BGM: Dragon Roost Island (The Legend of Zelda: Wind Waker)

Worldwalker was in his own room of the Blue Typhoon, chuckling to himself. "Yes, YES! This is brilliant!" He exclaimed. "This is amazing!" He laughed as he walked out of his room and ran off.

He then got into the cockpit to see the Keyblade Wielders just hanging out there. "Guys!" He exclaimed.

"Hmm?" Nan turned his head. "You seem giddy over something."

"Summon gems!"

"For all of us?" Julia asked.

"Um, not you…unfortunately, I couldn't think of anything to aid you since well…you got the mercenaries and Lana." He admitted.

"Oh…okay." Julia shrugged.

"Anyway, these are for you!" He said as he also gave one to Rose.

"Oh, for me too?" Rose asked.

"Yes." He nodded.

"Let's see who I have!" Isaac exclaimed as he raised his up in the air, and then Chrom appeared in front of them.

"Hmm?" Chrom turned his head. "Where am I?"

"Whoa! Chrom!" Isaac exclaimed.

"My turn!" Nan called his up, and then Henry appeared.

"…How did I get here?" Henry wondered.

"I'm next!" Flare said and then she summoned Lissa.

"Huh?" Lissa looked around. "What's going on…"

"I'm sensing a theme here." Tristina said, looking at Worldwalker.

"Yep, Fire Emblem." Worldwalker said as Tristina called hers up, and then Virion arrived.

"Interesting…" He said and then spotted Minene. "Oh, my sweet dear maiden!" He said as he got in front of her. "Where have you been all my life?" He asked.

"Excuse me?" Minene blinked, and then Chrom pulled him away.

"This is not the time." Chrom said.

"…Random." Minene blinked.

Kai called hers up and then Vaike appeared in front of them. "Alright, who do I have to start chopping down with my axe?" He asked.

"That's…scary." Rose sweatdropped.

"Let's see who I have!" Hina exclaimed, and then the Ragnell impaled the ground in front of them and then Priam pulled it up. "Shoot…I was thinking I had Ike for a second there."

"So you know of my ancestor." Priam grinned. "My name is Priam, the Radiant Hero."

"My turn!" Maria exclaimed and called hers out, and then Kellam appeared.

"Um…hi?" Kellam said.

"Hi!" Maria waved and then finally, Rose summoned hers, and then Robin appeared in front of them.

"Hmm?" Robin looked at them and then at the others. "Uh, Chrom, do you know where we are?" He asked.

"I'm afraid not." Chrom answered as Worldwalker brought them up to speed about the situation. "You don't say…"

"We'll be more than happy to assist you." Robin said and then knelt down, patting Rose on the head, causing Rose to smile and then they all disappeared.

"Well, that was very interesting." Knuckles said.

"Except that there's a hole in the floor now…" Tails sweatdropped.

"Uh, sorry about that." Worldwalker said. "Anyway, that's all I just wanted to give you." He said.

"Uh, guys?" Amy got their attention. "I'm picking up on a huge ship approaching us!" She exclaimed.

End BGM

And right on cue, the huge ship approached them from behind, until it was right next to the Blue Typhoon, it was the main Metarex ship! "What the heck is that thing doing here?" Nan asked.

Suddenly, they heard a voice. "Well done, White Seed. Your mission is complete."

'What? My mission...' Cosmo thought. 'White Seed... White... Seed' That is when she began to remember.

BGM: Metarex Theme (Sonic X)

The Metarex was attacking a ship, one that Cosmo was on. She ran, trying to find a way to escape, with only one thing in her mind.

"I don't want to die."

But it was no use. The Metarex had found her, but they didn't kill her. Instead, they did something else.

"Listen to my voice, and take my hand."

End BGM

That was all Cosmo remembered as she the voice of Dark Oak continued

"Take my hand, listen to my voice! Your eyes will be mine, and your ears will be mine!"

It was obvious to her now; she was a spy for the Metarex! Realizing what she had done, she screamed, and her amulet began to shine as the whole place glowed.

"What the heck?" Nan exclaimed as the Blue Typhoon and Dark Oak's ship was enveloped by a bright light, blinding everyone.

Everyone eventually came to as they looked around. "Where are we?" Isaac asked.

"I think…we're in some dead planet." Minene said, pointing outside as they all looked to see dead trees everywhere.

"My God…" Suzaku whispered, horrified at the site.

