The Phantom vs. the Super-Friends

"The Phantom vs. the Super-Friends" from Super Friends vol.1 #6 (DC, 1977) by E. Nelson Bridwell, Ramona Fradon and Bob Smith

Ok, Menagerie Man isn't the Phantom. He's the Phantom during Movember, slumming it in the DCU. Well, the almost-DCU since Super-Friends was not technically part of DC continuity. But if you're looking for light-hearted fun, or perhaps back stories for Wendy, Marvin and Wonder Dog, or a secret identity for the Wonder Twins, then you've got to read these books (I think most if not all have been collected). Am I right in thinking the ethnic heroes introduced on the show (Apache Chief, Samurai, El Dorado, etc.) didn't appear in the comic? Or do I only think that because the book introduced a large ethnic cast as the Global Guardians to - I thought - compensate. Many of THOSE guys did go on to have a big impact on the post-Crisis DCU, which puts Super-Friends' canonicity in question.
