(After the heroes get out of the underground base, they see some unwanted figures, they're the Chaos Avengers and the Brotherhood of Shadows.)

Grimlock: You again?

Shinnok: (smirks) Indeed. And as you can see, I've got some new friends here.

Ben 10: The Chaos Avengers?

Shinnok: That's right. Dormammu and I teamed up to destroy you all.

Ichigo: (angry) You couldn't be lower than that. Like turning on the Elder Gods wasn't enough, you join the Lord of the Chaos Dimension.

Shinnok: And once we're done with you, the world as you know... no, the universe you know... WILL BE NO MORE!

(Then Kamen Rider Psyga steps in.)

Psyga: S'up, losers.

White Dino Ranger: David?

Rick: You know him, David?

Psyga: Yes, father. We met once in Kamen Rider Cyclone: Civil War.

Vice: Hey, so you're David Taylor, son of Rick Taylor from Splatterhouse.

Revi: Vice, please.

Shinnok: Enough talk. It's time for battle.

(Then Ben 10 becomes Heatblast while Kamen Rider Ichigo charges at Shinnok and kicks him. Ben 10 shoots some fireballs at him before kicking his face with a flaming kick.)

Shinnok: You'll pay for this.

(Then Ben 10 changes to Big Chill and freezes Shinnok as Kamen Rider Ichigo jumps to the sky.)

Ichigo: RIDER KICK!

(He kicks across Shinnok and his body crackles.)

Shinnok: I'LL BE BACK, BEN AND SHIMIZU. I WILL...

(Then Shinnok's body explodes.)

Ben 10: I'm still impressed about how Kamen Riders kill their enemies.

Ichigo: Awesome, isn't it?

(Meanwhile, Kamen Rider Nigo jumps to the sky as well.)

Nigo: RIDEEER KICK!

(Kamen Rider Nigo kicks across Brandish Myu and she explodes. Then Kamen Rider Ichi-Gata and Kamen Rider Blade look at each other.)

Ichi-Gata: Let's do this!

Blade: Right!

Cycloneriser: Rocking Spark!

B. Buckle: Kick! Thunder! Mach! Lightning Sonic!

H. Gaitlinger: 10! 20! 30! 40! 50! 60! 70! 80! 90! 100! Full Bullet!

S. Driver: Orange Squash!

Decadriver: Final Attack Ride: D-D-D-Decade!

OOO. D: Scanning Charge!

Drake: Rider Shooting!

Zecter: Rider Shooting!

Wizard: The Finale!

Wizardriver: Chōīne! Kick Strike! Saikō!

Zero-One D: Rising Impact!

ShotRiser: Bullet! Shooting Blast Fever! Dash! Rushing Blast Fever!

Thousandriver: Thousand Destruction!

ForceRiser: Flying Dystopia! Sting Dystopia! Zetsumetsu Dystopia!

(Then all Kamen Riders jump to the skies, except for Build and Drake, and then they do a multiple Rider Kick which destroys all of the Chaos Avengers. Then Rick looks into the skies.)

Rick: Jennifer... my time has come... my only regret... is having driven our son to his death... so... young...

Psyga: Father... I forgive you...

(Then the villains explode.)

Jacqui: How did they do that?

Grimlock: That's a long story.

(Then Dormammu appears.)

Ben 10: (stern) Dormammu...

Dormammu: So the Alien Dino Thunder Force and the Special Forces joined forces. Well, since Shinnok failed, it's my turn to wreak havoc.

Raiden: So you're the one who made an alliance with Shinnok.

Dormammu: Indeed, and at this moment, Quintessa Prime has already released the revived predacon.

Grimlock: (shocked) Predaking?

(Meanwhile in the city, Predaking is seen destroying everything in his way.)

(Back to Dormammu and the heroes.)

Dormammu: Good luck trying to stop him! HAHAHAHAHA!

(Then Dormammu disappears.)

Ben 10: Oh, Dude. We need to reach the location and face this Predaking before it's too late.

????: I can help you with that.

(Then they turn to see Cosmic Virgo.)

C. Virgo: I can help you to arrive at Predaking's location.

Ichigo: Okay, I'm confused. First, giant robots, now a talking kaiju?

C. Virgo: Let me introduce myself to you.

(Then Cosmic Virgo teleports himself and the heroes to the place where Predaking is.)

C. Virgo: I am Cosmic Virgo, the Celestial Victorian Dragon, at your service.

Grimlock: Cosmic Virgo?

C. Virgo: I'm Virgo's alter-twin. And I am bringing you to stop Predaking's rampage.

Oscar: Let's kick his ass.

Yellow Dino Ranger: Yeah let's do this.

Heroes: ALIEN DINO THUNDER SPECIAL FORCES TEAM UP!

C. Virgo: And I also brought some special allies.

(Then they appear, revealing to be Bumblebee, Hot Rod, Doctor Strange, Jennifer Willis, Kamen Rider V3, Ultraman, Ultraman Taro, Gundam RX-78, Gundam Knight, Batman and the Gotham Knights.)

Bumblebee: S'up, I am Bumblebee, and this is Hot Rod.

Grimlock: Your voice returned, Bee.

C. Noir: Did you see that?

Invincible: They're from...

C. Virgo: The Omniverse. Many heroes come from different Omniverse to help each other and work together. I'm also known as the Omniverse King of Heroes.

Hot Rod: Thanks for bringing us here.

C. Virgo: No problem.

(Then Doctor Strange uses his magic to bring Rick Taylor and David Taylor back to life, and then they see Jennifer.)

Rick: (shocked) Jennifer?

Jennifer: Rick.

David: Mom.

Jennifer: David.

(Then the three have a friendly hug as Rick looks at Doctor Strange.)

Rick: Are you the one who brought Jennifer back to life?

Dr. Strange: Yes.

David: Thanks, Doctor Strange. (to Jackson) Oh, and sorry for attacking you, my friend.

Jennifer: I never thought you could have a friend, David.

David: It's a long story, mom.

(Then another portal is opened, revealing Ultraman Great, Gundam F91 and Kamen Rider Black RX.)

U. Great: Thanks for allowing us to ally with our friends.

C. Virgo: No problem.

(Then Doctor Strange revives Optimus Prime with his magic.)

Bumblebee: Optimus?

Optimus: B-127? I haven't heard your voice during years.

(Then the heroes turn to Cosmic Virgo.)

C. Virgo: Now go and save this world from Predaking the Union Fake Heroes.

David: Alright. (draws his phone and clicks 3-1-5) Henshin.

Driver: Complete!

(David becomes Kamen Rider Psyga)

C. Virgo: I better get going. See you heroes later. Good luck.

(Then Cosmic Virgo goes through the portal and leaves.)

Ben 10: Okay, guys. Ready for the final battle?

Heroes: YES, WE ARE!
