Hey everybody, I have returned with a new chapter of RWBY Hearts!

So Last time, our heroes saved Beast and Belle from Xaldin and Gaston, who had turned into Heartless. Now with that done, they are on their way to Olympus to see what Hercules is doing from the last time they saw him. Is he doing better or worse? Let's find out!

To RonaldM40196867: The heat of a demon is more like it. It depends on the furniture. Yes, he is. :) I saw Mickey in the death battle but not Sora. I like most of them; I just don't like it when they swarm you, which makes it difficult to swing at them. Nope. The world I often enjoyed the most was the Pride Lands.

To KnightSpark: I know, and it makes me feel bad :(

To Jacob9594: Xaldin always struck me as the most evil of the Organization alongside Xigbar and Xemnas. I'll consider those ideas, thanks :)

To Gamelover41529: It's the design from the mobile game Kingdom Hearts x.

To Robbery: I might because coming up with original ideas can be a bit too difficult and I want to get the story finished by the end of the year.

To Fallbridge: Thanks, and same to you :)

Kingdom Hearts belongs to Tetsuya Nomura, Shinji HashimoHashimotoy, and Square Enix.

Castle That Never Was/Arena

Blake was tossed to the ground by Saïx, who simply looked down at her. Blake then looked up and glared at him. "Where did you bring me?" Saïx just looked at her with an emotionless look, making the cat faunus glare at him. "Answer me!"

"Darkness will take hold of you." He said as he then vanished into the air. Leaving Blake annoyed and confused.

"What does he mean?" She thought as she looked around, this place seemed familiar…but she didn't know...hell she couldn't remember how long she had been trapped in this place. She wanted to get out so badly, she wanted to free the others, she wanted to find Ruby, she wanted Yang to-

Yang…Yang…as soon as Blake thought of the blind brawl, or the memory of her getting slapped across the face got to her, she felt the spot on her cheek that got slapped, and even though it was a while…the slap was still on her mind. All Blake could do was look to the ground and let a lone teardrop.

"Ow!" Blake looked up to see Yang had also been dropped by Saïx who disappeared as well. Yang angrily looked up to see that the man was no longer there. "WHAT THE HELL?!" She shouted, but alas, she was yelling right at the spot where the man was once at. "Shit…" She said as she got up and looked around and saw that she was back at the arena and sighed, but she then saw that Blake was there as well and she felt…conflicted to say the least.

A part of her remembered what her mirror-self said, and a part of her would never do anything to Blake…but the words of her mirror-self telling her to embrace the darkness were still lingering in her mind.

"Yang!" Blake said as she went up to her. "W-where are we?" She asked.

Yang glared but then rolled her eyes. "An arena looks like this." She said in a nonchalant voice. "However, Beacon's looks a bit better though." She said as she looked around.

Blake sighed. "Where do we go from here?" She asked. "I don't see any door." She said as she looked all around. "If only I can-" But her words fell on silicone as then all of a sudden, a group of Heartless nobodies began to surround them, making the two girls look at them with frowns on their faces. Luckily Yang still had her gauntlets and Blae still had her Gambol Shroud…wait…where did they come from?

Yang and Blake were a bit surprised to see that their weapons were still on them. But they didn't complain as they were now ready to fight them all on. Yang was still a bit unsure about being around Blake, but she knew that she had to push aside this feeling for the time being as she got ready. "Ready?" She asked Blake, with the cat Faunus nodding in agreement and the two of them began to fight

A large group of Dusks shimmered right towards Yang, but she was quicker as she used her weapons to punch and knock them all back, and due to her gauntlet containing bullets their heads were blown right off and caused them to vanish.

A group of Pirate Heartless came charging right at Blake, who had slashed the head right off a Fat body, and when she saw the pirates coming she quickly used her Semblance to vanish into a puff of smoke,e and to the pirates confusion, she appeared right behind them and delivered a swift kick and a slash of her weapons at them, causing their heads to come off as well.

Yang then dodged a belly attack from a Fat Body, and she delivered a strong uppercut right to the jaw, Blake used Gambol Shroud ribbon to wrap the Fat Body and swing it around and around, causing it to hit many other enemies and knock them all backward. "Come get some you ugly bastards! She said as her hair then went in flames and her usually lilac eyes turned red she charged right head first and began to hit every single Heartless in her sight.

Now when she was fighting them off, something inside Yang went off a bit. While a part of her was kinda glad to fight alongside her partner, another part of her was wondering why she was fighting with her…and that part was telling her to fight her instead! Could it be from her anger to her a while back? Or was it something else?

