(The 10 (Whampire) and Rodimus Prime prepare to fight the Dazzlings' combined Kaiju Form, but then the Rainbooms, Spike and Flash Sentry become Kaijus as well.)

Rainbooms/Spike/Flash: (glare) You won't get away with this, Dazzlings.

????: FOUND YOU, KAIJU SCUMS!

(They turn to see the upgraded Dinobots, Team Tennyson, Dino Thunder Rangers, David, Rick, Jeniffer and Batman coming in.)

Rodimus: (eyes widen) Dinobots?

Grimlock: (glares) Get away from our friends, you monsters!

The 10 (Whampire): (eyes widen) You're back to normal? Also, only the three-headed Ghidorah wannabe is the enemy. The others are our friends.

Kevin: He's right, guys. Those nine kaijus in there are actually the Rainbooms, Spike and Flash Sentry.

Dazzlings: And now you will all face us!

(Grimlock charges at the Dazzlings Kaiju Form, but Aria headbutts him, and so does Adagio, who then looks at Ryan.)

Adagio: (smirks) We found our future slave. Let's use our magic on him!

(Suddenly a portal comes in, and a hand punches Adagio's snout before kicking the Dazzlings' kaiju form backwards, sending them to crash into some trees. Ben sees the figure coming out of the portal, revealing itself as Ultraman Ribut.)

Ben 10: (eyes widen) Whoa!

Grimlock: (eyes widen) Who's that?

Sludge: (shocked) Is he new here?

Rodimus: (shocked) He looks new here.

Scorn: (shocked) He's kinda like an Ultra from the future.

Ribut: That's because I am from the future, also the Megaforce King.

Ben 10/Megaforce: Megaforce King?

Ribut: Allow me to introduce myself. I am Otto Anderson, also known as Ultraman Ribut. Now it's time to face those sirens with my new form.

(Inside of Ribut, Otto Anderson pulls out a Hyper Key.)

ULTRAMAN RIBUT GALAXIUM BOOST!

BOOT UP! MEGAFORCE!

(Then some stone figures appear behind Ribut, they're none other than the 20 Heisei Megaforce Heroes.)

DINO THUNDER, POWER UP! (ULTRAMAN RISE)! TURN UP! JACK IN! IT'S HERO TIME! (GUN SHOTS)! CYCLONE! JOKER! (SONIC'S SPINDASH)! MAGNA POWER! (CHAINSAW SOUNDS)! PROGRISE! STAND BY! MEGAMERGE! (LASER SHOTS)! SHOW TIME! KNIGHTMERGE! IT'S HELLSPAWN TIME! TIME TO SHINE! (SENTRY'S BATTLE CRY)! GALAXIUM!

Otto: Save lives, the light of the galaxy! Ultraman Ribut!

(Ultraman Ribut changes forms.)

ULTRAMAN RIBUT: GALAXIUM BOOST!

(Their eyes widen at Ribut's new form.)

Grimlock: (eyes widen) He's the Megaforce King.

Scorn: That means...

Ben 10: Yes, he's the Megaforce King.

(The Dazzlings get up and see Ultraman Ribut.)

Dazzlings: (snarls) We'll tear you apart!

(They charge at Ribut, who grabs Adagio's head and throws them down.)

Ribut: Time to try something new. Power Drain!

(Ribut drains the Dazzlings' powers, and uses it against them, making them headbutt each other.)

Ribut: Joker Maximum Drive!

(Ribut then kicks the Dazzlings up.)

Ribut: Time to end this! MEGA GALAXIUM BLASTER!

(Ribut then pulverizes the Dazzlings' kaiju form before facing back at Grimlock.)

Ribut: (smiles) I'll be waiting for you, Grimlock. When all nineteen Heisei Leaders and their teams join together.

(He summons the portal and leaves as everyone sees the battle ended.)

Slash: (eyes widen) Well, that was unique.

Sludge: (nods) Who knew he could do that.

Scorn: He is really the Megaforce King.

Ben 10: We need to reunite with others. Let's go!

(They leave Canterlot as the Rainbooms, Flash Sentry and Spike revert back to normal.)

Pinkie: And they say kaijus can't coexist with aliens. Pffft.

(Meanwhile at Dark Omni-Kingdom.)

K. Dormammu: (growls) Damn it, I forgot the General of Darkness died a long time ago. I need a new servant!

(He stands up from his throne, walks towards an evil cybertronia and uses his power to energize it as it activates and his eyes glow.)

K. Dormammu: I want you to destroy... (stern) the Alien Dino Thunder Megaforce and their allies at Civil War Union-Verse. Destroy them all. I'll let Bemstar and Cooler go with you. Do you understand?

????: (bows) Understood. I, Scorponok will destroy those Megaforce Heroes.

(Then both Bemstar and Cooler come beside Scorponok.)

Bemstar: (bows) We will destroy all heroes, master.

Cooler: (bows) We will prevail for you.

K. Dormammu: (nods) Good, now go and kill those heroes.

(He summons the portal, and the three villains go through it as Kaiser Dormammu goes back to sit on his throne and sees his enemies reuniting with their teammates.)

K. Dormammu: (stern) Don't think you're gonna win, Grimlock and Tennyson. I will become stronger than each one of you, no one will be safe from me and Virgolial. Especially Makoto Fuwa. At this moment Horobi must be fighting those pesky heroes in his Ark Scorpion form. Anyway. The children of Bruce and Ben's arc is finished. Now it's the second arc. Let's see if you survive from me.

(As the screen fades out, an announcement is heard.)

ULTRAMAN RIBUT!
