"Alright, so how many Power Stars do we have in total?" Eggman asked.
"We have a grand total of 125 Power Stars." Rosalina said as she had a white board up as Palutena was also there with them. "Now we could have already gone to the center of the universe with 60, but everyone wanted to collect every last Power Star that they could."
"Then we have plenty." Eggman said.
"Hmm… alright, so say if we have a shot on stopping the universe from imploding." Palutena said. "We stop Bowser… and then what? We just wait for the galaxy to collapse in on itself?"
"Like I said, there's one solution I have in mind. I do not like it, but it's the only thing I can think of." Rosalina said.
"I think I know what you mean…" Palutena said solemnly.
"Rrrgh, if I could think of another alternative, I would." Rosalina folded her arms.
"While you are preparing for your solution, I am going to create a force field that should be big enough for the Observatory, the Typhoon and Peach's Castle. It will not save us from the black hole, but it should be enough to delay the inevitable from us getting spaghettified." Eggman explained. "That should give you enough time for your solution to work."
"They will do it without a moment's hesitation." Rosalina said to him.
Eggman smirked. "I am not sure what you mean by "they", but let us hope they will succeed."
At the Blue Typhoon…
"So, this is it then." Byleth said as she, Dorothea, Ilia, Mercedes, Gloria, Washington and Qrow were all gathered in one spot. "We have one shot at this, and if we don't succeed… we're all dead."
"Eh, I don't have any plans for tomorrow." Gloria said, sitting down and stroking Zacian's fur. "Fock it, if it means all of us dyin' to a blackhole, we might as well go out in style."
"Couldn't have said it better myself." Qrow chuckled.
"Let's just hope it goes well." Dorothea said.
"Definitely." Washington agreed, watching Mercedes hold on to Ilia.
Gloria, meanwhile, pulled out her phone and looked at her contacts. She looked at Hop, Marnie and Bede in her group texts and let out a sigh. To think I never said goodbye to these dorks. She thought as she started texting them.
Hey, I just want you to know… that I love you guys.
Aww! I feel loved! We love you too, ya big doofus! - Hop
Appreciate it. Love you too. - Marnie
…Okay, what is this about? - Bede
Don't worry about it. I just wanted to tell you guys that I love you. - Gloria
Something's up… you okay? - Bede
I'm fine. I promise. Gloria texted back, then added a heart emoji before pressing send and then put her phone away. She let out a sigh and leaned her head on Zacian's shoulder. "You think we're gonna be okay?" Gloria wondered as Zacian let out a small whine and licked Gloria. "Yeah… I hope you're right." Her phone then buzzed as she saw that her mother was calling her. "Mum?" She wondered as she answered it. "Hello?"
"Gloria, honey, are you okay? Marnie just called me asking if you were alright."
BGM: Here With You (Mirai Nikki)
"Yeah, I'm fine…"
"You don't sound okay. Something the matter?"
"Yeah… I'm just… going through something at the moment." Gloria said. "It's nothing serious."
"Aww, my poor baby… well, you powered through the Darkest Day and stared at a massive creature in the face that would have killed you, but you caught it. Whatever it is that has gotten to you, make sure you scream at the top of your lungs and tell whatever it is that you are gonna, and I quote: "Make it's day fockin' shitty."." She said, causing Gloria to snicker and then let out a giggle. "You always were one hell of a fighter no matter what was thrown at you. You always laughed it off like no big deal."
"That's true… I did." Gloria said, trying her hardest not to tear up.
"You may be champion of Galar, but you're still my daughter… and if you feel the need to come home for a while, I'll be here. You know that, right?"
"Of course…" Gloria smiled, a tear running down her cheek.
"Glad to know everything's alright. Love you!"
"Love you too… oh… and… mum?"
"Yes?"
"I… see you later." Gloria said, her voice slightly trembling.
"I'll be here!" She said and then hung up as Gloria fell on her knees, punching the ground with her fist.
"Dammit!" She quietly said.
"Hey… you alright?" A voice asked as she looked up to see Byleth kneeling down.
"I… I don't get it, Byleth… I've stared death in the face numerous times with you lads and lasses, but this… why the hell is this one getting to me?!" She wondered as Byleth said nothing but wrapped her arms around Gloria in a loving hug, gently putting her head on her chest.
End BGM
Pyrrha and Jaune sat by the garage, staring out into the cosmos. "I have to say… that was… quite the revelation." He said. "We're all going to be dead all because of their carelessness."
"Yeah…" Pyrrha agreed.
