In the skies above Peach's Castle in the Mushroom Kingdom…

"Orraaaah!" a roar said as a battle was being held on a giant flying ship. Mario, the hero of the Mushroom Kingdom, was battling his lifelong nemesis, Bowser, aboard his ship. Bowser was wearing a white tuxedo with purple accessories and a large top hat, and he just missed slamming Mario into the deck. After missing a jumping slam, he launched a fireball that made Mario dodge, as all the while Princess Peach watched.

Elsewhere in a place that was eerie and filled with fog, the heroes were watching as a brutal beatdown was going down as Sanji was kicking the living daylights out of Luffy.

"Come on, fight back dammit!" Sanji shouted.

"I won't!" Luffy shouted as he kept taking each kick, even losing a tooth on one of them.

"This is crazy…" Ty said.

"Jexi, can't you do anything to stop this? Sanji's gonna break Luffy's skull open!" Hope said.

"This isn't a fight between teammates. It's a battle between captain and subordinate. I have no right to interfere." Jexi said.

"This is more like a beating. Luffy isn't even fighting back, what's he even trying to do here?" Connor asked.

"It's because Luffy cares about Sanji that he isn't fighting back. Raising even a fist against Sanji is the same as saying he doesn't want him back." Spectra said.

"I'd say Sanji could care less about what Luffy thinks right now." Ty said.

"This is very different from when you fought Luffy, was it Usopp?" Petra asked.

"Yes. When we fought, it was over my ideals...but this...this is Sanji trying to keep Luffy and us out of this trouble." Usopp said.

Luffy was sent back by another hellacious kick.

"I won't ask again… get out of my sight, Luffy." Sanji said.

Luffy only rose his head as Sanji growled as he started ascending high into the air.

"No, he can't do that… Luffy, get outta the way!" Hope said.

"You heard him, move!" Gemini said.

"Shut up! I won't move! I'll take it all!" Luffy shouted.

"Diable...Jambe!" Sanji said as his leg ignited as he then descended while spinning with said kick.

"I can't watch!" Erica said.

"Concasse!" Sanji shouted as his kick landed right on Luffy's head. After it had hit, Luffy shook for a bit before he collapsed to the ground unconscious. Sanji only stared at the unconscious Luffy. "Goodbye." he said as he headed back to a carriage with 66 on it.

"So, you done with those peasants now?" said a blue haired man wearing the same clothing as Sanji.

"We're done. They won't bother us again." Sanji said getting in.

Back on Bowser's Ship, Mario lost his hat as bowser had him cornered.

"This is the end… for you!" Bower said throwing his hat like a boomerang that smacked mario overboard as bowser stepped on his hat.

"Mario!" Peach shouted.

"Hehehahahahah!" Bowser said grabbing Peach. "It's time for my wedding with peach to get underway. Jealous, Mario?"

Back in the same place, Luffy was slowly getting up as Sanji and his family departed. "Sanji...I know...that you don't want this! I'm not moving from this spot! I won't eat or drink anything! Hear me? I won't eat anything cause the next thing I want is something you cooked!" Luffy shouted as the carriage was going out of sight.

"Damn… I dont think Luffy's been serious about anything like this." Natsu said.

"It just shows how much he cares about his crew." David said.

"So is that really it? Are we just gonna leave Sanji to get married and have Luffy starve to death?" Gemini said.

"If you ask that, then you clearly don't know us." Jexi said.

"He's right. There's no way we'll leave him at the mercy of that monster, for lack of a better word." Sectonia said.

"Then it's settled. We'll leave luffy here, and go after Sanji, even if we have to chase his trail all over the globe until we get to Whole Cake Island." Connor said.

"Whole Cake isn't even on this world." Betty said.

"Seriously, Connor. We just got Hope up to speed on this." Kokichi said.

"Yeah, that's ri… wait, HEY!" Hope said.

"Anyway, let's touch down and see what the situation is." David said.

"I'm a little worried about Luffy in the state he's in. Someone should stay behind so that he doesn't do anything reckless." Lloyd said.

"He's declared to sit in that one spot and not move or eat. What's the worst he could do?" Asta said.

"Okay, did you seriously just ask that?" Toma asked.

