A man can be seen standing in front of a mirror while inspecting his figure. His face show he is very sad, he feels like he wants to suicide, but for some reason, he can't die.

He tries various ways to suicide, but all of them not be able to kill him. Now the last plan for suicide, taking some drugs. Again, it doesn't have any effect on him. It just makes him tired and sleeps for a few days.

Y/n: *sigh* I wonder why I can't be strong.

This is Y/n avatar, he tries everything to be strong, but he stays the same way he is. He doesn't even have the power to make him a bully prey. Even when he gets an experiment by some crazy scientist, he is immune to their project. Y/n even can't be cursed or get sick, but he can still feel the pain by getting hit or get blasted away by some power.

He has a title like King, and many more, because of his wife that he married. But since Y/n is paranoid and thinks his wife is just a burden for them, he avoids all of them, including anyone he sees. Y/n is a victim of bullying because of the title he holds. Because of this bullying, his instinct changes to make him avoid everyone he sees.

Y/n: Should go to that training simulation place. Maybe I can get some tips from their fighting.

Wearing a shirt before he goes to the kitchen and washing his face at the sink. Then he gets out of his house and goes to the Simulation place.

He tries to avoid meeting and talking to anyone in the street because he is scared they might hit, insult, or bully him.

*Phone alarm*

Hearing this he felt his heart clutching slowly. But he regains his composure and grabs his phone to see who is calling him. And it is one of his wives, Theresa, Queen of Sarkaz.

And Theresa is one of his wives that he will try to not meet since he is Queen. This makes him target many people that want the thrones, especially her sister Theresis. Don't know her true intention why she wants to kill Theresa, but Y/n doesn't want to investigate nor want to get involved.

"How did she get my number again? Goodbye, my 69th phone. How many phones do I need to buy again, plus, how will she be able to know my bee number?"

He then crashes his phone by throwing it at the floor before grabbing it back and putting it inside the trash bin. Sighing he continues to the location he is after too.

[Log in to Avatar 0%. . .]

"What the duck? What is this blue thing? And why does it say 'Log in to Avatar?' Am I hallucinating? No, I haven't taken drugs for a long time so my mind is clear right now."

[Log in to Avatar 1%]

"It rises, s-should I call my wiv- No, I can feel they will think of me as an annoying person. They must hate me and pretend to care for me. I should deal with this on my own at home later after watching a fight I guess?"

(Timeskip)

He finally arrives at the Training Simulation Place, in short TMP, a place that should be used as a tournament, but the host meets a bigger place than this place. Mainly people come to this place to train themselves by putting on a holographic of choice.

Some people will choose to fight S-rank monsters to prepare themselves when they enter S-rank. And maybe, they will try to fight legendary heroes and villains, but mostly they want to fight someone from a few years ago.

This person is strong enough to the point he doesn't get any scratches when fighting various people. Some people are glad he is gone, but some of them are sad because they want to see him in action again.

Back to Y/n, he buys popcorn and some soda before entering the place and finds a lone seat. He doesn't like crowded places. In his mind, he thinks there are various ways for him to get killed by one of the people sitting close to him.

"Seat, a lonely seat, hoping I found one, I can't enjoy the fight without eating popcorn while standing. It is my motto. *spot a seat* Found one, it doesn't have anyone around the seat, and it is far away from people. I bet nobody will go far to sit at this seat."

Sitting at the bottom of the seat he found as he watched a match between a fighter while eating popcorn. He seems to enjoy the match because the fight is awesome and epic, but sad since he can't get any stronger. Without her knowing, one of them is a player waiting for Y/n to log in to his avatar.

This man is Mike, a pro-type player, and he is grinding every day after his defeat by Y/n. He can still remember Y/n humiliating him in front of thousands of players and NPC.

Mike: "Y/n, today is the day you will log in to your avatar, and it will be your last day in this game. I can't forgive what you did to me back then."

In this game, the rule is kinda dangerous, very dangerous. It is simple but deadly for players. Once your avatar gets killed By a player, all of your stats, weapons, achievements and everything you have will go to the winner.

But if you get killed by an NPC, you can respawn back at the beginning of the place you spawn. You can even Active or turn off 'PVP' mode, if you turn it off, you will never get hit or killed by any player since it is a mode that prevents you from getting killed by any player. It is a good mode for peace players or enjoyed players.

But, once you activate it, you need to wait 24 hours to turn it back off. A Warning has been given to players 5 times if they want to turn on the PVP. Don't blame the system if you die, blame the idiotic of yourself and how weak you are.

[Log in avatar 93%. . .]

"It's so close to 100%, I wonder what will happen if it hits 100%? Am I gaining a superpower? Or can I have strength as other people can do? Maybe, I will get isekai to another world to be a hero, then I come back to this world and show all of them who's the true hero."