Jaune let out a sigh. "I'm gonna be honest… when I imagine myself going out, I imagined I'd be dying of old age by someone who I love and admire." He said. "Guess that won't work out now…"
Pyrrha put a hand on his wrist. "Perhaps in some different universe, it would have worked out."
"Yeah…"
"Jaune… if we don't make it… I just want you to know… that you are the bravest teammate I've ever met."
"Aww, thanks…"
"And there's something else I've been meaning to do." Pyrrha pulled him in close and then kissed him. Jaune's eyes widened in surprise before closing his eyes and wrapped his arms around her in return, as both Nora and Ren watched this.
"Well, it's about time." Ren said as Nora took a picture of Jaune and Pyrrha.
"Now if only I had Jaune's family in my contacts…" Nora mumbled.
"Look alive, people! We got a princess to save, and perhaps the whole universe!" Captain Toad said as he walked over to his ship along with the Toad Brigade, moving past Nora and Ren.
With Penny…
"We'll keep her in here for the time being." Tails said, having put R3-B7's remains in a room.
"Right…" Penny nodded, still a bit sad as Ruby was next to her, as was Susie.
"Don't worry, if that Ibuki girl says we'll be okay for whatever reason, then there's no need to be sad!" Nitori grinned.
'I guess so…" Penny quietly said.
With Hiyoko…
"Hey, Hiyoko!" A voice said as Hiyoko turned to see Sarge approaching her. "I've been meaning to talk to you about something."
"I've been meaning to say something as well." Hiyoko said. "I have to say, I was wrong about you. When Ibuki showed me the footage when you guys were kicking ass, it made me realize… you guys can kick some serious ass together. You're more than just idiotic goofballs."
"Indeed!" Sarge said. "We may be Red vs Blue, but when we put our heads together, we do it in style! They may be dirty blues, but they're damn good dirty blues. …Don't tell them I said that." He said, causing Hiyoko to snicker. "Well, maybe you can tell Caboose, but I doubt he'd keep his trap shut." He said. "Anyway, I didn't even know you come from a background where despair was passed around like the common cold! Had I known, I wouldn't have been so hard on ya… actually, I probably would have stopped Tucker."
"No no, it's fine." Hiyoko said, waving it off. "Look, if anyone should be sorry, it's me for saying all that stuff about you guys."
"Heheheh." Sarge walked over and patted Hiyoko on the head. "You're a good kid, you kimono wearing goofball. It's all water under the bridge." He said as Hiyoko nodded. "Now then…" He cocked his shotgun. "What say you that we kick this supermassive black hole's butt?"
"Not really possible, but I do love that enthusiasm." Hiyoko giggled.
With Rosalina…
"Okay, this should be enough." Rosalina said as she heard footsteps behind her where she turned to see Summer approaching her. "Oh, hello Summer."
"Hey." Summer greeted. "So, listen, I've been meaning to tell you something."
"What is it?"
"I don't have long in this world, as you know, I only came to put a stop to Dark Ruby. But, I've been seeing you having an interest in Ruby and I don't think it's just about her silver eyes."
Rosalina blushed. "You… you know?"
"Yeah." Summer nodded. "And I think you'll be perfect for them. I mean, I'm gonna be honest, I haven't been around Ruby and Yang for so long that it just feels kinda… weird. They were so little when I left, and I come back and I see them as fully grown teenagers. It's just… weird, you know? I never watched them grow or seen them spend their childhoods as innocent little kids. But you… you've had plenty of kids throughout your life and you've watched them leave your home and turn into planets, comets, Launch Stars… just to name a few."
"Summer, what are you saying?"
"I'm saying that when I'm gone, I want you to watch over Ruby and Yang. I think you'll be a good mother to them."
Rosalina let out a small gasp. "What about Tai?"
"I think you'll be good to him too."
"Okay, time out." Rosalina said. "While yes, it's true that I'm a good mother… I don't know what it'd be like if I just inserted myself into their lives, especially as they're older kids."
"I've seen them much happier when I came back… and I've seen Tai much happier that I haven't seen in a long time. It just… pains me that I will have to leave them again."
"Summer…"
"So please…" Summer looked at Rosalina. "Have them be attached to you like they are with me. I know I told them I'll spend time with them, but… I don't know how long I have until Dark Ruby's gone for good…" She said, tears starting to form in her eyes.
Rosalina let out a soft smile and walked toward Summer, then hugged her. "You're a good mother, Summer… I'll make sure I'll watch over them when you're gone."
Summer sniffed a bit. "Thank you…" She said, returning the hug.
Palutena walked over to Weiss. "Hey Weiss." She said as she turned to look at her right as Mercedes was healing her sprained ankle as it was acting up.
"Hmm? What is it?"
