Every citizens are in their handcuffed that the Justice League (Young Justice), Suicide Squad and Legion of Superheroes are together to make sure they won't escaped. As for Zack Synder, he got his co-workers ready for his next scene.

Zack: *devious smile* Yes, this is a perfect scene for those kaijus died. Roll the cameras. 

They viewed the cameras & other equipment, as for the Heisei DaiKaijus are in their cage. Below them there was a boiling lava underneath them, they looked at each other as Pacha sighed.

Vigo: Yeah, but as long as we got new friends here.

Virgoro: *nodded* Indeed. 

Tyler: And now we just got here, but caught by these former superheroes. 

Damien: No wonder why we are all here together. 

Armorok: Where the hell is Decadus anyway?

Aerosaur: *nodded* Yeah, he wasn't here since the last time.

Andrew: Who's Decadus?

T. Virgo: Decadus is a 10th Heisei DaiKaiju Hero, like the rest of us.

Andrew: Like the Heisei Riders.

Then Demonik was inside of the jar as he spoke to them.

Demonik: *muffled* And Who's Shin Virgo?

Virgo Jr: No idea, I didn't know Dad can be Shin in Shin-Verse.

DaiKaijus: *confused* Shin-Verse?

Then Supergirl banged the cage to get their attention.

Supergirl: *stern* Quiet, my cousin is gonna make some announcements.

Then a holographic screen shows Regime Superman, then Zack tells the cameramen to view him. 

R. Superman: Citizens of Briarwood, I know that we DC Superheroes make our career better. But, even though....that we have had it with this Kaiju vigilant work. Being vigilant is against the law that all heroes must earn the rights to reveal themselves, true heroes like us to earn our rights of heroism.

While Regime Superman was still talking, a Dimensional Gap opened as everyone turns around as they smiled in joy and they all walked through it. Jiro and the other human allies smiled in joy they've escaped, Then it was Decadus alongside another Heisei Kaiju Leader, the 20th Heisei DaiKaiju Leader: Timerdon. They both are behind Supergirl, as they faced each other as they nodded and knocked her out real quick. Finally, they head multiple footsteps as they turned around and saw Virgo & Godzilla's teammates.

Virgo: Okay guys, let's create our own scene of this movie.

They are ready to set up the cameras for their new movie, Superman nodded.

Kabuto (Jiro): WE ARE......................

Then it views all of human allies & DaiKaiju heroes all together to fight for freedom, justice, love, peace and balance. They got into their battle stances to fight.

Everyone: DAIKAIJU HEROES!

The explosions from behind make them more heroism in their battle stance, Regime Superman pressed the button to summon all of his Regime soldiers to fight against them. All of Regime Soldiers are here to fight against all of 20 Heisei DaiKaiju-Verse Heroes together in their battle, but a certain person came to battle as well and it was Kamen Rider Primordial who came into battle as well.

Primordial: *smiles* Mind if I join this battle.

Virgo: *eyes widened* That's him!

Godzilla: *shock* The Reiwa Hero!

As for Decadus, he sees Kamen Rider Primordial who made his appearance.

Decadus: *thoughts* Hmm, so this is a kid that Thunderbolt talked about. I thought he was joking, there really is a Reiwa hero who came from the future.....*smirking* I don't mind visiting him someday.

Kabuto (Jiro): Hey! Who or what are you?

Primordial: *smirking* My name is Ethan Fredrick and also..........I'm just a Passing through Kamen Rider who travels Space & Time, remember that.

He pulls out his K-touch, and press all eras of both DaiKaiju-Verse & Rider-Verse.
