The groups had soon arrived at the entrance to the Keyblade Graveyard as they had all steeled themselves for the battle that is to come.
"The Keyblade Graveyard is on the other side of this cliff." Mickey said.
"Wait...someone's here." Sora said as the desert winds blew as stepping forth from the dark was Master Xehanort himself.
"Xehanort…." Hope said.
"Legend has it that darkness once covered the world. We know so little about the Keyblade War, only that it was the beginning. If ruin brings about creation, then what then would another Keyblade War bring? When the darkness falls, will we be found worthy of the light that will be created?" Xehanort asked as Ansem appeared by his side.
"Or will all of creation instead be returned to the shadows?" Ansem said. "Today we will recreate the legend and see."
"But first...all of your lights shine far to brightly." Xemnas said appearing. "It must be extinguished in order for the truth to be seen."
Then at last, Young Xehanort and Vanitas appeared.
"Only when your hearts have been broken by battle upon battle can the key be claimed to Kingdom Hearts." Vanitas said.
"And break you is what we shall do. It has been etched." Young Xehanort said as darkness filled the sky and raining down from it were armies of Heartless, Nobodies and Unversed.
"Look at how many there are!" Sora said.
"Ready, guys?" Hope asked.
"Hell no, but let's do this anyway!" ZS said.
"Prepare to face the light and darkness!" Ace said as he readied his Keyblade.
The guardians invoked their keyblades as the massive Army of Darkness charged.
The Keyblade War had begun.
"O Origin of truth, come forth!" Estelle called.
Effreet, Gnome, Sylph, and Undine appeared as they unleashed their power.
"A grim blaze!" Efreet called.
Gnome appeared sitting on a boulder as it crushed a group of enemies.
"A heartless storm!" Sylph called.
"Raging Billows!" Undine called as more of them were swept away by a Tidal wave before being trapped in an orb as Estelle floated into the air.
"Boundless emotion unleashed! Ultimate Elements!" Estelle called as she pierced through the orb as it exploded. "These are the principles of the world."
"Sora, Estelle gave you an opening, now's your chance!" Hope called.
"I got it!" Sora said. "Attraction Flow: Mountain Coaster!" Sora summoned the Big Thunder Mountain coaster as he, Donald and Goofy hopped on. Using the chimney flares, the massive armada was blown away as the dust settled.
"Well that wasn't so hard." Mineta said.
"Don't drop your guard yet. The real fight has just begun." Naomi said.
"The others have gone on ahead." Ace said.
"Let's meet up with them." Hope said as the group ran to catch up with the others. As they did so, they saw someone through the dust.
"We're all here now….so let's go and settle this." Theo said.
"Yeah. Huh?" Ven said as the group said a familiar figure stepping through the desert. The figure was none other than Terra. "Terra!" Ven said starting to run before Rainbow stopped him.
"Don't go any closer. That is not Terra." Rainbow said.
"Yeah...that's Xehanort in there. Which means…" Hope said as Terra's hair turned as silver as Xehanort's.
"He's the 13th member." Jexi said.
"Today is the day you all lose. Before you even face the thirteen, you all will be torn heart from body. But fear not...the X-Blade will still be forged." Terranort said.
"That's not gonna happen, we will stop you." Ace said.
Terranort then summoned a grim keyblade and charged at Ventus.
"No Name...but why does he have it?" Naomi pondered before something blocked Terranort's advance.
"What the?" Odd said.
"See...you guys weren't the only ones preparing. While most of us either trained or rested...I went and brought an old friend who wanted in on this." Rainbow said as the dust cleared to show Terra's Armor blocking Terranort.
"Terra's armor!" Hope said.
"More precisely...Terra's lingering will." Rainbow said.
"This is impossible!" Terranort snapped.
"How I've waited for this moment." Terra's lingering will said. "Now….return to me my body and heart!" he said swinging his keyblade as it changed into a whip as it wrapped around Terranort's No Name as he started whipping him around. As Terranort let go, he lunged for the armor. "Now's the time." he said as his keyblade changed into the Ultima Cannon as it unleashed a large blast of light against Terranort.
Terranort resisted the Ultima Cannon as much as he could. He then summoned No Name again as he and Terra's lingering will clashed.
"Terra!" Ven shouted.
"Ven, no. Them first." Aqua said as more enemies came towards them but not before the ground opened as a large combination of heartless emerged.
"A Demon Tide too...somehow I'm not surprised." Jexi said.
"Let's bring it down." Al said.
"David, wanna do the trick we did in Twilight Town?" Hope asked.
"You know it. You all know what to do." David said.
Everyone then held on to David.
"Do it!" Hope said.
"Zone Speed: The World!" David shouted as time stopped.
"Now instead of one Heartbinder… let's do all five of them!" Hope said.
"If it's summoning time, count me in!" Simon said.
