I Dont own My Hero Academia or Dragon Ball. Kohei Horikoshi and Akira Toriyama own them respectively.

BOLD= All For One's voice

The Yaoyorozu Family- This family of 3 is the richest family in the world as they have gotten most of their money from stock markets and any investment they made has multiply in quality and eventually worked on real estate and construction which made them billionaires. No one knows how they won so much money as none of their quirks deal with the future and so they kept the money and its said they bribe heroes to arrest "criminals", who just so happen to be the familiy's competitors and they have Hero Agencies on their payroll. The family is practically untouchable as the mansion is full of hero bodyguards with the palace having at least a thousand rooms. The family is Jack, The Father, Jill, The Mother, and Momo, The Heiress.

With the gear of All For One, Izuku has landed in the middle of the Yaoyorozu front courtyard and it was massive! "Whoa! This mansion is like the Erdogan Grand Palace in Turkey!" He then closes his mouth as he knows that its illegal to be in the Mansion and he doesn't have his voice filter on. He starts working on the filter in the All For One helmet. "Lets see the old man's voice was deep so somewhere around this. Yep, this is definitely his voice. Like he's cosplaying Darth Vader." With this, he can impersonate the deceased super villain but he needs to get the quirk in the mansion as from All for one's memories, it is definitely important but odd considering where it is.

(Flashback)

6 years ago

"Im Shinbun Kisha(1) reporting here at Yaoyorozu Mansion as a meteorite has crash right on there lawn and now they are claiming it as there property, im right here with Jack Yaoyorozu, Yaoyorozu-san could you explain why you want to keep this meteor as shouldn't the government be allowed to study it?"

The black haired middle aged man repiles " This meteor has landed on my property and I can claim it as my own. Don't worry I will donate a large piece to our fine government but the majority will be kept in my estate." With that the man leaves the reporter and has the meteor lifted thanks to a crane.

"Well there you have it, Yaoyorozu-san has said his story and we will get an answer from the Diet real soon, back to you at the office."

A non-injured All For One looks at the news looking at the meteor and notices a strong aura around the outer space rock. Something is inside it and is powerful but he cant go after it yet as he needs to deal with Nana Shimura's successer of One For All first. Plus he already knows what the Diet will say without waiting for the news, the entire government is on the family's payroll that people are calling them: The Unoffically Imperial Family.

However, he would be injured during his fight with All Might and focus on healing but his investigation did say the meteor is in the basement of the mansion.

(Present Day)

With that, Izuku snaps out of the flashback and decides how to begin the assault, with a roar he shouts "KINETIC BOOSTER!" This quirk increases his kinetic energy and then raises his hand and with another shout "EXTREME AIR CANNON" He sends a large gust of wind that destroys the East Wing of the mansion. Thanks to the blueprints and All For One's memories, he knows the hatch to the basement is in this wing. He also sees a few hero bodyguards and Jill Yaoyorozu hit by the blast and injured but he doesn't care about them and focuses on looking for the hatch.

"Hey you villain!" Izuku hears a yell, then moves away as a wind blast almost hit him. He looks at the direction the blast came from and sees a unharmed highschool student with a brown armor-like outfit with the signature hat of the hero school: Shiketsu High. "I am the Wind Hero: Gale Force! Prepare villain, as I won't let you hurt the this family!" The teen yells with passion as he creates a whirlwind and hits Izuku with full force.

BOOM!

The wind sends the disguised villain into the West wing and crashing into walls. "OW, That hurt, a little." He jokes as he gets up and remove the rubble from his suit. "AAAAHHHHH!" Izuku hears a hypersonic yell and causes him to go on his knees in pain. He sees the number 10 hero, Gang Orca and the whale hero charges at the downed villain but he creates spikes from his arms and stabs him. "Its a good thing we are not near any water, otherwise I be endangered." Izuku says as he know Gang Orca is better in underwater combat due to his whale physiology. However, the whale hero jumps straight at Izuku and opens his toothed mouth and is about to bite him.

" I will defeat you All For One!" Shouts Gang Orca however Izuku uses another quirk,"Density Control" once the whale hero bites the disguised villain's shoulder, it feels like he is trying to eat the toughest metal and his teeth even breaks. As his mouth is bleeding and without warning, Izuku punches Gang Orca "Suffer whale boy, 24,000 POUND PUNCH!" It was like the green skinned teen's arm was harden and the punch knocks out the number 10 hero. He goes invisible as he hears footsteps and sees Gale Force.

