Author's Note:
After some deliberation, I've made this pre-story. The main plot points begin in Chapter Two: Ω. I had initially intended on a different direction but changed my mind.

Bottom Line: For faster action, skip to chapter 2

Explanation of omegaverse (if you know about this common manga concept please skip over the next few paragraphs):

There are three types: Alpha, beta and omega.

Omegas are the most fertile (be it male or female they can both become pregnant). They let out a pheromone that attracts mates. Though some betas are influenced by these pheromones, they are particularly effective on alphas. Once a month omegas experience their 'heat' a time of month where their bodies go into mating mode.

Betas are the most common type; they can mate and reproduce through male x female reproduction.

Alphas are the least fertile and are known to be the most successful in life. They are naturally talented, strong and can usually be found in higher positions of power (CEOs, judges etc.). Many alpha families marry into each other to keep the alpha lineage, and many do not like omegas as they release their pheromones and distract them or unknowingly force a 'bond.' The opposite is true as well where some alphas love the idea of having an omega.

"All right boys and girls. As your recently transferred high school principal, it is my responsibility to inform the grade 10 students of South Park high that tomorrow will be your type testing day. All students will be visiting with the doctor throughout the day to receive their typing and the consequent health concerns regarding each. Following will be an information session in the school auditorium where attendance will be mandatory. Thank you!" PC principal's voice strolled through the end of day announcements.

"My sister said they have to take your blood with a needle." Stan said.

"Needles?" Kenny asked nervously.

"At least we'll get to miss some classes. But the information session seems like a waste of time." Stan shrugged.

"Yeah, everyone knows already that alphas and betas are normal. They should just have the omega students go." Cartman complained.

"What do you guys think you're going to be?" Kenny asked excitedly.

"I'm gonna be an alpha for sure! I was looking at myself in the mirror the other day and I looked pretty ripped." Eric was the first one to reply.

"Sure you are fat ass. You'd better hope you're not an omega, no one would want you!" Kyle teased.

"I'd be much better than a ginger Jew." He shrugged easily.

"Shut the fuck up fat boy!"

"Just saying." He sighed, happy to have gotten under his skin. It was just too easy. "Besides, Kenny's going to be an omega anyway just like his mom." Cartman began to snicker.

"Am not!" Kenny retorted, though he looked a bit nervous.

"Everyone knows you're either what your mom or dad are. And your mom's an omega and your dads a beta. Best case you're still a beta!"

"You'll be fine Kenny, don't listen to him." Stan reassured his nervous friend.

"If you're really nice to me Kenny I'll make you a part of my harem. That way you won't be so poor anymore." Cartman laughed loudly again.

"Oh my god, guys, were here!" Turning around just after the front doors to the arcade Eric looked each of them in the eyes.

"There's a reason I brought you all here today. We're after one thing and one thing only." Cartman steepled his fingers together. Despite being in the 10th grade now, he pointed up to a Clyde frog with a pink bow in the top.

"Mrs. Clyde Frog will be mine by the end of the day. Only play the games you're best at. Here are your allotted tokens. Here, there you go." Cartman handed out the tokens to each of his three friends.

"Now gentleman, I'm counting on you. For the love of me – you'd better not waste those tokens. Godspeed. We'll meet back here at 1800 hours."

Kenny went off with Eric, heading for the zombie shooter they loved so much.

"Lets hit up street fighter." Stan started leading the way and Kyle followed.

20 minutes in, Stan had gotten a long row of tickets from his run on street fighter.

"My turn now." Cracking his fingers, Kyle easily passed the first few fights and kept selecting to bet all his tickets get a bigger pot the next round. When he got to the 8th round - the one Stan had failed - Kyle's finger hovered over the 'bet all' option.

"Dude, no way, you're going to loose all your tickets."

"I'm fine Stan. This will be no problem." Selecting all or nothing he took a deep breath.

Pushing up his sleeves he slammed the joystick furiously mashing the buttons and performing nearly perfect combos.

"Omg dude! You're going to do it! No way!" Stan was watching wide-eyed, cheering on his friend from the sideline.

