Bowser's Theme (Paper Mario: The Thousand Year Door)

"So, where the heck are we now?" Bowser asked.

"Poshley Heights." Kamek replied.

"You think we can vacation here one day?" Junior asked.

"Probably not." Bowser said as he looked at the civilians cowering in fear. "Knowing our reputation, we probably wouldn't be greeted with open arms." He said as they walked around.

"Hey, I wonder if the Crystal Star is in there." Hammer Bro pointed to the Poshley Sanctum.

"It could possibly be in there." General Guy said as they soon discovered the Poshley Sanctum locked up with a brand new lock. "Oh, it's locked."

Bowser smirked. "Not for long." He said as he pulled back his arm and punched right through it, knocking the doors completely off of its hinges.

"Nice one!" Hammer Bro grinned as they walked in and saw a Crystal Star right in front of them.

"Aha! We've finally found one!" Junior exclaimed as they immediately ran up to it and picked it up.

"Oh baby, we've finally got one!" Bowser smirked. "I knew we'd get one eventually!"

"And yet…you still haven't." A voice said as they turned to see Pennington casually walking up to them.

Pennington (Paper Mario: The Thousand Year Door)

"What are you talking about? This is a Crystal Star." Bowser said.

"It is indeed…but it isn't."

"What do you mean 'It isn't'?" Kamek pointed his staff at Pennington. "Tell us right now before I-"

"It's a red herring." Pennington calmly told them. "The real Crystal Star are in the hands of Mario and friends."

"OH COME ON!" Bowser yelled as he threw the Crystal Star to the ground, completely destroying it.

"You do realize you're going to have to clean that up, right?" Pennington asked.

"Just how many Crystal Stars do they have by now?! This is unbearable!" Bowser growled.

"Lord Bowser!" A voice called out as a Paratroopa came flying in through the window. "We have news!"

"What is it?" Bowser grumpily asked.

"Mario and company have all seven Crystal Stars and are now headed to the Thousand Year Door as we speak."

"Alright…that's it. I'm not going to let them get to that treasure first." Bowser said. "Come on, guys. We got a plumber to fry."

"And his friends!" Hammer Bro added as they walked away.

"Hmph…is it too much to ask for people to clean up after themselves?" Pennington asked as he grabbed a broom and dustpan. "I mean, honestly, villains should pick up after themselves too, y'know…"

Back with the others…

X-Naut Fortress (Paper Mario: The Thousand Year Door)

"So, is everyone here?" Yukari asked.

"Not everyone." Nitori replied. "Link, Cloud, Youmu and Minene are still missing."

"I wonder where they are." Rosalina said as a surprisingly working elevator opened up as Cloud walked out.

"Hey guys? You might want to come see this." He said as they looked at each other and Yukari made a gap to go down to the lowest floor of the base where they saw Youmu and Minene leaning on different walls while Link was folding his arms as they walked in.

Organization XIII (Kingdom Hearts II)

"O-oh…y-you're…Mario, Luigi, Fairy Tail and friends…correct?" TEC asked.

"You must be TEC." Erza replied.

"Indeed…I am…"

"Dude, why are you so…worn out?" Natsu asked.

"It's because…I was forcefully shut down by Grodus…but the emergency generator kicked in right when they left…but even that's…failing…" TEC muttered. "You…came for Princess Peach, correct?"

"Crump said that she wasn't here when we took him on." Mario said. "He said that she was taken to the Thousand Year Door."

"Crump was correct…she has been taken there by Lord Grodus…to…finish what he started…"

"So it was Peach that I heard…" Cobra mused.

"You heard Peach?" Gajeel asked.

"I couldn't tell if it was her or not, but she did call out for Mario, so I assumed it was her." Cobra explained. "But, I didn't say anything because what if it was a trap and not actually Peach?"

"That's actually not a total bad guess." Worldwalker said.

"I would've thought the same thing." Youmu said.

"Yeah." Link nodded.

