(Kamen Rider Gold Drive, his mini-army and the Chaos Avengers are seen in their headquarters as they discuss their plans for the final attack.)

G. Drive: It's just a matter of time until the Union Fake Heroes find us.

C. Widow: You mean...

Megatron: You have a point, human. It's time to put an end on this!

Demons: Okay then. Chaos Avengers...

C. Avengers: Assemble!

(Inside of Union Academy, the Headmasters are completely pissed about the deaths of Rias and her peerage.)

Sirzechs: DAAAAAAMN IIIIIIIIIT!

Michael: This is no good.

Ozpin: That's it. We'll stop them! Right here, right now!

(Outside of Union Academy, Kamen Rider Gold Drive is seen along with his army and the Chaos Avengers as they prepare to attack.)

G. Drive: Kevin.

(Kevin approaches his commander as he is seen wearing a Federation uniform.)

Kevin: Called me, sir?

G. Drive: Yes. You'll command the soldiers to plant down some mines, and fire some EMP waves as well. Those bastards must not get to contact their troops.

Kevin: (salutes) I won't let you down, sir! (to the soldiers) Soldiers, let's get to work!

(The soldiers draw their weapons and drive their vehicles, which are similar to the ones used by the Federation. As they go to do their job, the Chaos Avengers get in their fighting stances as they see the Union Fake Heroes arriving.)

G. Drive: (to Demons) At your command.

Demons: CHAOS AVENGERS... (smirks) Assemble!

(Then the Chaos Avengers charge at the Union Heroes.)

Ozpin: (angry) Union, ATTACK!

(The Union Fake Heroes charge as well. The only ones who didn't charge at the Chaos Avengers are Nebula, Sona, Glynda, Mt. Lady, Ichika and Yumi. Kamen Rider Gold Drive notices that and approaches them.)

(Meanwhile Iron Patriot is seen shooting down all huntsmen and huntresses.)

I. Patriot: Oh yeah, I love killing these Union brats.

(Venom becomes King Venom, grabs Nora with his tail, bites her arm off, and then he eats her whole body while her blood spills out.)

K. Venom: She tastes good.

(Sona is seen simply watching her own peerage being eaten alive by King Venom, who also rips Saji's head off.)

Sona: They deserve it.

(King Venom then proceeds to grab Dew, Gwen and Octavia with his tail.)

Dew: (grunts) Put us down.

Gwen: LET US GO, YOU MONSTER!

K. Venom: Us, monsters? YOU are the real monsters around here. We're simply cleansing this world up.

(Back to Zane's friends, they see Gold Drive approaching them.)

G. Drive: Hello, friends.

Nebula: Zane? Is that you?

G. Drive: Yeah, that's me.

Nebula: If possible, could you let us join you?

Yumi: We really want to be at your side.

Sona: Please, let us be with you.

(Nebula's teammates and Yumi's teammates, besides Houki, Cecilia, Charlotte, Laura and Rin get shocked.)

Dew: NEBULA! Are you crazy? Joining those villains to conquer the world?

(The six don't listen, and then Gold Drive smirks at them.)

G. Drive: Then it's decided.

(Then Kamen Rider Demons injects a serum at Yumi while Iron Patriot presses a button and a purple Kiryu appears. Red Samurai Ranger gives some drivers to Glynda, Nebula and Sona.)

R.S.R.: Use these.

G/N/S: Thanks. Henshin!

(And finally Megatron plants a Cloneblade on Mt. Lady.)

Murakumo: (angry) WHAT DID YOU DO TO YUMI?

G. Drive: You'll see your new improved leader.

(Then Yumi is seen with a white hair and unleashing a powerful blizzard.)

Yumi: I feel more powerful than I expected. I'm stronger than my weak self.

G. Drive: Now, how about you kill them, my beautiful Killer Frost?

Yumi: (smirks) Killer Frost, huh? I like that name. I'll execute my teammates.

(Then Yumi/Killer Frost creates an ice blade and prepares to kill her former teammates.)

Yumi: (evil smile) Don't get the wrong idea. I still maintain my sense of justice. Now say goodbye.

(Yumi slices their heads off, and their blood spills.)

(The Chaos Avengers are seen having clear advantage. Glynda/Kamen Rider Marika is seen overwhelming Ironwood while Sona/Kamen Rider Calibur does the same to Serafall and Nebula/Kamen Rider Idunn kills her former teammates..)

Glynda/Marika: You're not fit to command, James. You never were.

Nebula/Idunn: It really has to end, and you three are no longer my friends.

Sona/Calibur: We only shared blood, Serafall. We were never sisters.

(Ichika is seen piloting the purple Kiryu and blasts his ex-girlfriends into dust.)

Ichika: This is for abusing me constantly for no reason!

(Mt. Lady in her Cloneblade form, slashes Endeavor in half.)

Mt. Lady: Rei will be much better without you!

(Meanwhile Gold Drive's army is seen firing EMP waves, rendering the Union Academy unable to call more troops while the mines are seen already planted around the school. Kevin communicates with Gold Drive. )

Kevin: The mines have been planted, sir.

G. Drive: (intercom) Good. Now leave the area. We're going to blow them all up.

Kevin: Understood.

(Back to the Chaos Avengers, they are close to their victory as Zane's former family witnesses that.)

Greg: This can only be a nightmare?

(Suddenly Megatron slashes Zane's former family in half.)

Megatron: Of course it's a nightmare... for you!

(Then Gold Drive's army approaches the Chaos Avengers.)

G. Drive: (smirks) Farewell, Union Academy!

(Then the Union Academy is blown up, and the only survivors are the six students who are Zane's friends.)

G. Drive: VICTORY!!

(The Chaos Avengers celebrate their victory, and then Eternal Dormammu comes I along with Slice.)

E. Dormammu: Excellent work, Chaos Avengers. Now this world is ours. All kinds shall serve us as slaves.

G. Drive: What should we do now, Lord Dormammu?

E. Dormammu: You and your friends will go to the Dark Omni-Kingdom, where you will be awaiting your next mission and meet the Darkaiju Legions.

G. Drive: Understood. (to his allies) Let's go.

(Zane's friends nod as they go to the Dark Omni-Kingdom, and Eternal Dormammu laughs evilly.)

E. Dormammu: THIS WORLD IS MINE!
