Angel: When Nine gets defeated, why would Izuka get his version of All for One? Not to mention that they don't see him again after he's defeated because he managed to get away. Not that the three would have been able to reach him in their state after the fight anyway.
Spoilers, but when Nine dies, nothing happens with the Quirks he stole. Because the person who killed him can't take them. So that leaves his Quirks gone. Plus Izuka has enough power that she doesn't need more. I doubt she would want All for One anyway. Similar to Overhaul, I don't like Nine for him terrorizing children, so I would not keep him alive either. If a villain does things to children, then they don't get very high praise from me. So it's not going to sway me changing their fates if I already dislike them.
The twins and Katsuki fell onto the ground hard as the fire tornado disappeared. Nine landed a few feet away. Izuku's sleeves, gloves, and upper torso of his costume were torn to shreds. Izuka's shoulder sleeves, gloves, and collar were gone from her own body.
It wasn't enough...even at 100 percent... He looked towards Katsuki, who was in the same state as the twins.
Damn it... Katsuki gritted his teeth angrily, struggling to get up. I bit the bullet and fought alongside them...and I still failed!
Anything we do...he's still standing... Izuka weakly looked up, noticing Katsuki standing in front of her.
"It's no use," Nine mocked while approaching him. "You simply don't have enough strength to defeat me. You would not survive the new world I will create."
"What new world...?" Izuku demanded while getting onto his feet. Izuka willed herself to stand as well. He was then knocked back by Nine's lasers.
"One ruled by power," He moved his hand to attack Katsuki and Izuka. Both of them grunted, Izuka falling towards the ground. Katsuki placed her arm around his shoulder blade to help her stand. "The strong will rule over the weak in my utopia."
"That's not gonna happen," Izuka snarled towards the villain.
"Same old crap," Katsuki growled before Izuku got caught by a dragon. He looked back in alarm before the same thing happened to him, and then Izuka.
"Labels like hero and villain won't be necessary," Nine glared towards the three of them. "Power will be the only factor that matters! That's how a true superhuman society should be structured!"
Izuku let out a small growl, as he, Katsuki, and his sister were ensnared by the blue dragons. "Sounds like something a power-hungry madman would dream of!"
"That's never gonna work, moron!" Katsuki used a mini explosion.
"You think we'll let you do that? Not a chance!" Izuka glared down at the villain. The three blue dragons went up into the sky, using some of the ruins to further injure them.
"If you attempt to get in my way...then you'll have to be eliminated," Nine clenched his fists to make the dragons squeeze their grip into the three.
Gotta think! What would All Might do? Hanta and Ochaco were unconscious nearby. Katsuki gritted his teeth while trying to break out.
I'm not letting some lunatic beat me! Katsuki gave a small growl.
We can't give up now! Not when he's hurt so many people, including all our friends! Some were unconscious and couldn't get up, while others tried.
Think...come on!
I won't lose! Katsuki was trying to think of something...anything.
We can't just sit here! Izuka clenched an angry fist.
Think...
"MR. DEKU! MS. CALLISTA!" A familiar voice shouted, getting their attention.
"BAKUGO!" Mahoro cried out to them.
"WE BELIEVE IN YOU!" Katsuma was trying to heal the unconscious Mezo. Mahoro was holding his head.
"PLEASE DON'T GIVE UUUUUUUUUUUP!" The two siblings shouted in unison.
Izuku's eyes widened while Nine gave a small smirk. "There you are," He stepped to the kids, who gasped sharply. Katsuki gritted his teeth as they couldn't move to stop him.
"Kacchan...Izuka..." Izuku's weak voice got their attention back. "I've got a crazy idea..."
"Huh?" Katsuki murmured and Izuka blinked, gasping.
"...Are you sure, little brother?" She asked quietly while glancing up at him.
"There's only one way we can stop him..." Izuku answered, Katsuki a bit out of breath as he realized what the twins were getting at. Mahoro and Katsuma sat bravely to keep helping Mezo as Nine approached.
"I wasn't born with this power." Izuku remembered Toshinori saying while reaching out his broken, bloody hand. "It's a sacred torch that was passed onto me from someone else. I can transfer my power to another."
Katsuki gritted his teeth, closing his eyes. Izuka shed a small tear, sighing. He looked up at his former childhood friend, knowing that he was sacrificing a lot...
