{Time Skip...}

Damian is seen leaving Nezu's office and walks down the hallway to hear the school bell ring.

Damian: "Just in time."

Damian makes his way to the cafeteria and takes a seat as Midoriya, Iida and Uraraka sat next to him.

Izuku: Hello Abbott, how are you?

Damian: Good.

Izuku: So, since school is gonna finish in a minute after we have a quick snack, do you wanna go to that new store down the road?

Damian: Sure.

The bell rings and Damian and Midoriya walk outside but Midoriya turns right, and Damian finds out the both Of Them are going to the dormitory.

Damian: Why are we coming here?

Izuku: I have a present for you.

Damian: Ok.

Izuku and Damian walk into the dormitory and Izuku walks into his room then walks out with a suitcase.

Damian: What's in the case?

Izuku: Open it!

Damian: Alright!

Damian opens the suitcase and finds a pretty beaten and worn out suit with a backpack full of survival gear but they are Red. (Just the suit and it's folded up.)

Damian sits in awe and says. "Thanks, Midoriya but why give me a suit?"

Midoriya: Because from what I heard your great in hand-to-hand combat and you don't have a suit! *Continues to ramble*

Damian: Izuku.

Izuku: *Still rambling*

Damian: *Sighs* Stop nerding out!

Midoriya: *Chuckles while sighing* I did it again...

Damian: Yeah, anyway I'm gonna wear it!

Izuku: Of course!

Damian walks into Izuku's room and gets dressed into the suit and Damian walks out.

Izuku: That looks good on you!

Damian: Yeah, it's pretty cool!! Ok we can head to that new shop now.

Damian says as Shoto and Katsuki pop in out of nowhere.

Katsuki: THEN WHAT ARE WE WAITING FOR, LETS GO YOU EXTRAS!!

Shoto: Let's go calmly, nice suit Abbott.

Katsuki: WHY!!? THEY APPARENTLY HAVE THE MOST SPICY FOOD!! AND I WANT A REMATCH WITH THAT QUIRKLESS EXTRA!!

Damian: Challenge accepted Kacchan!

Shoto and Izuku sweat drop. Damian, Bakugo, Todoroki and Midoriya keep walking, yelling, and telling jokes but until everyone heard a massive explosion.

Izuku: Damian stay here!!!

Damian: What, why?!

They Then use their quirks to get to the explosion. Damian then puts on his hood and runs as fast as he can towards the explosion.

Damian: I need to help!

Damian keeps running until he see's a hero that is dead on the ground but turns into ash.

Damian: 'Ash?! Wait, no, no, no, no it's Shigaraki!!!'

Damian keeps running and he see's Bakugo being thrown out of a destroyed building across the street from Damian. Damian runs over to Bakugo and sees him turn to ash.

Damian: K-katsuki?!

Damian runs over to the building Bakugo was thrown out from and see's Shoto crawling towards him. Damian then notices his legs are decaying and runs up to Shoto.

Shoto: DAMIAN!!!

Shoto then uses his ice and shields Damian from Some falling debris. Then he uses his ice to get Damian out of the building but before Shoto went out of site, the ice stopped and he turned too ash. Damian looks around for heroes but can't see any. Damian then hears another loud explosion and he turns to see Midoriya is using float and he is fighting Shigaraki but Shigaraki managed to touch Midoriya as he tried to strike him with decay and he fell from the sky and lands onto a car, Damian then runs over to Midoriya.

Damian: Midoriya!

Izuku: Quick, take my quirk now!!

Damian: H-huh?!

Izuku: Take my quirk! Just eat a strand of my hair... *Coughs*

Damian then see's Midoriya slowly turning to ash so Damian eats a strand of Izuku's hair.

Damian: Midoriya, everything is gonna be ok! Just hold on!

Damian says as he looks around frantically for a medical hero.

Izuku: Damian... It's ok.....

Damian picks him up in his arms.

Damian: No, it's not ok! I can't watch you die!!!

Izuku: *Smiles* You will make a great hero...

Izuku turned to ash while smiling happily, Damian fell to his knees in defeat and sorrow as Izuku's remains blows away in the wind.

Damian: *Clenching Midoriya's dust* Thank you Midoriya... For everything...

Then Damian starts hearing sirens.

Damian: H-huh?!!

Damian see's civilians running around in fear and he looks up and see's a nuke dropping from the sky.

Damian: Oh my god...

Damian felt a presence in his body and all of a sudden he flew into the air.

Damian: Whoa! What's happening?!

Damian kept floating into the air and stopped. Damian see's the nuke land and the bomb exploded the entire Japan. After an hour,Damian felt the presence leave his body as he floated back down. Damian looks around but see's the city in chaos as he floats down.

Damian: No... NO!!!

Damian lands and runs around for a bit but only see corpses everywhere. Damian sat down on the cracked road and lays against the light post. Damian falls asleep but wakes up instantly to find he is in some kind of shadow looking house that has 9 chairs turned around.

