"He's going to reveal his secret now?" Genos breathed. Saitama had told you how he achieved his strength when you first encountered him, but honestly you never got any super specific details on it. You only guessed that he went through some tough training.

"What is he doing? That idiot...why is he telling his enemies!?" You hissed in a whisper.

"I'd like to know too," The man Kabuto had in his grasp when he first attacked you said as walking up to you guys and holding his bleeding arm.

"Huh? Who're you?" Saitama questioned.

"I am Genus," Responded the man.

Saitama still looked confused as hell but shrugged. "Well, fine. Listen up."

"This is dangerous," Genos mumbled in your arms. "He can't let these guys know his secret!"

You sighed in defeat. "I guess we'll just have to trust him." Genos didn't seem satisfied with the response, but ultimately there was nothing either of you could but hope for the best.

"First, what's important is to make sure you stick to this intense training regimen," Saitama informed promptly.

'Training? No surgical modifications, genetic enhancement, or secret drug? But training?' Genus's baffled mind questioned.

'What kind of training...?' Carnage Kabuto inquired in his thoughts.

"Genos, if you want to achieve great strength than you have to keep doing the regimen, no matter how hard it gets," Saitama advised. "I was able to get this strong in three years."

"ONE HUNDRED PUSH-UPS, ONE HUNDRED SIT-UPS, ONE HUNDRED SQUATS, THEN A TEN KILOMETER RUN, EVERYDAY!!!" Saitama shouted with the most serious face you had ever seen on him. You noticed that everyone else in the room was in pure shock, but in the back of your mind you were thinking 'That's it???'

"And of course make sure you eat three meals a day. Just a banana in the morning is fine," The bald man continued. "But to train your spirit, never use the A/C or heater in the summer or winter. In the beginning, you'll wish you were dead. You might start telling yourself, 'what's the harm of taking a day off?' But I wanted to be a strong hero, so I preserved every day, even if I vomited blood. Even when my legs felt so heavy I could barely move, I kept doing squats. And when my arms started making popping sounds, I pushed myself off the ground for each push-up."

You winced at this, recalling some disturbing experiences of your own with exerting yourself past your limits. You used to be forced to run aimlessly in mazes for days straight until the scientists decided that they had had enough 'research'. Anytime you would try to stop, you got a high voltage shock of 100 milli amperes, 5 times as much of electricity that it would take to kill a normal human. You remembered these memories from what Saitama said because every time the labs would drill you through their experiments, you would find random scars, bruises, and strange clicking sounds that would sound whenever you moved your body.

"One year later, I noticed a change," Saitama went on. "I was bald..... And I'd gotten stronger! In other words, you have to train so hard your hair falls out. That's the only way to become strong."

"If you're messing around with a 'new human race' and 'evolution', you'll never make it," This he directed toward Genus. "Human strength lies in the ability we have to change ourselves!"

You smiled at this statement while again the others just looked flabbergasted by Saitama's speech.

'W-what...?' Genus breathed.

'Is this guy.... for real?' Kabuto thought with wide eyes.

"Sensei....you are so..." The Genos resting against you suddenly started to stand, much to your surprise. "FULL OF SHIT!!!"

Your eyes flew open to the smol cyborg you had that was very cute and respectful up until now. Holy shit....

"Huh?"

"That's nothing but a standard training regimen! And it's not even that hard!" Genos shouted angrily. "I...I have to become stronger! I didn't ask to study under you to hear jokes! Saitama Sensei, your power is clearly from more than physical training! I want to know your true secret!"

"Genos..." Saitama said in a bit of a sigh. "You may not believe me but that's all I really did."

"Well, it seems legit..." You muttered.

"Oh, I see..."

You all turned to the enormous who had stomped onto the white tiled floor. You raised an alarmed eyebrow when you saw the skin on Kabuto begin to flex and scrunch up.

"No, Carnage Kabuto!" Genus called out.

"Fine, don't tell us your secret," Kabuto growled as his body bulged and snapped as his muscles expanded.

"Stop! You'll go on another rampage!" Genus said desperately.

"I bet you're not stronger than me anyway!" Kabuto snarled at Saitama.

"Saitama, get away from him!" You warned as red alarms and ringing blares sounded throughout the white room. The doors you had come from began to shut and lock up, trapping you in the room with the growing monster.

