Izuku has powers and transformation similar to Goku black, he's not reincarnation or trained by him just his ability to gain power every time he experiences pain, even minor injuries will give him noticeable boost in power and Yeah he's going to be...
Izuku in the moment could be seen inside his room sitting on his computer looking for anything interesting he could find to watch, while scrolling through the herotube Izuku stumble upon a footage of All might standing in front of someone who was wearing a tuxedo and the video was titled "Did all might met his match?"
Seeing this title izuku click on the video which showed the footage of all might fighting a person who as tall as him and was wearing a tuxedo.
Though the footage was only a minute and half long because after the camera get destroyed by their attacks collision causing izuku to sigh in frustration. After izuku was done watching the footage, he was about to continue scrolling but suddenly he gets a call from grand Torino and
Izuku: Sup geezer.
Grand Torino: I'm not a geezer, I'm your grandpa.
Izuku: tomayto tomahto.... Anyway what you want?
Grand Torino: nothing just wanted to remind you that only two years are left.
Hearing that Izuku groans in frustration and instantly cuts the call, He was about to put his phone away but then he get a message from someone and seeing that message izuku smirks and instantly stands up from his chair and opens his closest and takes his costume out, after wearing the costume he looks at his phone one last time before jumping out of the window.

Right now izuku could be seen walking in an alley and at the end of the alley two people could be seen standing in front of a door, when the two dudes saw Izuku coming towards them, they instantly moved away from the door and opened it for izuku to enter.
After izuku enters the door, he was able to hears faint screams and boo's of people who were present to watch the match or cheer their favorite fighter.
Inside the ring
Announcer: ladies and gentlemen this match is going to be a little different, if you are a regular watcher you might remember Taurus and leviathan match that took place a year ago where both of them fought an idiot who thought he could defeat them, not in 1 vs 1 but a 1 vs 2.... Do you guys remember that?!
After the announcer says that the crowd went silent for a second and then all of them started laughing saying "we remember that idiot" , "he was full of himself", "that idiot didn't even last 10 minutes against them" etc.
Announcer: Yes, Yes you guys are correct but... well surprise surprise, he's here again let me introduce you guys to Echo!
After the announcer says that all the light in the room turned off except one spotlight that showed izuku location, seeing the light all of them turned towards that direction and saw that izuku was standing near the gate of that underground arena. Seeing this some of them started laughing and some of them started booing which Izuku obviously ignored.
Announcer: Quite stubborn ain't ya kid?
Izuku: That how I've survived this long in my house.
Hearing that the announcer looks at him in confusion seeing the confused look on announcer face izuku chuckles and enter the ring and saw Taurus and leviathan standing in front of him.
Leviathan: So here to lose again? In all honesty I thought you wouldn't show your face ever after that last time we fought each other.
Izuku: You see the thing is I was quite busy banging your mom trying to satisfy and fuck her stress away her, so she can deal with your bullshit without any problems.
Hearing that leviathan instantly rushes towards izuku and seeing this the announcer screams at leviathan saying "he has yet to the signal to start the match!" But leviathan ignores them and went to punch izuku which he easily dodged by jumping up in the air.
Izuku then lands on the ground and looks at the announcer and told him to start the match, which the announcer did. And after hearing the announcement Taurus was about to rush towards izuku but before he could izuku vanishes from his sight. For few seconds Taurus looks around and then he saw leviathan pointing on his his head which causes Taurus to look upwards and

Seeing izuku on top of his head, Taurus's eyes went wide and instantly went to grab izuku's leg but before he could izuku bents down and grabs Taurus's horn and jumps down from his head. This action causes Taurus to bent backwards, izuku then turns around to get a better grip on Taurus's horn and throws him towards leviathan who was charging towards him.
After izuku throws Taurus away he rushes towards leviathan and Taurus who were in the corner of the ring and kick them causing them to fly out of the ring. After they crashed on the ground leviathan tried to move but found himself being unable to do so he looks up to see what the problem was and saw Izuku standing on top of him.
Izuku: say goodnight buddy.

???: Don't worry echo we are not here to take your money or anything like that.
Izuku: oh yeah, well I don't believe ya, first How about tell me what your name is...
Kurogiri: My name is Kurogiri and this is my master's successor tomura shigaraki.
