Bowser roars as he runs full speed at Izuku, throwing a strong punch to the young Hero's face. Izuku uses his only functioning arm to deflect Bowser's punch to the right, then throws a strong kick to Bowser's chin that makes the large turtle's head snap back.

Bowser snarls as he swings his tail and slams it against Izuku's side, hitting his right arm and breaking it even more. But Izuku wasn't going to give him any more satisfaction by letting the Koopa King hear his screams.

He held back his scream and struck Bowser in the face with a strong punch, this one sending him crashing backwards a bit.

Izuku then leaps at Bowser and hits him with a strong kick that knocks his head back, sending him falling onto his shell. Bowser growls as he gets to his feet and throws another strong punch at Izuku.

Black Whip surrounds the entirety of Izuku's right arm and, in spite of it being severely broken, his arm moves up and blocks Bowser's punch. Izuku strains and screams as he feels his bones breaking more and more, but refuses to back down.

"You stubborn bastard…" Bowser growls. "No matter how much I beat you down, you don't stay down! Well then… I guess I'll just have to break EVERY. SINGLE. PART OF YOU!"

Bowser keeps pushing his fist forward, increasing the strain and suffering Izuku's arm is going through. Izuku coughed up blood as his strength began to falter. If this kept up, Izuku's entire arm would practically be obliterated… as well as the rest of him.

"Izuku!"

Through the chaos, Izuku's eyes widened as he heard the voice of the seventh user of One for All speaking through his head.

"When you think you're at your limit, remember!"

Izuku's shocked expression turns back to determination. "It doesn't matter… how much you… beat me to a pulp…" Izuku says through gritted teeth, his hair standing up as his eyes flare the same green as the lightning crackling around him. "So long… as this world is under threat by you… and any other threat that rears their ugly head…"

Izuku stomps his foot and stands his ground, stopping Bowser from pushing back anymore.

"I won't…"

"You seriously think you can keep going like this?!" Bowser growls.

"I won't…!" Izuku's left fist crackles with all of the One for All power he can use.

"Don't be ridiculous!"

That's when Black Whip deactivates as Bowser's fist keeps pushing forward… but Izuku side-steps to the left, his left fist reeled back, while his right arm takes the full assault of Bowser's punch.

"... I WON'T DIE TO THE LIKES OF YOU!" Izuku screams as he swings his fist into Bowser's face, hitting him with all his might as the Koopa King is left dazed and reeling from the punch, a few teeth even flying out.

The shockwave of the punch pushes everyone back. "At the last moment, he transferred all the power to his left fist…!" Cranky thinks to himself. "He used his right arm as bait! But…!" His eyes narrowed as he knew this wouldn't be nearly enough to keep Bowser down. And he basically made his right arm even more useless than it already was now.

"BACK OFF!" a female's voice screams from above, making everyone look up and see a female Kong about the same size as Diddy Kong. She had light brown fur, green eyes, blonde hair in a long ponytail, and wore a pink tank top and beret. Her ponytail was spinning like a helicopter, allowing her to fly through the air.

There was something bright held in her hands, and everyone's eyes practically bulged out when they realized she was holding the Super Star that Bowser had stolen! And sure enough, she was being chased by some of Bowser's minions, specifically the ones that could fly!

"Dixie!" Tiny and Diddy Kong shouted in worry, seeing how outmatched the Kong girl was. Dixie could see it too, and knew that her plan was gonna have to be kicked into high gear.

"Izuku!" Dixie Kong shouted as she flew past Bowser's airborne troops, barely dodging their dives and spear thrust attacks with her heavy load. Both of the fighters' attention turned to her. "Catch!", with all her might, she heaved the Star towards the badly wounded, heavily panting Izuku, much to Bowser's horror. Since when did those horrid Kongs break into his castle?!

"NO! THAT'S MINE!" Bowser yelled in rage as he made a mad, and quite frightening, dash towards the Star falling towards Izuku.

"Izuku!" Peach shouts as she kicks a Koopa into its shell. "Get the Star!" she screams as she kicks the shell into Bowser's face, knocking him off course for a second.

The Star hits the ground and bounces right over the green haired Hero. Izuku, despite his many bruises and burns, possible broken ribs, and mangled right arm, makes as mad of a dash as he can for the Star. Each step felt like a thousand burning needles, but he had to push through the pain. If he didn't get the Star, Bowser would for sure kill him this time.

Bowser suddenly gets halted and falls to his stomach as something grabs his tail. He glares back and sees both Donkey Kong and Funky Kong holding him by the tail with all their Kong might.

"Not another step, sicko!" Donkey Kong growls through gritted teeth as Bowser tries to pull through and break out of the Kongs' powerful grip. The Koopa King manages to get a few steps in with strained growls escaping his mouth, each one sinking into the ground from how much strength he was putting into his damaged body.

