Sentinel One is the alien artificial intelligence that banded the Space Sentinels together. His maintenance operator is M.O.


Many centuries ago, Sentinel One carefully selected three young Earthlings and transported them from Earth to his planet. He then conferred upon them astounding powers, and eternal youth, then returned them home. Their mission: to watch over the human race, helping the good in it to survive and flourish. Working with Sentinel One, and his maintenance robot, the teenage guardians formed a team of Superheros called: The Space Sentinels.
