"Thank you! Have a good night!" Izuku called to the nice storeowner lady whom he came to enjoy since she was so nice and kind to him. He really appreciated the old lady since she understood that he was a young Omega just trying to get through his life without conflict with others, specifically Alphas.

He had been doing good and nothing bad had happened in a long time, the last time he could recall that turned bad was when an old childhood friend of his humiliated him. Ever since then, Izuku did his best to just mind his own business.

The greenette made his way down the street after checking his phone for the time. 10:24pm. He really didn't want to have to come out so late, but he got out late from his job at the small flower shop since he had to close and check some things, and he needed some things for his apartment as well. With a sigh, Izuku tucked his phone into his pocket with one hand while the other held his bag of groceries, continuing to walk to his apartment not too far from here.

However, after passing one of the many alleyways down this particular street, he feels something off and though his instincts tell him to look behind him, he started walking a little faster to see if he could try to avoid whatever he wasn't liking. Then, even as he walks faster, further dread fills his bones and he's forced to look back when his instincts were literally screaming at him now.

Four tall men in dark clothes were now trailing after him too close for his comfort, not to mention they all smelled like Alphas and looked obviously suspicious. Izuku hopes that he was just reading too far into this and he turns back forward and continues to walk fast. The hair on the back of his neck raises when he feels like they're too close now but then a hand suddenly wraps around his wrist and he's pulled back into another alleyway then he's surrounded by all four Alphas.

His eyes widen in fear and he tries to get away from them but they block his exit and let out growls.

"Don't leave so soon, Omega~" one of the Alphas said with a dangerously low voice, making Izuku further on edge.

"This is all I have, really. You can have it," Izuku offers, hoping they were simply after money and not something else of his. He swallows nervously as one of them yanks his grocery bag out of his hand only to toss it aside, he immediately feels horror fill his blood. Not even needing the Alpha's next words to know what they were after.

"We don't care about your groceries, the only thing we want right now is a nice, obedient, virgin Omega, and you're a perfect candidate~" another purred just as all four Alphas released their scents to try and seduce the green haired Omega forcefully, but he grits his teeth and clenches his fists, deciding that he's not going to go down without a fight.

Izuku bares his small Omegan fangs and his light scent turned sour with hostility. He lets out a threatening growl and doesn't look affected by their scents swirling around him. "Don't think your scents will effect me, you all smell horrible, and I'm not going down without a fight."

This didn't seem to fit well with the four and they begin to lay their hands on Izuku as they tried to restrain him but the Omega outwits their attempt and with tight fists, he lands a solid punch to one Alpha, then a swinging kick to another, and dodging the other two who lunged for him. He may not be as big as these Alphas, but he was sure to train himself so he could fight and defend himself, hiding a decently fit and muscular body under the t-shirt and sweats/short he usually wore.

Izuku slipped away from where he had been cornered and with fists in front of him ready for battle, he faces the four Alphas once more as they still blocked his way out of this alleyway. He even smirks, feeling rather eager to give these nasty Alphas some karma for free, but ultimately aimed to escape so nothing bad could have a possibility of turning up.

One dashes towards him directly and he swiftly sidesteps before bolting forward towards the other three, planning on bypassing them as they would attack and lunge for him. He manages to dodge the second one who tried to grab him with his whole body, but the other two Alphas were able to snag his arms before he could pass and escape.

They quickly pulled Izuku back and slammed him into the ground, a grunt of pain erupting from him and the wind is knocked from his lungs, stunning him long enough for the other two Alphas to rejoin and hoist Izuku up onto his knees but keeping him from trying to rise up to his feet. The presumable leader of the group grins widely and huffs, grabbing the freckled male's chin harshly and forces him to look up at him.

"We like an Omega who fights back, gives us the thrill of a hunt~" he says in a smooth voice, his eyes glinted with desire and malicious intent. The other Alphas could be heard chuckling and purring into Izuku's ear who felt disgusted by the group and what they wanted to do to him.

Izuku now tries to break free from the four but finds his limbs being held down tightly and his heart plummeted in his chest, his determination to get away melted into fear, even more so when he hears the Alpha in front of him begin to loosen his belt and heard the shuffling of his clothes.

The leader Alpha then decides to play with the greenette some more now and wraps his hand around his throat before squeezing. Izuku yelps and struggles to get air into his lungs that started to burn, his face turning pale and he tries to thrash to get away so he could breathe.

Then, the scent of the Omega took a drastic turn and the Alphas seem to notice this as they flinch slightly, but the leader narrows his eyes and tighten his grip around his throat, not showing any signs of letting go.

Izuku's emerald-green eyes turned dark and his pupils became thin slits, fury and bloodlust filled the dark green pools as his deadly glare turned to the Alpha choking him. The Alpha flinches slightly and that's all the opening the freckled male needs to whip his head back to free his neck, then harshly throws his right fist to the leader Alpha's face, immediately breaking his nose as blood stained his knuckles.

"Damn Omega—!" the Alpha who held the arm that was used to punch the other one grunts, growling in frustration as he tried to control the Omega but he now thrashed with more strength than he and the other anticipated, causing their grips to loosen or drop off completely.

