Flopside (Super Paper Mario)

After Sabrina guided them to the last Heart Pillar, they walked to the top of the Flopside tower where the last door awaited them, and Merlon and Nolrem were waiting for them as well. "This is where we'll most likely meet for the final time if you do not succeed." Merlon said.

"We will all root for you, waiting for you to defeat Count Bleck and save the universes." Nolrem told them as they all nodded.

Sabrina looked at the door and clenched her fists. "Something wrong?" Sora asked.

"It's the point of no return." She said. "Once we enter this door, there's no turning back." She glanced at Yukari. "I don't think making a gap back here won't happen."

Yukari chuckled. "Which is why I gathered a lot of items while you were getting to the final Heart Pillar. There's no way I'd flee when our universes are at stake."

"Question." Natsu said. "Will a Keyhole bring you back?"

Sabrina shook her head. "I doubt it. Like I said, there's no turning back." She said and looked at them. "You guys ready?"

Sora smirked. "You forgot that I never run from a fight. I'm not gonna back down."

Natsu's fists ignited. "I'm ready to kick some major butt!" He said as the others nodded as well.

"Alright." Sabrina said as she placed her hands on the door...she looked like she was hesitating.

"You look like you're not so sure of yourself." Riku said.

"Truth be told...I never actually got to Castle Bleck on the Wii. For some stupid reason, my Wii keeps crashing whenever I attempt to play the last chapter of the game...so I never got to experience it."

"So that's why you're hesitating." Latias said as Sabrina nodded.

"Right...i'm not sure if some of us will make out alive or not."

"Ha!" Bowser chuckled. "You seem to forget that you got the King of Awesomeness in this party! We'll get through this easily!"

Sora (Kingdom Hearts II)

"And Fairy Tail!" Lucy pointed out.

"Don't forget the badass witch of Gensokyo over here." Marisa grinned.

"So what if you didn't get through your game? Big deal." Sora told her. "You'll get to experience it while not behind a TV screen." He said. "We might get hurt, but we got tons of healers with us. This will be interesting." He put his hand on his sister's shoulder. "And if you ever feel as if you're doubting yourself...just think of these words: 'My friends are my power'." He grinned.

Sabrina blinked before giggling. "I haven't heard that cheesiness in a while."

"Excuse me?" Sora asked. "That came straight from the heart!"

"Sabrina might be on to something..." Riku teased.

"Oh come on...you guys are worse than Donald and Goofy." Sora muttered.

Sabrina laughed before looking at the door. "Alright...let's do this." She said and looked at Sora. "Thanks, bro."

"Ah, no problem." Sora smiled as they all walked into the door.

World 8-1: Making an Entrance

Castle Bleck (Super Paper Mario)

They appeared in front of Castle Bleck, looking ominous and dark as always. "Well, that's certainly a big castle." Gray said.

"Oh please..." Natsu smirked. "We'll take it down like it's nothing."

"You're right." Link nodded. "We did destroy Bowser's castle in the Bitlands, so this castle should be easy to make a mess."

Bowser growled under his breath. "It was such an awesome castle too..." He muttered as Sabrina looked at the castle, as she visibly gulped.

"Hey, we'll do this together." Riku said as he was right next to her.

"Friends to the end." Kairi said.

"No matter what happens, we'll stick by each other." Sora said, as he was at Sabrina's other side.

"We're a team...and nothing will ever change that." Latias said.

Kirito and Asuna stepped in. "We will have each other's backs, no matter what happens." They said together as the others cheered them on.

"Let's take this castle down!" Natsu exclaimed and then they ran straight for the castle.

Inside the castle...

"O'Chunks! They're here and they're going to storm inside the castle!" A Goomba exclaimed.

"Then we must prepare a counter attack." O'Chunks said. "Get the Blastboxers to the doors and bring the Fire Bros and Boomerang Bros with you. Have the Shy Guys arm the Bill Blasters and gather as many allies as possible."

"Isn't that a bit overkill?"

"Overkill? No... it's the right amount." He folded his arms. "For you see...this is war."

"Fair enough." Goomba nodded and then ran off.

A few minutes later, the Blastboxers were at the doors, ready to attack them while the others got in position, as they heard a thump on the doors, followed by a loud bang as they got ready...and then the doors were launched from where they were, crushing the Blastboxers and a couple of Goombas.

Black Powder (Kingdom Hearts: Birth by Sleep)

Natsu and Captain Falcon were standing in the doorway with their fists just blazing. "We're here to crash this party!" Natsu exclaimed as pretty much everyone ran in the castle.

"Holy crap..." A Boomerang Bro sweatdropped.

"I didn't think the Heroes of Light would bring an ARMY!" A Fire Bro exclaimed.

"Stand your ground! We'll handle these guys!" A Shy Guy exclaimed as they fired Bullet Bills at the group, but they were easily taken out by Erza and Magnus while Phosphora flew around and shocked the Fire Bros and Boomerang Bros who were just frozen in fear.

"Uh, do we got any Banzai Bill Blasters?" Another Shy Guy asked.

