The series began with the main character, Prince Dex, escaping the Plague Patrol with a small group of Edenoites rebels, before leaving for Earth, the next target of his sinister uncle Count Dregon who ruled Edenoi with an iron fist after displacing Dex's grandfather King Lexian who also gave Dex the Masked Rider powers (where the powers came from is a mystery, although they have been kept for some time by Edenoi's champions). Arriving on Earth in a massive crater, Dex finds himself in the care of the Stewarts, a multiracial family consisting of a white father and adopted daughter (named Hal and Molly respectively), an Asian wife (Barbara), and their adopted African-American son (Albee). The addition of an extra Stewart was not noticed by anyone (although, according to Albee, he and Molly are adopted) in Leawood, the town where the series took place in. Dex defends the town as Masked Rider from Count Dregon and his vicious Insectovores.
