In several shots, the prisoners don't appear in the same tubes during the battle in the time tunnel chamber. For instance, Batman is against a pillar and Mongul misses him with a punch, and the "space pirate" from the arena is seen even with Mongul. When Jonah jumps and fires his gun, the same alien is now even with Jonah, much closer to the time tunnel. When Jonah shoots Mongul, a gray-skinned alien with a movies Alien-type head can be seen to his right. Mongul throws a piece of floor at Jonah and the same alien is seen to Jonah Hex's left. And when Batman is thrown against a tube at floor level, a short bow-legged alien is seen to his right, but a few scene cuts later as Mongul calls them unworthy, the same alien is on the second tier of tubes.
Other villains appearing without dialogue: Stompa, Zebra-Man
Batman: Listen, strength comes in numbers. We can survive this if we work together.
Arges: Yeah? The guy in the last battle said the same thing.
Batman: How'd that work out for him?
Gordanian: Ask him yourself. (points out a pile of broken armor)
Black Lightning: Pretty fast for a big guy! But you want to beat the Outsiders, you've got to be lightning fast!
Arges: Didn't ask you to sit.
Jonah Hex: That's because you ain't got no manners.
Batman: Two days ago, Zebra-Man, you told the parole officer you would never use your magnetic powers for evil again. Looks like you'll never change your stripes.
Jonah Hex: I like big guys like you, Mongul. 'cause when you fall, you make a real big racket. And you will fall. That's my word.
Steppenwolf: The outcome is always the same for those who take on Steppenwolf--defeat.
Batman: Then you're about to be humbled by the hammers of Justice.
Lashina: You gonna shoot an unarmed opponent?
Jonah Hex: Fair's fair.
Lashina: Besides, hand-to-hand combat is so much more... personal.
Jonah Hex: You can tell a lot about a fellow by the way he fights.
Lashina: So, what do you know about this fella?
Jonah Hex: Give me a few more swings, and maybe I'll tell ya.
Mongal: Mongul! Help!
Mongul: What's that? I can't hear you over the galloping! (laughs)
Jonah Hex: (as Mongul prepares to punch him) Go ahead. Face ain't gonna get much worse than it already is.
Jonah Hex: You reckon there's a doodad in your belt that'll bring down a raging bull like him?
Batman: I reckon there is.
