Well, I did not plan on updating this fic so soon, but the new My Hero Academia movie has gotten me into a MHA mood! So...here's a new chapter! ^^
Also make sure to check the bottom notes for something important

Chapter 2: The Cyborg

The next morning, Saitama sat in his living room and nervously tapped his fingers together. Looking out the window, he sighed as he didn't spot anybody. "Okay...safe...he doesn't know where I live so he will not show up," Saitama muttered quietly to himself in relief.

He still could not believe he agreed to be that kid's sensei! He didn't know anything about teaching! Hopefully, he could keep from running into the kid again. The last thing he needed was some kid following him around while trying to learn how to get stronger like him. Plus, what would his mother say if she saw the kid? She didn't know about him being a hero. Maybe he should tell her? No, she worries too much. It's not like he could get hurt.

Leaning back on the couch, he stretched his arms before checking his phone. Turns out the phone still worked properly, there was just a large crack spread along the screen. Since it still worked, he would not be wasting money on a new phone while he had a perfectly good-working one. Scrolling through his text messages, he saw one from Midoriya about running into All Might. The image of a shocked stiff Izuku ran through his mind which caused a small laugh to escape his lips before closing the app.

Grabbing the remote control, he turned the television on and switched between news channels to see if there was any news about villain attacks or disasters. He was bored, and he did not feel like re-reading his manga for a third time.

"I really need a hobby," Saitama muttered as he groaned into his arm. Hearing the door bell, he sighed while standing up and walking over to it. Why couldn't his mother be home? He was not fond of the neighbors plus he hated having to deal with door-to-door salesman. They were so annoying.

"Master!" Saitama froze in place as he opened the door halfway. Looking down, his eyes widened at the sight of a young boy. From his young face, Saitama could only guess that he might be eleven or twelve years of age. He didn't notice before, but the boy's arms looked like they were half-made of metal with the skin ending halfway down both arms. His neck also seemed to have metal peeking out from the bottom of it. Blinking in confusion, the only thing that could come to mind was:

"You came?"

After stumbling over to the side, Saitama decided to invite the boy inside. Considering he somehow found out where he lived, he might as well let the kid in. Plus... "Do not call me master."

"Sensei then!" the boy immediately replied causing a vein to begin painfully throbbing in Saitama's forehead. Opening his mouth, he let out a sigh as he could tell arguing over this point would not help him in the long run. Shaking his head back and forth, he looked up and flinched at the unnerving stare that the boy was sending his way, "Sensei! I have a question!"

Looking back in confusion, Saitama gestured for the kid to speak, "Did your Quirk cause you to lose your hair or do you have some kind of armor implanted in your skull?" Growling, Saitama slammed his hands down on the table which earned a groaning sound from it.

"So I'm bald! What of it?!" Saitama angrily replied while glaring at the kid who continued looking back with an emotionless gaze.

"You want to know my problems?" The kid asked Saitama who quickly shook his head no. He was not in the mood for some kind of backstory explanation right - "When I was four, a villain with a robotic Quirk attacked my town and killed everyone, including my family." Damn it.

"I forced myself to stay alive even though I could feel myself on the edge of death. Luckily, a kind scientist found me and took me in. He saved my life by replacing my broken body with cybernetic parts that would help keep me alive. As I grew older, I would replace the older parts with newer, stronger ones. I plan to find the villain who killed everyone I held dear and kill them so that they will be avenged. And to do that, I need to become stronger. Possibly even stronger than All Might himself. So when I saw your incredible power the other day, I knew that you'd be the perfect teacher for me. With your teachings, I can grow to become someone so powerful that I can defeat any threat that comes my way, and he will not be able to stop-"

Saitama felt his mind drifting away as it seemed like the life was draining from his body. Is this what death felt like? This endless torture that just. won't. end! "SHUT UP! KEEP IT TO TWENTY WORDS OR LESS!"

The boy froze in possible shock before letting out a small cough and fixing his stance. "Sensei, please teach me how to become stronger." Sighing in relief, Saitama finally propped himself back up in a proper sitting position. Looking at the younger boy sitting across from him, Saitama finally decided to speak up.

"What is your name?" Saitama asked the boy who looked at him for a moment before replying.

"Kuseno, Genos." Saitama nodded back in response.

"Genos-san, how old are you?" Saitama asked, genuinely curious after finding out that the boy is a cyborg so he could actually be older than he looks.

"11 years old."

Well there goes that thought. Coughing into his fist, Saitama looked at him as seriously as he could. "Genos-san, I was eleven years old myself when I began my training. It took me only three years to get as I strong as I am now."

Genos's eyes widened in shock as he stared back at the older boy in front of him. "Just training? No body modifications or enhancements?" he asked while leaning closer. Shaking his head, Saitama rubbed the back of his head while shrugging lightly.

