List of minor characters in the Firefly universe

This article is about minor characters in the television series Firefly, (defined as any characters appearing in the show, or the follow-up movie Serenity, that aren't core cast members - the crew of the spaceship Serenity).

=Badger= One the crew's contacts on the moon-planet Persephone, Badger appeared in the pilot episode of the series, Serenity. Badger, an "honest businessman" refused to pay for cargo that he had commissioned the crew to retrieve after they were spotted by Alliance forces.

=Niska, Adelei= Adelei Niska is the crime lord of the Firefly universe. Thoroughly ruthless in his business practices, he has a reputation for exacting terrible reprisals on those that fail him - a reputation well-deserved, as Malcolm Reynolds and Wash discover in War Stories. He frequently spouts rather brutal philosophy while torturing his victims, notably that of the dictator Shan Yue.
