"Nnngh…" Xena fell on one knee, wincing.

"Is that all you can do?" Mewtwo had his arms folded.

"N-no… I can do this…" Xena got back up, panting.

"I don't think this is a good idea." Lucario said with concern.

"She has to be one with her dark side. If she doesn't, then there will come a day where she will fully lose herself and it will be next to impossible to get her back." Mewtwo said and looked to Lucario. "Isn't that what you told me from what Ozpin relayed to you and Robin?"

"Yes, but are you absolutely sure this is a good idea?"

"Do you have any better ideas?"

"Well, no, but-"

"Then this is the only way." Mewtwo said and aimed his hand at Xena. "Now… again!" He closed his hands, using Psyshock on her

"Nnngh… AAAAAAAAAGH!" Xena screamed, holding on to her head while nearby, her teammates were watching.

"This is just hard to watch…" Nyx sighed.

"I feel like there's a better way to treat this, but no, Mewtwo had to step in to try and get her to become one with herself." Jade muttered a bit.

"Well, if it's the only way… though I have a feeling this might have a negative effect on her." Iris mused. "…Nah, probably not, but why attack her mind?"

"Maybe Mewtwo sees something that we don't?" Jade wondered.

Mewtwo lowered his arm as Xena fell on both knees, tears coming out of her eyes. "I, too, know what it's like to fully lose yourself in rage. I know what it is like to become a monster. Seeing you lose control of yourself over explosions made me realize that you are running out of time before there is no going back. You are a ticking time bomb, and I personally believe it is time for someone to step up and make you become one with your dark self. You agreed to this."

"Nnngh… y-yeah… but I had no… no idea this… this would be painful…" Xena groaned, panting.

"There is no other way." Mewtwo said. "It is time for you and your dark side to become one. Be one with yourself. Use your weapon to your full potential!" He declared, aiming his arm at Xena again. "Again." He unleashed Psyshock on her.

"KYAAAAAAAAAAAAH!"

"ALRIGHT, STOP!" Nyx yelled, getting in front of Mewtwo and spreading her arms out, forcing Mewtwo to lower his arm. "Can't you see she's suffered ENOUGH mental trauma?! It's bad enough that she had lost everything in that war and had become a different person, but do you honestly think using Psyshock on her would make things better?!"

"Hmph. If you have another suggestion, I'm open to it." Mewtwo folded his arms.

"I…"

"You do not have anything."

"Well, if you would just let me think, I'd come up with something!"

"N-Nyx… it's… it's fine…" Xena whispered, struggling to get up but her strength was failing. Jade, Iris and Pikaboo quickly came to her side.

"Easy now…" Jade said.

"Xena, you're not fine. This is taking a toll on your mental health!" Iris exclaimed. "You can't keep going like this!"

"Kyu! Kyu!" The Mimikyu agreed.

"I… I'm fine…"

However, Xena collapsed from exhaustion. "Xena!" Jade yelled.

"She's weak." Mewtwo grumbled. "I am only trying to make her stronger."

"By attacking her mind?!" Nyx yelled.

"It is the only way. As far as I'm concerned, she is at constant war with herself and as I see it, her dark side is winning. What would you do if she kept losing control of herself? Would you let it happen or would you do something about it?"

"We'll do anything to keep her calm." Nyx told him. "She's our friend… our teammate! We'd-"

"If you're her teammate, you would immediately seek assistance and put her into therapy or send her to someone who can teach her to be at one with herself. The way I see it, you three just let it happen and you don't do a thing when she loses control. She is weak, she needs to be stronger. All of you go about your day as if nothing is wrong while Xena is suffering from her mental condition. In my eyes, none of you are good friends to her."

"That is not true!" Jade yelled.

"You may be defending her, but this is how I see it." Mewtwo turned around, his back facing all of them. "There will be a time where she will lose full control of herself and nothing you will do will bring her back. If that happens… the only choice will be to put her down."

Iris's eyes widened. "What?! No! We won't do that to her!"

"Are you out of your mind?!" Jade yelled.

"That's enough out of you!" Lucario yelled, glaring at Mewtwo.

"Mewtwo… what if you're wrong?" Nyx glared at him, forming a small scowl.

