The wikipedia article cites [http://www.toonopedia.com/kamandi.htm Markstein, Don (2010). "Kamandi, The Last Boy On Earth"]. Don Markstein's Toonopedia which appeared back in 2003.

"Along the way, Kamandi's Great Disaster was tied in with the nuclear war that had spawned The Atomic Knights (tho apparently there was more to it than just a nuclear war). This war had been established as having occurred in 1986, so as that year approached, the "Great Disaster" scenario (which by that time, several series had used) became less plausible."

Another article on the internet states "In 1975, the Hercules Unbound series started pulling all sorts of old post-apocalyptic DC stories together, using as an unifying event the Great Disaster. This tied, among others, OMAC, Kamandi, Hercules and the Atomic Knights."

Nerds on earth provides more evidence pointing to this being true.

So there was a lot more then just one character making a cameo that tied Kamandi, Kamandi, Hercules and the Atomic Knights together.
