AN: Alright another chapter done! Thank you for reading my story so let's just jump into it!

Final Fight

Two minutes that's all they needed, but they knew in those two minutes Vent could kill them all. "Guys be careful" the three nodded and flew towards Vent.

"Bring it! I'll fight you all then I'll kill you saiyan" Himari was the first to reach Vent, blocking her initial attack. From behind her Uraraka and Bakugo appeared splitting up and attacked from both sides, kicking Vent causing him to fly back.

"I see you two have trained to use your Ki, you are no ordinary humans" Vent smiled.

"That's not the only thing we can do" Uraraka activated her quirk on a giant boulders making them float beside her. Using her Ki she flung the rocks at Vent at a high rate of speed and at the very last second she deactivated her quirk allowing the full weight of them to crash into Vent. This buried Vent in a small mountain of boulders, "Bakugo! Himari! Do it now!"

"Not a bad plan you have here round face" Bakugo said appearing above the mountain of boulders. "Howitzer Impact!"

"Not bad at all, Planetary Devastation!" Both attacks bombarded Vent engulfing him completely in lime green and red fire ball.

Landing back with Uraraka, both of them looked at each other and smiled, "Nice teamwork guys"

"Not quite good enough" a voice was heard from within the fireball. "HAAAA!" a ruby colored aura erupted from the flames pushing the blast away. "Not too bad but the only one doing any real damage is the female saiyan. So let's take care of her first"

Disappearing from view Vent appeared to teleport, "Where the heck did he go!? Himari! Behind you!" Bakugo yelled out but it was too late.

Vent's hand glowed red as he punched Himari hard in the back, "Himair!" Uraraka yelled as she spit out blood as she fell to the ground reverting back to her base form.

"Y-You bastard" Himari grunted. 'My spine it's broken...I can't move my body'

"You have so many injuries! How are you still so strong!?" Bakugo yelled out.

"Simple" Vent pulled the spike from his chest. "Because I was born weak, in my family power means everything. If you are weak you die, if you are powerless you die. I had to train every second of every day just to be recognized by my family. I've conquered entire galaxies but was that enough for him? No it was never enough, that's why I need that stone. Strength is the only thing that matters and anyone who gets in my way…"

Appearing in front of Bakugo, Vent jammed the spike into Bakugo's shoulder, "...Will die" pushing Bakugo to the ground he pinned him to the ground using the spike.

"Bakugo!" Uraraka yelled as she flew towards him trying to help him out, only to have Vent blast her away.

Rolling to a stop Izuku couldn't take it his friends were getting, as Uraraka got up Izuku noticed she had cuts over her body. "Uraraka! Vent you bastard" 'Damn it come just hold on just a bit longer'

Landing in front of her Vent raised his hand towards her, "Are you watching saiyan? You get to see your little girlfriend die" his laughter echoed through the battlefield as he charged up.

'Mom, Dad, Eri, I'm sorry…' Looking straight at Vent, Uraraka smiled one final time accepting her fate. Suddenly there was a flash of golden light, blinded from the gold Uraraka couldn't see what was in front of her. After a few seconds she saw Izuku in front of her as a super saiyan 3 and a few meters away was Vent on the floor. "D-Deku"

"You did good Uraraka but now it's time to get out of here. Get those two out of here, I'll handle the rest" Izuku smiled

"Y-You better not die a second time Deku" Izuku nodded as she took off picking up Himari and Bakugo.

"Time to end this Vent" Izuku let out his aura.

"Something we can agree on" once again Vent transformed into his ruby form.

Bunker

"Alright! Midoriya is back in this!" Iida cheered.

"Heck yeah now Midiri can beat this guy!" Mina said, jumping with excitement.

"He won't win" a voice behind them said, turning around they found Dende walking into the bunker.

"Dende! What do you mean he's not going to win?" All Might asked.

