Wendy Harris and Marvin White are fictional characters, two teen-aged sidekick of the Super Friends. Along with Marvin's pet dog Wonderdog, they first appeared in the 1973 Super Friends cartoon. Because of the success of the Super Friends cartoon, a Super Friends comic book was also created, in which Wendy and Marvin made their first comics appearance.
The duo has been re-introduced in the Teen Titans comic book as the caretakers of Titans Tower.
Wendy Harris and Marvin White are two sidekicks who were created in an era in which many cartoons featured main characters with sidekicks who were supposed to serve two purposes: comic relief and viewer identification. In the cartoon, the reason for Wendy and Marvin hanging around with the Super Friends was never really explained. In the comics, some additional information was given. Wendy is the niece of Harvey Harris, a detective who once trained Batman when he was still a teenager. It was postulated in an editorial column that she may have been the Earth-One version of Wendi Harris Tyler, wife of the first Hourman. Marvin (who was given the last name of White in the comics) was the son of Diana Prince, the nurse whose name Wonder Woman took when she came to Man's World, and her husband Dan White. Thus, Marvin had a sort of familial connection to the Super Friends. The Super Friends were designed to help teach young crimefighters how to be superheroes. While Wendy never wore any special costume, Marvin was always dressed with a cape and a big letter "M" on his chest.
E. Nelson Bridwell, the writer on Super Friends, shed some light on the characters' origins in Super Friends #1 (Nov. 1976):
