Space Sentinels

The Space Sentinels were young Earthlings, selected from their native lands transported Sentinel One's faraway world. While there, they were granted astounding powers, and eternal youth, then returned to Earth. Their mission: to watch over the human race, helping the good in it to survive and flourish. In the course of history, their names have become legend:
 * Hercules, empowered with the strength of a hundred men.