"But, since you pissed me off," Kabuto's animalistic voice rumbled. "I'll make sure to kill you extra slowly."

The beast's body had altered and changed into a purple mass, the indentations of his muscles were lined with neon green. "CARNAGE MODE!!!"

The white room suddenly adjusted and formed into a dark red grid. It seemed like you guys were being suspended by some unknown force because the ceiling and floor looked like a never ending vent of red lasers.

Kabuto reared his ugly sharp-toothed face at you. "When I get like this I lose control for a whole week and my lust for death cannot be quelled! After I kill you and the girl, I'll head into town and go on a killing rampage until next Saturday!!"

Saitama abruptly lost his bored expression and was replaced by a look of panicked shock.

"And I'll start with YOU!" Kabuto launched forward and caught you completely by surprise. His hulking fist rammed into your face, sending you bouncing off the walls. The attack was so unexpected you didn't have time to scream.

However, someone else did as they snapped out of their horror. "(Y/N)!!!" Saitama yelled. Even Genos was concerned for your safety.

You blinked away your confusion and jumped into action. You arched your back and extended your wings to somehow try to halt your bullet speed ricocheting off the walls. But as soon as you did, Kabuto suddenly appeared behind you.

His large hand circled around your waist and thighs, then threw you harshly down to the end of the room. Since the illusion made it seem like there was no drop off, it hurt a lot more when your face crash and dented the space where the invisible floor was.

"AHAHAHA! Some power you have! And you had the gall to say I was nothing!" Kabuto cackled, then turned to Saitama. "Now it's your turn!!"

"(y/n)!! Are you alright!?" Genos said as he ran over to you. You couldn't respond quickly because you were still trying to recover from the mind jumbling impact.

Saitama was looking to you to see if you were okay, and was distracted when Kabuto punched him into the air. As your arms trembled to get yourself up, you heard the roof cave in as Saitama crashed through it. You glanced up and saw him begin the fall back down. But not until Kabuto punched him into one of the walls, causing him to bounce around like you did.

"(y/n)! Hey, are you okay?" Genos asked as he eventually ended p dragging you up.

"Saitama..." You whispered, not taking your eyes off the fight. Kabuto was close behind Saitama, slamming his fist into the walls that broke apart into dark red cubes. Saitama dangled around, taking each hit.

"What is he doing...?" You inquired quietly.

Saitama raised his arms up in defense as Carnage Kabuto unleashed a chain link of blurry punches. "DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE!!!!!"

'In Carnage Mode, he rages like this for a whole week!?' Saitama exclaimed in his thoughts. 'For a whole week!? That would mean today is Saturday...which means...which means....'

"It's all over," Genus smirked. "There's no one who can stop him."

You grinned cockily. "You sure about that?"

"TODAY'S BARGAIN DAY AT THE SUPERMARKET!!!!" Saitama shouted. And, with one punch, Carnage Kabuto was decimated to gushing piece of purple blood.

Genus's jaw dropped.

But Saitama was still screaming like his life was ending. You laughed and got up to your feet. Doing the best you could, you ran over to the bald male.

'Just who the hell is this guy!!?' Genus said as his eyes bugged out of his skull.

"GYAAAAH!!! I'M MISSING GREAT DEALS!!!"

"Aw don't worry, come on, there's always next Saturday," You patted his back.

"Wait, what is he—"

"I'm pretty sure he's upset about this," Fluffy haired Genos informed the bleeding scientist, holding up a flyer with several coupons on it. After giving Genus the paper, Genos walked over to you comforting Saitama. "Sensei, the store closes at 10 PM. That's about 4 hours away. If we hurry we can make it."

"See? Get up or we're gonna miss it!" You smiled encouragingly.

"I'll make it if I hurry!?" Saitama said, standing up quickly.

"Yes!"

"Let's go! (y/n)! Genos!" Saitama instructed, turning on his heel and toward one of the now white walls.

"Yes, Sensei!"

You grinned happily as Genos let you get on his back as you guys ran through one of the walls Saitama had punched in.

"I think I'm done with evolution..." Genus mumbled to himself. "It appears...I'm the one who must change."

I apologize for this being late. Stupid Wattpad wouldn't let me update. Wtf Wattpad!? I thought we were bros! >:(
