=======>Meanwhile, at Gotham Warehouse<=======

When Vandel Savage was running from another DaiKaiju since he killed all his men and servants, it was Another Decadus who was chasing after him. 

Vandel: *scared* P-Please, I can give you anything: money, women, power, anything you want.

A. Decadus: *glare* You humans always think you can give me money, power, or others. You're sicking me & disgust, you called yourself human. I called them a ruthless apes who thinks they're smarter than humans, and guess what.

Then he grabbed his collar ruthly as he glares at him.

A. Decadus: *snarls* I'm gonna enjoy killing every single humans in my path, and I will destroy all of you pesky so-called heroes & villains for good.

He slammed his head to the wall as he ended him up by breaking his whole tire face and breaking his skull, finally Vandel died as Another Decadus threw his dead body to the ground as he smashed his skull apart by spilling his blood over the ground.

A. Decadus: As long as I will destroy this world of Injustice, this world will be my domain and I'll never give up fighting against Decadus, Primordial and Divine. Timejacker will live forever.

=======>Meanwhile with Team Destroyers<=======

Ethan, Ty and Decadus are travelling through Metropolis where all people are frightened of Superman and the Regimes, Decadus whistled.

Decadus: *whistle* He sure is evil.

Ty: Who knew Superman can be evil sometimes.

Ethan: Although, him & his Regimes needs to be destroyed so the world will saved.

Ty: I wonder who will be the new Insurgency?

Decadus: If all of Batman's team are dead, I wonder who's gonna be the new Insurgency?

They kept on walking through the streets, suddenly a group of Yummies surrounded them as they're ready to attack.

Ethan: I've never seen these Yummies before.

Ty: What type of Yummies are they?

Decadus: Let me see you Kaiju-Dex.

He hands him a Kaiju-Dex as he scanned the Yummies, then it reveals the new type of Yummies on the device.

Decadus: They're called Hollow Yummies, these Yummies are like Egyptian Type, the more their get and the more they're stronger than regular Yummies. Hollow Yummies are toughter than humans, inhumans, metahumans or half-humans, they only fight against Kamen Riders, Super Sentai, Alien Heroes or Earth's Monsters to fight them. They only served Kamen Rider Shocker.

Ethan: *shocked* Shocker!

Ty: *shocked* I thought he-

Decadus: He's already dead, these Yummies needs to be taken out.

Ethan: Let's do this.

They pulled out their drivers and insert their cards, while Decadus pulls out his new upgrade form as he inserted it in his WristDriver.

Ethan/ Ty/ Decadus: Henshin/ Dai-Henshin!

Announcer: KAMEN RIDE. PRIMORDIAL!/ DIVINE!/ DAIKAIJU RIDE. DEDACUS!

Both Ethan and Ty tranforms into Kamen Rider Primordial and Divine, as for Decadus turned into his new upgrade form.

Primordial: I am the King of Riders & Kaijus, no one cannot stand against my ultimate might! KAMEN RIDER PRIMORDIAL!

Divine: I'm just a Treasure-Seeking Rider who seeks magnificent treasures! KAMEN RIDER DIVINE!

Dedacus:To Connect everything, to destroy everything. Decadus!

The Hollow Yummies growls as they started charging towards them to battle, all three heroes engage their battle stance as they charging towards the Yummies. Primordial pulls out his Rider Card as he insert it inside his driver and he faces back at both Divine & Decadus.

Primordial: Let's celebrate for speed.

They were pulled out of their cards as they saw another kaiju who appears to be a female dragonbat who resembles of Kiva-la who is slashing all of Yummies.

Decadus' eyes widened as his stared at her beautiful face and her armory while his heart beating fast.

Decadus: *thoughts* She's so beautiful.

Then a female dragonbat slashes all of Yummies as she defeated them all, then she grabbed the Yummy by the throat and she slashed them as they exploded. Finally, someone destroyed the other Yummies as they turned around and Decadus' saw a different Dicode, and it was A.R. Dicode.

Dicode: *smiles* Let's get rid of these Yummies.

He inserted the card inside of Diendriver as he pointed at them.

Announcer: ATTACK RIDE. BLAST!

He blasted all of Hollow Yummies as they exploded, he blasted another Yummies and the he saw Decadus' appearance.

Dicode: *eyes widened* Decadus!

Decadus: *confused* Huh?

Then Kivaia finishes the last Yummies as she sees Decadus as well, her eyes widened as she saw Decadus.

Kivaia: *gasped* Decadus!