"Hmph, I welcome you to try to prove me wrong should the time comes. We resume her mental training as soon as she wakes up." He said and then floated away.

"Asshat." Iris spat.

"Come on, we need to get her to bed." Jade suggested.

"You guys do that, I need to go do something." Nyx said and then walked off.

"And where the hell are you going?" Iris asked.

"On an errand. I'll be back."

Jade sighed. "Why did he have to say all those things."

"You have to forgive Mewtwo… he's not exactly the most easy to talk to." Lucario said and then turned his head toward Mewtwo's direction. But why do I have this feeling that he might be on to something?

Meanwhile…

BGM: Angry Aztec (Donkey Kong 64)

The gang walked out of a cave to see that they were now in a desert. "Oh… a desert." Ruby said.

"Oh great." Blake groaned.

"Something the matter?" Banjo asked.

"Yeah, we always run into someplace hot every so often in another of our crazy adventures." Ruby explained. "Not to mention she's wearing dark clothing."

"It's just my luck!" Blake sighed. "We either go into a desert or a volcano… and I had this dream where we were searching for these Star Spirit things in a desert and a volcano! The crazy thing was that we were made out of paper!"

Ruby looked at Blake with a raised eyebrow. "What kind of fish have you been eating before bed?"

"I don't know! It was the weirdest dream…" Blake rubbed her head. "Well, at least I don't have it as bad as you and the Kongs. You must be roasting with that fur."

"Naw! I'm fine." Banjo said with Donkey Kong and Diddy also giving them a thumbs up.

"Okay, what about Kazooie? She's probably roasting in that backpack!"

Kazooie popped out of the backpack and pulled out an air conditioner. "This makes the backpack at a comfortable temperature!" She said and then went back in.

Blake sweatdropped. "That makes… as much sense as what Link keeps in his pockets."

"How deep are his pockets anyway?" Ruby asked.

"Deep as Kirby's stomach, probably." Blake shrugged as they walked through the desert. "Hmm, come to think of it, the desert isn't so bad as the ones in the Mushroom Kingdom." She mused.

"Plus, this one doesn't have an Angry Sun trying to kill us!" Ruby pointed out.

"True." Blake nodded. "I wonder if we'll find any of our friends here?"

"I'm sure we will!" Ruby smiled, and then noticed a hut nearby. "Hmm? What's that over there?"

Blake took a closer look. "Candy's Music Shop?"

Donkey Kong immediately snapped to attention as soon as he heard "Candy" and then he ran over to the shop, with Diddy right behind him. "Huh, guess he likes candy? Wonder if they make candy bananas?" Ruby wondered.

"I don't think it's that type of candy."

Banjo chuckled. "Oh, it's something else entirely." He said as they walked to the music shop.

Pause BGM

BGM: Candy's Music Story (Donkey Kong 64)

Donkey Kong ran in and saw a tall, slender, blonde Kong walking into the room, doing a few poses and showing off her… ahem… assets… and gave Donkey Kong a flirty wink as Donkey Kong let out some gorilla noises with hears replacing his eyes and pounded his chest while Diddy did a 'sup' nod at the female Kong… and then Ruby, Blake and Banjo walked in.

"…Sweet mother of Oum!" Ruby jawdropped.

"Whoa… I… wasn't expecting that."

"Oh… Banjo, is that you?" The Kong spoke. "I haven't seen you in ages!"

"Heheh, been a while, Candy!"

"That's Candy?!" Ruby quietly mouthed, watching the two hug.

"Where have you been? I've heard rumors that you were into kart building these days."

Kazooie popped out of the backpack. "We're trying NOT to remember those days, thank you very much!"

"Oh, hello Kazooie." Candy giggled and then looked at Ruby and Blake. "Oh! Who are these lovely girls?"

"Uh… I'm Ruby Rose and this is Blake Belladonna!"

"H-hello!"

Candy smiled. "So, you're the famous Team RWBY that Donkey has told me so much about. Now that I know what you look like, I guess I don't have competition."

"Competit… wha?" Ruby tilted her head.