"The super saiyan 3 form is powerful but it comes with a drawback, it basically destroys his body when he's in that form. That form burns too much energy and is usually used to end fights quickly but with an opponent like Vent that's not possible. You saw it once already, he had to charge up, that was his body telling him he had to stop" Dende explained.

"What does that mean for Midoriya?" Shoto asked.

"At the rate he's going to run out of energy again and that's when Vent will kill him" Everyone's eyes went wide when Dende said this.

"Is there anything we can do?" asked Iida

"Yes, we can send you All Might to back him up" said Dende

"M-Me? But I can't, my power is gone and I can't fight in this form" All Might said surprised.

"Ah but that's where I come in, you see like the one you call Recovery Girl I can heal any injury no matter how severe. I know you go into your buff form for a split second so your power is still there just very weak"

All Might put down Eri, "You mean!" Dende nodded.

"Yes be it for a short while I can restore you to your prime. What do you say?" said Dende with his hand out.

"I'll do it," All Might said, taking his hand as soon as he did All Might's body began to glow and grow in muscle mass.

With Izuku

"It seems I should have taken care of you first, well no matter. This will end differently this time, I'll make sure to kill you first" Vent launched himself towards Izuku, blocking the attacks Izuku was being pushed back.

Back and forth the two went, they were moving so fast that the camera couldn't keep up with them. 'I need to end this now, this form won't last much longer'

"HAAAAAAAAAAAAAA!" with a powerful yell Izuku managed to hit Vent hard in the stomach making him spit out blood. While he was hunched over Izuku raised his hand in the air and with a double fist strike to the back he sent Vent flying towards the ground. "I'll put everything into this last attack!"

Regaining his composure before he hit the ground Vent looked up to find Izuku flying towards him at a high rate of speed and smiled, "You truly are amazing Izuku Midoriya! This fight is over…for you at least"

Izuku pulled his arm back at the last second and threw a punch causing a massive explosion of energy that sent pieces of the earth flying in every direction. Uraraka and the group watched from far away as the massive explosion was felt from where they were. "It's over," Uraraka said, hanging her head.

"D-Did Izuku do it! Did he beat Vent?" Himari asked as she was being held up by the two.

"N-No, Deku lost, we all lost," Bakugo said gritting his teeth.

As the dust settled Vent was holding back Izuku's fist but he was in his base form, "Too bad, it looks like you drained your Ki faster than last time. If I had to say it was probably all those injuries not to mention that hole on your side"

"W-What hole…" Izuku felt a burning sensation from his right side, looking down Izuku saw Vent had fired a beam through his side.

"Goodbye Izuku Midoriya" pulling Izuku down, Vent hit him hard in the face, sending him flying.

Broken and bleeding Izuku laid on the ground barely holding on to consciousness in a crater of his own creation. 'I-It's over he's won'

Landing beside Izuku, Vent saw that he was still alive, "My god you saiyans are hard to kill. How much is it going to take to kill you once and for all!" suddenly the glow of ruby red disappeared from Vent's body. "Oh it looks like I can no longer keep up that form"

Izuku laughed, "Hahahahahaha!"

"What are you laughing at, has being at death's door made you historical?" Vent wondered.

"N-No" Izuku said, coughing. "Y-You will never kill what I am"

"What a worthless excuse of a saiyan? Please" said Vent.

"A symbol, heroes rise and fall but their legends live on, soon it will inspire people. Cut off one head two shall take its place…It will be only a matter of time when someone stronger than myself will take you down" Izuku smiled.

"Is that so? Then maybe I should just blow up your planet" Izuku's eyes went wide. "Actually no I can't, I still need the gemstone. If I destroy your planet now I will lose my chance for greater power. Oh I know, I will have my men scouring this planet slaughtering the population until I find what I'm looking for"

"Y-You bastard!" Izuku tried to get up but couldn't find the strength to do so.

"But first I need to take out the most troublesome ones. Starting with you, then the female saiyan" Vent pointed a finger at Izuku ready to fire a death beam at him.

