The All Star Teen Sentinels was founded by Kid-Olympus after the passing of his grandfather, a former member of the Sentinels of Liberty, Mr. Olympus. There were many other groups in Paragon, but what about the new, young heroes? With that in mind, he decided to begin a new group of Sentinels, featuring future heroes who would  shape the world in a better light. Into something his grandfather would be proud of.
