Chapter 2

Half Blood Heartless

"Larxene, Saix. You managed to gain forty-nine hearts from the invasion of Ledgerdomain, and since they are worth approximately eight hearts each, you gained three hundred and ninety-two Hearts. Adequate,"Xemnas commented. "However,Experiments 369 through 389 have all failed,"

"Regardless, I believe striking at a previously unseen, yet incredibly skillful opponent would be quite delightful. I am sure you all remember the chaos caused when the Titan Kronos invaded New York City?,"Xemnas asked.

"Yes,My Liege,"they all answered.

"We need to destroy Percy Jackson and his allies. They are too strong to go unchecked. Not only that, but have you figured out a way to obliterate the Mist protecting them from mortal eyes?"Xemnas continued.

"Of course,"Lex Luthor commented. "With the aid of Adwaita and Blackheart, we managed to diminish the Mist entirely, even though it was forged by the Greek Gods,"

"Good. Lexaeus, take a Heartless spore, and go. Slade, would you mind going with him?"Xemnas queried, but you could see it wasn't a question.

"Of course,my Liege,"Lexaeus stonily responded, and teleported away with Slade in a flash of light.

CAMP HALF BLOOD

"What in the gods are these?"Clarisse LaRue snapped. With the blessing of Ares, she was now impervious to harm, and even the Heartless' black lightning shafts wielded no effect on her. But they did effect her fellow demigods.

"Who knows? Just keep hitting them!"Percy Jackson shouted back,summoning a tidal wave to sweep three Heartless away. Behind him, Lou Ellen, daughter of Hecate, used a magical sphere to stun a Heartless, right as Mark, one of the children of Ares, stabbed it in the back with celestial bronze.

"What the heck are these things? Celestial bronze isn't working on them!"Mark shouted, slashing the Heartless in the chest with his broadsword.

"SHUT UP AND FIGHT!"shouted Annabeth Chase, stabbing a Heartless in the shoulder blade, before swiftly removing it and kicking off.

"Hey,that guy's ordering them around!"Percy observed. Using his sword,Riptide, he lunged at Lexaeus, but the Nobody simply smacked him backwards with his own weapon. Annabeth noticed this, and hurled a dagger from a fallen demigod at his chest.

"Hey,no one hurts Seaweed Brain but myself!"Annabeth shouted.

"Panic!"shouted the satyr, Grover Underwood, before the Heartless was struck with fear,paralyzed and unable to move. Grover smirked, but his victory was short lived, as three more Heartless attacked him. Grover kicked with his superhuman feet, knocking one down to the ground.

Grover sidestepped to dodge a black lightning shaft, before he took out his panpipe, and started a tune. However, Grover wasn't known for his piper skills. Both demigods and Heartless writhed in agony from the horrible notes.

"Come on, my songs aren't that bad, are they?"Grover complained, before leaping almost twenty feet into the air, and landing on a Heartless, smashing its face into the pavement.

"Yeah they are, dude,"commented Lance Alvers, also known as Avalanche, as the X-Men,Misfits and Joes entered the battle.

"Gaia Earthquake Force Rush!"Lance shouted, and an actual fault line formed under three Heartless, and crushed them with incredible force. However, they were still alive. Fortunately,Percy managed to get back up, and fill the fault line up with water,drowning the three Heartless. Increasing the pressure,he crushed the three to death.

"Not bad,"Lance smirked.

The seventeen remaining Heartless,and Slade, charged at the Misfits and Joes. Roadblock fired his heavy-machine gun, but Slade easily withstood the bullets, and landed on Hinton with a kick. Cover Girl and Shipwreck used every ounce of ammo they had on trying to hit Slade, but the Teen Titans rogue engaged them in martial arts. Shipwreck, being a crude brawler, was out within minutes, while Cover Girl lasted a few minutes longer.

"Three meddling flatscans. The Organization will be pleased to be rid of you all,"sneered Slade Wilson. Suddenly, an optical rush of energy pierced him from behind, as Cyclops,Nightcrawler, and Gambit all attacked Wilson.

