Narrator

The group of demigods didn't need to travel far to find Xander, because he came right to them. With a whisk of the wind, Xander appeared about twenty feet away from the Argo II, parallel to the side facing the collapsed cavern. They walked around the large battleship and were immediately met with the terrifying sight - Majin Kai grinning at them.

"The demigods are here to play" Majin Kai clapped his hands together like a child

"I guess this is it then" Frank said

"Are you ready Percy?" Layton asked, referring to that hidden and powerful technique the demigods had been working to perfect for this very moment

"I... yeah, I am" Percy forced confidence upon himself

"It's so sad that Arachne has died" Xander said. "But, it stops me from having to share my revenge on Athena"

"You'll die like her" Annabeth scowled

"If I do, then certainly not by you" Xander chuckled and raised his hand

Behind Xander and the Majin, the ground opened up and an army of around a hundred undead members of their cult crawled out, each wielding a weapon and dressed in old Greek armor.

"Ok, undead warriors. I don't think we prepared for this" Leo said

"I think we've got enough people" Jason assured

"Two people help Percy keep that Majin in place so he can do his thing. I'll try and ward of Xander though I'm not sure if I can do much. The rest of you re-slay those skeletons" Layton said

"I'll help you" Annabeth said to Percy

"Annabeth, you're not in fighting shape" Piper said

"I can help Percy. I can summon my own skeletons that can distract that... demon" Nico added

"I'll help too" Jason volunteered

Despite wanting to argue, Annabeth chose not to, because they were right. Her fate in the final battle: to watch. Watch as a world-ending battle went down right in front of her eyes, and unable to do anything. Percy walked her back and sat her down against the Argo II as tensions arose tens of feet in front of them.

"We'll win, I promise" Percy said

"Don't die Seaweed Brain" Annabeth scowled sternly

"I won't" He chuckled and gave her a last kiss before rejoining his friends

Majin Kai still looked as fierce as ever, despite having been in a lamp for past six days. The demigods thought that was the reason behind his crankiness and child-like behavior, but that was just how the demon acted. Xander hadn't really put in a personality to the demon during the creation process, so fate gave him the childish personality.

"So. Are you demigods prepared to die?" Xander asked

"No demigods will die today" Majin Kai surprisingly said. "No need to waste such powerful and fun demigods for your dreams"

The demigods never saw the plot twist coming. Majin Kai extended his arm out to his side and killed his master, his creator, and the evil Sorcerer Xander with a large blast of ki that disintegrated him.

"Gaea was going to kill him anyways" Majin Kai laughed and the sound echoed across the entire flat area

"Gods... well, I'm not complaining or anything..." Hazel said

"He's unpredictable. Stay on guard" Layton warned. "He won't kill us, but he'll make us the closest thing possible"

The army of skeletons charged forward and so did the demigods, meeting up at the halfway point. Percy, Jason, and Nico pushed through the conflict and stood in front of Majin Kai as the large battled commenced behind them.

"So you three will be my first playthings" Majin Kai licked his lips

"You'd really kill your own master?" Percy questioned, stalling for time as the burning sensation in his chest began to flare up, just like had been taught

"I was only a pet" Majin Kai twitched, itching for battle. "Just like I will make you three"

Nico and Jason lunged forward and severed Majin Kai's arms off. The demon frowned, looking at his arms that rested at his feet, and then kicked Jason away. One arm hopped off the ground and reattached itself to the body. The Majin wrapped its elastic arm around Nico's neck, squeezing it tight.

"You've brought me a son of Hades..." Majin Kai said. "I don't like those demigods. They're like black licorice"

Jason recovered and decapitated the demon, causing him drop Nico, who fell onto his back. He quickly got up, but the body of the Majin lunged forward, not caring to reattach the head. Clearly it didn't need the head to battle, as Nico and Jason were left blocking fists with their blades. Hitting Majin Kai would be like punching quick sand, but as the demon threw his fists, they felt like solid Imperial Gold upon impact with the sword.

