Appearances as a character
Atlantis: Subterranean Tours
In this guidebook to the city of Atlantis set after the film, Edgar Rice Burroughs is mentioned as a regular visitor to the city in trips conducted in secret by Whitmore Industries. He and his work have apparently become popular enough in the city that one Atlantean decided to name his Bed and Breakfast Inn the "Burroughs House", which itself has become a regular haunt of fellow science fiction author H.G. Wells.
Edgar Rice Burroughs (referred to as Ed) appears in the clip-show episode "Tarzan and the Mysterious Visitor". After the success of "A Princess of Mars", his publisher starts wondering if he's got a new story in mind. Taking inspirations from a news article on the mysterious ape-man Tarzan, Burroughs begins researching Tarzan and eventually makes his way to Tarzan's jungle and getting a proper insight into Tarzan and Jane from the people themselves.
Following the preface of the original "A Princess of Mars" story, a young Edgar Rice Burroughs is invited to his uncle John Carter's mansion to collect his inheritance in light of his supposed death. He is put in charge of the estate and is the sole person that is allowed to look at his diary, which contains the story of how Carter found his way to Barsoom. As the story wraps up, we discover that John faked his death, using his "death" and his nephew's arrival to bait the Therns that were on his trail. After killing the Thern, retrieving a medallion and planning on returning to Barsoom, Carter instructs him to stay in the Mansion and make sure the "tomb" containing his Earth body stays undisturbed while he returns to his new home. He also suggests to Edgar to "take up a cause or write a book".
- Edgar Rice Burroughs' appearance in The Legend of Tarzan, as well as his role in the episode he appeared in, are very similar to what happened in the Little Mermaid episode "Metal Fish".