Nightcrawler teleported away from the battle with a BAMF. "Coward," Slade smirked to himself. Suddenly, he was kicked from behind. Glaring at the culprit, he noticed Kurt Wagner. Sheathing his two swords,he cut off a good portion of Nightcrawler's hair, but did no other damage. Cyclops fired another optical shot, this time at his patella, tripping him. Slade cursed, Scott was obviously fighting intelligently, and wouldn't get close. So all he could do was dodge and fight Remy and Kurt.

Of course, the X-Boys weren't the only ones who fought smart. Lexaeus hurled the Heartless spore at a very unlucky person. Remy LeBeau, or Gambit. Gambit now had black leather clothing, with strange apocalyptic prophecies written around them. His face seemed to be that of one of the mummies from Ancient Egypt. His hair was now in a mullet formation, only now as white as snow. The infamous Hellfire Heartless symbol coated his chest.

"GAMBIT!"shouted Rogue in agony and horror. Without thinking, she charged at Lexaeus, and decked him, square in the nose, sending him flying over seven feet. The earth Nobody gave the life-absorbing mutant an evil glare, before several Hellfire Heartless swarmed her. She punched the ground, sending all of the Heartless flying from the result of the shockwave.

Trinity calmly added an item to their list of 'Mutant Powers to Use against HH'. "Superstrong mutant punches ground, creating shockwave,"Daria smiled.

Suddenly, they noticed another mutant power that worked against the Heartless. Rogue decked one right in the jaw, which did nothing to assist the Heartless, unlike other mutant powers. "Uh, change that to just say pissed off Rogue kills every Heartless,"Quinn muttered.

"What! How!"Slade stuttered. This was an unexpected boon in the heroes' side that would certainly cause trouble for the Organization and the Hellfire Club.

Rogue's rampage was halted by a kinetically charged card, thrown by Remy. The attack sent her flying, as she hit the Hephaestus cabin, plowing right through it.

Annabeth readied a throwing dagger, and hurled it, pegging Remy in the stomach. The Heartless did not seem effected.

"Fira Crimson Whirlwind!"Wanda shouted, and Gambit was picked up by the whirling inferno, and the Heartless roared, as the flames picked away at his body.

"Sweet!"Cooper Daniels shouted eagerly. Cooper had taken a leave of absence, but had returned recently to aid with Heartless disasters, as did the Plumber's Helpers.

"Plumber's Helpers! Distract the Heartless! Percy,Todd,Cyclops,you're with me! We're gonna take down that Lexaeus chump! The rest of you try and stop Gambit's Heartless!"Wavedancer ordered.

From a distance, Cyclops' searing heat vision peppered Lexaeus, but he was nearly immune to the attack, as he simply regenerated easily. Percy lunged forward, and stabbed Lexaeus in the heart with Riptide. Lexaeus thwacked Percy aside with his tomahawk, sending the Son of Poseidon flying. Todd struck with his keyblade, forcing Lexaeus to stumble. Lexaeus blocked the second attack, but the second one damaged him.

"Thundaga Blitzclap Pressure!"Todd shouted. The electrokinetic disk hovered through the sky, and hit Lexaeus dead on. The Silent Hero staggered, the electricity coursing through him. Lexaeus keeled, panting at being hit dead on. Percy followed through with an aquakinetic assault. Morphing the water into arrows, the assault peppered Lexaeus, but the Silent Hero rushed forward, and bluntly assaulted the demigod Son of Poseidon with his enchanted tomahawk. Repeating the assault,Percy was left bruised and battered, but Wavedancer interfered, using a drop kick to force Lexaeus to stumble. Wavedancer and Percy restarted their efforts, along with Todd. Scott stood to the side, firing optical blasts like a trained sharpshooter.

Scott's efforts proved helpful, as Lexaeus's head was smacked to the side. A three-pronged mystical weapon assault hammered into Lexaeus, but the Nobody was certainly not helpless. Three Heartless swarmed the trio. However, the Ares cabin threw them off ,as a combo of kicks,punches, swords,and spears warded off the Heartless. Sadly, the black lightning outmatched the five children of Ares, and their hearts joined the others in the sky. The Heartless ran off, stealing the hearts of a group of Demeter's children.

