"They can take your world. They can take your heart, cut you loose from all you know. But if it's your fate, then every step forward will always be a step closer to home."

This is the story of the battle between Light and Darkness. A game of chess where the pieces are set in motion. 13 darknesses against 7 lights. And now, that battle will reach its epic finale.

But our story doesn't start in the climax of the War of Light and Darkness. No, it begins elsewhere.

Where at long last, the time had finally come. The planets had finally achieved perfect alignment, and the plan Hades had forged 18 years ago would finally come to pass. The Fates had predicted this future. The day he would seize control of Mount Olympus and rule all the cosmos.

His previous attempts to advance his plans with the use of Terra, Cloud, and Auron had failed, for the hour was not yet right. Now that the planets were aligned, there was nothing that could possibly go wrong. A wave of darkness waved down from their celestial rank, one by one, Hades freed the Titans from their prison. With the freed Titans and his hatred of Zeus having been reinvigorated...Hades began his attack on Olympus.

Which brings us to our heroes. Hoping to help Sora regain his lost strength and the Power of Waking, the quintet of The Dimensional Heroes, Shining Hope Squadron, Brave Adventurers, Spirit Force, and Team Chronicle accompany Sora, Donald and Goofy to Olympus Coliseum to consult Hercules for answers, however…

"Okay...I know we haven't been here in a while...but I don't think this is the Coliseum, fellas." Applejack said.

"But it is Olympus and...home." Medusa said.

"Still...no fanfare?" Sora said mimicking a trumpet call as Donald listened.

"Nope. Nothing." Donald said.

"Looks like we missed it." Goofy said.

"Did we take a wrong turn when Sora opened the gateway? Or did someone not read the map right?" Hope asked looking to the Eds.

"What? We took the right turn at Wonderland just like the map said!" Eddy said.

"Then we must be somewhere else on this world." Jexi said.

"Maybe those guys know." Ed said pointing at familiar enemies.

"Those aren't locals. Those are Heartless!" Sora said.

"Here they come!" Ace said summoning Summoner's Oath.

"Man your battle stations!" CP called out.

"Oh, it's on." Rainbow said summoning Earthshaker as Sci-Twi summoned her keyblade.

Together with Sora, Donald and Goofy, the group dealt with the Heartless.

"How come the Heartless are here? We already helped Herc with his inner demons, so why are they showing up?" Gemini asked.

"Something's wrong." Ace said as he looked up the mountain.

"We'd better find our way and locate Herc." Hope said as they advanced through the cliffsides. Though when they finally exited the inner caves, they came out to daylight and saw the sea but no Coliseum.

"Ugh, this is getting us nowhere, we're going in circles." Jiro said.

"Sora…" Donald grumbled.

"Hercules! Where are you?" Sora shouted out as a large ball of black smoke came down behind the group.

"Okay, I know I dotted my i's, crossed my t's and zeroed the hero. So what gives? Who could possibly be giving me a migraine by yodeling that yutz name?" said a familiar god of the Underworld.

"This presence...Hades?" Medusa asked.

"Who else?" David asked.

"Great. It's just these guys. Oy vey." Hades said.

"Just us guys, really? That's cold, even for you." Pit said.

"Don't forget. I can always TURN UP THE HEAT!" Hades shouted.

"I thought Hades would be more...calm and collected." Medusa said.

"Not the one you're familiar with." Hope said.

"But if he's here, then where's Herc at?" Rainbow asked.

"What is everyone's infatuation with that dolt!?" Hades shouted. "You know what? Nevermind. I'm cool! I'm good. Because...Wonder Boy will be out of my hair soon enough."

"So you're up to your old tricks again." Aqua realized.

"What is this, Sparta? I don't got time to toss around the old fire and brimstone." Hades said. "The whole cosmos is basically waiting for me to...you know...conquer it."

"Think you can actually do it this time? You weren't successful when you tried to use Cloud, Terra or Auron, so why's this any different?" Rainbow asked.

"Because this time… I've got these guys. Boys!" Hades called.

Suddenly the ground rumbled and thunder boomed.

"Crush...Zeus!" a large monster of rock said emerging.