"GET OFF ME!" Bowser screamed as he, with a massive display of power, spun around harshly and threw both Donkey Kong and Funky Kong right off his tail, the screaming Kongs crashing through a few mushroom houses. He turns around and notices that Izuku was almost to the Star, but the pain from his many injuries took its toll and he falls over with a pained grunt, now briefly stunned. Angered by the fact that this weakling was closer to his power source than he was, the Koopa King finally decides to end his enemy's game and unleashes a massive blast of fire at the fallen hero.

The heat of Bowser's raging fire approaches Izuku at an alarming speed as Izuku looks back in sheer terror. This was it. There was nothing he could do. This was for sure the moment he was going to die.

... No... not like this!

In a last ditch effort, Izuku turned back to the Star with his mouth open. If his limbs were done for, then he'd just have to get creative! "Black Whip: Froppy Style!", Izuku mentally screams as a black tendril suddenly extends out of his mouth like Tsu's tongue, quickly wrapping around the Star. With all his might, he pulls the Star towards him just as the flames reach him.

From afar, the flames strike where Izuku stood and unleashes in a fiery explosion that was noticeable to everyone in the battlefield.

"IZUKU!" Toadette screamed out in terror for everyone to hear. Toad tried to erase what his brain just compromised as looks of sheer horror and disbelief were on most of the Kong army's faces, especially on the recovering Donkey Kong's.

"No...!" Peach shouted with complete horror in her eyes as Bowser softly cackled at the cruel deed he had done. "No… no, not for real this time… please!"

As Bowser stomps towards the expected burning remains of Izuku, a black tendril suddenly flies out of the smoke towards Bowser. The Koopa King, in sheer surprise, dodges out of the way, only for the tendril to come back around and wrap around his arm. Bowser notices that the tendril, which normally has a green glow around it, instead has an ever-changing color glow.

The realization of what this meant hit Bowser as his eyes widened in dread, but just as he turned back towards the smoke...

"SMASH!" Izuku screamed as he slammed his fist into Bowser's face, sending the Koopa King crashing back in a heavy cloud of dust as the ground cracked underneath him and the amplified Black Whip released him. Bowser sat up, growling in rage and pain, only for dread and horror to fill his eyes as he saw Izuku.

His hair was standing up and waving like a raging inferno. His eyes were filled with a burning hatred as they crackled with multicolored lightning, the same lightning currently crackling around Izuku's entire body as a rainbow glowing aura surrounded his entire body. His body looked completely restored to its prime, with no visible damage seen aside from his torn Hero Costume. Even his mangled and limp right arm was restored entirely, like it was never broken.

"BOWSER... THIS. ENDS. NOW!" Izuku's voice echoed with such power as he punched a fist into an open hand, which created a shockwave that was felt by everyone in the area. Bowser, finally fed up that this shrimp just wouldn't stay dead, gets up, points at Izuku, and bellows out to his whole army:

"RIP HIM TO SHREDS!"

Bowser's entire army, including the Koopalings and Bowser Jr., all rush at Izuku, completely ignoring the Kongs, Toad, Toadette, and two princesses. Izuku, glaring daggers at the whole army, bolts full speed at them. From just the shockwave of Izuku running past them, a third of the army was sent flying.

Morton and Roy try to hit Izuku with their spinning shells, but Izuku not only dodges them, but he tightly constricts them both with Black Whip, effectively trapping them in their own shells. Then, looking at the rest of the charging army, he proceeds to swing Roy and Morton with Black Whip like a pair of flails, crushing the weaker minions and even injuring the Koopalings like he did on Rainbow Road.

Bowser Jr. roars as he shoots his own fireballs at Izuku, but Izuku just glares at the little Koopaling and, after tossing Roy and Morton into the ground hard enough for craters to form, walks through the fireballs as they hit him, not fazing him in the slightest as Junior gets more and more desperate.

Finally, Izuku raises his leg and slams it into Junior's head with a mighty smash, embedding the heir deep into a Bowser Jr.-sized crater. Iggy tries to attack with a magical swing of a Chain Chomp, but the metallic enemy simply shatters against Izuku's invincible body. Stomping the ground, the pieces go flying and Izuku kicks them all at the army, knocking a quarter of the soldiers and Iggy senseless.

Wendy launches a flurry of rings at Izuku in hopes that they restrict his limbs, but Izuku catches all the rings in one hand, and without even trying, chucks the rings back to their sender, as the rings tightly constrict around Wendy and leave her helpless. Izuku then kicks her in the side, sending her crashing into the charging Lemmy, sending them both crashing into an already destroyed mushroom house.

