A/N: When the time comes, play the music. You know you want to~


Geryuganshoop was flying through the halls, sweat dripping down her face as she sent her telepathy to every living organism on the ship.

"EVERYONE! GET TO THE ESCAPE PODS! LADY BOROS IS ABOUT TO UNLEASH HER FULL POWER AGAINST THE INTRUDER! RUN FOR IT!" she warned. She could hear the horrid responses as the various aliens all began to scramble to escape, hoping to not get killed from Boros fighting.

"I just hope the ship can still function after Lady Boros destroys that intruder." she muttered to herself.


Boros launched herself at Saitama, fist raised to strike the baldy. Her attack was blocked when he simply raised his forearm, sending a shock wave throughout the large room. She grinned as she began a merciless onslaught of high-speed punches, all of which were blocked by Saitama's forearm. She finished her attack by reeling and slamming him with a powerful punch that sent him flying back. The hero stayed on his feet when he landed before running backwards away from Boros, who ran after him shortly after she punched him.

A purple aura surrounded her as she began to attack again, each punch blocked by Saitama, but sending him flying around the room each time. Both combatants were launched into opposite sides of the room from the last encounter, but quickly jumped at each other for a head on collision. Saitama, deciding to take action, raised his hand for a punch just before they struck. They landed on their feet, but Boros found that she was now missing her right arm.

"Even though my true power's been unleashed on you, somehow, you're still able to keep up!" she exclaimed as she turned towards Saitama, who turned to face her as well.

"Yep." he answered as he raised the smoking fist he just struck her with. "You're tough. Cool."


'I should've brought one of my 'Battle Ready' tank-tops.' thought Tank-Top Master as he wandered through the ruins of City-A.

'Putting City-A back together may be impossible. I'll think about that later. Right now, I need to focus on the battle. She may be up there at Rank-2 or whatever, but I won't sit back and leave it all to one little girl.' he thought, fists clenched and ready to act. 'I happen to have my own ways of fighting enemies in the air. Like this!' With that, he grabbed a giant hunk of debris far larger than him and hoisted it over his head. He roared as he put his all into throwing it at the ship, landing a direct hit.

"HEY! What do you think you're doing?!"

Tank-Top Master looked around in confusion before yelping in shock when he realized that he was now standing on one of many massive hunks of broken building floating in the air, a green aura surrounding them.

"This area's got some nice rubble to play with. Get out of my way and let me do so." Tornado ordered.

'She...She's using her psychic power?!' he thought as he fell towards to the ground. "I give up!" he lamented just before Tornado began her attack.

Building after broken building smashed into the bottom of the ship, causing explosions over the entire underside.


The aliens were becoming frantic as they tried their best to evacuate the ship. If they weren't trampling over each other to get out, they were trying to pull others out of the escape pods to make room for themselves. It also didn't help that the ship was now under constant attack, with some escape pod exits being destroyed as a result.

"MOVE IT!"

"DON'T PUSH ME!"

"I DON'T WANNA DIE!"

"LADY BOROS IS GONNA GO ALL OUT!"

"THIS PLANET'S CRAZY! WHAT'S WITH ALL THESE STRONG CREATURES?!"

"I just wanna go home!"

The aliens kept with their mad scramble before they noticed that the ship suddenly stopped shaking.

"Quit screwing around and get into those escape pods!" Geryuganshoop ordered. They all turned to see her holding her hands out, a look of concentration on her face. "I'm stopping their attacks from reaching the ship! Take this chance and evacuate!"

She earned a round of joyous thank yous from the crew before they started to get into the escape pods.


Tatsumaki blinked in confusion as she halted her next wave of debris due to noticing that the rubble had stopped reaching the alien ship. She furrowed her eyebrows when she felt a psychic source coming from inside the ship.

"So they have an Esper on board, huh?" she droned before smirking. "Guess I'll get to fight more than just an overgrown toy."


Geryuganshoop sighed in relief when she no longer felt something try to hit the ship before grunting in surprise when she felt a force begin to pull at her.

'What's going on?! Something's got me?!' she thought before she started to resist.


Tornado chuckled when she felt whatever was up there start resisting.

"Well, what do you know. They actually have some fight in them." she said before clenching her fist and swifting yanking at the air.


Geryuganshoop felt the pull increase, making her groan and pant as she fought back.

"Alright!" she grunted as she looked in the direction she felt the source coming from. "You wanna fight?! Fine!"

With that, she erected a barrier around herself before letting herself get pulled through the ship.

"Let's fight!"


