Kai VS Moria and Kid VS Oars

In a massive arena somewhere inside the tower, Moria was surrounded by dozens of zombies poised to fight, with the strongest one being Oars the Continent-Puller who Moria put inside of him the shadow of a strong pirate that he defeated previously.

Moria was standing at the top of an elevated platform, a cocky smile stretching across his face. With Oars and the zombie army in his side, he believes that he could defeat the Eustass Pirates and Crocodile.

"Kishishishi!! Make sure you don't leave anyone alive" Moria wasn't going to take the risk of having around a crew with four Supernova and an Ex-Warlord alive.

"As you say, Master Moria" Oars replied immediately.

*Footsteps*-*Footsteps*

Moria heard the sound of something nearby approaching "Huh?..." he shifted his attention to the big iron gate that leads to a hallway.

*Footsteps*-*Footsteps* Kai, Kid, Crocodile and Daz footsteps echoed thorough the hallway. Leading them at the front is Kai, who calmy stopped in front of the closed iron gate with a neutral expression.

He was using his Observation Haki around the place to detect Moria's presence and sought him.

"Someone strong is behind this door" Kid stated, he could also feel a strong presence with his Haki.

KA-BOOOM!! Kai rolled back his fist before punching the big iron gate, destroying it while generating a powerful explosion in the process. Because of Kai and Kid doing Garp's training routine to use Marine Warships as punching bags, their overall pure physical strength has increased by a lot.

The group proceeded to step into the arena afterwards.

"Red Demon!!" Was the first thing Moria said when he saw Kai's face. He quickly shifted his gaze to the other figures as he managed to recognize all of them "'Captain' Kid…Crocodile…'The Killer' Daz Bonez…you bastards, what happened to Ryuma and the other zombies?!"

"Gone, just like you will be in a few seconds" Kai confidently answered that questioned. He wasn't cocky or overconfident, but he genuinely knows that he can beat Moria one on one.

"Screw you!! I've been a pirate since before you were even born!...You think you can come to my territory, destroy my zombies, say shit like that and walk away safely?!!" Moria's veins bulged while shouting that, he looked extremely furious about Kai's words and actions.

"Hmmm…yeah, I think I do" Kai casually responded.

Moria clicked his tongue before breaking into laughter "Kishishishi!! Don't get cocky you little punk, you still haven't seen anything. You think you're that strong because you survived in the first half the of the Grand Line?..."

"…It's called Paradise for a reason. The New World is where you will see the true horrors of the Grand Line, that if you survived this fight in the first place" Moria said while glaring at Kai with hostility.

"Yeah, yeah…*Smirk*…I heard Kaido fucked you up really hard that you had escape the New World with your tail between your legs" Kai mocked, trying to provoke him, which seems to work since he's facial expressions changed when he heard that.

"You know nothing about that monster!!...I once was Kaido's rival, if only I had my current zombie army back then, I could've defeated him!!" Moria declared, hatred filled his eyes and voice when mentioning Kaido's name. After all, he was the one responsible for killing his crew members twenty-three years ago "Instead I lost my crew and had to leave the New World!"

Kai couldn't help but laugh at Moria's declaration, the thought of him defeating Kaido if he had a few mindless zombies with him back then was hilarious "I pity you, Moria. You seem like you miss your old crew so much, let me help you reunite with them again…"

"…by sending you to the afterlife!"

"Kill them all, Oars!!" Moria ordered and Oars nodded his head before charging at Kai and the others.

Oars was incredibly huge that even his footsteps caused tremors.

"That must be a giant" Kid said, his arms crackled with magnetic energy in preparation for battle.

"But it's bigger than a normal one" Crocodile remarked.

"With that size he must be very slow!" Daz assumed before turning his arms into sharp blades and charged at Oars.

Moria was confident about Oars strength "Kishishishi! You stand no chance against him!"

"HOOORAA!!!" Oars roared loudly before punching down Daz at a speed that you would not expect from someone his size.

"He's fast!!" Daz was shocked as he barely avoided Oars fist and jumped to the side.

BOOOOOM!!! The simple punch from the giant Oni was enough to destroy the ground. Oars immediately attacked Daz again, and this time he tried to stomp him with his feet.

Daz leaped backward dodging it before Oars punched him down again. This time Daz climbed on the Oni's arm and run up towards his head before he swung his bladed arms in front of him, resulting in several powerful horizontal slashes.

"Chaotic Slash!!"

However, the slashes were not strong enough to pierce Oars tough body and the latter took him by surprise and punched him away with his giant fist, sending him crashing out of the building.

"Huff…Huff…What a power…" Daz looked shaken as he took a lot of damage from that punch.

Oars then shifted his focus to Kid and Crocodile and proceeded to attack them as well.

"Hahahaha!! I've been itching for some action, let see how long you could keep up, you big rotten fuck" Kid looked at him with excitement while using his magnetic power to attract dozens of metal scraps towards him.