Kyle felt his palms begin to get sweaty. Biting his lip, his tongue sticking out in concentration he readied his special attack.

The computer attacker also did the same. He activated first, his attack travelling horizontally across the screen. Kyle put in the commands to jump, but as he went to flick the joystick up, his hand glided right off the top.

"What!? No!" Kyle slapped a palm to his forehead as he watched helplessly as his avatar got obliterated. "I jumped! I totally jumped!"

"Well... that sucks." Stan shook his head, taking the one ticket out from the machine that he'd gotten as a consolation.

"You've got to be kidding me." With a groan he looked at the measly ticket. Already he could hear Cartman bitching at him.

Easily seeing how upset he was, Stan spoke up,

"Here, I got an idea. Follow me."

He led Kyle through the flashing lights and machines until he reached a small one in the corner.

"There's a big chance you'll loose the ticket completely, but there's also the chance to win more and get something substantial." Stan explained.

"I only have the one ticket though." Kyle said, still reeling from his loss.

"What's the point in giving just one ticket?"

Stan was right, but with the luck he'd had lately, he was going to have to go back empty handed.

"Sure. I'll just go ahead and put it in."

Slipping the sole ticket in, a ball launched out, bouncing around different holes. Kyle closed his eyes, unable to look.

'Please, please give me something.' He hoped in his head.

"Kyle... look at this."

"What..!?" Looking through the plastic bubble, the ball got stuck on top of a wall, hovering just by 100 tickets and 0 tickets.

"Oh my god... it's just sitting there. Should we hit it?" Kyle asked, his hand reaching to the right side of the machine.

"Wait. Hit it here." Stopping Kyle, Stan gave a swift smack to the left side of the machine. The ball teetered and rolled towards the 100 tickets. Then it rolled back. It hovered on the edge, threatening to plunge into the 0 tickets hole. The two boys sucked in a breath and watched at it settled back on the wall.

"Okay... plan B." Stan knelt down, looking around to make sure there were no employees around before sneaking his fingers beneath the entire machine. He lifted it, tilting it just enough for the ball to fall into the 100 tickets slot.

"You did it Stan! I owe you big time!" Kyle grabbed Stan in for a hug, grinning from ear to ear as the tickets began to fly out.

"Just in time too." He grinned, "We're meeting back by guitar hero. You ready to go?"

Once the two boys returned they saw Cartman yelling at Kenny.

"I should have known better than to ask a poor person. I bet you don't even have an Xbox at home do you?" He growled, upset.

"Fuck off!" He retorted, his voice muffled by his jacket.

"This is what I'd expect of an omega." Eric stated matter-of-factly.

"Stan! Kyle! Tell me you guys did better than Kenny can't-play-for-shit-McCormack!"

"Don't worry, we've got more than enough to cover Kenny." Stan grinned as he and Kyle held up their huge stack of tickets. Kenny glowered in the back.

"Ooooh hell yes!"

Cartman grabbed the pile of tickets, getting them counted and promptly choosing Ms. Clyde Frog from amongst the prizes.

"Oh. Mah. God. This is gonna be awesome!"

"I can't believe you still keep your stuffed animals." Kyle said, shaking his head.

"Clyde Frog is special, Kyle. You wouldn't understand." Eric said coolly.

"How about you give us the leftover tickets." Stan said, knowing there were still a lot of points leftover.

"Hmmmm."

"Come on, we got most of the tickets, we just want to get candy and shit." Stan prodded.

"I guess that's fine." He shrugged, much too happy about his new stuffed toy addition to be particularly selfish.

Filling their pockets with sweet treats, the four boys walked out, happily munching. The sun was just beginning to slide down into the horizon.

It had been a good day - or at least that's what Kyle thought. They talked and joked about nothing in particular.

He briefly wondered if anything would change after tomorrow.

"What's up Kyle, why are you walking so slow?" Stan asked. The other looked back at him expectantly.

"No... it's nothing."

"Hurry up then. I want to play that new PlayStation game with you guys."

"Yeah." With a fond smile Kyle hurried to catch up.