Tatsumaki felt the resistance stop, allowing her to pull whatever it was right out of the bottom of the ship before bringing Geryuganshoop before her.

"Hmph. A psychic octopus is the one stopping my attack?" Tatsumaki scoffed.

"I am not this thing you call an octopus, you tiny earthling!" Geryuganshoop snapped. She then found herself struggling to keep her barrier up when the pressure increased.

"What did you say to me?!" Tatsumaki growled, a vein appearing on her forehead as she clenched her fingers, her power flaring as she attempted to crush Geryuganshoop into pulp.

"No you don't!" Geryuganshoop yelled as she strengthened her barrier before leveling a glare at Tatsumaki. "That other human may have been stronger than me, but I will not be bested by an earthling child!"

"Child, am I?" Tatsumaki asked, an almost slasher smile coming to her lips as the wind kicked up around the two.


Melzargard was fighting Atomic Samurai one-on-one, a grin on his face as he attempted to skewer the human with his arm morphed into a spear. Atomic Samurai merely slashed away at it every time it came near him, the pieces floating back to Melzargard each time. It then sprouted at least a dozen spikes from his the slashed arm before launching it, but Atomic Samurai danced around the attack while slashing each spike off before jumping away, leaving Melzargard to laugh at the human.

"Bastard! You sure are making things interesting!" AS growled, his bloodshot glare focused on Melzargard.

"OH CRAP!" Metal Bat suddenly shouted when he noticed what looked like smaller bullets begin to rain from the ship.

"More attacks?!" Puri-Puri Prisoner yelled in shock before bracing himself for the explosion. He nearly lost his footing as one of the bullets landed close-by, causing him and the others to steady themselves before looking at it. "A dud?" he muttered before taking a better look at it. "Is that a hatch on that projectile?"

They got on guard again when it released a hissing sound before opening, revealing around a dozen alien creatures.

"Reinforcements, huh?" Metal Bat asked while tightening his grip on his weapon. "I'll break their heads open too!" That got the aliens inside the pod to start screaming for their lives, begging for mercy while some threw their hands up in surrender.

"LEAVE THEM ALONE!" Melzargard roared as he shifted his attention towards Metal Bat.

"Hey. You forget about me?"

Melzargard didn't have time to register the voice before he felt over 100 slashes run through his body in the span of a second.

"ATOMIC SLASH!" Atomic Samurai shouted before Melzargard's body split into hundreds of tiny pieces.

"Insolence!" Melzargard's voice growled as his body began to regenerate. "SUCH COMPLETE INSOLENCE!"

The heroes prepared themselves before a voice stopped them from attacking.

"You move that heart-marble thing around inside your body to hide its location, but your regeneration process always begins with your head. Therefore, at the center of that must lie...YOUR HEART!"

Melzargard was stunned to the point that his regeneration ceased just after forming the top part of his head. His eyes turned to see Bang standing behind him, his scarred body on display from his lack of a shirt, and his arm piercing his head. And resting between the old hero's fingers was the final marble.

"How...are you alive?!" Melzargard gasped in shock.

"After seeing it happen so many times, even a monkey could figure it out." Bang continued, his fingers lighting tapping the orb. "See? Checkmate!"

"NOOOOOOOOOOOOOOOOOO!"

CRACK!

With the final marble in pieces, Melzargard's body melted away, signalling his demise.

"Silverfang!" Iaian exclaimed in relief, glad that he wasn't dead.

"All I needed was one more swing. Keep your hands to yourself and let me finish what I start, Silverfang." Atomic Samurai said with a smile.

"My goodness. I really need to do more full body workouts." Silverfang groaned as he patted his back.

"We got all the heads. That was the last one! Victory is ours!" PPP stated in joy.

"Yeah, but we still got that big ass ship up there." Metal Bat pointed out before glaring at the stunned aliens. "And let's not forget these freaks."

"Wait! We surrender! We don't wanna fight!" one of them yelled in a panic.

"You think that'll fix this city? Or bring back all the lives you bitches killed?" Metal Bat growled.

"Blame him! He couldn't keep his subordinate under control!" one of the aliens yelled while pointing at the gunner.

"Yeah! Yeah! And the little dumbass got trigger happy before we could make contact!"

"Take him and leave us!"

"HEY!" the gunner yelled at the sudden betrayal of the crew before suddenly coming face-to-face with a group of very powerful and very pissed heroes.

"Well?" was all Atomic Samurai said as he glared at them.

