In this vibrant animated series, a 13-year-old super-genius named Lunella Lafayette (voiced by Diamond White) balances the challenges of middle school life with her secret identity as the crime-fighting Moon Girl. When she accidentally transports a time-traveling T-Rex from the prehistoric past into present-day New York City, she gains an unlikely partner in Devil Dinosaur, a gigantic red Tyrannosaurus with a heart of gold. Together, the duo uses Lunella’s incredible inventions and Devil Dinosaur’s brute strength to protect their Lower East Side neighborhood from a rogues’ gallery of villains, including the scheming The Beyonder and various other threats. The series blends superhero action with coming-of-age comedy, exploring themes of friendship, family, and self-acceptance. With Lunella’s quick wit and Devil Dinosaur’s loyal, often clumsy, companionship, each episode delivers a mix of heartfelt moments and high-energy adventures. The show also features Lunella’s supportive family, including her overprotective grandfather (voiced by Laurence Fishburne), and her best friend Casey (voiced by Libe Barer), who helps keep her secret safe.