While he daydreams while watching the fight or training. Y/n notice a man looking at him with killing intent. Since Y/n never experienced something like this, he thinks the man just looks at him, nothing special, and no homo.

"That awesome looking armor man is looking at me. . . should I run away? I don't think so, he just looks at me, just ignore him Y/n, he will change his stare at someone else. Plus, I can feel the peaceful aura coming from him. I hope there are many men like him In this world."

Mike: "Once he Logs in, I will immediately chant my powerful magic and shoot at him! Without time to prepare or react, Y/n will die immediately! And all of his belongings will be mine!!! I can L him back after he L me a few years ago!"

[Log in Avatar 100%. . .]

"Ohhh, it's 100%! What will happen to me?! I can't wait to see the result! Maybe I w- Huh? What the f*ck is this place? Training simulator? Why am I here? And why am I eating popcorn and drinking a soda? But it is not like I am against it, it is top tier for when in cinema."

This Y/n then stands up while stretching his body before looking around. He just noticed his avatar sitting in a lonely place.

"Why am I sitting in a lonely place? Oh wait, I am lonely, I don't have any friends, besides NPC and some monster or boss I guess? Well, time to check my status, I wonder what has changed over the past few years? Status."

When he mutters those words in his mind, a blue panel comes out in front of him, invisible to the NPC, but not to the player. This goes unnoticed by Mike, Y/n the player that humiliating him just logs in to his own avatar. It's time for his revenge. It's time for him to humiliate Y/n back and spam L at him.

Mike: I'm. . . As a Paladin praying for a blessing as I wish-

While he is busy chanting, we switch back to Y/n that is staring at his stats or status. Nothing has changed at all, it's just the same as it was a few years ago.

[Name: Y/n]
[Age: 20(Immortal)]
[Title: Yes(Yes)]
[Class: Parasite(First Form)]
[Level: 9,999(5B/1T)
[HP: 10 (Core of Health)]
[Mana: 10 Core of Mana)]
[Durability: 10 (Core of Durability)]
[Agility: 10 (Core of Agility)]
[Attack: 10 (Core Of attack)]
[Defense: 10 (Core of Defense)]
[Speed: 10 (Core of Speed)]

{Core: This Core gives your stat a x10. Plus, it will hide your true stats from the enemy, including yourself. If the player wants to see their stats, they must deactivate the Core hidden effect so the player and other players can see your stats.}

"Ah yes, perfectly balanced. I can't get defeated if I'm and my enemy doesn't even know my real stats. This core is God-tier Core, I'm lucky I finish all side quests first, maybe I should do the Main quest? Players can't interfere if they're doing a mission. Time to teleport to Theresa I guess? Maybe I just want to see if she is still alive after a few years have passed and I am leaving this game until this day."

He then goes to open space to teleport to Theresa. Closing his eyes he thinks one word in his mind. This is one of his skills and power, Teleportation. It can teleport Y/n anywhere he wants without making himself tired.

"Teleport"

. . . nothing happens. Weird. He supposed to have plot armor right now.

"Teleportation?"

. . . Again nothing happened. Seeing this doesn't work, he tries to do it another way. By speaking.

Y/n: Teleport?

. . . again nothing happens. Poor him.

Y/n: Ummm. . . Teleportation?

. . . again nothing happens. Come on Y/n, I'm tired of typing the same word again and again. My idea for the plot is fresh right now, better do it fast Y/n.

"It doesn't work? I know, I must shout like I did when gaining this power for the first time!"

He then drinks all of his soda before coughing a few times to check whether his throat is good or not. Everything is good, taking a deep breath as he opens his mouth.

Y/n: TELEPORT!!

. . . nothing happens at all. But it is different, everyone in this training place looks at Y/n. . . even the audience. Y/n doesn't mind them all since they are NPC, except one player that still does finish their chant, Mike.

Mike: With the power of you, my Paladin, I will finish my goal from the past, with this I can perish an evil being, but this being is not evil, it is so evil and rude, it spam L at me. So let me borrow your power Paladin, I need th-

Y/n: TELEPORTATION!!

. . . *sigh* nothing happens, just give up and kill the player Y/n, I don't even know how long is his chant word.

"Crap, I forgot what word I need to use to teleport! Bruh. I should check my skill list, maybe it can help me? Checking Teleport power and skill."

[Skill]
{Teleport: The player must think of the place the player wants to go. Imagine you are going to that place.}
<Hint: Imagination>

"Ohhh. . . now I get it. Time to kill that player chanting nonsense. Why doesn't he just chant 'Paladin strike'?. That is the name of Ultimate skill right? Why does he chant-like he is just reading nonsense chant books?"

With a blink of an eye, Y/n vanishes from the spot he is standing to as he appears to the side of the player before kicking him to the side sending him to the wall.

Mike: Arghh!!

Before Mike can do anything or react, Y/n in front of him grabs Mike's face before throwing him like a bowling ball to the floor. He then appears on top of Mike and stomps him many times as Mike's health decreases in huge amounts every time Y/n stomp on him.

