A/N: Save Them!!!
At the League of Villains' hideout, Tomura, Kurogiri and the Vanguard Action Squad are entrapped in the mysterious black liquid...
Yin: No!
Like what happened to Bakugo, Yin were also trapped and taken into the black liquid!
All Might: YOUNG HAMADA!!!
Shigaraki: Looks like it's bye bye for now, All Might.
All Might: NO YOU DON'T!
All Might and Gran Torino attempt to stop them but the mysterious black liquid teleports Tomura, Kurogiri and the Vanguard Action Squad away from the hideout. Bakugo and Yin were taken along with them.
All Might: No....I failed...NOOOOOOO!
Kamui Woods: No...We couldn't stopped them...
Kamui Woods begin to mulls over his failure in restraining the League of Villains. Edgeshot comes over to comfort him.
Edgeshot: Don't worry... It's not your fault. We could not do anything either.
Four Nomus had appeared and attack All Might. However, All Might defeats the Nomus with Oklahoma Smash.
Edgeshot: All Might! Get outside! There is still a chance to save those two boys!
All Might look over at the other Nomus that appeared.
Kamui: We'll take care of them! Just go!
-Later-
Outside the hideout, Naomasa along with Endeavor and the Police Force continue battling the dozens of Nomus and have the upper hand. All Might appears but noticed Endeavor and Naomasa had everything under control decides to leave the rest to Endeavor.
All Might: (Hamada-kun! Bakugo-kun! Before I reach my limit! I will save you both!)
-Meanwhile-
From broken buildings to fire in a wastelands. Izuku, Mikoto, and the others were hiding behind a giant rock as All For One had appeared from the darkness.
The Killer Aurora had spread everywhere....
None of them move from fear seeing this man. Their faces pale as Yin's. The Aurora glowed red from blood and death.
All For One's deadly aura utterly terrifies the kids. Izuku starts to realize who the man above them is since All Might told him about All For One.
Except this was no man...
This was a monster...
Izuku is in utter disbelief that he might have to eventually face such a monster in battle.
AFO: Shigaraki finally started thinking and making decisions for himself.
Deku:....
Mikoto:....
AFO: I wish you hadn't got in his way.
Haru/Sylvia/Kenji/Souta:....
Shouto/Kirishima/Momo/Iida:.....
-Deku's Pov-
There was even no time to look back...
It was the work of an instant.
What happened...didn't even take a second...
Even so...that man's spirit...
Gave us hallucinations of DEATH...
All Might told me that one day I will have to fight against this great evil...
Tomura...Was he talking about Shigaraki...?!
But what is this...?
This is not true, is it, All Might....!
That's...All For One...!
AFO: Now then...shall we do it?
-Third's Pov-
Suddenly, Katsuki and Yin materializes from the black liquid in front of All For One, which catches the attention of Izuku's group.
All For One apologizes to Katsuki as Tomura, Kurogiri and the Vanguard Action Squad materialize from the black liquid as well.
AFO: You must be Bakugo and Hamada.
Bakugo: Hah?!
Yin: W-What do you want from us?!
AFO: I wanted to apologise for this sudden upturning. But...I wanted to see you could try to escape again...
All For One sees that his apprentice, Tomura, has failed again. However, All For One is neither angry nor disappointed with Tomura and encourages Tomura to try again since he still has the Vanguard Action Squad and Bakugo and Yin whom he deemed important.
He then looks at Yang Hamada.
AFO: You must be this boy's father? Correct.
Yang: Yes. That would be me. Sorry for the late response. I had to be held in confinement~!
AFO: Oh..There is no problem...But...
Suddenly, AFO appeared at Fast Speed and grabbed Yang by his neck hoisting him the air.
Yin's eyes went wide in shock. Bakugo backed away in horror.
Yang: W-What are you doing?!
AFO: I have no time for weaklings like you. You strive to have your son be a villain but you couldn't do that yourself. So instead you physically and verbally abused him and his mother for years.
Yang: S-Spare me please.
AFO: I have no time for weaklings like you who used their authorities for power.
Suddenly, AFO's hand begin to glow and Yang Hamada let's out an soul-shattering scream.
Yin: What the....
The torture ended for a couple of minutes before the struggling man stopped moving.
