Cop: You'll get life for this.
Kru'll: Bah! Your prison will be dust long before Kru'll the Eternal is!
Batman: Sorry to call you away from your nightly workout, Wildcat. but I'm gonna need all the help I can to take down this escaped con.
Wildcat: Well, he better be as tough as you say, 'cause I've got 567 pushups to get back to.
Booster Gold: Skeets, old buddy, you know what I got to do?
Skeets: I know what you should do, sir.
Booster Gold: I gotta team up with Batman!
Skeets: Or that.
Batman: Sorry, Punch and Jewelee, but you'll find there won't be much to laugh about behind prison bars.
Batman: How did you track me here?
Booster Gold: In the 25th century, the Batcave's a historical attraction. With a roller coaster. In 400 years or so, I'm gonna hurk right up there.
Batman: Bending legitimate scientific equipment to your evil will. You fiend.
Kru'll: A super collider is one aspect of particle physics that even a caveman can enjoy. Smashing things against a wall.
Batman: I'm glad we could work together, Booster.
Booster Gold: Wow.
Batman: My thoughts exactly.

Although the character of the immortal caveman presented here is named "Kru'll," and bears a resemblance to Fawcett's comic character King Kull, his origin is that of Vandal Savage (see character bios). However, his personality and tactics are much different than Savage's.