After what seemed to be a long while, all the Heartless and Nobodies were defeated and the two teen girls were breathing very hard. Blake then slumped down to her knees to catch her breath and then looked at Yang. "Are you ok?" She asked.

Yang, while catching her breath, looked back at Blake and even though she didn't want to speak to her…she sighed a bit. "Yeah, I'm alright." She said as she then got up and went over to Blake and extended her hand, but the action made the cat Faunus flinch and back up a bit, making the brawler look confused. "Blake?"

Blake didn't want to flinch, but her memory of that face slap was still on her mind and it made her a bit scared. When Yang put her hand out, Blake immediately thought she was going to be slapped and she didn't want to get slapped…not again.

At first, Yang was wondering why she was backing away, but then she remembered about the slap and a part of her felt bad…she didn't mean to hit Blake…but then again, a part of her felt like Blake des-OH WHY WAS SHE THINKING THIS? She didn't want to hurt Blake, not after all the times she was there for-wait..there for her-Blake ran away from her at Beacon, the events still playing in the blond brawler's mind and she glared down at Blake and she pulled her hand away and walked away, going over to sit down.

Blake looked at Yang's demeanor and a part of her felt bad…it was her fault, she made Yang like this! All she could do was hug herself and silently weep to herself.


Castle That Never Was

Unknowbest to the two, Luxord and Xigbar were watching through a screen. Xigbar had a frown on his face, while Luxord had a look of intrigue. "Yang seems to be starting to slowly lose her grasp on darkness," Xigbar said with a frown.

Luxord sighed as he got a card out. "All we can do is leave it to fate." He said. "So far she was able to channel it all, but it seems af is she is starting to lo-"

"Oh jeez," the eyepatched man groaned. "You and your prediction talk." He said as he also shook his head. "Well," He said. "Even if we lose our grasp on her..we always got Cinder."

"True, the powers of a Maiden could prove beneficial for us," Luxord said. "But what about Neopolitan?"

Xigbar snorted. "That ice cream-looking broad? She is merely temporary help, and once we get what we want, we turn her into a Heartless as well."

"No Nobody?" Luxord asked as Xibar raised his eyebrow. "Think of it. Her Semblance allows her to create physical illusions." He said as he put the card down on a table near him. "Imagine the possibilities that Nobody could do with it."

Xigbar then thought about it, and to give the man credit…it did sound like a good use. "I don't know what the boss would think. Besides, we need to get ready for when the Spring Maiden shows up." He said. "And it's only a matter of time before she does."


Underworld Entrance

The Gummi Ship parked right at the entrance to the Underworld, right where the steps leading to Olympus was and everyone stepped right out.

"I hope Hercules is doing better," Sora said with worry.

"I agree," Sun said. "That Hydra attack messed him up." Max was a bit confused, but he shrugged it off as he would be explained soon enough.

"Hey guys, look at that!" Ruby pointed at a large structure across the way from the entrance on the other side of the lake, everyone went over to get a better look.

"The heck is that?" Jaune asked.

"That's the Underdrome." Everyone turned to see Auron walk right up to them, they were happy to see him again, seeing as he looked to be doing rather well. "That's the Underworld's equivalent of the Coliseum up top. Zeus originally had it locked due to the senseless violence going on."

This made the team look at the Underdome in surprise. "But how did it get unlocked?" Stitch asked.

Auron shrugged his shoulders. "Some dumbass must've broken the seal."

Sora scoffed. "What an idiot." He said, with the others agreeing with him. Auron simply nodded and turned around to walk away, making the others look confused. "Wait, Auron!" Sora called out. "Why don't we catch up?" He asked.

Auron shook his head. "I got things to do. But if you want to, you should help your friends." He said.

"Sora!" The team turned to see Hercules and Meg standing at the stairs leading to the Coliseum, but when they turned back, they saw that Auron had vanished…where did he go? They simply shrugged, knowing that Auron could handle himself, and went over to Hercules and Meg, hoping that Auron would meet up with them again soon.

"Hey guys," Ruby said with a smile as they got closer. "How are you doing?"

Meg sighed. "Just the same routine, Wonder Boy thinks his hero days are over, and Phil thinks it's all in his head."

Ruby frowned and put her hands on her hips. "Herc, you know that the Hydra attack wasn't your fault." She said, but Herc just frowned a bit.

"Yeah!" goofy said. "We all know you're a true hero!"

"Ha." A familiar sarcastic voice said from the air. "That's right, Won-sorry-Blunder Boy!"

"Hades…" the Travelers of Light growled in anger as they had their weapons out, getting ready to fight. Then as if fate wanted to screw with them, the aforementioned god of the underworld himself appeared in a puff of smoke.

