Izuku and Shoto were stunned. All Might had a child?! How could no one know that?! The tiny Omega was being scented all over by the frantic Toshinori and being the boy's mother was probably the only reason Katsuki wasn't freaking out. But that changed the moment a paramedic touched him, the Omega letting out a piercing shriek.

With a furious snarl, Katsuki lunged, pinning down the paramedic, gaze livid. "Don't. Touch. My. Mate!" The Alpha ground out, explosions sparking on his hands.

"Alpha!"

Head snapping up, Katsuki set his gaze on another paramedic. Omega, his nose told him, and one who was mated.

"I apologise, Alpha…my comrade is a Beta…He didn't know he shouldn't touch your mate. If you allow, I will examine him." She kept her hands up, never moving. Eventually Katsuki let go of the Beta and backed off. With a relieved breath, she nodded her thanks and turned to Atem. "Heya…My name's Isabella…are you okay with me examining you?"

Atem, who was still pressed into his mother, nodded. He was okay with the Omega, but he didn't want a Beta touching him.

"Good, good…Alpha, is there anything I need to know in regard to your Omega?"

Katsuki knew this was about to cause a hell of a stir. From the looks of things behind him, all of 1-A had gathered alongside Izuku and Shoto, confused gazes on Toshinori holding Atem. If any were surprised by the paramedic referring to Atem as his Omega, they were good at hiding it. "Eh yeah…Atem's pregnant…Almost two weeks."

"Are you serious?!"

Jerking around at the furious cry, Katsuki set his gaze on a very pissed off Mineta. "You got a problem there, trashcan?"

"We've been working around the clock to find your dumb ass!" Mineta lisped irately. "And you've been hidden away with some whore and getting him pregnant?!"

Atem flinched at the callous words and his emotions filtered over his link to Katsuki. He waited for his Alpha to attack, but the brash teen kept himself in check by sheer force of will.

"What is going on? I ordered you all to—" Coming to an abrupt stop, Endeavour's eyes settled on the Omega, surprised to see him clinging to Toshinori and when the boy's scent finally filled his nose, he jerked as if he were struck.

"Dad?" Shoto enquired. "You've gone snow white."

It wasn't possible! Counting back in his head, calculating dates, Endeavour almost dried heaved out of sheer shock. The night he and Toshinori were trapped underground and Toshinori had gone into heat…it had taken three days to free them and in that time both of them had lost control. They had swore they'd never speak of it…but…damn it…how could Toshinori hide the fact he had ended up pregnant with his child?!

"You got pregnant?!" He barked before he could stop himself. "Why the hell didn't you tell me Toshi?!"

Toshinori moved Atem behind him, blue eyes narrowed. "You were furious over what happened…we had ended up in a situation neither of us were supposed to and I promised I'd never bring it up again. But don't you dare stand there all haughty and act like I never tried to tell you…I did, Enji! Numerous times! But you kept dismissing me and the fact that your own damn nose didn't pick it up? Well, that's on you."

"Wait!" Shoto croaked, bicoloured eyes darting back and forth between his father and All Might. "You…You had an affair? He…He's my brother?!"

"It wasn't like that!" Endeavour barked, eyes awash with numerous emotions and very much aware of their peanut gallery. "We were on a mission…Damn villains everywhere and during a rescue…the street collapsed from beneath us. We were trapped on all sides and with no idea how much oxygen we had, or how to safely remove the debris, we had to depend on others to get to us. Unfortunately, fucked up timing led to Toshinori going into Heat and triggering my rut. We tried to stay away from each other, but instinct won out. If my count is right, the boy is six or seven months younger than Shoto."

Toshinori nodded. "He was born in July and his name is Atem."

A mix of hurt shock and fury wiggled about inside Shoto. It was neither of their faults by the sound of it, but he couldn't help how he felt.

Isabella used the lull in conversation to finally examine Atem. The Omega was dead on his feet, clearly in desperate need of rest and could have done without the drama. Getting to work, she took vitals, a blood sample and checked his temperature. The entire time, she could feel Katsuki's gaze burning into the back of her head and made damn sure she didn't touch him anywhere Katsuki's instincts would deem a problem. Such as the healing mating bite upon the teenager's throat.