Behind them, Percy was concentrating, trying to tap into that soul energy he had been practicing. However, he was finding it difficult as he was forced to watch his friends struggle in front of them. Majin Kai's head hopped back onto the body and did a 180 before facing forward. Jason stepped inside the majin's guard and kicked him back, giving a short pause to the battle. Using that pause, the ground opened up next to the majin and four skeletons emerged, ready for battle.

Majin Kai frowned at the sight but then turned back to Nico, holding out his palm and firing a blast of ki that the son of Hades only narrowly damaged to dodge. Behind him, a small explosion went off. Two skeletons lunged forward and began to attack the majin along with the help of Jason as Nico quickly caught his breath.

Around Percy, gravity got heavier and his knees buckled, but he quickly stood back up and resisted the force just how he practiced. The burn in his chest reached maximum heat, threatening to explode as a dark aura slowly expanded out, covering the son of Poseidon. The majin seemed to recognize whatever the demigods were up to, because he began to panic. A shockwave of ki shot out from Majin Kai and threw Jason and the two skeletons back.

"So you choose death!" Majin Kai exclaimed, firing a ki blast at Percy

Nico quickly jumped in the way and sliced the blast in half with his Stygian Iron sword. The two halves waved around in the air recklessly before landing behind Percy in an explosion that nearly missed him.

Switch

Not only were each skeleton decently skilled, after they died (being turned into a pile of bones), they simple put themselves back together and stood back up, ready for combat. It was if eight against one hundred wasn't fair enough already.

Piper slashed away at the skeletons, assisted by Hazel who sticked close to her. Next to them, Frank had transformed into a grizzly bear and began to maul away at any skeletons that would come close to them. Victor cleaned through skeletons left and right, occasionally calling upon vines that would stop any that attempted to get the jump on him. Leo occasionally blasted fire while Ryan fought with his golden sword that was caught ablaze, turning any skeletons that regenerated from a clean white color to a burnt black. In the corner of the conflict, Layton kept skeletons away with Funem Celer - the blade extending out like a whip to tackle several skeletons at once. On his right, Chloe fired off explosives arrows from her bow which required more of a waiting time for the skeletons to recover, as their pieces would get sent scattered.

"That thing's cool! Where'd you get it?" Chloe asked

"Local Walmart" Layton replied

Chloe pouted as she fired another arrow. "I was just wondering, cause, you know..."

"Know what? That I kill people for a living?" Layton said as he punched his free right-hand through a skeleton that had gotten close, shattering it to pieces

"But that's not really you, right?" Chloe questioned hopefully, momentarily stopping from firing off arrows

"Not technically. Too long of a story" Layton dismissed.

"Well then, you owe me an explanation later" Chloe said. "If um, there is a later. Not to be pessimistic or anything"

"You know, that's weird" Layton decapitated a skeleton. "Why are you so interested?"

Chloe blushed just a bit. "I- um... I've just heard a lot of things about you. My mom is Selene, and I always hear people call you The Fist of Selene"

"No one's ever called me" Layton said

"Where I come from they do"

"And where's that?"

"New York" Chloe answered simply

"Yeah, I try to stay away from there" Layton replied. "Tell you what: fight now, explain later"

"Sounds good to me"

Nico had used up most of his energy calling on skeletons, but Percy seemed to still need more time. Much more time. He tried to help Jason but was quickly thrown back as Majin Kai's arm extended out and hit him square in the face. That same arm then moved to the side and wrapped around Jason's neck, keeping him in place. Majin Kai began to pummel the son of Jupiter with his fist multiple times as his other arm held him by the neck.

At the sight of the scene, Percy began to rush the process, but quickly went back to a normal as he seriously thought he was going to explode. Every single inch of his body felt like a dagger was stabbing through it, and his chest was the worst of it - burning like it had its own sun inside. The dark aura began to calm down and Percy felt himself lift up his palm - the same way Majin Kai did to fire a ki blast.

"Percy... how much longer?" Nico croaked as he picked himself up off the ground and rubbed his cheek where he had been hit

He didn't reply, but guessing by his facial expression, Nico decided against pressing for an answer. Majin Kai had finally gotten bored of using Jason like a punching bag, so he unwrapped his arm and Jason felt to the ground.

