(At Bellwood's Highway, the Night Raid is seen driving a truck where the Alien Dino Thunder Megaforce and Justice League are caged. David is seen playing his flute as everyone else is depressed. David turns to his teammates.)

David: Well, there goes our old home. Nothing is left.

Raymond: Yeah, nothing is left since we got caged.

David: Indeed, we got ourselves captured.

X: I can't believe this happened. We got ourselves captured, and treated like mavericks.

Frederick: You got that right, X. We are new and got captured by those Union Fake Heroes. The question is: How do you guys know them?

Oliver: It was a long time ago. We used to live in Union-Verse, where the Union Fake Heroes live. All they care about is fame, money, slavery, killing powerless people and destruction. The worst part of it is that my world's Superman was with them, besides Wonder Woman, Starfire and Robin.

Ptoir: So that's why they hate you. They failed their missions and you defeated their enemies first.

Hellboy: That's right. We help humanity and others.

Ptoir: And Doctor Strange trusted us to protect our friends.

Hellboy: Exactly, pal.

Santiago: Although we need to get outta here, but how?

????: Gettter Tomahawk! BOOOOOOMERANG!

(Then a tomahawk cuts the truck's door, and then a robot shows up and then a young black haired boy shows up.)

????: (smiles) Hello, guys.

David: Who are you guys?

(Inside Getter-1, James Nagare, Makoto Jin and Leo Tomoe are seen.)

????: I am James Nagare. These are Makoto Jin and Leo Tomoe. We are the pilots of Getter-Robo.

Fernando: And how did you guys get here?

Makoto: We have our ways.

(Back to the heroes, the black haired boy introduces himself.)

????: By the way, I'm Kim Yaoyorozu, brother of Momo Yaoyorozu. And I can get you guys out of here with these.

(Kim pulls out the Thousandriver.)

Raymond: (eyes widen) Hey, that's a Thousandriver.

Rick: What is a Thousandriver?

Ptoir: It's a driver which requires both an specific progrisekey and an specific zetsumerisekey.

Kim: Yep. By the way... (to Santiago and Fernando) I guess these are yours.

(Kim throws the Doubledrivers and the gaia memories for Santiago and Fernando to catch them.)

Santiago/Fernando: Thanks.

Kim: No problem.

(Suddenly a loud thud is heard at the rooftop, and Mine shows up.)

Mine: (smirks deviously) Hello, are you here to bust our old and new enemies out?

(Kim places the Thousandriver in his waist.)

THOUSANDRIVER!

Kim: Of course I came here for this.

(Then he pulls out a zetsumerisekey and a progrisekey before inserting the zetsumerisekey in his Thousandriver.)

ZETSUMETSU EVOLUTION!

Mine: (glares) No, you don't. TATSUMI!

Kim: Hmph! You think your boyfriend can stop you? I thought you were just another pink tsundere motherfucker.

Tatsumi: (comes in and glares) What did you just say?

Kim: (mocking) Ow, did I hurt your girl. I'm so sorry.

Mine: (angry) JUST GET HIM, TATSUMI! DON'T LET HIM TRANSFORM!

Kim: (smirks) Not so fast.

BREAKHORN!

Kim: Henshin!

PERFECTRISE! WHEN THE FIVE HORNS CROSS, THE GOLDEN SOLDIER THOUSER IS BORN. PRESENTED BY ZAIA!

(Kim becomes Kamen Rider Thouser.)

Tatsumi: What? Another Kamen Rider?

Thouser: Kamen Rider Thouser. My power is on a totally different level.

(Tatsumi charges at Thouser while Getter-1 prepares to attack Mine.)

Getter-1: I won't hold back! I'm gonna crush everyone in my front!

(Getter-1 draws his two rifles.)

Getter-1: GO TO HELL!

(Getter-1 shoots Mine, injuring her gravely. Meanwhile, Santiago and Fernando break out of their cells and turn to the Alien Dino Thunder Megaforce.)

Santiago: Don't worry, guys. I'm going to take you guys outta here. Just tell us where they're planning to take you.

Barry: I heard they're planning to take us to Delaware.

Fernando: Why?

Barry: I heard they got a call from Homelander and...

Santiago: Good thing Lucas isn't here. He told me he ran into him once.

Hal: He has?

Fernando: Yep, he told us about having kicked his ass once. He'll probably want revenge on him.

Hal: Oh.

(Then they click their Gaia Memories' buttons.)

CYCLONE!

JOKER!

Santiago/Fernando: Henshin!

CYCLONE! JOKER!

(Tatsumi turns to see Santiago and Fernando transforming into Kamen Rider Double. Suddenly Fernando scratches his head.)

Fernando: Huh?

Santiago: What is it, Fernando?

Fernando: I swear someone just stole our catchphrase before our battle.

Santiago: Don't worry, we'll find our doppelganger soon.

Tatsumi: Who or what are you guys anyway?

Double: Kamen Rider Double! Now, count up your sins!

(Then Thouser summons his Thousand Jacker.)

THOUSAND JACKER!

(Thouser then hits Tatsumi.)

Thouser: You're next.

Double: Bring it on, macho man.

(Tatsumi growls and activates his teigu, transforming into his Incursion form.)

Tatsumi: GRRRRAAAAAH!

(Then Tatsumi charges at Double before shoving him into a wall, bringing him down, and hits him three times with his weapon. Suddenly Thouser kicks him and touches him, copying his ability. Then he pulls the hilt of his weapon.)

JACKRISE!

(Double then takes the Joker Gaia Memory and places it on his Maximum Slot.)

JOKER MAXIMUM DRIVE!

Double: Rider Punch!

(Tataumi charges at Double, but...)

JACKING BREAK!

(Thouser charges the Thousand Jacker with gold and purple energy before launching a golden energy construct of a mammoth's tusk at Tatsumi, hitting him as Double punches his face.)

Tatsumi: NOOOOOOOOOO!

(Tatsumi explodes as Getter-1 had already brought Mine down.)

Double: We have to find Ben and the others.

Leo: We have them with us. Follow us.

(Double nods and follows Getter-1 and Thouser as they look for Ben 10 and the remaining members of the Alien Dino Thunder Megaforce.)

(As the screen fades out, three logos can be shown.)