"L-Look, it's not all my fault! The little shit w-wanted to impress our leader and thought that just blasting w-would do it! I got an eye ripped off, and they've been punished for it and...and...I JUST WANNA GO HOME! MOMMA!" the gunner cried, blubbering like a child.

"Dude, quit being a baby!" Metal Bat grumbled before he and everyone there had to try and keep themselves from falling over.

"What now?!" Iaian yelled in panic as massive pieces of debris began to float once again.

"Guess Tornado's starting to get serious herself." Atomic Samurai mused as they all turned to the skies.


Twin Tail, Heavy Kong, and Shadow Ring were still searching for survivors before they noticed the debris around them lift into the air and the wind picking up speed.

"Looks like Tornado's really getting into her fight!" Shadow Ring shouted over the wind as she and the other two Class-A heroes looked up into the air. They could see the debris crumbling into fist-sized pieces before swirling around Geryuganshoop at an alarming rate, then thrown at high speeds towards Tatsumaki, who kept them from hitting her with her psychic barrier.

"Let's just hope she keeps the fight up there and not down here." Heavy Kong yelled.


Genos and Child Emperor watched the fight between the two Espers taking place in the air, the sight quite something to behold.

'So this is Tornado's power? Is she going all out, or holding back?' thought Genos before looking down to see Drive Knight walking by.

"I'll be taking my leave now." he stated, one of the many aliens who'd dropped in the escape pods held in his grasp. "I wish to study some of these specimens for research.

"Help...me!" it cried out in a tiny voice, tears in it's eyes.

"Things here seem to be under control." Drive Knight continued.

"Sure. Go ahead. Some of the other heroes have already left." Child Emperor told him in a bored tone before looking back up at Tornado.

"Before I go. Genos, have you got a second? There's something I wish to tell you." he said as he approached the other cyborg.

'Drive Knight. Class-S, Rank-9. This is a first.' Genos thought as Drive Knight stopped beside him.

"Listen. Metal Knight is actually your enemy." he whispered to Genos, making his eyes widen a fraction. "Be careful."

"What do you mean?" Genos asked as he turned to the retreating form of Drive Knight.

"You will know soon enough. But for now, stay away from him." Drive Knight warned without looking back, his specimen in hand, leaving Genos to ponder his words.

Mumen Rider was riding his bicycle alongside a Hero Association transport vehicle being driven by Lightning Max, with Stinger riding on top.

"I really hope Tornado doesn't use more power than this!" Lightning Max called out.

"I wouldn't worry! She can't possibly do any more harm to this city!" Stinger yelled back before looking to Mumen Rider. "You doing okay there?"

"Yeah! I'm fine!" called back the cycling hero. "Are you sure that the women inside was the last reported survivor?"

"That's what we were told! The other heroes have already gotten everyone else!" Stinger answered before looking back up at the ship. "Now all that's left is taking down those bastards!"


Boros roared as she let loose a furious barrage of high-speed punches with her remaining arm, all of which was calmly blocked by a calm Saitama as the two battled inside the throne room. Each strike send out shock waves, the sound akin to thunderclaps echoing inside the room as the two battled inside the room. Though if you looked closely at their little dance of death, you'd see that Saitama was merely defending himself while Boros did all the attacking.

The two collided multiple times in mid-air before Saitama was launched away by one of Boros's kicks, followed by a punch that sent him crashing through pillar after pillar inside the room. He finally stopped and was embedded into the seventh pillar, his cape slowly starting to tear.

Boros wasn't letting up as she quickly lunged at him, deliver a massive dropkick, shattering the pillar with explosive force. She chased after him as he retreated up the pillar, the energy and speed coming from her so intense that it left a trail of heated metal behind her as she sent out more kicks and punches. She didn't let up even as they plowed through the metal ceiling and up onto the top of the ship. The small piece of metal surrounding them dented outward as they had their fight before bursting, allowing both fighters to land on the top of the ship.

"Impressive. As I thought, you are strong! Of the myriad beings I've face so far, only you have survived for this long!" she complimented with a smile, her power surging around her.

Saitama merely watched as she readied her next attack, his face still expressionless.

"Now to release the destructive power within me!" she roared as a beam shot out of her and right towards him. "Any creature hit by it would find even their bones vaporized!"

Saitama merely stood there and took the attack head-on, letting the blast hit him and demolish the area around him. A moment later and he stood up amongst the inferno surrounding him, wondering what she'd do next.

"BEHIND YOU!"

