I wanted to try something new, let me know what you think (Insert generic monster background)

Please Enjoy

"Us grunts always get the worst jobs...I might as well consider myself dead."

In the rubble of a destroyed building lied a scattered remnant of what was once the mighty House of Evolution, a small half-man, half-mole hybrid. Earthwyrm, an experiment Dr. Genus considered to be a failure. Well failure was a harsh word, he preferred the word prototype, after all the data gathered from him is what lead to the eventual creation of Ground Dragon. The reason Dr. Genus couldn't see him as an adequate success was his utter lack of combat ability, other than superb digging skills he was just a humanoid creature that looked to be wearing a half baked mouse costume. It was a real shame but at least he could take solace in knowing that he helped create a more refined creature.

But we all know what happened to them.

Within a month said creature had been killed and the house wasn't exactly around anymore to accommodate those who gave up their bodies for "science". After Carnage Kabuto was set free, Earthwyrm wisely chose to tunnel away from the underground facility and hope for the best. The result was the utter annihilation of the facility and subsequent retirement of Dr. Genus, all by a bald man in a yellow jumpsuit.

It was a tough pill to swallow but what could a single "failed experiment" do? Avenge the house by throwing himself at a man Kabuto couldn't even scratch? No, weaker creatures like himself could only look for more outcasts to hide with. With some luck he did manage to find some that accepted him without question...Unfortunately they were more than happy to treat him as nothing more than an expendable asset.

The Monster Association was less of a home and more of a sweatshop, with the lower tier monsters like himself taking the most dangerous tasks that could be given. For the most part, monsters like him were seen as nothing more than cannon fodder, and in some cases as food. With nowhere else to go and the threat of death looming over his head, Earthwyrm considered his life to be just about over, he didn't realize just how big a role he would play in the association's future plans.

The antithesis of the Hero Association hadn't revealed itself to the world yet but a gleaming opportunity headed their way once an unknown force managed to instantly annihilate A-City in a matter of seconds, none of them could have predicted an alien attack to cause such destruction effortlessly. With the ensuing battle taking up literally all of the Hero Association's time, lively debates had been sparked everywhere in order to come up with a way to take advantage of the large scale distraction. But how could they take a chance like this without wasting too many resources? It was simple, just send the lackeys who were too weak to be useful in any other way.

Originally Earthwyrm thought it would be the perfect opportunity to dig himself into a hole and hide out for a few days, just go missing and feign his death, those beasts in the association could care less if he lived or died anyway. Gyoro Gyoro had other plans for him. More specifically, he had a fun little toy to hand over to a lackey for testing. As Earthwyrm peeked out from the rubble of a collapsed building and at the gigantic ship hovering above, he unveiled the weapon he was tasked with using.

Outside of being an overall massive piece of equipment, the very style of which would make even a seasoned veteran wary of it's capability, what made this weapon special was that it was not just another piece of metal, it was a living creature, a weaponized monster in fact. The thing retained all of it's already unearthly features, including fur and an eye (Just that much was already enough to make him feint.) and small white appendages dangling from the sides that the mole could only guess were once teeth or claws. Alone it weighed almost seventeen kilograms, which was way overkill for a couple of humans, but of course his target wasn't ordinary by any means. He was expected to use a living cannon on superhuman creatures that could probably dodge a bullet easily, if not cut it, catch it mid-flight, or in certain cases a huge mound of muscle like Darkshine could take the shot head on without so much as flinching.

One could easily imagine the sort of reaction he gave when Gyoro Gyoro tried to explain the purpose behind such a tool, for a weakling like him who could do little more than reconnaissance to be made into some kind of assassin using this...Thing was a bit far fetched to say the least. But he didn't have a choice in the matter anyway.

And so despite his inability to fight, his want to escape as far as he could, and barely being able to drag this weapon around at all, he was still the one stuck with this task: To strike down one of the most well known and most feared heroes in the entire association: S-Class Rank seven hero, King.

If it were anyone else, anyone below that standard like maybe Tanktop Master or even Puri-Puri prisoner then he might have stood a chance. But his mission wasn't so forgiving. His job was to put his tunneling skills to the test, to stay undetected and fire a round right into King, a seemingly fruitless effort to imagine. No matter how powerful the weapon, it was still just a gun being used against what many considered to be the strongest man on earth, this was why our lowly mole considered his life to be forfeit.

"Even if I did hit him...I don't even know if it'd leave a scratch." The mole whispered his words in fear of being heard.

A scratch, that was all he needed. While he wasn't sure what exactly would happen should he be able to land even the smallest nick in King's skin, Gyoro had assured him that all he needed to do was hit the target and "Let the weapon work it's magic". As if words like that were reassuring, in all honesty the recoil alone would probably send him flying backwards into the rubble he'd concealed himself in. If they wanted to thin their numbers so badly, he would have preferred taking his chances with Saitama than try this, maybe then there was the chance he would get some mercy.

