ALSO I LOVE COMMENTS THX BAIIII-

Heroes

People who stand out against the average joe to fight for what is right no matter what issues is in front of them. To be a hero is to be brave and courageous, it is not supposed to be a commodity, it is to foster hope within people. That is what it is to be a true hero. Someone who saves others because they looked like they needed saving. Not for the money, not for the greed, but to be helpful.

Izuku stared down at the philosophy he had written down. It was the classic verb of the past. True Hero… Those were far and in between. While people did try their best to help, some people with large and flashy quirks needed work that suited them, and the hero industry was that. Some people don't have the guts, some do not have the brains, some do it for honor. And this philosophy would be the downfall if it were to ever become popular.

Izuku had been graphing out his data that he had compiled on the situations of recent Hero encounters. For some reason there was an edge in the air for the average populace. He had just finished filling out another journal "Hero Incidents of Year XXXX #1" He placed it next to his corkboard which had various instances surrounded and connected by red yarn.

It was at this perfect moment that Enji Todoroki came barging into his room.

"Izu- What's this?" His father had demanded as Izuku had managed to hide his journals before the man had noticed his charts and data.

"Uhhhhhhhh- Nerd stuff?" He laughed awkwardly as he scratched the back of his head with with casted hand.

Enji rose a brow as he examined Izuku's room. He had made it a habit to visit his other son at least once every three hours. It was a new part of his schedule but he enjoyed catching the boy unprepared and seeing his nervous smile. It reminded him a lot of Inko.

"N-E-R-D stuff?" He phrased out the word.

"Y-Yup!" Izuku nodded while looking around nervously, "is there something you need… Uh.. Dad?" He quipped.

"D-Dad?" Enji could only feel the smile on his face broaden.

"Nothing." He replied before ruffling Izuku's hair up and then leaving.

Izuku stared after in awe at the strong man before trying to focus on his notes. That was until his room became terrifyingly cold. Ice began to ship at his belongings as Izuku turned his head to see his older brother glaring down at him hatefully.

"S-Sho-Shoto? Wh-What's wrong?" He managed to stutter out in the freezing cold. Something was wrong… and he began to feel pain.

He didn't know what had come over him. When he first met the boy he wanted to protect him. But the more he found out, the more he witnessed, Shoto's blood boiled. His anger was uncontained as puff of air were visible in the cold. And before he knew it, Shoto lost the small amount of control he had.

Maybe it was because Endeavor began hounding him even more recently, as if Izuku's existence fueled his need for a successful heir. His blood was about to explode out of his veins at the thought of the bastard sperm donor. And when he looked at Izuku, he couldn't help but see that same ambition. He wanted to snuff that flame out quick. It might even be the best for him in a cruel way.

"Don't even think for a second that because you have his affection that you'll be able to become a hero. You're just like him- An arrogant little bastard with no virtue."

At this point Izuku was confused by his elder brother's speech. For what he knew he hadn't done anything wrong this time. The cold was beginning to nip away at his skin. His breath turned into steam as his eyes began to lose focus.

"S-Shoto- P-P-Please… stop!" Izuku had to scream out as his body began to convulse.

He had gone too long without sugar because he had been focusing on his project for such a long time.

"Stop faking it!" Shoto growled out as he approached the trembling boy in pain. With swift and adept action he kicked Izuku in the side.
"Gah!" Izuku groaned out trying to protect himself by huddling into a ball, only to receive three more powerful kicks to his back.

"P-Please…"

Kick.

"AGh-"

Kick.

N-No-o…"

KICK.

One would think that the bastard Enji Todoroki would be busting down the door… But Shoto had closed the door behind him and blocked off the room in freezing cold ice. The green haired bastard in front of him could scream all he wanted, but he could care less.

Izuku watched with shaking body as his world began to darken. He was curled in pain and his brain was going into overdrive without the sugar to regulate it. Izuku felt like he was dying. In his quick attempt to save his life after narrowing down his options into the tens of hundred, Izuku grabbed his pencil and stabbed in Shoto's foot. Blood came pouring out of his mouth as he began coughing up a storm.

