BGM: Story of the Stolen Spirits (Paper Mario)
High above the Paper Mushroom Kingdom, there was this beautiful place called Star Haven where a bunch of Star residents lived in this beautiful area, and deep within Star Haven was a shrine, where the seven Star Spirits were watching over the Kingdom with a watchful eye, and also in the shrine was also the Star Rod.
It was just an ordinary day for these seven Star Spirits. They were none other than: Eldstar, Mamar, Skolar, Muskular, Misstar, Klevar, and Kalmar.
"I suppose that seems to be the case." Skolar said as they were in the midst of a conversation. "The Grimm do appear to be showing up more often."
"Indeed, but we can't do anything about it. The Huntsman, Huntresses and anyone who can fight are only the ones capable of it." Eldstar said.
"Yeah, but what about Salem? She's bad news!" Misstar said.
"We must not interfere." Eldstar said. "We can only grant wishes. We're not warriors."
"Indeed." Kalmar said. "We must however keep an eye on Salem if she ever makes her move."
"Speaking of bad guys, what do you think of that Dry Bowser fellow working with that dark blue team and that abnormal human?" Muskular asked.
"It is a very interesting team… but I suppose it's nothing to worry about. Unless they get that Ghirahim fellow involved." Klevar said.
"Indeed. We all must watch them closely." Eldstar said.
"One other thing. What's that next to the Star Rod?" Misstar asked as they turned to see something near the Star Rod… and then it suddenly exploded in smoke. "Aaah!"
"What in blazes?!"
"BWAHAHAHAHAHA!"
Bowser walked in to the Star Shrine with a smirk on his face along with Roman and Neo. "Heh, money well spent on those smoke bombs." Roman chuckled.
"Indeed." Bowser said as he walked over towards the Star Rod.
"HALT!" Eldstar ordered as he and the Star Spirits got in front of them. "We will not let you get past!"
"Kammy." Bowser cued and then Kammy Koopa appeared next to them, lifting up her wand and with her magic, the Star Spirits were all sucked into cards.
"There you go, your highness." Kammy said.
"I'll never understand why you brought that old bat out of retirement." Roman said.
"What was that?!" Kammy growled.
"She's the best Magikoopa there is. She may be old but she gets the job done." Bowser said as he grabbed the Star Rod. "Alright, bwahahaha! Time to have some fun with this thing!"

Meanwhile…
BGM: Toad Town (Paper Mario)
"Woooow! This house is amazing!" Ruby exclaimed.
"Ugh, it smells like pasta!" Weiss complained.
"You get used to it." Mario said as he had decided to show the girls his and Luigi's house.
"You guys live together?" Blake asked.
"Oooh! Cookies!" Ruby took off.
"Yeah, we do." Luigi nodded. "By the way, where's JNPR?"
"They went to go take care of some Grimm at Yoshi's Island. It turns out we missed a few and they went over to go take care of it with the help of Yoshi." Yang said as Ruby opened up the cookie jar and downed the cookies easily.
"Ah, that's understandable." Luigi nodded.
"I tried to invite Nyx, but she said she was too busy in her school work." Mario said. "Iris and Xena are nowhere to be found."
"Well, I guess it's just us." Weiss said.
"Mail call!"
"Oh, wonder what that could be." Luigi said as he walked out of the house to get it, and about a few seconds later, he came back in. "It's from the princess!"
"Oh?" Mario wondered as Luigi gave it to him as he took it. "Let's see here…"
"My dearest Mario, I'm inviting you to the castle for a special party! Please come, there's going to be a lot of refreshments. Oh, and please bring Luigi and Team RWBY. You can also bring JNPR, Nyx, Iris and Xena if they're not too busy with anything! – Love, Peach."
"A party?" Yang raised an eyebrow. "That sounds like fun!"
"Is it a formal party or is it a casual party? Personally, I'm more of the formal variety." Weiss said.
"PS: Please come as you are. You don't need to find a fancy dress!"
"Drat…" Weiss sighed. "I was hoping we'd get to change you three." She said, referring to her team.
"If it was formal, Mario and Luigi would've had to dress up too." Yang said.
"Never mind that. Let's-a go!" Mario said as they took off and hopped into a Warp Pipe, where they ended up in Toad Town soon after and they went straight to the castle.
"I wonder what this special occasion is." Blake said.
"Who knows, but I bet it's really gonna be awesome." Yang said as the Toad guards opened up the castle where they walked in.
BGM: Peach's Castle (Fortune Street)
When they walked in, they saw various knights and warriors in the castle. "Whoa… what the heck is going on here?" Ruby asked. "I don't recognize any of these people."