One stayed behind, leaving Todd alone to fight it. "Uh oh,"the amphibious keyblade-wielding mutant gulped, before swiping his keyblade at the Heartless. Twirling his keyblade back, he hurled it at the Heartless' face, and it returned to his hand. "Sweet,yo!"Todd smirked.

"Hey! That's copyright infringement!"shouted Pietro Maximoff, referring to his own Strike Raid attack.

Meanwhile,Percy and Althea ganged up on Lexaeus, brutally attacking him with Riptide and Althea's scepter. Althea twirled her scepter around, and struck Lexaeus in the nose, before Percy used his blessed sword,Riptide to cut him in the chest. Lexaeus doubled over, and Althea unleashed an upward kick, knocking Lexaeus backward.

"You remind me so much of someone I know,"Percy commented, thinking of Annabeth immediately.

"I hope that's a compliment,"Althea commented back good-naturedly.

Lexaeus reemerged, and struck Percy down with his tomahawk instantly. Althea barely blocked his next attack, as he struck with amazing strength, and Althea was forced on the defensive. Suddenly, Althea was saved, as a large yellow, mechanical dragon descended towards Lexaeus. The Silent Hero Nobody yelped, as the dragon jetted out streams of flames, which blinded him, as well as filling his lungs with smoke. The dragon then proceeded to maul the Nobody, but Lexaeus regained his composure, and blindly attacked, quickly striking with his tomahawk, and the dragon was forced to the defensive. Percy then struck Lexaeus from the side, stabbing him through the hip with Riptide. Lexaeus roared in pain, which only increased as the dragon smacked his face.

"Why is there a dragon automaton fighting the Organization douchebag!"shouted Wanda Maximoff, using a keyblade swipe to ward a Heartless away from a child of Athena. Travis and Connor Stoll then sprayed an odd,green liquid on the Heartless with dual spritzers. The twin sons of Hermes smirked as the Heartless roared in agony, it's body melting from the acidic assault.

"What was that?"she yelped.

"Poisonous centaur blood, mixed with hydrochloric acid,"smirked Connor, readying an explosive pie, which the prankster hurled at a Heartless attacking Roadblock and Storm.

"Why don't you focus on the big Heartless!"Wanda shouted, pointing at Gambit.

"You're welcome!"sarcastically commented Travis, hurling a shaving cream bomb at Gambit, distracting the card-wielding Heartless from Rogue, Blob,Chiron,and Avalanche. Chiron used this as an advantage, and fired an arrow directly at Gambit's eye, before slicing with a celestial bronze sword.

Meanwhile, four sons of Hephaestus glanced over at the automaton that attacked Lexaeus with Percy and Althea. "Man,it's doing great!"Shane shouted enthusiastically, as the dragon cut into Lexaeus, but sighed when Lexaeus sent it sky-high with an upward thrust of his tomahawk.

"Festus' programming is working like a charm!"Nyssa commented.

"I can't believe you named an uncontrollable dragon automaton the Latin word for Happy,"groaned Christopher.

"Hey,Happy the Dragon is kicking Lexor's butt!"replied Shane.

"Lexaeus,"Christopher corrected the demigod,sighing simultaneously

Rogue,Chiron,Blob,and Avalanche all struck at Gambit. Rogue assaulted with an upward punch that would make Ryu proud, before Blob struck with his Heavyweight Keyblade when the Heartless was distracted, cutting it square in the stomach, before Avalanche struck high, his keyblade of the Gaia kingdom ripping into the Heartless' chin.

Chiron fired a tripleshot, each hitting Gambit's forehead. The Heartless roared in agony from the celestial bronze projectiles. Rogue followed up by decking it in the gut, before a kick to the neck sent it stumbling. Rogue rapidly pounded it, before Quinn shouted over the din.

"Hey,sis! Where are you! Gambit's ready to be cured!"the second triplet commented. Althea made sure Percy was still able to fight, then quickly jumped over towards Remy.

"Destiny Kingdom Hearts Reform!"Althea roared, her scepter curing Remy Etienne LeBeau of his Heartless affliction.