Larry runs into the fray and starts throwing a bunch of Bob-Ombs, but Izuku uses Black Whip to catch all of them and return them to their sender. Alarmed, Larry retracts into his shell as the Bob-Ombs crash around him and explode, but the force was too powerful and sent him crashing into a small pond. Finally, the last of the Koopalings, Ludwig, uses his magic to conjure up a large number of holograms of himself that surround Izuku and prepare to blast him with a bunch of magic spells. Izuku smirks as he suddenly disappears, then blitzes around at breakneck speeds, obliterating the holograms and stopping in front of a shocked Ludwig before nailing a double hammer punch right on top of his head, the force cracking the ground just under them. Ludwig just stood there, dazed for a moment before dropping to the ground, out cold.

In a puff of smoke behind Izuku, King Boo appeared to attack, haunt or even try to possess him. If he could either kill, scare or take him over, Bowser's forces would then be unstoppable. But then Izuku turned around to face King Boo… and for the first time in his afterlife, the king of ghosts felt fear wash over his phantasmal body.

The lightning crackling around Izuku was causing shadows to cast over his eyes, but the look in Izuku's eyes was one of pure malice and hatred, peering even through the shadows as the young Hero then spoke in a menacing tone that would have scared the shit out of All for One as he says:

"And what do you think YOU'RE trying to do?"

It was like King Boo was looking into the face of a demon.

A face full of extreme terror, King Boo let out a meekly squeak before slowly phasing into the ground.

"Wuss." Izuku scoffed.

More of the army started to rush into the fray with battle cries. Kamek flies in between a bunch of Paratroopas the Koopa General was leading and draws out his wand before firing out a barrage of magic flames at Izuku, but the hero simply uses a bunch of Black Whip tendrils to swat them away, one of them lighting the fuse on King Bob-Omb's head.

King Bob-Omb frantically tries to put his fuse out, but Izuku wraps Black Whip around him and starts spinning around at high speeds. The heavy king of bombs' body slammed into the charging Paratroopas and sent them crashing into ground with their shells cracked. With a shout of effort, Izuku chucks King Bob-Omb into Bowser's parked floating fortress, crumbling the wall he crashed into. A few seconds later…

"Ka-boom." Izuku says with a smirk.

… a massive explosion burst from inside the fortress and destroyed it entirely, sending burning rubble and debris flying everywhere across the battlefield. Everyone starts to run away to safer spots from the falling fiery wrecking. Some of Bowser's troops weren't so lucky and got crushed by some, while some knocked some of the airborne ones and Kamek right out of the sky.

The Koopa King looks on in absolute shock and horror as what his proud flying battalion used to be, now reduced to nothing more than a massive pile of rubble and scrap as debris crashes all around him. He turns to the slowly approaching Izuku seemingly emerging from the flames, his rage now reaching levels he never thought were even possible.

"One army down..." Izuku started as Bowser's teeth started to gnash in fury. "...and just the king to go."

"You… Little… BASTARD!" Bowser roars as raging embers of flames emit from his mouth, his rage reaching its all time high. "FIRST YOU RUIN MY MARRIAGE TO PEACHES, THEN YOU INJURE MY CHILDREN, AND NOW YOU'VE DESTROYED MY CASTLE! YOU HAVE GOTTEN ON MY NERVES FOR THE LAST TIME!"

Izuku's response, however, was a scoff. "Oh big deal, man-child. Jeez, you make Shigaraki seem mature."

Bowser screams in absolute fury and barrels towards Izuku, readying a claw, but skids back when Izuku lands a knee to his face. The tyrant then quickly leaps forward in an attempt to crush him with a double fist, but Izuku blitzes out of the way attack, speeds onto Bowser's shell and throws him on the ground for a juggle effect, in which he then rushes in front and nails a powerful kick that sends Bowser embedded into a destroyed mushroom house.

As Bowser gets to his feet, Izuku was suddenly right in front of him, the super-charged One for All coursing through his left fist, as he then slammed that fist into Bowser's stomach, making him hunch over as a shockwave fires out from his back, even cracking his shell. He grits his teeth and grabs onto Izuku's arm, holding him in place.

"You may… be using the Super Star's power… but it's only temporary…!" he says as he grins, trying to ignore the pain. "All I have to do… is wait out the time…!" But that's when Bowser sees the One for All energy disappear from Izuku's left fist.

"A few seconds… is all I need!" Izuku says as he reels his previously mangled right arm back.

"Wha… What are you doing?!" Bowser demanded, suddenly having a bad feeling about what Izuku was about to do.

"Something that's never been seen in this world!" Izuku said with a confident grin as he clenched that arm into a fist, energy beginning to surge out of it.

Inside Izuku's body and mind, the power of One for All spiraled and sparked as it got stronger and stronger, boosted by the power of the Super Star.