Both Primordial and Divine looked at them at the same time, and they facing back at Decadus as they reverted back to normal state.

Ethan/ Ty: *confused* Huh?

Decadus: *confused* Excuse me, Dicode is that you? I though you died when you were part of the DarKaiju Legions?

Dicode: *confused* DarKaiju what?

Decadus: And you lady, who did you know my name?

Kivia: You're our leader, and you're hero again.

Decadus: I'm sorry, there must be a mistake here. I'm not this world Decadus. 

A. R. Dicode: What do you mean?

Then Ethan walked towards them.

Ethan: I will explain his history to you.

Ethan: No, Ty is my future son from the future when my future self died from Kamen Rider Shocker.

A.R. Dicode: Wait, as in 'the' Kamen Rider Shocker!

Ethan: *curious* You guys know him?!

Ty: Does he look like Dark version of OOOs?

A.R. Dicode: No, he's the worst. While me and Kivia battling him, our Decadus died from him.

Ethan: Then who is Kamen Rider Shocker anyway?

Kivia: His is from our world when Decadus became evil.

Ethan/ Decadus/ Ty: *confused* Evil?

Ty: Like how?

A.R. Dicode: When Decadus' friends: Andy Ross, Kabutron, Iron Jawz, Aerosaur, Hyo, Hydroius and Armorok are defeated by Team RWBY, JNR and the other Huntsmen who finally defeated them.

Ethan: Then what happened?

Kivia: Yang and Blake reset time on Kabutron's wrist Zector as they reset the whole time back as Yang and Blake convince Ruby and her friends to find Andy to ambush him from turning himself into Kiva. 

Ty: I'm guessing they defeated him and murdered Kiva.

A.R. Dicode: *nodded* Precisely. 

Decadus: Then why is your Decadus became evil?

A.R. Dicode: Our Decadus felt sadness that he failed his friends, then he took the dark path and turning himself into evil version and named himself known as-

Kivia: Dark Decadus.

Ethan: Dark Decadus, that's new.

Ty: What happened to Team RWBY?

A.R. Dicode: Ever since a mysterious reset time in Remnant, we can't team RWBY or JNR anywhere. But, I summoned Kivat the 3rd and Kivat the 4th to find them. 

Kivia: But, Dr. Watts is still alive.

Decadus: *curious* Alive, how?

A.R. Dicode: He's working with  this villain named Kilgore in the world of DC Universe.

Decadus: What the hell!

Ethan: Who the fuck comes up with that bullshit?

Ty: *sighed* You can blame WB Studios.

A.R. Dicode: But, In Justice League's Universe. They're not the only ones, me & Kivia know who lives in that Universe.

They got curious who lives in Dc Universe, and they faced back at them.

Ethan: Who?

Kivia/ Dicode:...............................DarKaiju Legions.

They gasped as they knew their name ever since the last Omniverse War of DaiKaiju-Verse & Megaforce-Verse. 

Ethan: DarKaiju Legions, you mean the Evil Kaijus who wants to take over the world.

Kivia: *nodded* Yes, how did you know them?

Decadus: Me and the other Heisei DaiKaiju Defenders fought against them back then, but some of our friends died in War.

Kivia: *gasped* Oh dear.

A.R. Dicode: They're all dead!

Decadus: Yep, all dead because of Chifuyu Orimura. They all sacrificed themselves for protecting us, Kaiju Gods rest their souls.

Ethan: I wonder how Dark Decadus will meet A.R. DarKaiju Legions?

A.R. Dicode: Idk, if both A.R. Remnant or Dc Universe has their monsters that are created. Their revenge will come for them.

Kivia: While that's out of the way, you two humans are the 4th Reiwa DaiKaiju Heroes.

Ethan: Yes, but right now, we are here to defeat Another Decadus the Timejacker Kaiju.

A.R. Dicode: *stern* Timejacker, we should've known he will come here.

Decadus: We might as well defeat all of Regimes first.

Kivia: But first, we must find shelter. We'll led the way, we had a bunker to keep ourselves saftey.

They began to follow them to their safe bunker so no Regimes will find them, then Another Decadus was watching them as he chuckled and he walked away. But, a certain cyborg was watching them from the skies.

Gigan: Hmm, A.R. Decadus and DarKaiju Legions. The crossover event between RWBY & Justice League has begun, not as long as we help them first..........right, my lord.

Then a certain Xillian Kaiju floated towards him as he revealed himself as the skeletal-like dragonoid with two heads on his shoulders with red eyes and it was........................
