I remember there was a show called "
Fantastic Max" which ran back in 1988 to 1990 that featured the main charcter, Max, a diapered, magical space baby (Toddler) that went on outlandish adventures in outer space with his toy friends AB the robot (Yes, what a strange coincidence that the word "AB" is mentioned on a site like this! For an even more odd coincidence, see the last picture below!) and FX which he both brought to life with magic. The opening song whimsically emphasizes the importance of Max's diaper "... Well, here comes Max and his funtime heroes. It's victory again. They owe it all to that four ply diaper and that safety pin. Fantastic Max!" It was one of the shows that I watched periodically (I didn't catch all of the episodes) which aired prior to the shows that I really wanted to watch on the same day, Sunday morning, like Paw Paw Bears and Galtar. It was okay but I wouldn't really call it my favorite cartoon where the character(s) wear diapers (I can think of other characters like
Nibbles, Jerry Mouse's little nephew who was featured on a few Tom & Jerry MGM animated shorts or
Hugs and Tugs from The Care Bears being cuter but to have a diapered character featured as one of the main characters on an entire series [
Muppet Babies also comes to mind] is rare).
The series featured famous voice talents like Nancy Cartwright (She is best known as the voice of Bart Simpson) and Rene Auberjonois (He is best know as the screen actor who played Odo on Star Trek DS9) as well as other famous voice actors in various episodes like Lorezo Music (Best known as the voice of Garfield the cat, Tummi Gummi and Dr. Peter Venkman [in the first two seasons of "The Real Ghost Busters"]) and Russi Taylor who is best known as the official voice of Minnie Mouse for every animated feature film, cartoon series or TV advertisment that features the Disney character, since she took up the mantle in 1986 (See video featuring some of the many roles she voiced [She was also in an MLP movie] ->