"Master!" The wind user runs to his mentor to check on him but while he is checking on him, he gets neck chop by the invisible villain and knock unconscious. Izuku then reappears and decides to steal their quirks. He goes back the destroyed east wing and searches for the hatch. He also sees Mrs. Yaoyorozu and decides to heal her injuries but steals her quirk: Teleportation- She can teleport inanimate objects.

(Meanwhile at Sir Nighteye''s Hero Agency)

Within the agency, Sir Nighteye and Mirio Togata are talking to each other in his office. Both are talking about the new One for All user, Kouta Izumi.

"Sir Nighteye, I don't care I won't get One for All. Im happy being just who am, a hero my own way." Mirio says with a smile, While Nighteye is more annoyed then happy.

"Togata, a child is suppose to be the next symbol of peace. This is a joke I would never laugh at. We need to convince All Might that you are the next #1 hero and get Izumi to give you the quirk." As they are talking, the former sidekick of All Might's phone rings and he answers it. "Hello?"

"Nighteye its Jack, someone is attacking my house and I think my wife is injured!" The caller is his old friend Jack Yaoyorozu and instead of the calm voice he's known for years, its a voice of despair.

"Listen Jack, I will go to your house. Tell me where are you right now!" Nighteye yells as he cares for his friend, he gives a hand signal to Mirio, telling him to get his hero uniform ready with Mirio running to his locker.

"Im at my basement and I think they found the hatch. Please old friend, Im begging you, hel-" The phone call ends and Nighteye gets his suit while Mirio enters with his Lemillion outfit.

Nighteye then gives Mirio a hard glare. "Mirio, go get the intern maybe her acid quirk could help this situation."

"You got it boss." Mirio then walks out of the office and sees the new intern "Ah! Greetings Ashido-san we have a job for you."

"Seriously? That's awesome! Im going on my first real hero mission." The pink skinned high schooler, Mina Ashido says with excitement and cheer.

(The Yaoyorozu Basement)

Jack Yaoyorozu was a man that like to be in control, weather it was choosing what school his daughter goes to, what dress his wife wears, how to spend his money, or a person's fate if they tried stealing from him. Either way, he loved control but when something doesn't go in his favor, he starts freaking out as this situation is an example. When a giant explosion hit his mansion, he was only concerned with himself and the meteor so he barricade the basement and hoped the heroes would deal with the intruders. His daughter was at U.A and he saw his wife injured from the blast but he cared for neither as the meteor was his only prescious. When he sees the mask of All for One enter the basement and looks at the billionaire, it breaks Jack with sheer despair.

"P-please A-all for One-sama, please spare me. I DON'T WANT TO DIE! UWAAHHH!" He starts crying and begging and Izuku was amazed with this man's cowardice. He just entered the basement and immediately this billionaire is groveling on the floor. 'At least when I was young, I was scared of Kacchan but I would stand up to him.' Izuku thinks to himself but then decides to talk to him as All for One

"Answer this question and I may let you live. Why did you keep the meteor instead of giving it to the government all those years?"

"The aura that came from the meteor was enticing and I wanted it for myself. Sometimes if Im having a slow day I would stay in the basement for hours and just let the warmness of the rock just surround me." The billionaire answers while finding a way to distract the villain and attack him with his quirk: Obsidian- Can transform his entire body into obsidian metal.

"Then show me the rock and I'll let you live." Says Izuku with intent to injure him if he tries a trick.

"Of course, follow me" Jack says as he shows him to a lock room as he unlocks it with his key. With that the disguised villain sees the 10 foot meteor and notices the energy its giving and there is something inside the meteor, so he gets closer with Jack behind him and he uses his quirk with his skin turning deep black and charges at All for One.

"Strength Enhancer!" His physical strength increases and then "Diamond Body!" With this, his body is incase in diamonds. He blocks the first punch and begins punching him but Jack withstands the punch and punches back. They begin punching each other and even though Obsidian is sharper then diamond, thanks to the strength enhancer he is breaking his arms. "Muscle Augmentation!" It amplify his muscles and it ends with Izuku punching Jack in the chest and breaking his obsidian body. With that he falls to the ground unconscious. He than summon the spikes and absorbs the Obsidian quirk.

"Hm, so this is how your daughter has the creation quirk. Your metal quirk and your wife's teleportation can act as a summon thus creating a creation quirk." Izuku begins mumbling as he spits out some blood but refocuses on the situation. He gets closer to the meteor and sees something quite interesting.

There is a body in the meteor. The male seems to be human, only with a monkey tail on him and around 8 ft with huge muscles. Izuku puts his hand of the ice and reads the mind of the man. "He is dead but I can see the memories of even the decease thanks to the quirk Memory View. I'll view this person's life as Im sure this could be an alien and viewing his memories may give me a view of his powers. Lets see, his name is...

Broly."
