Jr. SuperFriends

Junior Superfriends Wendy & Marvin made their debut in 1973 in the first season of Superfriends. Wendy was practical and intelligent while Marvin was well-meaning, but prone to falling into trouble. Accompanied by Wonder Dog, the super-heroes-in-training worked with the Superfriends in an effort to become heroes in their own right.

Junior Superfriends Wendy and Marvin were later replaced in the latter 70’s with Zan and Jayna, two shape shifting twins from the planet Exxor. It took over 30 years for Wendy & Marvin to cross over into DC comic book continuity; In 2006, Wendy and Marvin became caretakers of Titans Tower in Teen Titans (third series) #34.