"Oh! Weiss!" A voice called out to Weiss as she saw a familiar girl waving her over.
"Lucina!" Weiss went over to her, and also saw Cordelia and Nowi as they started chatting things up.
"Except for those three." Ruby said.
"These people don't look to be from the other Kingdoms." Blake said.
"I've seen a few of them at the Smash Mansion, but… I don't know all of them." Yang said.
"I… don't think I can name them all." Mario admitted while Luigi laughed nervously as they walked around to mingle and getting to know them all… and that's when Peach opened up the castle doors.
"Hello everyone! Glad to see that you all came!" Peach grinned. "Now, I have invited you all for a very special occasion. From the kingdoms of Ylisse," She looked at the Ylisseans that were present… all except for two individuals. "Hoshido," She looked at the Hoshidans. "Nohr," She then looked at the Nohrians present. "And Lycia." She looked at the Lycians. "I propose an alliance with all of us! What do you say?" She asked.
Right on cue, there were a lot of cheering and clapping. "For those who agree, please sign the alliance paper on the table where Toadsworth is at!" She said, motioning over to Toadsworth who waved over to them… and right on cue, the royalty went over to him. "Alright, while that is getting signed, everyone have fun!" She said, followed by a lot more cheers.
She then looked at Mario. "Hey Mario, can you come here for a sec?" She asked.
"Sure." Mario nodded as he followed her deep into the castle while RWBY and Luigi hung out in the main area and chatted things up.

BGM: Peach's Theme (Paper Mario: The Thousand Year Door)
"What do you need, princess?" Mario asked.
"Sigh…" Peach sighed. "I've been planning this event for so long that it's been stressful. And normally, I'm not stressed!" She said. "I wanted to form an alliance with them so we can have strong allies. Not just with the Beanbean Kingdom, Sarasaland and Beacon Academy, you know?"
"I can see that. The more the merrier."
"Indeed." Peach nodded.
"So… what did you want to do besides tell me this?"
"Ah, I was planning on giving you something. Come here!" She said and wandered further as Mario walked after her… and that's when the castle started to rumble. "…Hmm?" She wondered before the castle started rumbling even further. "Wah! What's going on?! We don't normally get earthquakes here!"
End BGM
BGM: Bowser Jr's Airship Armada (Super Mario Galaxy)
Outside of the castle, and into Toad Town, the Toads were panicking. "What the heck is going on?!" One of them asked.
"It's the end of the world! I foresaw this!"
"Keep it together man, it's just an earthquake!"
"Guys, look!" A Toad pointed towards Peach's Castle to see it was being lifted into the sky by what appeared to be Bowser's Castle taking it up.
"Is that Bowser's Castle?!"
"I didn't know Bowser had an underground castle!"
"Everyone panic! It's the end of the world!"
"It's NOT the end of the world, moron!"
"Well, glad to see all those people are safe, considering they're running towards the square!"
Back inside the castle…
However, a few of them haven't escaped the castle… and that was RWBY. "What's going on?!" Ruby asked.
"No time! We need to rescue Peach and Mario!" Yang exclaimed as they took off, and when they came to Mario and Peach.
"Mario! Peach! Are you okay?!" Weiss asked.
"We're fine!" Mario said.
"…Oh my goodness!" Peach exclaimed as she looked out the window. "We're in space!"
"What?!" Everyone exclaimed in shock as they went over to the window and saw they were up really high.
"But… how? What's going on?"
"Guys, there's an airship coming!" Blake pointed as they saw an airship coming in and then parking near the window… and then Bowser, Kammy, Roman and Neo landed near them.
"Hello, you fools!" Bowser smirked.
"Bowser! I should've known." Peach said as Mario got in front of her, along with RWBY.
"Who's the old lady?" Yang asked.
"Old lady?! I'll have you know that I'm young, thank you very much!" Kammy said. "The name's Kammy Koopa, by the way, a good relative of Kamek."
"Where is Kamek, did he chicken out?"
"No, he decided to go on a vacation, so we asked Kammy to fill in for him." Bowser said. "But besides that!"
"Just give it up. We know this isn't going to change anything!" Ruby said.
"Oh, but this is very different than earlier, red." Roman said.
"What makes you say that?"
Bowser pulled out the Star Rod. "I have this to thank! Bwahaha!"
"The Star Rod?! But… I thought the Legendary Star Spirts were watching over it!" Peach exclaimed.
"Guess what? They weren't…" Neo said through a sign.
"And now I get to have all our wishes come true. Star Rod! Grant us our first wish… make us invincible!" Bowser ordered, and then the three of them glowed with a rainbow-like aura.