"We do...but the Goomba told us to only get Bullet Bill Blasters!" The other told him.

"...Remind me to KILL that Goomba if we live..." The Shy Guy muttered as they were quickly overwhelmed by the party as several Koopas could only just look on in shock.

"Should we...uh...run?" A Koopa asked.

"Considering we don't have any weapons on us...yes." Another said as they quickly ran off, quickly dodging debris that Fairy Tail and the Gensokyo girls are making a huge mess out of...in fact, everyone was.

Where Count Bleck was at, he could feel the vibrations of the attacks that his castle is taking. "They have arrived..." He said.

"Shouldn't we...?" Nastasia asked.

"No...Let those fools come. Army or not, they will taste defeat." He said.

Back with the others, they were still making a huge mess as Bowser was breathing fire at his former minions. "Forgive me." Bowser said.

"Retreat! They're too strong!" A Gloomba exclaimed as they tried to run, but they were quickly impaled by sudden knives.

"You can't run." Sakuya said as they kept on going until O'Chunks landed on the ground in front of them.

"That's far enough." He said as they got ready to take him on. "I'd like to make a request." He said. "I would like to fight your strongest members in your party." He requested as Bowser, Magnus, Natsu, Erza and Falcon stepped forward.

"You guys go ahead." Magnus said. "We'll handle things here." He said as they nodded and took off.

"Good luck." Gaol told Magnus before taking off with the others.

"Let's get this party rolling!" O'Chunks exclaimed.

Rowdy Rumble (Kingdom Hearts II)

O'Chunks picked up a boulder and threw it at Natsu, but he fire punched it and instantly shattering it as Erza slashed O'Chunks and kicked him away where Falcon used Raptor Boost to launch him up in the air as Bowser jumped up to punch him down where Magnus slashed him away.

"You thought you could take on all five of us easily? You have another thing coming, pal!" Natsu told him. "FIRE DRAGON'S IRON FIST!" He yelled, punching O'Chunks to a wall where Bowser breathed fire at O'Chunks while Erza slashed him away after he tried to get up, as he was sent to Falcon who used Falcon Dive on him.

"YES!" He yelled after launching O'Chunks to Magnus who slashed him down to finish him off.

"Y-you...bested me..." O'Chunks muttered as Magnus chuckled.

"That was pathetic." He said when suddenly the whole place rumbled as the ceiling came down right on top of them, but O'Chunks managed to stop it.

"Go! Now! I can somehow manage to hold this!" He exclaimed.

"Oh no you're not." Bowser said as he held the ceiling. "You go!"

"You kidding?" Magnus held on. "You guys go."

"No way dude!" Natsu held on. "I'll catch up with later!"

"Natsu...you will go on...all of you." Erza held on to the ceiling. "Because I will hold on to this as long as I can!"

"Nuh-uh! You're not Gildarts! I should hold this!" Natsu told her.

"You seem to forget that I can hold my own." Magnus said. "If I can hold my own against Angel Face, then I have no problem with this ceiling!"

"And yet you had trouble with me at Sammer's Kingdom. I will hold it!" Bowser told him.

"As if! I will hold this up! I'm Captain Falcon for crying out loud!"

"No, I will!" O'Chunks told him. "All of ya need to leave!"

"Shut up, beard face!" Natsu told him as they kept bickering until eventually...the ceiling caved in.

World 8-2: Witch vs Koopa Wizard

Castle Bleck

"Did any of you feel that rumbling?" Sabrina asked.

"You don't think..." Gaol looked behind, looking really worried.

"If I know Erza and that Fire Brain, they would've gotten out of there." Gray said. "Still...I can't help but shake the feeling."

"They're alright...I hope." Sabrina said as they kept on going.

"That's far enough." A voice said as they saw a lone Koopa Wizard in front of them.

"Kamek!" Mario exclaimed.

Kamek smirked. "This is as far as you will go." He said. "For I will destroy you before you destroy the rest of this castle."

Suddenly, Marisa growled under her breath as she walked forward. "I have no idea why...but the way I look at you just burns me up." She said. "Looking at you makes me sick."

"It's strange...it feels as if we have met somewhere before." Kamek said. "And that feeling disgusts me."

"I don't remember you two meeting." Reimu said. "Is this some sort of game?"

"No." Marisa shook her head. "It doesn't feel like it. It feels like we've met and argued for the longest time. I feel like we need to settle it..."

Kamek summoned his wand. "Bring it, witch." He said.

Yukari folded her arms. Is there a universe where these two constantly bicker? She wondered before shrugging it off.

"You sure you can handle it?" Sabrina asked.

"Yes...now go." Marisa told them as they took off...except for Reimu. "Reimu..."

"I just have this feeling that I should just watch." She said.

"Alright, but if a stray danmaku bullet hits you, don't come crying to me." She said as Reimu rolled her eyes.

