Spoilers from included and/or represented works abound. Please read this fiction carefully.
"Who's these two girls?" The Sentais and the Rangers have no idea of what they just saw.
"It's Miss Amaterasu, and her servant..." Lucy is scared.
"It's Hirume the Seventh Heaven, and Yomi." The two Queens recognized both girls.
Hirume and Yomi is bounded and gagged, and mouth taped. They helplessly wiggled around inside the cage.
"Blackmailed ya!" A voice echoed.
"It's you!" Queen Nia recognized the voice. "Rigna the Bloodrunner!"
"Those idiots of Yaoyorozu deserved to be jailed." Rigna appeared.
"How could you!?" Queen Melia sadly asked.
"Welcome, Rangers!" Lord Drakkon appeared.
"What!? The evil me!?" Green Ranger is shocked. "Not him again!"
The Sentais and the Rangers are shocked at the appearance.
"Who wants this crystal?" Lord Drakkon then brought up the red-and-lemon-green crystal, the Super Hero Time crystal. "By the way, this crystal controls the Grid as well!"
"As for me..." Rigna then holds a blue crystal that glows red, the Square Enix crystal. "With this crystal, Chaos isn't even anything but a literal joke!"
"Those two crystals!" Queen Nia noticed.
A Sideways Rift appeared on top of and in behind the Sentais and the Rangers.
"As expected." Rigna spotted the rift. "Let's ready to destroy you, the Sentais!"
"Not gonna lie, but we're going to defeat you both!" Lucy told Drakkon and Rigna.
"I can destroy multiverses now." Drakkon replied. "And with that and the blessing of the Bloodrunner, I will destroy you!"
"For the sake of Empress Zero... It's time tomake it right."Rigna declared. "We will break your worlds, and we will tear down everything that might protect anything you have."
"And then when it's all over, for real and for good, when you become utterly powerless, totally alone and truly dying, you will all realize the truth:" Drakkon continued."...with all your potentials and possibilities that you don't know you can handle, any of you could've been gods."
"Fuck you!!! We protect the peace in our Earths! And everything we hold dear, not treating everything apart for no reason!!!" Zenkaiser profanely responded. "Without us, peace on our Earths surely would have been destroyed for good!!!"
"Seems like you idiots have limited visions." Rigna is disappointed at Super Sentai.
"You imbecile! Prepare to be destroyed!!!" Drakkon is ready to fight.
"Shut up, you motherfuckers! We will protect our Earths and save our multiverse, and so much more!" Zenkaiser ready to fight. "Are you ready, Super Sentai!?"
Right afterwards, all Sentais and Rangers transformed and then fought two menaces. Their teamwork was pitted against the brutality that Rigna and Drakkon possesses. Every single Sentai furiously striking Drakkon and Rigna. Every single Power Rangers striked both threats in rage and fury. All for sake of peace in their worlds and more.
"Pretty good, you doll-ish!" Rigna as he's continuously attacked by all. Everytime he counterattacks, another Rangers jumped to strike him.
"If you hope to defeat me and save yourself and your worlds, then I shall have no mercy!" Drakkon refused to hold back.
Overwhelmed, but the Sentais and the Rangers managed to put a really good fight against Lord Drakkon and the Bloodrunner. Impressed by them all, the threats slowly increased their usage of powers. The Sentais eventually also ended up using stronger form to compensate. The Rangers did the same as well.
"Let's protect your Earths like you have been doing for generations!" Both the Queens buffed the Sentais and the Rangers, then transform their clothes and jumped to combat.
Struggling to kill any of the Sentais or Rangers, Lord Drakkon and the Bloodrunner ended up going against the Queens of Keves and Agnus as well.
"Bullshit! Now there's Keves and Agnus!?" Rigna is frustrated.
At the same time, Bahamut, the Dragon King (having survived the destruction of the Night City), emerged from the rift.
