(In Bellwood, everyone is seen having a peaceful day ever since the Alien Dino Thunder Force saved them. The citizens are minding their own business when suddenly they hear a roar and turn to see Solomon Grundy rampaging through the streets.)

S. Grundy: Grundy crush Superkid and little bat!

(Then Superboy (Jon Kent) and Batgirl come in.)

Batgirl: Are you ready?

Superboy: (nods) You bet I am, let's defeat this zombie.

(Grundy charges at them, and Superboy charges as well, only for the villain to dodge. Batgirl throws some batarangs at him, but Grundy blocks them like they're nothing, and then he climbs to the top of a building.)

Grundy: Grundy smash kids from above!

(Grundy is about to pounce on them, but Superboy flies towards him and punches him backwards. Batgirl slashes off one of his arms and kicks him to a wall.)

Grundy: (gets up and glares) Brats hurt Grundy! Grundy kill you dead!

(Grundy pulls out a butcher knife and throws it at them, but Superboy grabs it. Batgirl kicks his nose and Superboy punches him to the opening area.)

Superboy: Time for the Super Finish!

(Solomon Grundy pulls out a tombstone and throws it at Superboy, who simply charges at him, breaks the tombstone, grabs him in the neck and uppercuts him into side space before flying up and slamming him back to the ground, knocking him unconscious.)

Superboy: You're lucky you're a zombie.

(Then Batgirl approaches him.)

Batgirl: Let's get back to Ben's Headquarters and tell him that we defeated a Chaos Avenger.

Superboy: (nods) Right.

(Then they return to Ben's Headquarters/Tennyson Mansion, and suddenly a portal opens up, revealing some unwanted visitors from the past.)

Rias: So this is where that bastard Tennyson lives now, and where Superman and Asuna died from their pathetic mission.

Satsuki: (monotone) They already failed us, it's our turn to have our vengeance against those aliens and traitors.

Tatsumi: Superman and his weak Regime are dead, and so is Asuna. Like you said, Satsuki... they already failed us.

Mine: Hmph, they are pathetic anyway.

Lubbock: There are big chances for us to capture both Ben 10 and Powergirl. And once we do it, I'll have Karen Starr to myself, and then we kill those aliens and traitors.

Najenda: (smirks) Heh, we from Union shall rise again and have our triumph.

Leafa: (stern) I'll kill that robotic alien dinosaur for turning my brother against me and killing my future sister-in-law.

Blake: I shall have my claws on them, especially Ryan's brother.

Yang: (smirks) Can't wait to beat the "Yang" out of them.

(Everyone looks at Yang with a deadpanned and disappointed look.)

Yang: (chuckles) What? It's funny.

Ruby: Yang, just don't.

Yang: (pouts) Hmph.

Enterprise: (monotone) I'll have my vengeance against that brute Dinobot.

Endeavor: (stern) I will burn them alive for what they put me through... (angry) IN THE FUCKING PRISON!

Bakugo: (angry) I WILL KILL THOSE EXTRAS ONCE AND FOR ALL!

Omni-Man: And we know the drill, everyone. Operation... Destroy Alien Dino Thunder Force.

(They go to the city streets as they have a goal against the Alien Dino Thunder Force.)

(Meanwhile in the Pacific Ocean, everything seems quiet until a mecha is seen flying in high speed, revealing to be Mazinkaiser himself.)

Mazinkaiser: I can feel them.

(Then he sets out to Bellwood to fight his arch-rival Ben Tennyson.)

Mazinkaiser: I'm coming for you, Ben Tennyson!

(Unbeknownst to Mazinkaiser, Getter-3 is watching him underseas as the screen fades out.)