"Freeze him!" a large monster of ice called sending cold winds out that were freezing all in its path.

"Melt...Zeus!" a large monster of lava said emerging from a mountain.

"Blow...him...away!" a large monster of wind said blowing away all in its path.

"It can't be… Titans?!" David asked.

"It's not just one, it's all four of them! Lava, Ice, Earth, and Tornado!" Hope gawked.

"They prefer rock and wind. Now...if you all would be so kind...get lost." Hades said as the Wind Titan sent the group flying. "Ah...smooth sailing….right to where I just left. Ah, oh well."

The Quintet was sent sailing to the town of Thebes. It wasn't better there, as the town was ruined. And in the town, Hercules, hero of heroes, was hard at work defending the town before hearing screaming when he jumped into action and caught the heroes.

"See...found him." Sora said.

"Well...I suppose this counts." Medusa said.

"Heh." Hercules said before they heard shouting as they looked up to see Donald hanging from a lion statue's mouth.

"Get me down from here!" he shouted.

"I'm on it." Medusa said as she jumped onto the statue to grab Donald.

Before she could reach Donald, something jumped before her and snatched him up.

"Seems y'all forgot something." a familiar figure said.

"Wait...Theo?" Hope said.

"Heh...Yeah...it's me." Theo said stepping out. "Hey everyone."

"Nice entrance." Eddy said.

"Thanks. Well, I could've stuck the landing a little better, it's just… new clothes." Theo said setting Donald down. "Oh, uh… sorry for stealing your thunder, Medusa."

"I don't really mind at all." Medusa said jumping down next to him. "It's been a while. Keyblade Wielder of the Zodiac."

"It has." Theo said.

"What're you doing here exactly?" Sora asked.

"See I've actually been doing intense training here in the Disney Heart Universe. Getting a better hang of my abilities. You know, stuff like that." Theo said.

"Really?" Donald asked.

"Yep. I've even gotten the hang of using magic now." Theo said.

"Well...nice to see all you guys again. Sora, Donald, Goofy, Dimensional Heroes and Shining Hope Squad. Even a few new faces. You all literally dropped in. Gotta say, I'm impressed." Hercules said.

"Hello." Ace said. "Oh right, Sora here wanted to ask you about something."

"That can wait. What happened here?" Sora asked referring to the ruined city.

"Give you a hint. Starts with an H." Hercules said.

"Ah, I get the picture. We actually ran into him, and he's the one who sent us flying." Hope said.

"With the force of a tornado, no less." Omnimon said.

"Said something about conquering the whole cosmos." Hagakure said.

"The whole cosmos huh? Well at least he's showing some self-restraint. Well, whatever he's planning, I'll send him flying across the Styx." Hercules said.

"That's our Herc!" Sora said.

"So Sora...as one of them was saying...why did you come here? Somehow I don't think it was for the cheese and olives." Hercules said.

"I have something to ask you. Do you remember the last time we were together? When you were down and out? How did you get your strength back...when you went to save Meg?" Sora asked.

"Hmm. That's tough. I just really wanted to save her with all my heart, but... it's not like I can tell you how." Hercules said.

"Company." Ace said as multiple fireballs were raining down.

"More heartless!" Hope said.

"Chili Pots seems to be what they're called." Mari said scanning them.

"Oh man, my first heartless encounter." Theo said summoning Zodiac Gate. "This is gonna be either nerving or fun."

"Just be calm and do what you do best." Aqua said.

"No worries. Aquarius Mode!" Theo shouted equipping his two water pistols. "And fire!" he said firing one that fired a larger stream of water than normal.

"Wow!" Donald said.

"Since learning magic...all of my keyblade forms have been improved!" Theo said firing more shots.

"Mind if I join in?" Ace asked.

"Nah, I got this." Theo assured firing and critically taking down the heartless. "And, done."

"You're pretty good." Hercules said.

"Hercules!" A voice called as everyone saw Meg and Phil riding down on Pegasus.

"Meg." Hercules said.

"Boy, that didn't look so fun." Meg admitted.

"Not with the heartless involved. We're lucky our friends showed up, but it was him who took care of this." Hercules said motioning to Theo.