The seizure had finally stopped but the pain hadn't. When he laid there cold, Shoto had finally stopped. Looking over his half-dead brother he shoved a piece of mint into Izuku's mouth and then left.

Shivers colder than ice went down his spine as he looked back on the pained face of the younger boy. The way he looked at him and pleaded for him to stop…

It was just like he pleaded for his father to stop all those years ago… Shoto was acting just like Enji, and never before did he want to rip off his skin.

He was a monster...

"Shoto…" His thoughts snapped away as the young green boy looked at him with dull eyes. Those eyes were haunting him as the ice in the room continued to ravage at the boy's skin.

"Please…" Izuku's eyes dimmed.

"Help.."

||Break||

He had once prided himself on the fact that he had control, and unlike his father he was rational. Yet here he was caring for a younger brother that he had injured beyond his own thoughts.

Blood stained Izuku's shirt as one of the stitches that were on his waist ripped open. His lips were split from the rough way Shoto had shoved a sharp piece of sugar into his mouth. Izuku had twiddled his thumbs as Shoto couldn't bear looking at him eye-to-eye.

"I-I'm sorry." He muttered out sincerely.

Izuku looked up at his older brother as looked at his bandages.

"You patched me up, so no harm no fowl. I'm pretty sure I went through this type of go-to before in the past… But next time, you should find an actual punching bag.." Izuku trailed off as he traced some of the deep scars that resided on his wrists. They were previously hidden by his uniform, so no one had noticed the burn marks that spread across his skin.

"It's kinda funny though, I remember seeing you in the hospital… At least I th-think?" Izuku trailed off awkwardly. His sentence cut off as he tiredly closed his eyes, "I'm sorry to have caused you some stress, but I don't think lashing out at me until I'm deathly will help you…"

"I understand that you've gone through some stuff, I don't know what it is… But I know that you aren't like Dad… I haven't known you all for very long, but I can tell that you are your own person. And judging by your behavior… That applies to your quirk too. And this might be biased, but you should be happy that it's a combination of two powerful quirks that became one and only, which you control." Izuku sighed as he looked at his hands.

It took a while before the older of the two finally sat down next to Izuku.

"Life sucks, and I can't really explain much because I haven't lived it. But isn't it up to you on how you want to live?" Izuku consoled.

Shoto still remained quiet, which concerned Izuku greatly. Reaching down into his backpack near his bed, he pulled out a journal which he had been keeping about their household.

And in the most dramatic and Presenter-Mic esque tone he could, he presented his very little memories about his older brother Shoto.

"May I present to you my fair audience! The story of Shoto and Izuku, two brothers of different pasts but together a new future! Shoto is a hard worker with diligence and pride. He is a person striving to be a hero, just like the young Izuku. With his power and his mindset he can save millions! He's the hottest and coolest in town, he is… SHOTOOOO" Izku teased awkwardly as he poked at his older brother.

"C'mon, even my awkwardness makes people laugh!" He managed to smile weakly. His voice was hoarse from screaming and when Shoto finally looked up at him, he had tears in his eyes.

"Kff." he snorted. "I'm sorry for calling you a weak bastard…" he mumbled out softly with a smile, it was hard for him to contain his laughter.

How could anyone hate this kid? He was so stupid for venting everything out onto his brother...

"And I'm sorry for sneaking into your room at night to take notes on how you expose your vulnerabilities while unconscious."

"..."

For the next two weeks, Shoto slept with his door triple locked. It brought concern to everyone except Izuku.

"Sh-Shoto, why does your door have three locks?" Fuyumi asked.

"Green devils roam at night…" he said nonchalantly before going back to his room to retire.

"Izuku?" Fuyumi questioned with worry.

"All I did was take note of his psychological vulnerabilities while he was sleeping…" izuku mumbled unhappily as his number one time passer had disappeared. What was he supposed to do at night now? Sleep?

"..."

That night the entire Todoroki household locked their rooms while they slept, thoroughly annoying a young and sickly fourteen year old who finished all his homework.
