Fate is in your hands izuku!

Prologue

<3rd POV>

We flip to a scene straight from hell there are buildings on flames everywhere
Everything was disintegrating
A large crater than one could realize was the remains of a city destroyed by one of the most horrendous villains in existence
In the center we see many corpses killed brutally impaled, burned or pieces of their bodies gone from existence, but this story is not of the many who suffered in this battle as shockwaves pulsate from a certain area of the crater and there we see two figures in a life or death fight

Izuku: dammit Tenko! It didn't have to be this way!

Tenko: it had to be like this we are fated to be enemies!

Izuku: fuck fate! I don't give a damn what fate says I decide my future and I see us being the family we were supposed to be! We're family dammit!

Tenko: what do you mean we're family?

Izuku: you don't know? Our parents are brother and sister so that makes us cousins, family *smiles*

In Tenkos mind the realization hits that he has a family again but he also knows he can't be with them as all he does is cause pain and suffering

Tenko:*crying* thank you knightmare for being my family

Izuku: call me izuku, we're family remember

Tenko:but we can't have that kind of future, I'm sorry but one of us is dying here whether we like it or not, I'm not in control of my body I haven't been since the start of this battle

Izuku: it's cause of him isn't it?

Tenko nods

Tenko: this will be the final battle let's make it count

Izuku: very well I just want you to know whatever happens you're still my brother

Tenko: just shut up and fight you crybaby*laughs*

Tenkos body starts charging all for one into a disgustingly powerful fist similar to the one AFO once used against all might but this one is stronger, more destructive and infused with Tenkos disintegration quirk

On izukus side he's putting more into one for all taking the power of every predecessor combined, blackwhip has been put away and putting it into a fist that begins to shine like a green star to symbolize hope and peace

Fa-Jin+One for all: Symbol of hope:perseverance

As dust picks up there is the release of a large shockwave and everything that was on the battlefield is engulfed in a large tornado dyed red in the blood of the deceased

When the air clears cameras are covering this final showdown from helicopter that struggled to stay in the air after that tornado and they see

Knightmare has a hole through his chest

Tenko: no! You were supposed to kill me, why didn't you?

Izuku: I could never kill someone important to me and also to do this Expunge!

As izuku grabbed onto tenko and used his actual quirk even though he was pronounced quirkless intense emotions throughout the war unlocked his quirk and being the nerd he is he almost instantly figured out it's capabilities but he knew to keep it secret especially from those who knew the risks of OFA

Quirk:Expunge- this quirk let's the user remove any kind of substance from a persons body or some inanimate object
Ex: he can use it on a water bottle and expunge the water out of the bottle by physical contact
Requirements-physical contact needed for activation
