On Super Goat Girl's first day at her new school, she's met with stares. Laserbeam Lass, Robo Kid, and Noodle Boy don't know what to make of her--after all, what kind of a super has no swagger, and not even a cape? At recess, while the others have fun writing with lasers, doing lightning-fast math, and being super stretchy, Super Goat Girl doubts she can measure up. But when an army of evil aliens appears and ties up their teacher, Miss Damsel, it's Super Goat Girl to the rescue--the only one who can chomp through the impossibly strong rope. She's sure she'll fit in now, but the other kids just seem confused--is chewing even a superpower? So maybe she's still not the right kind of super. At lunch, she gets another chance to prove herself when a giant gorilla crashes into the cafeteria and her supersonic bleat scares him away. But is being loud a superpower?

Then the biggest test comes when the other kids accidentally create a black hole and Miss Damsel is sucked inside. This time when Super Goat Girl helps them save the day with her bravery and quick thinking, they begin to appreciate her. After all, almost every day calls for some superpowers--and they now realize that by sticking together, they'll have the best chance of taking on anything that comes their way.
