Well, when Kalibak appeared on the JL cartoon, there was no mention of Darkseid or Apokolips, so technically it's a correct answer. But I'll take another guess: Glorious Godfrey?

Godfrey was exactly who I was looking for. Thread's all yours. Though Kalibak being somehow affiliated with Darkseid was made very clear on JL before the Supeman Revenge Squad episode(I love the Kalibak/Lobo fight from that :-D as well as the Vandal Savage stuff in the future with Superman).

I don't recall Kalibak appearing on JL before the SRS episode. Ah well, my memory isn't what it used to...what was I talking about?

New question. DC characters Speed Demon, Jack B. Quick, and Pterano Don Juan were all based on what Marvel character?

Quicksilver?

I've never heard of any of these characters, but Speed Demon seems too obvious an answer, and Quicksilver is the only other speedster I can think of in the Marvel U.

Yup, Orin gets it. Speed Demon (from Showcase #63) and Jack B. Quick (Justice League of America #87) were parodies of Quicksilver as a member of the Avengers; Pterano Don Juan (Showcase #65), as one of the Brotherhood of Evil Mutants.

All yours, Orey.

Uh oh, Other Aquaman has control over two trivia threads. What will Mr Hatch do with them?
Stay Tuned.

Same Bat-time, Same Bat-channel.

New question -
In one of my favourite JLA stories, The Key traps the members of the League in a shared dream, with the purpose that they find each other in the dream and break out, unleashing enough energy to transform him into a god (or something like that). In this dream, Wally got a speed-suit from Fastbak, Krypton was never destroyed but Kal-El became a Green Lantern instead of Superman, Wonder Woman was perpetually fighting Nazis, and so on. Bruce Wayne was a retired old man, but Batman and Robin lived on. Who were Batman and Robin?

Martian Manhunter and John Stewart.

I honestly don't know.

Kalibak's first appearance on Justice League was in the episode 'Twilight', wherein Darkseid and Brainiac team up to take down Superman. Darkseid, of course, betrays Brainiac, only to take a beating from both Orion and Superman before Brainiac's asteroid field headquarters blows up.

As for the memory bit, try some ginko biloba.

As for the question, Dick Grayson and Tim Drake..?

JTR - definitely wrong.

Monitor - Good guess, and definitely one I expected, but not it.

Paris Hilton and Nicole Ritchie?

Bat-tra and Rodan ??? (a near-perfect fit, I'd say).
