Marvello

Dr. Marvello was a circus impresario. His troupe included Madame Fenestra, Nubu, Vicho, and the Cosmic Monster. When he realized that Will Robinson could materialize objects from his mind (with the assistance of Fenestra) he attempted to kidnap him and make him part of his circus. With Dr. Smith's duplicity, he almost succeeded, but when he saw Will's terrible sorrow at leaving his family, he relented and released the boy.