Vessel of Stars ~ Casket of Star (Touhou 10.5: Scarlet Weather Rhapsody)

"Magic Sign: Milky Way!" Marisa exclaimed, but Kamek fired bolts of lightning to stop the danmaku as Marisa flew over through the smoke and whacked Kamek with her broom, knocking him a few feet before he teleported and then fired a fireball and hit Marisa from behind.

"Freeze!" Kamek shouted, firing a couple of homing icicles at her, but she flew out of the way.

"Ritual Sign: Orreries Sun!"

Kamek growled under his breath and fired fireballs at her, but she flew up as she fired simple danmaku at him, but he teleported to the side. "I don't get it, we have never met each other in our entire lives...but yet it feels as if we've been enemies for such a long time." Marisa said.

"It sure feels like it." Kamek nodded. "It might even be a coincidence..." He muttered.

Reimu blinked. "How come I'm not feeling a connection to this?" She wondered as she watched Marisa and Kamek keep on firing magic and danmaku all over the place. Is there a universe that has these two constantly fighting? I might need to ask Yen Sid when we get back to our universe...

"Light Sign: Luminous Strike!" Marisa called out as Kamek yelled in pain as he retaliated by firing a bolt of lightning from above, causing Marisa to scream in pain. "Why do I feel nostalgic?" She wondered.

"Don't look at me...I don't know WHERE this feeling came from." He said. "Like I said, it's probably just a coincidence." He said.

"Whatever." Marisa said. "Light Blast: Shoot the Moon!"

"I don't think so!" Kamek yelled as he fired a couple small lasers to block the danmaku and causing small explosions. "This should end things." He smirked as he fired a bolt of lightning through the smoke, but there was no scream. "Huh?"

"Right here!" Marisa exclaimed as she flew right towards him...and she was surfing on her broom as Kamek's eyes just widened in shock. "SUNGRAZER!" She yelled and went through Kamek.

Reimu winced. "Oh, that's gotta hurt."

Castle Bleck

Marisa chuckled and hopped off of her broom. "I don't care if that was overkill. I feel like he got what he deserved for whatever reason." She said as they walked to catch up to the others.

Kamek weakly got up. "I don't...think so..." He said and then fired a small laser at a chandelier right above Marisa, causing it to fall.

Reimu noticed this and her eyes widened. "MARISA, LOOK OUT!" She screamed as she dove and pushed Marisa out of the way, then Marisa heard a loud crash before she landed on the ground.

"Wh-what the heck was that...?" Marisa wondered as she looked and her eyes widened in complete horror. A chandelier was right on top of Reimu with tons of shattered pieces of the chandelier everwhere...but Reimu wasn't even moving. "REIMU!" She screamed as she went over to her.

Roxas (Kingdom Hearts II)

"Don't you die on me!" She told her as she tried to push the chandelier off of her. "Come on!"

"Heh..." Kamek held on to his arm in pain. "I don't know why...but she deserved it. In fact... that's a good look for her."

Marisa glared at Kamek, her eyes filling with tears. "How dare you..." She said as she ran up to Kamek and grabbed him by the throat. "YOU ROTTEN BASTARD!" She yelled and threw him to a wall, as he grunted in pain but Marisa still held on to him, punching him repeatedly. "SHE WAS MY BEST FRIEND! SHE WAS A PRINCESS OF HEART!" She couldn't control her tears as she stepped back and aimed her Hakkero at Kamek.

"Killing me will not...bring her back..." Kamek said.

"I don't give a crap about that!" She told him and clenched her fists. "Magicannon: Final Spark..." She said as Kamek was engulfed in the humongous laser, completely obliterating him as the laser disappeared before she went over to check on Reimu.

"Come on..." Marisa looked at her as she pushed the destroyed chandelier off of Reimu and held her close. "Reimu...don't you dare leave me..." She said as her tears were falling nonstop. "You can't leave me! You're my best friend! You don't need to go out like this!"

Reimu wasn't saying anything, but tears were landing on her cheek. "Reimu..." She sobbed. "Come back..."

Meanwhile...

Villains of a Sort (Kingdom Hearts)

"Argh..." Mimi fell on two knees. "I can't believe...what just happened."

"Maybe you should think twice before you go dissing Fairy Tail." Lucy said, looking pissed off while Kairi used Curaga on herself, Peach, Rosalina, Lucina, Samus and Asuna.

"Hmph..." Lucina put Falchion away. "What a little brat." She said and suddenly the castle rumbled again as the floor started to give away.

"Oh crap!" Lucy exclaimed as she took out her whip and grabbed on to the ledge as everyone started grabbing onto the whip.

"We gotta start climbing!" Rosalina told them.

"You don't have to tell US twice!" Asuna exclaimed.

"Little girls first!" Mimi said as she tried to climb up, and she was about to reach the top but suddenly, Dimentio picked up the end of the whip. "Dimentio! Don't let go! Pull us up!"

Dimentio looked at the ladies and then at Mimi, as he smirked. "I am sorry, Mimi...but you are useless." He said and then let go of the whip, hearing the girls screaming on their way down. "Ahahaha...more people eliminated." He said as he teleported to a different area of the castle.