"Don't worry about it, honey!" Candy giggled again, then turned back to Donkey Kong. "So, what can I do for you? Do you mind if I… tune your instrument up?"

Blake's eyes widened and quickly covered Ruby's ears. "You don't need to hear this!"

"Ack! Hey!"

Donkey Kong pulled his bongos out. "Oh me oh my… these things are worn out! I should definitely repair these."

Kazooie turned to Blake. "Uh… what were you thinking of when she said instrument?"

"I… uh…"

"Dear Rareware, get your mind out of the gutter!"

Not my fault I like reading erotica! Blake thought.

"Oh, Diddy, I made this just for you. I meant to give this to you earlier but I was… distracted." She giggled and handed Diddy an electric guitar.

"Hoo hoo!" Diddy cheered and started jamming out.

"Banjo, do you want me to tune up your banjo?" Candy asked.

Sweet Oum, stop with the innuendos! Blake thought, blushing like crazy.

"Nah, I'm good. I just tuned it up a few hours ago."

"Blake, are you okay? You're burning up!" Ruby exclaimed.

"O-Oh, am I?"

"Okay. Kazooie, how's your kazoo? I could upgrade it for you if you want."

"I'm good!"

"Alright then." Candy turned to look at Ruby and Blake. "Hmm… would you like some instruments of your own?"

"Yeah, sure!" Ruby smiled.

"Uh… yeah, sure."

Candy giggled. "I know just the thing for you two." She said and went toward the back, coming back out with two instruments. "Here's a lovely Electric Keyboard for Ruby, and a harmonica for Blake."

"Oooooh, coooooool!" Ruby gushed.

"Thank you."

"Now, these two have a special effect to them when you play these. Just think of it as a… bonus." She giggled.

Blake blushed like crazy. "Wh-what kind of bonus?"

"Hmmhmmhmm, you'll see~!"

"I… uh… it's been nice talking to you!" Blake said and ran off.

"Huh? What's her problem?" Kazooie asked.

"Goodness gracious, was it something I said?" Candy wondered before shrugging it off. "Oh well, take care everyone… oh, and see you around, honeybunches." She said to DK and blew him a kiss, making Donkey Kong's heart go aflutter.

"Alright, come on, lover boy." Banjo said, dragging the gorilla out while Ruby waved goodbye to her and then walked out.

Resume Angry Aztec BGM

Blake was hiding underneath a palm tree. "I have GOT to stop reading erotica." Blake shuddered.

"You okay, Blake?" Ruby asked after they got out.

"Y-yeah, I'm fine. Probably just the desert heat." Blake lied.

"Again? You gotta wear lighter clothes!"

"I know!" Blake sighed. "Alright, let's just find our friends, get those blueprints and get those Golden Bananas."

"Right!" Ruby nodded as they walked off together.

"HEEEEEY!" A voice caught their attention as they turned their heads to see a cage with a trapped llama, but that wasn't the only thing they saw in the cage. They quickly ran toward the cage.

"Hey Sky! Didn't think you'd be trapped in here… with a llama." Ruby said.

"Ugh, tell me about it!" Sky sighed. "Do you think you can us out of here?"

"We can try!" Ruby nodded.

"Bolt cutters." Banjo requested where Kazooie pulled out some bolt cutters from the backpack.

"Bolt cutters!" Kazooie said as Banjo quickly cut the bars and then Donkey Kong pried them off, freeing them as the llama quickly ran off to a temple while Sky walked out.

"Freedom!" Sky exclaimed. "Soooo, who's the bear and bird?"

"Banjo and Kazooie." Ruby replied.

"I see. The name's Sky!"

"Nice to meet ya!" Banjo said, both shaking hands, and then Wrench, Sky's pet falcon popped out of Sky's pocket. "Oh! You have a bird too?"

"Yup! His name's Wrench!" Sky smiled as Wrench hopped up on Sky's shoulder and nodded at the duo.

"Well, howdy there!" Banjo waved at Wrench.

"Alright, I think we should follow that llama." Blake suggested. "I have a feeling we'll find more of our friends in there."

"Good idea!" Ruby nodded and then they ran off together until they reached the Llama's Temple, walking inside where they saw the same llama resting above a pool of lava while some Kritters were going about their day.