"I mean, how can you be so mopey-dopey on a day as momentous as this?" He asked as they all glared at him. "The Underdome is back and ready to be operated! And you are going to fill in the stands!" He said as he then approached them all. "Besides, all your fans who were tragically killed by the Hydra won't expect anything less from their favorite hero." Hercules glared hard at Hades as the god then wrapped his arm around the hero's neck. "I mean, if you're not up for it…well..you could always just lose."

Sora scoffed. "Yeah, I bet you'd like that!" He said.

"Yeah!" the other travelers said to him.

Hades scoffed at them. "Hey, I'm not a selfish guy, you know. I'm not like those high and mighty snobs on Olympus." He then looked back and looked directly at the camera. "Especially if you consider how they act in the original mythos." He said with a wink as he turned back to Sora and the others, much to their brief confusion. "I happen to stand for the masses, and boy, do I have an idea that's massive!" He said as he turned around. "Pain, Panic!" He said to his two imp minions.

'I want to declare that the games are back in session!" He said with enthusiasm. "Hosted by yours only, Hades the God of the Dead!," He said as if he was announcing an event for all to hear and see. "I bring to you the ultimate games, to celebrate the re-opening of this glorious coliseum!" The heroes simply gagged at that statement. "And, we will finally answer once and for all…who deserves the title of 'Ultimate Hero'" Hades then looked over at Hercules, who was just looking at him with a glare. "And I assure you that the great and mighty Herc will be there as well…or else." He said as he pointed his long finger in Meg's direction. "You'll never see your girlfriend again." He said to Hercules, making the man glare hard.

"We're not going to let you do anything to her!" Jaune said with his sword out.

Ruby nodded. "Bring it on, you overgrown flamethrower!" She exclaimed.

Hades chuckled and glared at Ruby. "Believe me, Red…I will." He said with a dark smirk. "You will be partaking in the ultimate cup. The Hades Cup! Named after yours truly." He said with a smile as he then disappeared in a puff of smoke.

"Damn, lowlife!" Sora said.

"Awe, you're way to kind kiddo." Hades's voice said to him, making all the heroes glare.

"All of you, come here!" They turned to see Pain and Panic over by two small boats and they all approached. "Now her; 's the deal. If any of you wish to partake in a tournament, talk to me!" Panic said to them.

Pain nodded. "His Most evilness is feeling charitable, so don't worry about tying or anything." He said with a smirk as he and his fellow imp snickered.

"You little-" Donald had to be held back by Oswald from doing something he might regret.

Pain also pointed his thumb to himself. "I will register you all for the Hades Cup, don't go to Panic for that, he is in charge of the other tournaments."

"Feel free to enter any tournament if you wish!" Panic said. "You get lots of cool prizes." He said with a smile.

Sora and the others looked at eachother, this wasn't how their second visit was supposed to go...but if it meant helping Hercules get back on his feet then they felt like they had to do it. "Alright, sign us all up for the Hades Cup." He said as the others nodded in agreement.

After signing up, they all went to another board to see just how much of the Hades Cup they would be doing, and there were quite a few in there. "It seems the first team we are going up against is called..the Spin Strike?" Ortensia asked with confusion.

"Reminds me of the cups we partook when we were here the first time." Sora said, with Donald and Goofy nodding in agreement. "Oh look!" He said, getting everyone's attention. "Aurons in the tournament as well!"

"I guess that means we're going to have to fight him eventually…" Jaune said with caution.

Hercules looked at the name and gave a small smile. "He sounds like a real hero, huh?" He asked them, and that made the group ponder a bit.

"I'm no hero." Auron's voice was heard in their minds after meeting him the first time…was he a hero? They don't know.

"Well, he isn't a bad guy…" Ruby said with some uncertainty in her voice. "But still, the only hero around this place is you Herc."

"She's right, dude!" Sun said with a smile.

Hercules looked at them all and smiled a bit. "Thanks guys…" He said


Underdome

The Travelers of Light and Hercules were all led to a large area, which seemed to be one big circular block, the ring being surrounded by emptiness, and they all looked up to see many deceased spirits in the wings cheering and applauding.

"Ok..this is a bit weird…" Max said as he gulped nervously. The group app made it and stood on the other side, with the bridge between them fading away.

"Ladies and gentlemen of the dead!" Hades's voice called out from the air. "I give you, the HADES CUP!" He said, which was met with applause from everybody, the heroes raised eyebrows at this. "Please god, your applauds. For the first match, we have the Boy Wonder himself Hercules, and his stooges facing off against many Heartless! For the first round, we have the heroes against the Spin Strike!"

