(The heroes are seen going towards a base.)

Lincoln: This must be the base.

Rarity: What should we do, darling?

Tokuro: Isn't that obvious? We must get inside the base and fight those bastards.

Zane: And this includes the Union Headmasters: Ozpin, Sirzechs, Azazel, Nezu, Hanzo and Chifuyu.

Goten: Trunks, are you thinking the same as I am?

Trunks: Of course, Goten.

Vegeta: Is that actually necessary? Most of them are not worthy of your combined powers.

Gohan: There are two energies I feel, and I can assure you that they're pretty strong.

Goku: It must be Silver Blood and Kamen Rider Nightmare.

Vegeta: If that's the case, we don't have any other choice.

Trunks: Alright, Goten.

Goten/Trunks: FUUUUUUUUUSION! HA!

K. R.: Henshin!

N. Decadriver: Kamen Ride: Decade!

N. Diendriver: Kamen Ride: Diend!

ForceRiser: Forcerise! Rising Hopper! Breakdown! A jump to the sky turns to a Rider Kick! Breakdown!

S. Driver: Soiya! Orange Arms! Hanamichi on stage!

R. Driver: Buddy Up! Ohing! Shoning! Rolling! Going! Kamen Rider! Revi! Vice! Revice!

G. Driver: Kaigan! Ore! Let's go! Kakugo! Go Go Go! Ghost! Go! Go! Go! Go!

Isaac/Izuku/Izumi: Select! Crystal!

Crystal: Overlap! The Three Souls!

Isaac/Izuku/Izumi: Enshrined by Reality! Immortal Truth!

Announcer: Ultraman Gruebe!

(Then the heroes complete their transformation as Goten and Trunks become Gotenks.)

Gotenks: Let's go for it.

(Inside the base, the villains and the Union Headmasters, except for Ozpin and Gabriel T. Rorke, are seen discussing plans to take down the heroes.)

Nezu: They have gone too far this time.

Wesker: Your students proved to be weak. You remember what Raven Branwen told Ozpin before leaving for her tribe.

Sirzechs: Are you saying that those people are stronger than my sister?

D. Bubble: That's right. The strong live, the weak die.

Vicky: The Bubble has a point. What happened to the supposedly best was just a proof of their weaknesses.

(Suddenly they hear an explosion in the door, and then the heroes come in.)

Chifuyu: Bastards!

Nightmare: So you're Lincoln.

Decade: Yes, and I'm ready to take you down.

(Goku and Vegeta transform into Super Saiyan 4 while Bardock and Gotenks become Super Saiyan 3.)

Saiyans: So are we!

Diend: Prepare yourselves!

(Kamen Rider Diend pulls out some cards and inserts them in his Neo Diendriver)

N. Diendriver: Kamen Ride: Zanki! Kamen Ride: Danki! Kamen Ride: Sabaki!

(Then three Kamen Riders are summoned.)

Diend: It's showtime!

(Then Kamen Rider Decade, Goku and Bardock fight Kamen Rider Knightmare while Kamen Rider Diend, his summoned riders, Vegeta and King Vegeta deal with Silver Blood and Gotenks faces Albert Wesker.)

Z. Zero-One: Let's go!

Femme: Alright!

Velvet: For freedom!

(The rest of the heroes fight the rest of the villains. Meanwhile, Kamen Rider Decade hits Kamen Rider Nightmare with a knee strike, and then he dodges his slash attack and kicks him in the chest before grabbing him and kneeling his face. In retaliation, Nightmare slashes Decade and kicks Goku. As both get up, Decade pulls out another card.)

Decade: Henshin!

N. Decadriver: Kamen Ride: Double!

Decade: (pulls out another card) Time to beat you!

N. Decadriver: Form Ride: Double! FangJoker! (Heavy metal guitar riffs to orchestral hit)

(Then Kamen Rider Nightmare tries to slash Kamen Rider Decade, but Lincoln swiftly dodges his attacks and slashes him four times with his Shoulder Saber, and then the three prepares to finish him.)

N. Decadriver: Final Attack Ride: D-D-Double!

Goku: Ka-Me-Ha-Me...

(Bardock charges up am energy blast too.)

Goku: HAAAAAAAAAA!

(Then Goku and Bardock shoot their energy blasts while Kamen Rider Decade hits Kamen Rider Nightmare with a Rider Kick, and the combined attack destroys him as Kamen Rider Decade returns to his original form.)

(Meanwhile, Vegeta punches Silver Blood, who tries to hit back, but the saiyan easily blocks it. Silver Blood tries to slash him, but King Vegeta breaks his sword and blasts him away with a ki blast.)

Vegeta: Hmph. Pathetic.

(Then the three summoned Riders hit Silver Blood, making him fall. Enraged, Silver Blood goes on a rampage, trying to attack the heroes, and then he sets his sights towards Diend, who pulls out a card and inserts it on his Neo Diendriver.)

N. Diendriver: Attack Ride: Barrier!

(The barrier shields Diend as he shoots Silver Blood three times. Even more enraged, Silver Blood unleashes a blast which barely harms the heroes as they survive. Then King Vegeta kicks Silver Blood, slams him down and punches his face. Silver Blood punches him back, but King Vegeta punches him twice, and then they have a brief clash before King Vegeta blasts him away.)

K. Vegeta: NOW!

(Vegeta charges up an energy blast while Kamen Rider Diend inserts the Final Attack Ride card.)

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

Vegeta: FINAL FLASH!

(Then the combined shots hit Silver Blood, finishing him off.)