"RAAAAWWRR!!!!" Oars roared loudly while throwing a strong right punch, aiming to smash down Kid and Crocodile at the same time.

Kid quickly formed a massive makeshift metal arm that was as big as Oar's fist itself, and then punch him back.

BAAAAM!! When the two fists clashed, the force behind their punches generated a powerful shockwave that cracked the ground and the walls around them.

"What?! You blocked my punch?!" Oars was shocked from that. However, Kid was still getting pushed back a little because of Oars' massive size and strength.

Oars swiftly pulled back his fist and then tried to kick Kid. The latter predicted that with his Observation Haki and used Soru to dodge it with ease before he leaped into the air and slammed his giant metal arm into Oars face.

"Punk Gibson!!"

BAAM!! Oars lost his balance from the force of the punch and crashed into the wall behind him. But due to his zombie body, he felt no pain even though he received some damage from the attack.

The two found themselves outside the tower afterwards. The former quickly got up again and sent a barrage of fast punches towards Kid which the latter dodge easily, but the aftershock of the attacks pushed him away a little.

"He's faster than his size…and he could even destroy warships with those kind of punches" Kid remarked while landing a few meters away from the giant "I need something strong and flexible to fight him"

BAM! BAM! BAM! Oars gave Kid no time for thinking and threw several other punches at him at a high-speed prompting Kid to retreat before using Soru to close at him from behind and strike him with his giant metal arm.

Once again, the attack landed and almost threw Oars out of balance, but he quickly got his footing back and punched away Kid.

Oars also seemed to be losing his patience because of Kid constantly dodging his attacks. Whoever the shadow inside of him belongs to, he was certainly an impatient person "You're an annoying little man! I'll crush you like an ant!"

"You're just a talking corpse, this next move should be enough to take you down…" Kid declared with a confident grin as he attracted hundreds of more metal pieces from all around the Thriller Bark "More…I need more!!"

Nearby Moria and Kai were facing each other, when Moria noticed the metals flying out of the tower and into the direction of Kid and Oars battlefield, he couldn't help but get curious and glanced at their direction.

"What the hell is that punk trying to do?" Moria questioned, tilting his head and avoiding a large flying spear "That bastard caused a lot of destruction to my mansion"

"Hoi, edge lord! You should be worried about yourself instead of your zombie" Kai said to him, he was completely confident about his brother's strength and didn't not worry about him at all 'We promised each other to flip the world upside down, if he gets defeated by a stupid zombie, I will kill him myself' is what he thought.

"…MORE!!!" Kid kept attracting hundreds of metals until he gathered a large amount, enough that he could create anything he imagine with it…and so he did.

Using his magnetic ability, he shaped the metals into a gigantic humanoid robot made of scrap. The robot is composed of a head with a human-like face where Kid seated himself in and controlling the robot from there, two arms with massive drills attached in the forearms and long legs.

"Punk Gunman!!"

Although the robot was big, but it was nowhere near Oars' size.

"What the--?!!" Oars gasped in surprise when he saw that "I don't know what kind of weird ability you possess, but I've had enough dealing with you!!"

Oars immediately attack Kid by slamming his fist forward at him.

"Hmph, you think you can defeat me with that pathetic punch, huh? Who the hell do you think I am?! Eat this you stinky corpse!!" Kid controlled the robot and made the massive drill in the right arm spin at a high speed before he thrusted it at Oars' fist.

"Heaven Piercing Drill!!"

SPLASH!!! The drill pierced through Oar's fist and smashed his arm. Oars attempted to strike Kid with the other one, but the robot swiftly jumped in the air using the magnetic power to float before flying towards Oars' head at a high speed.

SPLASH!!! While the drills on the robot's arm were spinning, Kid delivered a powerful thrust at Oars' neck, decapitating him right away and causing the shadow that was inside of his body to leave and go back to its original owner.

After hearing a loud crash, the defeat of Oars the continent puller was announced. While Kid was doing that, Crocodile and Daz Bonez were holding off the rest of the zombies.

"H-He took down Oars?!" Moria was shocked, he stopped fighting Kai for a second not believing that one of his trump cards was defeated that easily.

"What are you looking at?" Kai asked, hardening his arm muscles until they bulged while holding Shichiseiken in his right hand.

<Seven Star's Earth-Shattering Slash>

Kai swung his sword downward, generating a rapid, green flame slash wave that traveled across the ground, destroying it along the way.

"AARGHHH!!!—Is that green fire?!!" Moria yelped in pain after falling on his back as he got slashed across chest while green flames burned his wound. He quickly summoned a dark silhouette--or a shadow clone behind Kai using his own shadow, and then swapped places with it "Doppelman...Shadow Warrior!!"

With a wicked grin and a big scissor in his left hand that he seemingly pulled out of nowhere, Moria tried to pull Kai's shadow from behind and extract it while oblivious to the fact that Kai already knows his ability very well.

"You think I'm that stupid?" Kai quickly turned back and kicked away Moria's arm, breaking off his attempt to steal his shadow.