"Invincible my ass!" Yang exclaimed, jumping up and punching Roman and Neo, but her block was ineffective. "What?!"
"Ah ah ah, language! This is rated E for everyone, y'know." Roman said, pulling out his cane and shooting Yang point-black and then Neo ran in and kicked Yang a little harder than normal.
"Agh!" Yang winced.
"We'll see about that!" Ruby said, using her semblance and slashing the trio, but they were ineffective.
"Ha, that tickles." Bowser said and then backhanded Ruby away, while also blocking Blake's and Weiss's attacks as Neo ran in and proceeded to take them down easily. "Now it's just you and me, plumber!"
Mario growled, pulling out his hammer and running forward as he proceeded to hammer Bowser, but Bowser grabbed a hold of it and tossed him away. "Not this time, plumber boy!" He said, proceeding to snap the hammer in half before throwing it to the side.
"No! Not the hammer!" Ruby exclaimed. "You monster!"
"Oh, pipe down, you big baby!" Bowser said and raised the Star Rod up. "Star Rod! Make us more powerful!" He said and then they glowed a little, before he took a deep breath and proceeded to breathe fire as Roman shot them a few times as well, as all of the hits connected, making them all scream in agony before falling down in defeat.
"NO!" Peach yelled.
"AHAHAHA! YES! WE FINALLY BEAT MARIO AND THOSE ROTTEN TEENAGERS!" Bowser yelled as Neo suddenly took the Star Rod, and with a wicked smirk, she raised it up, and a few lightning bolts came down and blasted them all out of the window.
"NO! MARIO! RWBY!" Peach screamed.
"…Eh, that was a little too dark, don't you think?" Roman asked while Neo shrugged.
"This is E Rated after all, I was just gonna make them our prisoners, but hey, whatever works!" Bowser said.
"Now, let's get to business." Kammy said as they heard heavy footsteps approaching. "Oh?"
"We'll deal with them. You take Peach to her room." Bowser ordered.
"It will be done." Kammy said.

Meanwhile…
"C'mon, Chrom! We're totally late to that party!"
"I know where we're going. Besides, this is a shortcut."
"Shortcut, my foot! We're in the middle of a forest and you think this is a shortcut? Agh, I knew I shouldn't have trusted you with the map!"
"What's wrong with me holding the map, Lissa?"
"Um… exhibit A!"
"…Fair point."
THUD!
"What in the name of Naga was that?!" Lissa exclaimed.
"It sounded close. Come on!" Chrom said as he and his sister went to investigate the noise.
At the crash site…
On the ground were Mario and Team RWBY, unconscious… where the Seven Star spirits appeared before them… Well, mostly their images.
BGM: Star Spirit's Request (Paper Mario)
"Oh thank heavens, they're still alive! Gravely injured, but I know they'll recover." Mamar said.
"But alas, Bowser and Torchwick have the Star Rod, they're mightier than Mario and RWBY." Kalmar said. "Sigh, it's hopeless… all is lost."
"Everyone calm down." Eldstar spoke up. "As long as we keep it together, there's always hope. Now… our fates are in Mario and RWBY's hands. We must try to revive them. Gather round, send them your power!" He instructed as Mario and RWBY were glowing before they stopped. "Good… now that's all we can do. Mario, RWBY… please wake up!" He requested before they disappeared.
End BGM
"By the gods…" Lissa whispered as they got closer. "It's Mario and RWBY!"
Chrom immediately went by their sides. "Judging by their injuries, they look like they took a nasty fall."
"What do we do?" Lissa asked… and it was at this moment a female pink Goomba came by and noticed them.
"Hmm?" The Goomba came over to them and investigated them. "Oh my… judging by the looks of it, this must be Mario and Team RWBY… and you are…?"
"I'm Chrom."
"And I'm Lissa. We were on our way to the castle when Chrom got us lost… and then we saw these five unconscious."
"Hey!"
The Goomba giggled. "I'm Goombaria. We'll take these five to the Goomba Village nearby." She said and turned around. "Goompa! Goompapa! Come here a second!"
Chrom picked up Ruby and Lissa picked up Weiss. "Come on, they need all the help we can get."
"Right." Lissa nodded as they took off, unaware of what had happened from the skies above.
What, you thought it'd be Luigi's Mansion next? Ohohoho... you thought wrong! ...That's the next story.
Anyway, i'm gonna be having a lot of fun with this one and yes, the little stab at the Rated E will be made fun of through the Paper RWBY series. (Looking at you, Shadow Queen and Dimentio!)
Oh, and you Fire Emblem fans are gonna get a kick out of this story. Hehehe, trust me.