The group of Alphas now realize, especially the one with the broken, bleeding nose, that the Omega before them that they planned on having fun with now turned feral. And nothing was more dangerous than a feral Omega.

The reason why feral Omegas were so dangerous, most times more dangerous than feral Alphas, is because while feral Alphas could be soothed by their mated Omega's scent and could actually be talked to and reasoned with as they can talk themselves, feral Omegas reverted completely back to their primal stages and listened to and trusted no one other than their own direct kin. They understood no human speech, weren't affected by scents of Alphas, Betas, or even their mate's, they were hostile to every person that isn't kin, and are easily spooked which results in them being provoked and them attacking with extended claws and fangs. The amount of time an Omega remains feral all depends on the severity of the situation they were in before going feral, and depends on their environment; if they are left alone and don't feel threatened, it usually only takes about 1-3 hours before they return to normal however, if they are stressed and feel threatened, they can remain feral for days, or for however long they feel unsafe.

Izuku doesn't give the Alphas a chance to flee or fight, already breaking free forcefully from their holds and sinking his teeth into one of their legs, biting down hard and enough to snap the bone into splinters and shards within the body, spilling blood instantly alongside it.

The injured Alpha screams out in pain and tumbles to the ground, the other two still close to the feral Omega try to restrain him again but each made a poor choice.

The greenette turns to the one closest to him and delivers a harsh headbutt, clashing their foreheads this hard together knocks the Alpha falling back but the Omega remains up and turns to the last, uninjured one. He tightens the muscles in his hand and fingers and slashes the Alpha directly in the face, blood splattering on the concrete ground as the Alpha is now falling back too but blinded. However, the feral Omega wasn't even close to being done.

Izuku, now free, rises to his feet and with a lot more strength than the Alphas previously thought, he grabs the one he just slashed by his hair and slams his body down on the one he had bit, easily lifting and throwing the Alpha down like he weighed nothing.

He turns his murderous glare to the Alpha he had headbutted who was now recovering, looming over him and before they can do anything, he grabs his hair too but doesn't lift him up. In fact, Izuku quickly yanks the Alpha's head towards himself but downwards to meet his rapidly rising knee which results in a loud crack to fill the dark alleyway. He drops the now unconscious Alpha to the ground and faces the leader with his long fangs bared and blood of the other Alpha's staining his face, snarling and growling dangerously.

The broken-nosed Alpha tries to back away and flee, but Izuku is much quicker and catches up to him. He goes for a low sweeping move and swings his leg low to trip the Alpha. Said Alpha comes falling to the ground and Izuku pounces on top of them to deliver another blow only for a sharp pain to bloom in his midsection.

Looking down, the feral Omega sees the Alpha plunge a piece of glass into his abdomen, blood seeping out from his deep wound and though he doesn't register pain in his feral mind, his body certainly feels it and he's unable to move for some seconds. The Alpha smirks widely and shoves Izuku off, sitting up and pinning him down after tossing the Omega onto his stomach, ignoring how the shard of glass dug deeper into the smaller male's abdomen.

The leader Alpha decides that he'll have to keep Izuku in order to properly punish him later, so he decides to try and mark the Omega so he would have no other choice but to obey him. He leans down and exposes both his own fangs and the freckled male's scent gland placed on the side of his neck, growing close and grazing his sharp teeth against the other's unmarked gland.

Suddenly, Izuku jerks back sharply and to the side to avoid being marked at all costs, having recovered from being stunned after being stabbed by the piece of glass still in his body. He seems to have hit the Alpha when he threw his head back so he flips himself over, feeling the strength in his body begin to fade, and with the same bloodstained claws, he slashes at the Alpha's throat and relishes the feeling of his claws digging into soft flesh and cutting off vitals from his attacker.

The final Alpha's body goes limp and eventually falls over onto the ground of the alleyway, joining the other Alpha bodies on the cold concrete. The thick smell of blood hung heavy in the darkness, overpowering the distressed scent of feral Omega and even the potent scent of Alpha.

The green haired Omega then feels something was off, and a strong burning feeling came from his scent gland that the Alpha had tried to mark. He lifts his non-bloody hand to his neck and feels it only for him to withdraw his hand immediately and hiss in pain, his eyes then widened when he saw blood staining his hand that felt his scent gland. He didn't know what exactly happened to his neck for it to be this bloody, since he now noticed how blood was spilling down from said gland, cascading freely like a waterfall and he feared his jugular had been torn open when he jerked his head and neck away. However, that wasn't his focus right now as he's able to think a little bit at the moment.

Izuku felt dizziness and fatigue wash over him as he slowly exits his feral state due to his severe wounds and he's unable to stand up, so he just tries to crawl and drag himself out of the alleyway so he could get some help after finding his phone cracked still in his pocket. The Omega weakly and shakily crawls closer and closer to the entrance of the alleyway, and just when he sees someone come into view and reach down to him, their mouth moving but no noise reached his ears, darkness swallows him whole and he goes unconscious in a pool of his own blood with it trailing after him from where he was initially stabbed.

"Deku......?"

A/N: Just a little thing I had in my head that I couldn't stop thinking about. I may expand this some other time, but for now, it shall remain at this. I apologize if it sounds a lot like some of my other stories, I honestly don't intend it but it just happens, lol ówò
