Editing Blake's 7 (section)

=== Regular characters ===
* [[Roj Blake]], played by [[Gareth Thomas (actor)|Gareth Thomas]] (leader of the crew in series 1–2, guest appearances in series 3–4). Blake is a long-term political dissident who uses the ''Liberator'' to wage war on the Federation. He is passionately opposed to the Federation's injustice and corruption, and he is prepared to accept loss of life in pursuit of its destruction. He thinks nothing of placing himself in danger to protect his crew or advance his cause. Although Blake is respected by many of his crew members, Avon accuses him of fanaticism and recklessness.<ref name="B7 Programme Guide/OwnWords">{{Cite book| last = Attwood| first = Tony| title = Blake's 7: The Programme Guide.| location = England| isbn = 0-426-19449-7| chapter = In Their Own Words| publisher = [[Virgin Books]]| year = 1994| pages = [https://archive.org/details/terrynationsblak00attw/page/118 118–125]| author2 = Davies, Kevin| author3 = Emery, Rob| author4 = Ophir, Jackie| chapter-url = https://archive.org/details/terrynationsblak00attw/page/118}}</ref>
* [[Kerr Avon]], played by [[Paul Darrow]] (series 1–4, leader of the crew in series 3–4). Avon is an electronics and computer expert who once attempted to steal 5 million [[Fictional currency|credits]] from the Federation banking system. He distrusts emotion, and he attempts to pursue a code based on logic and reason. This frequently causes conflict with Blake. He becomes a reluctant rebel and, at times, he seems motivated by financial gain and shows his readiness to put companions in danger in order to protect himself. He has an ambiguous and sometimes playful relationship with Servalan.<ref name="B7 Programme Guide/OwnWords"/> Avon appears in 51 of the series' 52 episodes, being absent only in the first episode, "The Way Back".
* [[Vila Restal]], played by [[Michael Keating (actor)|Michael Keating]] (series 1–4). Vila is a skilled thief, lock-picker and conjurer and is usually reluctant to risk his life. His behaviour is often cowardly and, although other crew members regard him as tiresome, he has a high IQ. He has weaknesses for alcohol and women, and apparently talks to himself at times.<ref name="B7 Programme Guide/OwnWords"/> Vila is the only character to appear in every episode of the series.
* [[Jenna Stannis]], played by [[Sally Knyvette]] (series 1–2). Jenna is a former space smuggler and skilled pilot who becomes adept at piloting ''Liberator''. She has a great deal of affection for Blake, and she is loyal to him once he gains her trust.<ref name="B7 Programme Guide"/> In earlier episodes, Jenna often maintains her opinions stubbornly.
* [[Cally (Blake's 7)|Cally]], played by [[Jan Chappell]] (series 1–3). Cally is an alien [[guerrilla fighter]] from the planet Auron. She is a [[telepath]], like all of her people, who can transmit thoughts silently to others. She later develops mind-reading, telekinesis and precognition abilities, but she is also uniquely vulnerable to telepathic control by alien forces.<ref name="B7 Programme Guide"/> Cally develops as the moral conscience of the group, especially for later episodes of series 2 and throughout series 3.
* [[Dayna Mellanby]], played by [[Josette Simon]] (series 3–4). The daughter of former dissident Hal Mellanby, Dayna is an expert in weapons technology. She is adept at designing mechanized weapons but also appreciates the nobility of what she describes as more 'primitive' combat. Brave and loyal, but at times reckless and naïve, she often successfully challenges men who are supposedly accomplished fighters.<ref name="B7 Programme Guide"/> Her vendetta against Servalan (who murdered her father) motivates her to endorse Avon's fighting of the Federation.
* [[Del Tarrant]], played by [[Steven Pacey]] (series 3–4). Tarrant is an expert pilot who trained with the Federation before beginning illegal activities. He is ruthless and charming, and he often challenges Avon's leadership. He also takes advantage of the cowardice of Vila, whom he bullies into performing his instructions.<ref name="B7 Programme Guide"/>
* [[Olag Gan]], played by [[David Jackson (British actor)|David Jackson]] (series 1–2). Having killed the Federation guard who murdered his girlfriend, Gan has been implanted with an electronic "limiter" device which prevents him from ever killing again. However, he is courageous, strong, and dedicated to Blake's cause.
* [[Soolin]], played by [[Glynis Barber]] (series 4). Soolin is an expert [[gunfighter]] whose parents were murdered when she was a child on her home planet of Gauda Prime. She joins the group after she is betrayed by her partner Dorian. No-one can match her speed at drawing a gun. Soolin's logical and cynical attitude proves an asset to her colleagues. On several occasions, her quick thinking and prescient actions save the crew from perishing, overpowering the assassin Cancer and surviving the Betafarl Conspiracy. Barber had also previously played the role of a Mutoid in series 1 (episode 9: "Project Avalon").
* [[Characters of Blake's 7#Orac|Orac]], voiced by [[Derek Farr]] (first appearance) and [[Peter Tuddenham]] (series 2–4). Orac is a super-computer capable of reading any other computer's data and built by an inventor named Ensor. It uses a component called a Tariel cell—a universal computer component—and can access information stored on any computer that uses one. It can also control other computers. Orac dislikes work that it considers unnecessary, enjoys gathering information and has delusions of grandeur.<ref name="B7 Programme Guide"/>
* [[Characters of Blake's 7#Zen|Zen]], voiced by [[Peter Tuddenham]] (series 1–3). The main computer aboard ''Liberator'', Zen controls the craft's secondary systems, including the battle and guidance computers. It is susceptible to interference from outside influences, such as Orac. It is considered a character in its own right. It is rendered nonfunctional after ''Liberator'' is damaged by corrosive fluid particles, and is destroyed with the ship.<ref name="B7 Programme Guide"/>
* [[Slave (Blake's 7)|Slave]], voiced by [[Peter Tuddenham]] (series 4). Introduced during the fourth series, Slave was built and programmed by Dorian and is the master computer of Dorian's ship, ''Scorpio''. It has a cringing personality, frequently apologetic and obsequious, and addresses Avon as 'master' and others as 'sir' or 'madam'.<ref name="B7 Programme Guide">{{Cite book