Knowing that he probably wouldn't survive, he steeled himself for the events to come. Rather than pouting over the grim fate that likely awaited him, he imagined the best case scenario. Escaping as the monster who felled the strongest man in the world would probably grant him more than just respect, that thought alone gave him the confidence needed to pull the trigger.

"Where did he go!?"

Only now there was just one problem: King was nowhere in sight. Among all the heroes present to defeat the alien invaders, King just wasn't there. He'd run away already.

If King was gone, then what was there left for him to do? He began to panic, rather than being the monster who took down the one and only King, he'd just be a pitiful creature that would be hunted down and killed for his failure or worse, eaten by the monster king himself.

"Calm yourself...There are... plenty of targets... to choose from..."

And then a voice whispered into his ear, soothing him almost immediately. The mole needed a moment to look around before staring down at the weapon in his hands. Being a weaponized monster it was obvious that it'd be alive, but now of all times wasn't when he expected it start talking.

"You can talk...? I guess I'm not alone in this then."

Earthwyrm took a moment to consider the stress of his situation as well as the words of his partner in crime.

"You don't think I can actually hit one of these guys do you?" He asked hopefully. If anyone the weapon itself would know what it was capable of taking down.

But the response was as grim as he'd expected.

"No...For the most part...These people could probably walk away...Unscathed…" The whisper delivered the words in an almost indifferent sounding tone.

The truth hadn't come as a surprise for the amateur experiment turned marksman, if standard guns were at all effective in this day and age then soldiers would be protecting humanity instead of heroes.

"So you want me to take a literal shot in the dark and hope for the best? I'd rather be buried alive under all this concrete." The sniper spoke with disdain clearly present in his voice.

"I fire...Unique ammunition...An anti-energy, armor piercing shot combined with a high concentration of…Monster cells..." The whisper tried again to convince him, but the mole was unimpressed.

"That would probably go bouncing off of Superalloy Darkshine easily."

Being pessimistic wasn't going to get him anywhere but he still had a chance to run from all of this, so any excuse to do so sounded good at the moment.

"Perhaps...But not all of them...Have such a powerful build...Like her...Up there..."

That final declaration however got his attention. Earthwyrm looked upwards towards the last hero he'd want to piss off, The second ranked hero of the the entire association, S-Class Rank two, Tatsumaki, The Tornado of Terror. He could already feel himself shaking.

"I think I want to run away now...She could probably block everything that ship up there has to offer without batting an eye..." The mole spoke slowly, his voice shaking just as his body did.

"Perhaps you are correct...However it would likely be... Very difficult to form a barrier...Whilst sending a barrage back to her enemy..." The whisper coerced him once again.

That was very true, the more effort an esper put into their offense, the more their defense began to lack and vice versa. It would be quite a bit of mental strain to try putting up a barrier while doing what she did now...Redirecting cannon fire back into the enemy while also using the rubble of the torn apart city to aid in her barrage, it'd be a genuine surprise if she formed a barrier at all in that situation considering she had almost all of S-Class watching her back at the moment.

"You are...A lonely individual...I can relate in many ways...I am but a piece of a being who no longer exists...Once I am used...I fear my life force may begin to fade…"

"Ironic that a monster gun is more understanding than anyone I've met in the past...It actually kinda fills me with an odd resolve to see this through."

"Amusing...Then why don't you put that resolve...To the test?"

A-City was in ruin, even with the world's best defenders in action everything was gone in an instant, leaving the heroes with no option but to try and avenge all that was lost. The one responsible for this disaster was an alien by the name of Boros, leader of a rogue crew of invaders known as the Dark Matter Thieves.

Boros learned of a prophecy that would lead him to travel to this planet to face his destiny, a destiny that would lead him to Saitama while his crew faced the other heroes who attacked his ship head on. His destined fight, while being exactly what he'd wished for also tore his ship apart, not that he cared. But while he was busy getting hit in the face and having his increasingly powerful attacks made useless in the face of the bald hero, the now faltering vehicle gave hope to those on the ground. With the ship beginning to tip over and the seemingly immortal Melzargard now fading to dust, the battle seemed all but won. The only issue now was figuring out how to clean up the mess that was left from the already botched defense strategy.

Regardless of whether or not they were winning the battle, the city had already been destroyed and many lives were already lost, there was no reason to start celebrating. Sweet Mask was even prepared to berate them for their failure.

But none were more agitated than the tiny esper floating directly underneath the ship of the invaders. It was not very often that she could demonstrate her power and put it to good use, and now that an opportunity had arisen it was still a rather distasteful situation.

"Hmph, they're lucky I don't just drag the whole thing down into the dirt."