"Yeah, that kind of question is just a sign of bad luck." Tapu Koko said.

"He's right. Think I better keep watch over him." Dan said.

"I'll go too." Aelita said.

"Aelita?" Jeremie asked.

"Dan and I first met Luffy when we were starting out on our first adventure. Even if Ichigo and Davis aren't here, at least the two of us should watch him." Aelita said.

"We're the closest things to siblings to him. We're going without an objection." Dan said as the two of them left.

"Keep him safe you guys…" Hope said.

The heroes left the area from where the heartbreaking fight occurred. Spying a village up ahead, they went to it, but not far off from it, they saw Mario, unconscious, with a small, blue hat like ghost holding his ripped cap right near him.

"Is that… Mario?" Hope asked.

"It sure looks like it… but what's with that hat-ghost thing?"

"Someone's gotta get a read on the situation. Hey. Excuse us." David said.

"Meep!" the ghost squeaked as he bolted off.

"Great, I scared him." David said.

"Hey, up an at em Mario." Hope said touching the famous Plumber as he bolted upright, still riled up.

"Whoa whoa, easy! Were not with Bowser!" Toma said.

Mario ignored this as he chased after the small ghost before it soon stopped in its tracks.

"Ah...good. You stopped. You should be glad I saved you back there." the ghost said.

"Okay...start talking, ghost." Kazuichi said.

"Yes. My name is Cappy. And I was chasing this monster's ship to save my sister, Tiara." he said.

"Why would anyone want your sister?" Hope asked.

"Because of Bowser's wedding. God, I forget how slow you are sometimes." a voice said as a figure stepped out of the shadows. "Still...it wouldn't be you if you weren't slow." they said.

"Jack?" Jexi said.

"And not just me. Some old friends decided to tag along for the ride." Jack said.

"I think that's probably our cue to say…" a familiar tomboyish voice said as a girl and a boy came out behind them. "Didja miss us?"

"Oh hey, Rainbow." most of the Dimensional Heroes said nonchalantly.

"Seriously?! Ugh. I am not gonna try to be dramatic with you guys." Rainbow said.

"Jesse, it's good to see you again. I see your hair's spiked up a bit since you left. You're looking sharp as ever." David said.

"Thanks, sorry to have worried you." Jesse said spotting Dark Metaknight. "Uh… Dave? I know I don't question your judgment, but...what is he doing here?"

"Long story, but let's just say Symonne got Seraphnapped." David said.

"By Big Mom, I'm guessing. Starting to make sense why you'd come here." Jesse said as he spotted Francisca. "And who's the girl? Did you and Sectonia have a kid while I was gone, or something?"

"Yeah, I wish." David said. "This is Francisca, my pupil."

"Bonjam. It's nice to finally meet you. The others told me a lot about you." Francisca said.

"Speaking of...why are you guys here? I thought you were training at the Coalition." Indigo said.

"Yeah...about that. We sorta had a mini war in the Future Universe and it sorta...lead to the Coalition being shut down." Rainbow said.

"Shut down?" Connor said. "That can't be really what happened, that place seemed so bright in the future."

"It was...till we sorta….pissed off Cyan." Rainbow said.

"You pissed off, Cyan?!" Madoka said. "She's hardly ever mad."

"So uh.. What happened that got her so off her rocker?" Ty said.

"Our war took place on a place called Junkyard Planet. But it turned out to be a secret cultivation world for her. She was so pissed we wrecked it...she attacked a large portion of us." Rainbow said.

"She almost destroyed us until the president of the Coalition intervened. Him and Louie, they were talking with her. She agreed to let it go on several conditions. One of which was the disbandment of the Coalition." Jesse said.

"Damn… Good thing we left when we got the chance." Kaito said. "What about everyone else?"

"They'll be fine. Just split up and most returned to their homeworlds. Other stayed in Neo City. But...there are no more Blessed or Errors." Rainbow said.

"Man, that all sounds like you've been through an apocalypse." Hope said. "So, what brings you to the Cap Kingdom, my theif of a brother? I thought you were out stealing from the Combat Revues."

"Yeah, that turned out to be a bust. I needed something better...then I found out about the weddings here and decided...I'm gonna rip off both of them." Jack said.

