The Viper hero. My hero academia x male oc (stopped until season seven)

The battles begin

Todoroki wanted to talk to Nagisa and Izuku

Nagisa: ok you've got us here now what

There's an awkward silence

Todoroki: I was overwhelmed and it made me break the promise I made to myself along time ago
Nagisa: sorry what did you do
Todoroki: I used my life side but I suppose you weren't there but all of our team mates couldn't feel it, it was only me I could sense your true power it felt like all mights quirk
Izuku: well yeah is that all
Todorki: I'm saying that power coming from you felt the same as all might, what I'm saying is are you really all mights secret love child or something
Nagisa and Izuku both get blank stares
Nagisa bursts out laughing: haha todoroki that's no way near true
Izuku looks bewildered
Shoto: well are you
Izuku: no,no,no that isn't it at all but that's exactly what I'd say if I wasn't so you probably won't believe me no matter what I bet..anyway I promise you've got the wrong idea and why would you even think that about me
Shoto: that isn't it at all is interesting wording it says that there is something between you two that your not supposed to talk about
Nagisa and Izuku look away
Shoto: my father is the hero endeavour you must Jane heard of him which means you know he's the number 2 hero so midoriya if your connected to the number 1 hero all might in some way than that means I have even more reason to beat you, my old man is ambitious he aims for the top he used his power to make a name for himself as a hero but he was never able to best all might so the symbol of peace is living proof of his failure he's still at it though trying to take down all might one way or another

Izuku: I'm not sure what you're getting at

Nagisa: yeah spill what's going on

Shoto: have you ever heard of quirk marriages

Nagisa's eyes widen: don't tell me
Naga: yeah I figured this guy had a tragic backstory he seemed like the type

He explains quirk marriages

Shoto: and now he's raising me to usurp all might. It's so annoying I refuse to be a tool for that scumbag in every memory of my mother I only see her crying I remember she called my left side unbearable, before she poured boiling water on my face

Nagisa and Izuku are both scared now
Naga: (alright then that's something)

Shoto: midoriya the reason I picked a fight with you was too show me old man what I was capable of doing without having to rely on his dammed fire quirk you see I'm going to show him that I reject his power and I can take first place without using it

Shoto: you both are obviously connect to all might but no matter how fearlessly you come at me in the future I will defeat you using on my right side

Nagisa: (he reminds me of me but it's different)
Naga: yeah well you don't have to hold back you could go all out
Nagisa: (they've all seen why I can't do that)

Walks to todoroki

Nagisa: you shared your ambition now let me share mine, as you've notified my quirk is different from most peoples in this school it looks villainous and scary you saw what happened at the usj my whole life people have been scared of me because of the power I was born with so my desire is too chnage how the world views people with quirks like mine

Shoto: fine bring it on

Then Izuku runs up as Nagisa is walking away

Izuku: hey wait! I'm only here because others have supported me I've been really lucky in fact I've had even more help since I came to ua, you remind me of someone you know that holding back because of a personal reason. All might is constantly saving people with a smile and I want to be just like him I know my motivation my seem stupid compared to yours or my brithers for that matter but still I can't lose this either I owe it too everyone who has supported me too try my hardest you declared war on me earlier well right back at you I am going to beat you