With Uraraka a few moments ago

"He-He needs help!" Uraraka yelled out.

"I know but we can't do anything, he's just too strong" Uraraka said, feeling useless in this situation.

"Fear not young heroes!" a voice said from behind them. Looking back Uraraka and Bakugo's eyes went wide. "I am here!" All Might said striking a pose in his hero costume.

"All Might!" they both yelled out. "How!?"

"It's all thanks to Dende right now I'm back in my prime, although this power is not permanent" All Might explained.

"All Might! You need to get to Deku fast! He needs help" Uraraka pleaded.

"Don't worry Uraraka, this time I will make it in time!" and with that All Might left everyone behind taking off at top speed towards Izuku.

'Please All Might save Deku'

With Izuku

A red beam appeared on the fingertip, "It's been fun kid but this is goodbye" just as Vent was about to fire a voice was heard.

"Delaware SMASH!" All Might's giant fist hit Vent sending him flying. In front of Izuku was the once number one hero.

"A-All Might? How?" Izuku looked up to find All Might offering him a hand up like he did when All Might fought All For One.

"It's a long story but right now we don't have much time. Do you have a technique that can take him down?" All Might said pulling Izuku to his feet.

"...I do have one, The Spirit Bomb," Izuku said, placing his hand over the hole that Vent made in his side. Izuku put up his hand towards the sky. "It's going to take 5 minutes to gather enough energy to charge, so I need you to buy me some time. Considering how badly he beat me up...never mind you'll be fine"

"Wait I don't like that pause…" All Might said as a drop of sweat appeared on his forehead. "No matter I'll do what I can put you need to finish this, ha this reminds me of the time we fought the Nomu in the USJ"

"Yeah good times huh. Now go and All Might...Don't hold back" All Might nodded as he jumped out of the crater to face Vent.

"Now I need to focus, feel the energy around me, the plants, the animals, everyone please lend me your energy" Izuku said, closing his eyes. Above Izuku a glimmer of blue energy began to swirl around until it created a small ball. As the tree's blew in the wind and the animals grazed the land their energy began to flow out of them in a glistening blue wave that flew across the sky towards Izuku.

In the Bunker

Everyone watched as All Might jumped towards the villain and Izuku put his hands into the air. That's when Aizawa noticed what he was doing, "...This is Midoriay's ultimate move" everyone turned to him. "Yeah he told me it gathers energy around him into a ball that affects evil"

"That is correct, but the energy he draws must be voluntary. This is where we come in, everyone raise your hands into the air, Izuku will draw the energy within you" Dende explained putting up his hands into the air.

"All we have to do is put up our hands?" Mina did just that and as soon as she did the energy within her began to appear as blue colored particles. "Wow so pretty"

Everyone quickly followed suit and their energy began to flow outside of the bunker and towards Izuku.

"If that's the case, why don't I make some quick phone calls" Nezu said, grabbing his phone and calling multiple numbers at the same time.

With Izuku

"Come on, come on I need more energy" he said as the spirit bomb grew bigger. "T-This energy it's from my class, Mina, Kirishima, Shoto...everyone in the class" Izuku smiled. "Thank you everyone but I still need more energy"

That's when Izuku felt the spirit bomb grow massively, looking up he saw the bomb was about 50x its original size. "Wow...this is Himari's energy, Bakugo's and Uraraka's too but where is this all coming from? Wait…this is the Ki from every hero in Japan! Nezu must have made some phone calls then"

That's when All Might could be seen on the edge of the crater beaten, "All Might!"

"Well well well what do we have here" Vent said, stomping on All Might's back. "...What is this power! How did you get this power?"

"Damn it even with All Might's power back he still didn't stand a chance!" Izuku said, gritting his teeth.

"You were planning to use that on me weren't you?" said Vent.

"Y-Yes…" Izuku admitted.