"Todd! We need a lightning keyblade for this one!"Wavedancer shouted. Todd leaped over from a battle with three Heartless, and then cured Remy with his Amphibionian keyblade.

"His heart's locked,yo!"confirmed the mutant.

"We need to finish off those freaks first,though,"Annabeth shouted, before gutting a Heartless with her knife. Annabeth Chase backflipped, before dodging three black lightning shafts from that Heartless.

Lexaeus threw Percy aside, finishing the demigod. He decided to help defend the Heartless. Annabeth was leaping through the air, but Lexaeus returned to combat, and a quick smack of his tomahawk sent the girl crashing to the ground. However, before the Heartless could claim her heart, a quick stream of pressurized water pushed the Heartless to the ground,miraculously avoiding Annabeth.

"Thanks,Seaweed Brain,"Annabeth smirked, before drawing her knife. "Wanna help me gut this Heartless?"

"Why not?"Percy rhetorically quipped, before using a pressurized water jet to sent a Heartless backwards. Annabeth jumped at the Heartless, stabbing it in the face.

Shipwreck then joined the duo, his Desert Eagles rapidly firing, as the two rounds of bullets peppered the Heartless, hitting it all over. The sailor then flew at the Heartless, decking it, before a Heartless smacked Hector in the face, sending him to the ground. Since it couldn't claim Hector's heart, it decided to simply kill him. However, the son of Poseidon and daughter of Athena would not allow that, finally beheading the Heartless with Riptide and the dagger Annabeth wielded.

"Not bad, you two,"Hector panted.

JUSTICE LEAGUE WATCHTOWER

"Wow,we're meeting the Justice League. Wow, the Watchers! Wow,the Teen Titans!"Grover Underwood shouted excitedly. Him,Percy,Chiron,and Annabeth attended the latest meeting of heroes, which like always, took place in the JLU Watchtower.

"The Organization seems to have a new strategy of attacking super-powered beings,"Quentin Blud mused.

"Yes, they attacked Ledgerdomain,then Camp Half Blood. And they seem to always be accompanied by a second person,"Spirit commented.

"The Plumbers will watch out for more attacks like that. If they're attacking allies, they may very well attack a Plumber base, or one of the Plumber's allies, like Petrosapia or Darama,"Max Tennyson added.

"Er,Superman? There's some guy named White Knight asking to talk to you,"Mr. Terrific said over the intercom. Superman's brow furrowed, but he did reply.

"Well, let him,"the Man of Steel frowned.

Immediately, a holographic screen appeared in the middle of the room. "White Knight. You're responsible for dealing with those EVO things!"Flash realized.

"Glad I'm recognized. However,Providence does the real work,"White Knight informed the Justice League's speedsters.

"I met that Rex guy once. A while ago, there was a multi-headed EVO rampaging through Steel City. Rex showed up with some Matrix rip off, a monkey,and a group of Stormtroopers, and cured that thing!"Karen Beecher exclaimed.

"The reason I called was because one of Providence's bases is being invaded by Heartless,"White Knight glared. The blanched man, with hair whiter than Remy's Heartless,glared at the heroes.

"Mind assisting? Providence recruits are powerful, but Heartless are worse. Rex,Six, and our other recruits can't hold them back much longer,"

"Flash,John,go. I'll call Captain Atom to accompany you,"Superman instructed.

"I called in one of Danny Phantom's allies, as well as a few other Ghostbusters recruits,"Jenny added.

"I'll go too,"Quentin Blud gruffly commented, the dhampir folding his arms defensively.

"Yo Joe!" shouted Wavedancer, before the Watchtower's Zeta Beam Transports delivered the three JLU members, Quentin Blud,and the X-Men,Misfits,and Joes down to the Providence base.

NEXT TIME ON GATHERINGS

The keybladers join forces with Providence in order to stop Vexen and twelve Heartless. However, it proves to be a bad time for Beast, who finally takes a break from babysitting the New Mutants to go on a mission. Meanwhile, a new keyblade is awarded to a Misfit. Until next chapter.
