Ronan1511: Dude, you are psychic. How did you know? *laughs* I jest, it's obvious i'm gonna do Wrath of Xehanort next. ;)
"Ugh…" Natsu groaned as he sat up and rubbed his head. "The heck did I eat last night…?" He wondered to himself as he heard footsteps coming down the stairs. "Hmm?"
"Wakey wakey!"
"…What the… what the hell are you doing here?!" He yelled, getting off the bed and igniting his hands. "You part of the Organization too?!"
"That's right." Xigbar smirked.
"Tell me, you trying to kill me in my sleep?! Well guess what, pal! It's not gonna work!"
"Whoa, Natsu! Take it easy!" Lucy walked in. "He's with us… for now at least."
"…Come again?"
"Yeah, he's here on behalf of Xehanort. He's going to help us destroy the Shadow Queen."
"What… are you sure?"
"Yes."
Natsu glared at Xigbar. "What are you planning?"
"What, can't a guy join in on the party? I've had enough of Queenie just as much as you guys." Xigbar smirked.
"We have all the Crystal Stars too. We can end this once and for all." Lucy smiled.
"…But do we have to side with him?"
"Unfortunately, yes… I'm not liking it either, but it's how it's gonna be for a while."
"You gotta be…" Natsu glared at Xigbar. "You try anything funny and I'm going to roast you!"
"Heh, well we wouldn't want that now, would we?"
Natsu walked off, giving Xigbar a glare before walking up the stairs to get on the deck. "So, we got all the Crystal Stars?"
"Yup! Now we're heading off to Gensokyo to finish this once and for all." Marisa said.
"That's good." Natsu said and then looked over to see Ashe, Junkrat and Roadhog. "Who are those three?"
"Let's just say… acquaintances." McCree said.
"Very… explosive happy ones." Demoman said. "You thought I was explosive, you never met that crazy lad."
"They sure are a rambunctious bunch, I'll give 'em that." Piers chuckled.
"Let's face it, we're just a bunch of misfits attacking the Queen of Death herself!" Scout said.
"Personally, being with you guys is a lot more fun than attacking you all." Zero said.
"Oh really?" Dedede looked at him smugly. "Can we get it in writing?"
"Don't make me pound your face in."
"We got a mission to do!" Soldier said, cocking his shotgun. "Beat Shadow Queen's commie ass to the ground! Let's move it, ladies!"
"Yeah, what soldier boy said." Xigbar chuckled as they headed off for Gensokyo.
Meanwhile, in Gensokyo…
BGM: Have a Nice Talk (Mario and Luigi: Bowser's Inside Story)
"Ooooh, okay, I think I see what's going on here." Hat Kid nodded. "This Shadow Queen lady is destroying everything you guys love and you're going to use these pretty hearts to revive everyone once we destroy her?"
"Precisely." Lea nodded.
"Welp! This Heart brought me to you guys, so let's do it!" She grinned. "So, where do we find this peckneck? In a tall, dark and obvious evil mansion? In space? Underground?"
"Youkai Mountain. That is where we need to go." Sanae said.
"Oh, on a mountain. That works too!"
Right on cue, a portal opened up as they turned to see the airships coming in as they gently landed on the ground as one by one, everyone hopped off. "Yo!" Marisa called out.
"Well well well, the calvary has arrived." Lea chuckled.
"Goodness, isn't that a bit much?" Demyx sweatdropped.
"You can never have too many soldiers in a war." Xander said. "And besides, we are facing a great threat. The bigger the army, the better."
"What the… two more!" Hilda exclaimed.
"Alright, I'm going to knock their heads off!" Lysithea declared.
"Take it easy." Sakuya walked over to them. "They are on our side." She said and then spotted Xigbar. "…What is he doing here?"
"Can't a guy change sides temporarily so we can destroy the Shadow Queen together?" Xigbar smirked, and then saw Lea approaching him. "Ah, hey hot head."
"I don't know what you're planning… but I don't like it." Lea said, grabbing a hold of Xigbar's collar. "If you try anything funny, so help me, I will shove a chakram into your chest."