"That seems like an odd placement for lava." Blake mused.

"Oh! I have an idea!" Ruby grinned and pulled out her electrical keyboard.

"What will that do?"

"Oh, I'm thinking that this will be enough to wake this llama up and have him run over the Kritters. It'll be funny!"

"I second that!" Kazooie exclaimed.

"This should be good." Sky chuckled.

"Alright, give it a whirl." Blake said. "…You do know how to play the piano, right?"

"Shouldn't be too difficult!" Ruby said and then put her fingers on the keyboard. "Let's see… what do I want to play…" She wondered to herself, closing her eyes. "Aha! I got it!" She slammed her fingers on the keyboard, playing an electrical version of Red Like Roses Part II.

"A-ack! Wh-why can't I move?!" A Kritter exclaimed.

"I'm… I'm paralyzed! Why am I paralyzed?!"

Meanwhile, the llama stood up, awakened by the song, looked around and despite what Ruby had thought it'd do, it spat in the pool of lava which somehow cooled it off to where it was now water before lying back down for a nap.

"What?!" Ruby yelled.

"Well, that was unexpected." Sky said.

"Well, the good news is that the lava is gone and the Kritters are paralyzed." Blake pointed out. "The bad news? The pool is now covered in saliva. Ew."

"I'm not going in there!" Sky said.

"Well, there's no chance I'm going in that disgusting pool!" Ruby said. "I'd rather fight these Kritters instead of swimming in there! Banjo, how about you?"

"Um, I'd rather not swim in saliva." Banjo shook his head.

"Blegh! No thank you!" Kazooie protested.

"Ugh, great…" Ruby sighed. "Well, I don't know what's underneath that pool, but I'm not-"

SPLASH!

They immediately saw Donkey Kong and Diddy swimming through the water. "They're brave…" Sky mused.

"I'm sure they don't care." Ruby shrugged and then saw the still-paralyzed Kritters. "I'll be right back!" She said and quickly zipped off, quickly taking out the Kritters and Klaptraps with all of them screaming.

"Huh, does she seem a little faster to you?" Blake wondered, watching Ruby zip through the room while not even using her semblance.

"I dunno." Sky shrugged. "She still looks the same as ever."

Ruby returned to them. "Phew! That was a rush!"

"Ruby, were you… faster than usual?" Blake asked.

"Uh, what do you mean?"

"Oh, never mind." Blake sighed and then they heard a splash as they turned to see the Kongs returning, with a third Kong in tow.

"Hey there, funny face! How are ya!" Kazooie greeted.

"Banjo? Kazooie? Oh, it's been a while!" He suddenly stretched his arms, wrapping them around Banjo and pulled him toward him, hugging him tightly.

"Well, he's got a funny face." Ruby whispered.

"He doesn't look graceful." Blake said.

"Doesn't look like he has style, either." Sky muttered a bit.

The Kong in question saw the girls and happily waved. "Hello! The name's Lanky!"

"Nice to meet you too!" Ruby smiled. "I'm Ruby, this is Blake and Sky!"

"Hello."

"Sup?"

"Nice to meet ya!" Lanky grinned. "…Oh! That reminds me! Before I was locked up in this temple, I saw Tiny get sent to another temple!"

"Really?" Ruby asked.

"Yeah! I'll show ya!" He said and took off, the others following him as they raced across the desert to the other temple and then they ran in, where they noticed a large chunk of ice in the room. "Hmm, I don't know where she is."

"I have a feeling she's underneath the ice." Sky said.

"Well, how are we gonna get her out? We don't have a Fire Flower on us!" Ruby pointed out.

"Don't worry, I got this!" Banjo pulled a Shock Spring out of his backpack and then threw it next to the pool. "Let's go, Kazooie!"

"Right!" Kazooie nodded as Banjo stood on it and then sprung up in the air as Kazooie flapped her wings to fly around the room, before positioning herself. "Here we go!" She yelled and then unleashed Beak Buster, slamming into the ice and shattering the ice on impact.

"Ooooh! That looked like it hurt!" Blake winced.

"Nice going, bird brain!" A Kritter taunted. "Hope you like the afterlife!"