"Speaking of weddings, you're all going after that one monster, right?" Cappy asked.

"Yes we are." Jexi said. "Big Mom is one thing but Bowser is another."

"Then were both after the same thing. Why don't we work together to save Tiara and Peach?" Cappy asked.

"I was going to propose the same thing." Jesse said.

"Hey, Jesse. How about getting your butt back on the team?" Ross asked.

"I would propose that as well. The team just isn't the same without you." David said.

"Same with you, Rainbow. Come back with us." Jexi said.

"Duh, why else would we be here?" Rainbow said.

Mario, nodding at the sight of the heroes coming to help, was ready to get back on his quest. But he noticed his hat was still missing and ruined.

"Oh, right… your cap." Cappy snickered as he glommed himself on Mario's head. "Not the same huh? No worries." he said fusing himself with the remains of Mario's hat before landing right on his head.

"Okay...first of all...where are we?" Lacy asked.

"The Cap Kingdom, home of tradition, prosperity and hats. This is its capital, Bonneton. A land of haberdashed dreams." Jack said.

"I can see that, considering all the damage…" Brandish said looking around.

"That was caused by Bowser… and of course every airship here is in shambles." Cappy said.

"Maybe there's one you and Mario could use the next kingdom over?" Sora asked.

"Yeah… yeah, there is one in the next kingdom! I could get Mario over there, but that would mean scaling Top-Hat Tower, and Bowser's Henchmen are still up there." Cappy said motioning to a small ship spraying confetti and playing some sort of music.

"So, what are we waiting for then?" Hope said before Jack grabbed him.

"Hold it, brother. Im not leaving here until ive got what i came for." Jack said.

"Uh.. i don't think Bonneton has anything worth stealing…" Cappy said.

"I'm sure there's…" Jack said before seeing a ship landing nearby. "Damn it. He followed us."

"He followed you? Who followed you?" Hope aske before seeing the Universal Police insignia. "Oh, no… you finally got some five-o on your tail, huh?"

"Afraid so. I knew this would happen eventually. See...I need to take on a disguise for now." Jack said before going to a damaged store before coming out in a black suit and top hat with his mask no longer being worn.

Out of the shuttle came a male officer.

"Greetings, officer. What can we do for you?" Connor asked as the officer showed his badge.

"Quit showing off that phony badge." he said slapping it out of Connor's hand. "I am Carapaccio. An Inspector from the Universal Police. I'm on the trail of a thief called Jack. I know he's on this world."

"Jack? I'm sorry to say Carapaccio… but uh, we don't really know the guy." Connor said.

"Don't bother lying. I know you worked with him in the past." Carapaccio said.

"Oh come on, we were working together to stop Diablo from… ah, never mind… he was cleared of his charges any way." Connor said.

"No he wasn't." Carapaccio said. "He's still wanted for thievery from multiple universes. He's looking at a lifetime in prison. Just because you're some washed up bounty hunter doesn't make you an official of the law."

"Washed...up?" Connor said in disbelief.

"Seeing as how he isn't around here...think I'll look around town for a bit. I'm not letting him get away." he said walking off.

"Washed up… the nerve of that guy!" Connor said.

"That's what impacted you the most out of this?" David asked.

"That was an insult to my pride, okay?" Connor said.

"Just come off it. I'm considered to be a washed-up tennis player, and you don't see me crying about it." David said.

"Plus what he said is kinda true. I mean when was the last time you caught an actual criminal...on your own?" Indigo said.

"Yeah, you're probably right…" Connor said. "Let's just get to Top Hat tower before that Inspector realizes anything."

"Before that, weren't you looking for someone here, Jack?" Rainbow asked.

"I wasn't looking for anyone. Just grabbing some souvenir's. Ah...wait, that's right. I'm looking for someone to help my plans. An escape artist that escaped from that stupid prison that blew up." Jack said.

"Considering what Big Mom and her cronies are capable of, I'd say you'd need one." Zelos said.

"Yeah. He's an escape artist dubbed the Escape Master. He was last seen here. Now I only need to...wait." Jack said before spotting a human man with some bags in the town before he stopped the moment he saw them. "There he is!"

"Ah crap!" he said dropping the bags as he took off.