"David, Hope, Jexi, Simon, Mark. you all each take one." Sora said.
"Sora, not all of us are summoners." Jexi said.
"Then give them to me." Topaz said as she started chanting something as magic filled the five summons.
"What's going on?" Peridot asked.
"Topaz is a summoner. She used to summon allies." Cobalt said. "Though this is something out of her normal comfort zone."
Soon the five summons appeared and started to attack the demon tide.
"Time has begun to flow again." David said.
Time resumed as the effects of all five summons hammered the Demon Tide as it broke apart.
"Did we get it?" Ivy asked.
"No… it's not done." Theo said.
The Demon tide then began to swirl around like a fierce storm as thousands upon thousands of heartless, nobodies and unversed were being devoured within it.
"It's increasing its strength by assimilating more enemies." Tetsu said.
"That's not a demon tide…" Sci-Twi said as the millions of enemies became a giant tornado of darkness. "It's a Demon Horde!"
"Really? I was going to go with Demon Calamity." Emerald said.
"Whatever you want to call it, it's gonna wipe us all out if we don't stop it!" Theo said.
"Just attacking it won't work anymore. Unless we can get to the core, this won't end. But with all those heartless, it's gonna be hell breaking through." Yang said.
"I'll stop it!" Sora said as he charged right in before seeing a vision of a grey haired boy standing before him. "Huh?"
"Need some help?" he asked before hundreds upon hundred of keyblades flew towards Sora.
"What...what is this?" Lacy asked.
"These...these keyblades…" Naomi said shedding a tear. "Nice to see you all again...my dandelions."
"These are ancient keyblades from the time of the first war. The hearts of their former wielders...they've heard our plight." Sheer said.
"Okay!" Sora said jumping onto the keyblade wave and riding it to the Demon Calamity. "Let's go!"
Sora then struck the demon calamity with Keyblade upon keyblade as the names of all the wielders echoed in his mind.
"You can do it Sora!" Hope called.
"Yeah! Slay that calamity!" Jexi shouted.
"Go Sora, go!" Eddy cheered.
"Gun it, Sora! Straight through!" David said.
"Let's go guys! We're almost finished!" Sora said as he and the other keyblades had whittled down the calamity to a core as they rushed through it, destroying the Demon Calamity for good.
"Oh, yeah!" Hope said.
"So much for breaking us. Was that really Xehanort's best he could do?" Bakugo asked.
"No… he hasn't played all of his pieces just yet. Look." Shoji said as walking up, in his dark suit, was Riku Replica.
"It's the fake." Mari said.
"And it looks like he's got down all the details. The dark suit and the long hair… the exact Riku from when Ansem had control of his heart." Hope said.
"The one from Castle Oblivion." Roy said.
"I'd say that was our finest hour." Riku Replica taunted.
"No...it was my hour of weakness." Riku said.
"Care to prove that?" Repliku asked as a large shadow came from the replica. "Let's have some real fun now!" he said as several Demon Towers rose up. "If you survive...we'll all be waiting up ahead." he said vanishing.
"Ye must desire respite from thy empty existence. Thou shalt have it!" Atro chanted as angel feathers gathered into the sky. "Celestial Star!" he called as beams of light rained down on them only for more to appear. "Damn."
"They keep coming!" Hope said as Atro prepared to attack again. "No, save your strength! We gotta be as fresh as we can for Xehanort!"
"Well then what are we supposed to do?!" Sonata asked.
"We can't keep this up forever!" Lea shouted before a ray of light shined down before them as a dome of light surrounded the group as Yen Sid stood before them.
"Master!" Mickey said.
Yen Sid waved his hands as the light held the enemies back while also creating a path. "Go, my young champions! I shall hold them off for as long as I can!" Yen Sid said.
"What? But we can't just leave you here!" Sci-Twi said.
"We'll stay behind!" Donald assured. "You guys go on ahead!"
"We understand. Catch up to us as soon as you can." David said.
As the group went through the path of light leaving Donald and Goofy behind, the groups hurried to the entrance of a massive labyrinth as Xehanort and his 13 darknesses stood atop the entrance as he smiled.
"It seems you all have come." Xehanort said.
"And we're here to settle this. 7 Lights against your 13 Darknesses." Hope said.
"Yes. I have waited patiently, but together...we shall unlock the Keyblade Wars secrets." Xehanort said.
"Ngh… We're not going to let that happen!" Naomi said.
"She's right. We came here to settle things once and for all." Sunset said.
"Very well." Xehanort said as most of the members of his group removed their hoods leaving only one left hooded as they spread out across the labyrinth. "Now, we forge it, the ultimate key…. The X-Blade!"
The heroes stood still as the final battle began.
"What do we do now, Hope?" Theo asked.
"...We fight." Hope said as the keyblade guardians split up across the labyrinth as the heroes soon did the same in order to start searching for the 13 darknesses.