Banjo got out of the pool and then Kazooie shook it off. "You were saying?" Kazooie grinned.

"Uh… WHAT." The Kritter jawdropped before getting pelted by eggs. "Ack!"

"Are you okay?" Sky asked.

"Oh yeah, I'm totally fine!" Kazooie grinned.

"Guh-huh! Let's go!" Banjo said and hopped into the pool, where the others did the same and came into a large room, which held Tiny Kong.

End BGM

"Oh thank goodness!" Tiny smiled. "I can't believe they got me too…"

"Don't worry, we'll get you out of there!" Ruby exclaimed.

Sky noticed something in the corner of her eye. "Guys! Above us!" She yelled, catching their attention to see a large Necky coming in with a pirate hat on top of it. Diddy immediately recognized this and let out some angry chimpanzee noises.

"Krow?" Lanky translated.

"Doesn't look like a crow." Ruby said.

"I think that's his name." Blake sweatdropped.

BGM: Snakey Chantey (Super Smash Bros Ultimate)

"Go Wrench!" Sky yelled as Wrench flew over to Krow and tackled Krow, then dodged his swipes and then clawed him in the chest before flying back to avoid getting countered by the talons. Ruby quickly used her Boomerang to smack Krow in the face, catching his attention and flew over toward her. Diddy quickly brought out his Peanut Popguns and quickly fired at Krow, which he swiftly avoided and had his sights set on Ruby.

Blake brought out her Shadow Whip and flicked her wrist, the whip grabbing a hold of Krow and then she turned around and slammed him into the ground behind her. "Okay, I can get used to this." Blake smirked before summoning the Belladonna Claws and ran toward the downed Necky while Lanky slapped his silly with his arms and Donkey Kong punching him in the chest and Blake slashed through him.

Krow got back up and flew up to his nest, then he threw some large eggs at them, having them bounce around once they landed on the ground. Banjo picked one up and threw it back at Krow while he dove for Sky, the egg hitting him and having him fall to the ground, then Sky ran over to him and brought out a scimitar and then slashed Krow a few times before having Wrench dive bomb Krow and clawed him with his talons before flying off as Krow got back up and glared at the War Bird Trainer and attempted to claw her, but Diddy Kong flew in with his jet pack and kicked him right in the beak. Krow glared at Diddy and chased him, but then Diddy flew up in the air where Ruby threw her Crescent Boomerang at the Necky to strike him down.

Diddy let out some angry grunts and aimed his jetpack at him, then launched himself toward him and then slammed into him, the jetpack exploding and Diddy jumped out of the explosion while Krow slammed into a wall and fell to the ground, struggling to get up but fell limp after a few seconds. He then disappeared and left behind five blueprints.

End BGM

"Alright! Way to go, Diddy!" Ruby praised as Diddy Kong blushed a bit and scratched his cheek while Donkey Kong gave him a friendly noogie. They then lifted up the cage that held Tiny, where she walked out.

"Woohoo! That's what I'm talking about!" Tiny cheered.

"Come on, let's take these over to Snide." Ruby said after picking up the blueprints.

"Do we have to go all the way back to Jungle Japes, though?" Blake asked.

"Actually, I think I saw Snide's HQ here somewhere." Ruby told her.

"How did-… you know what, I'm not even gonna question it." Blake shook her head, where they all walked off back to Snide's HQ.

Meanwhile…

"Goodness gracious! You're asking me to join the Assist Trophies?" Chef Kawasaki asked, happily pouring some soup in his pot.

"Yeah!" Nora grinned.

"You can also help in the kitchen, I'm sure they wouldn't mind." Ren said.

"It's a deal!" Kawasaki grinned. "Do you have any other chefs in the kitchen?"

"We have a few, but they're kinda creepy." Jaune said.

"Aww, they can't be that bad."

A few minutes later, in the Smash Mansion kitchen…

"They're wire frames?!" Kawasaki exclaimed.

"Yup, when we're not training against them and getting our butts handed to them, the Fighting Wire Frames usually hang out in the kitchen and prepare meals." Jaune said.

"Nah, we usually kick their butts. Jaune's the one who's unlucky." Nora said.

