(Jack is seen with Ben and Rex walking through Tokyo Streets as he turns to them.)

Jack: So? How did you two meet each other?

Rex: We met first in a crossover special.

Jack: Which is?

Ben 10: Ben 10/Generator Rex: Heroes United!

Jack: So Cartoon Network wanted to make a crossover.

Rex: First time.

Jack: I heard that DC made a crossover between Batman and Scooby-Doo.

Ben 10: You mean DC Universe? I have been in there once.

Rex: Yeah, it looks like Warner Bros. tends to go too far with the DC movies, especially when they involve blood and violence.

Jack: Wait, you don't like blood and violence?

Ben 10: Nope. I sumply beat my enemies normally. And the only reason why Gwen and Grandpa thought I went rogue was because of my friendly rival Kevin, and my evil counterpart Albedo,

Rex: I remember that Superman can either be a hero or a villain. Batman simply follows the laws, and tends to be emotionless and uncaring.

Ben 10: And Wonder Woman? She doesn't know how the modern world works.

Jack: That's why I prefer Marvel, especially Spider-Man. He always proves why he's the greatest superhero.

Rex: What about Zane, Adam and Ace? I heard Ace is my counterpart's cousin.

Jack: Yeah, and they don't trust the Justice League. They prefer the Avengers, especially the ones from MCU.

Ben 10: Cool. And I heard my counterpart is a great hero as well.

(Suddenly some crashes are heard as Ben and Rex look to see their archenemies Vilgax and Kleiss.)

Kleiss: Hello, Rex. We meet again.

Vilgax: You too, Ben Tennyson. Now where is the Omnitrix!

Jack: He always wants to get the Omnitrix, huh?

Ben 10: Yeah, he is the toughest enemy I ever faced.

Jack: So was our Vilgax.

Kleiss: So you are friends with an Ultra now, huh?

Vilgax: I thought they were just myths.

Jack: Guess what, idiot. We are not!

Vilgax: Who did you just call idiot?

Jack: You!

Vilgax: You will regret this! Prepare for a beatdown! You too, Rex and Tennyson!

(They get in their fighting stances, and Ben activates his Omnitrix.)

Ben 10: It's hero time!

(Ben 10 transforms into Four Arms while Jack becomes Ultraman Jack.)

Ben 10 (Four Arms): Let's get ready to rumble!

(Ultraman Jack punches Vilgax, and then he blasts him away while Ben 10 starts pounding Kleiss.)

Kleiss: I hate this.

Ben 10 (Four Arms): Prepare for more!

Kleiss: VILGAX!

Vilgax: Right back at ya.

(Suddenly, Vilgax presses some buttons, and then the Blizzard Force Megazord is summoned.)

U. Jack: What is this?

Vilgax: Zetton told us to use this Blizzard Force Megazord.

Kleiss: Now we can beat you!

(Vilgax and Kleiss enter in the megazord and command it to freeze Ultraman Jack down, and then they slash him.)

Ben/Rex: JACK!

(Suddenly some cannon blasts hit the Blizzard Force Megazord.)

????: Oh yeah!

Vilgax: What the... who is this piece of junk?

Kleiss: I don't care, let's get him!

(The robot shoots his cannon blasters again, and eventually destroys the Megazord, forcing Vilgax and Kleiss to leave the cockpit. Then the robot changes to a human size and smirks at them.)

Ben 10: Who or what is that?

Rex: He looks like a robot.

????: For your information, I am a cybertronian. You may call me... AEROBOLT, LEADER OF THE AERIALBOTS!

Kleiss: What... an aerialbot? Here?

Vilgax: Let's make him pay for this insult!

(They charge at Aerobolt, who shoots some missiles and blows them away, and then grabs their heads and slams them together before kicking him away.)

Aerobolt: Now for the grand finale, my friends.

U. Jack: Hey, Aerobolt.

Aerobolt: Yes, my Ultra Friend?

U. Jack: Let's blast them away together and tie them up. My friends and I need to bring them back to television. The children want them back.

Aerobolt: Ah, so that's why Cartoon Network Characters are missing. Okay, let's do this.

Vilgax/Kleiss: Uh-Oh!

Aerobolt: Uh-Oh indeed.

(Then they combine their blasts and knock Vilgax and Kleiss out before making their victory pose.)

U. Jack: Another mission complete.

Aerobolt: Indeed, my friend.

Ben 10: Hey, that was cool.

Rex: Yeah, that was cool. Even better than DC Universe.

Aerobolt: Indeed, my friends. That's what heroes do.

U. Jack: Okay, let's bring those villains back to their world. We can't let them escape.

(At Zetton's Lair)

Zetton: DAMN THAT ULTRAMAN JACK! HE WAS SUPPOSED TO BE DESTROYED! But that's okay, Mojo Jojo and Yellow Diamond will fight their opponents soon! Hahahahaha!
