"LUFFY BEST BOI" - All Might Muscle Form, Anger

The moment I was declared as a Quirkless was the moment I knew that I'd face nothing but pain and suffering...

I was young and hopeful, as I first saw him save people with his huge smile, I instantly thought that he was cool and awesome.

I wanted to be like him, to save people with a reassuring smile on my face.

I Admired him, Idolized him, he was my Inspiration till this day.

All Might had been an Irreplaceable person in my life.

He was like the Sun, burning strongly, a symbol of Light for the people burdened by their Darkness...

And that person made me his Successor...

I was beyond happy that he made me his Successor, that I can become a Hero because of his Quirk and I thought I had to try my best more than everyone else to be worthy of his Power... Because he chose me.

And he also promised me... That he'll live long enough to see me become the Greatest Hero ever... That's why...

"All Might please... please be okay...!" Izuku worriedly thought, he was panting as he ran and ran, desperately trying to find All Might who had gone missing over night after not coming back to U.A after his usual daily Patrols...

Flashback

It was the usual uneventful morning for Izuku Midoriya as he happily hummed while cooking his breakfast, two fresh eggs and bacon with Milk to further strengthen his bones for it to withstand the after effects of his Quirk

Izuku then finished his breakfast then brushed his teeth, as soon as he was about to go and wake Luffy, Law and his tardy classmates up, he saw a very unusual visitor entering their Dorms.

"Ah, Aizawa-sensei Good morning to you sir!" Izuku greeted to the sleep deprived Hero-Teacher

"There's nothing good about this Morning, Midoriya..." Aizawa oddly replied to Izuku who raised his brow at him, clearly confused

"What do you mean sensei?" Izuku asked and as soon as Aizawa told him the truth, Izuku couldn't help but cry and panic

Izuku along with Aizawa went to Law and Luffy's room and told Law about the situation, as soon as they received Law's cooperation to find the missing All Might, Izuku suited up and immediately went out to find his Idol...

Flashback End

"I Immediately went out as soon as we talked to Law-sensei but... I don't know where to start searching for All Might...!" Izuku thought as he continue to search the streets of the city, looking for clues or places All Might could've been

"First is Shigaraki Tomura's mysterious death, now All Might's sudden disappearance... All for One is definitely involved in this..."  Izuku calculated as he ran and ran through the dense streets, he was eerily calm despite all of this, he was a Hero now, he had to keep his cool from now on and he shouldn't let himself be led by his emotions just like what happened back then... being a Hero is a dangerous line of work and just by showing your emotions even for a brief second, you may lose your life.

"I need to find him... I have to... If I don't then..."

What's the point of being a Hero?

Law was about to leave the Heights Alliance when he was again called by Aizawa, saying that he was asked by Nezu to come to his Office, and Law currently is seated in front of the Furry Principal who's face was grim and eyes plagued by darkened eyebags

"It's good to see you Mr. Law, I thank you for responding to my call of help during our dire situation..." Nezu lowly said, he's normally a lively person(Animal?) and is usually sipping his tea but somehow Law saw that the Principal didn't brew any tea today, as he never smell any aroma in the air

"You must be tired Nezu-ya, why don't you take a break?" Law genuinely suggested to the Principal who only chuckled

"I'm still fine Mr. Law, finding All Might is a top priority right now, you shouldn't be concerned to me at a-" Nezu was about to finish what he's saying but Law quickly interfered

"What do you mean I shouldn't be concerned? I'm a Doctor, It's natural for me to be concerned about other people's well-being, and what I can see is that you need to rest." Law sternly said to Nezu who was left speechless

"Me, Mugiwara-ya and the other Heroes will find All Might for you, so you should just relax and trust us." Law said as he then stood up to leave

"Mr. Law, I cannot thank you enough" Nezu bowed to Law who merely looked at him over his shoulder, the Furry Principal then looked at Law's eyes as the two met each other's gaze intensely

"But I shall warn you Mr. Law, It is most likely that All for One is involved in this... All for One is a dangerous existence...  he has killed hundreds of Heroes and had acquired many different Quirks... we don't exactly know how strong he is now so If you're unlucky enough that you meet him, I suggest you to run..." Nezu lowly said to Law who only smirked at him

"What are you talking about Nezu-ya?" Law said to Nezu who was ultimately confused at what he said, Law could only smile as he recalled what Luffy had said on that day...

