(The Hyperdimension Network Heroes charge at the Another Riders and Bat 10 becomes Humungosaur, and then he accesses his ultimate form.)

Bat 10 (U. Humungosaur): Ultimate Humungosaur!

(Then Bat 10 shoots some missiles which blast the Another Riders away. Then another Den-O charges at him.)

Diend: (pulls out a card) I don't think so, Another Den-O.

N. Diendriver: Attack Ride: Blast!

(Then Diend blasts Another Den-O with her shots, and pulls out another card.)

Diend: I'll end this at once!

N. Diendriver: Final Attack Ride: D-D-D-Diend!

(Then she shoots Another Den-O, who screams in pain before exploding.)

Diend: I should really help my brother more, especially after he got a girlfriend which is a complete yandere.

Eradicator: (comes in) Hey, are you gonna keep talking or what?

(Then they turn to Another Kiva and they blast him away. Kamen Rider Grease is seen fighting alongside Esdeath against Another Decade and Another Double.)

Grease: Okay, fake riders. Time to end this.

Esdeath: Yeah, me and my sweetheart will finish you fakers.

A. Decade: Try us.

Grease: With pleasure!

Driver: Scrap Finish!

(Grease uses his Machine Pack Shoulder to generate Variable Jelly in order to propel himself forward as he delivers a powerful kick coated in gold energy to the two Another Riders while Esdeath slashes them, and both explode.)

Esdeath: We did it, darling.

Grease: Not yet, my dominant ice queen, there's still more Another Riders.

Esdeath: (smirks) Let's kick their asses.

(They charge at Another OOO and Another Fourze. Timer punches Another Wizard, and blasts him to the wall.)

Timer: It's time for Samurai Style.

(He pulls out of another ridewatch.)

Timer: Powers of Kamen Rider Zi-O Gaim Armor, commence!

Wristdriver: Rider Time! Kamen Rider Zi-O! Armor Time! (Horns and traditional Japanese music) Soiya! Gaim~!

(Then he transforms into Ryujin the Samurai Dragon God, and charges at Another Gaim, kicks and punches him.)

Timer (Ryujin): Time for the big finish!

Wristdriver: Finish Time! Gaim! Squash Time Break!

(Then he slashes Another Gaim various times until he explodes.)

Timer (Ryujin): It's done.

(Invincible is seen fighting Another Drive.)

Invincible: Let's go!

(Then Invincible starts punching Another Ghost non-stop until he sends him crashing into the wall.)

Invincible: Is that all you've got?

(Then Invincible pierces through Another Ghost, killing him.)

Invincible: Let's rumble.

Woz: Let's finish this!

Bat 10 (U. Humungosaur): Is everyone humungously ready?

Heroes: Yeah!

Bat 10 (U. Humungosaur): Let's combine our powers.

Woz: Let's finish this!

(Then they jump high and prepare their attacks.)

Bat 10 (U. Humungosaur): Now!

(Then in a combined attack, the heroes easily finish almost all of the Another Riders. The last Another Rider remaining is Another Ex-Aid.)

B. Rouzer: Lightning Sonic!

(Then somebody kicks Another Ex-Aid, causing it to explode. Then it's revealed to be Marcell Henry, also known as Kamen Rider Blade.)

Invincible: Hey, Marcell. It's been a long time, huh?

Blade: Indeed, Mark. (to Ladybug) Our friend Cosmic Virgo said you would need some help.

Ladybug: Thanks.

(Then some girls come in, and Cat Noir gets on his fighting stance until Kamen Rider Cross-Z stops him.)

Cross-Z: I'm glad you came here, girls.

Ibara: You were right about one thing, Itsuka.

(Flashback)

(At the Union Spaceship, the Headmasters are seen discussing plans.)

W. Woman: Bruce's son. He's the source of the insurrection.

Ironwood: We must surpress this filth. Freewill leads to anarchy. It cannot be allowed to spread.

Superman: The people in our world also secretly whined, complained, sided with the Traitors, the Insurgency and other criminals. If they prefer chaos, I'll give it to them. Gotham and Bellwood. I'll flatten them, set an example. And then I'll make Bruce's son and his squad pay for interfering with our attempt to rule their earth.

(Meanwhile the Class 1-B girls overhead the conversation.)

Ibara: That was crazy, and it still is.

Pony: I know, right? Wiping out major cities? Invading worlds in other dimensions?

Kinoko: This is going too far.

Pony: There should be limits, even on us, especially on us.

Reiko: Have they actually gone nuts?

Setsuna: This is not what we signed for.

Yui: Izuku wasn't a criminal. We all know that.

(Back to present.)

Yui: They're planning to reduce Gotham and Bellwood to ashes, and then they'll come for you all.

Mega Man.EXE: Let them try.

(Back to the Union Spaceship, Ozpin is sitting on his throne until Slasher the Ant-Mantis Kaijin comes in.)

Slasher: Hello, Ozma.

(Ozpin tries to attack Slasher, but gets grabbed by him.)

Slasher: You think you can take over the world? I don't think so.

(Then Slasher chomps Ozpin's left arm, causing him to scream in pain.)

Slasher: Overlord Ohma Timer will erase humanity's existence. My buddies will come to help me to capture Timer himself. Say goodbye to your pitful life. Vilgax will break free any moment. He know your plan.

(Slasher leaves through a portal.)

Ozpin: I got to warn the others, this war between us and Hyperdimension Network Heroes cannot be finished.
