(In Paris, the Atlesian Soldiers, the Devil Soldiers, Winter, Ace Operatives and Rias's Peerage are seen making citizens their slaves while killing some of them.)

Winter: Keep moving, people. Paris will be destroyed and become our fortress.

Rias: (smirks) After that, you'll become my brother's servants, your families will be separated and no...

(Suddenly they got blasted away, and the citizens turn to see the Hyperdimension Network Heroes as they start cheering for them. Winter growls as both Ace Operatives and Rias' Peerage get in their battle stances.)

Winter: YOU WILL NEVER STOP UNION, ALIEN DINO THUNDER FORCE!

ZO: Look, Ice Bitch, we're not Alien Dino Thunder Force. We're Hyperdimension Network Heroes and the Autobots, we are from a different Omniverse, and we're here to save people from fake heroes.

Rachel: This time you're history!

Wolverine: Let's go, bub.

W: Now, count up your sins.

Jack: Autobots, roll out!

(The heroes and the villains charge at each other and collide their powers and weapons. Kamen Rider Double kicks Winter, grabs her leg and throws her to the building. Mega Man.EXE turns to the devil soldiers.)

Mega Man.EXE: Time to extinguish those devils.

(Mega Man.EXE, uses his sword and slashes them in half. Meanwhile Winter glares at Kamen Rider Double.)

W: Come on.

(Winter charges at Kamen Rider Double, only to be kicked into the wall.)

W: Well Winter, your original self isn't even a little bitch.

(Rachel and Wolverine are seen fighting Kiba and Xenovia. Wolverine's claws keep clashing with Kiba's swords.)

Wolverine: (growls) Damn, he's good.

Rachel: Time to show them the power of the Phoenix Force!

(Then Rachel uses the Phoenix Force and burns both Kiba and Xenovia alive.)

Rachel: Yes, I did it.

Wolverine: Your mom wasn't so arrogant with her powers.

Rachel: You're just envious.

Wolverine: I guess you took the arrogance after your father.

Rachel: (glares) Let me guess, your father said that.

Wolverine: (smirks) Yep.

Rachel: (glares) I hate you.

(Gutsman.EXE and Optimus Prime are seen fighting against the Ace Operatives. Gutsman.EXE breaks their backs and Optimus Prime pulverizes them.)

Gutsman.EXE: Nobody, I mean, Nobody messes with this town.

O. Prime: They will never be true heroes. True heroes fight for freedom. Freedom is the right of all sentient beings!

(Ultraman Powered and Cadmus Clone Nightwing are seen pounding and blasting Rias' Peerage and Akeno glares at them.)

Akeno: You will die, and we're gonna rule this world.

????: Don't bet on it, Akeno!

(Then two Kamen Riders kick her, and then Timer comes with them.)

Gutsman.EXE: Who are you?

????: My name is Ryuga Katsuragi, this is my girlfriend Itsuka Kendo. And...

Timer: I am Timer the Time Mechanoid Kaiju, and ally of Kamen Rider Zi-O.

Rachel: And what brings you here?

Timer: I'm looking for Gamer the Mechanoid Player-Bot, ally of Kamen Rider Ex-Aid.

O. Prime: He must be at DaiKaiju Knights Omniverse. We'll help bring you in there as soon as we finish this fight.

(Winter and Rias' Peerage are seen glaring at them.)

Winter: (angry) IT'S TIME TO PUT THEM ALL IN THEIR PLACE, AND THIS INCLUDES THE TRAITOR ITSUKA!

Koneko: (to Rias) Let me handle them.

Rias: (stern) Go ahead, make them bleed!

(Koneko nods and walks towards them as Timer walks in front of them.)

ZO: Are you crazy? She's gonna kill you.

Timer: Don't worry, I got this.

(Then Timer pulls out a ridewatch and presses its button.)

Timer: (smirks) Meet the powers of Kamen Rider Zi-O, Fourze Armor. Commence!

Announcer: Armor Time! 3, 2, 1! Fourze!

(Then he changes to AstroRaptor the Astronaut Raptor Kaiju)

Timer/AstroRaptor: Come on, kitty cat. I'll send you straight into space.

(Koneko charges at Timer, who punches her repeatedly and grabs her through Rias' Peerage.)

Timer/AstroRaptor: Let's get this started.

(Then he presses his wrist driver.)

Announcer: Finish Time! Fourze! Limit Time Break!

(Winter, Rias and Issei get out of the way as Timer hits the rest of Rias' Peerage and they explode.)

Winter: Rias, we need to retreat. Those bastards will keep coming at us.

Rias: (nods) Right. (to Issei) Deal with those bastards.

Issei: Yes, buchou.

(They run back to the ship while Issei turns to the heroes.)

Issei: (smirks) Let's see what you're made of, weaklings.

Itsuka: Now, shall we begin the experiment?

(Itsuka pulls out two fullbottles and places them on her Build Driver.)

Announcer: Rabbit! Tank! Best Match!

(Then Ryuga makes his driver appear on his waist while Itsuka cranks up her driver's lever.)

Announcer: Are you ready?

Ryuga/Itsuka: Henshin!

(Then Ryuga becomes Kamen Rider Kuuga while Itsuka becomes Kamen Rider Build.)

Announcer: Hagane no Moonsault! RabbitTank! Yeah!

Kuuga: Let's do it.

????: I hope you don't mind us helping you, Issei.

(Then Class 1-A are seen along with Sakura and Sasuke.)

Sasuke: Time to show those losers what happens when they mess with us.

(They get in their battle stances as the screen fades out.)
