Cally is portrayed by Jan Chappell in both the television series and the Big Finish Production series.
Some confusion surrounds Cally's origins. In Time Squad she declared that she was sent from Auron to help the people of Saurian Major. In Dawn of the Gods, however, Tarrant asked her what she did to upset her people, and she admitted to being an exile in Children of Auron. CA 1 described her as a "rebel".
In Time Squad she first appeared carrying a flimsy-looking rifle (which was never seen again in future episodes), preparing for a suicide mission against the Federation communications relay station on Saurian Major. Her guerilla experience surfaced again in Duel, where she expressed approval of Blake's tactics in stalking Travis.
Known relatives: Zelda, a twin sister, who died in the destruction of the replication plant on Auron. According to Dayna, there were "plenty more like her on Auron, apparently", and the brood units seen in Children of Auron could incubate fifteen or more fetuses. Zelda acknowledged that she and Cally were from the same sibling group. In The Harvest of Kairos Cally telepathically detected images of her mother and father in Sopron: Avon told her that her parents were dead. If these were her natural parents she could not have been a clone (unless conventionally fertilised embryos were also cloned), and if she had a dozen or more clone-sisters they were never detailed.
Significant brawls: In unarmed combat she had a mixed record, losing to Blake in Time Squad, being knocked unconscious by the substitute Avalon in Project Avalon, by Gan in Breakdown, overpowered by Ensor Jr in Deliverance, and Mori's troopers in Volcano. She was overpowered by Sherm whilst grappling with Bayban. She had to be rescued by Tarrant from a link on Terminal. She also needed to be restrained by Blake in The Web. On the other hand, she incapacitated a trooper in Seek-Locate-Destroy and another in Bounty, Molok in Hostage, another trooper in Children of Auron, and one of Sula's rebels in Rumours of Death.
She seemed quite prepared to kill Travis in Seek-Locate-Destroy, but was restrained from doing so by Blake. Her first actual kill came as late as City at the Edge of the World, where she shot two of Bayban's men, one of them being Sherm. She also offered to kill Bayban. She later shot a link on Terminal. She also fired on and destroyed a gunship from Freedom City in Shadow after issuing two warnings. In Shadow with Moon Discs Captured by: Travis in Seek-Locate-Destroy, by the Amagons (along with the rest of the crew) in Bounty, by the Altas (again with everyone else) in Redemption, by the Federation in Horizon, by Molok in Hostage, by the Chengans in Powerplay, by Mori in Volcano, the Thaarn in Dawn of the Gods, by Servalan in Children of Auron, by the Ultra in Ultraworld, and by Servalan again (along with everyone else) in Terminal. Only in Dawn of the Gods did she manage to escape entirely unaided, though in Hostage she and Jenna disposed of Molok and kept the Liberator out of Travis" hands.
With help from the moon discs she saved the Liberator from destruction in Shadow. She also attempted to rescue the rest of the crew (bar Avon) in Horizon. She probably saved Vila's life in Dawn of the Gods by telepathically telling him to run from the approaching vehicle, and later allowed the entire crew to escape by persuading the Thaarn to switch off the energy isolaters. She also rescued Avon and Vila in Sarcophagus.
Significant injuries: Cally sustained serious burns to her left hand in The Web, was tortured by Travis in Seek-Locate-Destroy, received a significant head injury from the android Avalon, knocked unconscious by Gan in Breakdown, suffered facial burns escaping from the stricken Liberator after the Intergalactic War, briefly contracted the disease introduced to Auron by Servalan and had her mind emptied by the Ultra (it later being restored by Tarrant).
Over the course of 37 episodes she set foot on Saurian Major, Centero, UP-Bounty, Aristo, Space World, Saurian Minor, Zonda, Horizon, UP-Gambit, The Goliath System, The Derelict Zone, Straxis, Horst Minor, The Cage, Star One, Megiddo, Chenga, Obsidian, Destiny, Cortol Four, Crandor, Kairos, Keezarn, Auron, Earth, Shoren, Space Station Arcadia, The Scimitar, Solace, Carwen, Laruedon, Appallon Five, Ultraworld and Terminal - a total of just 18 planets/space stations. She remained aboard the Liberator in no less than 16 episodes.
Her first words ("Who are you") were telepathically transmitted to Blake, but she used her talent rather infrequently. See TELEPATHY for more details. Her last recorded spoken words were "She's beginning to go", referring to Liberator's breaking up above Terminal. Her final word was "Blake", telepathically screamed as the underground complex on Terminal blew up.
In Dawn of the Gods, She helped get the crew out by telling Tharn to switch off the energy isolaters
In The Harvest of Kairos She was subjected to mental take-over no less than five times, by the Lost in The Web, by the Darkness in Shadow, by the Thaarn in Dawn of the Gods, by an undead alien in Sarcophagus and by the Ultra in Ultraworld. She also detected the malign nature of the alien pathogens carried by Wanderer K47 in Killer. She suggested that the Lost were able to take control of her because she was unprepared for them, and the same is possibly true of the other occasions when malign influences seized control of her mind.
In Time Squad she stated that her work was in communications, and she managed to modify the teleport operating frequency fairly quickly in Moloch. Her general technical ability was not inconsiderable. She also appeared to have some medical skill, diagnosing the radiation sickness affecting Avon, Jenna, Vila and Gan in Orac and recognising the symptoms of fatigue shock in Horizon. In Voice from the Past Avon, Blake and Jenna were seen following exercises she had recommended, Cally herself sitting in a lotus position. Avon was not overly-convinced of their worth.
She was on various occasions referred to as an alien and a human (see AURON). The loneliness of a single telepath was referred to in Time Squad, when she cursed Blake with "May you die alone and silent", and in Mission to Destiny when she telepathically cried "Alone!" when roused from the effects of the sono vapour. Much was also made of this by the Thaarn - who claimed to share this loneliness, and offered to make her "queen of a thousand worlds" - and the undead alien in Sarcophagus, who believed that Cally could have no true loyalties to any non-telepath (Avon proved her wrong).
Cally's loyalty to Blake was apparently unflinching, although she did question his fanaticism in Star One and Blake accused her of colluding with Avon in Voice from the Past. In Sarcophagus she was quick to let go of Vila's hand having rescued him, but openly expressed delight at seeing him return in City at the Edge of the World. Her initial relationship with Jenna was rather bristly. Relations between Cally and Avon were ambiguous (and the subject of considerable fan discussion): they worked well as a team in City at the Edge of the World, but she lost no opportunity in putting him down in Children of Auron (admittedly, this was just after he had criticised Auron's isolationist policy). In Sarcophagus Avon relied on Cally's loyalty to the rest of the crew and himself in particular to defeat the undead alien. In Moloch She stayed with Liberator after the Intergalactic War, despite the lack of overtly dissident action taken by the crew in this period. She seemed to be left out of early discussions on Tarrant's plan to raid the kairopan transporter and disapproved of Avon's intent to execute Shrinker. In Sarcophagus she was seen sketching, suggesting a possible artistic bent, but no meaningful indication of any talent or ongoing interest was given. Last seen in Terminal,when the Liberator was destroyed. Avon reported her dead in Rescue, although her body was never seen.
Cally also has the distinction of having the most drastic haircut ever undertaken by a member of the crew, at some point between Orac and Redemption.
