Within the massive prison Tartarus the villain All For One sat behind thick glass in a special harness specifically made to prevent his quirk use. On the other side of the glass sat the emaciated form of All Might.
"How are my sons All Might?"
Blue sunken eyes glared at the villain.
"Izuku and Shinichi are not your children Akatani."
If the human fried potato's face could move his face would have show great surprise.
"I haven't been called that name since my beloved little brother passed."
"By your hand!" The hero angrily replied.
"My, my All Might adopting your replacement's anger?"
The hero gritted his teeth.
"Why?"
"I'm not a mind reader All Might and even if I had had a quirk like that my son stole all my quirks but my own so you'll have to tell me what exactly you are asking."
Blues eyes with deep black sclera glared at where the eye's of the villain had once been.
"Why did you create Izuku and Shinichi?"
A smirk showed on the face of the villain.
"I decided to take a page out of my beloved little brother's book and find a successor and who better than a clone of myself?"
"Izuku is your clone?"
The smirk fell a bit as the villain continued.
"Well not entirely I could only remove so much of that woman's dna to create him."
Blue ringed in black glared into the villain's scar tissue covered eyes but they presumably were emerald green just as in Izuku.
"And Shinichi?"
"A means to an end. I had the idea that a little brother would make my son come back apparently I was wrong."
The hero looked as though he was about to speak but was interrupted by one of the guards.
"All Might you have three minutes left."
"May I bring in my guest?"
The door opened behind him in response.
Allowing in a raven haired boy his emerald eyes trained on All For One.
The hero stood in the back of the room allowing the boy to sit.
"Mikumo how have you been son?"
"I have my provisional license now."
Emerald green eyes full of determination stared in the scarred face of his father.
"I'm one step closer to my goal."
A smile appeared on the villain's face but unlike the smirks he had shown the hero this one was almost like a father proud of his child.
"And what is your goal Mikumo?"
"I wish to make this terrible world a better place for my little brother whatever means necessary."
The villain looked as though he was about to speak but was interrupted by the guards.
"Your time is up All Might."
The door opened behind them Mikumo quickly leaving but before he could get out the door All For One yelled at him.
"I love you... son."
Mikumo stepped out of the room.
"I know."
He said subconsciously rubbing the puncture wounds on his arms.
A raven haired boy walked into a rock and roll themed room collapsing on the bed.
When he had nearly fallen asleep his eyes snapped open.
"Shit I promised to help Mei tomorrow."
The pink haired machine loving girl had put the finishing touches on the gun's blueprints.
Izuku reached for it only for it to be held behind her.
"Ah Ah Ah."
She said shaking her head.
"What?"
A smile appeared on the pinkette's face.
"In exchange you get to test one of my babies!"
"What why?"
"It's the Mei Hatsume policy to test a new baby on a victi- err subject who is already using one of my products."
Rubbing his eyes the boy glared at her.
"Fine when are we doing this?"
"We can start two days after your license exam!"
"Joy."
Izuku stepped into the support department.
Looking around he spotted a pink haired machine crazed girl.
"Hatsume."
She looked up from her current experiment (was it some kind of toaster?) and straight at him.
"Hey what're you doing here?"
"You told me to come help you with an experiment in exchange for the weapon you made for me."
"Oh right!"
She turned away from the mega toaster and went to a large backpack.
Picking it up she nearly fell over due to its weight.
"This baby is a Jetpack."
"And I'm going to test it?"
She nodded vigorously.
They stood in the field outside the school.
"Are you sure this is safe?"
"Not in the slightest."
Hatsume held a remote pointing it at the large backpack.
"Wait wha-!?"
She pressed down on the button that said up sending Izuku flying into the air eventually stopping 50 feet from the ground.
"That's to high."
She pressed the down button but it didn't work.
Black smoke began flowing from the back of the jetpack.
"Uh oh."
More black smoke flowed out sending Izuku tumbling to the ground.
"Aaaaaaaaahhhhhhhhhh!"
Green and purple lightning flowed around him as he hit the ground making it crack with the sheer force of his landing.
"Is my baby okay?"
Emerald green looked up at her.
"It made me go insanely far up and then dropped me straight to the ground but other than that it's fine."
"Good!"
If Izuku could smack his forehead he would have.
"C'mon there's way more tests to do!"
His only response was a groan.