"Are there any survivors or anything?" Anya asked.

"Let me check…" Amy said as she scanned the area. "Nothing…it's a barren wasteland."

Yuno shuddered. "Something about this place rubs me the wrong way…"

"Easy now, let's not get too insane." Minene said.

Shadow, however, angrily walked over to Cosmo, who was knocked out and in Tails' arms. It would seem that figured out Cosmo's role as a spy. "Stand back." He growled as he aimed his hand up, ready to use Chaos Spear on her.

"What are you doing?!" Tails exclaimed.

"Taking care of a problem."

"Shadow, don't!" Professor Jacob attempted to stop him.

"Why shouldn't I? She's been a spy all along…" He growled. "If we don't do something, the Metarex will gain the upper hand!" He aimed his hand at Cosmo.

"Shadow, remember what you promised Maria?" Jacob asked, causing Shadow's eyes to widened and flashbacked to when Maria was still alive.

"Promise me, Shadow…that you won't kill anyone…why you're down there…you're not a monster, but a very good friend…"

"Maria!"

Shadow snapped out of it and growled. "Fine…" He said as he turned around. "But how are we just going to let this slide?"

"She unwillingly became a spy without even realizing it." Professor Jacob told him. "But we will have to do something, and quick."

BGM: Hidden Land (Pokemon Mystery Dungeon: Explorers of Sky/Darkness)

Later…

Cosmo was on a hospital bed and Tails seemed to be working on something. "There's nothing here that shows anything about Cosmo being a spy." Tails said.

"Hold on a second…" Nina said. "There's probably something more than meets the eye here." She said as she typed something in Tails's computer and then to their amazement, there was a little tiny microchip undetectable my regular computers, until now. "Aha!"

Tails looked at it and clenched his fists. "Let's remove it."

"Whoa whoa whoa, bad idea." Chris said. "If we do that, that'll just make things worse. You see, it's in the part of her brain that connects to her sight and hearing, if we remove that… she might lose her sight and hearing." He said, causing Tails to frown and feel sad.

"Then it's a risk we have to take." Knuckles said.

"What?!" Tails exclaimed. "We can't do that!"

"Then what are we supposed to do? Keep going on with our lives with Cosmo while the Metarex are one step ahead of us?!" Knuckles asked, causing Tails to glare at him. "I'm not trying to be the bad guy here, but if Cosmo continues to have that inside her brain, then the Metarex are one step closer to annihilate us all."

"I'm with Knuckles." Nitori said. "It's a risk we'll have to take."

"Tails…" Nina knelt down to his level. "I don't like this either, but we have to do something or else we'll be killed by the Metarex."

"Am I the only one here who thinks this is a bad idea?" Chris asked.

"You're not, but just leave it to me." Nitori said. "This might take a while though…so, its best not to rush into things."

"Come on, Tails…let's leave her alone." Knuckles said as he pulled Tails away so Nitori could do her work.

"I may need some help on this, though." Nitori said, looking at Nina.

"I'll do anything I can." She said as Nitori nodded.

End BGM

A few hours later…

"Mmm…" Cosmo woke up and Nitori and Nina were looking at her.

"Do you think it worked?" Nina asked.

"Let's see." Nitori said. "Cosmo, how many fingers am I holding up?" She asked, holding up three fingers.

"…Three." Cosmo said.

Nitori grinned. "It worked!" She exclaimed as she high fived Nina.

"Wait, the microchip is out of me?" Cosmo asked.

"Yes, you can see and hear like normally!" Nina smiled.

Cosmo grinned. "Thank you!" She said and ran off, searching for Tails as she eventually found him. "Tails!"

"Hmm?" Tails turned her head. "Cosmo…was it a success?"

"It was." Cosmo smiled as Nitori and Nina came by and gave them a thumbs up.

Chris sighed with relief. "I was worried that it'd end horribly."

"See? I told you everything would be fine." Knuckles said.

"Hmm?" Nitori looked around. "Where's Shadow?"

"Getting some fresh air." Sonic replied. "The guy wanted some time to think after finding out about Cosmo."

"I'm sorry…this is my entire fault." Cosmo muttered. "Had I known I was a spy, I wouldn't be here…"

"It's not your fault." Isaac said. "It's the Metarex's fault." He said and then smirked. "Heh, it gives me another reason to beat them up."

"Uh…don't you mean 'we'?" Tristina asked.