"That might have worked on Vexen, but it won't work on me." Xigbar smirked. "Besides, I'm here on behalf of the old man to tear Queenie apart. She went beyond Xehanort's agenda so I'm here to join all of you in tearing her into pieces."
"Oh, I see, you're going to destroy her so you can get back to where you morons left off. I see how it is." Lea said. "I already know you're gonna betray us in the end, so I'm not sure what the hell you doing here is going to change anything."
"You know, it says something that even the bad guys we're facing is tired of the Shadow Queen's antics." Reimu said. "So we have to form an alliance with this guy… even if he's completely shady. If they want to help, then so be it."
"You have a point… but I'm keeping an eye on you." Lea glared and then let go of Xigbar.
"So, if you don't mind me asking…" Shantae chimed in. "Who are you guys?"

One long introduction later…
"Now that we have gotten introductions out of the way." Ryoma said. "We scale Youkai Mountain."
Chrom walked forward. "It shouldn't be too difficult, but the fights will be tough."
"Yes, but we all have the same goal. The Shadow Queen." Yusuke said.
"I don't know about you, but I'm ready to end this." McCree smirked.
"Good lord, they're multiplyin'!" Ashe complained. "Now we got lobster head sounding like McCree!"
"When will it end?" Ryuji groaned.
"Will you two be quiet! It's nothing to worry about!" Lucy said.
"Yeah, no need to overreact over this!" Makoto said.
"Lucy and Lucy 2.0 are right." Happy said. "We need to destroy the Shadow Queen, not worry about who has the same voice!"
"Lucy 2.0?" Makoto repeated with a raised eyebrow.
"In any case, we have one goal in common, and that is to destroy the Shadow Queen." Byleth said. "Some of us may not get to her alive, but with our strength combined, we will put a stop to the Shadow Queen no matter what."
"Together, we will triumph." Edelgard said.
"Yeah! Now let's blow Shadow Queen's commie ass sky high, ladies! We got a job to do! FOR AMERICA!" Soldier yelled.
"Geno, you better not slow me down!" Bowser said.
"I could say the same thing to you." Geno said.
"LET'S GO!" Marisa yelled, hopping on her broom as she and Reimu led the charge to Youkai Mountain with everyone charging right behind them.
Up on Youkai Mountain…
"Oh, cute. They think they can stop me with that little army?" Yukari chuckled. "Destroy them." She ordered, sending Heartless and Wizzerds down Youkai Mountain.
BGM: Final Destination (Super Smash Bros Brawl)
"Here they come!" Marisa called out.
"Get ready!" Ryoma exclaimed as the Wizzerds came flying down and multiplied, firing lasers at the gang where Reinhardt and Brigitte interlocked shields and blocked the lasers from hitting them as Soldier rocket jumped in the air and fired rockets as Pharah did the same, both of them firing rockets together and hitting the Wizzerds. Wyvern Heartless came flying over to the two to try and attack them, but Erza came flying over in her Heaven's Wheel Armor and slashed through the Heartless while D. Va bombarded them with missiles.
Marisa aimed her Mini-Hakerro and fired a Master Spark, but some Wizzerds teleported out of the way and fired lightning bolts, only to get hit by other lightning bolts courtesy of Shantae and Kairi, the latter having to use Thundaga. Dark Balls came flying toward them, but were quickly destroyed by Link and Luminary. Some Youkai looked up from their hiding spots to see what was going on and were cheering for everyone running up the mountain.
"How are they still…?! Gah!" Yukari growled, sending more Heartless and Wizzerds down to stop them, where Camilla threw her axe at a Wizzerd and then Meiling flew over and kicked the axe further into its body to kill it, then tossed the axe back to Camilla where she caught it and smiled, then a torrential roar hit a Dark Ball that was coming down on the two. They turned to see Kamui waving at them with a smile. Bea ran past them and delivered a flying knee kick to a Soldier Heartless, then delivered a round house where Gloria's Cinderace destroyed it.