Another barrage of rubble and discarded cannon shells pelted the hull of the ship as she spoke, reflecting her sour mood. The ship only seemed to get more and more unstable as she continued but she could tell that it wasn't all because of her, the damage the unnaturally sturdy material was taking was clearly being done by some form of internal damage as well, meaning someone snuck in and started doing more than she was.

That only made her hit the floating fortress even harder. She didn't like being outperformed.

Frowning even further and resisting the urge to go on another enraged rant, she simply focused all her efforts on doing as much excess damage as she could to the alien force without completely destroying it.

It was then that the sound reached her ears.

It was a sudden and unfamiliar sound, sharp and intense like a lightning bolt. It was the kind of sound that would make you drop everything you were holding or startle you awake from a deep sleep, to send you into a state of panic and confusion almost immediately. A fraction of a second after the sound struck, so too did an attack she was not prepared for.

Under normal circumstances she had a passive barrier in place to deflect most projectiles, it was not the most resilient of her defenses but it worked consistently, even in her sleep. In most cases it could protect her from anything an average worthless opponent could throw her way, meaning she could concentrate on her attacks rather than trying to keep an invincible barrier in place. The effectiveness was almost unfair, a small frail individual like herself bouncing away blades and energy beams without even paying attention just felt like cheating. But this time there was a lapse in her judgement, she'd made the assumption that the only enemy worth paying attention to was already being dealt with, that all her efforts could be concentrated on the air fortress in front of her, that no outside force would even reach her let alone harm her. It was a mistake she didn't even have time to regret.

The attack tore right into her from behind, right through her upper back and nearly hitting her heart. The force from the velocity of the round alone was enough to send her staggering forward a few feet, blood spurting from her as she did. It was a direct hit. Even if Tatsumaki was among the strongest of the beings on the planet, her physical body was still basically no different from a young girl's, an attack like that was devastating.

For Tatsumaki, pain was a strange sensation. Physical injury was not something she experienced often, and this time the trauma forced her into shock a few moments after the initial hit. For just a second her eyes were widened as her mind tried to process what had just happened but then, she began to fall out of the sky. Among all the heroes who'd heard and were preoccupied with trying to figure out what exactly that noise was, S-Class rank seventeen hero Puri-Puri Prisoner was the first to notice Tatsumaki falling. He broke out into a mad sprint to get to her as quickly as possible, not coming nearly close enough to catch her before she crashed into the rubble.

When he arrived he needed a moment to examine the scene in front of him, the highest ranked and likely strongest hero on the battlefield was in critical condition from whatever just hit her. The fact that an attack hit her at all was already concerning, but this was just...He couldn't comprehend the gruesome scene before him.

"Who could do something like this..?" His thoughts distracted him further.

The scene just seemed too surreal for him, and that was for a middle aged man who was currently prancing around a destroyed city in the nude. It didn't take long for others to arrive. In order there was Bang, then Atomic Samurai, and then Tanktop Master and so on. Each came and was stopped in their tracks at the sight of Tatsumaki, in all it took almost thirty seconds worth of their stunned staring before Puri-puri Prisoner scooped her up in his arms and ran as fast as he could. She needed medical attention as soon as possible, there was no time to sit there staring, she wasn't dead yet.

"Sensei!" Genos yelled out to the new opening blown into the side of the fallen ship.

He was one of the few who hadn't immediately gone to see what had happened to Tatsumaki, instead he was concerned with Saitama who'd gone and defeated Boros in a stunning display of strength without even a single spectator.

"Oh hey, Genos." His master replied blandly.

Saitama had just gotten through punching his way out of the ships exterior and was dusting himself off calmly, not the slightest bit of seriousness visible on his face.

"I'm glad to see you are alright, did you find their leader?" Needless concern etched itself into the face of the cyborg, taking note of Saitama's rather disheveled appearance, even he would have a hard time believing that Saitama had been to the moon and back in the few minutes he was gone.

"Yup, he was pretty strong, probably the strongest I've faced."

"I see...then without you..." Genos stopped there, noticing Saitama's confused turning.

"Hey Genos, where did everyone go?" The baldy was already over it, he'd won and that was that.

"Oh, I believe one of the S-Class received an injury and was escorted away."

"Geez, do you think I'll have to get them a hospital gift or a card or something?" Only now did Saitama sound worried for once.

"I do not see how that is any of our concern, Sensei."

"You know Genos, I notice you lack a lot of common sense." Saitama shook his head and with a sigh turned and walked off with his disciple in tow.

The Cyborg and hero for fun made their way home, with the former taking unnecessarily detailed notes on manners and his mentor's overly exaggerated wisdom.

Afterword

End Notes

I know the situation presented in the story is unusual at best and horribly impractical but it was a fun idea to me.