"Too bad you won't get to use it" Vent fired off multiple ki blasts at Izuku. Izuku could do nothing but take the attacks.

King Kai's Planet

Goku and Vegeta watched as Izuku was being pummeled by the blasts, "He's not doing too good," said Goku.

"No he isn't, at this rate he's going to end up dead again" Vegeta said crossing his arms.

"Then why don't you two idiots do something about it then?" Master Roshi said, walking out of the house. "He needs energy for the spirit bomb doesn't he, so why don't we send him some of ours?"

The two saiyans looked at each other, "Well duh! Why didn't we think of that" Goku said facepalming. "Alright let's do this Vegeta, just like when we fought against Buu" he said putting up his hands.

"Fine, only because he's a fellow saiyan" Vegeta reluctantly put up his hand.

"Good" Master Roshi smiled. "Best of luck Izuku" The trio's Ki began to flow towards Izuku.

With Izuku

Izuku could no longer feel anything as the blasts kept coming, 'I-I can't break focus, if I do I'll lose the spirit bomb!'

Vent smiled as he fired blast after blast at Izuku, that is until All Might reached out and grabbed his leg. "I would appreciate it if you don't harm my students anymore" All Might said smiling.

"Well if you put it that way…" jumping off of All Might, Vent kicking him hard sending him flying towards some rocks. "You stay right there, I'll be right back" he said flying towards All Might.

"Come on! I need more energy! Someone, anyone please give me your energy" Izuku said, crying out. That's when he felt something approaching. "W-What is that? Three Ki sources are approaching and they are strong...wait I felt these before" Izuku smiled. "Thank you Goku, Vegeta, and you too Master Roshi" as there Ki joined the spirit bomb grew exponentially. Everyone around Japan could see the giant blue ball of energy. Izuku slowly began to fly up pushing the spirit bomb along with him.

Uraraka, Himari, and Bakugo watched as the giant ball began to rise, "It's done" Uraraka said, falling to one knee as she had given up most of her Ki.

"Now Deku do it, finish this once and for all" Bakugo yelled as he too gave everything for the spirit bomb.

All Might was getting repeatedly kicked by Vent, "Did you honestly believe that you could have defeated me?"

All Might smiled, "I wasn't trying too. I was just the distraction"

"What!" Turning around Vent saw the giant spirit bomb flying towards the sky, and Izuku with his hands up.

"All Might! Get out of the way!" Izuku yelled.

All Might got up but before he could leave Vent broke his leg, "Y-You're not going anywhere!"

All Might screamed in pain, "D-Do it! Throw it!"

"I can't get, you'll get caught up in the blast!" Izuku yelled back.

"What are you waiting for, Midoriya! Throw it! NOW!" All Might said grunting in pain.

'Damn it he needs to get out of the way!'

"SMASH!" Izuku looked down to see Mirio appear from under the ground and punch Vent away from All Might.

"Midoriya! Do it! I'll get him out of here" Mirio smiled as he grabbed All Might and ran at top speed away from the battle field.

"Awesome thanks Mirio!"

As he was being cared away All Might looked back to see Izuku. "Do it kid"

"This is it Vent! A final gift from every hero in Japan! Have it!" Izuku threw his hands forward, as he did the giant spirit bomb fell towards Vent.

It seemed as if the sun itself fell towards the ground, Vent watched as the bomb got closer and closer. The bomb itself broke the ground as it rocketed towards Vent. Putting out his hands Vent tried to push back the blast but instead of stopping it, it pushed him back breaking the ground underneath him. "This won't be enough to kill me! HAAAAAA!" Vent yelled, pushing hard against the bomb.

After a few seconds digging his feet into the ground, Vent managed to stop the blast, "No way! HAAAAAAAA! Izuku yelled out pushing harder but he has no more energy.

The two were now in a deadlock, neither side winning but also neither lossing. Back and forth the bomb went out neither could make that final push, Mirio managed to find Uraraka's group putting All Might down they looked on as the two pushed against the blast.