"I figured since we're approaching our final battle…" She handed her the Seregios armor. The armor has a razor like appearance as the two armored legs were colored silver with a talon tip at the end. The chest armor has a feathered appearance with silver scales as a coat, a blue belt with white feathered shoulder pads. The sleeves on the arms have silver armor on her shoulder and her hands. There was also a white tiara that was shaped like a feather with the Schnee symbol.
"Oh!" Weiss smiled as she took it, where it would disappear… only for it to be summoned onto her body. "Oh my!"
"Yup, you look ready for battle." Palutena smiled. "You can feel free to summon it however you like."
"Thanks." Weiss said as she turned to her team approaching her.
"So, you ready for this?" Yang asked.
"It's like we don't have a choice." Weiss said. "We do this or we don't. Either way, we're screwed."
"Exactly." Blake nodded.
Ruby let out a sigh. "So this is how our team ends… by a massive black hole that takes out everything."
"Aw, cheer up! At least we had a lot of fun!" Yang grinned.
"Mmm, you do know that Ibuki said we'd be okay, right?" Weiss asked. "…Even then, I'm wondering how that's even possible."
"Let's just hope for the best." Ruby said as they turned to see Mario, Luigi and Daisy approach them.
"Hey, if we don't get out of this somehow… we just want to say… it's been a hell of an honor working with you." Daisy said.
Ruby smiled. "Oh… it's been fun with you guys."
"Even if Ibuki said we'll somehow make it out, it's been fun." Mario said.
"To the bitter end!" Luigi said as they all hugged each other… and then they heard the Blue Typhoon roaring to life as they saw Sonic on the runway.
"We're getting ready to go!" Sonic called out. "You guys ready?"
"We're ready!" Nora called out as Pit walked over to Ruby.
"It's gonna be dicey…" Pit said.
"It always has been." Ruby said as the two embraced. "If we don't make it out of this… I love you."
"I love you too." Pit responded, with both of them sharing a kiss.
"Mmmph… now I wish Claude were here." Yang sighed. "Eh, if we somehow make it out of this, I'll give him one."
"Alright, prepare yourselves everyone. We're going to finish this once and for all!" Palutena said as she turned to Rosalina who was standing at the top of the Observatory. "Alright, you're good to go!" She called out.
With a nod, Rosalina raised her wand up in the air and fired a shot up into the air, creating a forcefield around the Observatory where it started to transform into a comet before blasting off toward the Center of the Universe with the Blue Typhoon right behind it.
BGM: Grand Star Rescue (Super Mario Galaxy)
At Peach's Castle…
"Sire!" General Guy came running up to him. "We got news!"
"What is it?" Bowser asked.
"We got a comet heading this way!"
"Eh? It's just a comet. No big deal."
"Yeah, but there's a massive ship right behind it!"
"Yeah, ships are behind comets all the ti-… WHAT?!" Bowser yelled as he took a look, seeing a comet approaching them with the Blue Typhoon behind them. "Dag blast it! It's those heroes! LAUNCH THE AIRSHIPS AT THEM!" He yelled. "Get the Koopa Troop! Get the Badniks! GET EGGMAN! …WHERE IS HE?!"
"We have reports that he bolted and never came back." A Hammer Bro said.
"Rrrgh… TRAITOR!" Bowser roared.
With the others…
"Alright, we're closing in!" Rosalina said, unbothered by the airships firing at them as the Observatory came to a stop but she held up the forcefield. "Alright, this is it! Let's go!" She said, making a light bridge for all of them leading to Peach's Castle as they all ran/flew in, where they would run into a portal.
End BGM
BGM: The Galaxy Reactor (Super Mario Galaxy)
They would come out of the portal as they would find themselves in the middle of a battlefield, and then they saw a full army of the Koopa Troop, Badniks and even a few Erdrean Monsters that were there consisting of some Etheral Serpents, Bloody Hands, a Jerkules, Hellriders and Skelegons. Even Kamek, General Guy, Metal Sonic, Roman and Neo were there as well… however, Cinder, Emerald and Mercury were not with the group. In fact, they were in the shadows attempting to stay out of it for they do not want to be seen by the others.
"Wait a minute, a few of the monsters from Erdrea are here?" Blake asked.
"Hey! What's the big idea? We didn't see you guys in the galaxies that we were i-… never mind! We gotta stop Bowser's plans! Just move out off the way!" Yang said. "We got a universe to save because your boss screwed up big time!"
"Why should we believe your liesssss?" An Etheral Serpent hissed. "You will not sssstop Lord Bowssssser, not even that traitorous Dr. Eggman!"
