Nope, neither Showcase nor All-American. All-American didn't start with super-heroes until its sixteenth issue (unless you count the sci-fi strip Ultra-Man, which started in #8) and it had super-heroes right up until the end (although the Western feature Johnny Thunder took over the cover for the final three issues). The comic I'm looking for was a super-hero book right from the first issue, and was home to several super-hero features (although only one was ever on the cover; not even Superman in Action Comics can say that!).

How about... Challengers Of The Well-Known. You know, the ones who dare to drink water. The ones who proudly state they are sure the Earth is round. The ones who are also pretty sure that 2+2 will eventually equal 4, but not always.
Basically, grade schoolers.

Brave and the Bold? LOL NOT!!

Know it's totally not the answer either, but Swamp Thing?

Countdown.

No, wait, that book was a horror the entire run.

Marvelman.

No, wait, that book was just stealing DC intellectual property.

Angel Love!

You didn't even mention the golden age run of Captain America. I know, not a DC title, but you were tossing some non-DC stuff out, I expected it.

Wouldn't challengers of the well-known refuse to drink water? And state that the Earth is flat? and say that 2+2= Purple people eaters? After all, they're challenging the known, not conforming to it.

Who are you? Bendis?

Can we get back to the question at hand, guys? I wonder where this thread went astray. Has no one any more guesses at this?

(There's a clue in there, somewhere)

ugh subtle clues... it probably has to deal with astray...

No, but when I killed Bendis and ate his heart I gained his powers and strength.

Custom Creator, the thread went astray when JTR decided to post in it. Years ago. Was that a new question?

Wait, there's a clue in your post? Time to analyze it.

The Question? The Incredible Hand-Man? Krypto: Tails of a Stray Dog? Guy Gardner? The Adventures of Clock King and Hellhound?

I really don't have a clue.

Repped for truth!

I also rep you for that, but only as a partial truth. This particular thread hasn't been around for all that long.
You must be thinking of another, now locked, trivia thread.