"He needs more energy," Uraraka said looking at the giant blue sphere.

"We already gave him everything we had!" Bakugo said, amazed at the show that was happening in front of him.

"Not everything" Everyone looked at All Might. "The remainder of my power, I'll give it to him"

"But sir, in your condition, if you give up all your energy you can die" Himari explained.

"I am well aware...but that doesn't change what I have to do" pointing his hand in the direction of Izuku, All Might let everything out. His Ki was like a flame in the wind. "The very last bit of One for All inside me...I give to you Midoriya. My debt has been paid" transforming into his skinny form All Might fell unconscious.

Izuku was starting to lose ground. He was much more damaged than Vent was, blood dripped from his open wounds, "Damn come on hold on body! Don't give up on me!" he yelled out as Vent pushed the bomb back at Izuku.

"Hahahaha! Nice try saiyan but your attack is now mine!" Vent said, taking step after step forward.

"No it can't end like this!" Izuku closed his eyes, just as he did All Might's Ki engulfed his body. It looked like Izuku was on fire, "Woah whose power is this? It feels like All Might! With this we are now even All Might thank you!"

Transforming into super saiyan Izuku stopped Vent dead, "Well it's been fun Vent but it's time for you die. I won't lie after everything I still had fun in this fight, you are arguably the toughest opponent I've ever faced. So if you ever get reincarnated as a good guy come and find me, we'll have a rematch"

Vent smiled as he pushed as hard trying to make the spirit bomb move to no success, "You saiyan, no Izuku Midoriya, our paths will cross again I promise you that. You will come to realize two things, one is that strength is the only thing that matters in this universe. And two, is that we all work for someone…" Vent put down his hands in the act of giving up.

"Deku! Izuku! Midoriya! DO IT!" his friends and family yelled out.

"Goodbye Vent. HAAAAAAAAAAA!" With one final yell Izuku gave the spirit bomb one final push, launching it towards Vent. His body disintegrating as the blast overcame him, the blast itself broke the ground leaving behind a trail of destruction. Making sure it wouldn't hit the earth Izuku redirected the bomb up and towards the sky.

Anyone who was outside across Japan could see the giant spirit bomb fly into the sky, getting smaller and smaller as it went higher until it reached outside of Earth's orbit. Seeing that it was a safe distance Izuku closed both hands causing the spirit bomb to explode.

Blue energy particles began to fall all over Japan, Izuku had just beaten Vent. Izuku floated in the air as he breathed heavily, "I-It's over" not having the stamina to keep super saiyan going. Izuku reverted back to his base form and fell towards the ground very reminiscent of when he fought E23.

Closing his eyes Izuku felt the biggest weight on his shoulders disappear, "Deku!" opening his eyes he saw the pink glow of someone aura heading his way.

"U-Uraraka?"

"Deku!" she yelled, trying to catch him before he hit the ground.

As he was about to hit the ground Uraraka slid on the ground scraping her knees but she didn't care she made it just in time to catch him. Well more crash into him, as they rolled to a stop Uraraka laid on top of Izuku.

"H-Hey Uraraka, are you alright?" he smiled as bruises and cuts covered his face.

"Hey Deku, yeah I'm alright a few cuts but I'll live" she said, starting to cry.

"That's good, hey I did it, I beat Vent," he said.

"Y-Yeah you did, I'm so proud of you Deku" she said hugging him tight.

"Hey! Is he alright?" asked a voice, looking towards the sky they saw Bakugo and Himari flying towards them. Behind then running was All Might being carried by Mirio.

Uraraka wiped away the tears, "Y-Yeah he's alright!" she yelled out.

"Hey Uraraka" she turned to him. "I love you"

Uraraka felt her face turn red, "I love you too Deku" she leaned in kissing his lips.

"Are you two done flirting?" Bakugo said landing beside them.