"As for your other question. The other monsters are busy building a community… and they're just about to do the finishing touches. They will celebrate its opening when Lord Bowser conquers the universe!" The Jerkules declared.
"Bwahahahaha!" Bowser walked over to them. "You honestly think you can easily stop me this time? And who told you that this galaxy is about to blow up? It's not gonna happen!"
"I did." A voice said as the Egg Mobile lowered itself.
"Robotnik!" Bowser snarled. "You told them these lies?"
"I only told them the truth. The seven Grand Stars we collected weren't enough. If we do not do something, the universe will collapse." Eggman said.
"Bah! I don't listen to traitors… and I don't listen to those who think my plans will fall!"
"Enough talk!" Mario said. "Where's Peach?"
"Hahahaha!" Junior came flying in with his airship. "You looking for Peach? Well, too bad… because she's with ME!"
"Peach!" Mario exclaimed.
"Mario! Guys!" Peach smiled.
"Heheheh." Junior flew behind Bowser. "Ready to fire, papa!"
"Good." Bowser smirked as several airships came in and a lot of Sumo Bros, Sledge Bros, a few Shy Guys holding Chain Chomps, Broozers and even several Bomb Boos came off of the airships to join the Koopa Troop.
"Whoa! That's… that's a bit overkill!" Pit said in shock.
"Koopa Troop… ATTACK!" He ordered as the Koopa Troop rushed at the group… when suddenly a pillar of light appeared before the two sides. "What?! What's going on?!"

"You put Power Stars into my children… That is UNFORGIVABLE!"
BGM: Determination (Hyrule Warriors: Age of Calamity)
Viridi walked out of the light, and was joined by Phosphora, Arlon, Cragalanche, and an army of the Forces of Nature walked out, but they were also joined by Dino Piranha and Fiery Dino Piranha. "WHAT THE?!" Bowser yelled.
"Alright, now it's an even fight!" Palutena said.
Xena smirked. "Oh, now this is more enjoyable."
"Phosphora! Arlon! Cragalanche! Children!" Viridi aimed her scythe at the Koopa Troop. "Let's raise some hell!"
"Yeah! Let's kick some ass like always!" Yang exclaimed as they charged at the Koopa Troop as Bowser could only watch in awe as Junior would provide air coverage by firing cannonballs at the group.
Bowser would turn to Roman and the others. "Don't just stand there! Get in there!" He ordered as they quickly jumped into the fray. "Rrrgh, where's Cinder and those cronies?" He wondered to himself as he noticed a meteor coming down on him. He let out a surprised yelp as he jumped out of the way as he spotted Rosalina approaching him.
"Remember me?" Rosalina said, aiming her wand at him.
"Bwahahaha! So we meet again." Bowser smirked. "Too bad your friends are getting slaughtered." He cockily chuckled.
"I would say the same to your army." Rosalina shot back.
"Heh! Well now… let's get down to business!" Bowser chuckled.
"YOU!" A voice yelled as they turned to see Ibuki approaching Bowser. She stopped walking and then dramatically pointed at him, her guitar pick between her index and middle fingers. "You've caused us a lot of trouble by taking these Power Stars! All for what? Your own ego? Peach-chan baking you a cake? Just showing that you're better than some pudgy plumber? And yet, here she is, having braved everything you can throw at her!"
"Oh, it's the lunatic again. Pffft! Like you're supposed to be a threat!"
Ibuki scowled. "Oh, you laugh now, but you've never known what Ibuki's done. She's braved all sorts of dangers searching for her princess! She's walked through the depths of Hell, fought the Doomslayer to a stalemate, and is living to tell the tale! But all this is gonna cause a giant ol' mess, and it's putting her classmates in a whole bundle of danger! Not gonna happen... Ibuki's gonna rock your world so bad, this'll be an encore performance you won't be forgetting anytime soon! Prepare yourself for a death metal assbeating!"
"BWAHAHAHA! Nice little speech. You wrote it yourself for your little "princess"?" Bowser taunted. "Here's what I think… the both of you will fall from the King of Awesome!"
"King of Awesome? I'd say the King of Recklessness if I've ever seen one!" A voice said as Hiyoko managed to sneak past the battle. She had equipped the Rock Mushroom. "I've got a foot with your name on it… and three guesses to where it's gonna go and the first two don't count!" She declared, getting in a battle stance as did Ibuki and Rosalina.
"Hiyoko-chan! Rosie-chan! Let's give this Koopa King a concert he'll never forget!"
"You got it!" Hiyoko smirked.
"Let's do this." Rosalina held her wand at the ready.
End BGM
Bowser let out a cocky chuckle, getting in a battle stance and roared. "SHOWTIME!"
