The show is based on the action figures and playsets of the Rescue Heroes toy line by Fisher-Price. The action figures each had a mounting bracket on their back that allowed various rescue tools and equipment, such as jackhammers, cutting tools, and various firefighting equipment, to be affixed to the figure. Many characters were re-released with different appearances and new tools.
The heroes' last names, reflect their occupation (e.g. 'Billy Blazes' deals with fires, 'Ariel Flyer' flies helicopters).
