Wonder Dog is a fictional canine superhero from the original Super Friends] television series. The character appeared in both the animated series, as well as the comic book of the same name, but was not incorporated into the DC Universe until 2008.


Super Friends TV series

In the Super Friends animated series, Wonder Dog is portrayed as the pet/sidekick of Wendy and Marvin. He appears in all 16 episodes of the original television series voiced by Frank Welker.

Super Friends comics

Wendy, Marvin and Wonder Dog were first introduced in DC Comics with the January 1976 tabloid comic Limited Collectors' Edition presents: Super Friends #C-41, in which the newcomers are welcomed to the Hall of Justice to meet the entire Justice League of America, including characters who didn't appear on the show. Their story was mostly a frame to bookend reprints of older Justice League comics, but each character got their own spotlight. Superman tells Wonder Dog about Krypto, the Dog of Steel, to reassure him (and the readers) that there's a precedent for canine superheroes adventuring with the Justice League.

Wendy, Marvin and Wonder Dog then appeared in the first nine issues of the Super Friends comic book series (November 1976 to December 1977). In issue #7 (Oct 1977), their on-screen replacements, the Wonder Twins, were introduced in a story called "The Warning of the Wonder Twins!" The cover showed the new characters literally pushing the old trio to the side, shouting, "Your time is past, kids -- this is a job for the new Super-Friends!" The three-part adventure ended in issue #9, with Wendy, Marvin and Wonder Dog retiring from the team to go to college, as the Wonder Twins are accepted as new members of the team.

Modern DC Comics

Wonder Dog makes his first appearance in the mainstream DC Universe in Teen Titans. He appears to be just a stray dog that finds his way to Titans Tower, and is named Wonder Dog by Miss Martian. Wonder Dog soon transforms into a gigantic dog beast, kills Marvin and viciously attacks Wendy, leaving her paralyzed. Wonder Dog was a hellhound used by Ares' son, King Lycus, whose goal is to destroy Wonder Girl. With every innocent death, Wonder Dog grows stronger; the Titans soon destroy him.

In 2016, another version of Wonder Dog appeared in the Scooby-Doo Team-Up comic book, in issue number eighteen.
