Unlike StarBeam, Boost lacks natural superpowers, including super strength and flight, and instead uses a menagerie of high-tech gadgets and inventions to assist any way he can. Henry is relatively more scientific and down to earth than Zoey, but he does enjoy much of the same activities that she likes. Henry is the son of Mayor Blumenshine, who is unaware of his superhero identity as much as Zoey's. Henry Blumenshine/Boost: The secondary main character and Zoey’s best friend.StarBeam's suit has also changed appearances depending on the mission, from manifesting as a spacesuit to giving her a mermaid tail for underwater missions. StarBeam's powers are bubble-based, though she also has super breath in addition to flight, super strength, and super speed. Typically energetic and strong-willed, Zoey is very playful and excitable, though she doesn't like snails due to their slow and slimy nature. These individuals include her "Gramps" non-superpower grandfather her closest friend, Henry, a "Boost" superhero who invents devices that strengthen his superhero abilities and a friend who gives moral encouragement, their seagull sidekick, "Kipper." Gramps, Boost, and Kipper, together, always assist Zoey to save the day. Only a few people are aware of her hidden existence in Zoey's world.

Zoey inherited her superpowers from her superhero mother, WonderBeam, and follows the theme of family superheroes. With her catchphrase, "It's time to shine!" Zoey turns into StarBeam.

StarBeam, a superhero with unusual powers, including super-speed, super-strength, flight, high-velocity wind breathing, and the power to build force fields with bubbles, is Zoey's alter-ego. The show is based on Zoey, a girl in second grade.
