A male omega.

You would think that no one would want one, Male omega's usually has a low infertility rate, even fucking them through their heat won't guarantee you a child, two heats won't guarantee you a child, they should've been ostracised by society, nothing but a genetic defect, something to just use a fuck toy, nature's freak but no, they couldn't do that, not to such beautiful creatures.

Male omegas are the peak of their species, not a single imperfection on their bodies, a slim, slender torso, a thin waist, big hips and big ass, thick thighs, soft feet, soft hands, soft everything, beautiful faces with eyes that look like gems, soft fluffy fair that can't be tamed, delectable scents that will literally make everyone drop on their knees, it isn't hard to see why they're treated like such royalty, even more when they are so rare!

Of course Izuku had to hide the fact that he's one- especially if he ever wants to stay in the army!

Male omegas, pampered by the riches of families, living their lives in luxury, they don't even have to walk a single step if their life if they so want- what kind of boring lifestyle is that?! No adventure, no fun?! No mud no getting dirty, everyone thinks you're the best thing to ever live on earth, no thanks, Izuku isn't into that! He wants to fight wars, help the country and their nation progress! He doesn't want to just have everyone else doing the work for him!

Alphas, Betas- all too emotionless, Alphas only care about fighting and war, getting their dicks wet and bathing in blood! Betas, too literal! Almost arrogant, middle class their ass they're cold blooded killers! They need someone who can think with their heart! Someone who can be empathetic- they can have some sense but everyone is too much of a slave to their instincts and biology- so Izuku, thankfully born from another omega who wants Izuku to have his own choice growing up, helped him hide his scent and stop his biology from overtaking fully.

With that, Izuku is probably the first ever omega with a built body, a smooth belly? No son, a build with 8 abs! 8! Arms thick and covered with muscles, so are his thighs, his ingrained flexibility and agility helps him too! A precise aim of the gun, almost as good as some betas! Doe adorable shining eyes? The only thing that shines within his eyes is pure danger!

In fact, although he's hiding behind the farce of a beta, he was almost always mistaken as an alpha although with a lot more common sense. In fact, with years of experience behind his back, he doesn't even need his scent blockers anymore, only when he's in heats and he goes back home for 'personal reasons'. He can swiftly hide his omegan side although he has to admit...

Being a male omega in the army has its perks and definitely gives him more advantage than anyone. Being an omega, it's a natural instinct to protect him, even if he mannerisms are different from most omegas, even if he's not built as one or even if he doesn't smell like one, the fact doesn't change that he's an omega and whether anyone has noticed it or not, they're all inclined to feel a bit more protective to him.

Kacchan who's all screams and anger and blood stops with a single scolding of the omega, he's confused, over why he immediately stops being angry and instead wants to calm this... beta? Calm this beta and fulfil all his wishes, it's weird and he doesn't like it but he's just forced to stop whenever the omega in secret tells him to stop.

Kirishima, kinda dumb, stupid as bricks, mostly doesn't think of his actions before doing them- whenever Izuku is around him, he suddenly feels like he has to think, he pauses and thinks before he moves, it took home awhile to notice but when he did, he was incredibly confused.

Shinso almost never sleeps aside from some small naps, he doesn't want to, there's so much else to do rather than just sleep? But when he's bunkering with Izuku, his eyelids fall too heavy to the soft sound of Izuku telling him that he needs to sleep, his mind unconsciously follows Izuku's demands and he doesn't know why?

Those are three out of many but the most major disadvantage in the army that Izuku has is definitely troubling.

Everyone thinks that they're inlove with him when really- it's just their biology reacting to a male omega!

What makes matters worse is that they're all so nice and charming to him- Izuku can't even choose a single person!

Then they started bringing up the topic of taking turns, Izuku refused to listen to what they have to say- no thanks! The moment he's outed as a male omega in the army, he'll be ripped away from them and he'd have to go live in a castle or something, yikes!

It's getting harder to shower alone, usually he showers in the dead of night where he knows no one is around aside from a Shinso sometimes but he doesn't suspect anything because of the scene and he's usually by the shooting racks anyways, but now, it's definitely getting harder and harder to shower, so much so he always have to take advantage of Shoto's constant invite to go Jacuzzi with him with only one condition and that he has to have only a bubble bath.

Shoto is always happy to see him splashing with bubbles in the tub although Shoto would definitely want to see him naked soon so he obviously has to form a plan.

He doesn't have to, Aizawa sensing the trouble just gets someone to build him his own room and shower, mostly because he sympathises as he knows Izuku is an omega since he's an omega in hiding too, and had the same trouble as him with his batch. God bless him.

It was all fine until one day, when there was a surprise attack at their base

"Oh, are you sure that not even a male omega can control you?!"

"You think that just because I'm an alpha I'll cave into my instincts?! It doesn't matter who they are, male or female, I won't be controlled by no one-!" The guy chokes and sputters before he collapsed on the floor.

Soon enough, everyone else was falling to the floor like flies, all equally confused, 1st over why they're on the floor and 2nd, why omega pheromones flooded the room even though there's not a single on in their ranks who is an omega-

"What's wrong? I thought no kind of omega, even a male omega can control you?" Izuku's small smile morphs into a smug grin at the alpha on his knees right, now, "got anything to say?"

"Y-You- what the fuck is a male omega doing in the army-?!" The guy wrenches as his hands instinctively cover their mouth and they're filled with shame.

"That's right, you don't talk to your prince like that. Now take your little group out and leave- and if I hear one thing about me from outside, I swear to god I will find you and I will make you kneel before me. Go." Izuku hisses and the intruders scramble to get away.

He was felt with such smugness and pride, he never knew being a male omega could be so satisfying! Getting someone to follow your every whim is amazing! Now he knows why male omegas just like having stuff done for them, this is amazing-

"D-Deku? You're an omega?" Katsuki chokes out, Izuku pauses.

Ah shit.
