Story Summary | After long months, Garou reunites with Metal Bat in an abandoned building, and in every way, it's not as he expected.At least, he's glad that he arrived in time

✏️ Published on AO3 too.

SINGLE CHAPTER

Garou would never have thought that he would take refuge in an abandoned building. It wasn't his style to flee, no matter how strong his enemy was: he relished every moment of the battle.

But the monster outside... It wasn't a worthy opponent. If he could, the hero hunter would classify it as "a messed-up experiment gone wrong, escaping from the lab and ending up in the cities."

It didn't speak: it just repeated incoherent things, giving him a headache. How could an amoeba be so powerful? No... it was strong, but only because of its ability to corrode things as if it were made of acid. Garou didn't even try to strike it because when he was about to hit its head, he felt his entire body tingle, instincts telling him to run. That's when he decided to escape, but it was too late because the creature had already decided he would be its adversary.

And that sounded strangely familiar...

He needed a new approach to deal with the monstrosity that claimed to be a monster. That's why he leaped into the nearest building. Its structure was sturdy, but it wouldn't take long for it to be destroyed. Garou staggered, feeling chunks of cement falling from the ceiling, warning him that time was running out.

Climbing to the top seemed like a good escape plan: that thing didn't care about his presence until it sniffed him, which would completely change its focus to the hero hunter. Garou ascended the stairs, hoping the monster's attention had been diverted again, but the building shook once more, suggesting otherwise.

Reaching the third floor, the deafening silence ceased. Garou was on the last steps when he heard something like a painful whimper coming from one of the closed rooms labeled as an office.

He tried to ignore it, after all, it could be anything. A monster with a stomachache, just like a civilian injured by the amoeba from earlier... The thought strangely struck Garou. If it really was a civilian, he should lead them to the nearest ambulance or person.

"Damn, this hurts..." the muffled voice said.

Garou approached the door, slowly turning the doorknob, but it wouldn't open. In the background, he could hear painful moans. He sniffed but couldn't determine the person's gender behind the door.

He took a deep breath, fearing that opening it would reveal an omega in heat.

"Is anyone in there?" Garou stayed silent. "G-get out, it's dangerous to s-stay..."

"Hey, are you hurt? Can you get up?" The person behind the door fell silent, and the monster decided to charge as the building started to shake again.

"Yes, I am. But I d-don't need your help. I called for reinforcements, and—" they screamed, their breathing becoming irregular once more. "Aghhh, damn it!"

Garou turned the doorknob again, but something was blocking it. Why did he still insist?

"Let me help you, damn it. Are you a hero?"

"Yes!"

The hero hunter grips the doorknob. If he were a hero, he could handle this on his own. Heroes were tough, as resilient and annoying as cockroaches. However, there was something strange.

"Open the door," he ordered. "The building will collapse soon. Let me take you to a safe place so your idiot friends can pick you up."

Without questioning, Garou feels the weight on the doorknob lighten, and he discovers that what was blocking the way was a metal bat.

And then things start to make sense.

The sweet, slightly woody scent is so strong it feels like a punch to Garou. He bristles, memories of the last time he smelled this majestic scent, which drove him insane.

Could an omega have a scent as light as strawberries and a strong woody undertone like an alpha? Garou had never encountered such a being until he met Metal Bat.

"G-Garou?" The dark-haired man startles, his bright black eyes that he hadn't seen in months fixed on him, closing when Badd feels a twinge of pain. He lets go of the doorknob and holds his large belly.

There's an unmistakable bulge that leaves Garou in no doubt about Metal Bat's situation. He's not in his hero attire: he's wearing a loose gray sleep shirt, a leather jacket, and wet sweatpants.

He has a very pregnant Metal Bat carrying his offspring and a furious monster outside. This is not a good sign.

Garou touches his arm: Badd is warm, and his intense omega scent is driving him wild, making it hard to focus.

"What are you doing here?" he asks, finding the answer in the same instant as Badd tries to get up, but all he manages to do is push his bat further away.

He sucks in air through his teeth: his breathing is irregular. Garou pushes the black hair away from his eyes, tucking it carefully behind his ear. At this point, he knows it won't be long before his inner alpha screams to protect Metal Bat, to take him and care for this pup.

Garou wraps his arms around Badd, looking for a better way to lift him, but the omega groans in pain, his face covered in sweat, spreading his wonderful scent over Garou's clothes.

"What are you doing?" Badd asks, his voice low.

"Looking for a place where you can have this baby more comfortably," Garou grumbles. "Does your sister know you're here?"

Badd thinks for a moment, unsure whether to trust the father of his future pup or not.

"No, no one knows," he says. Garou puts his arm around the hero's waist. "That's why you should go... Ah, damn it. It's so low now." Badd's steps are getting slower.

"Go where?" the hero hunter asks, as if it were an offense.

Garou knows there are heroes coming, and a monster could destroy this building at any moment. But as soon as he encountered the omega, leaving this place was out of the question.

Tears start to stream down Metal Bat's face, accompanied by whimpering.

"Yes, but... I don't want you to go," Badd breathes deeply. "I need you."

This would be a good moment for Garou to taunt him, and he even starts to smile, but internally, he decides he'll save this moment to mock the omega later.

Removing his arm from Metal Bat's shoulder, Garou helps Badd to sit down and takes off his jacket, using it as a makeshift pillow for the hero to lie on.

"I'm not going anywhere," he reassures, watching the rise and fall of Metal Bat's belly, now covered by a simple shirt.

He extends his hands towards the bulge, believing that while he was away, his offspring was growing vigorously inside Metal Bat. One of the omegas he has the most respect for in his hero hunter journey.

There couldn't be a better partner for this.