Atem paid little heed to what the paramedic was doing. No. He was just still a little stunned to learn finally who his Alpha parent was. The boy who called him Dad didn't appear happy and from the sounds of the mess that had occurred, he could understand why. That would mean his father's mate had to be a beta. After all, once an Alpha and Omega mated, pheromones no longer affected them.

"Are you okay?"

Startled, Atem looked up at Katsuki and smiled. "Yes. Today's just been a lot. Honestly, I just want to curl up and sleep."

"So, you're my little brother."

Startled, Atem lifted his gaze to where a boy his age hovered. Red and white hair framing a scarred face. His expression was hard and cold, it made Atem wary, and his fear filtered through to his Alpha.

"Careful icy-hot," Katsuki warned. "This shit isn't his fault."

Shoto jerked back at the sound of a snarl and blinked at the sight of a panther made of black fire nudging him back, before plopping in front of Atem and Katsuki, baring his teeth in warning.

"Easy, Anubis," Atem warned gently, before settling his gaze on Shoto. "I guess so…if that's going to be a problem, can we talk about it when I haven't been held captive for eight years."

"WHAT?!"

Jumping, Atem scrambled back on the gurney, looking at the furious Endeavour marching toward them. Anubis was immediately on alert, fire blazing along his back.

"Calm down, Enji!" Toshinori snapped.

"Calm down? Calm down?! Eight years! Not only do I have another child, but he was captured for eight years?!" Endeavour demanded, fire pulsing along his body. "Did you even bother to look for him?!"

Blue eyes widening, Toshinori let out a sound that could only be called a snarl. "I tried everything to find him! Called in every favour and for every day I couldn't find him, it damn near killed me! So don't you dare come at me with your rage."

When the tears fell, Enji's temper drained. His Alpha instincts could never tolerate an Omega crying and Atem's scent had soured horribly. His pup was terrified of him.

"Enough!" Isabella barked; the paramedic fed up. "Endeavour, your pup is pregnant, and this stress is doing him no good! Now, from what I can see, he's completely fine. He just needs rest, as does his Alpha. So can everyone stow the temper tantrums until later!"

Properly scolded, everyone backed off and while part of the team dealt with lose ends, Atem and Katsuki were brought back to U.A to rest. Anything else, could wait for the morning.

Waking was a new experience when sunlight flooded in through a set of balcony windows and from outside the door, Atem could hear the happy voices of others. After so long on his own, with nothing but concrete walls, Atem was elated.

Scrambling over Katsuki, the Alpha grunting in his sleep, the Omega opened the door and hurried out, Anubis right on his heels.

Following the voices, he found all the faces he had seen the night before in the kitchen preparing breakfast. He recognised his brother setting the table, the Alpha speaking to the male Omega Izuku. But the others, he didn't know the names of.

"Good morning!" Jumping at the boisterous greeting, Atem turned to face another Alpha approaching him, smiling warmly. "My name is Tenya Iida! I hope you slept well!"

"I uh…did, thank you," Atem returned politely.

"You are such an adorable Omega!"

Startled by a bubbly girl with pink skin, Atem smiled shyly. "Thank you." She was an Omega also, he realised. In fact, his nose told him 1-A possessed four Alphas and two Omegas. The rest were Betas and though they seemed nice, their scents made him nervous.

Which was probably why there was a sudden crash from upstairs and Katsuki's furious bellow filled the dorm, a moment before the Alpha vaulted over the staircase and dropped down to the first floor.

"What the hell?!" Mineta spluttered, almost trampled when Katsuki lunged straight for Atem and began scenting him all over. "Jeez! Could you two keep a lid on that crap?! This isn't a brothel!"

"Mineta!" Izuku snapped, green eyes flashing with temper. "Knock it off!"

"Yeah, dude," Kaminari said with a frown. "What's crawled up your ass? He okay Bakubro?"

