Chapter 1: Omegas

Chapter Text

Betty needed Omega. This is a shame, that she was working with Omegas, but she doesn't have one for herself.
- Bubblegum! I'm going to the Omega's shelter for one! - she shouted to her friend, who was doing... Something. Something what Betty doesn't want to know. Bubblegum always experimenting with weird things. On Omegas of course, they work in Omega's Centre and Tests.
Bubblegum stand up and said - I want one too! I am going with you.
- But... - Betty wasn't sure. - You are... Specyfic when it comes to Omegas. You like to test everything on them. What's gonna happen when you kill your own? You know, you can go to jail for that!
- But... - the pink girl was very stubborn. - I want a mate, not only a test subject!
- Eh...okay, you can go with me. - Betty sighed. - But the director Glob have to know about its, he only knows about me going to the shelter, for now.
- Okay! I got it! I am gonna tell Mr Glob right away! - Bubblegum saluted and go out of Betty's room.
...

- And then the monster BLOW UP! - Marceline, a weird Omega, told everyone in The dining area, the end of the story. - The guts were EVERYWHERE! And they stinked! Very much! - Marcy smiled with satisfaction on her face. She always liked gross stuff, not like Omegas should. The girl have dark skin, Black long hair, which she up in a ponytail and practical clothes. Her fangs was longer than others, and she always jokes about them belongs to a vampire.
Simon, the latest catched signing in The shelter, turned white and put the fork away. - Marcy, please! Not when we are eating. The men Has come here few days ago, but quickly befriend the oddball in The group - Marceline.
Other Omegas were afraid of her and don't want to be near her.
Well, Simon was the older men, he saw worse things that odd Omega.
Beside... He wanted to take care of her, he feels that she need some parentaial figure here.
- Simon, Simon! - Marcy shaked her head. - You don't understand! That's exactly the Perfect time!
- This not gonna be the best way to befriend anybody... - the men poked the rest of his dinner by finger. He wanted Marcy to have more friends than only him. - Aaaaaand my apetit is gone. I do not like my imagination...
- You are all no fun! - Marcy murmured. - What a shame!
- Quick everybody! - one of the Omegas shouted. - The Alphas are coming! We need to be the best version of ourselves!
Simon sighed. He hated it! Everyday were few houres when Alphas come to the shelter and watched Omegas to choose one.
- What's the big deal?! - Marcy hummed. - They come here like EVERYDAY?
- You say that, because nobody will ever choose you! - other girl snapped her.
- I AM GONNA DESTROY ALL PART OF YOU! - Marcy shouted angry.
If Simon doesn't hold her, she would tear the younger omega apart.
- Hey, Hey! Marcy, please! - Men was trying to calm down his friend. - What I told you about about using violence?
- B...but do you hear what she said to me? Violence is the Perfect answer for that!
- NO! Violence isn't The answer!
- Yes!
- Marcy, no!
- Marcy, yes!
Simon Had to hold her closer.
...

Meanwhile Betty was waiting for Bubblegum and cursed a little. She could go already, but now she Have to wait.
- I Hope you will get your permission...- she whispered to herself. Bubblegum was a little... Problematic worker for Glob. Her experiments could hurt Omegas and often it's happenen. Director was given many complaits at her methods.
So she was worried about her.
- Oh please Glob... Give her permission... Please, please. - Betty wanted to go already. Omega... It was her dream. The best one: cute, small, energetic and super sweet person! She would buy a lot of toys for them, give them a lot of cuddles, attention and hugs! Oh, she cannot wait!
Finally PB come to her room. Betty beathed a sigh of relief. - You already late! Go, go, go! - she pushed Bubblegum.
They left the Centre.
But in director room the curtain was moving.
The Glob was watching.

...

