Inko did the one thing any concerned mother would do, and called the authorities. She described the kid to the officer after she gave him a bath, and the police almost thought it was a prank call. She watched him playing with her son in the living room. Inko had given the child Izuku's clothes, which almost didn't fit him given his right hand, which she discovered was his actual hand! Other than that, the clothes were too big for him and were a little baggy. Izuku had forgotten about the situation with the hospital it seemed, he was only infatuated with the devil-boy for now, which Inko was really glad about. She knew it would be temporary, however, as this child would be sent back to his mother or father or whichever foster home he would go to.

When the authorities arrived, Inko was met with the lieutenant, Kenji Tsuramagae. His quirk being that of a dog head, but nothing much more. He caught a glimpse of the kid and immediately jerked himself back. He looked towards Inko, making an attempt to appear calm. He asked to speak with her outside, which she nodded before Izuku ran towards his mom, showing her what looked like a crushed toy car.

"MOM! Look at how strong he is!" Inko looked wide-eyed at what such a small child was able to do to a plastic car.

She smiled at Izuku, "Wow, would you look at that! He's a strong boy isn't he?" She looked back at the officer before kneeling down to her son, "Honey, mommy has to speak with the police officer outside for a minute, can you be good for the other officer?" her son nodded. "Okay, I'll be back inside in just a little bit."

Izuku ran back towards the red boy, Inko smiled and walked out with the officer. He was leaning on the side of the apartment building holding a cigarette so Inko could see it.

"You smoke?"

She shook her head, "No."

"Mind if I do?"

"I don't mind."

He took a second to light the cigarette, took a long drag of it, then let out a dramatically long sigh. You've found yourself in quite the predicament, Mrs. Midoriya."

Inko began to sweat. "P-predicament? Well, I suppose it's not every day you find another child in your home."

He turned to the mother, "Not just any child. Do you remember that incident three months ago?"

"You mean the one with the video, with All Might saving all those people? Yes, my son is very passionate about All Might being his favorite hero. He watches that video every day!" She smiled over the city, which was dimmly lit by night owls and street lights alike. "W-why is that important? If you don't mind me asking."

The lieutenant sighed, obviously hesitant to share the next bit of information with her. He tapped on the railing for a solid twenty seconds before returning to her.

"A lot happened that day, a lot of calassified information no one but a handful of individuals know about."

Classified information? Inko began to panic a bit, What does this have to do with that boy?

The dog-man turned his whole body to look Inko right in the eyes, "During the fight, there was a device the villains were using, a portal of sorts. Though the device itself was destroyed, it was used. I cannot tell you what it was that was in it, but what I can tell you," he raised his head, turning his whole body to the concerned mother and his left hand towards her apartment, "is that the child in there, he was a product of the portal."

Inko was in shock at this point, I'm housing the child of some freak experiment villains were cooking up? She thought back to the child, how he clung to Inko and how easily he trusted her. How obedient he was during the bath, if not a bit messy. How dirty he was when she found him stealing her leftovers. She began to deny it, but then thought about how he looked, the horns, the red skin, the tail, the eyes that looked like they were ablaze. Practically the Devil

"However," the officer continued, "I don't think he's inherently bad. I mean, he seemed to be perfectly fine with you and your son for the short time you've had him. Even Eraserhead, a newbie hero that's soared through the ranks of popularity, seemed to refer to him as a cautious animal, not even trying to attack him but instead fleeing. We have gotten a call of one attack, but no one was hurt. Otherwise it's just been stealing food and trespassing."

Inko was crying at this point, worried about her son, concerned with the boy she found just hours ago and panicking with the knowledge that she is being trusted with confidential information that she believed could get her - No - Izuku, hurt or worse. So many thoughts were going through her mind and so much stress was accumulating that she felt like vomiting.

The officer tried to explain a bit better, in the hopes of consoling the woman that was murmering to herself. "Like I said, he doesn't seem bad in the slightest, and does seem to trust you and your son. We want that kind of trust to continue." He put out the cigarette, then put his hand on her shoulder, "This is an odd request, and you are free to decline if you wish. However, the entire situation is strange in of itself. I want him to grow up right, like a normal kid if possible. So, I offer you the option of adopting the boy, letting him grow up alongside you and your son."

Inko didn't want to at first, it seemed like a much too risky thing for her and her son to be exposed to. But then she thought of Izuku, how devastated he was earlier today after being told he was quirkless. About the heroes he looked up to, and what they would do in this kind of situation. She ultimately made her decision, definitely not for herself, and not even on her own blood son, but on the dilemma of the child. She recognized his appearance and potential threat, but also saw his ability to trust her and Izuku and how difficult it would be for anyone to grow up without a mother or a father to turn to.

She wiped her tears on her sleeve, looked up at the officer with determination in her eyes. "Okay, I... I will take full responsibility for him."

The officer smiled, throwing the cigarette on the ground and crushing the fire with his foot. He looked back to the door to her apartment, "Then, we will send the documents and papers your way for the process."

She smiled back, turning to the door as well, then back to the officer. "Um, so, does he have a name or is that going to be my decision as well?"

"Well," The officer turned to her, scratching his head, "The hero branch that was involved with the search of him already had a file made for him. On the files, which will be copied and transferred to you, we did have a name for him already. One they thought suited him well."

"A-and, that would be?"

He looked to her, lifting himself off the railing and beginning his walk towards the door of the apartment, "They named him: Hellboy."