Note: Bahamut, sometimes known by his epithetThe Dragon King, is among the most prominent summons in Final Fantasy. His signature attack,Megaflare, is a great breath of energy concentrated into a beam and fired to opposition, which deals(typically non-elemental)magic damage that ignores defense and evasion.
"Look! It's the Dragon King!" Queen Melia noticed Bahamut.
"Now! Help us, the Dragon King!" Queen Nia asked for help. "These Rangers could potentially be killed by those two monsters!"
"Use Megaflare!" A woman riding Bahamut.
That woman is actually Lina Inverse. She's doing the Gunbuster pose complete with one of the most badass arm fold possible. This came in the joy of the Sentais and the Rangers, and frustration of Rigna and Drakkon.
"Everyone, stands aside!" Queen Melia warned the Sentais and the Rangers. "Bahamut is charging up the Megaflare, and he's about to fire it at any moment!"
"Don't move, Drakkon! Don't move, Rigna!" Queen Nia distracted both threats.
"Actually, it's even better than Teraflare... or Exaflare, for that matter!" Lina told everyone. "Far better, in fact!"
"What?" Lucy asked Linda. "You meant far better, Miss Inverse?"
Everyone except Rigna and Drakkon ran away, while the latter two is confused.
"What the hell is this?" Drakkon doesn't know what Bahamut has in store.
"We call it..." Lina announced. "Xenoflare!"
"What!?" Rigna is confused.
The Sentais and the Rangers at this point are all very far away from Rigna and Drakkon, as for safety purposes. Then they all met the main Heisei Riders, Zero-One (Aruto Hiden), Saber (Touma Kamiyama) and Revi (Ikki Igarashi) and Vice. And then some.
"What's the matter?" Saber asked everyone.
"We've a fight with Lord Drakkon and Rigna the Bloodrunner, until Bahamut came here to do Megaflare." Zenkaiser explained. "They blackmailed is and tried to kill us."
"Bruh, I knew they would violently compromise you all!" Ex-Aid (Emu Hojo) knew it.
"Those dumbass want to mess up with Super Hero Time?" Revi asked.
"Actually, Bahamut is the one to handle this." Gokai Red (Captain Marvelous) responded. "That one has Megaflare."
"Megaflare? Nice, that Final Fantasy attack huh?" Ex-Aid recognized the ability.
"But she said Xenoflare!" AkaRed swooped in.
"Wait... what!?" Ex-Aid is shocked. "Xenoflare!? That version could destroy so much, and is able to fracture space and time!"
"An entire universe might be destabilized once Xenoflare hit the target!" Ex-Aid continued (not "continue"-ing the game, but rather, continue explaining)
"Then we're dealing with multiversal shenanigans." Red Ranger of the original Power Rangers admitted. "First, we ended up fighting our respective counterparts from another versions with that respective powers of ours. Then, Lord Drakkon returns and befriended a multiversal criminal. And now, Bahamut is going to destroy this Earth and more?"
"I've known the Warriors of Light ever since I arrived at Cornelia, just after the incident with Infinity Ultron." Zi-O told the Sentais.
"Here's the book." Zenkaiser then gave Saber the Super Hero Senki Wonder Ride Book.
Cross-trivia: Saber Super Hero Senkiis Saber's Zenkaizerbased form, accessed by using the Super Hero Senki Wonder Ride Book (Wonder Ride Book being the trinket)in the Seiken Swordriver (the driver). (insert that Wonder Ride Book to the right slot)
This form is exclusive toKamen Rider Saber Kikai Sentai Zenkaiger: Superhero Senki.
"Thanks." Saber takes the book and inserted it.
"Ohma, time to take note." Zi-O then subconsciously turned his Ziku-Driver into Ohma-Driver.
"I only have my own card and that K-Touch." Decade (Tsukasa Kadoya) then used K-Touch 21. "The latter has been used already, so I'll go for the latter."
