Bruce Wayne: [from trailer] I'm putting together a team of people with special abilities. See, I believe enemies are coming...
Barry Allen: Stop right there. I'm in.
Bruce Wayne: You are? Just like that?
Barry Allen: Yeah, I... I need... friends.
Bruce Wayne: Agreed.
Barry Allen: [holds up batarang] Can I keep this?
Superman: Do you bleed?
[throws Batman into a wall]
Steppenwolf: No protectors here. No Lanterns. No Kryptonian. This world will fall, like all the others.
Bruce Wayne: [sees the Flash suit] Silica-based quartz sand fabric. Abrasion resistant. Heat resistant.
Barry Allen: Uh... yeah, I do... competitive ice dancing.
Bruce Wayne: It's what they use on the space shuttle to prevent it from burning up on re-entry.
Barry Allen: I do... very competitive ice dancing.
Arthur Curry: You tell anyone about this, I will bring every piranha I know after you!
Alfred Pennyworth: [to Bruce] I miss the days whens one's biggest concern is exploding wind-up penguins.
Bruce Wayne: I believe that an enemy is coming from far away. I'm looking for warriors, this stranger. Others like him. I'm building an alliance to defend us. It's very important that I see this man.
Bruce Wayne: The world needs Superman... the team needs Clark. He's more human I am. He lived in this world, fell in love, had a job. In spite of all that power.
Bruce Wayne: [from trailer] Arthur Curry. I hear you can talk to fish.
Bruce Wayne: Superman was a beacon to the world. He didn't just save people, he made them see the best parts of themselves.
Barry Allen: I eat a lot of snacks to fill this black hole. I'm a snack hole!
[after been beaten by Superman and is thrown to the ground]
Batman: I think something is definitely bleeding.
Steppenwolf: For Darkseid!
Superman: [to Flash] Slowpoke!
Diana Prince: You wanted me to be a leader. But leaders get people killed. So I follow, always.
[Arthur Curry rescues a man from drowning]
Arthur Curry: [takes a bottle of whisky] It's on him!
[seeing Superman alive again]
The Flash: Pet Sematary!
Lois Lane: There are heroes among us. Not to make us feel smaller, but to remind us of what makes us great.
Mera: Your mother would have gone to the surface world to stop that thing. But she's not here, so it has to be you.
Bruce Wayne: [to Wonder Woman] Superman was a beacon to the world... Why aren't you? You're an inspiration, Diana. You don't just save people; you make them see their better selves. And yet, I'd never even heard of you until Luthor lured you out by stealing a picture of your dead boyfriend. You shut yourself down for a century, so let's not talk about me moving on!
Lex Luthor: I was just celebrating the return of God. He burst out of the ground!
Queen Hippolyta: Listen to me, Diana.
[fires a flaming arrow]
Superman: I'm a big fan of justice!
Superman: Well I believe in truth... but I'm also a big fan of justice.
Bruce Wayne: I had a dream. It was the end of the world.
Barry Allen: [after Cyborg briefly leaves during the first battle against Steppenwolf] Did he just bail on us?
Lois Lane: This is what we know: The world has grown dark, and while we have reasons to fear we have the strength not to. There are heroes among us, to remind us that only from fear, comes courage. That only from the darkness, can we truly feel the light.
Black Clad Alpha: This is man's best hope. Down with the modern world, back to the dark ages and the safety of holy fear.
Superman: [while choking Batman] Tell me, do you bleed?
Bruce Wayne: Did Steve Trevor tell you that?
Arthur Curry: Mah Man!
Diana Prince: You have to learn to move on.
