Izuku Midoriya: the cybernetic Villain

meet Eri/the fight

once the four return to the hideout...the others were waiting for the results
soon Izuku walks in
Dabi: "so..how'd it go" 
Izuku: "welcome to the deadly alliance" 
Dabi: "did you let Tomura name it...really?" looking at him 
Shigaraki: "it seemed fitting...and yes..we have made an alliance with the Yakuza" 
Toga: "ooh will they also get cyberware?" 
Izuku: "good god no....the leader already was horrified that he was talking to a machine." 
Dabi: "figures." soon he notices a little shadow and sees a kid 
Toga squealed along with Ochako 
Ochako: "oh my god she's so cute!" 
Toga: "i just want to pinch those wittle cheeks" 
Izuku: "this is Eri....the gift we received from the Yakuza" 
Dabi: "they gave you a kid" 
Shigaraki: "it was that or money that could be traced" 
Dabi: "fair enough" 
Izuku: "where's aunty?" 
Dabi: "she's up stairs sleeping...of course it's the first time in years that she's felt safe...and now for the tot here" to which Eri hides behind Jirou 

flashback 40 minutes earlier
little Eri was happy that she is able to get out of this horrible place...the needles...the devices he used on her...but when she saw Izuku for the first time...she was scared...fearful looking at him...he looked like one of those monsters in her nightmares...but she sees the lady right next to him...the one with the mask...through her visor she could see her eyes...she was kind and gentle...she knew she could trust her...soon she heard Overhaul bringing her close to Johnny Silverhand he calls him... 
Izuku: "so...eri...welcome to the league" 
Jirou kneeled down to her level: "hey...it's alright we're here to take you back to our home...alright?" and she nods the car ride was odd...Johnny sat by her and Jirou was holding his hand...did they like each other? are they really close? like a mom and dad?
Jirou soon takes off her mask and she smiled softly at her reassuring her that everything will be okay...she looks at Izuku next...instead of the steel cold glare that would even put her former father in his place..instead she sees the warmth look on him...even though the rest of him was cold...he felt like a metal bench...cold the moment you sit or lean on him maybe things won't turn out the worst 
flashback ends

Eri is still nervous with the rest of the league but the brown haired lady seems to be good friends with Jirou...she looks around to see Tomura or the pale man she calls him playing a game...there was this big man wearing a red cap and overalls his big mustache and shouting gleefully jumping around these platforms...she walks to the TV and watches him play...Jirou approves of it and she watches her incase it gets a little tense Izuku meanwhile went to his lab...probably to install more cyberware in himself...dabi was drinking as usual and Kurogiri was preparing Eris room for her to stay the night in...
Izuku: "the plan was simple...take the bait or possibly install a daemon into his hardware...but instead we got the better option...becoming allys with each other showing one another that they can work together...peacefully...of course i am still wary of Overhaul...i scanned Eri in case she had any type of tracker on her...but there was none...and i double checked the moment we arrived at the base...her quirk is an odd one...the ability to reverse 'time' by that i mean when she touches someone she could reverse their age...or infact kill them by turning them back before they even became a thought...it's dangerous and she is quite timid about it...don't blame her...she seems to warm up to Jirou well...me..not so much...well i don't blame any child that meets Johnny silverhand in the flesh or machine...tomorrow we have something in store for the heroes...and i will be with Overhaul the majority of it...the plan is simple really the heroes are going on their interships with their heroes and is gonna go into their second semester...we gave them a hell of a first semester...they stand no chance...soon they will have no choice but to bring children into their little war with us...shows how pathetic and desperate they really are...and the golden opportunity to recruit more members possibly...another horrific mistake they made...is the idea that there's a traitor in their ranks...thinking we planted a spy...in their defense it seemed reasonable..but as you see..i don't need a spy...i get everything from their networks...they never thought to ever improve their security. It's quite sad honestly. so now...now the real fun will begin...Overhaul and Tomura will make a grand appearance soon." soon he turns off the camera and then turns it off...he looks at the Ashura...he made more bullets...of course it was still on priority setting number 2...and number 3 will aim for the foot or hands...and number 4....the head...it will pull off a headshot...and he likes it. he should've used it on Izumi and her friends....killing one of those pest would be beneficial.. oh well next thing he does is he starts doing some adjustments to his legs...he made some nice little modules for it...a power enforced muscle with some propulsion jets in them...allowing him to jump higher than usual...working on his left leg he installed it...next was his right....opening the leg revealing all of the wirings and mechanics that would be much more complicated than building a rocket...soon he hears the door open..and he sees Eri walking in...he thought it locked itself...Eri was frightened a little seeing his leg 
Izuku: "*sigh*" he doesn't know what to say...she walked up to him slowly...and she starts to cry..
Eri: "....hurt?..."  oh she's worried for him
Izuku: "no...i'm not hurt Eri...this is how i am...i'm....different than most" 
Eri: "is it.....a quirk?" god curse this childs innocence 
Izuku: "no...it's not a quirk" 
Eri: "robot?" and he chuckles 
Izuku: "yeah...something like that" soon he brings out the jet
Izuku: "you don't have to look." and she looks away and he installs it...finishing it up he clicks on a lever and the leg closes itself 
Eri looks back and sees it normal...again Izuku stand back up 
Izuku: "see...like nothing happened" and she was looking at his fingers and points at it
Izuku: "these are called gorilla fist" showing it to her
Eri: "are...they don't look like gorilla hands" tilting her head in confusion 
Izuku: "well...you could say it makes me as strong as a gorilla" 
Eri: "oh" getting it now
Izuku didn't want to show anymore...he didn't want to freak her out enough 
Izuku: "eri...why did you come in here?" 
Eri: "because....you looked...sad?" she told her 
Izuku: "i looked sad?" 
Eri: "you...look hurted...like me" she said to him and he was surprised at this 
Izuku: "well...you don't need to worry about me Eri...i'm holding on my own" 
Eri pouts: "but you're not alone...you have mama" excuse me?
Izuku: "mama...are you talking about Jirou?" and she nods 
Eri: "and mama hold your hand so...your my new papa right?" asking him...
Izuku was stunned he never thought...he would be asked this...now...he never knew what it was like to be in a normal family...well their family is nothing but normal...but they all understood each other
Izuku in long time did something he thought would happen....he cried....although due to the cyberware he can't cry...but the artificial blood he has dripped out of the eyes...he looks down in shame...her father is a machine....how could she even bear to look at him like a parent? but then he was enveloped in a hug her small arms barely cover his torso...he got down and hugged her tightly...but he was gentle not wanting to harm her...like she was made of very thin glass..he will never let her go...they want to take her...they will have to go through him and the league.
