Hourman: Easy, Doc. I ain't made of steel.
Dr. Mid-Nite: I'm afraid none of us are, not any more. The enemy we've always underestimated has finally thwarted us: time.
Per Degaton: The withered remains of the Justice Society of America. How fitting, to find you holed up in a museum with the other antiques!
Batman: The jig's up, False-Face. You'll find behind prison bars that the truth hurts. Excellent detective work, old chum.
Detective Chimp: Don't patronize me... old chum.
Wildcat: Don't grin too wide, Mid-Nite. You'll pop your dentures out again.
Hourman: You're no spring chicken either, you old alley cat.
Hawkman: Hey, we heard you nabbed Captain Cold and Mirror Master last week.
Batman: Just doing my job.
Flash: Too bad four of their henchmen got away.
Batman: I did save the city.
Hourman: You sure you know how to work that gizmo?
Batman: Yes. I built it.
Dr. Mid-Nite: You need to compress the radius after each ping.
Batman: Thank you. I know.
Flash: Let me get in there. I can do it faster.
Batman: (to himself) Some things never change.
Batman: Your mechanized march of madness ends here, Degaton. The only one kneeling today will be you... at the feet of Justice.
Hourman: Good one, kid.
Wildcat: I turn my back on you for two seconds, and suddenly you're 80 years old and covered in robots!

The costume Batman wears during the training flashbacks is his original comic book costume with longer ears.
Injoke: The suspects in the opening sequence are loosely patterned on five of the six suspects in the board game Clue: Professor Plum, Miss Peacock, Colonel Mustard, Miss White, and Miss Scarlet. Mr. Green is the sixth missing suspect.