In The shelter every Omegas were preparing themself for Alphas. They need to look flawless! Every one of them were thinking: maybe today they will choose me?
Omegas cannot function without Alphas. Getting one means that there can leave this place and live their lives.
And of course giving birth to the puppies! Purpouse of the Omega was the first - give Alphas children, a lot of them.
Well... Marceline doesn't think that way. For her, Omega doesn't match a labor machine. She was alone with that thought. Well, beside Simon. He agreed with Marcy. He also take care of her here. He doesn't want to get ,,adopted" because this means that he will be separate from Marcy, and she will be alone again.
The Betas, who were the bodyguards and day care for the Omegas, come to help to prepare the residents too.
They get Simon, take him to the bath and washed him over.
They got him new clothes.
There was a Black sweater, Red bow, Brown trousers and grey shoes.
Well...nothing too fancy, just like Simon liked.
He put the clothes on. Betas brushed his hair at the end. The men doesn't like it, he felt like he was incapacitated.
Of course he Has a collar too. This was a Simple one with Simon's name on it.
In The case somebody will want him.
Well... He already have said goodbay to this. He was quite old, who would want to get him?
But Marcy... He needed to protect her from some perverts or psychopats.
When he was bringing over by the day carer he looked for Marceline.
He have finded her in a minute.
And almost burst into laught.
Marcy was wearing the most cute and annoying dress with bows and sweets.
- WHY THEY PUT ME IN THIS SWINE?! - she screamed aloud and started to yank the ribbons.
- That's riddiculus! I am not this type of girl to wear something like... Like THIS! - she hadn't even got a words for that.
- ...Marcy...hahahaha... You don't look...hahaha...that bad...hahaha! - Simon couldn't stop the laguh.
- Very funny! - Marceline grunted at him.
Well... Marcy always treat Betas here with hostility. They just take revange of her now.
- SUSH! Alphas are coming! - one of the Omegas shushed them down.
And they come.
Today was more of them.
...
Betty and Bubblegum was inside the crowd.
- A lot of them...- Betty was worried. What if somebody will take her Omega? She knew that she should come earlier but she was swamped!
Now she need to rush and find her mate! She heared that you know at the first sight that they are the one.
Will it be a girl? Or a boy? Or a gender neutral one? She doesn't know! She just hoped to find them!
Bubblegum meanwhile was very interested and cool. She just come to watch some cute Omegas.
Yes, Bubblegum wanted to have one too, but she doesn't want to rush things.
Not today, then maybe tomorrow?
Betty eye rolled and tried to focus on Omegas.
She watched every one of them but didn't feel anything.
What? This will be a fail? No! She have to look more!
And then...
She spotted one older men with quite long Black hair.
She stepped closer, but slowely because she didn't want to scare him away.
Men's skin was dusky, he was wearing glasses and his clothes was formal but not too formal, rather smart-casual.
She came closer.
And then the men raised his eyes on her.
Betty felt a sudden spark in her guts.
- Oh! - she blushed like a little girl.
This men... Was he the one?
...
Simon felt this too. Like sudden lightining inside his body.
- W-what happened? - he whispered, touched his chest and then he raised his head on the women next to him.
- D-did you feel it too? - she said, looked at him.
- Y...yes... - he answered slowely. The women, Alpha, looked a little afraid, but she didn't look dangerous.
- You...- she spotted his collar. - S-I-M-O-N. - she read his name on it. - That's what you are called, right?
- Y...yes...- what was the point in liying? His name was on the collar after all.
- Simon...what a pretty name. I am Betty. - The girl introduced herself. - Betty Grof. I am an Alpha and I decided that you will be my Omega! - she suddenly said and open the door.
She should wait for the one of Betas to do this, but she didn't care. She find her Omega! And she definitely doesn't let anybody take him from her!
Simon was suddenly free.
This was a nice feelings, but for a little while only. Betty catched him very quickly and hugged him very hard. She almost chocked him!
But... But... - the one thing stopped Simon. - What about Marcy? - he said to Betty. She needs to be taken care of!
- Marcy? - Betty cocked her head. - Who is Marcy?
- This one. - He pointed his finger at the girl with long Black hair, who was worring her riddiculusly cute Red dress, using her teeth. Her fangs was deeply in one of the little pink ribbon.
- Does she have a rabies? - Betty asked slowely.
- No... I think no...- Simon answered.
Bubblegum directed her attention to the wild Black girl. She watched her for a little while and said to the Betty. - I like her.
- ...SERIOUSLY?! - Betty groaned - Words fail me normally!
- Please...can we adopt her? - Simon done puppy eyes. Omegas are very good at this.
- Awwww! Look at his little cute eyes! - Betty squealed. - He is adorable! - she started to caress his head.