He then leaped back before he swung his right leg upward and sprouted multiple long tendrils of cloud from it, giving it an appearance similar to a willow tree, the ends of the tendrils being shaped to mimic his foot and used it to repeatedly stomp down Moria.

"Willow Cloud!!"

BAM! BAM! BAM! Moria crossed his arms in front of him reducing as much damage as he could before he used his shadow clone to teleport a few meters away from Kai.

"Huff…Huff…You bastard" Moria wiped the blood off of his mouth as he raised his hand and transformed the Doppelman into a myriad of balls, which turned into a swarm of bats that attacked Kai.

"Brick Bat!!" Because the bats are so small, numerous, and immortal, this attack is usually very difficult to counter or avoid, and the constant annoyance can make opponents get fatigued quickly, but thanks to Kai's Logia body it wasn't effective at all.

"You're a Logia?!" Moria gritted his teeth before sending another wave bats "Then how about this? Brick Bat..." he sent several large bats that transformed and completely encased Kai in a black box made out of solidified shadow.

"…Black Box!...Kishishishi!! Now you won't be able escape even if you're a Logia" Moria charged towards Kai who was trapped inside the black box and attempted to smash him with his hands. But before his fist could make contact with the box, a fist sprouted out of it and punched Moria in the face sending him hurtling backwards.

"Moria, Moria…You should be more creative, otherwise you'll go down pathetically. You know, if one knows he's gonna go down he should at least go down in an epic way" Kai said with a smile while resting his sword on his shoulder.

"Screw you!!... Spiky Shadow Lizard!!" Gathering his shadows together, Moria shot out a large shadow spear at Kai, the tip of this spear resembled a horned lizard.

Kai slowly walked towards him not bothering to dodge the spear as it pierced his chest without leaving any damage.

"How disappointing, you should at least know some basic Haki since you've been into the New World and clashed with Kaido. Maybe you did and just that he fucked you up hard enough that you lost your will and your ability to use it…Anyway, I'm not gonna stretch this boring fight any further"

*Lightning*-*Lightning* Kai's left hand crackled with electricity, and he proceeded to summon a large lightning bolt, grabbed it with his hand and hurled it towards Moria.

"Indra's Vajra!!"

"ARRGHHH!!!" The lightning bolt pierced Moria's chest and shocked him.

<Seven Star Arc Waves>

Kai didn't stop there and attacked him again, he swiped Shichiseiken erratically at great speed, successively producing multiple cutting, flame waves that hit Moria and sent him flying out of the building.

Moria's chest was covered in blood as he sustained multiples sword injuries, if it wasn't of his unusually big and tall body which is almost seven meters tall, he would've been dead by now.

Seeing the hopeless situation, Moria had no choice but to use everything he got to defeat Kai who he did not expect to be this strong. He proceeded to absorb the shadows of his zombie minions, absorbing 1000 shadow into himself.

The large number of shadows increased his proportions to rival that of Oars. His neck bloated to extreme proportions. His horns became longer, and his hair became spiky. His arms also became very huge while his legs became longer compared to their original stubby appearance.

"Shadow's Asgard, 1000 Shadow!!!...Kishishishi!! Behold my strongest form, with this you'll stand no chance against me red demon!!"

Kai calmly gazed at the colossal Moria, he can remember very well the weakness of this form 'This is more like a final desperate move than a trump card' Kai thought in his mind 'because of the number of shadows that he absorbed it's hard for him to control them and keep them inside his body…I could just punched them out of him'

"Take this!!!" Moria roared while using all of his power to punch down Kai with his massive fist.

KA-BOOOOM!! His attack was strong enough to split Thriller Bark in half.

But even though Moria gained incredible strength, his speed became very slow and with Kai's speed and Observation Haki it will be impossible for him to land a hit.

Kai turned his left arm into clouds, enlarged it until it was as big as a giant arm and punched Moria's stomach, forcing him to release dozens of shadows from his mouth.

"Aghhh!! The shadows are escaping!!" Moria used his hands to cover his mouth and force the shadows back into his body.

Kai smirked seeing that "I was right, it's hard for you to keep all those shadows inside of your body"

"You little shit, I'll make you pay for this!!"

BOOOOM!! Moria punched down Kai again, which the latter easily dodged.

"Time to end this you edgy fatso"

SWOOOSH!! With a serious look on his eyes, Kai gripped his weapon tightly before using a combination of Soru and Geppo to approached Moria mid-air while holding his sword in his right hand, he infused it with a thick layer of lightning on top of the green flames that the sword produces, and then swung his sword horizontally, creating a powerful slash attack.

"Divine Retribution!!"

Lightning! Lightning! BOOOM!! The attack was powerful enough to create a massive radiant sphere as the lightning surged out from every direction and shock Moria.

"AAAGHHH!!!--" Moria's chest was cut open and blood splashed everywhere as he was sent crashing into the large tower unconscious. All the shadows inside his body begin to escape, as the tall building came crumbling down on him.

Kai landed beside him and slowly sheathed his sword.