BGM: King Bowser (Super Mario Galaxy)
Intergalactic King of Awesome - Bowser
Bowser breathed fire at the trio, but Rosalina would swiftly make the flames go around her as Hiyoko would stomp her foot on the ground to create a rock wall that would knock Bowser up into the air as Rosalina would fly up and would fire a point blank cosmic blast at him that would send him crashing to the ground where Ibuki would quickly swing her battle axe at Bowser before retuning her guitar as she strummed it as electricity shot out and hit him head on.
Bowser got back up and went into his shell, rolling toward the trio as they rolled out of the way while Rosalina held him in place with the telekinesis, but Bowser turned around and managed to power through her telekinesis as he tried to swipe at her, but Ibuki would slash at him to knock him away. Bowser would then swat away a few boulders thrown at him as he ran over to Rosalina and jumped into the air to try and Bowser Bomb her, but Rosalina stepped out of the way and aimed her wand at him, firing a laser directly at his face.
Rosalina then aimed her hand at him and charged up another cosmic energy shot as Bowser would attempt to grab her, but Hiyoko would cartwheel into a boulder and slam into him to push him back as Rosalina would then shoot a cosmic blast at him, hitting him head on as Ibuki jumped over and swung her axe down, hitting him upside the head as he grabbed her by the neck and slammed her to the ground. He then raised his foot to try and crush her, but Hiyoko would roll into him to stomp him as Rosalina used a heal spell on Ibuki just in case.
"Thanks!" Ibuki smiled as Bowser would do a Bowser Whirl to try and hit them, but they jumped back as Ibuki would rush over and swing her axe to hit him in the chest and then hit him with a few lightning bolts for good measure, then Rosalina would lift him up from the ground and fired a few energy blasts. Bowser was knocked back by these as another blast was fired at him, but he blocked with his arms, deflecting the cosmic blast as he rushed over at Rosalina as the latter did the same, as they swung their fist/wand into each other and knocked each other back as Bowser jumped over and swiped at her, but she conjured up a force field to block the attack. Bowser was undeterred as he would pull back his fist and delivered a powerful Bowser Punch that would shatter the shield on impact.
"What?!" Rosalina yelled in shock as Bowser grabbed a hold of her and slammed her into the ground. He then breathed fire right at her but she teleported behind him and would throw down a meteor at him as he turned around and shattered it with a single punch, but when the meteor shattered, Ibuki came through the debris and slashed at him, striking him with more thunderbolts and then Hiyoko would run over and rock punch him in the face to send him back a few feet. Rosalina would then teleport near him and then held him in place while also charging up a powerful cosmic blast as she fired it, sending Bowser flying away into the massive planet in the distance.
End BGM
"Did that get him?" Hiyoko wondered.
"No, I have a feeling he isn't finished yet." Rosalina said and turned around. "Anyone who is willing to go with us, now is the time!"
"We'll go!" Mario said as he, Luigi, Daisy and RWBY came running over.
"Good. Now let's finish this." Rosalina said and teleported them to inside of the planet.
"Ugh…" Bowser groaned as he stood up as Rosalina appeared with everyone else. "NO!" Bowser roared. "I have not come all this way to watch my galactic empire fall apart!" He declared. "This galaxy will last forever!"
"Bowser, you don't get it! This whole thing is gonna implode and we're all going to die!" Yang said.
"She's right! You're putting everyone at risk!" Ruby said.
"If you stop, we can find a way to stop the universe from collapsing in on itself!" Mario said.
"No! I refuse to listen to you teenagers and plumbers for a second longer! I'M ENDING THIS!"
BGM: Final Battle with Bowser (Super Mario Galaxy)
Bowser rushed over and delivered a hard punch at Mario, but he would block this and delivered a hard blow to his stomach in retaliation where Luigi would jump over and hammer him in the head. Bowser snarled and then Bowser Whirled the two away as he saw Daisy running over and delivered a few punches and kicks, but Bowser grabbed her leg and slammed her into the ground. Daisy got back up to shake it off as she delivered a roundhouse kick to knock him away.
Ruby used her semblance to rush at him and slashed at him when she got close, but he swatted her away. Ruby recovered and quickly shot him with her scythe to which he soaked the shots very easily as Weiss slashed at him with Eiskönigin, but Bowser grabbed her sword and smirked. "Nice armor you got!" He said, punching her in the chest to send her sliding as he then breathed fire at Yang and Blake, forcing them to dodge the attacks as Hiyoko snuck up behind him in rock form and rolled right into him to knock him forward as Ibuki would deliver a few swings with her battle axe as Rosalina would rush over and deliveed a cosmic kick that sent him sliding.