Youmu flew through and slashed through Wizzerds as one shot a laser directly at her but Genji got in the way and deflected it back, hitting it directly as it fell over. Youmu nodded at Genji as they continued to climb as Alice flew up in the air and fired lasers from above while Patchouli unleashed a Solar Flare with Makoto to create an opening for them to get through the blockade of Heartless as Gajeel and Wendy released a Roar to cause the Wizzerds to go flying and were quickly skewered by Zero's blood needles.
"Argh! Alright… you leave me with other choice." Yukari said, watching them get closer. "Oh Poisontail! Meal time!" She called out as she walked into her lair.
"There she is!" Bowser said as they got to the top and then they charged at the mansion… when suddenly Poisontail slammed into the ground in front of them.
End BGM
"Fools! You have made it this far, but you will die by me!"
"Ha!" Natsu cockily laughed. "We defeated your two siblings! What makes you think you can take us down?"
"Hmhmhm, foolish Dragon Slayer. You will think twice before getting cocky with me. I am Poisontail, the ultimate dragon of the Pit of 100 Trials! You fools will die by my poison!"
"Bring it on, dragon!" Reinhardt declared as everyone got ready for combat.
"Let's get this party started! AROOOOOOOOO!"
BGM: One Who Gets in Our Way (Xenoblade Chronicles: Definitive Edition)
Poisontail tilted his head to look at the sky and breathed a toxic gas, as it formed above the gang before it started raining. "Gah! It's acid rain!" Impa said once a drop hit her on the shoulder.
"SKY DRAGON'S ROAR!" Wendy yelled, blowing the Acid Rain Cloud away. "That should buy us some time!"
Meta Knight quickly flew over and slashed at Poisontail with Zero, as Poisontail headbutted them to knock them back as Rosalina fired a huge energy beam from her wand which Poisontail took it in stride as he walked over to the cosmic space queen and attempted to stomp on her, but she teleported away as Viridi sent thick vines out from the ground and wrapped around Poisontail, but the latter broke free of the vines and breathed a toxic gas at the goddess as she rolled over to avoid it, but Poisontail knew she would roll out of the way and breathed another toxic gas and hit her dead on.
"Gah!" Viridi yelped.
"Viridi!" Shantae exclaimed as she quickly turned into a bat to get up into the air before transforming into a tortoise, flipping herself over and slamming into Poisontail's head, then hopping off while hitting him with a lightning bolt.
"Get me up in the air!" Hat Kid requested while Marisa fired a Master Spark.
"You sure?"
"Trust me!" Hat Kid grinned as Marisa nodded and pulled out her broom, letting Hat Kid ride on her broom… and when they were above her. "Alright, here we go!" She smirked, putting her top hat away in favor for a snow beanie and hopped off, transforming into an ice statue and slammed hard into Poisontail, enough to make Poisontail yelp and then Hat Kid hopped off.
"…Huh! That kid's got style." Marisa mused, watching Hat Kid pull out an umbrella and fired a laser directly at him.
Poisontail glared at Hat Kid and breathed a green fire at her, to which Erza got in the way and used her Adamantium Armor to block it with a shield. The shield started to disintegrate on contact as Erza's eyes widened. "The flames are corrosive!" She called out. "Someone get us out of here!" She requested as Tracer blinked their way.
"Hang on!" Tracer said, holding on to Hat Kid and blinked to safety and grabbed a hold of Erza and did the same thing, right as the shield had melted away as the flames hit the ground and hit a few trees, knocking them to the ground. "Phew, just in time!" She smiled as she started shooting at Poisontail along with the other gunmen, whittling away Poisontail's health while the latter was laughing at their pitiful attempts. He raised his right front leg and slammed into the ground, as poisonous steam geysers popped out and hit Sakura, Takumi, Demoman and Lea, but Serena quickly use Omniheal on them to keep them going, with Kairi tossing a few Megalixers to get rid of the poison.
"Cool it!" Veronica yelled, unleashing Kacrackle on him as Erik unleashed Ridgeraiser on Poisontail, with the spiked rocks hitting him but the dragon didn't really seem to care.