Damian: Where am I?

???: So, you're the Tenth?

Damian looks forward to see a white-haired man. 

Damian and the white-haired man reach out to each other to touch hands as Damian Sees's his green eyes then Damian woke up panting heavily as he looks around frantically and then looks at his arm as he sees red like veins of energy on it as it slowly disappears.

Damian: "W-who was that?"

Damian stood up and looked around for a little longer and sees the ground a little pulverized ever since he woke up from the "dream".

Damian: "So Midoriya gave me his quirks but I haven't unlocked Them yet except for me Floating... I guess I'll try Floating again?"

Damian stands up and looks up. Damian activates Float and starts flying at high speed then he turns around as he circles the spot he was originally standing at as he touches back down.

Damian: "Awesome... I guess I need to try and unlock my other quirks since I did see Midoriya use more than one... While that's happening, I'll keep looking for any survivors."

{Time Skip...}

Damian: Nothing but death...

Damian lands on top of a building and see's a little safe house that's untouched, Damian runs inside with a huge smile waiting to see a person but see's no one as his face goes back to one of a hollow frown.

Damian: "Damn..."

Damian then see's a bed that's also untouched. Damian lays on the bed and dozed off. Damian woke up in the same place but this time he was outside the house so he walks inside. Damian then see's nine people standing and talking. Damian looked at his body and it was a Red-Blue aura And then the nine people notice Damian and walk towards him.

???2: Is it him?

???3: Of course it is!

???8: It's young Abbott!?

Izuku: Wow nice aura Damian!!!

???7: Hah told you he would unlock my quirk first!

???6: Aww man I thought it was gonna be Blackwhip...

White Haired Man: Quiet you idiots!!!!

???1: I thought he would be older?

???3: He's the youngest One For All user!?

Damian: Who are you and where am I?

Yoichi: Oh sorry where's our manners, I'm Yoichi Shigaraki.

Damian: "No way!?"

Second user: I can't remember mine...

Third user: Same...

Hikage: I'm Hikage Shinomori.

Daigoro: And I'm Daigoro Banjo!

Nana: I'm Nana Shimura and you unlocked my quirk first!

Damian: It's a beautiful quirk!!!

Nana: Why thank you!

Toshinori: I am all might!! *Poses* but I'm actually Toshinori Yagi!

Izuku: Well, I don't need to explain anything right Damian?

Damian walks up to Izuku and hugs him.

Damian: I thought you were gone forever!!

Izuku: I'm sorry.

Damian: Don't be and why am I here?

Yoichi: We brought you here but only in your sleep and we came to tell you when you wake up, you're gonna get 6 more quirks and you will need to master One for All before my brother's successor comes for you.

Damian: Wow what kind of quirks!

Nana: You'll find out when you wake up and can I ask you...

Damian: Yes?

Nana: Give Shigaraki a quick death...

Damian: What! No! I'll try to save him first...

Damian then just woke up and felt like his body gotten more adept all of a sudden.

Damian: Ok day one! I'm gonna train my quirks and body to defeat Shigaraki!!!

2 Years Later...

(Change the suit to Reddish-Blue and Midoriya to Damian.)

Damian is seen on top of a rusty broken bridge and puts his hood on as the rain and cold, smoky breeze blows bye. 

The time is currently 9:11 PM as Damian checks his phone. Damian is seen using his awakened Danger Sense on the city and can't find Shigaraki but can sense movement across the city at a industrial complex.

Damian: Shigaraki...

Damian jumps off of the bridge and Floats towards the industrial complex and finds a man covered in a red cloak, trying to break into the industry.

Damian: Hold!

The cloaked person turns around.

???: Damian?

Damian: Wait... Mirio?

Mirio takes off his cloak and runs over to Damian and hugs him tight.

Mirio: I thought... I was the only one left..... *Tearing up*

Damian: How did you survive?

Mirio stops hugging Damian as he also stops crying.

Mirio: I guess my quirk does a lot huh.

Damian: So that's how...

Mirio: How did you survive?

Damian: I used my quirk, Float.

Mirio: You have Midoriya's quirk? Is he still alive?!

Damian: No...

Mirio: So... It's just us?

Damian: I guess so... I know a safe place. But first what where you doing here?

Mirio: Industrial supply's to make a safe zone. I was constantly on the move because he kept finding me...

Damian: Who?

Mirio: Shigaraki.

Damian: How about you take the lookout and I'll find some supplies and we'll go back to my place?

Mirio: Not a bad idea.

Damian walks over to the door of the industrial complex and kicks the door down easily. Damian starts searching for supplies and 10 minutes later Damian can hear talking outside so Damian walks to the window and looks out to see a sandstorm.

Damian: Mirio is probably talking about a sandstorm... I should just ge-

Damian cuts himself off as his Danger Sense alerts him and he looks closer to the sandstorm to see some movement in it which sent chills up his spine.

Damian: He's here!!