Two Weeks Later

Izuku was excited to introduce his friends to his new brother! Despite his age, Hellboy was allowed into the same grade as Midoriya due to how much him and his mom had been teaching him Japanese and math. As the young green-haired boy ran through the forest to the usual spot, Hellboy was leaping through the trees only keeping a bit ahead of his brother.

"HEY, HOW ARE YOU SO FAST?" Izuku asked the leaping devil.

He stopped in one of the trees, "I dunno, I just like to hop around!" He giggled as he waited for his older brother to catch up. For the rest of the way, he kept pace with his slower compadre. When the boys finally caught up with the gang, Katsuki immediately pointed to Hellboy.

"What is that?" the blond shouted. Hellboy hopped to the ground, waving his left arm in the air.

"That's my new brother! Isn't he cool?" Izuku's smile was wide and eyes sparkling, he was very proud of his brother. He was able to help him learn a hefty amount of Japanese within two weeks, he was almost as fluent as one of the others at this point. The fact Izuku was able to help his new family member so much in learning a language really stuck out to him and made a really strong bond form between them in such a short period.

"Whatever Deku, just don't let him get in my way!" Bakugou boasted.

Hellboy's head tilted at the name, "Deku? Hey Izuku, what does that mean?"

Izuku's head lowered, his thoughts brought back to reality about his own situation. Hellboy scowled, I don't think I like that name. Whatever it is.

The blond boy turned his back to his friends and began to lead the way. "C'mon! It's time to find something to fight."

After a while of marching, the boys stopped at the usual river with the bridge. Izuku was still trapped in his thoughts as he followed Kacchan over the bridge. I really can't do anything, can I? At least I don't have to anymore, at least now Hellboy can be the hero now, right? Does he even want to be a hero? I bet he would make a great hero.

They were all over the bridge now, and Katsuki was looking over the edge of the bridge, as the other two boys watched with him. The river was the only sound that could be heard, the water trickling through the forest and hitting the rocks, driftwood and wooden pillars holding the bridge up. Birds sang their songs freely in the sky and bugs buzzed in the brush of the forest.

Hellboy tapped Izuku's leg lightly with his tail. As he looked over to his younger brother, he could see the worry on Hellboy's face. He was peering over the water, looking at something in the distance, "What is it?"

Hellboy responded with his face glued in the same direction, "I thought I saw something. Something big."

The boy almost responded but was distracted by a loud snap in front of the two. They both jerked their heads towards the other boys, with only two out of the three others being present and a log out of the bridge gone with the other. Bakugou had fallen in!

The quirkless child ran down to the water to help his friend, Oh no! I hope he's not hurt at all. As he got to old friend, he stretched out his hand. Bakugou took a second to stare at the hand, at first surprised, then disgusted. He was about to lash out at the green-haired boy but was stopped by the new member of the group shouting.

"GET OUT OF THE WATER, NOW!" The red boy leapt through the air, at what the boys saw was four giant turtle people the size of a grown person hurtling towards them. Hellboy smashed his right fist into the closest of the turtles, with a grotesque sound of the shell cracking. It recoiled, Hellboy jumping back to his brother and his friend. Bakugou had gotten to his feet at this point and Izuku was scared frozen.

The turtles stared at the three boys, the one Hellboy smashed with his hand growled at them. The other three howled into the air, showing their sharpened claws at the edge of their hands..

"What kind of quirk is that?" Bakugou shouted, with a bit of unease in his voice.

Hellboy responded, "I don't know, and I don't care. They're going down either way!"

One of the turtles rushed through, Hellboy instead met it with an uppercut with his right fist. The turtle recoiled into its brother, sending them both crashing onto their sides. Another was already trying to slash at Katsuki, but he used his explosive quirk to confuse him, then used both hands and a lot of energy to send the turtle flying backwards. The first turtle already had his eyes set on Hellboy, trying to bite his tail. Hellboy met this with a backhand with his right fist and another downwards punch with the other fist, sending the turtle into the river water with a respectable splash.

The blond came into the frenzy with a powerful blast to one of the turtle's faces. This gave the devil boy enough time to break the same turtle's bottom shell and land a punch into its gut. That turtle was out for the count, blood flowing into the river.

A squeel came from behind them, the first turtle was trying to attack Izuku! Hellboy rushed the turtle, grabbing him from underneath and pulling him through the air, into the other two turtles past Katsuki. The first turtle's shell broke, and the other two turtles were knocked onto their backs. They tried to get up but only failed in that attempt.

Bakugo turned to Hellboy, "I DIDN'T NEED YOUR HELP KID!"

Hellboy simply strolled past Bakugou, "I'm sure you didn't, but I still dealt with it." He stared at the two remaining turtles. "So, what should we do with these guys?"

Deku shouted, "Hellboy!"

Both boys turned their attention to the quirkless boy, who was pointing in the direction of the two turtles already defeated. Their bodies, as well as their blood, began to glow. The children took a few steps back, Hellboy raising his fist in preparation for an attack. However, the glow quickly changed to ashes as the bodies began dissipating and floating away as embers. The bodies of the turtles were gone in seconds, as if no turtles ever attacked at all. The boys turned towards the last two, in amazement at what just happened.

Hellboy was the first to shake off the light show. He walked towards the other two turtles, hopping on one's stomach and raising his right fist. He put all his force into the punch, smashing the third turtle's head into itself. He repeated the same with the last turtle. Just like the first two turtles, they glowed into embers and fluttered away into nothingness.

Hellboy turned towards the boys. All three of them astonished at the now gone turtles. The three eventually made their way back up to the trail and met up with the other two boys. They made their way home.
