Main characters
From The Firefly and Serenity Database
The following is a list of the main characters for the television series Firefly.
- Malcolm Reynolds (Nathan Fillion), Serenity's captain and former Independent sergeant in the pivotal Battle of Serenity Valley.
- Zoë Alleyne Washburne (Gina Torres), second-in-command onboard the Serenity and loyal wartime friend of Reynolds.
- Hoban "Wash" Washburne (Alan Tudyk), the pilot of Serenity and Zoë's amusingly insecure husband.
- Inara Serra (Morena Baccarin), a Companion, which is the 26th century equivalent of a courtesan. Like her Renaissance colleagues, Inara enjoys high social standing. She and Mal have a mutual love-hate relationship, with unspoken sexual tension heating many of their interactions.
- Kaylee Frye (Jewel Staite), ship's mechanic. With no formal training, she keeps the ship, Serenity, running with an intuitive mechanical talent. As a result, she's extremely sensitive to insults (or even candid observations) about the ship's appearance.
- Jayne Cobb (Adam Baldwin), crew member. He's a dull-witted, violent, and self-serving bandit that Mal bought off while in the very process of being robbed by him.
- Simon Tam (Sean Maher), a medical researcher and physician of the first caliber, on the lam after breaking his sister River out of a government research facility. His bumbling attempts to start a relationship with Kaylee lead to frustration for both as time goes on.
- River Tam (Summer Glau), a stowaway. River was a genius and child prodigy, but suffered from unspecified experimentation at the hands of Alliance doctors. As a result, she is psychotic and almost impossible to communicate with, but still undeniably brilliant.
- Derrial Book (Ron Glass), a holy man or "Shepherd". He has priority status in the Alliance, for unspecified reasons, and demonstrates a peculiar depth of knowledge about firearms and criminal activities. His full identity remains a mystery.
