What about the Earths that had Superman, Wonder Woman, and The Lone Ranger (!) meeting up with The Brady Kids?
I guess "Earth-Filmation", since Filmation produced that horrible "Brady Kids" cartoon...
And did those meetings take place on the Batman & Robin Meet Scooby-Doo Earth???
Since Scooby's made by Hanna-barbera, no.
I'll assume it's "Earth-Scooby", since Scooby's world doesn't seem to have any superheroes besides Batman, Robin, Blue Falcon, and Dynomutt (or rather, no superpowered superheroes...which I guess befits Scooby Doo's cartoonish-meets-semi-realistic/mystery-focused setting...).
And upon WHICH Earth did the 1970's, non-violent, Batman cartoons (with Bat-Mite) take place???
I guess Earth-Filmation again (since Filmation made those). :-)
