Disney's Hercules is a spin-off of the 1997 theatrically released
animated film of the same name (Hercules) and is based on his
teen-aged adventures.
Hercules features events which occur midway through the actual
film (sometimes called a "midquel"), during his years in training
on the Isle of Idra under the tutelage of Philoctetes (Phil) the
Satyr.
Many of the Olympian Gods and Goddesses only glimpsed during the
film pay visit to the young hero-to-be and help or hinder him in
his adventures.
However, the series ignores a certain fact about the movie; Hades
believed that Hercules was dead throughout his first 18 years of
his life, but they have many interactions during this time