"Huh?" was all he said before he felt her backhand him on the side of his head, causing his head to tilt slightly. The power from the punch alone sent out a shock wave that not only snuffed out the fires around them, it cooled the heated metal and blasted the smoke from the previous attack away.

"You were definitely my greatest opponent." she praised with a wide grin. "But...the outcome of this battle is clear."

"My species won the battle for survival against the harsh environment of our homeworld. We possess the ultimate in regenerative abilities. I, in particular, have the god-like traits of self-healing, physical prowess, and latent energy beyond your conception. A would that would be fatal for you heals on me in mere moments." The stump that was her right arm began to twitch, a disturbing organic sound eminating from it. "By focusing my energy on my destroyed arm, I can exponentially speed up the healing process!"

In a flash, white flesh sprouted out and formed a new arm, which slowly changed into her skin tone.

"Good as new." she said as she showed her arm off to Saitama, who had leaned his head back upright. "You, on the other hand, will only get more injured, all while your stamina gradually decreases-"

"Shut up."

Boros blinked at Saitama's interruption, the hero giving her a bored look.

"Blah, Blah, Blah. You're boring me out of my mind." Saitama groaned. "Are you finished?"

Boros just stared at Saitama, as if unable to believe that he sounded so...bored. As if none of her attacks had done anything to him. Her hands trembled before gripping into fists.

"NOT YET!" she roared as she hunched over, her energy flaring once more. Saitama just watched as a dome surrounded her as her body began to change again. Her skin turned white as the markings turned back to their original blue color. Her hair grew longer, reaching all the way down her back. Her muscles slightly grew, along with her breasts, hips, thighs, and butt.

"METEORIC BURST!" she bellowed in a crouched position.

She then lunged at Saitama with speed so great that it actually surprised the bald hero right before she slammed her fist into his face. The impact was so powerful, it was almost as if he was being blasted by a bomb. A long streak of melted metal appeared behind him for a moment, a lot of which reached into the ship and vaporized any unlucky souls still trying to get out.

Saitama found himself flying back at incredible speeds before Boros was upon him again, moving with such speed that it was almost as if an army of her had appeared and were taking turns pummeling the baldy with kicks, punches, elbow strikes, knee strikes, and so much more.

Both of them zoomed past the top of the ship, the wind blasting much of the protruding metal structure to pieces before friction melt turned much of it into molten slag.

"The energy shunted from my body transforms into a propelling force!" she began as she continued to brutalize Saitama, while at the same time causing massive damage to her ship with each passing second.

"Elevating speed and power to a level beyond the limitations!" she continued as she grabbed him by the cape and threw him, only to zip over and intercept him and slamming him into another direction with both hands. "OF LIVING FLESH!"

She followed after him before jumping and striking with her knee, the attack so powerful that it sent waves of energy across a lot of the top of her ship. Saitama was bent over her knee for a moment before she kicked him skyward, sending out another shock wave as Saitama flew before he finally stopped. The bald hero merely stayed in the crater he was in as he noticed that things suddenly got...quiet.

'Wow.' he thought as he looked up at the bright blue marble that was Earth. 'Never had anyone hit me to a moon before.' He held his nose shut when he remembered that there was no air in space before standing up. 'Gravity on the moon's a lot less than it I thought I heard it was.' He then picked up a moon rock the size of a baseball before tossing it up and down a few times, watching it slowly float back into his hand. 'Right. Guess I'll need about that much strength to get back.' With a nod, he tossed the rock over his shoulder, crouched down, and then launched himself off the moon with enough force to create a crater that could almost be seen from Earth with the naked eye.


Rubble flew and stones ignited from friction as two forces of nature clashed for supremacy. For once in her life, Tastumaki had to apply effort as she had to weather the assault of this alien freak. Geryuganshoop grew slightly tired from all the force she put to crush this errant child. She had to get back to the ship from what she felt Lady Boros enter her powered state. The longer she was in that state, the more her lifespan would be whittled away.

"I'll admit, your abilities are impressive." Tatsumaki said with a smile as she kept attacking and deflecting. "I'll have to try and see about learning how to remove the friction from my own attacks in the future."

"Urgh!...Don't think that...you've won!" Geryuganshoop groaned as she resisted the urge to rub her aching head. Never in her life has she had to use this much power at one time, and on a single enemy. But from her encounter with Saitama, defending her crew, and her little battle with Tatsumaki, the pain was slowly rising from a nasty headache into a splitting migraine. But she knew that if she dropped her barrier, or ceased her attack, then the earth girl would finish her off without hesitation and crush her into dust.

