So, today, in fairness, a quick little look at the elder statesman of crime, the Golden Age Joker!
BeginningsCatwoman), and continued to menace the Dynamic Duo for well over a decade.
Earth-1 Two-Face (as evidenced by the fact that Harvey was remade into Two-Face in this issue, and an appearance in Superman Family stated that the Earth-2 Harvey Dent had never had his surgery undone).
...where a semi-retired Batman and Robin, the ex-Boy Wonder worked with the JLA, JSA and Squadron of Justice (heroes of Earth-S which didn't belong to the Marvel Family like Ibis the Invincible, Spy Smasher, Bulletman and Bulletgirl) against villains united by Captain Marvel's old foe, King Kull, such as Dr. Light, the Shade and the Weeper.
...other than that he was an age appropriate analog for the older Batman of the Justice Society of America (though he did have a little more of Dick Sprang look to him, at least on the inside of the book, than the current, more Jim Aparo, thin look which was on the cover by Ernie Chan and Frank Giacoia).
He barely even appeared in the issue...
....just a mild distraction for a couple of pages, as he was working with the Weeper.
Joker Vs. The Batman's Daughter
The Joker did return, to face Batman's daughter, the Huntress (Helena Wayne), in a run of her back up stories from Wonder Woman #280 to #283 (June to September, 1981, in stories by Paul Levitz, Joe Staton and Steve Mitchell).
But, who was that "Batman"? Here's a hint (and he appeared in the next issue in his usual identity).
The Joker, ever the instigator, is the roommate of the mostly comatose since the 1950s Brimstone (Nicholas Lucien), a villain who faced the Earth-2 Batman and Robin in a cleverly made flashback tale (though he felt much more like a 1960s TV Batman villain, with a flame motif), but fell into a coma after his first battle after being battered around by Batman, only waking up in prison after the Earth-2 Batman was dead.
team-up of the Earth-1 and Earth-2 Batmen.
This also allowed the Joker a bit of a legacy, inspiring an evil which could even cross Earths, all before the Crisis On Infinite Earths!
