(Batgirl then grabs Amazon Alpha Zero's head and snaps his neck, killing him.)

(Everyone else is seen still fighting while Ben 10 (Rath) is seen fighting Terry/Kamen Rider Imperial Demons.)

(They charge at each other, and punch each other until Ben punches Terry's chest.)

CHARGE! DEMONS FINISH!

(Imperial Demons shoots out a rope of Demon String to encase Ben 10 (Rath), and throws him around. He then approaches Ben as he smiles evilly.)

I. Demons: It's over, Tennyson. Time to make sure you won't exist in this wretched world. But don't worry, your siblings and family will join you after that.

(He laughs evilly until someone kicks him. It's Ozpin/Kamen Rider Evol.)

I. Demons: Who the hell are you?

Evol: Those who are about to die by my hands don't need to know my name!

(Imperial Demons charges at Evol and tries to punch him, but he grabs his fist and punches him in the gut before throwing him to Ben 10 (Rath), who punches him multiple times, and then he uses his Talon to break his Demons Driver, forcing him out of his transformation.)

Terry: No, this can't be happening. (faces back at Ben 10) GRR! YOU'RE GOING TO PAY FOR THIS, TENNYSON!

Evol: Focus on me, human!

(Evol prepares his finisher.)

READY, GO! BLACK HOLE FINISH! CIAO!

(A miniature black hole is generated behind him. The black hole then compresses into halo-like rings of energy as Evol delivers a powerful flying kick to Terry, sending him into the black hole which kills him after a period of time. Power Girl approaches Ben, who reverts back to normal.)

Power Girl: (worried) Honey, are you okay?

Ben 10: I'm fine, Karen. (grabs her hand) I've got an announcement to make.

Power Girl: (curious) What is it, Ben?

Ben 10: Ever since I broke up with Asuna, my brother Ryan wanted me to reunite with you.

(Flashback)

(At Union-Verse, Professor Paradox is seen building a portal while Ben 10 is watching until he gets a visit from Ryan.)

Ryan: (smiles) Hey bro, what's up?

Ben: (smiles) Professor Paradox is building a portal for me and my friends.

Ryan: (smiles) Let me guess, to reunite with Karen.

Ben: (eyes widen) How did you guess it?

Ryan: Come on bro, me, Ace, Iris, Henry and Mika talked about this ever since they left. Just tell Karen how you feel.

Ben: What if she rejects me?

Ryan: (smiles) She's not gonna reject you. After all, we are the grandsons of Max Tennyson of the Plumbers. While she's the member of Justice Society of America, ya both are like CEOs to both Aliens & Metahumans. We all want beings to coexist, right?

Ben: Yeah.

Ryan: Hmm... (has an idea) A-ha. Wait here, I'll be back.

(He runs back downstairs as he goes to the living room, he hears footsteps as he sees Lucy watching Ryan going downstairs looking for something as she faces back at Ben.)

Lucy: Hey Ben, what is your brother doing?

Ben: I don't know...

Lucy: So, Ben... me and the girls are gonna confess our feelings to your brother... (blushes) if you don't mind.

Ben: (chuckles) Of course, you girls are the only ones who cared about my brother.

Lucy: (smiles) Alright, we'll be in touch!

(Then Ryan comes back upstairs, bringing a black little box.)

Ben: (confused) What is this?

Ryan: (smiles) Open it.

(He opens and sees a diamond ring.)

Ben: (shocked) Ryan... is that?

Ryan: (nods) Yeah, it's for Karen. Tell her how you feel.

Lucy: (smiles) And she'll accept your feelings.

(Flashback Ends)

Ben: Ryan told me everything back then, so... Karen Starr.

(He kneels down and opens the small box as it shows the engagement ring, Power Girl gasps as her tears come out of her eyes. Then Ben smiles at her.)

Ben 10: (smiles).Will you marry me?

(She smiles in tears as she smiles at him.)

Power Girl: (smiles in tears) Yes, a thousand times yes.

(Ben puts a ring on her finger as he stands back up and he kisses her lips, he hugs her waist and Power Girl hugs him around his neck. They pull back each other while their saliva strings, they smile at each other.)

Ben: (smiles) I love you, Karen Starr.

Power Girl: (smiles in tears) I love you too, Ben Tennyson.

(Evol reverts back to Ozpin, and opens a portal.)

Ozpin: Well, I guess my work here is done. Time to go back to my world.

(Ozpin walks as the portal closes, and Ben 10 has a kiss with Power Girl while the rest of Alien Dino Thunder Megaforce are still fighting the Kaotic Avengers and Marvel Fake Heroes.)

(Meanwhile at Disney Studios, Jafar sighs in frustration.)

Jafar: It looks like the Marvel Heroes are returning to normal. I guess it's time for Plan B.

(Jafar uses his magic and summons a Kaiju which is a combination of MechaGodzilla and Iron Man.)

????: (roars)

Jafar: Destroy all of the Alien Dino Thunder Megaforce once and for all, Iron Kaiju!

(Iron Kaiju nods and as the screen fades out a scene of all Megaforce heroes defeating their enemies is shown.)
