Izuku is a Therapist for the Meta Liberation Army

Finding out the Dad

"Let me ask again: what did you just say?"

"Oh, is the dad joke too outdated? I guess being in jail hasn't allowed me to broaden my comedy any further," All for One answered smoothly with a grin. "Just go on about your day now. I'll tell you more about my dragon-like treasure hoard again next time."

Midoriya narrowed his gaze on him, tilting his head at the man behind the glass. "Alright then. I'll take your word on it. Goodbye again."

As soon as Midoriya closed the door, he turned to one of the guards nearby. "See if you can get a blood sample from him. I need a personal test done to ensure his words on something."

"A blood test?" The guard asked. "For what reason?"

"I need a comparison to my own blood to test DNA similarities," Midoriya answered back, noting how the guard looked taken aback by his order.

"Alright, sir. I'll talk with my higher ups about your request. Stay here."

"Aye aye," Izuku saluted sarcastically back at him while the guard traveled down the hall. He walked away from the door and leaned back against the blinding white walls of the hall of Tartarus.

It wasn't long of a wait until the guard came back with a woman in a lab coat to  get a fresh blood sample from him to test. He relaxed again as the two walked back down the halls, leaving him in silence.

Maybe he was just overreacting. How could the most evil supervillain just casually admit that he was a father through a dad joke? All for One had to be joking with him.

Three days later, Midoriya received the results of the test through an email. An e-mail that basically read 'congratulations, your father is a super villain!' was plastered across his laptop screen with a little confetti.jpg in the corner.

It wasn't long before he was driving to Tartarus with a coffee-muddled mind. He headed straight inside with the excuse of a follow up therapy session. He pushed past the guards who were questioning why he came back so early.

Izuku bust open the door to find All for One still frozen in place from the amount of restraints tying him to his chair, "Are you kidding me?!"

All for One hummed at his loud response, smiling when his footsteps matched right up to the glass, "Ah, you came back."

"You! You?" Midoriya stopped in front of the glass and pointed at the restrained villain.

"Yes?"

"You weren't kidding?

"About my dragon treasure hoard? Not at all. Have you already found it?" All for One grinned like he was proud of something. "I have barely given you any hints about its location."

"No?" Midoriya answered confused for a moment. All for One turned his head slightly with his grin slowly slipping. "I'm talking about the fact that you are supposed to be my father."

"Oh, right," All for One coughed. His couch didn't break the uneasy tension in the room. "I was hoping you wouldn't actually hear the joke when you walked out. I was planning for something more dramatic for the actual reveal. But since you know now, it doesn't matter anymore."

"You... You are my dad? How?" Midoriya remarked, throwing out his hands to gesture at the tied up villain. "My dad is supposed to be in America. He is supposed to be sending letters and not tied up in the highest security prison."

"But I am afraid the letters stopped years ago, correct?"

Midoriya felt something drop inside his throat at the villain's words. "Why do...?"
