 Played by Matt Wolf and Julia Dalkin, Nebulous's parents appear only in flashbacks (although a shape-shifting alien recently posed as Nebulous's father while trying to escape a prison ship); in each episode Nebulous has a flashback to his childhood, in which his parents wanted him to become a clown and ignored such major scientific discoveries as his cure for blindness.Nebulous commonly awakes from these flashbacks saying "I shall not clown".To date, only Nebulous's former fiancée Erica Flazenby has demonstrated an awareness that Nebulous has these flashbacks, as he commonly attempts to pass them off with such comments as "Haven't you ever seen a man collapse before?"