Nuzzling Atem's throat, feeling the Omega calm across their bond, he pressed an affectionate kiss to his temple and glanced at Kaminari. "He's good…but Betas make him nervous and there's a lot of you here."

"Makes sense," Izuku said, smiling gently at Atem. "Betas held you against your will. So, can I ask you something?" Atem nodded, at ease with the other Omega. "Is he your Quirk?"

Looking down at Anubis, Atem smiled. "Sort of. My Quirk is called Shadow Flame. I create shadow fire that burns hotter then regular fire. But the main thing I can do with it, is create sentient creatures. It takes concentration to hold them, but Anubis is different. He appeared the same day as my Quirk manifested, just a cub and grew with me."

"Like Dark Shadow!" Izuku gushed.

Atem nodded. "Katsuki told me about Dark Shadow, Anubis is similar. He functions on his own, but still answers to me."

"Hungry?" Katsuki asked, kissing his cheek, which only succeeded in making the girls gush.

Atem nodded. "A little."

"Gotta feed the parasite," Mineta ground out snidely.

No one saw Katsuki move, but a split second later, Mineta was slammed into the wall, a vicious snarl ripping from the brash Alpha.

"Kacchan! Don't!" Izuku shouted, trying to come between them. "He's not worth it!"

"He's been running his mouth since yesterday!" Katsuki snapped. "Making snide remarks at my mate and now my unborn pup? He's roadkill!"

"Katsuki." Going still, Katsuki's gaze slid toward Atem, his hand set gently on his bicep. "It's okay…I don't care what he has to say. Let him go, please Alpha."

Temper dissipating, Katsuki let Mineta drop with a grunt. The purple haired bastard hitting the ground with an audible thump. Bending to nuzzle Atem, he chuckled lowly. "Clever little shit."

Atem grinned. "Nothing talks down an Alpha faster than their Omega."

"Sit down, baby, gonna make you something good."

Trembling, Mineta watched Katsuki head into the kitchen. Izuku glared down at him. "Damn it Mineta, Atem has done nothing to you, and you must be suicidal to insult an Omega with their Alpha next to them!"

"What would you know about it?!" Mineta snapped, furious now and attempting to save face. "All muscled like that, what Alpha would have you?!"

Colour draining from his face, Izuku jerked back as if slapped. Tears welling, he tried to form a response, but when nothing came, he rushed out.

"Mineta, you're such a jerk!" Mina spat.

"I agree," Tenya growled out. "That was completely uncalled for."

With the others dealing with Mineta, enraged by the insensitive cruelty the Beta threw at him, Shoto followed Izuku and found him not far from the dorm, shaking with sobs.

"Midoriya?"

Stiffening, Izuku looked back, wiping the tears away. "Oh…Todoroki…Um…Everything okay?"

"Midoriya, Mineta is an idiot," Shoto pointed out calmly. "He's a perverted bully and lashes out when he doesn't get his way and he's completely wrong."

"Sure, he is," Izuku remarked bitterly. "I've never been a desirable Omega. My body just isn't built the same way as one. I'm not curvy, and my personality can be docile, but not enough. I've heard it plenty since I presented. No Alpha wants an Omega to like me."

"I want you."

Startled, Izuku looked up at Shoto. "I…what?!"

With a small smile, Shoto walked toward him, until Izuku had backed up against a wall and bent his head till their lips were a breath apart. "I want you, Izuku Midoriya…" And closing the distance, Shoto kissed him.

Heat pooled in Izuku's stomach. The feel of Shoto pressing against him warming him down to his toes and Shoto's scent positively screamed his interest. Breaking the kiss, Shoto nuzzled at his throat. "Shoto…" Izuku panted.

"I want to be your mate, Izuku," Shoto told him, kissing his temple. "If you'll have me."

Laughing through his tears, Izuku nodded and yelped in surprise, when Shoto scooped him up, the Alpha smiling widely. Throwing his arms about his throat, Izuku nuzzled in, his scent intertwining with Shoto's, their joy hard to miss.