"Hey. What's up?" Theo asked.

"Well, whaddya know? Guess I owe you a big thank you. And thanks for coming as well, everyone." Meg thanked.

"Meg...you should be somewhere safe. I can handle getting everyone away from the fire." Hercules said.

"You got it." Meg said as she and Phil boarded pegasus as he flew off with them.

"So, you guys wanna help out?" Herc asked.

"Yeah, you know it." Hope said.

"We're heroes!" Donald added.

"I'll come too. This is my wheelhouse." Theo said.

"Theo, you really don't need to." Hope said.

"I think I do. I know I'm not one of the Seven lights in this whole thing since I just have Sora's power, but I wanna help stop Xehanort. What am I if not a Keyblade Warrior?" Theo asked. "Besides...I still haven't shaken the guilt from when I was so easily tricked. I feel by doing this...I can finally shake free of these demons in my heart."

"Well...he is a little headstrong...but he's not that bad of a guy." Sunset said.

"Good enough. Come on then." Jexi said.

"All right then." Theo said.

"Also...there's a little girl in trouble and I can't get to them in time so...hope you all forgive me for this." Hercules said.

"Forgive you for…" Natsu said as they were tossed onto the fallen Hercules Statue before being sent flying. "Not again!"

Coincidentally, the statue landed near to where the girl was trapped allowing them to save her.

"Thanks for saving me." she said running off.

"Well...we did good...even if we nearly lost our lunch." Naomi said.

"Let's get back to Herc." Sora said.

"Well well...if it isn't Sora and the King's pawns as well as his other little...helpers." a voice said as familiar duo emerged from a dark corridor.

"Maleficent! And Pete!" Sora said.

"Why am I not surprised? Wherever there's heartless, you two aren't far behind. Did you summon them to help Hades?" Hope asked.

"Silence, whelp. We are not here helping him. I have my own matters to attend to." Maleficent said.

"Then why bother appearing before us?" Ace asked.

"Hey, I dunno about his sidekicks, but the keyblader ain't as hot as he normally is. I say we finish him off now while we got the chance." Pete said.

"No. We still have other matters." Maleficent said.

"Hmm. Oh! We gots to find that black box." Pete said.

"Silence you fool!" Maleficent said.

"You're looking for crashed airplanes?" Alkal said in confusion.

"As for all of you...we shall meet again...when I have time for such trifles." Maleficent said.

"Yeah. And you all better get your acts together before then. Later, twerps." Pete said as the two vanished into darkness.

"Well… That was something." David said.

"A black box… Hmm…" Naomi muttered.

"Black Box….is it possible they're looking for that?" Sheer pondered.

"So... that happened." Emo said. "We can handle those two later. Let's get back to Hercules."

"We'll have to get past these fires first. Don't think my Aquarius blasters will put the fire out, and we don't have time to extinguish the blazes." Theo said.

"Hmmm…" Goofy said holding his shield to the blaze. "Oh! Fellas, a crazy idea just hit me! Let's use my shield as a sled to slide over the blaze!"

"Problem. Your shield can't hold all of us." David said.

"Don't worry...I got a fun thing. Let's go! Capricorn Mode!" Theo said tossing his keyblade up before it came down as a giant shield.

"Alright, let's do the same, Donald!" Sora said.

"Yeah!" Donald said.

"Ready?" Goofy asked throwing his shield down as Sora and Donald got on. "Here goes!"

Both groups slid across the blazing stone as they saved multiple citizens across Thebes.

"And…gotcha!" CP said as he grabbed another citizen. "I believe that's all of them!"

"Yeah...looks like it." Hercules said having emerged from a collapsed building the others had helped him evacuate.

"My my my. Now that was quite a show." Xigbar said emerging from darkness.

"Go away!" Donald said.

"No Organization!" Goofy said.

"When you said we'd be seeing you again real soon, you weren't kidding Xigbar." Hope said.

"So you all did survive my surprise. Congrats. So, does having a heart of light come with a good insurance policy or something?" Xigbar said.

"What's your point?" Ace asked.

"I'm saying what I really mean. No good ever comes from putting others before yourself." Xigbar said.

"That's a lie, and you know it." David said.

