Meanwhile, in the Paper Universe…
BGM: Supreme Sparkling King, Bowser Battle (Paper Mario: Sticker Star)
"BWAHAHAHAHAHA!" Bowser roared. "No matter what you do, YOU CANNOT GET THIS ROYAL STICKER FROM ME!" He boasted to Team RWBY, the Mario Bros, Daisy, Villager, Isabelle and Banjo & Kazooie.
"Oh yeah! Well you can kill us if you pry all my feathers from my body, you big oaf!" Kazooie yelled.
"Rrgh, we have to try something… but what?" Blake rolled her shoulders as Bowser back handed Mario Daisy, and Yang away, then blocked a massive iceberg that was thrown at him.
"Oh come on, that should've counted for something!" Weiss, in her Fierce Deity outfit complained.
Rrrgh… none of our tactics are working. Reflet said. Come on, Reflet… think! We've got tons of stickers left and… wait… what the hell are we doing?!
"No matter what we do, we can't take him out." Kersti said. "…Wait, I got it! Mario, you have the scrapbook! Put me in there as a sticker and I'll power you guys up."
Mario pulled it out. "You sure?"
"Yes, trust me!" Kersti nodded as Mario opened it up. "Alright, here goes nothi-"
Suddenly, Reflet grabbed a hold of the book and yanked it out of Mario's hands. "Thank you~!"
"Huh?!" Kersti exclaimed in shock. "What are you- oh, I get it, you want to do it, miss leader of Team RWBY. Alright, put me in the scrapbook and I'll power-" Reflet burned it up. "-WHAT ARE YOU DOING?!" She yelled as it was nothing but dust.
End BGM
"Doing something I should've done a long time ago." Reflet responded. "We're better than this! Stickers don't define our power. We define who we are. Not some measly sticker."
"I get what you're saying but we're USELESS without them! We can't defeat Bowser now!"
"Oh, yes we can. We don't need some flimsy good for nothing worthless junk to power us up."
"Hello! Are you listening to what I'm saying here! We can't defeat Bowser now!"
"Bold of you to assume that we can't, you useless paperweight."
"WHAT DID YOU CALL ME?!"
"Fight! Fight! Fight! Fight!" Kazooie chanted.
"Kazooie!" Banjo scolded.
"This whole adventure, you're always just "nag, nag, nag". You never give any helpful advice, you're incredibly bitchy… I should've had Yang tear you up several areas ago… should I go on?"
"How DARE you! I come from the Sticker Star and your people hold an annual celebration for it in Decalburg!"
"Heh, Decalburg. Is that what we're calling Toad Town now? And from my point of view, this Sticker Fest whatever it is came out of nowhere. I haven't heard about it until the start of this adventure. Have any of you heard of it before?"
"Nope." Mario shook his head.
"Nada!" Daisy agreed.
"By all accounts… it doesn't make sense!" Luigi said.
"Even I thought it was weird we were supposed to "celebrate it"." Peach said, hanging on chains via Bowser tape.
"Big guy! Have you heard about this too?" Reflet asked.
"BWAHAHA-… wait, actually, no, I didn't. Never heard about it. Saw something glowing when I wanted to crash the party and took it."
"ARE YOU KIDDING ME!" Kersti yelled.
"There you have it."
"Well, I don't think you're seeing the big picture here. Stickers are a way of life and will help us win the day against Bowser. Now we can't… but no worries, I'm a sticker fairy and last I checked, people LISTEN to fairies!"
"Yeah, and I'm a host to Grima but you don't see me boasting about it!"
"…Wait, what? What's a Grima?"
"Here, why don't you be useful for a change." Reflet pulled out one of her tomes. "You can be a bookmark for a while." She opened it up.
"DO I LOOK LIKE A BOOKMARK TO YOU?!" Kersti yelled as Reflet slammed her tome shut on her. "Mmph! MMMMPH!"
"Yes." Reflet smirked. "Alright, let's do things our way now."
BGM: Duty ~ Ablaze (FIre Emblem: Awakening)
"Blake, Weiss, flank Bowser on the left. Yang, Daisy, Mario, take the right. Villager, Banjo, get Luigi and Isabelle up in the air. Once you've weakened him, I'll finish him off in style."
"You gonna sic Chrom on him?" Yang asked.
"No!" Reflet laughed. "That's my brother's job. I got something else in mind."
"Welp, you heard the lady. Let's do this!" Banjo said as he grabbed Luigi as Kazooie started to pull them up while Villager grabbed Isabelle and flew up with his balloons while everyone was in their respective areas.
"Monochrome, throw your magic at him!"
"I don't think so!" Bowser said as he swung his arm down, but Weiss would throw up an iceberg to block his attack as Blake would jump up on the iceberg and jumped over to Bowser as Weiss threw up a Kacrackle, then Blake's claws glowed as she Kazammle Slashed through the Kacrackle iceberg where small snowflakes were formed as they fell onto Bowser, then the snowflakes exploded into a mist. "Bwargh! Can't see!"
