It’s my understanding that the pre-crisis Earth-2 Batman died. Was the corresponding Joker still alive? Did Earth-2 Joker die before being retconned out of existence by the Crisis On Infinite Earths?
He definitely outlived Batman. In The Brave and the Bold # 200, the story is an “old foe” (newly invented for that very issue) of the Earth-2 Batman wakes up from a decades-long coma to discover that Batman died at the hands of another, and one of the people he speaks to is an aged Earth-2 Joker. (After leaving the hospital, he mentally takes over the body of his Earth-1 counterpart, who is an upstanding citizen, in order to get his revenge-by-proxy on Earth-1 Batman.)
I guess the editors of DC’s wiki overlooked that scene.
I guess I was unclear. When I said they didn’t know, it was only about when the Earth-2 Joker died, not whether he died before or after Earth-2 Batman. They definitely have him dying long after Bat-2.
The DC Wikia page (which I assume is edited by obsessed nerds even more extreme than the ones here) says the Earth-2 Joker’s was never depicted or referenced, leaving the assumption that he disappeared along with Earth-2 during the Crisis.
It does not, however, mention his cameo in Brave and Bold#200, and I’m thinking about adding it.
