Stanley Stretch never knew a lot of things: he never knew superpowers ran in his blood, that his dad was a scientist secretly employed to find weaknesses of supervillains, and that his dad was suppressing Stanley's own powers. He also never knew that other superpowered teens roamed his high school hallways—including the girl of his dreams. But one epically-failed school science experiment later, Stanley's newly-discovered uncle is training him, and five other superteens, to combat the Shadow Master and his (or "its"?) gang of nefarious villains and characters from mythology and pop culture. No one would have thought that Stanley, Lucy, Eric, Tyler, Eve, and Zack would be the ones chosen for such a mission. They're in over their heads, but there's no going back now.