"You…need to save Peach…before it's too late…" TEC told them. "And…tell her…that…I'm thanking her for…everything she's done for me….while she was here…"

"We will." Natsu nodded. "You can count on it."

"Thank you…I assume you have an exit plan…to get to her as quickly as possible?"

"Yes." Yukari said and made a gap.

"Good…" TEC said. "This…is probably it for me…farewell…." He said and then the X-Naut Fortress went completely red.

"Poor thing…" Lucy sighed.

"We can grieve about him after we've saved Peach." Minene said, pointing to TEC's screen that is counting down. "He's taking this place with him."

"Don't you worry, TEC…we'll get Peach back." Mario said as they went into the gap.

Outside of the fortress…

"Rosalina, we have to leave. That place is about to blow and it might just take the Observatory with it." Polari said.

"Right." She nodded as the Observatory powered on and took off, as they watched the X-Naut Fortress explode.

"So, do you think Peach is alright?"

"I can't safely assume that she is…but I know Mario and his new friends will save him. The other me will save her too."

"Got it. So, we're heading back to the Mushroom Kingdom?"

"Yes." She nodded.

"Alright." Polari nodded.

Cody…don't let me down. Rosalina thought.

Rogueport Sewers (Paper Mario: The Thousand Year Door)

"Ever had one of those moments where you think you've heard someone tell you something after you leave?" Worldwalker asked.

"Not really." Nitori said.

"Did you have that?" Luigi asked.

"Maybe." He said and looked away. "It was probably the Rosalina from this universe telling me something."

"Well, whatever it was, I'm sure I'm…I mean…she's cheering you on." Rosalina said as they started walking.

"Well well well, if it isn't Mario and friends!" A voice exclaimed as they saw Frankly walking up to them.

Professor Frankly (Paper Mario: The Thousand Year Door)

"Professor Frankly!" Goombella exclaimed. "What are you doing here?"

"Oh, just waiting for you to arrive because the seal of the Thousand Year Door is about to break and I want to see it first hand."

"…Okay." Mario nodded. "Lets-a go!" He exclaimed as they took off to the Thousand Year Door.

The Thousand Year Door (Paper Mario: The Thousand Year Door)

"Alright, here we are. Let's open this door!" Frankly said.

"Now HOOOOLD on a second, whippersnappers!" A voice called out as they looked to see a portal opening up and Dyntos walking in.

"Lord Dyntos?" Worldwalker blinked. "Uh, what are you doing here?"

"Well, I want to give Miss Scarlet a new armor that holds the power of the Crystal Stars."

"New armor? I'm listening." Erza said.

"Yes, this new armor will be the best armor you'll ever have. It may just even rival the Nakagami armor. There is just one thing I need."

"What is it?"

"Dragon bones from Bonetail. He is in the Pit of 100 Trials." He said.

"Did you say dragon?" Sting asked.

"I did." He nodded as he pointed to the entry way. "The entrance is through there."

The dragon slayers looked at each other as they nodded and quickly ran to the entrance of the Pit of 100 Trials. "Hey! I want to see a dragon for myself too!" Minene went after them.

"Wait up! I want to see it too!" Youmu flew off as the Mario Bros took off after her and then Erza quickly followed.

Worldwalker blinked and looked at Dyntos. "Why do I have a bad feeling about this? You've probably tampered with the Pit of 100 Trials, haven't you?"

Dyntos chuckled. "Perhaps I did…perhaps I didn't."

Hades chuckled. "This ought to be entertaining."

"I happen to bring a screen along so we can all watch their progress." Dyntos said, as a screen popped up in front of them.

"Well alright then." Lucy said as they sat down and watched.

"Does anyone have any food?" Yuyuko asked.

"So…this is the entrance, huh?" Natsu asked. "A single Warp Pipe."

"Let's go." Gajeel said as they all went in.