"Yeah." He nodded when Sakuya appeared in front of them.

"Um, Shadow and I have found something." Sakuya said.

"You have?" Sonic asked.

"Yes, follow me." Sakuya said as she flew off with everyone following until they came to a facility.

In the facility...

"What is this…?" Hina asked.

"It used to be a civilization of some sort." Shadow said. "This is all that's left." He said as an image of a person that looked like Cosmo appeared in front of them.

"Did this happen before you came over to us?" Komachi asked.

"No." Sakuya shook her head. "This is the first time we're seeing this."

"If you are seeing this, then do not be alarmed…but we have left our planet for it has been destroyed by the Metarex." The woman said. "Long ago, we used to be a civilized people until war struck. We were constantly being killed until enough was enough, so we decided to leave."

"Huh…" Isaac said.

"However, there was one person who was against the idea…his name was Lucas and he rallied many of our people to keep fighting and turn themselves into monsters. It was his dream to restore our planet, but it was too much for us, we had to flee no matter what. The ones who fled had no choice but to bomb the rest of the planet, including the ones who chose to stay. We thought we eliminated them, but only five survived, turning them into what we call the Metarex, their leader is Lucas…who is now named, Dark Oak."

"Dark Oak?!" Flandre exclaimed.

"Quite the history lesson, isn't it?" A voice asked as they turned to see Dark Oak who looked like he was standing there the whole time. "Yes, it was I who did this." Dark Oak said. "I had a dream to take back our planet, but that fool Earthia didn't see it. In the end, we Metarex destroyed them…all, but one." He said, glancing at Cosmo.

"Why would you do this?!" Cosmo asked.

"Every single one of them was a fool for not seeing the dream that I had." Dark Oak replied. "But never mind that, I will need that Chaos Emerald you have."

"Dark Oak, answer me! Why would you go out of your way to kill my mother, father and my sister, Galaxina?!"

"…Your father is still alive." Dark Oak said.

"That can't be true, you murdered him!"

"No, Cosmo. I AM your father." He said as Cosmo's eyes widened in shock.

"You did this to your kind?!" Minene exclaimed, pulling out her gun. "What kind of sicko does that…not to mention all the hell you've put your daughter through!"

"I've done it for a very good reason…to destroy all those who oppose us. We've listened and we've seen everything that she's seen and heard. Why else have we been able to ambush you and do anything we can to stop anyone that would threaten us?" Dark Oak asked.

"Don't you realize there were countless times you've put your daughter in danger?!" Suzaku exclaimed.

"Her mission would've been completed if she was destroyed in the process along with the likes of you." Dark Oak said.

"You little…" Yuno growled. "That's uncalled for!"

"I think we need to teach you a lesson." Isaac growled as they all got ready for battle.

"Go ahead and try." Dark Oak challenged.

BGM: Vim and Vigor (Kingdom Hearts II)

"Let's go!" Komachi exclaimed as she flew over to him with Sakuya and slashed him several times, but he dodged every attack and kicked them away, where Suzaku ran over and did his spin kick on him, but he blocked it and punched him away where Gino did the same thing.

"Fool." Dark Oak said, kicking Gino away as he was hit by a couple of kunai knives by Sayoko and Espio, but he simply chuckled as he pulled out some sort of sword and slashed the two of them away, and then he was hit by a box from Silver while Blaze unleashed a fire stream at him, where Buru was behind him and used Fire Spark on him, and then he ran over and slashed Blaze away where he kicked away Shadow who was spin dashing towards him.

Shadow growled. "Chaos…BLAST!" He yelled, knocking Dark Oak a few feet where he was then punched by Knuckles, but he grabbed his fist and threw him to the side and then he was attacked by Flandre using the Lavatein spell, but he ducked and used an uppercut on her, and then the ground beneath him blew up while Minene came up from underneath.

"Hmph." Minene smirked, but then Dark Oak appeared behind her and kicked her away.

"Aunt Minene!" Rose exclaimed as she raised her hand up and called up Samurai Prowl as he ran over and slashed Dark Oak away where Maria Jr screamed at him to knock Dark Oak to a wall.

"Hmph…" Dark Oak teleported to them. "Impressive." He said and then he was hit by Rouge's piledriver kick with the help of Charmy, Cream and Tails, but they were knocked away as he was hit by a Dark Firaga spell from Isaac as Yuno ran to him and slashed him several times, but he blocked every attack. "So, you're the famous yandere I've heard so much about."