"Nope, I just trained. I was Quirkless so I knew that I would have to train as hard as I could to become a strong hero," Saitama explained in a nonchalant voice while ignoring the astonished face the cyborg boy was sporting. "Anyway, it worked against me in the end. Now everybody I fight goes down in one punch. It's so irritating." He groaned while dragging his hand down his face. He was not completely sure why he was telling this boy he just met this when he does not even tell Izuku about this, but the kid looked like the kind of person who wouldn't mind listening to him complain.

Sadly, the boy decided to cut him off as he slammed his own hands down onto the living room table that separated them. "You're Quirkless?!" Genos shouted at the top of his lungs. Saitama just looked up at him with his usual blank face.

"Yeah, so?" he questioned the boy who slowly fell back down in his seat trembling. Saitama looked at him with an curious yet slightly concerned face since he seemed so shocked? Scared? He wasn't sure. He didn't expect Genos to leap over the table and bow repeatedly.

"Please sensei! Please! Take me on as your disciple! If you can become this strong while being born Quirkless than you could train me until I become incredibly powerful!" Genos practically begged while continuing to bow. Looking back at the boy with a worried face, he looked out the window to make sure his mom was not back from work early.

Looking back at Genos, he could see the desperation in his robotic pupils (weird) and he did not want to be the person to crush his dreams, but what could he teach the kid? The kid is a cyborg, and he clearly has no muscles leftover to train with his exercise routine. Great! This was not how he was expecting his day to go!

Mob! Mob! What do you want?! Mob! Mob! Why do you want?! Mob! Mo-

"Hello?" Saitama answered his phone while cutting off his ringtone. Holding a finger up to Genos to ask for a moment, "Izuku? Yeah? You want to meet at Dagobah beach? Why? For training? You want to train together? Uh..." Looking over at Genos, he got an idea, "I'll be there in a moment, but do you mind if I bring a guest? I met someone yesterday. Yeah, thanks. Bye."

Putting his phone back up, "Genos, my friend just called to ask if I wanted to training with him. I need more to consider your proposal, but in the mean time, I'd like you to meet him. He's very smart and could help you out with ideas for your...body."

Genos's face lit up before nodding excitedly. Sighing, Saitama walked back to his room to change out of his pajamas and into his 'Oppai' hoodie and a pair of jeans. Pulling on his sandles, he motioned for Genos to follow him out of the house. Locking the door, the odd duo headed down the street.

Dagobah Beach

When Izuku told him that he was training, he expected some push-ups or sit-ups when he arrived. What he didn't expect was to see his friend attempting to drag a huge pile of garbage before biting it comically. Looking over, he could see that Genos was staring down at Izuku with an inquistive look.

"Yes Genos?" Saitama asked the cyborg since it was rather obvious that he had a question on his mind.

"Is this the friend you spoke of? No offense sensei, but he doesn't look like...much," Genos stated as bluntly as anyone could. Letting out a small laugh, Saitama quickly recomposed himself and motioned for Genos to follow him.

"Yeah, his name is Midoriya, Izuku. He's Quirkless like I am. He wants to be a hero so I guess he's finally training his body to become one. He doesn't know that I'm a hero though. I haven't told him yet because he's a massive hero fanboy, and I do not want to deal with that. Please do not bring it up around him," Saitama requested which earned an 'Affirmative' from Genos. Nodding back at him, Saitama and Genos walked over to Izuku who was currently spitting out sand.

"So does the sand taste good?" Saitama questioned his friend who looked up at Saitama in shock before yelping in embarrassment as he didn't hear him show up. Scratching the back of his head, Izuku stood up and chuckled lightly at his friend's statement. "So you finally decided to start training? I was wondering when you would since you wanted to be a hero and everything," Saitama nonchalantly stated causing Izuku to chuckle with an even more embarrassed look on his face.

"Yeah, I figured now would be better than never. Plus meeting All Might yesterday really...inspired me to try harder. I've been sitting back just hoping that I could be a hero without really training or trying to be one. Now though...I will grasp my dream in my hand and charge straight ahead towards it!" Izuku declared with confidence backing his statement up only to stare back at Saitama with an annoyed glare as he noticed his bald friend yawning into his hand, "Were you listening?"

"Yeah, I heard you. Sorry, I had to listen to Genos's long backstory explanation earlier, and your explanation was dragging on there for a minute. Short story though is that you're ready to train? Good," Saitama replied in his nonchalant tone which caused a sigh to escape Izuku's lips. Genos watched the back and forth between the two before deciding to introduce himself to his sensei's friend.

"Hello, I am Kuseno, Genos. It is nice to meet one of Sensei's friends," Genos bowed to Izuku while not noticing Saitama suddenly choking on air at Genos's casual use of the title he gave him. Izuku looked back at Genos in confusion before introducing himself in return. "Oh that's right, Saitama-san said that he was bringing a guest. I am Midoriya, Izuku...who were you calling Sensei?" Izuku asked the cyborg boy.