"I learned this from an Idiot... that even If you feel hopeless, even if you're faced with inevitable defeat...

A Pirate Never Runs from a Fight!

It was raining heavily, the whole city of Musutafu, Japan was covered by the dark clouds that covered the Sun, but during this time there was someone running through the streets like a possessed Madman...

Izuku Midoriya, a Hero-in-training and the Successor of One for All

He ran and ran, to look for the place where All Might could be, as he desperately used every single muscle and energy on his body just to find him

"It's no use... I can't find him!" Izuku was visibly frustrated, his whole body was covered by sweat and rain as he panted heavily, desperate to see his Idol again

"But just because I can't find him doesn't mean I should give up!" Izuku relentless will was reignited, he took a deep breath and closed his eyes to conserve his remaining energy

Izuku closed his eyes and cleared his mind as he focused, stretching his Haki all over the place as far as he could, he felt every living being that caught wind of his Haki that he exuded...

Cats, Dogs, Birds, and normal Civilians... every single living being nearby was sensed by his Haki, but not All Might...

"Maybe I'm still not proficient on using Observation Haki like Todoroki-kun is..." Izuku thought dejectedly as he slowly opened his eyes and looked around

He was in a very unfamiliar place, he saw that there were only few buildings nearby, as he continued to look around, his verdant eyes laid on a place that shook his being entirely...

What he saw was a very run-down Hospital... not just any other Hospital though, It was a place that deeply scarred him, and the place where all his Anxiety started...

"T-This Hospital was... the same Hospital where I was first declared as a Quirkless..." Izuku  thought as he gulped, his back was sweating heavily and his legs were shaking, it was visible how badly traumatize Izuku on seeing this place again...

Not long after being declared as a Quirkless, Izuku found out that the Hospital was closed down after that because the Head Doctor was practicing Illegal Medical Practices, The Doctor's License was revoked and the whole Hospital was shut down.

That was supposed to be the case but somehow, Izuku felt like he was about to throw up just by looking at the run-down Hospital...

"It's like an unknown force is pulling me into that place..." Izuku thought as he covered his mouth with his hands as he slowly walked into the Hospital, he could feel the eerie ambiance that the whole Hospital was exuding, It was a place where no Light could enter, a place completely covered by Darkness...

Izuku managed to enter the Hospital as he took a deep breath to calm himself down, he was forcing himself to even enter the place but now he's regretting it already...

Izuku saw that the Hospital was even at worse condition on the Inside... the Walls were vandalized and covered in holes while the Floor was taken over by the fauna and grasses, Izuku tried to look around and saw a stair that leads down to who knows where...

Izuku was unsure whether he should proceed to go down or not but his desperation to see All Might again won over him, he took the stairs down and saw nothing but Blackness...

Izuku walked around the dark room but the room is seemingly endless, he couldn't see the Walls because it was too dark, It was like he was blind...

He couldn't see nor hear any sound, It was like his sense of hearing and sense of sight was robbed out of him...

Izuku clenched his fist tightly, he already saw many horrendous things as a Hero but on the face of true Darkness, even he shows anxiousness and fear...

"My, My I did not know we had a guest today~" suddenly Izuku heard a chilling voice behind him...

"I recognize you... you're Midoriya Izuku from the Hero Class right? you're one hell of a Hero if you even give my Tomura a very hard time..." the voice was chillingly familiar... I mean how could he forget it...?

"Repelling Tomura's separate Invasions... and Infiltrating our Headquarters by yourself... you're very courageous Indeed! an Attribute befitting for a true Hero like you!" The voice said lowly, but loud enough for Izuku to hear, Izuku then saw someone... Illuminated by a spotlight standing behind him

The person was tall, his eyes were nowhere seen on his face, the only thing that's left recognizable on his face was his mouth, The person wears a black suit and was standing still, looking at Izuku's widened eyes with delight...

"Midoriya Izuku, will you kindly hand over your Quirk to me?" The person said in a whisper with a twisted grin on his face...

It was All for One... The Symbol of Evil.