"What the hell are we doing?" Yang asked and whistled to call her Yellow Wisp, giving the others the idea to do the same as the Wisps went inside RWBY where Bowser breathed fire.
"VOID!"
Blake would absorb all the fire from Bowser and then shot it back at him to where he was able to dodge it.
"DRILL!"
Yang drilled into Bowser as he tried to stop her by grabbing her, but Ibuki would run over and together with Luigi, they would fire lightning bolts to stun him as he was then pushed back by Yang's drill attack where Rosalina would float up and throw a comet at him and struck him that send him flying back but he recovered and rolled straight for Rosalina.
"CUBE!"
Weiss stabbed the ground as ice blocks got in Bowser's way, stunning him for a few seconds as Hiyoko would roll into him and then delivered a few graceful rock punches and kicks before stomping her foot into the ground to cause a rock wall to slam into Bowser and hid him go flying into the air.
"LASER!"
Ruby locked on and fired, hitting Bowser in mid air as he fell to the ground and bounced a few feet where Daisy got into position and Crystal Punched him which caused him to roll on his shell as Luigi got into position and did a spin attack that that sent him spinning around and headed straight for Mario as he got into position and did a spin attack that knocked him into the air… and out of orbit.
End BGM
Bowser let out a loud defeated roar before falling into the lava planet below. "Is… is he going to be okay?" Hiyoko wondered.
"Ah, he's dunked into lava all the time. He'll be fine." Yang waved it off… when suddenly the planet they were on started to shake. "Gah! Now what?" She wondered.
"Pointing!" Ibuki pointed as they looked to see the last Grand Star burst out of the planet, and it was also accompanied by a Purple Chaos Emerald!
"The last Emerald!" Ruby grinned as the two objects gently flew down toward them as Rosalina walked over to collect the Grand Star while Ruby took the Chaos Emerald.
"That'll do it." Rosalina said, but then a massive bolt of lightning struck her. "GAAAAAAAH!" She yelled, feeling herself get paralyzed.
"Rosie!" Yang exclaimed as they were also struck by lightning. "Hnnngh!"
"Aaagh! What…?!" Ruby wondered as Kamek came flying in and grabbed the Grand Star.
"Your Nastiness! Catch!" Kamek said, throwing the Grand Star into the lava where Bowser's arm reached out and grabbed it where Bowser clenched his fist to absorb the power and then he shot out and landed back on the planet before growing gigantic. He then let out a loud roar that caused all of them to fly away and landed back at the battle arena where everyone else was at.
"Oh hey guys. Where's the Grand Star?" Travis wondered.
"Nnngh… take a lucky guess!" Yang said as Bowser landed in front of them, now a gigantic beast as he roared loudly.
"I WILL NOT LET YOU RUIN ALL MY HARD WORK!" He roared.
"…Sonic." Tails said. "Think maybe we oughta-"
"Oh yeah!" Sonic nodded as he took off and then came back with the other Chaos Emeralds. "Alright, everyone! Just like with Elder Princess Shroob!" He said as Ruby's eyes sparkled.
"Oh yeah!" Ruby smirked.
"So, what's gonna happen? Inquisitive minds wanna know!" Tucker asked.
"Basically we get a boost of power and kick ass!" Yang said.
"Sounds good to me!" Sarge said as the Chaos Emeralds surrounded them, but Rosalina took a step back.
"I do not need the Chaos Emeralds for a boost of power." Rosalina said as she closed her eyes. "That being said…"
BGM: Live and Learn (Sonic Adventure 2)
She raised her hand up in the air as a massive Grand Star appeared behind her. "It's time I no longer hold back." She said as she opened her eyes as they started to glow as a white aura surrounded her as the Chaos Emeralds surrounded everyone with Sonic glowing yellow.
"Oooh, Ibuki feels a new sense of power!" Ibuki exclaimed.
"Incredible…" Hiyoko said in awe.
"Alright! Let's knock some sense into this guy!" Sonic exclaimed as everyone started to lift off the ground and faced the giant Koopa King head on. Bowser would swipe at Summer and Ruby, but they would fly out of the way as they would both fly over and slashed at him as Sonic rushed over with Tails and Knuckles and slammed into his gut. Bowser breathed fire in retaliation, but Rosalina would put a stop to the flames by deflecting it as a massive comet came out of the Grand Star and shoot out and struck Bowser head on.