One Who Gets in Our Way (Xenoblade Chronicles)

Floor one: A few Goombas, a Koopa and a Shadow Heartless

"Out of our way!" Natsu said as he punched the Koopa to the ground while the Mario Bros hopped on the Goombas and then Youmu fired danmaku at the Shadow Heartless to eliminate it and then they went to the next floor.

Floor two: Bob-ombs, Pigmask Soldiers, a Soldier Heartless

"FIRE DRAGON'S ROAR!" Natsu yelled, already blowing up the Bob-ombs while Erza slashed through the Soldier Heartless.

"SKY DRAGON'S WING ATTACK!" Wendy yelled, blowing the Pigmask Soldiers away and then Cobra obliterated them with his roar.

Floor Three: Fly Guys, Shroobs, ReDeads, Piranha Plants

"Agh!" Wendy exclaimed as a ReDead got on her as a Shroob aimed at her, but it got annihilated by Laxus and then Minene kicked it off of Wendy while Erza slashed through the Piranha Plants. "Thanks." She said and used her roar on the Fly Guys.

A couple of Shroobs circled around Gajeel, but then he smacked them away with his club and then they continued onward.

Floor Four: Motobugs, Mettaurs, Flages

"Where are they?" Natsu looked around for the Flages as they appeared behind him, only to get annihilated by Rogue and Sting as the other enemies were no match for Laxus and Erza.

Floor five: Kracko, Waddle Doo, A Shy Guy

Kracko was below Laxus and fired electricity down below. "Heh, thanks for charging me up." He said as he jumped up and punched him down where Wendy blew him into a wall and said wall exploded with Minene's explosives, destroying Kracko while the Waddle Doo and the Shy Guy were eliminated.

Floor Six: Metal Man, Large Bodies, Dodongos

"Whoa!" Luigi ducked through the Metal blades. "Take it easy, will ya?!" He exclaimed while Youmu slashed Metal Man away.

"Hmph…not bad." Metal Man said and threw more metal blades, but Youmu easily blocked them and slashed right through him while the Dodongos were blown up by Minene while Natsu and Gajeel easily took care of the Large Bodies. "You're quite troublesome…" He muttered as he threw more metal blades, but Youmu blocked them and then slashed through him again to defeat him.

"You're quite the pushover." Youmu said as they went to the warp pipe, but then noticed Gajeel eating the remains of Metal Man.

"What?" Gajeel asked.

Floor Six: Three Mimicuties

"Blasted treasure chests!" Natsu said as he fire punched them. "You aren't allowed to run away like that!" He said as Laxus punched the ground really hard, creating a shockwave to knock them to the ground…and they were quickly blown up by Minene.

"Now I have trust issues with treasure chests." Minene growled.

Floor Seven: Galoombas, Spinies, Boo

Luigi sucked up the Boo and smirked. "Piece of cake." He said as he saw the Galoombas and Spinies getting annihilated by Sting and Cobra, and then they continued onward.

Floor Eight: Bonkers, Shadow Heartless, Waddle Dee

"FIRE DRAGON'S IRON FIST!" Natsu yelled, punching Bonkers away while Erza took care of the Waddle Dee and the Shadow Heartless, and then Bonkers hammered Natsu away.

"IRON DRAGON'S CLUB!" Gajeel yelled, punching Bonkers several times before jumping back and then Mario hammered him on the head and it was annihilated by Rogue's Shadow Dragon Roar

Floor Nine: Yellow Devil

"Man, this is so annoying!" Natsu growled. "How many times have we hit it?!"

"I think a thousand times…" Gajeel said.

"I don't think we're hitting it right." Laxus said. "We're hitting the body, but I don't think it's doing anything."

"So what do you think we should do?" Minene asked.

"Simple." Laxus said as his fist charged up and punched Yellow Devil right in the eye, causing it to explode when hit. "We hit the eye."

"I think you just murdered it with just one punch." Sting sweatdropped.

