I'm in a crisis state of mind.

The Monitor helped the Jailer neutralize Superman before Crisis. How?

That was my second guess. However, Earth-2 Aquaman appeared in the issue where they had the first general meeting of the Squadron, where Liberty Belle is discussing members who couldn't attend. I believe Roy Thomas mentioned it in the letter column that this issue confirms that there was an Aquaman on Earth-2 who was a contemporary of the Squadron, which had never been made clear before.

--I think.

He didn't actually appear in that issue (#31); Liberty Belle mentioned him, and there was an illustration of him to go along with that, but he himself didn't show up.

It's funny, because Liberty Belle said that Aquaman was "difficult to contact". Doesn't look all that hard to me.

Can you be sure that the Aquaman in that picture really is the Earth-2 Aquaman?

He has yellow gloves; that's usually the difference. Like Superman's simpler S-symbol.

I find your objection specious, sir.

To claim that this illustration with word bubbles is somehow more or less "an appearance" than that illustration with word bubbles is stretching my credulity.

Would you likewise claim that the new Amazing-Man's "first appearance" did not count because it was bookended by other JSAers relating the story of how Power Girl and KC Superman went to Louisiana to recruit him?

--yours sincerely,
wyld, esq.

I submit, sir, that the real and genuine Aquaman of Earth-Two was not in that issue, merely an image of him that only the reader could "see". My question asked which Earth-Two hero did not appear with the All-Star Squadron until just before he was erased from continuity; and the real and actual Aquaman did not meet the rest of the Squadron until #59.

I accept your rationalizations, sir, though I do not wholly agree with them.

Though, it may be that such reasoned debate on the relative realness or dasein of comic book characters may be, to some degree, whistling in the dark. Mmm?

--yellow gloves, you say?

Yes, although I know he wore them in the first appearance of the JLA.

Batman...he bought it yesterday...

Zatara is currently running things in this here thread.
