Telos took out an Ouroboros Stone, only for Laughs to literally wipe it out. The planet-machine kept pulling that out, but the Ouroboros Stone is constantly deleted by the dark matter of the abomination.
"Damn it! He keeps deleting the solution!" Travis vents out.
"Kill the Lost Numbers. You can do it." Laughs encouraged the copies to do the job.
"I knew it!" Telos facepalmed. "You would counter-"
"We gotta bring Alvis and that man!" Future Shulk told the mains. "Go bring both!"
"If we can't use the Ouroboros Stone, so be it!" Future Shulk shouted. "Bring N and our machine here!"
Charlotte took note and instantly reached for the Portal Device. It didn't work, much to the villainess' annoyance.
-*evil laughs* "I learned for my mistake that let that alien get away! You cannot summon anyone using that insane device anymore, because I sealed it while you rescued!"
"This leaves domes our only option, but..." Access heard it all.
"Well, he could send new copies to wherever we reach, so by the moment we summon, we risk drawing them in!" Telos reattaches the two Boost MarkIX Buckles into MarkIII. "Keep adapting, abomination."
Cue Laughs raging as Telos inserts the fused Buckle to the Raising Sword.
"All 20! Zero-Two! Xross! Giffard! Xross Giri!"
Some copies reluctantly listened, and prepared to the kill the Founders.
"Die, you fodders!" The copies simultaneously said with Telos and Access.
The latter two protected the Founders with slashed that quickly destroyed all the copies (even Red Death due to Zero-Two speed and Zi-O's and Kaiji's time abilities, plus the God of Creation powers bypassing reality straight to the targets), saving the Lost Numbers in the front.
"Thanks." Panacea thanked for the quick finish.
"Boss, we're still living!" Linka indirectly mocked the copies.
Future Shulk and Future Rex then finished off remaining copies nearby. "Good."
Telos parried a blast from Laughs, and took the exact moment to summon an Ouroboros Stone. This time...
"Enough, you monster!" Angelique went Hyper Clock Up, intercepting Laughs to give time for Telos to overclock the 'Stone.
"YOU!!! HOW ARE YOU EVEN!?" Laughs is diverted away from the 'Stone, ensuring Telos the time to infuse the power of the Trinity Processor altogether.
"Pneuma, Logos, Ontos, go!"/"プネウマ、ロゴス、ウーシア、行け!" Telos successfully overclocked the Ouroboros Stone.
"Let's go!!!" Matthew exclaimed. "Yeah!"
"Finally, we can recreate the first Interlink!" Travis gets excited.
"We will not deter!" Angelique then went back and kicked the Ouroboros Stone.
With holy-Gatack causing the 'Stone to slide, Travis got it and is ready to...
"Activate the Ouroboros!!!"
With Travis activating the Ouroboros Stone, the Sinners cheered "Ouroboros! Ouroboros! Ouroboros!" to the Founders, who are empowered by the wave from the boosted 'Stones, giving them the same power used to let them initiate the first Interlink; such Interlink can now be recreated, but more importantly, each members and co. is now as powerful as an modern Ouroboros.
As for Matthew and Na'el specifically... they now have dual Irises each: the Agnian one they were technically born with, and the Kevesi one partly awakened from their ancestry with the Ouroboros duo Noah and Mio, and partly from the loading of the power itself.
"Also now, even my machine... feel like a Blade I once lacked." Nikol noticed his machine reacting with power. "Good."
"Yeah!" And the Sinners proceeded to mop up the remaining copies.
With the Sinners and the Lost Numbers slaughtering the copies (and the summoning of copies never happened again), Laughs is frustrated at the team overcoming the adaptation and planning he did. Furthermore, Malal and Valda clashed the abomination again.
"Hyper Clock Over!"
And soon enough, nearly all the copies were destroyed. Only some are one member of original Dark Knights each, and they're all the only one left that's still willing to fight. These ends up proceeded to go for a stalemate against the Lost Numbers, forcing the Sinners to aid.
"This is for all realities!" Heathcliff bashed a Drowned.
"I'm Pyra-noid. I'm Glimmer!"/"ホムラから来ました。カギロイです!" Glimmer burns the Devastator alive.
"The passage of fate is ours, not yours!" Future Shulk and Future Rex jointly ambushed a Dawnbreaker.
"Hmph." Kronii smirked at Laughs. "Many of us are godlike. You're a god, so we're technically even. It's our will and teamwork that makes the good difference. You instead have your in-"
"SHUT UP!!!" Laughs had enough.
"No-" Shulk suddenly got a future vision - most likely caused by a surge of power messing with his sense, recreating his vision.