Meanwhile…

Have a Nice Talk (Mario and Luigi: Bowser's Inside Story)

"Figures…" Dyntos said. "Yellow Devil is an annoying boss, but it seems that recreation was no match for Laxus."

"I knew you had changed it up." Worldwalker sighed. "I just knew it."

"Even I had a hard time with Yellow Devil on Mega Man's stage and Laxus just goes and kills it with one punch." Link muttered.

"All of this fighting is making me hungry." Yuyuko said.

Back with them…

One Who Gets in Our Way

Floor eighteen: Darknut, Syren, Paratroopa

"REQUIP!" Erza yelled as she went into Purgatory armor and then slashed the Dark Nut while Wendy had kicked the Syren down while Natsu punched it to the wall while Mario punched the Paratroopa to the ground and then Luigi hopped on its shell, and then he kicked it towards the Dark Nut right when Erza destroyed the shield and the armor as it slashed upward to knock Erza in the air.

"WHITE DRAGON'S IRON FIST!" Sting yelled, punching the Dark Nut in the back and sent it flying towards the wall and then Laxus destroyed it.

"Thanks." Erza nodded as they went into the next room.

Floor nineteen: Mecha Sonic

Erza blocked Mecha Sonic's bullets with the Adamantine Shield and then Mario hammered Mecha Sonic away. "Hmph!" Mecha Sonic charged up a spin dash and unleashed it right at Mario, knocking him to a wall but Minene caught him. "It is useless!"

"Don't underestimate us!" Natsu said. "FIRE DRAGON'S IRON FIST!"

Mecha Sonic caught it. "Hmph!" He said as he threw him to the side, but then was hit by bullets from none other than Minene. "Is that how you want to play it?" He asked as he fired at her, but she flew around and keeping him occupied as Laxus raised his hands up in the air.

"LIGHTNING DRAGON'S HEAVENWARD HALBERD!" He yelled, unleashing it on Mecha Sonic as he looked directly at it as he tried to dodge, but it was too late…he was engulfed in it and caused him to explode…and just like Metal Man, Gajeel ate his remains and then went on to the next room.

"What the heck is that?!" Wendy exclaimed as they saw a big monster in front of them.

Room twenty: King Dodongo

Volvagia/King Dodongo (The Legend of Zelda: Ocarina of Time)

"I don't know, but its dead meat!" Natsu said as he ran over to it and punched him, but King Dodongo shrugged it off. "Oh, immune to punches? Then how about…" He jumped back. "FIRE DRAGON'S ROAR!" He yelled, but not even that stopped it as it opened its mouth and breathed fire, but Natsu ate it up while Sting and Rogue jumped up.

"WHITE DRAGON'S IRON FIST!"

"SHADOW DRAGON'S CLAW!" They both yelled, but it didn't seem to leave a dent as Laxus roared at the beast, but even that scratched it.

"You have got to be kidding me." Laxus said as danmaku bounced off of King Dodongo.

"The armor is too thick!" Youmu exclaimed and then King Dodongo rolled straight for them.

"SKY DRAGON'S ROAR!" Wendy yelled, attempting to push him back, but it was no use as it then unrolled itself and opened his mouth.

"GRENADE OUT!" Minene yelled and threw it into his mouth, and once it exploded, King Dodongo roared in agony. "…Are you serious?"

"Explosion on the inside? I know what to do now." Natsu said as they waited for him to open his mouth, and when he did… "FIRE DRAGON'S BRILLIANT FLAME!" He yelled as King Dodongo ate that thing up as it exploded inside of him and roared in agony.

"One more should do it." Minene said as she pulled out some C-4 and when King Dodongo opened his mouth again, she threw it in there and pressed the button, as it exploded and King Dodongo roared in agony before falling to the ground and poofed away.

Have a Nice Talk

"You mind telling me what the heck you were thinking when you put in Mecha Sonic and King Dodongo?" Worldwalker asked.

"Hey, they need to have a challenge every once in a while…besides, it's fun." Dyntos chuckled.

