The story would go on to reveal that Kamandi was somehow "the pivotal point of infinities uncountable":
The series would have gone on to show that Kamandi was a multiversal counterpart of Jed, the kid who was always hanging around with Kirby's Sandman. And heaven knows where Jack C. Harris was heading with this "pivotal point of the whole damned multiverse" business.
So, thanks for nothing, DC Implosion.
OK, this one is complicated. This story was planned for the never-published Kamandi #60 (would have been 1978). It was printed in the little-seen Cancelled Comics Cavalcade #2 (1978). As reprinted in Kamandi Challenge Special #1 (2017), where these scans were taken from. Phew!