"Mrs. Garret's class, please report down to the school gymnasium. Thank you." PC principal's voice alerted over the intercom.

"Alright boys and girls, please line up. You can leave anything in the class as I'll be locking the door."

There was a nervous energy in the room as everyone stirred, getting into a haphazard line.

"Hey Kenny, how are you?" Kyle asked, seeing his friends pale face.

"I'm just not... good with needles."

As they walked through the hallway Kyle whispered to him, trying to ignore the sweet smell drifting in the hallway.

"Look, don't be nervous about what Cartman said. I'm sure you're not going to be an omega. Even if you are, there are lots of people who aren't complete assholes like him and won't judge you on your type."

He mumbled something unintelligible under his hood, but before Kyle could ask what, he heard his teacher's voice.

"Excuse me, you should be in class right now."

"Yeah, yeah."

"Who's class do you have right now?"

"...Mr. Brown's." He sighed.

"Good, it's just down the hall. I'll watch until you're back."

With a grunt the kid dragged his feet. Kyle peeked out of the line. He'd first met him when he was the leader of the sixth graders, only now he was leader of the 12th graders.

"Look at all the little ducks all lined up to see what's in store for their future." He walked past the students, staring at each of them in turn.

When his gaze turned to Kyle and Kenny, they pressed themselves closer against each other. Kyle's eyes met his piercing gaze and he kept his eyes for a few moments. He glared, happy to continue moving down the hallway.

"Do you smell that?" He heard Kenny ask.

"That sweet smell? It's faint, but yeah I smell it." Kyle agreed, shaking off the goosebumps from his stare down.

"I wonder if they'll have cookies after school again..." Kenny wondered

"Gonna try and get some of the failed attempts again?"

"Fuck yeah. I don't know why more people don't do it. Normally they give hem away because they don't look good. They're not even burnt or anything!"

"Okay students, please have a seat, they'll call you in a few at a time. Please be patient. When you've finished you can head on up into the seats of the auditorium."

Kyle and Kenny talked as they waited, becoming more nervous as they saw the broad smiles, the looks of indifference and the downtrodden ones.

"Broflovski, Kyle."

A nurse poked her head out from on of the temporary offices.

With a sharp breath in, Kyle marched ahead, wishing Kenny good luck.

Stepping in, the nurse gestured to the seat.

"I'll need you to take off your jacket and roll up your shirt's sleeve."

Kyle did as she said, removing his jacket, sitting quietly in the chair, his feet fidgeting.

After taking his blood pressure she prepared the needle.

"Don't be nervous," she washed his arm with an alcohol swab, the coolness making him even more jittery. "It'll just feel like a little prick. You can look away if you'd like."

"Make your hand into a fist."

Tying a band around his arms, Kyle could see his veins bulge up. The needle slid through his skin easily, slowly drawing out red.

And just like that it was done.

"Hold this cotton here."

He did as told while she placed a band-aid atop the gauze.

"Just sit here and I'll have your results in a few minutes."

She put his blood into a machine, examining a few things before she printed out a sheet.

"Okay! I've updated your information in our systems. Congratulations." She turned over his sheet with a smile.

"Is this right..? Is there some kind of mistake?"

"Not at all. The machine does all the work."

"I think... this is wrong.. .can... can I try it again?"

"I don't see why. You'd just get the same result." She looked puzzled.

"Well here's an information package on your typing. Be sure to read it thoroughly." She stood up gesturing for Kyle to do the same.

"I have a few questions." He said hurriedly.

"Sorry, I wish I could answer them. I'm just here to do the typing though. There's the information session afterwards. I'm sure a lot of your questions will be answered through that. If you have any further questions you can make an appointment with your family doctor."

He suddenly felt faint.

"Are you okay? You're looking a little pale."

"I'm... I'm fine." He stuffed the papers in his jacket pocket.

A smile grew on his lips as he walked from the temporary offices, hearing Kenny's name being called. He waved to his friend, giving a thumbs-up as he disappeared into the office.

He found his way to the bleachers in the gym, finding a seat high up.

