In MHA with JJK powers.

"Would you like to become my new successor?"

Mechamaru's unblinking green eyes stared in silence, looking straight at AFO inside his life support machine.

Through his control of cursed energy, he has already found out about Shigaraki who was silently hiding behind the wall to his left.

Quitely listening to their words.

"You will become the most powerful villain to ever exist."

It was impossible for AFO not to know, he had Ragdoll's quirk with him.

"How about it? It seems like a pretty good deal no?"

What was his motive? Was he trying to sow discord? But why? It didn't make sense.

A light passed through Mechamaru's eyes.

.....Or perhaps it was a test?

 "What use do I have? Of the powers from a defeated villain?"

AFO fell silent.

Shigaraki hiding behind the wall narrowed his eyes.

"Hahaha it seems I am underestimated..."

Bubbles appeared inside the life support machine, blocking AFO's face.

"But indeed, what use would the winner have of the loser's power?"

His self-deprecating voice rang out throughout the place.

"Forget that I said anything...."

Mechamaru turned around and started walking away.

But just then.

"Kurokai Sento."

His steps came to a halt.

"After analyzing everything and confirming with my spy at Ua, I am 90% sure he is the one who helped All Might recover."

Turning back Mechamaru looked at AFO.

"There is something I need you to do."

His voice filled with clear longing.

"Go to Ua, bring him to me, Kurokai Sento. With his quirk, I will recover and get back to my peak! Out of this piece of iron!"

The life support machine holding AFO shook under his terrible aura.

"Mechamaru for you It will be an easy feat---"

"All For One."

A mechanical voice interrupted his ambition.

"I am not one of your mindless servants."

A pair of green eyes stared unblinkingly at him.

"You do not have the right to command me."

The water inside AFO's life support machine moved in confusion.

"Servant? Of course not Mechamaru what we have is a partnership. I am not commanding you it is simply that benefits both of us---"

"Use your word game on someone else."

Interrupting him again, Mechamaru turned around and started walking away.

As he was making his way towards the exit.

Several red branches silently extended from AFO, rushing towards Mechamaru's unprotected back.

But before they could even reach him, the world changed colors.

Coffin Of The Iron Mountain.

The branches burned away in an instant, turning to ash.

AFO's body shook, and although he couldn't see, the sheer terror and power emitted by the space made him fall silent.

"The heroes bonded by the law only left you with a broken face."

Mechamaru said in an unhurried voice.

"But there's only ash in my path."

Throughout the entire process, he didn't look back, showing his back, the so-called blindspot, presenting it in front of the ex-strongest villain, challenging him to attack, unbothered by his methods.

Because AFO knew.

The moment he tried.

Ashes will be all that remained.

"Remember it well, a mercy from me, the only second chance I give you."

Mechamaru started walking again.

"After all Shigaraki would be sad if you were gone."

With that, the world world changed again returning to the original.

Silence enveloped the place.

But then.

AFO inside the machine started trembling.

His mouth cracked open, forming a creepy grin.

And for the first time in many decades.

"H-ha-hahahahaha"

He was laughing in pure unconcealed joy.

"Hahahahahahahahahahahhahahahahahaha!"

Shigaraki walked out from behind the wall, looking at AFO with dull eyes.

"I see it!"

He shouted in an excited voice.

"I feel it!"

He touched the cold metal with his hand.

"All Might---No the world order will change!"

"The birth of a true monster!"

"How wonderful! How exciting!"

Suddenly he calmed down and continued.

"But.....this might be a problem for you Shigaraki."

"If dealt correctly, he is your strongest support, if dealt incorrectly...heh..."

Shigaraki stared at AFO in silence.

"I have changed my mind."

The life support machine trembled breaking apart, revealing AFO's figure.

"Originally I wanted to wait for you to grow a little, gain more experience, gather more allies but now...."

AFO floated in the air with his arms spread out as if to envelop everything.

"I see no need for such unnecessary actions."

"I will call the doctor."

Shigaraki's eyes shone.

"We will begin transplanting All For One."

He stepped on the ground, standing right in front of Shigaraki.

 "The world is changing fast, if we do not want to be left behind, then we must hurry as well."

AFO raised his hand and patted his shoulder.

"Since Mechamaru considers you as a friend, he wouldn't mind kidnapping Kurokai for you yes?"

"How about you try asking him Shigaraki? For your teacher's sake?"

Listening to AFO's words, Shigaraki narrowed his eyes and then nodded his head.

---- 

After leaving the room, Shigaraki made his way towards Mechamaru.

In no time he saw his familiar figure, working on his usual workbench.

"Yo mechamaru."

With a smile on his face, he appeared beside him, curiously looking down at the grey armor he was making.

"There's something I want to ask you---"

"You want me to capture Kurokai?"

Shigaraki's smile froze.

Mechamru also put down his equipment and looked straight at him.

"AFO must have asked you."

Shigaraki started ruffling his hair and said.

"The teacher he said....."

"But is it truly the best for you?"

Mechamaru continued in a calm voice.

"Tell me, what do you think will happen if AFO was to recover."

Shigaraki stopped and stared at him with narrowed eyes.

"If he was back at full health, why would he bother to give you his power?"

"You knew?....."

His eyes shook.

"It's not hard to guess."

Mechamaru offered him a seat, telling him to sit down.

Shigaraki complied without any resistance.

"You know AFO better than anyone, he is not a selfless person."

Shigaraki crossed his fingers.

"If he were to recover, I believe I need not say what will happen yes?"

"So why bother helping the old fossil?"

Mechamaru clenched his palm.

"When we can become the new legend."

"You want me to betray teacher?"

They both stared at each other in silence.

Instead of replying, Mechamaru offered his hand to Shigaraki.

"I simply want the best for you."

"If you think I am wrong, then I give you the chance to turn me to dust right now."

Shigaraki stared unblinkingly at his outstretched hand.

In his reverie he failed to notice, Mechamaru's eyes turn blue.

"I believe even after transferring his power to you, AFO will use his conscious to control you."

"But worry not, as I have a way to deal with it."

He listened silently.

"So take my hand, Shigaraki."

Raising his hand he stared at his own pale palm.

"Together let us change the very foundation of society."

Shigaraki looked back at Mechamaru's outstretched hand.

Finally, he spoke.

"Mechamaru."

In a serious tone.

"What is your goal?"

Their eyes collided.

"To be feared by everyone."

The instant reply made a wide smile form on Shigaraki's face.

"You are as crazy as I am."

With little movement, he grabbed Mechamaru's hand.

"Then together we will turn everything upside down!"

Shigaraki tightly clenched his hand.

"My only friend, Mechamaru!"

[1000 Faith points collected, congratulations on receiving Megumi's ability "Ten Shadow Technique."]

The space around them shook in excitement.

----

Ua's dorm.

Aoyama inside his room, silently kept pressing on a machine, sending secret encrypted messages to the League of Villains.

But what he failed to notice.

Was an invisible figure silently looking at him with calm eyes.