At that moment in puffs of smoke, a group of Heartless appeared. One of them was a Morning Star, two Driller Moles, three Tornado Slaps, and three Bandits. Also, there were three Fat Bandits, and three Air Pirates, The heroes all looked with determination and got ready to fight.

"Alright! LET'S RUMBLE!" The crowd cheered.

The Morning Star bunched up in an attempt to squish the heroes, but Hercules glared and jumped up. "Try squishing this!" He exclaimed as he reared his fist back and delivered a strong blow right to the Heartless, causing it to crash right down to the ground and land with a loud thud, while also causing the other Heartless to scatter.

Sora and Oswald ran toward a group and threw their Keyblades. "Air Raid!" They shouted as their blades struck two Fat Bandits, causing them to go backward a bit, and as the two went back, they saw Sun swinging his staff and giving a good swing, causing the two to go flying out of the arena and into the dark abyss.

Stitch grabbed hsi blasters and fired several lasers at the Tornado Slaps, causing them to get zapped to oblivion, he then noticed an Air Pirate coming down at him and he quickly jumped out of the way in time. "BOOM!" He shouted as he fired the rounds at the pirates as well, causing him to laugh.

Hercule ran towards the Morning Star and swung him around, and around, and around until he threw him up in the air and jumped once more. "Take this!" He said as he cupped both fists and slammed down super hard, causing the large Heartless to call on the arena one more, and this time it didn't survive the impact. The audience roared with cheers.

"And give it up for Wonder Boy and his comrades!" Hades' voice shouted in the air, making the deceased cheer. "No big surprise there…" He muttered, much to ire of the others.

"We heard that!" the heroes shouted.

"Yea, yea, anyway, now we take you to the next seed. Which I like to call, BAD ALERT!" He shouted as more Heartless appeared. This time it consisted of three Pirates, three bandits, and a swarm of Hot Rods. The heroes all glared hard at the Heartless as they got ready for another fight. "If the heroes win, they then move on to the finals!" Hades shouted. "Now rumble!"

The Hot Rods honked their horns as they revved up and went at the team in super speed, causing a majority of them to dodge out of the way, but had to be careful so they didn't accidentally fall out of the arena, but it also didn't help that the Pirates and Bandits were swinging their swords all around…how were they going to get out of that one?

BANG

Jaun flew back to a thud after being hit by a Hot Rod, luckily he had his shield but the impact was still pretty powerful. Jaune then got up and looked all over and thought of something. "If I get the others to distract these things, they might push eachother out of the ring." He said as he then saw a Hot Rod coming at him once more, using his quick thinking, he waited till the hot rod came dangerously close, and ten right at that moment, he quickly dodged out of the way, causing the Heartless to go right out of the arena. Jaune looked and smirked and he turned his attention to the others. "Guys!" He called out. "Try to either get them to run eachother out of the ring or into each other!" He called out.

Sora looked at Jaune and he nodded as he saw two hot rods coming at him as he then quickly dodged right out of the way in time, the Bandits that were right in front of him weren't so lucky as the Hot rods ran right into them, causing them all to go right out of the arena.

Ortensia smirked as she then pointed her wand at the ground. "Ice!" She exclaimed as he then covered the ground in ice, causing the Hot Rod coming at her to skid out of control it wasn't the only one, the other Hot rods were skidding crazily as well as they all ended up crashing into each other and other Heartless, causing them all to die in explosions.

The heroes were once more victorious, with the undead cheering for them once more. "And once more we got Hercules and his stooges as the victors!" Hades's voice said from afar. "I still can't believe it…" He muttered. "Alright folks, We're going to be taking a brief intermission!" He said, making the undead cheer once more.

Sora looked around and saw Aurn nearby looking at them all, Sora waved but for some odd reason, Auron didn't wave back…in fact…he seemed as if he was in some sort of trance. Auron turned around and walked away, making the Keyblade wielder confused and concerned.

"Auron?" He thought.


And we are going to stop there folks! I hope you are all enjoying it!

Now I got a comment a while ago saying that Pyrrha should be in this part to give Jaune some closure, and I'm not doing it, I think it's still early for Jaune to get closure, don't worry, he will get it but not just yet.

Now for the other Underdome tournaments…will I do them? Maybe..I don;t know, if I do maybe I'll do a spin-off fic.

Anyway please don't forget to read and review, I'm always happy to hear from my uo guys and happy to answer any questions you might have for me.

See you all next time as we get to the final of the Olympus Coliseum :)
