Batman #511 1994

Batman #511, published by DC in September 1994, is a pivotal Zero Hour tie-in issue. The story, "The Night Before Zero," sees Batgirl mysteriously reappear in Gotham City, years after Barbara Gordon's paralysis, but in an altered reality where Commissioner Gordon died and Harvey Dent leads the GCPD. Batman and Robin grapple with these shifting realities and the Joker's rampage, prompting Batman to seek answers from Oracle and Superman about the unfolding temporal anomalies. This issue is notable for its direct connection to the universe-altering Zero Hour event and its exploration of alternate timelines.