He wondered why type Kenny was. He wanted to talk to him. His heart thudded loudly in his chest. When he saw him leave the tent he waved. Kenny saw him in a moment and ran over to him.

"Kyle! It's great Kyle! I'm a beta! Whoo hoo!" Barely able to contain himself he waved out to Stan and Cartman who were also entering the gym.

"Guys up here!"

Kyle smiled and waved at them as they settled down beside each other.

"How'd it go?" Stan asked.

"You going to be taking it up the ass Kyenny?" Cartman hunkered down next to the boys.

"Shut it fat ass, I'm a beta! How about you?"

"I already told you guys yesterday, I'm an alpha." He said smugly, crossing his arms over his chest, revealing a shirt already with the alpha sign upon it.

"C'mon dude, stop lying, you're not an alpha." Stan rolled his eyes.

"Am too!"

"Show us your results then." Stan pushed back.

"It's in my backpack. But here, take a sniff of my pheromones. You'll know a natural born leader by his smell." Cartman lifted his arm, inching his armpit towards Stan.

"How convenient." Stan shoved their loud friend away from him, scrunching his nose in disgust.

"I'm an beta too Kenny. I think it's best since we don't have to worry about all the alpha, omega crap."

"Hell yeah. What about you Kyle?"

"Me? I'm a beta too." He shrugged.

"Awee laaame. No one's an omega? You know I hear one of the girls from our class in elementary school is. I wonder who." Eric mused.

"You sound really gross right now Cartman." Stan said, "Especially since you're an alpha."

"Huh, nah man, it's natural. Omegas are gonna flock to me, you'll see. Now what the hell is that smell? It smells like those home ec kids are making something good. Kenny! Let's check it out after!"

"Good afternoon everyone in grade 10, how are you all doing today?... GODDAMIT! Lesley! Shut the fuck up!"

"Okay, now that I have your attention, I know a lot of you are probably surprised by your results and concerned about types. I just want to get this out on the table right now. No one type is better than the others okay? We're all just people and we should all treat each other with dignity and respect.

That being said, there are certain physical differences that can be of concern. Your typing is just like a second puberty. You'll experience changes in your bodies that are not bad, but that are perfectly natural. For alphas it will become more difficult to make a baby when you're older. For omegas it will be much easier. That's why omegas should be extra careful if you are to engage in sexual relations. I don't believe that it should be happening when you are all this young, but IF you decide to, you'd better do it safely, and always make sure to have your partners consent!

To the alphas, some of the omega students may smell really good to you, but that does not mean that they are okay with you touching them. For everyone - not just the alphas and the omegas - you must always have affirmative consent - I cannot stress this enough.

For both boy and girl omegas it is possible to become pregnant through unprotected intercourse. You will also experience heats. For these there are pheromone suppressants that will be available to you through the school nurse. Please make an appointment when it becomes pertinent in your daily life." PC principal continued on, stopping to ridicule students who made faces at what he was addressing.

"Man that sucks for them." Stan whispered.

"As if, omegas have it easy. All they have to do is spread their legs for some rich alpha and pop out a few babies, then they're set for life. It's alphas that have to do all the hard work." Eric complained.

"Eric Cartman! Shut it! As I was saying, once omegas start their heat it is recommended by doctors to wear a neck protector so that an alpha doesn't bond with you through a bite to the neck. Though all alphas should be in control of themselves, there have been cases where an omega has been bonded against their will. This is irreversible, so please protect yourself."

After the rest of PC principal's speech, Stan nudged him, "You've been quiet Kyle, are you okay?"

"Yeah! Just tired. I was nervous about the tests so I didn't sleep that well."

"Well, you're normal like most of the rest of us." He shot a look at Cartman, showing his doubts that their friend was telling the truth.

"Yeah." Kyle felt Stan's reassuring hand on his shoulder, but suddenly that hand felt very far away from him.

Once home he grabbed the papers from his pocket, crumpled from the stress of his fist.

Slouching into his computer chair he stared at the results before him, his stomach twisting nervously.

'Omega...? I'm an... omega..?'