"Oh brother." Worldwalker sighed. "What's next?"

"I'm not telling you, it's a secret."

"Figures." He sighed.

One Who Gets in Our Way

Floor 25: Tailbunker, Chandelure, Plasma Wisp

"TAKE THIS, YOU DRAGON!" Natsu yelled, punching it to the ground and then Youmu slashed through it while Mario hammered the Chandelure to the ground and then Luigi used a charged Luigi Missile to take out the Plasma Wisp…but he was blown away by a fully charged plasma shot.

"Ow…" Luigi groaned as the Plasma Wisp was taken out by Cobra and Sting and then the Tailbunker was defeated by Erza slashing through the body.

Floor 26: Kritters, Soldier Heartless, Goomba

The Kritters attempted to bite down on Wendy, but Natsu and Gajeel protected her and punched them away while Wendy finished them off with her Wing Attack while the Soldiers got eliminated by Minene and Youmu while the poor Goomba got stepped on by Mario.

Floor 27: Paragoombas, Wigglers, Robo Eggs

"FIRE DRAGON'S ROAR!" Natsu yelled, frying up the Wigglers and Paragoombas while Laxus and Erza took care of the Robo Eggs.

"This is getting easy." Gajeel smirked.

"I wouldn't get cocky." Laxus said as they continued onward.

Floor 28: Invisibles, Mettaur, Koopa Troopas

Hell Flame Sword: Flashing Slash Formation of Karma Wind. Youmu thought and slashed through the Heartless while Erza already took care of a couple while Mario and Luigi kicked the Koopa Troopas away to the others, knocking them to the ground while the Mettaur attempted to stay hidden, but Gajeel picked it up and annihilated it.

"I'm telling you, this is easy…" Gajeel cockily smirked as they went into the next floor.

Floor 29: Koakuma

"Koakuma?" Youmu asked.

"I don't even know how I got here, but…" Koakuma got in a position. "You're here to fight me…so give me everything you've got."

"Right." Youmu nodded as they ran forward to Koakuma as she took out a spell card.

Thank goodness Patchy gave me a couple of these. She thought. "Metal Sign: Metal Fatigue."

"That's not metal!" Gajeel exclaimed as he dodged It as Mario and Luigi used Knockback Bros to knock her away, but she immediately recovered and then kicked away Minene who flew straight for her.

"Earth and Metal Sign: Emerald Megalith." She said.

"That's not metal either!" Gajeel growled in frustration.

"SKY DRAGON'S CLAW!" Wendy yelled as Erza slashed her several times while Youmu fired danmaku at Koakuma.

"Fire Sign: Agni Shine High Level!"

"Now THAT is fire!" Natsu said as he ate it up, much to Koakuma's surprise.

"But you can't conjure up metal? What a bunch of bull!" Gajeel exclaimed. "IRON DRAGON'S ROAR!" He yelled, causing Koakuma to hit a wall.

Koakuma fell on one knee and clenched her fists. "Not done yet." She said while panting. "Water and Wood Sign: Water Elf."

"You're just making this stuff up! That looks nothing like a water elf!" Natsu exclaimed in annoyance as Minene appeared behind Koakuma and kicked her away and then Natsu used an uppercut on her as she hit the ceiling and fell to the ground in defeat.

"Sorry about this, Koakuma." Youmu said as they went deeper into the pit.

Have a Nice Talk

"I seem to recall Koakuma never having spell cards." Nitori said.

"I went out of my way to give her some spell cards." Dyntos said. "But I made her think Patchouli gave her those."

"Interesting." Worldwalker said.

"Well, let's see what happens next." Hades smirked.

I was originally gonna have the Pit of 100 Trials all in one chapter, but..knowing how long it took to write? I decided to split it into a couple of parts, otherwise...i'd be writing this one single chapter all freakin' day long and i'd go crazy!

Also, Koakuma may or may not be the only Touhou boss in there. *laughing evilly*