"Eiga!" Joker called out, using it on him to whittle some health while Luminary called upon the Diamond Star for assistance, swinging his sword down as crystal spikes rose from the ground and slammed into Poisontail, piercing him as he let out a pained roar and then breathed another toxic gas in the air, having corrosive acid rain fall to the ground as Ryoma and Chrom charged ahead and slashed at the dragon, as it attempted to bite down on the two, forcing them to jump back as Robin and Dorothea unleashed a Thoron attack while Marisa unleashed an aura attack.
"You fools! I've just been toying with you!" Poisontail laughed and then flew up in the air, getting hit by the Dragon Slayers Roars and Gajeel's Iron Club, but he didn't really care as he looked down and smirked wickedly. "POISON SMOG!" He yelled, breathing a toxic smog throughout the area, hitting everyone directly and covering them in a thick smog.
"Nnngh! What is this?!" Reimu said.
"Don't breathe it in!" Patchouli yelled, unleashing Jellyfish Princess on herself and casting a spell to try and block everyone's airways as quick as she could… until Poisontail slammed directly on her to bury her.
"PATCHY!" Meiling yelled.
"We'll be having none of that!" Poisontail smirked, breathing his corrosive fire breath that hit Reinhardt, melting his armor on contact as he looked up as he saw D. Va firing missiles at him as he breathed fire, but she did a barrel roll to avoid the attack as Bowser went into his shell and rolled to him, slamming into his face while Junior closed the Koopa Clown Car for his protection and fired cannonballs at him where Geno unleashed Geno Whirl on him, throwing a disc. Poisontail smirked and gobbled it up. "Mmm, tasty!" He said, and then Geno snapped his fingers as it exploded inside of him. "Mmph! …What's that supposed to be, heartburn?"
"What?!" Geno yelled as Bea had her Machamp try to pick up the poison dragon with his arms. Poisontail smirked and secreted poison from his scales, hitting Machamp's arms as it let out a yelp and jumped back while Jade and Serena both used Crushed Ice on him.
"Hah… hah… I'm not… giving up…!" Viridi weakly said, as the poison smog was doing a number on the goddess as she ran over to Poisontail who had swatted away Edelgard, Dimitri and Hilda. The dragon spotted the weakened goddess as he smirked and added another poison breath attack on the goddess, ignoring the shield throw by Shield Knight and Shovel Knight smacking his head with his shovel. "GAAAAH!" Viridi yelled, falling on both knees. The poison was enough to destroy Viridi's headband and her ponytail fell into her more natural flowing hair.
"Viridi!" Sanae exclaimed before clapping her hands and unleashing Moses's Miracle on Poisontail, slamming into him while Juvia saw her chance as she manipulated the water danmaku and shot it directly at Poisontail with Nitori backing her up, then Suwako unleashed Lord Long-Arm and Lord Long-Leg, the lasers hitting Poisontail directly.
"Fools!" Poisontail breathed his poisonous fire once more, forcing the others to get out of the way, but the poisonous smog was making them sluggish, the fire just barely grazing Engi and Torbjorn, but it was enough to destroy their sentries.
"Cana, don't you have a card that can clear this damned smog?!" Natsu yelled.
"I do!" Cana nodded, pulling out a card. "Purification Blast!" She yelled, tossing the card to the ground as it sprayed a mist that cleared the area of the poisonous smog.
"Hmm… impressive." Poisontail mused, before feeling something underneath him. "Hmm?"
"Get. OFF!"
A hot watery geyser sprayed underneath Poisontail, powerful enough to get the dragon flying as Patchouli got up and dusted herself off as she flew over to avoid getting crushed again. "Now's not the time for sleepin' on the job!" Xigbar said, firing bullets at the dragon.
"Shut it!" Patchouli glared, healing herself up as Rosalina called upon a Star Storm to rain down on Poisontail as Yuyuko unleashed Eternal Sleep in Dreamland, hurting Poisontail as Lysithea unleashed Dark Spikes onto him.