"Rrrgh!" Bowser growled as he would grab a hold of Tai and Qrow with his fist, but they burst out as Tai would punch him in the cheek where Qrow would then slash at him, then Gloria would fly over in her Latias form and unleashed a powerful Mist Ball attack before throwing out a powered up Draco Meteor attack. Bowser would try to bite down on Gloria, but she flew back right as Mario and Daisy would punch him in the face as Luigi would fly up and unleash an uppercut that snapped his head back. Bowser shook it off and breathed fire at the Mario Bros and Daisy, but they would avoid the attack as Amy would fly over Bowser with Nora as they both flew down and hammered him in the head with Cream & Cheese dive bombing him.
Bowser let out a growl and successfully backhanded the girls, but they would fly back as Ren would fire arrows at him and Penny fired lasers at him, where Marisa would join Penny by firing up a powered up Master Spark at him, then Susie would fire Drill Bits at him and Nitori would launch a whirlpool at him. Bowser would throw heavy punches at Penny and Nitori, but they avoided the attack as Rosalina rushed at him and delivered a powerful cosmic punch that knocked him back a bit.
"Don't worry, papa! I'll help you out!" Junior said as he tried to fire cannonballs but Mario would rush over and grab Peach from him while Pyrrha came over and burnt up his entire airship and knocked him toward a wall. "Gaaaah!" He yelped and let out a groan. "I'm okay!" He said as Pyrrha would join Jaune and Travis as they would fly over and slashed at him, with Jaune using his axe as Bowser grabbed a hold of Jaune with a smirk, but he was bombarded with telekinetic bombs, actual bombs and rockets from Nyx, Xena and Iris as Jade would shoot out an ice elemental attack to freeze his face but he shook off the ice as he saw Hiyoko flying toward her as he breathed fire at her but she turned into a boulder and slammed into his snout and jumped back while Ibuki, Weiss and Blake would fly over and slashed through him while also Ibuki firing powered up lightning bolts for good measure.
"Rrrgh…!" Bowser growled as he saw he was surrounded by danmaku. "What is this?!" He demanded to know as Reimu had her arms in an X.
"Fantasy SEAL!" Reimu yelled, as the Fantasy Seal exploded as Bowser let out a loud roar as Rosalina would follow up by throwing a small galaxy disc at him and threw it at him where he let out a pained roar, then Ilia and Byleth would slash through him, though the latter threw down her Amyr on him as Mercedes and Dorothea would shoot off powerful fire attacks, then Dorothea would whistle to get Zwei's attention as he came running, then launched a fireball at him as he launched over to Bowser and struck him in the gut to make him hunch over, then Pit and Palutena flew over and bashed him with a Upperdash Arm and Palutena's fist, then Bowser would feel the full wrath of the Forces of Nature where Viridi would smack his legs with powerful vines, then got hit by powerful lightning bolts and lasers from Phosphora and Arlon, while Cragalanche and the Dino Piranhas were pounding his feet with the Toad Brigade helping them out while the Blood Gulch crew, Carolina and Washington would be shooting him all over.
Rosalina clapped her hands together, making a cosmic sized javelin made with Star Bits as she threw it at Bowser, striking him in the chest right as Sonic and Ruby bashed into him one final time as he let out a loud roar before falling to the ground in defeat, coughing out the Grand Star in the process.
End BGM
"I'll take that." Rosalina said, grabbing the Grand Star as her eyes turned back to normal while everyone else did the same. The Chaos Emeralds attempted to scatter after being used, but Xena and Rosalina would catch them with their telekinesis.
"I don't think so." Xena chuckled as they were returned.
"Well done, everyone." Eggman applauded.
"Why didn't you do anything?" Yang asked.
"Battling physically isn't my forte… that and all my mechs are somewhere in the castle. Didn't feel like busting them out."
"…You just wanted to watch him get beaten up for ignoring you, is that it?" Sonic guessed.
Eggman chuckled, stroking his mustache. "Perhaps."
Viridi would let out a gasp. "Guys, look!" She said as they turned to see the large planet in front of them starting to grow in size.
"Oh my… it looks like we ran out of time." Eggman mused.
"WHAT?!" Everyone but Rosalina yelled.
"Indeed. We must hurry to the Observatory and quickly! I set up a shield where the black hole won't immediately spagghetify us. Rosalina will do her thing to stop this. We do not have much time! Hurry!" Eggman said.
"Will it work?" Ruby asked.
"It might! Now get going!" Eggman said as Rosalina teleported everyone to the Observatory as Eggman would immediately press a button as a powerful shield enveloped Peach's Castle, the Observatory and the Blue Typhoon right as the massive Star went supernova.
BGM: Luma (Super Mario Galaxy)
At Toad Town…
"Alright, smile and say cheese!" A Toad said, taking pictures of a Toad family when suddenly everything started to distort. "Wha…? What's going on?" He wondered as everyone in Toad Town was screaming and trying to hide as some objects lifted from the ground.