There, the copies explodes, burning the Founders and killing the Sinners. Then Laughs absorbed the lost life forces of the latter and then directed to the remaining ones to kill.
"Stay out! Everyone, stay out!" Future Shulk shouted.
The Founders leaped right back, while the Sinners, being mishmashed in terms of teamwork, is confused.
"Oh no!" Charlotte went Hyper Clock Up, and approached.
She pushed each Sinners very gently, knowing it would translate into an equivalent to a unpowered Rider Kick each time, giving the distance needed to save the Sinners.
"Hyper Clock Over!" And at the same time, the copies exploded. Because the Sinners were all knocked into distance, they were saved.
"Thanks me and Shulk later." Charlotte told the Sinners.
"Super Sentai! Xross Giri!"
"Take the powers of the Super Sentai!" Access gave the Sinner and the Final Knight all powers of Super Sentai.
The result normally would have gone out of control to to sheer power overwhelming each one, but instead they just untransformed and instead have glowing emblems of the first 46 series of Sentais swirling around each Sinner and co.
("I don't want to fight so much, but oh well...")
"Yeah. Because our Dante normally don't fight. He just prays for us not to die in our missions." Yi Sang clarified. "Anyways, all those powers together could've overwhelmed us to death there. You must have an extreme power control right now." *chuckles*
"Get ready for the end! Lost Numbers, go Interlink!" Telos pulls both levers and immediately slashed Laughs off. "Valda, power kick!"
"Command no toki! Lock on."
The four Riders gathered, and so did the Sinners and the Lost Numbers respectively.
"We unleash the power surge, we Interlink, so alright. Go!" Matthew bump his fists to each other, unleashing the power and stay the Interlinking.
Access inserts Kyomu into the Swordriver while the Super Hero Senki is accessed with Xross Saber, leading to...
"Eternal Xross! Cross fire! Subete o setsuzoku suru!" The Swordriver accepts Kyomu, allowing it to convince its power with the Haouken. This also further boost the powers of Kamen Rider and Super Sentai.
"Funny. Normally Kyomu wouldn't accept anything but the Haken Bladriver, huh." Access is amused at the effect. "Great, now I get both creation and destruction on my own!" *automatically gains the Dragonic Booster* "Even greater!" *scans the Almighty Wonder Ride Book with the 'Booster*
"1, 2, 3!"
"Hanabero! Reading! Almighty! Dragonic Almighty Spicy!"
Valda and Malal dissipated to empower the rest of the team with their powers. The Interlink complete, and tries to encompass the rest... except Full Armored Travis flying.
"I could just reset-" Laughs is then bombarded by Travis.
"Now!" Travis shouted.
Interlink succeeds, briefly absorbing the Sinners and the Final Knight, gaining their powers on top of Ouroboros (while the looks remain identical). Then they prepared for a coordinated punch to drive...
"Rider Kick!" The four Riders leaped and activated, initiating...
"Command Twin Hissatsu Geki!"
"Ginga Super Hero! Musou Shūreppa!"/"銀河スーパーヒーロー! 無双蹴烈破!"
"Rider Kick!"
The four Riders drop kick with all the powers they have, then driven by the Interlink lunch empowered by the power of all the first 46 series of every Sentai mechs ever plus our Sinner and Signal, all for multiversally enhanced taste of the power of all Kamen Rider and Super Sentai, straight to the abomination. And with all the Holo-girls and youths empowered by Valda and Malal all striking to the one Who Laughs at the same moment, for good measure.
"NOOOOOOOOOO!!!!!" Laughs is massively knocked out of the battlefield.
Everyone back to normal and untransformed back, and Gawr dissolved into water.
"Hoo! That takes care of the abomination of the week." Matthew comes down alongside the Lost Numbers.
"Thanks, miss... Atom?" Jack replied Valda.
"He's not going to come back to us anytime soon." Telos domed to bring Tracking Error. "We're free now. We can get back, all our things back to normal."
"You don't wanna fight? You wanna hide?" A fighter goading Tracking Error.
The team enters C Street, and caught wind of the argument.
"Hey! You have done yet?" Tracking Error noticed.
Then the fighter screamed at the notice, unsurprisingly seeing Telos and Malal as monsters, Valda and the Holo-girls as aliens, and the Final Knight as a dark knight.
"Luke Sullivan from Street Fighter, I see." Charlotte then explained everything that led to all this so far.
However, such explanation was absolutely complicated, and Luke quite literally were confused.
"What?! You have to listen!"
The team showed a presentation about what was happening and what everyone went through thus far, but Luke doesn't care and wants to fight.
