Editing Captain Future (section)

== Characters ==
; Captain Future: Tall, athletic and handsome, with red hair, Captain Future was born on the Moon as Curtis Newton. After the death of his parents, he was trained by Professor Simon, Otho and Grag in all scientific and athletic pursuits necessary to fight crime and injustice across the Solar System.
; Prof. Simon Wright: A human brain [[Isolated brain#In fiction|living in a transparent, nuclear-powered life support case]], with tentacle-mounted optics. He is Captain Future's mentor and chief consultant in scientific matters.
; Grag and Otho: Grag is a seven-foot-tall metallic robot. Otho is a white-skinned android. Both were created by Roger Newton with [[artificial intelligence]] and human emotions to be friends and helpers to mankind. Grag and Otho have a friendly rivalry. Grag is big and strong, but not very bright, while Otho is quick-witted, agile, and (with the aid of a special chemical) able to alter his physical appearance.
; Eek and Oog: Grag and Otho's pets, respectively. Eek is a "moonpup", a canine creature which does not need air to survive and consumes soft metals for food. Oog is an amorphous being called a mimic, an artificially created pet that can change its shape as Otho does. Both are telepathic, and are attached to their respective master.
; Joan Randall: A beautiful female agent of the Planetary Police on Earth. She has brunette hair (or blonde hair in the anime adaptation). She shares a mutual romantic attraction with Curtis, but their respective duties prevent them from taking their relationship further.
; Marshall Ezra Gurney: A high-ranking veteran officer in the Planetary Police.
; Ul Quorn: Son of Victor Corvo, the man who murdered Captain Future's parents. A scientific genius, he has chosen to use his intellect for evil purposes.
; Johnny Kirk: An orphan boy and a dedicated fan of the Futuremen. During his debut appearance in "The Magician of Mars", he impresses Captain Future with his determination to become one of his crew, and is later entrusted to Joan and the Planetary Police to be trained as a future crew-member. He has an expanded role and different name ('''Ken Scott''') in the anime.