Yin couldn't believe his eyes.
AFO: Such a shame. He was so pitiful to the end. At least his quirk is useful.
Yin: N-No way...(He stole his quirk.)
He looked down at the man who was no longer his father. He wasn't moving at all...Is he...?
All For One implores Tomura to continue trying as many times as he likes since everything is for his sake.
AFO: This child... Because you judged has a important piece...If he had, he wouldn't have spoken so freely.
Shigaraki: Sensei...
-Meanwhile-
Mikoto: W-What's the plan Izuku?
Deku: We're about six or seven meters away from Kacchan and Hamada-kun.
Mikoto: So...?
He gestured for Izuku to continue.
Deku: With Full Cowl. Maybe I could reach them in a second.
Izuku figures out that the enemy has not realized their location and decides to do something to rescue Katsuki; Izuku plans to use One For All Full Cowl, jump towards Katsuki and Yin then run away but he quickly dismisses the plan after seeing that escape is impossible.
So Izuku attempts to move since the opportunity to save Bakugo and Yin unlike last time. However, Tenya stops Izuku from moving.
Iida: Wait...
Kirishima: What is it?
Suddenly, they all felt a rush of energy and saw All Might appeared. He rushed to attack AFO who stopped the punches with his own hands.
The force blasts everyone nearby away.
Niko: Whoa! I'm flying~~~! Kehehehehe~!
Shigaraki: SHUT UP NIKO!
Niko: You shut up. Or do you want to me to give you a 'hand' with that~!
Shigaraki: You little BITCH!
Niko: *Trolls Face*
Yin: No way...
Bakugo: (He held All Might back with his bare hands...This guy is the villain's boss!)
AFO's arms grew massive as he spoke to All Might.
AFO: There's so much to do...It'll be tough for the both of us~~~!
All Might tries to punch him off but was blown back by the force. All Might was thrown around three multiple buildings.
Bakugo/Yin: ALL MIGHT!!!
AFO: Even without your worry, he won't die from something like that...
Bakugo and Yin looked around to see the villains all appearing around them. Even the real Toga Himiko showed up.
Toga: Man, I can't believe I missed all this excitement.
Dabi: Ugh. At least you're alright.
Toga: Awww. You worried about little old me~?
Dabi: Not really.
Toga: *Pouts*
Yin: We're surrounded.
Bakugo: *Grins* Shit...What a pain.
Yin: (What are we going to do now?)
-Meanwhile-
Mikoto: Izuku. This is now or never. We all have to act.
Kirishima: Yeah Man..we need to save those two.
Deku: Okay. Now that you all now we have to do.
They all looked to see Bakugo and Yin dodging all the League of Villains attacks. Their efforts of using their quirks are in vain. Twelve again at two. At this rate, they'll be captured again.
Deku: If we save Kacchan and Hamada-kun...then All Night's power can reach his fullest.
So Deku out his plan into motion.
Deku told Kirishima and Iida to gather together with him. Mikoto doing the same with Sylvia and Kenji. Then they'll propelled themselves into the air. Mikoto using his snow quirk to slide them up and Deku's using his quirk along with Iida's Recipro Burst.
Then with Kirishima's hardening to protect himself.
Kenji bat wings appeared as Sylvia uses her fire to burst her and the other two boys up.
After Izuku, Mikoto, Sylvia, Kenji, Tenya and Eijiro burst through the wall, Shoto creates an ice ramp. Mikoto helps him power it up to make it high as possible; Izuku, Mikoto, and the others jump off Shouto's ice ramp and head into the sky above the battle between the League of Villains, Katsuki, All For One and All Might.
To cross the battlefield where the villains can't reach him.
-BAM-
All For One sees the group and attempts to attack them, but All Might intervenes by punching his arch nemesis.
Bakugo and Yin looked up to see the others in the sky.
Yin: Is that...?
Bakugo: No way...
Kirishima: BAKUGO!!!
Mikoto: YIN!!!
Both of them hold out their hands to them.
Both: GRAB ON!!!
Bakugo and Yin wasted no time.
Shigaraki: NO YOU DON'T!