(Cut to Gotenks, he charges at Albert Wesker and knees his face before being grabbed by him, and then he breaks free from his hold. Then they charge at each other as Gotenks punches and kicks him before blasting him away. Wesker tries a sneak attack, but Gotenks dodges it and slashes him four times. Wesker tries to punch Gotenks in the face, but it doesn't faze him.)

Gotenks: You big idiot. Let us show you how to hit like a real man.

(Then Gotenks kicks Wesker in the chest before grabbing his wrist and throwing him away. Wesker charges at Gotenks again, but gets slashed three times. Wesker tries to attack again, but Gotenks blocks his attack. Then they exchange blows until Gotenks blasts him away.)

Gotenks: You're finished!

(Then Gotenks prepare a powerful energy blast and shoots it at Wesker, killing him. Meanwhile, the rest of the heroes succeed in finishing the rest of the villains and the Union Headmasters. Unbeknownst to them, Commander Taylor manages to escape without the heroes noticing. Then the heroes leave the base as the fight destroyed the place.)

(Cut to Marx, he is seen along with his team and family)

Jorge: Copy Actual - Demon teams have coordinated on the silo.

Price: Dear, report.

Ech0: At the tower, we've hacked the comms. He's up. Stand by.

Daniel: Our victory will be decisive. Together, we put a knife on the neck of history... it's time now for the final cut.

Marx: All stations be advised. Daniel's lighting the fuse. We don't have much time. Where is the rest?

Ech0: At the entry, creating a diversion.

Olesya: Guards are coming our way, Actual...

Marx: Keep 'em busy.

(Meanwhile with Daniel)

Daniel: They came to stop us, but they couldn't resist fighting. This war is 50 years in the making. No more treaties, no more diplomacy. These weapons will be no longer dormant.

(Then Daniel presses some buttons in his computer and looks at it.)

Daniel: Your work is not in vain, father. (sees someone approaching) Show yourself! You're wasting your...

(Before Daniel could finish his sentence, he gets shot by Marx. As he tries to reach his gun, Marx kicks it away.)

Marx: Daniel.

Daniel: Marx. I'm not surprised.

Marx: You're a dead man, Daniel Almagro.

Daniel: (gets grabbed by the collar) I started a war. Killing me won't stop it.

Marx: Oh, I won't kill you. But the fall will.

Daniel: Wait... no. NOOOOOO!

(Daniel falls down and dies.)

Marx: All stations, Daniel is dead. But the missile is still hot. I need the codes, now!

Carlos: Copy, here it comes. Six-One-Five-Seven.

(Marx clicks the mentioned buttons and the missile is stopped.)

Marx: All call signs this net- launch is terminated. Mission accomplished.

(Then James Gunman shows up and Marx tackles him to a subway. Both have a brief fight as they fall down. Marx falls down, wounded and barely dodges a knee drop from Gunsman. Then they exchange blows, but Gunsman gets the best of Marx in his exposed areas while Marx gets nowhere. They both go for a super punch and knock each other back. Then a panel lights up and a train hurdles right at them. Both evade the train at the last second it whips past, creating a very big barrier which none of them can jump over.)

Gunsman: I don't need a weapon to kill you. Our friendship is over.

Marx: You want to see us become like people you hate so much? Divide and conquer the world as they did?

Gunsman: No. I learned from my enemies. Beat them at their own game.

Marx: You have become them... you will destroy the world. This country included.

Gunsman: The world took away everything from me. Everything I ever loved! But I'm gonna make sure we're even. I'm gonna track down anyone who would even think about being your friend, and I'm gonna put their asses in the dirt, right next to Zuri.

(Hatred fills Marx's eyes and they leap at each other again. Marx and Gunsman continue to brawl. Gunsman lands a deadly headbutt and an upcoming train knocks them both to opposite sides. As the train passes, Gunsman picks up a knife, slashes at Marx and backs him up towards the lip of the track. As the train comes in speeding towards them, Marx holds Gunsman off as he pushes the knife across his face.)

Gunsman: This is it for you, friend.

(Marx turns to the train and sees it about to end. He lets Gunsman swing towards him and dodges, backing up even closer to the edge of the track, and Gunsman swings again, but this time, Marx punches his arm, jarring the blade loose and sending it flying to the air. Marx then does a rolling armbar takedown as the knife flips through the air. Marx catches it and slams it into Gunsman's chest.)

Gunsman: (weakly) Well... played...

(Gunsman draws his last breath and dies.)

(Back to the heroes, they realize something.)

Decade: Ozpin and Rorke are still around there.

Diend: We have to stop them.

(Then the heroes are about to proceed, but Kamen Rider Kiva-La turns to the Time Patrol.)

Kiva-La: Aren't you coming?

Gotenks: You can defeat them without our help.

(Then the Time Patrol leaves as they wave at the heroes.)

Gruebe: Alright. What now?

Kick: I'll help bring Logan and Hesh to Hotel Bravo. Rorke is hiding in there. They will finish him off once and for all.

Leon: We will help Icarus Team to turn the Space Station LOKI against what's left of the villains.

????: I hope it's not too late for the party.

(Then the heroes turn to see the non-corrupted Union students.)

Velvet: Coco.

Coco: We may have betrayed ourselves once by walking away from the true path of a hero. But this will not happen. Not anymore.

Shoto: We will put an end to the remaining corruption, and rebuild what Ozpin and his pawns have destroyed.

(Then they go in search for Ozpin until a door opens and the incarnation of Ozma comes out of it.)

Zane: This is the end for you, Ozpin!
