him to join our organization. His mentality was excellent being able endure the experimentation without completely losing his mind though his behavior changed in the process, we still successfully completed the full enhancement project in him. Now his strength, agility and other abilities have dramatically surpassed of a normal human."(Professor)

Satisfied by the Professor's answer, the Boss stood up and talked.

"Hmmm... I see, well then.... how about we start the operation now?"(Boss)

The Professor also stood up and replied.

"Yes boss, let's go now."(Professor)

As they were about to leave, suddenly the room was filled with red lights flickering on and off. An announcement was then given by next.

"Warning, Warning. Test Subject 17 has escaped. I repeat Test Subject 17 has escaped."(Announcer)

"What's happening!? Professor give me an expla-... Uwaaah!!!!!(Boss)

As the Boss was about to demand an explanation, suddenly the door flew onto him, causing him to crash into the wall and killing him in the process. The Professor looked into his boss who is now smashed flat into wall. The wall was filled with blood like a tomato that was thrown into the wall, the boss' internal organs were scattered into wall due to the strong impact, the scene was so grotesque causing the Professor to almost throw up.

"Here's Jeffy!!!(Jeff)

"Hiiiii..."(Professor)

Before the Professor's eye was Jeff grinning mischievously, the chains that was in Jeff's body is now gone, sweats started to fall like a fountain in the Professor's face, because right now he knows that what will happen next, he's not gonna like it.

"Prof... you know that I've waited a long time for this. Oh! I also want you to know!!!(Jeff)

Jeff started to walked in front of the Professor, and then he brought his face to closer to the Professor's and smiled. After that he whispered at the Professor's ears.

"YOUR GOING TO HAVE A BAD TIME."(Jeff)

At the room where Jeff is, loud screams can be heard from there, screams filled agony and despair followed by the sound of something being stabbed.

Scream, scream, scream. Stab, stab, stab. The continuous scream and stab echoes through the hallway. After an hour a team of 10 armored soldiers appeared in the hallway. They moved into the position in front of the door where noise came from. Then, there appeared a man showered in blood, smiling like it just finish doing something enjoyable.

"Stay where you are or we will shoot!"(Soldier)

"..."(Jeff)

Jeff just stared at the soldiers who are all now locked their gaze onto to him, watching and preparing for what comes next. All of them are now aiming their guns loaded with anesthetic. Why anesthetic? Well, they know that even if they have real bullets it will only buy them a little time because of the monster in front of them. Jeff who have an enhanced body and also having the had an accelerated healing due to the experimentation. A few seconds has passed, Jeff suddenly putted his hands in the air.

"All right, I surrender~~"(Jeff)

After hearing the words, one of the soldiers began to walk holding a handcuffs. When the soldier was a meter close to Jeff....

Blood once again is about to be scatter

"Just kidding~~."(Jeff)

Jeff ran towards the soldier who went forward him and pierced the soldier's eye with his index and middle finger. Jeff's fingers pierced through the soldier's helmet because of the abnormal strength that he possessed.

"Now you see me, now you don't!"(Jeff)

"OPEN FIRE!!!"(Soldier)

The soldier began to fire their guns directly at Jeff, however Jeff used the corpse of soldier to shield the barrage of bullets. Jeff used the wall to accelerate towards the soldiers while using the corpse as a shield. He crashed on two of the soldiers, causing them to die immediately due to the impact. Using one of the corpse he killed, he threw it towards the other soldiers. The ones by that were hit did not immediately die but only knocked them out.

"Striiiike"(Jeff)

Jeff chuckled as then again he began move towards the other soldiers, picking one of the guns that the that soldiers used, he then exchanged bullets to the remaining soldiers. Due to the armor of the soldiers were using the bullets that were shot to them just bounced and fell.

"Hey~~, you cheaters.Oh well."(Jeff)

Jeff realized that what he was doing was futile so immediately switched tactics. He threw the gun he was using towards one of the soldiers. The gun pierced through the one of the soldiers stomach, afterwards Jeff then again threw one the corpse at the soldiers.

"4 to go."(Jeff)

Only 4 soldiers were left. The remaining soldiers know that what they were doing was useless, they know that they can't win against him. Jeff realized the fear that began to appear on the remaining soldiers' face. Not wanting to waste his strength, he used the favorite "thing" he always loves to do, striking fear into the hearts of his enemies.

Jeff glared to the remaining soldiers while maniacally laughing .The soldiers' heart beat speed began to rise as they stare at the monster that was looking at them while laughing like he's enjoying what he's doing. As the monster slowly walked towards them, the only thing could was pray and close their eyes waiting to be killed.

When they were about to be killed the lights suddenly went off, after a few seconds, there began a new announcement.

"Self Destruction Activated.Countdown in one minute."(Announcer)

After a few seconds a huge bright light swallowed Jeff's vision.
