(In a mall located on New Orleans, the parallel Takeshi Koga and Masamune Moriyama are seen shopping.)

Koga: I hope Ryo doesn't mind getting these for him.

Moriyama: I'm sure he doesn't mind, we bought him this book.

(They buy a book of mythical monsters from the beginning.)

Koga: I wonder what this book is about...

Moriyama: Probably about myths and legends, although I never saw that book before. Let me see it.

(As he opens the book, suddenly golden particles pop out of the book, and the world stops. Their eyes widen, and then they see all kaiju heroes and superheroes.)

(And then they see the heroes joining forces against the evil threats: the leader of Darkaiju Conquerors, Kaiser Virgolial and the leader of Kaotic Avengers, Eternal Dormammu.)

K. Virgolial: HAHAHAHAHAHAHAHAHAHAHA!

E. Dormammu: MUHAHAHAHAHAHAHAHAHAHAHAHA!

(Then the golden particles return to the book, and the world returns to normal.)

Koga: What was that?

Moriyama: Zane, Ben and Grimlock were there. But who were those guys with Godzilla?

Koga: I think we're not alone in this world. There are more universal heroes out there watching over against those two evil leaders.

Moriyama: But our friends are still out there. Who were those blue kaijus and that magenta creature who's got some of Kamen Rider Decade's features?

????: Your doom.

(Then they gasp and turn to see Bemstar who is terrorizing people.)

Bemstar: (glares) Our boss wants us to find any of the heroes. Now I found you, time to die.

Koga: Not so fast. Henshin!

Moriyama: Shodophone! Ippitsu Shojo!

(Then they transform into Kamen Rider Nigo and Shinken Red.)

Shinken Red: Shinken Red! Moriyama Masamune!

Bemstar: You idiots! Do you know who you're messing with?

(Suddenly a batarang hits one of Bemstar's eyes.)

Bemstar: Argh! My eye! AAAAARGH! ALRIGHT, WHOEVER DID THIS. SHOW YOURSELF!

????: You forgot to say "please".

????: Babs, should I remind you that we're dealing with a villain?

Bemstar: JUST SHOW YOURSELVES ALREADY, YOU SIMPLETONS!

????: As you insist...

(Then they look up to see a girl wearing a bat costume and a masked woman wielding a magic sword. They're none other than Batgirl and Katana.)

Batgirl: (smirks cockily) Did anyone tell you that no murdering innocent people who know our Cartoon Network friends are here?

Katana: Yeah, that samurai boy surely likes swords. That's totally cool.

(Shinken Red blushes at Katana's comment and Kamen Rider Nigo looks at Batgirl with a shiny smile.)

Bemstar: (growls) Who are you bozos?

Batgirl: I am Batman's best sidekick. (poses) Batgirl! (smiles) Boys like that.

Nigo: (dumbfolded) Do they now?

Bemstar: What the hell are you? A female Jaune Arc?

Batgirl: No idea, and language.

Bemstar: English.

Katana: And I am Katana, I purge all evil souls with my sword.

Bemstar: (glares) More deadbeats. Come on and fight me like puny humans you are!

Batgirl: (smirks) Okay then.

(Then the four jump up to fight him. Batgirl throws her batarangs at Bemstar, who absorbs them, and Katana cuts off one of his wings. Enraged, the kaiju tries to hit them with his Bemstar Beam, but the heroes dodge out of the way.)

Bemstar: (angry) HOLD STILL SO I CAN GET BACK AT YOU FOR CUTTING OFF MY PRECIOUS WING!

Batgirl: (smirks cockily) Well, you didn't give my batarangs back, so...

Katana: (smirks cockily) And besides, you can't even hurt a fly.

Bemstar: (stern) You. Are. About. To make me... angry!

Batgirl: (more cocky) I bet you can't even fly properly, you know why?

Bemstar: (stern) Why?

Batgirl: (smirks) Because you're fatter than a sumo fighter!

(Bemstar growls and tries to tail-whip the heroes, who dodge his attack.)

Bemstar: (angry) THAT'S IT! I'M GETTING TIRED OF THIS NONSENSE! YOU WILL DIE! ALL OF YOU! YOU HEAR ME?

(Then Bemstar tail-whips again, but Katana cuts off his tail. Even more enraged, he uses his powerful attack.)

Bemstar: ENERGY BEAM!

(Bemstar shoots a beam from his beak, and blasts the four away, and they crash into a wall.)

Nigo: Damn it...

Shinken Red: We can't be defeated like this.

(Bemstar approaches them, and prepares to finish them.)

????: HEY!

(They turn to see a boy walking in front of them.)

????: Leave them alone, Member of Chaos Avengers!

Nigo/Shinken Red: (in mind) Chaos Avengers?

Bemstar: (curious) Who are you, or how do you know I'm a member of the Chaos Avengers?

????: Easy, I read about you and your allies. You guys are a threat to humanity. You won't destroy our planet and our universe!

Bemstar: (glares) You don't have any powers. You're just a human.

????: No, but I have... THIS!

(Then a giant robot lands, and Bemstar's eyes widen.)

Bemstar: Who are you anyway?

????: I am Kyle Jackson!

(Kyle them jumps inside his mecha, and it starts becoming operational, much for everyone's shock.)

RX-93: And I am the pilot of RX-93 Gundam!

Bemstar: (eyes widen) That's impossible!

RX-93: Not anymore, and you're my opponent!

Bemstar: (growls) YOU'LL NEVER DEFEAT ME!

(RX-93 charges at Bemstar and punches his snout. Then he pulls his horn and throws him into the wall. He blasts the kaiju away with his 60mm Vulcan Gun. Bemstar charges at RX-93, only for the latter to throw him outside the mall. The other two heroes carry Batgirl and Katana while RX-93 is seen still fighting Bemstar.)

Bemstar: (angry) CURSE THOSE TWO SUPERHERO GIRLS! IF THEY HADN'T DONE THIS TO MY POOR EYE, WING AND TAIL, I WOULDN'T BE SO EASILY OUTSMARTED!

RX-93: (smirks) What? You asked for it.

Bemstar: (angry) I'LL KILL YOU! BEMSTAR BEAM!

(Bemstar shoots his beam, but RX-93 uses its shield to defend himself.)

Bemstar: (glares) You will never defeat me, Gundam Pilot! You will never be like Amuro Ray!

RX-93: Oh yeah? Let's see you handle THIS!

(RX-93 fires his Hyper Bazooka, destroying Bemstar with a single shot.)

Bemstar: NOOOOO! CURSE YOU, KYLE JACKSOOOOOOON!

(Then Bemstar finally explodes, and RX-93 flies away, leaving the two other heroes to watch.)

Nigo: Well, we got saved by a Gundam.

Shinken Red: Yeah, let's get back home. Ryo must be worried about us.

(Then they go to their vehicle and buckle Batgirl and Katana before driving back home.)