Mirio who's outside hears this and gets into a fighting stance. The ground shakes and a beast looking thing with hands and arms all over it jumps in front of Mirio.

Mirio: Shigaraki!

Shigaraki: Hello... Mirio.

https://youtu.be/2s2kMNeUT50

(In Case Video Doesn't Work Here Is the Link:https://youtu.be/2s2kMNeUT50)

Mirio is seen shaking to his core and Damian is also seen bursting through the window up high in the air and uses Blackwhip to attach to the industrial smoke pipes. Damian uses One for All Full Cowling 100% in conjunction with Fa Jin, Float and faster than a bullet, Damian kicks him in the face as Shigaraki hovered in the air.

Shigaraki is seen skidding across the ground and finally landing as he gets up from the ground.

Shigaraki: *Venomous tone* Damian...

Damian then looks at him with a surprised look.

Damian: "It's him... But he's no longer a human... He's... A monster!"

(Pause at 0:32.)

Shigaraki: Isn't it the 10th user...

Shigaraki is seen using his mutated arm and Grabs Mirio by the throat.

Shigaraki: Not another step or he'll die too.

Damian: *Growls* Let him go!!!

Mirio uses his quirk and gets out of his grip and tries to get away but Shigaraki touches the ground and it decays the ground which Mirio didn't predict, and he got caught in it, but Damian used Float and grabbed him with Blackwhip.

Damian: Mirio!!

Damian brings Mirio closer and holds him tight.

Mirio: *Decaying* Damian... This is it for me... Promise me one thing...

Damian: *Tears up* What is it?

Mirio: *Smiles* Save a million for me.

Just as Mirio said that he decayed to dust and Damian lands on the ground in front of Shigaraki and falls on his knees.

(Unpause the song now.)

The sky suddenly started forming clouds then started raining as the water dribbled down On the two.

Shigaraki: Let's finish this...

Damian: GRAHHH!!!!!

Damian turns around in rage as Blackwhip goes in front of his mouth as well in anger and he is seen using One for All Full Cowling 100%, Fa Jin, Blackwhip, Gearshift and Smokescreen.

Shigaraki leaps into the air and drives down a punch but Damian blocks it with Blackwhip and wraps it around Shigaraki's arm and Blackwhip is infused with Fa Jin as it looks super charged and it takes the form of a chain which he then throws Shigaraki into the air along with some rubble from the force. As time almost seemingly slowed down, Damian was standing on a falling rubble and is charging his fist with Gearshift and Damian leaps off of the falling rubble and punches Shigaraki in the stomach sending him higher and Damian, as if he almost teleported behind him did a Manchester Smash and Damian does a bullet sky dive closing in on Shigaraki with a fist ready.

(Change Midoriya to Damian and have Midoriya and All Might with the users.)

Damian: Third gear... Second gear..... TOP GEAR! ONE FOR ALL 1000000% UNITED USER'S SMASH!!!!!

Damian: "I thought there would be a shred of hope for you... But there's nothing left but a monster who destroyed Japan....."

Damian then sends his strongest attack and completely punched a hole in Shigaraki's chest which "killed" him on impact, Damian's fist went through Shigaraki and destroyed literally everything behind Shigaraki and split the atmosphere.

Damian pants heavily as the rain stops and the sun starts to rise, and Damian sticks up his broken and ripped arm up like All Might. As Damian walks away with hollow eyes not knowing Shigaraki's body moves a bit and he sends out a Rivet Stab and stabs Damian in the leg, some weird red aura glows and stops, Damian turns around and stomps on Shigaraki's head thus completely crushing it and killing him.

{A Few Months Later.}

Damian has been wondering around for a few months now and still looking for any survivors, but found none as usual but he kept exploring and then all of a sudden, a portal opened up and it started sucking Damian in and he tried to use Blackwhip and Float to get out but it's pull was too strong, and he got sucked in. Damian looked around and saw galaxy's, universe's, multiverses. Then he hit the ground and fell unconscious, Damian woke up an hour later and looked around to see he's in a forest. Damian uses Float and fly's up to see he's in Japan but 3 or 4 years earlier. 

Damian looked around and saw a city, so he flew over there and realized this was Hosu city. Damian keeps looking around and sees a villain that turned huge.

Damian: Oh, I know now this is when Midoriya saw the new hero Mt.Lady? I guess I'll make an entrance because he's probably in the crowd!

Damian flies towards the villain and uses Blackwhip to tie up the villain.

Damian: "One For All 100%!!"

The crowd notice Damian and his Blackwhip.

Damian: MANCHESTER SMASH!!

Damian flips forward to bring down an axe kick to the giant Villains head which knocks him out and down, Damian then quickly uses Blackwhip to carry him before he fell on anyone.

Crowd: WHO IS THAT HERO!!?

Then the villain shrunk, and Damian let him go. He was on the ground unconscious, then Damian's Danger Sense goes off and he dodge's a giant hand from grabbing him.

??? Pov.

???: Whoa a new Vigilante but with different quirks!?