"Yeah...I saved Meg from risking my life." Hercules said.

"But only cause you got friends in high places. Tricks like that don't work for your average joe." Xigbar said.

"You weren't even there when Herc did it. If you were, you would've loved his courage." Hope said.

"I'm not gonna start worshipping some guy who jumps into danger if someone else is gonna jump in and save him. You all are just lining up to lose out. Dooming others to take the fall with you. Oh...and you all can spare the usual party line. Yes, hearts are stronger when they're connected. But too much power in one place...some of those hearts might end up breaking." Xigbar said.

"What do you know about hearts? You gave up yours a long time ago." Issei shot back.

"But still...that doesn't mean you should change Sora. Accept the power you're given. Find the hearts joined to yours." Xigbar said.

"Why would we ever take advice from you?" Lemon asked.

"As if. You all have no choice but to follow this sweet little trail of breadcrumbs. And at the end, you'll find out what destiny has in store for you. Your reward is just around the corner. In fact, you're so close." Xigbar said laughing as he vanished.

"You know… Xigbar is just so charismatic, you just have some way to hate him." Hope said.

"Don't worry, Hope. You'll wipe that smug grin off his face soon enough." David said.

"I'm sure I will. But for now, we've got bigger problems." Hope said pointing to Mount Olympus where dark clouds were swirling over the top.

"It's Hades and the Titans, they've already climbed up to Olympus." Hercules said.

"We'd better get climbing ourselves." Theo said.

"Hmm… It looks like the non-flyers can use the gray surfaces to scale up the mountain." David said.

"I'll go ahead of you guys. My family on Olympus needs me!" Hercules said as he took off running.

"We won't be far behind!" Gray said as they followed him up to the mountains. But upon reaching them, the group felt the ground shake.

"What the?" Ichiro said.

"Titan!" Pinkie said pointing up to see the Rock Titan at the top.

"Crush...heroes! None shall pass!" He said tossing boulders down.

"Looks like Rocky's not gonna let us through without a fight!" Theo said.

"Then let's crush this oversized pebble!" Gohan said powering up.

"Go for his legs!" Hope called as they ran up the mountainside and went under the Rock Titans feet and started hacking away at its legs.

Medusa began charging up magic energy as a purple aura formed around her.

"Let's make things a lot more fun! Attraction...Flow!" Sora said as a rollercoaster materialized in the air as him, Donald, Goofy and Medusa got on board it. "Mountain Coaster!"

"Cool! That reminds me of ol' Big Thunder Mountain at Disney World!" Rainbow called.

"You think that's cool? Check this out!" Sora said as the coaster began firing shots of energy at the titan as it gathered it from the four riding it.

"Way to go, Sora!" Goofy called.

"Goku, Medusa!" Sora called.

"Right!" Goku called as he teleported to the titan's heads. "Solar Flare!" he called as a bright light blinded the heads.

A bright light engulfed the area as a whinny was heard as Medusa was on top of a pegasus. "As you command. I'll destroy you gently." Medusa said before she flew into the sky and came flying down with the speed of a shooting star. "Bellerophon!" She cried out as she pierced through the Rock Titan, creating a massive explosion.

"This is it!" Sora said hitting the titan with a barrage of fireworks.

"Kamehame…" Goku started. "HAA!" he called blasting the rock titan off the mountain.

"One down." Theo said.

"They're not so tough individually." Goofy said.

"Yeah. We actually might get through this better than we thought." Jesse said as they reached Olympus, climbing it before reaching the gates where Zeus was getting entrapped in magma and ice.

"I swear Hades...when I get out of this…" Zeus said before being fully encased.

"Sorry...but I'm giving the orders now, Bolt Boy." Hades said sitting in a makeshift throne.

"Hades!" Medusa called out as he turned to see the group ready to fight.

"You better not have gotten too comfortable yet!" Herc called flying up on Pegasus.

"Grrr...everytime….get them!" Hades ordered as the Ice and Lava Titans stepped up first.

"We've got this." Kurochi said.

"He's right. Leave this to us." Ross said.

"You go, Kurochi, Ross!" Hagakure cheered.

