The Original "Hero-Theme" was hummed by S.A. Nathe, with "drums" played on a Tissue Box. The theme was replaced by a NEW Musical version(in Episode 13) composed by Julian Chavez, the voice of "Frostbite" in Season 2 of the Series. The most-recent theme(from Episode 25) was also composed by Julian Chavez, under his "Bluewind Studios" label.
This series was the first produced by Elemental Comics Brand.
The original backstory for "Hero-Man" was based "Wii-Pals Cartoon Show". Originally he was the alter-ego of "Phil", up through the Season 1 Finale/"Movie" episode, and through part of Season 2. With the creation and inclusion of "Angel Stargazer/Firegazer", the series' origin was re-written/adapted. A new backstory was then written in the "Hero-Man Adventures" Prequel Comic Book series, telling the new origin of Hero-Man, now a 20-something tech-loving Hammond Magnus, who earned his "powers" from an alien Energy Cube he discovered.
Creator S.A. Nathe did most of the 1st Season voices.
In 1st season, there were several references to both "Wii-Pals Cartoon Show"(as HM was a spin-off series), as well as a few Nintendo video games. The last episode with such references were in the "HERO-MAN the Movie" episode.