"This power has been entrusted to the next generation by many people… praying that it would work for the good of all. That all of their hopes would become one."

The spirits of the previous seven Users all appear behind Izuku, with Nana Shimura at the front.

"And now it's your turn."

She holds her hand out as the lights from One for All fly out towards Izuku's right hand. As they begin to disappear, Nana gives Izuku some final words of encouragement:

"Do your best… grandson."

With that, Izuku's fist clenched tigher as the lights entered his hand, glowing brighter than ever before. Bowser, in sheer desperation, growls as he breathes fire at the young Hero, but Izuku ducks underneath it, ripping his left arm out of Bowser's grip in the process.

As the flames explode behind him, he screams in pure determination as he lunges forward, before slamming his fist into Bowser's face as his power reaches an all time high. Izuku screamed this out with all his might:

"1,000,000% DELAWARE DETRIOT SMASH!"

Izuku's punch slammed Bowser into the ground, kicking up the rubble and forming a crater as the shockwaves formed into a massive tornado that nearly blew everyone away. The entire kingdom shook, while neighboring kingdoms like the Metro Kingdom, Cap Kingdom, and more, could see the massive tornado. Even Rosalina and her Lumas could see the tornado.

After what feels like hours, the tornado soon shrinks away into nothing, but it left behind a massive dust cloud over the whole battle. Peach is the first to emerge from the cloud, letting out a few coughs as she looks around in the dust surrounding her.

She looked around in worry and concern. "Izuku?" she shouts through the cloud, but receives no answer. "Izuku?!" she shouts again. Still no answer.

As the dust cloud begins to fade and everyone else looks around as well, Toad notices the figure of his best friend in the distance. "Look!" he exclaims as he points, making everyone look.

Izuku, now no longer glowing with the Star's power, was standing over the unconscious and broken Bowser, his fist raised in the air in victory. "The Koopa King has fallen!" Izuku declared out to everybody in the battlefield.

That was all it took for the whole army to start cheering. The Kongs pounded their chests or slapped the ground as Toad and Toadette hugged and laughed.

Peach, meanwhile, ran to Izuku with the biggest smile on her face. As Izuku lowered his arm and turned to face her, he suddenly got nearly tackled into a hug by the Mushroom Kingdom's Princess. "I'm so glad you're okay…" Peach whispered gratefully as tears formed in her eyes.

Izuku, knowing how worried he made Peach, wraps his arms around her to comfort her. "I'm sorry I worried you, Peach…" he whispers as he wipes her tears with his thumb.

"SIRE!" Kamek shrieked as he flew right through Izuku and Peach, knocking the two right out of their embrace. This quieted the cheering as Kamek leapt off his broom and scrambled up to the unconscious Koopa King. "Oh no… Sire… what has that insufferable brat done to you?!"

"Kamek…" Bowser manages to croak out in mid-consciousness, making the advisor gasp. "Get… me… outta here…"

Immediately, Kamek stands up and screams out to all of Bowser's fallen troops. "RETREAT!"

Kamek uses his magic to try and lift Bowser as Bowser's minions and the Koopalings weakly get to their feet and start to run.

"This isn't over!" Kamek declares to Izuku in rage, but Izuku just scoffs. He briefly flares One for All, the green lightning crackling off his body. Kamek flinches and flies off with Bowser in his magic, the destroyed army following behind.

"There they go." Toadette said as she, Daisy, Toad and Donkey Kong walked up beside Izuku and Peach.

"Ha! I've never seen Bowser's army run away so fast in my life!" Toad said with a laugh.

"If that wasn't crazy awesome, I don't know what is!" Donkey Kong said with a grin, nudging Izuku by the side, making him flinch a bit. "You did great, I-Man!"

"Heh. Thanks, DK." Izuku replied with a smile, though Peach had a solemn look on her face, which didn't escape his notice. "You okay?" He asks.

"We may have won this round, but not the war." Peach said with a sigh as she glanced down. "Someday, Bowser and his army will come back, even stronger."

Peach's eyes suddenly widened a bit as she felt Izuku's hand grabbing her hand. She looks down at this, her face a slight shade of pink.

"That may be true." Izuku says as Peach looks up at him, just in time to see him give a smile of determination. "But we'll be ready for him, no matter what he throws at us."

Peach can only smile back at Izuku's courage, she then turns to the others, Toad and Toadette both grin while Donkey Kong gives her a thumbs up and Daisy gives a smirk.

"Thank you, Izuku." Peach says to him and the group, then faces all the Kongs. "Thank you all!"

More cheering erupts from the Kongs as the six heroes gather together in the ruined battlefield, victorious from Bowser's dangerous assault. As they all know, this is only the beginning.

But they would be prepared for whatever he threw at them. Whatever it takes.