The Ice Titan starting firing ice missiles at the two while the Lava Titan fired a stream of lava from its mouth.

Ross swung his axe at the ground, creating a pillar that blocked the flow of the lava. He then jumped off the pillar and swung at the Lava Titan's head. Kurochi counters the Ice Missiles with his fireballs before firing a stream of fire of his own. Both struck hard at the titans heads sending them falling onto their backs.

"Come on! Don't let those runts push you around! You! Get in there!" Hades said as the Wind Titan joined the fray.

"This is where we tag out. You're up, girls." Ross said.

"You've got it. We'll handle this." Petra said as she and Kokoro stepped up. Kokoro breathed a stream of fire while Petra fired gales of her own. "Hera, now!"

"You will fall to my blade! Serpent's...Tail!" she shouted doing a zigzag sword slash making the titan fall over while also freeing Zeus from the rock prison behind her.

"Well….now this is something." Zeus said. "You kids have my thanks. Now...watch the old man work!" he said as he started hurling lightning bolts at the recovering titans.

Hope saw the titans running and saw the Wind Titan struggling. "Herc! Don't let em go!"

"I won't!" Hercules said grabbing the Wind Titan and used it as a vacuum to suck up the other three before tossing them into space before they exploded into stardust.

"Yay! Fireworks!" Ed cheered.

"I can't believe it! I put 18 years into that plan and you bipped it up!" Hades shouted. "I really don't like you."

"Feeling's mutual, hotshot." David said.

"You know what? Screw this. I'm just gonna go ahead and destroy you clowns!" Hades said.

"Hades." Hercules said. "The exit is that way. Oh wait...before you do…" he said punching Hades in the face. "That's for wrecking Thebes."

"And this…" Medusa started before using her daggers to send him flying. "Is for enslaving the gods." she finished before turning to Zeus as she bowed. "Lord Zeus."

"Glad our beef with Hades is finally over." Hope said.

"Yeah. Somewhere, I hope Cloud and Auron are happy we put him in his place." Aqua said.

"Terra too… don't forget Hades tried to use him." Rainbow added.

"Well...guess it's about time we headed on out. Not much left for us here." Hera said.

"Yep. Oh, and Hera?" David asked. "Now that I finally have a chance to say this… I'm sorry about the way I treated you before. I didn't mean to give you the impression that I was scared of you."

"Do not hold any ill will about it. I've heard and endured much worse as a slave in the coliseum. But fear...keep this in mind. Fear is only something that is born of ignorance...not of appearance." Hera said.

"That's certainly sound advice." Mark said.

"I've been wanting to apologize ever since I visited Eikichi's grave in Tokyo, but I never got the chance to." David said.

"Must feel great to say it now than later." Hope said. "And Sora, sorry you didn't get the answers you need."

"It's fine. I think the answers...are really something I need to find for myself." Sora said.

"May your heart be your guiding key." Ace said.

"Hey Ace… where in the world did you pick that phrase up from? Only Master Yen Sid knows it." Hope said.

"It's something he always says before we leave. I dunno where he could've gotten it since they haven't met." Goofy pondered.

"I'm not really sure…" Ace said.

"..." Naomi fell silent.

"Something up, Naomi? It's what Maleficent and Pete said about that black box, isn't it?" Sachiko asked.

"The Black Box...the Book of Prophecies…" Naomi said to herself.

"Hello. Olympus to Naomi." David said.

"Ah! Sorry. I got lost in my own thoughts for a moment there." Naomi said.

"You were just muttering something about a book." Mayumi said.

"Huh? I was?" Naomi said.

"What do you guys think?" Sachiko asked.

"The book of prophecies...it's been some time since I've heard of them." Sheer said.

"Do you think Naomi's case is just like Harumi's?" Petra asked.

"Yeah. During all the chaos of the tragedy, she may have been whisked away to one of these worlds. But… It's strange that she doesn't remember." David said.

"Hmm. Maybe we should go to the Mysterious Tower and consult with Master Yen Sid...he might know something that could help her." Goofy said.

"Good idea. We need to prepare ourselves for the journey properly after all." Hope said.

And so the company proceeded to leave Olympus for the Mysterious Tower.