"Fireworks, let's knock him down a peg!"
Yang smirked, raising her fist up high and punched the air to launch two Firagas as Mario jumped up and hammered the Firagas to Bowser while Daisy equipped a Crystal Flower and punched the ground to create a stalagmite and then all three punched/hammered it, sending crystals into Bowser's face and arms.
"Gwargh!"
"Spiral Crossing, drop the hammer!"
Villager and Banjo dropped Luigi and Isabelle where Luigi's hammer burst into electricity while Isabelle brought her mallet out as the two slammed their weapons on Bowser's head, then Banjo and Kazooie dive bombed and crashed into him while Villager dropped a bowling ball and then landed on the ground.
End BGM
"Excellent. Now… time to tip the scales in our favor." Reflet said. "All of you clear a path. I'll finish this off myself." She brought out a Smash Ball and crushed it, but instead, her eyes suddenly glowed red and a dark aura surrounded her. She flashed a toothy smirk. "I'LL WIPE YOU OUT!" She yelled, snapping her fingers as Bowser was suddenly put into a void.
"What…?! Where am I?!"
"Hmhmhmhm~" Reflet levitated toward him. "Filthy vermin, I'll wipe you from the face of this planet!"
BGM: Main Theme (Fire Emblem Awakening) (Start at 1:01)
Grima himself appeared behind Reflet. "PERISH!" She yelled as Grima unleashed a powerful dragon breath attack as Bowser breathed fire to counter it. "Oho, naughty fella, aren't you!" Reflet smirked sadistically as Grima snarled and headbutted Bowser, slashing him away.
"ARGH!"
"Now, as I was saying… PERISH!" Reflet cackled as Grima unleashed his massive purple dragon breath attack as Bowser let out a pained roar… before the Royal Sticker popped off of Bowser's head as he fell to the ground in defeat.
End BGM
"Now lay down there like the vermin you are!"
"…Mind if I have him as a snack?"
"No."
"Hmph!"
The void disappeared as Reflet turned back to normal. "Phew. Now that was a satisfactory finish for Team RWBY and co, if I do say so myself." She said.
"…Remind me to never get on her bad side." Mario whispered.
"Noted." Daisy agreed.
"Hmm! Mmm! Rrrrgh!" Kersti managed to wiggle her way out of the tome. "Phew… oh look, we have the last Royal Sticker. Or should I say the only Royal Sticker because SOMEBODY INCINERATED THE REST!"
"What are you talking about?" Reflet pulled up the other Royal Stickers. "I pulled them out before I burned that scrapbook up."
"…But… how… I… I didn't even see- oh forget it! Let's just go." Kersti mumbled as the Mario Bros freed up Peach.
"Thank you!" Peach smiled as they walked off, leaving Bowser to himself where Junior, Kamek, General Guy, Neo, Roman and Marnie walked in.
"Told him it was a bad idea from the start." Marnie shook her head.
"Indeed." Kamek nodded, using his magic to wake him up.
"Mmm… ooogh…" Bowser rubbed his head. "What happened? Last thing I remember I was at some festival and now… now I'm here?"
"Oh papa, what are we gonna do with you?" Junior chuckled.
Later, at Decal- I mean Toad Town…
"Ah, there we go. The Sticker Comet is back in one piece!" Kersti said. "Now we can enjoy the rest of this festival and-"
Suddenly, a Launch Star appeared over the comet, where it would pull them up and sent the Sticker Comet and Kersti back into space. "AIYEEEEEEEEEEEEEEEEEEEEE!"
"Honestly, it's about time we did away with this nonsense." Rosalina said, where Reflet high fived her.
"Agreed."
"Now how about we have a better festival?" Rosalina raised her wand up as Star Bits started raining down from the sky.
"Now this is more like it." Peach giggled.
Yang looked up at the sky, watching Star Bits raining from the sky. She closed her eyes, thinking of how Ruby would have enjoyed the raining Star Bits.
BGM: Luma (Super Mario Galaxy)
"Ruby…" A tear ran down her cheek. "Why.. Why did you run away?"
"Yang… we'll find her." Weiss said. "I don't care how long it'll take, months… years… we'll find her."
"I hope it doesn't take that long…" She mumbled as Weiss and Blake hugged her tightly, then Reflet turned her head to see JNPR arriving.
"Ah, team JNPR." Reflet smiled. "Please tell me you have good news." She said, but all of them looked away as Reflet frowned. "…Oh. No luck?"
"We tried every inch of Hyrule and got the Champions of Hyrule looking for her as well… but they're coming up empty." Pyrrha said.
"It's a mystery… where could she have gone?" Ren wondered.
"Not only that, but JINXY had contacted us. They were in Atlas and Esdeath told them she's searched the entire continent for her but she hasn't seen 'em. Ironwood put up a search warrant for Ruby." Jaune said.
"Mmmph…" Reflet closed her eyes. "Dammit… where did she go? She couldn't have gone that far, right? Finding Ruby is our top priority, we have to find her no matter what!" She said as she turned around to give Yang a hug as well. "We'll find her… I know we will."
