After Shigaraki body recovered from his fight against stars and stripes All for one completely takes it over. He is not able to access her quirk after stealing it. But he was able to stop her from destroying all of his other quirks. The vestige of Stars and Stripes is locked away inside of All for one quirk just like Shigaraki consciousness.

Afo first plan backfires (take star and stripes quirk and become unstoppable)

Now that he's taken full control over Tomura's body he can put his next plan into action stealing One For All and killing Izuku Midoriya But to do that he's going to need someone's quirk.

Meanwhile at the police station where kai chisaki is being held two 2nd generation nomus attacks the station a third one with wings takes overhaul and flys away so that Afo can steal his quirk.

Three weeks later Afo can fully control the overhaul quirk. Now it is time to try an take one for all again before killing Izuku.

UA high school

Izuku Midoriya is training for the inevitable fight against Afo. Everyone heard about what happened to chisaki izuku can use up to 70% of One for all. He's been training for the past ten hours.

"Young Midoriya that's enough training for today" All Might said concerned about his successor. "No not yet I need to be able to use 100% of One for all." Izuku said while he's flying kicking the air practicing combat in the sky. "all for one is out there getting stronger I have to be able to stop him."

"Lesson young Midoriya it's good to train but if you don't get any rest then you're just torturing yourself." I'm fine I can go for another two izuku never got to finish that sentence as he clasped on the ground.

All might had to carry Izuku back to his dorm on his back. "He was out training all day wasn't he?" Uraraka asked when she sees all might carrying A unconscious Izuku. "Yep he needs to take it easy on his training we don't know when Afo will strike so young Midoriya can't be worn out before the fight starts." All might said to Uraraka while putting Izuku in his bed.

The next day

All for one is looking at U.A from the distance with three 3rd generation nomu's

Ready for his attack.

Back at U.A Izuku decided to take All might's advice. He was sitting on the couch in the lounge relaxing writing in his notebook. Trying to Think of some new stuff he can do with all his quirks. That's when danger sense went off in his head.

"He's here" Izuku said with a serious tone.

"Who?" Class 1A said simultaneous "All for one" Izuku said as he powers up One for all and runs out the dorms only to see all for one in shigaraki body hovering over the school.

"Can you save them?" All for one said before he starts to decay the school building. Leaving no survivors "seriously did they really think that security upgrades were going to stop me." All for one said mocking a dead principle Nezu.

"Why?" Izuku asked as he couldn't believe all those people who took refuge here are now gone.

"I needed to get rid of all the teachers and pro heroes I know I could take them on but I don't want the extra trouble" all for one said looking down at Izuku who is trembling with sadness and rage 'All might, mom, koda, eri they are all gone.'

Izuku thought to himself.

"It looks like your friends are coming over here." all for one said as he sees Class 1A rush over. hearing this Izuku turns his head to see all his classmates coming over to him Ready to fight.

"I had expected this which is why I brought some friends to keep them busy" with that All for one uses his warping quirk to summon three 3rd generation nomu.

"Have fun cause as much chaos as possible but leave Izuku to me" all for one said to his nomus who let out a monstrous sound. Izuku wasted no time as he activated one for all while class 1A prepared to fight off 3 nomu.

Izuku uses black whip to grab hold of All for one and pulls him "SMASH" Izuku yells out as he punches all for one in the face at 38% all for one who wasn't expecting that stumbles back a bit.

All for one and Izuku then begin a intense battle.

class 1A is able to hold off the nomus with a little bit of teamwork. mineta uses his sticky balls to trap one while todoroki covers it with a ice glacier. "DIE" Bakugou yells out while he's pulling the pin out of his gauntlet. Knowing it can regenerate Todoroki freeze it again Bakugou then fires off a bunch of explosions making sure it can't regenerate. Momo creates more gauntlets for bakugou to use on the rest of the nomus.

Meanwhile All for one and Izuku continue their fight with Afo having the advantage because of experience. While they are fighting Afo manages to knock Izuku out of the sky landing on his back Afo sees this as a opportunity he goes up to him and puts his hand on his head attempting to steal One for all. "Last time I couldn't take one for all because shigaraki body wasn't complete now there's nothing stopping me from taking it." All for one said as red lightning starts coming out of his hand. Izuku along with the vestiges of the past ofa users ended up in the vestige of All for one. They all looked around and noticed a lot of balls that have different colors just floating around. "Theses must be all the quirks he stolen" Izuku summaries out loud . "They are" A voice called out grabbing their attention all the previous ofa users turned around to see a woman chained up and bound to a wall Izuku quickly recognized her as the number one hero in America Stars and Stripes.

"Get used to your new home" A voice said putting them on alert.

All for one then appears in his own vestige world.

"I can appear in this place when ever I want it was how I was able to stop her"All For One said pointing at stares and stripes.

"as long as she is chained up she can't use her quirk and nether can I unfortunately."

All of the one for all users stand ready for a fight. But All for one just laugh

"I killed all of you in the real world what makes you think you can beat me in mine." Izuku wasting no time charges at all for one "SMASH" Izuku yells out as he punches all for one in the stomach at 20% ofa. Afo wasn't even fazed by the hit

"Physical attacks can't hurt him." Stars and Stripes says

"how do we beat someone who can't take damage?"

Nana said while Izuku comes up with an idea. He Silently communicated his plan to the other users. Izuku jumped in the air behind All for one making him turn around. 'Step one complete.' Izuku thought to himself. "Delaware Smash"Izuku yells out as he does a finger flick at a random wall then another. Then another not even aiming at anything specific All for one is very confused and asked "What are you doing"

'Second part complete' Izuku thought

As he answers Afo question "nothing I just needed to create a distraction." Hearing this Afo quickly turned around and was met with a sight he didn't want to see.