"Please...Kacchan...Izuka..."
Izuka slowly reached out her hand, trying not to tear up.
"You were right. A hero has so much to protect in this world," Toshinori's eyes glowed while Izuka's hair flew around. "Which is why we will defeat you!" His arm was muscled up while Izuka's power grew.
"I'm just a child, and I know people are worried. But...that's also why I'm here. Just because the odds are against me...doesn't mean I won't fight back!" Izuka declared furiously at All for One.
"Deku..." Katsuki reached out his hand as well.
"A real hero...will always find a way for justice to be served!" All Might then laid out multiple punches onto the Nomu at the USJ.
"Guys..." Izuka coughed out while reaching out as far as she could as well.
"I will protect you with my life, as you did for me," Toshinori spoke up softly and tears appeared in her eyes.
"A way...to protect them," Izuku murmured while the kids still stood their ground. Katsuki strained himself to reach Izuku.
"A way to victory..." Katsuki grunted out as Nine was getting closer.
"A way...to earn their respect!" Izuka managed to muster as their hands missed each other.
There is no other choice! All of them thought, knowing that they had to do it if they wanted to save the island. Their fingertips touched Izuku's blood before they all touched hands. A glow came from their hands and once they did, there was a huge explosion that broke them free. Nine looked up in alarm, holding up a shield. The three dragons exploded and Nine moved back the shield, seeing smoke. There were three shadows in the distance, one of them their hair flying around.
Katsuki slowly got onto his feet. "After this...will you still be able to use your power?"
"I don't know," Izuku confessed while getting up as well. "But...All Might was able to protect us with its embers," He gestured to his chest as he could still feel the embers within him...for now. "Even after he passed the Quirk to me..."
Izuka moved one foot in front of the other, clenching her fists as she got up. "Izuku...no matter what happens today...you're a hero," She told him while small white stars surrounded her back.
"What did you do?!" Nine demanded from the trio, electricity coming from his hands.
Red veins surrounded all of their bodies. "With Triple..." Katsuki started off, something forming from Izuka's back.
"One for All..." They all stated together.
Izuku opened his eyes, green sparking from them. "We'll save everyone!" His hair turned a lighter blue.
Katsuki looked up, his eyes flashing with fire. "We'll beat you and win!" His hair got even more spiker, and also more brighter.
Izuka opened her eyes, light purple emanating from them to surround her eye lids. "We'll earn their admiration!" Her back then sparked as big wings made out of her shooting stars formed, lifting her up off the ground. Then she gave a small twirl as her hair got lighter as well, moving above her head just like Nine's. The trio then stared down the villain, now sharing One for All! Energy was sparking from all of them as Izuka continued to flap her new wings.
Nine gritted his teeth angrily. "Why won't you weaklings die already?!" He shouted while making a fire tornado, lightning sparking from it. This sent out a strong gust of wind towards Mahoro and Katsuma, who held onto Mezo while squeezing their eyes shut.
The trio looked up at the tornado in silence. "This is the end of your dream, Deku," Katsuki gritted his teeth a little in worry. "You're gonna be Quirkless again."
"But that's fine. I have to do this," Izuku declared as he wasn't fazed. "I'm sure that All Might would agree...since you were the ones I gave it to. And I know that Galaxy and One for All can't be good together either."
"Going up against this monster? I know I'll be okay with you guys fighting by my side," She glared at the fire tornado, still flying between them. The two reached out to grab her hands, Katsuki in particular squeezing it tightly.
"You knew about our secret and kept it to yourself," Izuku pointed out to his former childhood bully. "We've always tried to be the same hero! So if it's you..."
"All Might's awesome!" Katsuki gushed with a big smile, watching the hero on TV. "He's crazy strong!"
Katsuki let go of Izuka, clenching his left fist that caught on fire.
"Even when things seem impossible..." A teary-eyed Izuku pointed at the screen. "He never gives up!"
Izuku clenched his right fist as a blue flame surrounded it.
"Even when things seem like the end, All Might always brings hope. He's the greatest hero in the world..." Izuka sobbed after telling her family about her Quirk. "Because he's the shining one we need..."
Izuka let out a yell as her whole body was surrounded in purple flames, her power emanating off of her.