End BGM
Meanwhile…
"Come on, Ruby… where are you…" Penny said, flying through the sky with SAPR.
"…Oh! I picked up on something!" SAPR exclaimed.
"You did?!" Penny said as her radar picked up on something as well. "So did I. Let's move!"
With Chaos Ruby…
"Dimentio… is he still alive? …Why did I see those images…" Chaos Ruby wondered to herself, closing her eyes and remembering what she saw. Dimentio throwing Ruby down into the Phazon… she could feel the Phazon burning on her. "Agh!" She yelped as she panted, wiping away her tears. "Please… tell me she's okay…"
"Found her! She's in this cave!"
Chaos Ruby flinched. Please be a different cave, please be a different cave, please be a different cave… She thought as Penny walked in. Her eyes widened and disappeared into the shadows.
Penny scanned the cave. "Ruby, I know you're in here." She said as she walked in with SAPR walking in as well.
Who the hell is that? Ruby thought, staring at SAPR while hoping Penny wouldn't see her. Go away, go away… go away…
"Aha! Found you!" Penny grinned, taking Ruby's arm. "Mission accomplished, we got her!" She said as she started dragging her out.
"Ah! LET ME GO! LET ME GO!" Chaos Ruby protested as she was brought outside as Penny turned to see her, letting out a gasp.
"Oh my goodness, how long were you in here?!" Penny said as she had paler skin, her hair was even longer and had even more of a slouch, there were still some baggage under her eyes.
"Oooh, might I suggest she go into a tanning salon?" SAPR suggested.
"Go away!" She yelled. "And who the hell are you?!"
"Ruby, easy… easy! This is my sister, SAPR. She used to be known as R3-B7 but she was taken care of. Dr. Eggman didn't take into account that RWBY is now being led by Robin's twin sister."
"On the bright side, at least I know what Nosferatu does…" SAPR rubbed her head.
Chaos Ruby let out a scowl. "…I see, so they're getting along just fine without me. I should've known Ozpin would have permanently replaced me."
"Ruby, listen to yourself. This isn't you!" Penny told her. "This Dimentio guy put all this stuff in your head and changed you drastically. Please… come back to us. You'll be fully healed, we can take you to Byleth."
"Yeah, well, she didn't do that great of a job, did she?" Chaos Ruby glared. "It's fine, whatever… I'm fine living on my own, out here in the wilderness roughing it… feels great!"
"But your damaging yourself. Ruby, as your friend… you need to come back and properly heal. Dimentio said it was irreparable, but maybe he had missed something. Please-"
"Dimentio…" Chaos Ruby snarled. "Dimentio… DIMENTIO DIMENTIO DIMENTIO DIMENTIO DIMENTIO!" She screamed as she aimed her hand at Penny and lifted her up. "DON'T YOU DARE MENTION THAT BASTARD IN FRONT OF ME! EVEN IN DEATH, HE'S STILL HAUNTING ME AND YOU DARE MENTION THAT PRICK?!"
"Nnngh! Ruby…!"
"Drop my sister, Ruby!" SAPR ordered, aiming her arm at Ruby only she would telekinetically throw Penny to her as she threw a few Chaos explosions at them.
BGM: Sad Girl (Super Mario Galaxy)
"Hah… hah…" Chaos Ruby panted as she stared at Penny and SAPR, her eyes widening after she calmed down. "…No… what have I done…" She clutched her head and fell on her knees, tears falling nonstop. "This is why I ran away… I hurt people when I'm hurting… I hurt dad… I hurt Zwei… I hurt Byleth… I couldn't bear it anymore…"
Penny stood up. "Ruby… your father, Zwei and Byleth are okay. They're doing a lot better. Please-"
"No… don't you see? I've hurt so many people with this cursed power… i'm severely unstable... if you stay here, I'll hurt you again…" She got up and turned around. "I'm sorry, but I need to leave… don't follow me. I'll only hurt you more… "
"Ruby! Don't go! Please, come back to us! We can fix you!"
"GO AWAY!" She screamed, waving her hand as both Penny and SAPR's HUDs started to malfunction.
"Nnngh! What are you-"
"Disabling your radar… so you can't follow me." Chaos Ruby turned around. "Goodbye… Penny…" She took off running, using her slow down time powers to disappear from the two.
"RUBY, WAIT!" Penny yelled as she was long gone. "Ruby…" She teared up as she fell on her knees.
"Sis…? Are you okay?" SAPR asked as Penny sniffed before punching the ground in sadness.
"We couldn't save her…" She quietly said, tears falling from her eyes. "SAPR… go back to Toad Town and report that we found her."
"What are you going to do?"
"…I'm going to go after her. I'm going to save her." Penny said, activating her thrusters and flew off, desperate to find Ruby again.
I said I wasn't going to do Sticker Star. I never said anything about doing the last bit of Sticker Star in a Gaiden.
Ibuki: Hooray for loopholes! ...Ruby-chan...
Yeah... that's rough...