"Nnngh… you're troublesome, I'll give you that… it's time for my ultimate attack. My lady warned me not to use this, but if it's enough to destroy all of you… then so be it!" Poisontail laughed as he began to glow brightly.
"What's he doing now?" Gray asked.
"TOXIC… CORROSIVE… BLAAAAAST!" He yelled, unleashing a powerful explosion that would have covered them all… if it wasn't for Viridi's quick thinking and summoning a sunflower dome to protect her allies, getting hit by the toxic air, but she stood strong, making sure her friends were well protected.
"Nnngh!" Viridi winced. "I… I may… despise… humans… but there are some humans… that are worth… protecting!" She declared, seeing some of her flowers were decaying as she made more to protect them all.
End BGM
Once the poison had lifted, Poisontail fell limp as the sunflower wall dissipated. "Heh… at least… I got one of you…" Poisontail weakly said as his scales were decaying and melting, slowly turning back into Bonetail.
"You didn't even kill us!" Marisa said. "What kind of poisonous dragon were you? You failed!" She taunted.
"Heheheh… while it is true that I didn't kill all of you… at least my poison did wonders on one of your allies. As long as I got one of you… I succeeded." Poisontail smirked. "Farewell, heroes… good luck on defeating my master. I doubt… that you will pull it off." He smirked, closing his eyes before his scales melted away, turning back into Bonetail as his bones started to fall apart and crumbled.
"What…" Marisa turned her head, seeing Viridi down on the ground. "Oh no…" She said as they ran over to the fallen goddess as Rosalina gently cradled her.
BGM: Roxas (Kingdom Hearts II)
"Viridi… why didn't you protect yourself?"
"Mmm… it's because… I was nearly dead anyway." Viridi coughed. "Poison affects me greatly… because I'm a nature goddess… and the rest of you aren't… it is true that I hate humans… but some humans are… worth protecting."
Gloria took off her bag, opened it up and reached through it. "Come on, come on… where's a Pecha Berry? There's gotta be one in here! Marnie! Do you have any on you?"
Marnie dug through her pockets. "…I unfortunately don't. I used it on my Liepard."
"My Machamp needed it desperately, that was the only ones I had."
"I wasn't going to let Obstagoon die like that." Piers said.
"Snorlax wasn't looking too hot… sorry mate." Hop rubbed the back of his head.
"No… SHITE!" Gloria yelled, punching the ground in frustration.
"Don't… don't try to heal me…" Viridi said. "I protected you from the poison… now go… and destroy the Shadow Queen… if you dummies revive me now, my sacrifice would've been for naught…"
"You… you sure you don't need healing?" Serena asked.
"No… this was my choice… and I'm going… to go out my way…"
Hanzo closed his eyes. "Our meeting may have been brief, but you have battled with honor. You deserve rest."
"Go… save everyone… before it's too late…" Viridi said. "And… Rosalina… I'm… sorry I treated you… way back… then." She said, taking her last breath before falling limp.
Rosalina took a deep breath and gave her a sad smile. "I forgive you, Viridi." She said, covering her eyes and closing them, gently putting her down on the grass as Serena pulled out her lyre and played a tune as Viridi's soul flew off.
"Yggdrasil… please watch over the Goddess of Nature." She whispered.
"Let's go." Reimu said. "We've got a battle to finish. Shadow Queen is waiting for us on the other side… and we'll have to fight for our lives, no matter what she throws at us. For everyone that died trying to stop her… for the entire world… let's go."
"Lead the way." Byleth requested, and with a nod, Reimu and Marisa walked into the lair with everyone following her. Kairi stopped and looked at Viridi's body lying on the ground.
"We'll take her out soon." She whispered and then walked into the lair, the doors closing behind them.
Ya know, the sad thing is... I wasn't really planning on killing off anyone else on the good side, then I realized that... realistically, Viridi wouldn't have made it out of the Poisontail fight alive when I was writing the battle. So here I was like "Shoot, I thought I was done killing them off. Oh well..."