Garou lifts the shirt, his hand touching the stretched skin of the hero. Their eyes meet, and the monster inwardly laments: he wishes he could have savored every moment of this.

Still, it's a miracle that they've found each other now.

Badd whimpers in pain again, and it's the alarm that makes Garou get up and search for anything that could help bring this child into the world.

Besides blankets and water, what else would be needed? The monster descends the stairs and finds some sheets: the time he spent outside has made him nervous, and returning to Metal Bat as soon as possible is a plan that sounds great in his mind.

Garou is more than bound to Metal Bat: he needs to be close to Badd. He needs to ensure that his pup arrives safely.

"What are you doing here?" It's Badd's question when he returns with more sheets and a glass of water.

"I could ask you the same thing."

Badd takes a deep breath, pushing his hair away from his face as he takes a sip of water.

"I heard a strange noise, so I came to see what it was."

He wants to scold Metal Bat for being so foolishly altruistic.

"Do you know how dangerous that is, you blockhead?" The exhausted look in the omega's eyes reaches the monster. "You're in labor! Are you telling me you didn't notice?"

"Yes, I noticed," he grumbled. "It's impossible to ignore this shit with a baby getting lower as you walk and the... back pains," he sighed.

"And like an idiot, you decided to face a monster anyway!"

"People needed help, okay?" Badd closes his eyes, his hand rubbing his stomach when a contraction comes. He takes a deep breath, grumbling and cursing softly.

Garou puts his hand over Badd's, his gaze fixed on the hero. The conversation didn't improve matters. Badd went after that monster out there? He wants to scold this disobedient omega.

"Wait, you fought that thing? You could have died! Both of you!"

The hero gives him a disapproving look, but Garou can't help but contain his anger.

"I didn't fight him. I just managed to buy time for the civilians to escape. After that, I made it to this building, but when I looked for a place to stay, my water had broken."

He grumbled. Garou isn't going to continue this argument, even though he's worried, and his inclination is to scold him until he understands the foolishness he's committed. However, he has other questions in mind that don't seem to have time to be resolved.

After the conversation, Badd starts progressing incredibly fast. The alpha offers his hand so that he can provide support, and the man gladly accepts.

He grabs his phone when asked to time the contractions, which are so close together they barely make it to two minutes.

With Badd in his arms, gripping his shirt tightly, Garou tries to get the hero to lie down again so he can remove his pants, but Badd's hold is strong. The omega sweats and cries softly.

Garou can sense his nervousness through his scent. He kisses the top of his head.

"Come on, blockhead. Let me check how you're doing. You know you need this." Badd nods, letting go of the fabric of the shirt.

He doesn't know how the hell to do this: Garou removes Badd's pants, and if he weren't so out of it, he would have protested. Placing the pants to the side, the hero hunter realizes how advanced his omega is.

Extending his hand for support, Garou provides it.

"Good, very good, hero."

"What do you... see?" Badd asks.

The image isn't that pretty. But knowing that he's close to having his pup, Garou feels anxiety eating at him.

"That you're almost there. Come on, a few more pushes."

"Alright."

As the omega makes progress, it seems harder to monitor and provide support. By this point, Garou is also sweating, practically sharing the same pain as Badd, who does nothing but grumble.

The walls shake, and Garou realizes that the monster is back. Damn it, he doesn't have time for this abomination. With Badd in his arms, he feels like this pup could come at any moment.

Badd ceases his cries of pain, containing them in his throat.

"Garou... I can't. Damn it, I can't..."

Badd's words are amidst painful mutterings, almost indecipherable. Garou sees this as a sign that they're almost there. He firmly holds the hero's hand, which is resting on his stomach.

"Where's your fighting spirit? You can do it. I'm here," Garou encourages. Badd grits his teeth, using all his strength to push.

Garou's breathing techniques help during the short breaks. It's a great help that inhaling and exhaling actually works for Metal Bat because the hero hunter feels lost amidst the screams and fabric tugs.

"It's all your fault, Garou! Damn... hunter of heroes!" Garou touches the omega's hair as he groans in pain, and through a strong and powerful push, their little one comes into the world.

The blankets he found serve to wrap the baby with whitish hair. With bloodied hands, Garou quickly covers the baby. A genuine laugh escapes the hero hunter: he's never felt so exhilarated.

The baby is adorable, with skin as fair as his, cheeks slightly flushed. Garou takes her over to Metal Bat, serving as support for the tired hero.

Tears welled up in Badd's eyes as he held her in his arms, he looked at her with the same fascination he used to look at Zenko. He repeats over and over again how beautiful the little one is, and the monster has to agree: their daughter is a cutie.

The monster's roar ceased, and then the door on the first floor was opened. It seemed like there were more than three people, and upon peeking, Garou realized they were all heroes.

The look Badd gives him is one of concern. Even though he's the one who needs the most help, the hero still worries about him.

Walking up to the omega, Garou kisses the top of his head and his sleeping little one.

"You need to go, idiot. They'll catch you."

"No. I'm staying with you." Garou grips his hand tightly.

"I know. But not now. I know you'll be back." Pushing him away, Badd signals for the alpha to leave. "Now go. You're not going to leave my side now that I have this little thing here."

The hero hunter nods, escaping moments before the others reach the floor where Metal Bat is. Garou needs to control his wolf when he sees them touching his omega and bombarding him with questions, but the look Badd gives him reassures him that everything is okay.

They say the slime monster was distracted and taken to another location. Garou climbs to the top of the building, watching an ambulance take the omega away.

He leaps to the next building, staying at a safe distance where the fools can't see him. Certainly, he is more than involved with these two. No matter what the Association thinks of him, Garou will not distance himself from the greatest treasures of his life, found by him on his long journey.