"No matter what bad guys are in front of him..."
"HE ALWAYS WINS!" Katsuki screamed while recoiling back his flaming fist, rocks flying up.
"No matter what trouble is in his way, he always..."
Izuku moved back his own fist. "SAVES EVERYONE WITH A SMILE!" His power sparked off of him.
"No matter what, you could never forget him because..."
"HE'LL ALWAYS BE REMEMBERED AS OUR SYMBOL OF PEACE!" Izuka shouted angrily while swinging back her arms, bright purple flames surrounding her arms. Nine held up his arms, growling.
"You'll never...DEFEAT ME!" He yelled as the two boys stomped their feet in front of them, powering up their fists. Izuka's arms continued to burn as she prepared herself as well.
"DETROIT..." An aura of purple, yellow, and blue surrounded all of them. "COMET PUNCH SMASH!" They all screamed together while punching the air, sending out a huge fire light to the sky. It hit the tornado while they all braced themselves, their bones breaking. The three all yelled while keeping up their power, and then their light got bigger against the tornado. Suddenly, the darkness exploded and light came instead, raining down shimmers. Mahoro and Katsuma looked up in awe as the sparkles flew...the little flames formed into stars.
"No...they couldn't," Nine gritted his teeth at his opponents, baffled by their power. "What is this power?!" The three held their stances, their arms broken. Their power was still sparking as they looked up at Nine. "I won't let you block my path! Never!"
Once they put down their arms, Katsuki flinched in pain. Izuka slowly descended down between them, placing one foot in front of the other. Once she did, sparkles flew up around them in a circle. In an instant, Katsuki could stand up just fine.
"Hah? You can heal now?" Katsuki wondered while glancing at her.
"One for All certainly does have its wonders combined with Galaxy," She wasn't even fazed by this ability. Suddenly, shooting stars flew around the boys' broken arms to try and heal them.
It's just like with Eri. If we move fast enough, she can heal our arms before they get worse.
"Kacchan, sis, let's go," Izuku grunted out to the two.
"Huh? I thought I told you not to give me orders!" Despite him saying this, he still lunged forward with the twins.
"Don't get in my way!" Nine sent out more of his blue dragons, Katsuki leaping over them while firing an explosion. He soared around them, firing off bigger blasts to incinerate them. He looked back as several chased him and flew away. Izuka spun around elegantly, throwing even stronger shooting stars at the dragons, watching them explode into pieces. She then flew above a head, swinging down a Jupiter Wind, the wind slicing the head in half. Izuku reached out his leg to kick Nine, who dodged out of the way. Izuku flew backwards from the lasers, zipping around and jumping to avoid them. Nine continued attacking him, giving Katsuki a chance to fly in with a big explosion. As Nine was flying, Izuka flew in past the flames to give him a big Mercury Blast. He held his arm in pain as he fell, the three landing as electricity surrounded them. Katsuki gave off a big explosion, skidding his feet to push his power as much as he could. Izuka joined in to give off big flames and ice, further pushing an attack to Nine. Another explosion went off, Izuka catching Katsuki and flying upwards. Izuku then crawled using his electricity, zipping quickly to Nine. He spun into an attack, Nine attempting to block him with a big air shield. Izuku kicked at the shield, breaking it and causing another blast. Nine was shot into the air, met by Izuka, who spun around with flames surrounding her feet. She then kicked him towards the ground hard as he fell into a landslide, Izuka kicking at him repeatedly with her flamed feet. While she did so, the boys jumped in to follow her, Nine looked up just as the two attacked.
This is it...the last one... Izuku could feel that this would be the last time One for All would be his Quirk... It's over now... Their whole bodies were surrounded in flames as they prepared the final attack. Katsuki held out his hands while Izuka swung up hers above her head. This is my final...SMASH! Izuku swung back his leg as Izuka spun around, her power storing up. Nine could only look up as Izuku kicked him hard. Katsuki reached out his hand to fire off an explosion while Izuka swung down her hands, giving off a huge flame to knock into Nine. A light shined from above...as the smoke cleared and Izuku felt the ember...as it slowly died out. All of them had their eyes closed, Izuka's wings having disappeared, and One for All was gone from all three.
Goodbye...One for All...thank you...
