One would expect the 200th issue of WORLD'S FINEST COMICS to feature a Superman and Batman team-up. But not so.
It did come close to that by having the Man of Steel and the Teen Wonder--two-thirds of the World's Finest Trio--and a flashback to Dick's origin story does feature the World's Greatest Detective.
As well, there's a special text page where Superman, Batman and Robin discuss "200 Issues of the World's Finest Comics."
The Caped Crusader made a belated visit to the comic book that used to be his home, two issues late for the party, in WORLD'S FINEST COMICS 202 (May 1971).
This was the issue where Superman retired his robots, on account of pollution. One malfunctioning robot happens to survive the recall, but that's not the source of all the trouble. Malis--the "Tomb-Thing"--is an alien robot that radiates red sun energy. Entombed for eons somewhere in the Middle-East by unknown aliens, when the mechanical mummy is released, it's nearly curtains for the World's Finest Friends.