'I've got no choice.' she thought, a yellow aura surrounding her. 'This may kill me too, but if pushing myself that far means I can take down this creature, then so be it! At least she won't annoy Lady Boros when she comes down to-'

Without warning, an almighty crash rang throughout the battlefield, causing the two espers to stop their fight for a moment and look up, along with everyone else on the ground.

"IT'S TILTING!" Metal Bat shouted.

"Was that you, Tornado?!" Darkshine asked while the rest of the aliens started to panic.

"What's that creature doing up there?!"

"Is he trying to bring the ship down?!"

"What'd Lady Boros doing?!"

"Maybe she did that!"

The other heroes just wondered who they were talking about as the aliens ranted off questions.

"It can't be."

Tatsumaki looked at Geryuganshoop to see her staring up at the ship, her eyes wide and full of disbelief, no longer focusing on the fight.

"Lady Boros will win like she always has...right?" she asked herself with a strained smile. "There's no way that earthling could've bested her...right?!"

'Boros? Is that the name of their boss?' thought the smaller esper before gazing up at the ship as well. 'And who's this person that's fighting them? Did someone sneak up there? But who?'


Boros just stared at the smoking crater that appeared on her ship, her eye wide and unblinking as Saitama slowly made his way out into the open.

"Cool." Saitama said with a smile as he looked down at Boros. "I made it back."

Boros stood there for another moment before glaring at him, her eye becoming bloodshot as she began walking towards him.

'This infuriating man...MAKES ME WANT TO GO ALL OUT!' she thought before roaring and rushing him, her form a blur as she sped past him and struck him from all angles with more ferocity than before.

Deciding to finally retaliate, Saitama met her fist with his, causing another shock wave to ring out before crumpling her arm and sending her flying backwards. She did a back flip in mid-air before planting her feet into the ship, leaving two metallic trenches before finally stopping and holding her deformed arm.

"HAHAHA!" she laughed as her arm repaired itself. "THAT'S THE WAY, SAITAMA! YOU'RE DEFINITELY WORTH THE EFFORT!"

"Consecutive Normal Punches!" Saitama said as his fist flew so fast that it was nothing but a red whirlwind swirling around her. She didn't have time to react before her body was blasted into a gory mess while her ship suffered more damage from a few of Saitama's punches. Her main eye twitched before widening and turning black. It gazed down at Saitama as what looked like a blue flame flared up in her pupil a moment before her body reformed itself.

"I...WILL...DEFEAT YOU!" she bellowed as she hung in the air, her body glowing and sparking with more power than ever before. "ALL OF MY ENERGY WILL BE RELEASED! BLAST YOU, AND THIS PLANET, STRAIGHT TO HELL!"

Despite how furious she was, it could not quell the feeling that had come to her. The feeling that she had not felt in such a long time, no matter how many battles she'd fought in all her life.

The feeling...

BA-BUMP!

Of adrenaline surging excitement!

"COLLAPSING STAR, ROARING CANNON!"

A colossal ray of pure power was shot from Boros and heading straight for Saitama, ready to finish him and the earth off once and for all. Saitama, his expression serious, glared at the approaching beam.

"In that case, I'll use my own final move." he declared, his fist tightening. "Killer Move, Serious Series: Serious Punch!"

With effort he's never needed to use before, Saitama thrust his fist towards her. The sound barrier broke as an unstoppable force utterly crushed the opposing force, soared across the skies, and parted the clouds. Two identical paths going one way, and a massive one splitting the clouds halfway across the planet.

"...I...lost?" Boros asked in a quiet voice, her mangled and barely recognizable body lying on the roof of the ship a good distance away from Saitama. Her skin tone was now a sickly, grayish black, her lower half and arms looked to be melted into goo, and her main eye and secondary eyes were both black and blank.

"You're still conscious?" Saitama asked with a small smile as he looked at her over his shoulder. "You really are strong. For real."

"The prophecy held true. The battle was...a hard, fought one." Boros wheezed out.

"Yeah. Sure was." Saitama said, what was left of his cape flowing in the wind as he faced away from her, missing the small smile she gave him.

"Hehehe...liar. Even at the end, you still weren't even trying." she stated. "It wasn't even a battle. I stood no chance against you. And yet..."

A tear slowly trickled down her eye, her smile becoming serene as everything started to go black for her.

"And yet...I had fun. I honestly...want to fight you again...Saitama." she said as the ship around them began to crumble.

"You know." Saitama began as he walked away. "That'd be nice."


And that's it for the fight. Stay tuned for the aftermath.