Tomura tries to stop Katsuki and Yin, but Katsuki uses his Explosion and Yin used his spirits to launch theirsleves towards group. Yin manages to grab Mikoto's hand while
Katsuki grabs Eijiro's hand.
Bakugo: *Smirks* You stupid of something?!
Yin: Class Rep...
Mikoto: I told you I would save you!
Yin: Thank you and.......I'm sorry.
Mikoto: Eh?
Sylvia/Kenji: ???
Haru: They did it...They managed to get them...
Souta: What an relief.
Momo nodded.
Shouto: Now our chance. Let's go.
The four wasted no time and made their way to escape while the villains were occupied.
Meanwhile, down below the villains were shock at what was going on. Their prisoners were escaping.
Shigaraki: You bastards! You show up everywhere ruining everything!
All Might couldn't help but feel relieved. He sees Bakugo and Hamada being taken somewhere safe with the others and Mitsuo-kun escaping with the rest. He didn't have to worry anymore...
All Might: Thank Goodness.
Niko: GET BACK HERE!
Niko summons his dark shadow claws to launch himself in the air.
With help from Magne's quirk, Mr. Compress and Spinner follows closed behind trying to get their prisoners back.
Niko: MIKO-CHAAAAAAAAAAAAN!
Mikoto: *Yelps in fear* Niko?!
Niko: COOOOOOME HEEEERE!!!
Niko tries to reach him but he and the other two villains ends up hitting MT. Lady in the face.
*SLAM*
Mikoto: MT. Lady!
Niko: Ow...
Niko, Spinner, and Mr. Compress fell down to the other villains as Mikoto laughs at Niko and gave him the middle finger.
Mikoto: EAT GROUND YA BITCH!
MT. Lady: Go home you crazy kids...
She fell down to the ground as the students finally made their way out of the Villains Hideout.
Shigaraki: NOOO!
Juurou: Shit...
Miyumi: Fuck...
Toga: *Pouts* They got away...
Shiromi: No fair...
Teddy: All that fun for nothing....
Magne: We can still make it!
Twice: Let's try again.
However, they were all cut off as Gran Torino appears and whacks them all.
All Might: You're too slow!
Gran Torino: You're too fast!
Before Tomura can attack Gran Torino, he along with the Vanguard Action Squad is magnetically pulled into Kurogiri's Warp Gate.
AFO: Kurogiri...Get them out of here...
Kurogiri: Of course, Master.......
Niko: Aww man...
Himiko: No! I don't want it to end!
Remy: Fuck...I wanted to torment them...
Shiromi: No more fun...
Teddy: This blows...
Himiko, Niko, and the other villains are sucked into Kurogiri's Warp Gate with Magne being thrown into the portal courtesy of Sensei, teleporting them away.
As he is being sucked into the Warp Gate, Tomura calls out to his teacher concerned for his safety.
Shigaraki: Sensei! NOOO!!!
Before Tomura teleports away, All For One tells Tomura to continue the fight.
Tomura and the unconscious Kurogiri are teleported away by the Warp Gate, causing the portal to disperse.
All Might: Gran Torino. You get out of here too.
Gran Torino: What?! I'm not going to leave you too-?!
All Might charges at All For One, but All For One uses his Transmission Quirk to teleport Gran Torino in front of him, using the elderly hero as a human shield which causes Gran Torino to take All Might's attack instead.
All For One then expresses his hatred for All Might as he is the one who brought down his comrades in the past and while he descended into darkness, All Might rose to the top as the Symbol of Peace.
All For One prepares to fire his blast wave move, intending of blowing away Gran Torino and All Might at the same time. However, All Might pulls Gran Torino away and uses Detroit Smash to cancel out All For One's blast wave move.
All For One sees that his destruction of the city has brought chaos and decides to put the innocent civilians in danger so that All Might won't be able to fight at full strength.
Furious with All For One's sadism, All Might grabs his arm while throwing Gran Torino away for safety.
AFO: So...This is where it all ends All Might...Just you and Me...Just like it should've ended all those years ago.
All Might's grin went away bringing it into angry look.
This was the final battle between them...only one of them would be the victor...
All Might: All For One...The despicable crimes you have committed and for his misanthropy. I swear...I WILL BRING YOU TO JUSTICE!
PLUS ULTRA!