Standing in front of him was Stars and Stripes no longer chained up and is able to use her quirk.

"I might not be able to defeat you in here but she can" Stars and Stripes then activated her quirk to destroy All For One's quirks. hundreds of floating lights started to Disappear Afo seeing his quirks being destroyed try's to hold onto the quirk he got from overhaul it will be how he plans on killing Izuku. 'I need to send all of them out of here.' Afo thought to himself mad that he won't be able to take One for all but at least he will still have some quirks left over.

All for one opens up a portal which will lead them back to Izuku's consciousness. they all started to get sucked into it like a vacuum. unfortunately the sucking causes the quirk that Afo was protecting to also start floating away from him. As they are all being sucked into the portal Stars and Stripes sees All For One trying to hang onto a quirk, thinking that it's important she grabs it as she is also being sucked into the portal. So that Afo can't have it.

Back in reality only 30 seconds have past when All for one put his hand on Izuku head to try in steal is quirk. As soon as Izuku comes back to his consciousness they both get blasted away from each other. Izuku's classmates and friends comes over to help out. After they had finished off the nomus. All for one seeing that he might be in trouble uses his warp quirk to summons the league of villains.

"This is going to be a tough battle guys. If you want to back out do it now." Izuku said to which no one objected. They was going to see it till the end.

"Let's kill these Bastards." Bakugou said grinning. And with that the battle begins.

Time skip

Izuku Midroriya is the only one from his class still standing. He couldn't save a single classmate. However he didn't have time to mourn because All for one is coming at him. "Your going to die just like the others." All For One said, lifting Izuku up in the air. He than threw Izuku into a pile of rubble. Trying to break him down an order to steal One For All.

Supreme Kai World

"Sir Majin Buu has gone into hibernation." A pink skinned man said. He had long white hair, and a broad face

"That's good Kibito." A small purple man said. He had a white Mohawk.

"Tell me Why do we take care of him?" A old man had asked. He was also purple with white hair.

"Because great ancestor he is technically a Supreme Kai."

"That's because he absorbed the real one. I'm glad he's asleep. He keeps on turning all our food into sweets. I don't even like chocolate that much."

"Sir you have to see what's happening on Earth right now." Kibito said making the other two look at the crystal ball.

"Wow that kid is on the verge of death. Goku used to protect Earth. But he's been dead for centuries now." Supreme Kai said as he watched Izuku get blasted in a building.

"That boy clearly not strong enough to beat that man. Kibito come with me."

"Where are you going?" Supreme Kai asked

"You just keep watching the crystal ball."

Kibito and old Kai are standing next to Buu who is asleep.

"Kibito teleport us in front of that boy."

Back With Izuku

Izuku was just blasted through a building with a air cannon.

Izuku was laying on his back and a building. He was in what used to be a office. Now it's just a room with a bookshelf, a hole in the wall, a desk slice in the middle with Izuku laying in between both parts.

"I'm to weak." Izuku said with sadness in his voice.

"You damn right you are." Old Kai said making Izuku lift his head up to see who was talking.

"W Who are you?" Izuku asked

"My name is not important. However I'd like you to meet Majin Buu." Old Kai said pointing at Buu who is sleeping.

"Huh Buu?"

"Im going to seal Buu inside of you. You will gain his strength and magic properties."

"Wait, why?"

"We don't have time for questions. Just search through his memories to find out What he can do " Old Kai says as he starts his spell.

Majin Buu started glowing then he disappeared. Izuku felt a wave of power course through him.

"Well it's time for us to go Kibito." And with that Old Kai vanished. But not before kibito heals Izuku.

Izuku walked towards the hole in the wall. His green hair covering his eyes. Izuku looked up at All For One with red eyes. A pink aura started surrounding him. He closed his eyes and started accessing Buu's memories

"Wow I don't need that much power." Izuku said after going through Buu's memories Izuku decided to fire off a Pink Ki blast at All For One/Shigaraki. He destroyed him along with what was left of U.A.

Izuku looked around at the scene. What was once a giant school is just a bunch of dirt and rubble. Now that the fight was actually over everything started to sink in.

"No one survived." Izuku said shaking. His pink aura and red eyes came back. The area started shaking.

"I COULDN'T SAVE ANYONE!!" Izuku screamed out loud. With him yelling and his immense power he was able to tear a hole opening up multiple portals. Looking through one he sees a alley.

"Hmm must be a teleporting ability that Buu has." After saying that he goes through the portal. Little did he know that portal lead to another universe.

Supreme Kai world

"you sealed Buu inside of that boy." Supreme Kai said to old Kai.

"Yep he's sealed away forever inside that boy. We don't need to take care of him anymore." Old Kai said

Supreme Kai watched Izuku beat All For One. Then he saw Izuku open up a portal. "Oh no, great ancestor you have to see this. The boy you sealed Buu in just entered a different universe."

"What?" Kibito said

All three of them looking at the crystal ball.

"We have to get him back." Shin said

"There's hundreds of universes out there. And your not strong enough to create a portal to bring him back."

(This is not based off of Super)

A/N it is 3am I'm not reading this over to see if I missed spelled anything. I'm going to explain Izuku's powers and quirks in the next part. Had to give him some power ups or else he'll be cannon fodder in that universe. That's why Buu's sealed inside him
