UA's Gremlins

Revenge is Really Best Served Hot....

Explosions rocked the bar, and it was all the teens could do to keep Katsuki from attacking the monitor. He was seething at the blurry screen. At the bar, Kurogiri tended to Izuku's injuries, which included several cuts, bruises, and a broken forearm. Izuku watched, eyes just as angry, but a coldness about him

"It's your fucking fault he got hurt like that, you fucking ugly ass potato!" Katsuki screeched. Dabi held him with just his arms hooked under the blond's, but he wasn't trying as hard as he could.

Not one of them was happy to see Katsuki carry the bleeding green gremlin into their base. Especially not when Kurogiri finished his call to the school. He had gotten the suspension removed, but not without cost. No punishment for anyone but Izuku- a week of cleaning the classroom by himself.

Toga wanted to go make the bullies bleed. Shigaraki offered to make them vanish. Dabi offered to help. When All For One had popped up to check on them, Katsuki went feral.

In the aftermath of his outburst, no one knew what to say or do. It was Izuku who spoke up.

"Master, may I plan their real punishment?" Izuku asked, voice calm and quiet.

All eyes went to where Kurogiri was finishing the cast of his arm. "How does that feel, my boy?"

Izuku beamed at him. "Perfect, Mamagiri. "

"Clarify what you mean, Izuku," their leader said.

Green eyes turned to the screen and his siblings. "Well one would be perfect for the nomu project. He has wings that could be used to make a flying one without an additional quick being needed. The other two...I just want to hurt. It would be fun to show them what I can really do. Plus...I need a break from being so good all the time."

All For One smirked. "Of course, my vindictive son. Do as you wish, but leave no trace."

Izuku just grinned, a wicked glint in his eyes. He looked to Toga. "Sister, can you help?"

The blond giggled and sprinted off to get her favorite knife. Izuku laughed then held out a hand to Katsuki as his best friend pouted. The other blond went to him, fingers tender as he touched the cast and each bruise.

"I know you want to go," Izuku said sweetly. "But if I let any of them live, no one is going to believe it was me...when I have the number one student in school as my alibi. That's why they can't see us together. Not in that way."

Katsuki made a disgruntled noise, but pressed his forehead gently to Izuku's. "Just wear a mask and let the blond psycho do the dirty work."

Izuku grinned. "I promise, Kacchan. Now help me change?"

Katsuki nodded, letting Izuku take him by the hand and lead him away.

"Just change! You don't have time for anything else," Shigaraki hollered, a look of disgust on his face. He didn't care they were together, but he couldn't stand the thought of the two of them engaging in anything like what he and Dabi did together in his room.

"Get fucked, crusty!" Izuku called back as they went up the stairs. Dabi cackled as he headed to get a drink. The screen grew dark behind them as the family went about their lives.

A bit later, Izuku strolled down with Katsuki at his side. The older boys smirked at the terror Izuku had become. The boy looked far older and more dangerous than before.

Sleek black dress pants elongated his legs and the peek of pristine white beyond the fitted black vest made him look regal. The snow white sleeves were rolled up to just beneath his elbows, and black leather embraced one hand. The cast was covered by a coat expertly slung over his shoulder. The deep red fabric of a mask covered the lower part of his face, leaving only his mop of green hair and his newly mismatched eyes.

Katsuki smirked in pride as Shigaraki stared. "Looks good, doesn't he?"

"Like someone completely different," their older brother agreed. "How'd you do the change in his eye?"

Izuku grinned and tapped his cheek beneath his blood red eye. "Contact lense. It was Kacchan's idea."

The blond smirked. "They'll believe the little rats less with it. I mean everyone knows our boy with Emerald eyes."

Izuku hugged him with his good arm as Toga skipped over.

"Ready to go, little brother?" She asked. "I can't wait to see that sweet, sweet blood."

"Take Dabi too," Shigaraki demanded. "Especially with your injuries."

The black haired man tipped his head, looking to Izuku for permission. The green haired boy sighed.

"Fine! But I'm in charge. Master said so," he pouted.

"Whatever you say, squirt," Dabi grunted as he downed his drink and joined them. "Lead the way, Tracker."

Izuku grinned, waved at his family and trotted off with his older siblings in tow.

Katsuki grumbled about being left behind and sulked at the bar, ignoring Kurogiri's attempts at conversation- red eyes locked onto the door.

****

The house was small, but not poor. Mismatched eyes stared at it as white teeth flashed in a wicked smirk.

They had taken care of the winged boy, already having gotten him off to Master. The second boy had been out with his family...but they would come home to ashes and rubble.

The third...he was the one who had tried to shove him out the window. He was the one who set Izuku up. He was going to suffer the most...maybe.

Steps started toward the dark house, grass softly crunching beneath his feet. Two other steps followed, one with a skip to it.

"Toga, take the front. Dabi, the rear. Whistle when it's time."

The two split off as Izuku came to a stop. He would be in full view of the boy's window. Now he waited.

A low whistle sounded, and Izuku smirked. He had long since developed a code of whistles to tell his siblings how to move when he couldn't give verbal cues.

And so it began...

Izuku returned the low whistle with one that grew in pitch and volume. In seconds, blue flames burst into existence, and a woman screamed from near the front of the house.

Izuku kept his eyes on the boy's window as he gave another whistle, sharp and high. The woman screamed again before Toga reappeared, blood smeared on her white sweater.

The flames spread as mismatched eyes watched the window jerk open. A body flung itself from the window, crying in terror. He landed with a thud, right at Izuku's feet. The boy groaned as he rolled over and stared up.

Light from the flames made the teen standing over him look eerie and terrifying as Toga giggled behind him. Izuku just smiled as Dabi joined them.

"What's wrong?" Izuku asked innocently.

"Y-You! I knew you were rotten!" The boy wheezed, a shaking finger shoved his way.

Izuku smirked, and his foot slammed down onto the raised arm, smacking it to the ground. He increased the weight as the boy wailed in pain. The wail turned into a scream as a satisfying snap was heard beneath his foot.

"It's not nice to point fingers," Izuku cooed sweetly. "Now that won't be a problem."

With a sharp twist of his foot, he pulled back. In the distance, you could hear sirens. A warp gate opened behind them as Izuku crouched down, the fire lighting up his face.

"I'll...I'll tell!" The boy sobbed.

Izuku laughed, dark and cold. He smirked as he leaned in close.

"Who would believe you?" He breathed. "I'm just a quirkless nobody, right?"

Toga and Dabi strolled through the portal and Izuku strutted after them, pausing to cast one last, sinister grin before putting his finger to his lips in a shushing motion and stepping into the darkness.
