B'wana Beast: From the beginning, mankind has faced... villains! Selfishly pursuing their dark agendas. Greed. Domination. Destruction. But always rising to oppose them have been heroes. A breed apart. Men and women of valor, selfishly leaping into the fray. Battling for justice and protecting the innocent. What makes a hero? Courage, powers, these are the questions that would be asked about those unlikely few who stood up to the greatest threat this world ever faced.

Booster Gold: No thanks necessary. It's just a great feeling to know that, when Batman needs help, Booster Gold's at the top of his speed-dial.
Batman: You weren't the first one I called.
Booster Gold: Number two's not bad.
Batman: You weren't the second, either.
Booster Gold: As long as you called.
Skeets: You called him, sir.
Batman: I think you know the way out.
Skeets: We should go before he sics the dog on us again.

Booster Gold: Global meteor strikes? A strange signal from Star City. This all sounds really familiar. Today's not... the third. Listen, I'm pretty sure something big happens today. Huge, in fact.
Batman: Go on...
Booster Gold: Details are a little fuzzy, but I think it involves a diaper truck.
Batman: Ace...

Batman: I've modified my communicator so only those with uncompromised synaptic responders can receive the signal.
Booster Gold: What, like a dog whistle? Cool.

Captain Marvel: A kangaroo and a lizard?
B'wana Beast: Yep.
Captain Marvel: An earthworm and a rhinoceros?
B'wana Beast: Easy.
Captain Marvel: A dog and a... a slightly smaller dog?
B'wana Beast: Do you really have to ask?
Captain Marvel: Awesome!
Ronnie: We're all going to die, aren't we?
Firestorm / Jason: Pretty much, yeah.

Kaboobie, the flying camel from the 60s animated Hanna-Barbera series Shazzan!, appears as B'wana Beast's flying mount.

The cover of Brave & The Bold #28, when the Justice League battle Starro for the first time, is visually referenced in the episode when the heroes attack the alien starfish.

DC Comics' baby characters, Sugar & Spike, get a brief on-screen reference on the diaper truck that Booster crashes into.