"Finally, I get to use this peculiar Combo again." OOO (Eiji Hono) then inserts Taka, Imagin and Shocker Medals into OOO Driver.
"Dude, I got you the hybrid." Cross-Z (Ryuga Banjo) brought Build (Sento Kiryu) the Cross-ZBuild FullBottle.
"Thanks, Ryuga." Build inserted both Hazard Trigger in Max Hazard mode and Cross-ZBuild Can into his Build Driver.
"I'll take Evol." Cross-Z then inserts Muscle Galaxy FullBottle into his Build Driver.
"Here, the Zero-Two." Zero-One brought the Hiden Zero-Two Driver and the Zero-Two ProgriseKey to his Humagear-assistant Is. "You go 002, I do Realize." *activates Hiden Zero-One Driver and holds the Realizing Hopper ProgriseKey*
Is takes the Zero-Two units and activated it. "Yes."
"I just borrow my son's power, and we must do something to survive." Drive (Shinnosuke Tomari) inserted the Shift Special into the Shift Brace and engaged the Drive Driver. "Mr. Belt, let's go."
Fourze (Gentaro Kisaragi) was fumbling with the Fusionstates Astroswitches, and just managed to insert them correctly into Fourze Driver, alongside the Cosmic Switch. "Let's go, friends! It's space time!!!"
"Not just that." Wizard (Haruto Soma) inserts the Infinity Wizard Ring. He also has both the Finish Strike Wizard Ring and the Hope Ring on queue for transformation. "It's showtime."
"Go ahead." Ghost (Takeru Tenkuji) found the Tenka Touitsu Ghost Eyecon. "All life is on us." *inserts the Eyecon into his Ghost Driver* Specter (Makoto Fukami) did the same, with the Sin Specter Ghost Eyecon.
Kabuto (Soji Tendo) and Gatack (Arata Kagami) reached out for Hyper Zecters, Den-O (Ryotaro Nogami) takes DenKamen Sword and K-Taros, Zeronos (Yuto Sakurai) takes the red Zerono card with its red side,... The rest of thise Heisei Riders went with their finals.
"Look at Bahamut, around there, charging the Xenoflare." Ex-Aid pointed Bahamut. "At this point, it's almost fully charged."
"Just some more, and this world will rupture..." Kuuga (Yusuke Godai) commented. "So we go..."
The Riders went on with the transformation. Geiz, Woz and Tsukuyomi have to transform as well.
"Super Sentai and Power Rangers! Are you ready?" Woz shouted.
"Henshin!" The Riders transformed.
Meanwhile, Rigna and Drakkon is fighting each other about who should kill Bahamut and whether to do so.
"I don't know!" Drakkon strokes Rigna. "What if it explodes!?"
"You stupid minion!" Rigna then kicked Drakkon. "What's gonna happen when Bahamut fires us with that!?"
As both threats fight against each other, Lina Inverse is watching while Bahamut is charging the whole thing.
"Fight! Fight!" Lina cheered. "Can't wait to see your flare rewards!"
The beaten down twos still went out to beat up with killing intents.
"Fuck you! Naive commander!" Drakkon shouted.
"You imbecile!" Rigna responded back. "I'm gonna teach you a lesson!"
"Yeah, yeah, yeah, fight!" Lina shouted. "At the end, Bahamut will destroy your both!"
"Do something to destroy that Dragon King for once!" Drakkon is going crazy.
"You're not competent anymore!?" Rigna replied in anger. "Then fuck off!"
"I don't care!" Lina responded to both. "You're just monsters destroying multiverses!"
"Bahamut is almost ready." Lina noticed. "Just a few more moments..."
