They help Tegan battle her inner demons as personified by the Mara, and meet the Doctor's old friend and ally Brigadier Lethbridge-Stewart. Nyssa and the Doctor are reunited with Tegan while battling against Omega in Amsterdam and on Gallifrey. Nyssa travels alone with the Doctor for an unspecified period of time when the Doctor leaves Tegan at Heathrow. During this adventure, Nyssa also displays a previously unseen psychic ability when she is contacted by the Xeraphin. When confronted by an illusion of Adric created by the Master shortly afterwards, both Nyssa and Tegan are initially taken aback, until they see through the deception when Nyssa sees Adric is still wearing his now-destroyed badge. She also encounters a race of androids and their insane ruler, helps foil the genocidal plans of a wounded Terileptil and incidentally start the Great Fire of London, and discovers her remarkable resemblance to Ann Talbot.Īdric's death while battling the Cybermen affects the TARDIS crew deeply. She subsequently joins Adric and Tegan Jovanka as a companion and member of the TARDIS crew, and witnesses the Fourth Doctor's regeneration into the Fifth.ĭuring her journeys with Tegan and Adric aboard the TARDIS, Nyssa finds herself trapped in a mathematical equation by the Master – whom she hates as he is, of course, now using "that face" (her father's). After being freed from his control, she is brought to Logopolis by the Watcher and discovers that Traken has been destroyed as a side effect of the Master's tampering with the Logopolitan's formulae. She aids the Doctor and Adric when the Master wrests control of the Keepership by first manipulating and then murdering her stepmother, but is herself hypnotised and kidnapped by the Master after he takes control of her father's body. Nyssa is an aristocratic native of Traken, the daughter of Tremas (a consul of the Traken Union) and stepdaughter of Kassia. Nyssa was the Doctors comapnion from The Keeper of Traken to Terminus.