Willow walked out of the balcony of her home, looking at everything distorting around her as the sky was turning dark. "Mother!" Whitley exclaimed as he, Winter, Klein and Ling came running to her. "Everything's going out of whack!"
"…I think the universe is being destroyed…" She looked up in the sky. "Weiss…" She whispered as a tear ran down her cheek, while at the Belladonna's house somewhere else in Toad Town, Ghira and Kali looked into the sky before looking into each other's eyes before embracing each other.
At the Star Festival, Umber would look up in the sky as would Hau, Lillie and Guzma. "What's going on?!" Lillie wondered as Hau would see his Malasadas fly away.
"Oh man… my Malasadas are flying away!" Hau exclaimed.
"That's what you're concerned about?!" Guzma yelled.
Umber let out a sigh. "Well… and I had just made the perfect recipe too…" He said with a sad look on his face, while nearby, Marnie, Hop and Bede would look on in horror.
"Why is everything going to pot?!" Hop wondered.
"Is this… is this what Gloria's text message really meant?" Bede wondered.
Tears escaped Marnie's eyes. "Gloria… no…" She whispered as they started distorting as did the rest of Toad Town.
With Ghirahim…
"Hmm… unfortunate. Master Dry Bowser goes on an errand and the whole place goes down." He let out a hmph. "How unfortunate."
At Beacon Academy…
"Ozpin!" Glynda came running in with Port and Oobleck. "What is going on?!"
"It seems as if the whole universe is being ripped apart." Ozpin said, watching his window crack.
"What do we do?" Oobleck asked as Ozpin turned around.
"I am not sure." He said, the window shattering behind him as they started to distort.
Atlas…
Esdeath could watch on helplessly as everything around her started to distort. "Is this… is this truly the end?" She quietly asked, closing her eyes and pulling her hat down. "So this is it…" She whispered as she turned to her Winter Ops. "It's been an honor working with you."
Salem…
"My queen! What is this insanity?!" Tyrian exclaimed as Watts and Hazel could only look on.
Salem, however, smiled. "Is this it… is this truly the end that I have been longing for?" She asked and closed her eyes, accepting her fate as everything started to distort.
The Crimson Fang…
Adam and Seryu watched on into the sky while the other Crimson Fang started panicking around them. "So this is it." Adam said, his head still held high.
"It appears so." Seryu said with her arms folded and then let out a howl while everything distorted around them.
The Erdrean Monster Community near Bowser's Castle…
"This community is officially… open!" Captain Slime said, slicing the ribbon.
"Yeah!" All the monsters cheered… until everything started distorting.
"Aaaah! What's gooing on?!"
"This ain't good!"
Captain Slime sighed. "Welp… so much for the grand opening…" He mumbled.
At the Smash Mansion…
"CRAZY, WHAT DID YOU DO!" Master Hand yelled, watching everything distort around them while parts of the Mansion was being destroyed as some of the Smashers were being lifted off the ground.
"It wasn't me this time, I swear!" Crazy Hand defended.
"…So this isn't your fault."
"Nope…"
"Brother, I fear this may be the end."
"…Hold me brother!" Crazy said as the two hugged… as best as they could as the distortions would start affecting the other worlds like Erdrea, Shibuya, the Pokemon world, Norfair, Onett, Popstar and Gensokyo and other places.
Back in space…
Bowser would get up from the ground and see what was happening. "No! My galaxy… my empire… they were right all along!" He said as he fell on his knees, pounding the ground. "What have I done…" He silently whispered.
"Papa!"
Bowser let out a gasp and turned around, running over to Junior and hugged him tight as Kamek, General Guy, Neo and Roman would approach them and hugged him tight. "I'm scared Papa… what's gonna happen?"
"Don't look at it! Just hold on to me as tight as you can!" Bowser said, gripping Junior tightly as they started to distort.
With the others…
"The shield is failing rapidly!" Eggman exclaimed as the Lumas all gathered up around Rosalina.
"Now go!" Rosalina said as the Lumas saluted and then they flew off directly to the black hole, which also included the ones residing in Mario and Luigi's hat as they flew off right as the shields broke as the Lumas dive bombed into the center of the hole.
"This is it…" Ruby could only say, tears falling from her eyes as she would embrace her family as everyone embraced one another as they were sucked into the black hole as everything shrunk down as the black hole started to twist violently before shrinking down to nothing… and then, the black hole exploded into light.
And thus... ends the tale for literally everyone in the universe.
...Or is it?
Pffft, yeah, okay, even I can't make that sound convincing.
