The series stars WordGirl, a girl with superpowers whose secret identity is Becky Botsford, a student. WordGirl was born on the fictional planet Lexicon (also a term referring to the vocabulary of a language or to a dictionary) but was sent away after sneaking onto a spaceship and sleeping there when she was an infant. Captain Huggy Face, a monkey who was a pilot in the Lexicon Air Force, piloted the ship, but lost control when WordGirl awoke, and crash-landed on Earth (more specifically in Fair City), a planet that affords WordGirl her superpowers, including flight and super strength. WordGirl utilizes these powers to save her adoptive home, using her downed spacecraft as a secret base of operations.