"Hey!"

"It's usually different who cooks the meals." Pyrrha explained. "One day it's the Wire Frames, the next day, we may have either the Polygon team or the Alloy team." She said.

"Don't forget the Miis! They help out too!" Nora pointed out.

"I just can't help but think some of them look indentical to some of the Smashers…" Ren muttered a bit.

"Oh good, you see it too!" Jaune sighed in relief.

Kawasaki grinned. "I wouldn't mind some helpers! I'm in!"

"Excellent!" Nora grinned.

"Alright, Wire Frames! Allow me to show you what I can do!"

"Come on, let's go find another Assist Trophy." Jaune said and they took off.

Somewhere else…

BGM: Dr. Toadley (Mario and Luigi: Bowser's Inside Story)

"Do I hear someone approaching me? I most certainly do." Dr. Toadley turned around and saw Nyx approaching him. "Hello there, Nyx. Is there something I can help you with? I most certainly can!"

Nyx chuckled. "Hey, doc… there's something I need to ask you. It involves my teammate."

"Which teammate is it?"

"Xena."

"Ah, the little ticking time bomb. Yes… I remember her well… she troubling you?"

"Well, no… it's just, well…"

"Spit it out!"

"Oh, alright, it's what Mewtwo said to her!"

"Mewtwo is always blunt, but he does have a good, well-meaning heart. I'm sure he had good intentions. What did the creature say to her?" Toadley asked as Nyx explained the situation to him, as his expression suddenly turned dark. "…I see…"

End BGM

"Stare into my crystal ball." He requested as Nyx nodded and stared at it while Toadley began doing his magic. "What Mewtwo said, though extreme as he may be at times, is correct. Time is running out for the girl."

"What?!" Nyx whispered in horror.

BGM: Where is the Hope (Dragon Quest XI S: Echoes of an Elusive Age Definitive Edition)

"Yes… indeed. Mewtwo is doing everything he can to save her, before she gets swallowed by her mental instability. She may have had an episode when Bowser took over the castle and another when she fought Mega Man in her test. These episodes are getting more and more frequent. The last one had caught Mewtwo's attention during this last one and I believe she had an episode just the other day when Bowser and Torchwick attacked Toad Town. You barely got her to snap out of it when she heard those explosions caused by Bullet Bills. Mewtwo is stalling for time until he gets her to be one with her dark side. It is only a matter of time before she gets triggered again… and not just from an explosion."

"What do you mean?"

The crystal ball showed Mewtwo using Psyshock on Xena. "While extreme as it may be, he is attempting to save her life. For you see-" The crystal ball showed a different kind of Xena, one where she is standing up to Mewtwo's torment. "-Her dark side is slowly resisting the treatment. Xena is at a constant war with herself, desperate to become one with herself, but her dark side is fighting it. Mewtwo is a major threat to the dark side and he is doing everything he can to prevent it from escaping. The problem with this-" The crystal ball showed Dark Xena pushing Xena down. "-Is that the dark side doesn't want to be one with her. It is like it has a mind of its own." The crystal ball then showed her running toward Mewtwo with her sword out.

"No way…" Nyx whispered and quickly turned her head before she could see what she did with Mewtwo.

"Indeed. These episodes have been making her stronger. What may have started as PTSD and split personality issues has turned into something dangerous, and Mewtwo is trying everything he can to stop this from happening. Her dark side is desperately trying to block her out and have free reign on her body. If that happens, the worst case scenario will be what as Mewtwo had told you. I do not foresee any best case scenarios."

"No… there has to be a way to stop this!" Nyx said.

"If you find a way to stop your teammate from going off the deep end permanently, then find it now. Time is running out. The only logical way is for Mewtwo to do what he is doing right now."

"No… we'll find a way." Nyx told him. "Xena is our teammate, and I'll be damned if we have to resort to killing her." She said and then walked out.

End BGM

"Good luck, you are going to need it." Toadley gravely said and then his crystal ball showed him an image. "Oh? …Ooooh… what kind of scenario is this?"

Ya know, personally, I would've saved that Mario Maker 2 update for a Direct, but hey, you do you Nintendo.
