The Thundermans are a family with superpowers who try to live normal lives in the fictional town of Hiddenville. Phoebe dreams of being a superhero and using her powers for good, while her twin brother Max wants to be the next big supervillain and use his powers for evil. Parents Hank and Barb attempt to live normal lives and not use their superpowers – albeit not very successfully – while Nora and Billy enjoy using theirs whenever possible. A former supervillain named Dr. Colosso has been transmogrified into a rabbit and lives in Max's lair in the basement, offering him advice on becoming a villain.