Mike: "Shit! I can't survive like this! What class is he?!"

Y/n: *stop stomping* Parasite.

Mike: P-parasite? Is there a Class like that?

Y/n: Yes, you must reset your progress 100 times every time you reach level 100. So what is your level?

Mike: 478.

Y/n: I will apologize, bro, because your progress will reset to the start.

Mike: No! Please spare me!! I will do anything! What do you want?!

Y/n: I already have what I want.

With that, Y/n stomps on his face as it crashes Mike's head, killing him instantly. Then, a blur panel appeared in front of him.

[Mike just got stomp to the death By Y/n]

"Oh, I forgot this thing, but at least it doesn't tell anyone the location. I wonder if he has anything interesting on him?

[Mike]

{Reward: 360K Exp, a legendary Paladin weapon, legendary Paladin armor, legenda-}

" Refuse, I don't need Paladin and that EXP, it's too little. Plus, I hated using weapons, I prefer close combat since it can show me how terrifying I am."

Officers: Hand up!

Hearing this, Y/n looks behind him to see a thing he always sees. NPC. Every time he kills someone in public, an NPC officer will appear to arrest him or kill him. There is a star, for now, it is 2 stars since they killed someone. If it reaches a 6 star it will annoy him, many Stronger NPC will find him and kill him.

For him, it is nothing since he has gotten 6 stars many times. But other players, it is suicide since they need to fight many stronger NPC that can fight them without trying. Only Y/n and a few other players can fight the NPC head-on.

But sadly, other players that can fight 6 stars NPC dies, killed by Y/n. Y/n hated them since they have too much ego inside them. Plus, bothering Y/n many times for fun.

Y/n: Yes?

Police: Don't you hear me?! Hand up! Before I shoot you!

Y/n: "They are not players, after ignoring them, my body is immune to firearms as well. *sense something* I sense some players nearby." But first, devour this dead body. My Carrion form is small for now.

Police: Devour?! What are you trying to do?!

Y/n go to the corpse before pointing his hand toward it. His hand then slowly opened as a pair of sharp teeth were seen before launching at the body and eating it. The Police throw up as they see the dead body being eaten by a thing from Y/n hand.

"Wait, can an NPC throw out? That's new. I think there are many features I miss right now. I will check it later. Now, who I should kill next? Random NPC? Or this police behind m-"

A light appears as a few groups of people teleport into the scene. Seeing this, other NPC cheer for them.

NPC: Look! It's the chosen one!

NPC 2: We are safe!!

"Chosen one? From what I remember, 2 out of 10k players will be chosen one. This player is a lucky one."

Chris: Don't worry you all! I will defeat this mons- *notice it Y/n* Oh My God!!

The team member beside him is confused until they see who's the killer. Y/n, everyone still remembers that name even after he retired for a while. They see an announcement of Mike getting killed by Y/n. They don't think the mission of saving civilians will make them meet him.

Evan: It's you!! Why are you here?!

Y/n: I killed some players. So you must be chosen one right?

He says that while looking at Chris, he tries to stand still and be brave. But inside his mind, he was very scared since he had never seen Y/n fight before, but he heard a rumor that he killed half the population of players within one days because he gained a Legendary Destroyer Sword.

Chris: Yeah! It was me who was the chosen one! Your tale will end here Y/n!

Y/n: *chuckles* You are wrong. Your tale will end here. Not me.

The group of heroes hearing this feel a fear they never felt before. Now there is no turning back, they must try to kill him before he kills them. Keyword 'try'.

"Change Form: Carrion"

Slowly, his body emerged with red tentacles as his face slowly opened to reveal sharp teeth. Few eyes appear on his neck as he falls into the floor before all of his eyes turn red. His clothes too are transformed into Carrion.

The group and NPC seeing this can't move as they just see a most dangerous Parasite in this RPG game. Carrion. Some rumors say Carrion is Y/n power, but it is indeed true since he is a parasite class type.

Y/n: It's been a year since I retired. Now my goal is clear, and it is killing as many people as I can to gain a final form. Be grateful. You will be killed by a legendary parasite or a legendary player. . . you guys can choose to call me one of them.  By the way, this is small form, don't worry, my reason is connected to this form. After I kill, I will eat them, like some parasite should do. Duh? Never wacth Net Geo Wild before?

The hero then prepared all of their power as a mage beside them cast many of those buffs on them. Seeing this Y/n smirk in this form as they feel a shiver on the right of it.

Y/n: I like you all. . . as an enemy, nothing else. Don't think otherwise. I hate it when someone thinks otherwise.

To be continued

So, how was the prologue, half good or bad was it?

Do Y/n class is a parasite, which means he can be any parasite he wants. So his army will be parasites too, but what type? There are many parasite monsters out there.

You guys decided. But Carrion is his main form.
