The Blue Falcon and Dynomutt the Dog Wonder are parodies of Batman and Robin the Boy Wonder. After the Super Friends (1973) era, Batman and most other DC Universe animation rights had passed from Hanna-Barbera to Warner Brothers. In the late 1990s, Warner Brothers subsumed Hanna-Barbera, reuniting the franchises, and making Blue Falcon and Dynomutt largely redundant. Nevertheless, they continue to appear in nostalgic cameos every few years in the Hanna-Barbera-verse.
Although the main character's is Dynomutt, and Dog Wonder is his description, in most episodes he is only ever called Dog Wonder. The name Dynomutt is spoken in the series, but only sparingly.
As with most animated superheroes of the 1970s, Blue Falcon and Dynomutt are not given an origin story.
The series' Injustice League of America predates the DC Comics' group by nearly a decade.