- You have such cutness agression, Betty! I like it! - Bubblegum told her as she was stepping slowely in Marceline's direction.
- Gotcha! - she shouted, grabbed quickly Marcy. - You will be my Omega! I want to check how you will behave under my experiments! - she grabbed Marcy by the collar. - You are so light! - she was amused.
- Because... I can float. - Marceline indeed, was floating above the floor. - Well... Around 2 metres i think.
- We will check that too! - Bubblegum was very happy. Everybody Has a different abilities because of the war and radiaton, but Omegas always Has smaller and weaker power then Alphas. Bubblegum was made from gum. And she cannot get hurt, that's all. It's great ability because she can restore herself from more of the damage, but for the calm times...well...pretty useless.
- Done! I will take you, and Bubblegum will take Marcy. - Betty said to the Simon. The men was calm already when he heart that.
- Wow, he must really like this girl. Maybe they are siblings? No...too much years. Maybe family?
Betty didn't care. She was happy that she catch Simon. Now she can finally have an Omega.
She and BG signed contracts allowed them to take Omegas from shelter.
- Yey! I have mine, and you have too! - Betty was super happy. She hugged Simon and didn't want to let him go, even when he was on a leash.
BG was holding the end of her leash, when Marcy was lewitating around two metres above the earth. She looked like a balloon with hel.
- Sooo...we should go to the Centre now! Mr Glob cannot will get angry, when we are too long out of the Centre.
- I know, I know! He liked you, Betty! I think he accounted you as a very good scientist.
Betty was Red now.
- Come on, Bubblegum! I am not that good!
- But you are!
They came back to the Centre.
Betty started to show Simon everything in The hol.
- This is room for other Omegas. But you will be with me all the time! - she poked at one big door. - Bubblegum like to choose from them, when she needed a person to her experiments. - Betty explained.
Simon turned white. Experiments? What he gotten himself to? And Marcy!
- B-but what about Marceline? - he asked nervously. - Please... Do not let this Bubblegum experiment on her!
- Do not worry! - Betty smiled. - She will not. This is her Omega, her personal Omega. She cannot experiment on personal Omegas.
Simon seams to cool off. - ...Thank you...Be...tty?- He tried to remember her name.
- Yes! That's right, I AM Betty! What a Smart Omega you are! - she patted his head with awe.
- Wow! I need to check your IQ!
- IQ? - Simon was surprised. - But... This is not a very clever thing, remember your name...
- That's it! Omegas need time to adaptation and you already start to do this. Such a intelligent one!
Suddenly somebody almost stomped on them!
Betty shouted. - Hey! Look out! We are here, you stormy head!
The person looked around. - Oh, I am sorry, but Beniamin needs to calm down. - that was a tall Black women with dark curly hair. She was pretty. Her eyes was brown with long eyelashes.
Queenie.
Betty heart about her. She was a great ethymologist in The Centre.
But... Who was Beniamin?
- Your...Omega needs to cool off?
- Ah, no! Beniamin is a wasp.
Everybody jumped.
- WHAT?! WHY YOU ARE KEEPING A WASP HERE?! - Betty was shocked. - This is Omega's Centre, not Insect's!
- But...I am doing research on them! I need to have them in my room, you know?
- You...have insects in your room?! - Betty was shocked second time. - And no Omega?
- Of course not! I do not have time for that! - she snapped finger at this. - Insects are my family and they are the most important!
- You need to get Omega. Right now! - Betty grabbed her hand. - Queenie! We work in an Omega's Centre! Mr Glob will be furious at you! You need at least act like you are interested in them!
- But Mr Glob knows about my degree... And he let me work here.
- I know but... At least you should have Omega to distract you from your research.
- Well... That's not a bad idea...
- Super! So you should go and check some! Maybe you will find somebody to be worth your attention? I will tell Glob, do not worry! But go and check some Omegas!
Queenie was a little shocked. - O...okay? - she didn't want to go to the shelter. But a little break doesn't hurt, right?
- Great! - Betty was calmer now. Well, Queenie wasn't her great friend but she work in The Centre too. Betty doesn't want Glob to be mad at her.
- Go, go! I will have anything under Control here! Oh, and look at my Omega! Isn't he cute? - Betty grabbed Simon and scooted him to taller women. - His name is Simon! He Has a collar, is potty trained and everything!
- Ooookay...- Queenie was not unconvinced. - I still think that my insects are cuter. Keep my wasp Beniamin in mind. I do not have to keep it entertainment, it isn't very loud, i do not need to buy things for it... And it is easy to breed, you know? One queen and she laying a thousand eggs.
- Queenie...please! Insects are insects! Omega is your mate. This isn't The same! At least try to find somebody in The shelter.
- I am going there, i am going! But i do not know if Beniamin like it.
- GO!

