In a world where one man can obliterate massive monsters with but a single punch it's hard to believe anything is out of reason. Whether it be psychics, mutants, cyborgs, aliens, or whatever else one's imagination can think of, when you have someone like Saitama around, anything seems possible. This is the exact thought that entered King's mind when he first met Saitama, seeing someone who was like him in so many ways become the world's strongest hero was admittedly inspiring, hence why he became Saitama's "sidekick". And while this was how the world and the other heroes saw him and he was fine with it, all that mattered to him was that one day all of his effort he put forward to showing Saitama his kindness and respect hadn't gone to waste is what really drove him towards becoming strong.
To no longer need to rely on others to save is life when it was in danger, to no longer have his whole body turn into jello when the slightest bit of trouble emerged, to be able to stand tall with his head held high instead of between his legs in a dry heave, this was the dream he sought to obtain. But before today that's all it was, a dream concocted by a man simply wanting to better himself and repay the countless times his good friend had saved his hide, to prove to himself as well as the world he could be more than a coward and that maybe just maybe, he too could be a great hero. This is why despite the pain he felt in this moment, despite the blood that came from his body, he had one of the proudest most joyful smiles he ever had present on his face, as for the first time in his whole he was standing his ground in a fight instead of running away from it.
And while he was in no way close to being as strong as Saitama, which to be fair no one was, even he was surprised by the amount of strength, speed, and awareness that he apparently possessed. The fight between him and G4 had only just begun a few minutes ago, but even so he had managed to not only dodged every swing of the sword the massive machine sent his way, but he also managed to put a decent bit of dents into it. This is where the blood came from, for while his foe hadn't landed a single blow yet he was still punching hardened metal and was by no means "super", so with each punch he bruised his fists more and more until he began to draw blood, which his opponent did take notice of.
"Heh, you're bleeding from your own attacks?" It questioned as it gestured to it's body "You've only managed to cause a few light dents in my frame, and yet you're already injured." It taunted as it pointed it's sword towards him "I will admit this, you've done a good job of dodging my attacks so far, but how long do you honestly believe you can keep this up?" It asked.
"Until I kick your ass..." King answered trying to be cool, causing the other to laugh.
"Amusing, but pathetic." It told him as it readied it's blade for another attack "At this rate, I'll have little worthwhile data from this experience." It taunted again as it swung it's sword.
At one point in time King would've died right then and there, as the sword had moved with such speed and power it not only was near impossible to see but it was strong enough to slice clean through the nearby lights, signs, and vehicles without any issue. And whether it was thanks to the training Saitama had him do, or perhaps it was the experiences he shared with the others during their hero work, he not only managed to dodge the blade successfully but he also before the attack was finished dashed up to G4 in order to land another blow. Pulling his fist back and sending it forward with as much power as he could possibly muster, while he didn't send the other flying down the street he did make it skid back a few feet, and the dent he made this time was his biggest yet. Sadly this attack wasn't without cost, as the moment it connected King could feel three of the fingers on that hand break violently, meaning that if he chose to use that hand for another attack he would then break it, rendering it completely useless.
But before he could focus on his worsened injury even more G4 was quick to retaliate, dashing forwards to not only regain the lost ground but to also to try and land another attack. Making sure to keep his eye on the sword for any slight adjustments in it's path, King waited for the attack to come but found that the sword wasn't the intended offense, but instead was a distraction. Knowing that he would be expecting to dodge the sword yet again, G4 used it to keep his attention as it used it's own body as a battering ram of sorts, hitting King at near full speed and sending him flying through the air down the street. Going right through the front of an office building and tumbling across the floor until he hit the reception desk, he couldn't keep himself from regurgitating blood as the blow had done quite a bit of damage.
"Sh-Shit..." He coughed as he dragged an arm across his mouth "H-He broke most of my ribs..." He wheezed as the injuries he sustained was making it hard for him to breathe.
Trying his best to get to his feet as to try and prepare a defense, King would soon find himself lifted from the ground by G4's hand, before he was then thrown back outside onto the street. Bouncing roughly a few times on the road before painfully skidding to a stop, besides his sleeve being torn apart and some of the skin on his arm being torn a bit as well, he didn't sustain any new major injuries.
"Is this really all you have to offer?" G4 questioned as it slowly approached him, seeing no need to hurry "You're supposed to be the world's second strongest, and yet you're not even in the top five." It taunted yet again as it soon came to a stop in front of him "How are you even S class?" It asked.
"T-To be honest...I have no idea..." King admitted with a chuckle as he coughed up a bit more blood "It just sorta happened...because I knew Saitama..." He explained as he got to his knees "B-But I promised him...that I wouldn't let him down...that I would show him...I could be strong..." He went on as he got to his feet "Which is exactly what I'm going to do...by beating you..." He told the other as he brought his fists back up in front of him,
Or at least he would've, if the moment he finished speaking he wasn't immediately sent flying into another building, this time to his left. But unlike before where he had been rammed, this time what sent him flying was actually G4's sword, as when the other attacked King due to his injuries could only try and block it. And while amazingly he did manage to block it it wasn't without cost. Whether it was due to his body's own resilience or perhaps the sword was a bit dull, instead of being cleaved in half he only had two large gashes in his forearms where the sword made contact.
Unfortunately these gashes were deep enough to put his arms out of commission, leaving him completely defenseless. Unable to do anything other than watch as G4 approached him and picked him up once again, even in the face of his final moments King still felt no fear, which despite his pain caused him to smile.
"Is something amusing?" It asked him, finding his expression to be strange given the situation.
"I-I'm not afraid..." He muttered beneath his breath, as his smile grew a bit bigger "For the first time...I'm not afraid..."
"Good for you." G4 replied as it raised him above his head, preparing to throw him straight towards the ground "Too bad this will be both the first, as well as the last time." He told him.
Knowing well there was no point in struggling as he could barely feel anything to begin with, King simply closed his eyes and waited for the inevitable.
"I'm sorry Saitama..." He thought as he took a deep breath "But at least...I gave it my all..."
After a few seconds more of being held in the air G4's arm went flying down towards the ground and with it, King's whole world went dark.