"Is that all you got?" Majin Kai asked. "The original son of Zeus was much more powerful then you"

Thunder crackled in the distance as grey storm clouds rolled in above the scene of battle. A powerful blast of lightning shot down from the clouds and electrocuted Majin Kai. Being elastic and practically invulnerable, he wasn't injured, but he certainly had never felt that kind of sensation.

"Perhaps you are stronger than I thought you were" Majin Kai frowned and rubbed his forehead with one finger

Nico helped Jason up and they braced themselves, knowing they didn't have much left in them. Majin Kai studied the two demigods with interest, wondering how they still had the will and energy to fight. After a few brief moments of silence, the majin lunged forward and Jason caught him off guard, severing one arm off and calling upon a small blast of lightning that reduced it to ashes. Nico side stepped and decapitated the Majin. While it was easy to do limb-severing, it was ineffective in the long run. However, it finally seemed as if they had done something permanent.

"My arm..." Majin Kai said as he used his spare one to pick up his head and place it back onto his body. "You destroyed my arm..."

What use to be Majin Kai's right arm was now nothing more than a black smudge on the rocky surface of the ground below the fight.

"That...," Jason exhaled deeply, "was for treating me like your personal bodybag"

"That's because you are" Majin Kai laughed

A strange sound - similar to something being melted down into goo - was heard, and red substance began to escape Majin Kai's right shoulder. In an instant, a new arm popped out of the flat surface of the majin's

"You think just like the old son of Zeus - that blasting things to pieces with your lightning will solve your problems" Majin Kai said. "No... you will die for that"

The Majin lunged again, careful to not get anything decapitated. Somehow, he had gone from a reckless fighting to style to a collected and skillful one. Jason swung his sword but Majin Kai blocked with his wrist. Nico swung his blade identically, but it was also blocked with one interception of the wrist. The demigods tried to push their swords forward with all their might , but the majin's arms now felt like solid material.

Finally, the demigods gave enough force that Majin Kai lost his footing and stumbled back.

"You're weak, son of Hades. Perhaps the weakest of his offspring I have ever seen" Majin Kai mocked

Nico scowled and slashed his sword, chipping a small chunk of his arm off that instantly regenerated.

"I will make you a deal" Majin Kai said

"What?" Jason asked

"I will spare you if you take me to Mount Olympus. There, I will absorb the gods and become the most powerful being in the universe" Majin Kai explained

"Not a chance" Jason waved his sword

"Then you'll die defending gods who don't care about you" Majin Kai began to walk forward

It happened so fast, Jason and Nico could've sworn that it had been a figment of their imagination. A dark purple and black orb of energy zoomed past their faces and made contact with Majin Kai's chest. Instantly, the majin began to melt for a few moments until he exploded into purple sparkles. Behind them, Percy collapsed and they wasted no time in rushing over and checking him out.

"Did I... hit him?" Percy asked

"Yeah, you did" Nico smiled

In front of them, the skeletons all froze like statues and then disintegrated into ash that was carried by the wind. The demigods who had been working their way to keep the skeletons at bay looked around in confusion at the fact the enemies they had been fighting so hard against had mysteriously disappeared. Then, they noticed the absence of a majin and a Percy on the ground.

"Holy smokes... you did it" Leo said as the demigods gathered around

"Totally... out of energy" Percy breathed heavily

Leo smiled. "Just you wait until the gods hear about this one. They'll give us a big feast and plenty of pra-"

The wind whirred and the demigod turned to see a small patch of pink slowly but surely gaining mass. Layton quickly fired a column of fire at the growing red mass, but it did nothing as Majin Kai regenerated himself.

"I had a feeling you would do that..." Majin Kai gritted his teeth angrily. "That's cheating, son of Poseidon"

"That chunk of his arm I cut off... he tricked me" Nico realized. "He purposefully agitated me"

"Not strong, but certainly smart. From the very moment Poseidon's child began to charge that energy, I knew I needed to have a spare body part around" Majin Kai explained

"Which is why he got mad when I blasted his arm" Jason muttered. "He knew he was running out of time and I ruined his get-out-of-jail-free card"

"I... I can't do that again" Percy said

"You will have no other chances of victory" Majin Kai flicked his wrist and a blast of ki hit the ground in front of the demigods, causing a large explosion