...

Queenie opened the door to the shelter. - What a fuss about Omegas? They are just a lower Humans and need to have Alpha around them. Insects are more interesting. - She murmured. Why Betty pushed her so much? Well, her Simon was indeed cute and calm one, but Queenie cannot waste her time.
She stepped closer to the bunch of Omegas. There was so many of them! She didn't know how many people haven't got their Alphas. Such a cruel world...
She was looking for a calm and silent one. Somebody who will not interupt when she will study her insects.
No... Nobody here didn't match her expetations.
No...this one is not good either... Uhhhh! - Queenie wanted to give up. Why Betty was so happy about Simon?
And suddenly she saw something in corner of her eye.
One men was sitting completly calm and watched others. He was wearing glasses, Had long blonde curly hair and bread. He Has a metal crown on his head, why? Nobody knows, but it fitted the men.
He felt that somebody are watching him and titled his head.
Queenie saw the beautiful blue eyes and inteligent look.
Maybe he could be her Omega? He doesn't look to be hard to handle.
Let's try.
Queenie slowely go towards him.
The men wasn't reacting, only watched her like a scared dog.
- Shhhhh... Do not worry... I am not going to hurt you...- she started to treat him like one of her beloved insects. - It's going to be okay...
Then she saw that the men was watching... Beniamin. Oh! She forgot about it!
- It's not going to bite...i swear...or Sting. This is Beniamin, the wasp. Mine wasp. It's not agressive.
- Aaaaaaaaaaaaa! - The men shouted. - A wasp! Here is a wasp.
Well... Here we go...
Other Omegas Directed their heads to a Queenie and...
It created chaos.
Every Omega shouted and tried to hide far from her Beniamin.
- Ey! Beniamin is well trained! It's not gonna Sting anybody!
But it was too late. This one Omega scared all.
- Sh-&# - she cursed. - Beniamin is better trained than those Omegas. What a fool! - She reached for this men and clenched his ear. - See what you done! You should be ashamed of yourself! Bad Omega!
- B-but... This is a wasp! - He tried to defend himself. - Wasps are dangerous!
- Not this one! It's Beniamin! It is my wasp. I can communicate with insects and i am entomologist.
- E-entomologist? You like to be around insects? But... Bugs are creepy!
That's tears it!
How this Omega could said that awful things?!
She hit him in The butt like small child. - Stop it! Don't you dare saying something like this about my insects! You are not allowed to! Insects are better than humans!
She looked at him. She saw that he was having tears in his eyes. Oh now, maybe she was too harsh?
- Oh no, no! Don't cry! - she put the wasp on her pocket. - Sit here and be good. - she said to it and started to comfort Omega. - It's okay. The wasp is gone. What's your name? - she wanted to distract him.
- I am Kinger. I think. I do not remember my previous name. - he said slowely.
Queenie smiled. - Oh, so we are matching! My orginal name is Destiny, but everybody call me Queenie because of my job. I take care of my insects like a queen.
- That's...cute. - Kinger answered. - And... You are cute too...but without this insect! Wasp is not cute, not cute at all!
- Do you mind? Insects are cute living things! Do you know how many kinds of insects the world have?
- I...do not know and i do not want to know...
- The most of them are harmless! I can teach you! - Queenie wanted to change his mind about this.
She scrutinied him. Kinger was interesting. And his eyes! Such a beautiful color!
Maybe actually having an Omega is not that bad?
- I decided! I take you as my Omega! - she grabbed his Hand suddenly.
- Wait, WHAT? - he was shocked. - Me? - he was seeing her, she was beautiful, intelligent and the best women she ever saw. Why she choose him? He is a normal old guy. Nothing special.
Queenie fulfiled the formalities and grabbed Kinger on a leash.
- Well, now Betty cannot said to me that I am not interested in Omegas. - She said proudly.
- Betty? - Kinger titled his head. - Who is Betty?
- My coworker. We both Have a job in Omega's Centre and Tests.
He was terrifyed. Not there!