"Oh quiet you, let them have their moment" Himari said, hitting Bakugo's side. "Good work Izuku," she said smiling.

Mirio and All Might arrived, "Midoriya my boy how are you holding up?"

"Pretty good all things considered but if you guys don't mind I would like to go back to school" he said getting up with the help of Uraraka.

"Alright then let's go, Dende is at the school so maybe he can heal you up" All Might said.

Bunker

"Is-Is it over?" Iida asked.

"Yes, it's over," said Dende. What followed was a few seconds of silence, then followed by the whole class erupting in cheer. High Fives and hugs for everyone even Aizawa got involved in it all.

"I knew Midori could do it!" Mina said on the verge of tears.

"Never had a doubt," Todoroki said.

"I should go over to them so I can heal them up," Dende said to Nezu.

"Yes please go" before he could Dende was hit in the face by a large pellet that exploded on contact releasing a gas knocking him out.

"Who did that!" Aizawa looked around to find Momo with Eri in her arms, both of them wearing gas masks. "Yaoyorozu what's the meaning of this!?" everyone stood stunned and what she just did.

"I'm sorry" with a heavy heart she created two gas canisters, pulling the pins on them both she threw them towards her class.

One by one her classmates fell victim to the gas, the last one standing was Todoroki, "M-Momo why?" he said, stumbling towards her.

"I'm sorry Todoroki, I really am" Todoroki tried to create a ice coffin to stop her but it fell short. "Tell Midoriya and Uraraka I'll be in contact soon and I'm sorry" and with that Momo made her escape as Todoroki fell unconscious from the gas.

A few minutes later

Everyone landed near the dorms, "Well we are back, no more evil aliens. We can go back to being normal for a change" Uraraka said walking into the dorms. "Hey where's everyone?"

Izuku's eyes went wide, "Something's wrong, are they still all in the bunker?"

"Yeah they should be, why?" asked Bakugo

Walking down to the bunker they stopped when they saw everyone knocked out, "What the hell!?" as Bakugo went to check on everyone he saw they were just asleep. "Good they're still alive, just sleeping"

"What happened here?" asked Uraraka.

Both Himari and Izuku sniffed the air, "Gas, someone let out anaesthetic gas" Himari said looking around.

"Wait guys where's the tall girl?" said Bakugo.

"Oh no Eri is missing as well" Himari said, "Oh no the gemstone!"

"Momo must have created a knock out gas. I didn't even know she could do that, but why?" Uraraka was puzzled as to why she would do that.

"Doesn't matter right now we need to find them…" Izuku stopped mid sentence as his eyes rolled back. Uraraka felt his body fall limp as she struggled to keep him up.

"Deku!" looking down at her hand she noticed blood covered it. "Oh no, Deku come on hold on. Bakugo go call Recovery Girl!" Bakugo nodded and took off at top speed.

With Momo and Eri

"Aunt Momo, where are we going?" Eri asked as she was getting pulled down the street by Momo.

Stopping in front of an old run down building Momo took a deep breath, "Let's go" as they walked in the dark building Eri started to become more and more nervous.

Stopping in a big open room Momo stepped up, "We are here"

"Good, very good" a voice was heard through the darkness. Suddenly a light shined on a man sitting in the middle of the room. "It was half expecting you not to show up" turning around it was revealed to be Shigaraki. "Hello Eri"

Eri hid behind Momo's leg, "Oh you don't have to be afraid of me, I'm not going to hurt you" he smiled. "It's him you need to be afraid of" he said pointing to the shadows.

"Hello Eri" she recognized the voice before it was revealed who it was. Immediately she began to tear up and tremble. "It's been a while" from the shadow out walked Chisaki 'Overhaul'

AN: His victory is short-lived, now Izuku has to find Eri but can he do it in his current condition? Dun Dun Dun! The League of Villains and the Yakuza together? What does this mean for Eri and why is Momo working for them!?