At that point, the Riders became: Kuuga Super Rising Ultimate; Hyper Kabuto and Hyper Gatack; Den-O Super Climax Form, wielding DenKamen Sword; Kiva DoGaBaKi; Decade Complete 21; W Extreme Gold; OOO Tamashii; Fourze Meteor Nadeshiko Fusionstates; Wizard Gold Infinity Dragon; Drive Type Special; Mach (Go Shijima) Chaser; Ghost Tenka Touitsu Damashii; Sin Specter; Ex-Aid Mighty Creator VRX (level VR); Cross-ZBuild Hazard-charged; Cross-ZEvol; Ohma Zi-O; GeizMajesty; WozGingaFinaly; Zero-One Realizing Hopper and Zero-Two; Saber Super Hero Senki; Ultimate Revice (Ultimate Revi and Ultimate Vice), and the rest in their respective final forms.
"Seek a way out!" The Riders shouted.
Aurora Curtain appeared and transported Sentais, Rangers, Riders, Lucy, both Queens and AkaRed.
By that time, The Xenoflare is fully charged.
"It's over, two monsters!" Lina then escaped.
"How dare you!!!" Drakkon is enraged.
"Shut the fuck up!" Rigna punched Drakkon.
Not waiting anymore, Bahamut fires Xenoflare, overwhelming both threats. The blast is powerful enough to crash the space and time, breaking both and left a colossal explosion.
"Fuck you-!!!" Rigna is consumed by the blast.
A massive, astronomically considerable chunk of that Earth is blown up, while much of the rest of it was fizzled into plasma-hot ball. The explosion is shown in space as a extremely bright flash that lasted as long as the blast persisted. It also left a gaping rift that's more than half as wide as the Earth is large.
In the World of Zi-O...
"Back. To. This. Kingdom." Ohma Zi-O is relieved.
The Sentais and the Rangers celebrated their survival.
"Good thing we escaped." Ex-Aid knows.
"Story chapter is over!" Den-O shouted, breaking the fourth wall in the process.
Few moments later, a mysterious image appeared.
"Found you, Zi-O!" That's Infinity Ultron!
"What the hell!?" The celebration is cut short.
"No..." Lucy is scared.
"Infinity Ultron and others!" Queen Melia recognized Infinity Ultron and friends.
"Damn it! We thought we'd have escaped!" Queen Nia is frustrated.
Infinity Ultron and friends emerged.
"Another Riders from the Worlds of Kamen Rider." Nekron chanted. "Rise."
"We meet again, the Demon King of Time!" Ultron-Sigma D recognized Zi-O.
"What have you done!?" Ohma Zi-O asked.
"We merely recovered and destroyed multiverses and its life, converting some of the latter into bidding." Ultron-Sigma D explained.
"You shall be erased from the existence itself." Archon announced. "Any questions?"
"Asmodeus of Super Hero Time." Nekron chanted. "Rise."
"What are you thinking?" Queen Melia asked.
Suddenly, Asmodeus and a massive army of Another Riders are summoned.
"This can't be!" Zenkaiser is shocked.
"Asmodeus is back!" Saber is angry. "Unbelievable!"
"I have returned!" Asmodeus rejoiced. "And this time, you must die!"
Another Riders is very damn vicious, from the look of it. Another Decade, Another 1s and Another Ohma Zi-O are even featured in multiples.
"You really have a death wish now." Infinity Ultron declared. "The bloodbath shall commence!"
"Go, Another Riders, go!!!" Asmodeus shouted.
"We must protect our history." AkaRed the called the Showa Riders, G4-X, the manga Kuuga, all those future Riders, Kamen Rider Ginga, the Kamen Sentai Go-Rider and Hikounin Sentai Akibaranger. The rift instantly ended up summoning the Showa Riders, Akibarangers, Go-Riders, Ginga, Shinobi (Rentaro Kagura), Hattari (Isamichi Konjo), Quiz (Mondo Douan), Kikai (Rento Makina), New Den-O (Kotaro Nogami), future Kiva (Masao Kurenai), future Ghost (Ayumu Tenkuji), Century (Ryunosuke and Hideo Momose), future Garren and Leangle (from year 2305), and Drive Type Next (Eiji Tomari).
