Chapter 140: Victory and Becoming the U.A. League
The fight begins as Black Might dodges the leaders oncoming stampede before attacking with one for all and using Detroit smash on the leaders. The leaders then use their quirk enhanced body to try to kill Black Might, who then dodges quickly and decided to go beyond plus ultra. Black Might then contact the predecessors of one for all and told them to activate the machine so he can defeat the leaders of the Band of Massacre. However, Daigoro told Black Might that the machine was destroyed because of Fyet and Fajin's recent fight, so En needs to rebuild it before they can activate it, causing Black Might to pout before deciding to go beyond anyway, which also caused the users to become shocked. Black Might then use too much of one for all to fight the leaders, which works at first until his hands became damaged after he unleashed one for all. Soon, the Peanut Gallery intervene and work together to fight the leaders while Creati and Battle Fist check on Black Might, who was speechless until Battle Fist ask him if he's alright before calling him Deku, which made Black Might furious as he screamed that his name is not Deku. After Battle Fist knocked Black Might unconscious, she and Creati told shocker and Shroom to take him into a police car so they can take him back home after dealing with the Band of Massacre, causing the boys to say right before taking Black Might into the car before joining everyone in their fight against the band of Massacre. Soon, the U.A. League joins the fight along with Lydia until the leaders breaks down. They then furiously tell the heroes that they will win for All for one before telling The Anti-hero Squad to come out with Kingpin just in time as Nejire Chan, Shoto, and their siblings combines their super moves together and defeat the leaders in one shot. The heroes then glare at Kingpin and the squad before Pinky coldly told the villains that they're next.
Nelson told Kingpin to attack, which caused Kingpin to charge at the heroes before creating shockwaves by slamming the ground. Ryuku and Majestic then work together to attack Kingpin while their comrades fought The Anti-hero Squad until they finally surrender and beg for mercy. Meanwhile, the Peanut Gallery work with the U.A. League to fight Kingpin, but it's not easy since he's similar to Gigantomachia until most of the league, especially the parents of Kacchan, Ingenium 4, Red Riot, Froppy, Uravity, and Pinky got knocked out as they rush to their parents' side and told their siblings to keep fighting. Meanwhile, Black Might was getting scolded by the previous users for being reckless, causing him to angrily reminded them that he got rewinder guns for a reason. Nana then bended down and told Black Might that she's extremely disappointed that he is turning into a rebellious teenager, causing Black Might to get angry and demanded who does Nana think she is before saying that she's not his mother before storming out with his hands in his pocket after throwing a fork at Daigoro when he tries to talk some sense into him. After Black Might wakes up, he saw his friends becoming desperate to defeat kingpin, which caused him to get mad and drank a growth serum to become a giant much to everyone's shock, especially the Peanut Gallery. Black Might then told everyone that he can handle Kingpin by himself, causing Kingpin himself to laugh evilly before motioning him bring it on. Black Might then march toward Kingpin despite his comrades' protest and prepares for a fight.
Black Might starts the fight with smokescreen before using double team to blast one for all. However, Kingpin dodge them and kicked Black Might into a building, which caused it to crumble down before Black Might flew into the air to use Chicago smash on Kingpin multiple times until the predecessors of one for all appears in front of the Peanut Gallery, and told them that Izu's rebellious phase seems to have gotten worse after they intervene the fight against the leaders, causing Ingenium 3 to ask what should they do and Creati to ask when the rebel phase will be over so everyone can have Deku back and Black Might to be gone. Suddenly, everyone got out of the way as Black Might flipped Kingpin over and restrained him before meditating into the vestige world. Once inside, Black Might ran to the invention and use one for all to quickly rebuild it before activating it. Afterwards, Black Might use 100% of one for all to attack Kingpin with everything he got until Kacchan and Pinky say that they need to stop this before Deku gets himself killed, causing Eraserhead to stop the Peanut Gallery before using his quirk to deactivate Black Might and Kingpin's quirk, leaving Kingpin confused and vulnerable as Black Might took the opportunity to use MMA to finish the fight. After Kingpin's defeat, Black Might shrunk himself and confronted his comrades for not letting him handle the leaders by himself, causing Uravity to tell him that he was going to die, which also caused Black Might to get upset. After Gevauden call Black Might Deku, Black Might had enough and chew the Peanut Gallery for their constant meddling before saying that they think they can act as if he was defenseless and weak, but they're just kids like him, causing his classmates, class b, the big 3, and Mei's feelings to become hurt as Creati and Ingenium 4 dragged him home with their teammates behind them as Black Might starts screaming at them and say that he hates them, which caused Battle Fist to knock him unconscious. Imengine then told the Peanut Gallery that it's ok because he's been this stage when he was 13 years old, causing Froppy to solemnly say that Deku is nine before she and everyone else glared at Anima before saying that she lied to them because she say that Deku's rebel phase will be over if they just wait, which caused Special to tell the kids that everyone has a rebel phase in life before theorizing that they must be the reason why he's acting this way. Soon, the siblings took the Heights Alliance Peanut Gallery far from Deku and whisper what Special told them, which caused Creati and most of class b to start crying until Deku wakes up and angrily get into a car to pout as he recalls flashbacks of himself vowing to prove to his friends that he's not weak, defenseless, or just a simple kid who does things recklessly. Naomasa and Sansa then get into the car and drove Deku home as he starts crying. After the Heights Alliance Peanut Gallery left, the siblings talked to the U.A. League, who then say that since they did a great job being the first youngest pro heroes, they want to give them the U.A. League's name, which caused the siblings to smile briefly but became sad as they think about Deku.
