who speak of legends of Superman trying and failing to stop the Great Disaster. The story leaves it ambiguous whether the legends are true, although Kamandi believes Superman was real, and whether the costume is indeed Superman's. Various non-Kirby stories tie the series more explicitly to the DC Universe. Kamandi met Batman in The Brave and the Bold #120 (July 1975) and #157 (December 1979). Superman #295 (January 1976) establishes that the costume seen in issue #29 was indeed Superman's, and that Earth A.D. is an alternate future for Earth-One, distinct from that of the Legion of Super-Heroes. Issues #49–50 of the series establish that Kamandi's grandfather was the elderly Buddy Blank, hero of the OMAC series, and features a brief return of OMAC's satellite ally, Brother Eye. Kirby's Kamandi story in Cancelled Comic Cavalcade #2 guest stars The Sandman and establishes that Kamandi is Jed Walker. The 1975–1977 Hercules Unbound series and the OMAC backup stories in Kamandi and The Warlord tie OMAC to both the storyline of Hercules Unbound and to the Atomic Knights, indicating that the Great Disaster was the atomic war of 1986 that precipitated the events of the latter.

In the wake of the Crisis on Infinite Earths, the Great Disaster did not occur, and the boy who would have become Kamandi instead became Tommy Tomorrow. Revival In the aftermath of the Infinite Crisis limited series, a bunker named Command D has been built under the ruins of the city of Blüdhaven. In early 2007, DC Nation house ads showed a partial picture of Darkseid and mention a "Great Disaster". Additional DC promotional art for the series Countdown show the Statue of Liberty in ruins, similar to Kamandi #1. Dan DiDio later revealed that the Statue's appearance in that teaser ad was a reference to the Sinestro Corps War. Throughout 2007, DC Comics contained continual references to a coming Great Disaster. In Countdown #31, Buddy Blank and his unnamed blond grandson are introduced into the storyline. As of Countdown #6, The Great Disaster is in