"Hmph, so you've heard of me?" Yuno asked.

"Indeed." Dark Oak nodded. "It's interesting to see you up close and personal, it's quite interesting to see how predictable you really are."

"That's not going to work on me." She said.

"Then what if I told you…that after Xehanort has been defeated and you had joined those Keyblade masters…we came to your world and obliterated it?"

"What?!" Yuno exclaimed.

End BGM

"That's right, not a single ounce of it remains. You and that bomber are the only ones left of that world."

"You're telling me…you got rid of it?!"

"Indeed. Nothing left of it exists, your friends, family, everything you held dear…" He said. "It's gone entirely."

"No…" Yuno growled. "I…I wanted to see Yukki's grave one last time…"

"He's gone too…he's nothing anymore. He was a waste of breath in this cruel universe."

"Shut up…" She said, clenching her fists.

"Yuno…don't go there!" Minene said.

"Need I continue? Everything is gone, all that you cherish? Non-existent anymore. Your friends and everything you cherish…is no more. Heh, it's no surprise…that world was pathetic anyway."

"You shut up…" Yuno said. Her breathing had noticeably changed, and her eyes were changing as well.

"Yuno!" Minene called out, but her voice was fading, she could only hear herself, and Dark Oak.

"You…are a weakling." Dark Oak said.

"I…am not…" Dark aura shot out of Yuno. "A WEAKLING!" She yelled.

BGM: Stand Up Be Strong (Bleach)

Yuno screamed maniacally as she ran over and slashed him several times. "At last, the true yandere has awakened." Dark Oak said as he blocked every attack and sweep kicked her, but she quickly recovered and kept attacking him.

"A-Aunt Yuno?!" Rose exclaimed in shock and horror.

"Don't you worry; I won't let her get to you." Minene said, getting in front of Rose.

"RAAAAAAGH!" Yuno yelled as she kept attacking him, but blocked every attack with his sword.

"Is that the best you can do?" Dark Oak asked as he kept blocking every attack until he punched her in the gut, causing her to cough out blood and then he kicked her to the side. "Hmph…I'm disappointed."

"I'm not done yet….YOU HEAR ME?!" Yuno yelled. "I WILL NOT REST UNTIL I KILL YOU!" She screamed as she ran over and slashed him again, but this time she kicked him and then slashed him while he was momentarily stunned.

"Your attack style is interesting…" Dark Oak said. "All you do is slash with that katana sword of yours and rarely do you ever change attack patterns." He said. "That's…very disappointing. I was hoping more of a challenge." He said as he grabbed Yuno's katana and yanked it from him.

"You dirty little…!" Yuno growled as she pulled out her knife and went to attack him, but he kicked it out of Yuno's hand.

"Your back up is but a mere knife…how amusing." He said as he looked at the katana sword. "This sword has seen better days…" He said. "Time to put it out of its misery." He said as he basically snapped it in half, making Yuno's eyes widen.

"That's it…I'M GOING TO KILL YOU!" She screamed and ran over to punch him, but he blocked as he then flipped her over and then punched her straight to the ground, and then placed her foot on her.

"You are not that all cracked up to be." Dark Oak said as he put his sword to her neck. "In fact, I've half a mind to end your miserable life…but no…that's too easy." He said he put it away as he grabbed her by the throat. "Get out of my sight." He said and threw her to a wall, knocking her out.

"Dark Oak, we have the remaining Chaos Emerald!" Pale Bayleaf's voice echoed.

"Good. I will meet you there." Dark Oak said as he looked at them.

"This was just a mere distraction?!" Shadow exclaimed.

"Indeed it was. We will meet again…but this time, you will not be so lucky!" He said as he disappeared.

End BGM

"Remind me to bomb his entire ship once we're done with him…" Minene growled, but Rose was more fixated on Yuno.

"Aunt Yuno…" She said, tears falling from her eyes. "W-was that…the real you?!"

Meanwhile…

"Dark Oak, we are ready to move forward." Black Narcissus said.

Dark Oak nodded. "Well Earthia, it seems your daughter has decided to continue in your mother's footsteps. But I'm afraid she is just as misguided as you." He said as he looked at the Chaos Emeralds in front of him. "All of the lights have been gathered, the time has come, the forestation project is about to begin!" He exclaimed.

Dark Oak sure knows how to piss people off, especially if it's Yuno.
