Change #1.... Hercules was the son of Zeus and Hera, they were the perfect family. Unlike the mythological version when Zeus cheats on Hera.
Change #2.... Hera isn't shown negative and a villain as a character. Hera had a nice family and cared for them.
Change #3.... Hades was the villain in the Disney movie, and tried to hurt the hero in someway like every villain does. Like always the villain gets defeated and the hero is here to save the day. He most likely saves the damsel in distress or any other character that is being harmed.