"I'll get this guy. Check this out. Zone Speed!" David said slowing time to a stop before he shot something at the man before making him fall. "Got him. Wait, what?" he said as the man started digging before digging through the ground.

"Damn...guess there's a reason he's called an Escape Master...but there's no way he'll go far." Jack said seeing the ground coming up as it went towards the tower.

"Oh no, that's where Bowser's henchmen are! We gotta hurry and stop him!" Cappy said.

"Right-o!" Jesse said. "By the way, Dave. That was an amazing move you pulled! Since when could you do that?"

"Just recently. Ryoma's been teaching me how to use it." David said.

"By the time he'll perfect it, it'll be the ultimate countermeasure against him." Ty said.

"You're referring to Katakuri, right? I sure hope that'll be the case." Jesse said.

Going inside Top hat tower, the group scanned the area.

"Where's the Escape artist?" Sora asked.

Donald looked around before seeing him climb up the ledges. "There he is!" he called.

"Crap." he groaned as he started swinging himself grabbing each ledge quickly before reaching the top and running out the door.

"Damn, he's good…" Ty said. "How the heck are we supposed to top that?"

Cappy noticed a few frogs hopping around. "By the looks of things, you guys could clear those easy, but Mario needs a bit more spring… hey Mario, throw me at one of those frogs."

"Okie-Dokie." Mario said throwing cappy as he latched on to one of the frogs.

"Umph! There we go. Cmon!" Cappy called as Mario was immediately sucked into the cap. After a moment, the frog gained a mustache and the same eyes as Mario.

"Whoa! Thats cool!" Chopper said.

"Pretty neat huh? I can latch myself onto anything, enemy or otherwise, and Mario can take control of it. I call it Capture.. Get it?" Cappy asked.

Mario was then hopping up each individual platform as the group followed by climbing each one. They soon reached the top of the tower where the guy was cornered.

"Damn...no way out." he said before seeing them approach.

"In all fairness, you really should've come up here in the first place." Sting said.

"Oh yeah...we'll...I do have a last resort." he said standing on the edge. "Let me go or I drop to my death."

"You're not serious, are you? We just wanna talk." Ty said.

"That's what all hero types say." he said.

"Look, before you jump to any conclusions, note that we're not here to hurt you. A companion of ours has a favor to ask of you." Sectonia said.

"A favor huh?" he said.

"I'm stealing from two massive weddings and I need a master escape artist." Jack said. "I need your skills. So please help me." Jack said.

"Hmm. Fine. On the condition I don't get arrested afterwards and get half the profits." he said.

"Done." Jack said.

"Wow...that was...dramatic right dere." a voice said as they saw a small ship with four rabbits in there. "As for us, we happen ta be da planners of Bowser's wedding. We're called...the Broodals!" said the shortest of them.

"A quartet of rabbits are Bowser's wedding planners?" Ty said.

"At least the name is original." David said.

"Oh snap! Lookie here, buds! Actual Lunarians!" said a larger rabbit in back.

"People from the moon, just like us." the tallest rabbit said.

"So what if they're people from the moon. We still gotta stomp them out." the shortest one said as he jumped out. "The name is Topper and you'll be...on bottom." he said throwing his hat at them.

"Whoa!" Gemini said as the hat was dodged.

"We already got what we came for in dese parts, so there's no reason to stick around. But.. da boss said roughin' up mustached creeps and deyre pals was on the contract, so i still got some work to do!" Topper said spawning three more hats on top of his head.

"You're gonna be sorely disappointed in your results then." David said.

"Yeah...especially considering these are just top hats." Jack said tossing two knives at two of them before kicking one of them at Topper as it collided and sent him flying far away.

"The Broodals, huh? Those guys are gonna be a pain." Ty said. "But hey, David. It must be pretty weird knowing there are other moon inhabitants other than Lunarians."

"Not really. Trust me, you'll see why when we get the chance to return to Cecil's world." David said.

"But in any case… we've got work to do!" Cappy said. "See that island over there? Thats the Cascade Kingdom. Its where we'll find us a ship to help keep up with you guys."

"We'll meet you over there. Hopefully we'll be able to chase both Bowser and Sanji this way." Ty said.

"Right." Jexi said. "Off we go then."