Genos directed his finger over at Saitama who groaned in irritation. "I am still considering it Genos!" Saitama angrily replied before clamping a hand over his mouth. Looking over at Izuku, he could see the boy looking at him in confusion. Looking back and forth, he quickly changed the subject by pointing at Genos, "Look Izuku! Genos is a cyborg! Gawk at that!"

Izuku's ears twitched at the statement before his head slowly turned and looked at Genos again where he finally noticed the robotic parts sticking out from the synthetic skin. Before Genos could react, Izuku was in front of him with a notebook in his hand. "Do you mind if we talk about your powers?" Izuku questioned the boy in a tone that made it pretty clear that he would not be taking 'no' for an answer.

Genos leaned back in slight shock. That...that was so fast. But he looked so weak when they arrived at the beach earlier! Sensei's friends were no joke! "R-right," Genos replied while slowly sitting down on the sand with Izuku following suit.

Hearing the two chatterboxes begin their long, long, more than 20-words conversation, Saitama decided to walk around the junkpile of a beach. He has never visited the place before, even when he was performing his training regimen.

"So Izuku is planning to grow stronger by cleaning up trash...I hope that works out for him. I don't really see what's so hard about that," Saitama muttered as he 'lightly' punched a broken refrigerator while walking by it. As he continued walking, he did not notice the fridge shatter to pieces behind him.

Continuing his walk down the beachside, he noticed an old game console. Blinking for a few moments, he proceeded to pick it up and inspect it. "This looks to still be in good condition...I'm taking it with me," he muttered as he continued his walk.

What none of the kids noticed was a tall, skeleton-looking blonde-haired man watching them from the bank. "It seems Young Midoriya has invited his friends to train with him. That's good to see! I probably should not go down there today though. I'll visit him tomorrow when it's just him training," the man muttered as he turned to leave before noticing Saitama slightly further away, "That kid...he looks familiar. Have I seen him somewhere before?"

Pondering over it for a moment, he shook his head and left the beach behind. Izuku deserved to enjoy a day with his friends before his hellish training began after all.

Okay that is the end of the chapter! I am not going to do the initial Izuku and Genos conversation over his cyborg body. There will be flashbacks later in the fic, but right now, I am going to skip it. Mainly because, lets face it, those two could talk for hours nonstop about something like that, and I need more time to think about how their conversation would play out. So for now, I'm just doing this.

Also, Genos is in the fic! Woo! He's 11. The reason? Because he's 6 years younger than Saitama in One Punch Man so I halved the age difference here. He will be 12 when Saitama enters U.A. Academy. He himself will not be a student of the academy, at least during the present time. He might enter it sometime in the future. Genos will mainly be more of a supporting character early on in the fic since the first arc is so U.A. based. I wanted to introduce him beforehand though so I can have the master-disciple relationship already established.

Now for the important thing: Regarding Saitama being in a relationship. I can see where many people are coming from when they say that he should remain single since it fits his character. In my opinion though, he could be in a relationship if he wanted to and would not be against it. Like when he thought that the Doctor from the House of Evolution was interested in him, and he replied 'I'm not into guys.' He never mentioned that he was against being in a relationship, he just wanted to clarify that he was not interested in men. The way I see it, he is too focused on finding a worthy fight to think about dating at the moment. However, if given the chance and a girl was interested in him, he could come around to being with someone. Who knows, it might help him with his depression?

Plus this isn't the exact same Saitama from OPM, he is mainly the same, but he's younger and has Izuku as a friend. Along with the other students in Class 1-A, he could find himself opening up enough to enter a relationship with someone if they like him and he likes them back. So in other words:

Saitama will be paired with someone. I am sorry if you do not like this, but I will not change my mind about it. I enjoy reading Saitama shipping fics as they are always entertaining to read thanks to his personality when it comes to most things and seeing whoever he is paired with come to terms that they like him.

If you do not wish to read the fic because of Saitama being paired with someone, I would like to thank you for reading it up to this chapter, but I sincerely hope that this will not affect anybody's opinion of the fic and that you all will continue to read it. I promise whoever he is paired with, any romance for him, or Izuku, will be slowburn and not happen for quite awhile. For Saitama it will probably longer actually.

Okay, important statement stated. Now about whether they will have harems. No, they will not. I am still unsure as to who to pair with them, but I can assure you that they will not have a harem...Izuku might be paired with two girls, but that doesn't count as a harem. I just find him so dang shippable, it's hard to contain myself. If necessary, and enough people want it, I might, keyword might, pair Saitama with two girls, but do not expect it. My main plan is still just Saitama/one girl. I would need enough requests to change it to two girls.

Please keep suggesting ideas for girls to pair with either of them. And once again, I am sorry if you do not wish to read any further because I am pairing Saitama with someone. Thank you for reading the fic up to now to anybody who decides to stop reading it because of that reason.
