Space Sentinels (originally titled The Young Sentinels and renamed midway through its only season) is a Saturday morning animated series produced by Filmation which debuted on the American NBC network on September 10, 1977 and ran for thirteen half-hour episodes.
- Hercules: blonde-haired and blue-eyed Hercules possesses superhuman strength. He was voiced by George DiCenzo, who also voiced Sentinel One and later reprised the role of Hercules in The Freedom Force animated series.
- Mercury: Mercury's power is the ability to run and fly at up to the speed of light. Mercury is of Asian ancestry. He was voiced by Asian American actor character actor Evan C. Kim (who is credited here as simply "Evan Kim").
- Astrea: Astrea can morph into nearly any living animal. She, along with the Super Friends' Black Vulcan and Cyborg, was one of the very few African American superheroes of the era. She was voiced by African American character actress Dee Timberlake.
- Mo (Maintenance Operator): Sentinel One's robot assistant, voiced by Filmation co-founder and executive producer Lou Scheimer.
Antagonists included the "sinister" villain Morpheus, the Sentinels' sworn enemy; he was also an Earthling given powers in the same manner as Hercules, Mercury, and Astrea, but far earlier. Those who had given Morpheus his powers had erred by giving him a variety rather than one specific power; he had rebelled and turned to evil. Secondary antagonists include the Sorceress, as well as Anubis, modeled after the Egyptian god of the same name.