"Luke! Knowing is half the battle!" Telos stalls Luke. "If you don't get the idea, you won't know how to survive!"
"Remember when two of your fellows became Power Rangers?" The villainess herself actually knows...
"Wait, you mean... these two?" Luke caught on.
"Ryu and Chun-Li."
"What?! Exactly them?"
"And they got into Reality Zero. Alongside some other fellows. You're a World Fighter, just like them."
This and explain what the Divine continuum is made of, one by one, helps Luke understand the situation everyone is in right now. It doesn't mean they're not aware of being watched, however.
"We're already being watched by the destructors serving for the Order, and they could ambush us any time." Angelique quietly reminded Luke of the surroundings. "You wouldn't know until they show up-"
"Tracking Error!!! YOU DARE ESCAPE US!!!" A furious Realitier spotted the team. "And you, other prisoners, and that villainess team too!!! YOU!!!"
"Fuck you! Your rank got my family... my love... my guests... all killed!" Angelique is enraged and canonically out-of-character, having suspected the Realitiers masterminded Laughs into the confrontation that took such lives. "You must be among those!!! WE'LL KILL YOU!!!"
Angelique prepared the Gatack Zecter and is about to attach, but is stopped by her spoiler-sister Charlotte.
"It's dangerous! You cannot just beat them up alone!" Charlotte warned.
"How did you guess that we're working with an alternative version of one of our founders?" The Realitier gets even more suspicious. "Great. EVEN MORE REASONS TO STOP YOU ALL!!! YOU TOO, FORMER EXECUTORS AND THOSE GIRLS THERE!"
"We forgot- Where's Mar-Vell?" Tracking Error panicked.
"I got him while you were escaping from the Mobius Chair I know you used!" The Realitier holds a bloodied corpse of 616!Mar-Vell. "He's dead again. Just like in canon. But this fanon time, I killed him."
The entire team gasped in horror, and Luke even more so: he's so terrified, he immediately covered his eyes.
"This is too much damage to a fighter! Overkill!"
The Realitier simply laughed. "How about... revive Geiz?"
Another Geiz Ridewatch is on the hand of the crazed executor, ready to be used on the dead Captain Marvel.
"We thereby declare: as your punishment, the Mar-Vell of Earth-616 spends his afterlife as Kamen Rider Geiz!" The Realitier inserts the Anotherwatch into the corpse.
"Geiz!" And the corpse morphed back to life, into a monster rendition of Kamen Rider Geiz with visor as sharp as that of Geiz Revive but with human-like, horrifying eyes in. The armor is scuffed, distorted and dinted and dented, yet still has uncanny resemblance of Geiz.
The Another Rider roared at the team.
Telos gave a 5-U-93-R pill to Luke. "Take it. You'll become a super-powered fighter!"
"Why don't you just fight that monster instead!" Like complained.
Telos forced the pill into Luke's mouth. "We have to get out of the way for now!"
Luke accidentally ingests the pill and is about to become superhuman. Telos grabs a Diendriver, attached the Attack Ride: Invisible card, and...
"AttackRide: Invisible!" *trigger!*
The team becomes invisible and then ran away, leaving Luke by himself. Another Geiz charged ahead, but the fighter... semi-surprisingly blocked.
"Wait... I'm a superhuman now?"
Another Geiz then tried to beat down Luke, which would've certainly killed a normal human. But Luke can safely withstanding with no more than mere humanly bruise, proving the pill works.
"Aha! That pill is... amazing!" Luke sprang back and stanced to his own. "Well, look like I'm even!"
Another Geiz stumbled, and is shocked to see Luke survive and in fighting shape. Using his moves and experience as a World Fighter, having fought some fellow combatants from his Earth already, Luke manage to keep up against the monstrous rendition of "El Salvatore".
Not long afterwards, Another Geiz exhausted options, and has to resort to "Another Time Burst", kicking Luke with glowing sole (eerily reminiscent of Geiz's own finisher kicks). This doesn't prove fatal at all, as the fighter is simply bruised, and barely drew blood.
Luke then finished off the Another Rider in vein of his home game, defeating the monstrosity with his own fighting boosted by 5-U-93-R. However, this is noticed by the raging Realitier.
"5-U-93-R?! I CAN'T FUCKING BELIEVE IT!" The Realitier ragequitted. "I quit this world! Luke Sullivan used 5-U-93-R to help the villainess and co. beat my Geiz!"
The Realitier is decapitated by Charlotte using Kinetic Blade infused with dark magic. Another Geiz, meanwhile, struggled to get back up and restore himself.
