Straxus was sent by the High Council to the Doctor's TARDIS. He ordered the Eighth Doctor to Lonsis in 2006 to retrieve Lucie Miller from a temporal blackspot. The Doctor agreed on the condition that Straxus fix his TARDIS. Straxus agreed and gave the Doctor a time ring for his mission. On the Doctor's return, Straxus told the Doctor why Lucie was originally taken out of her own time and sent to the Doctor. He then helped the Doctor defeat the Cybermen on Lonsis before returning to Gallifrey. (AUDIO: Human Resources)
Straxus was later sent by the Time Lords to take the Doctor back to Gallifrey, where he was to be quarantined with the rest of the Time Lords in order to prevent the resurrection of Morbius. (AUDIO: Sisters of the Flame) Straxus failed to find the Doctor in time and instead was captured by Cristophe Zarodnix and was forced to surrender his DNA in order to resurrect Morbius. Straxus was imprisoned for ten years while Morbius fed on Straxus' life energy whenever he became weak. The Doctor and Lucie came for Straxus and the Doctor sacrificed his life to save the universe from Morbius. Straxus' life energy was restored after the Time Lords corrected history. Straxus was taken back to Karn, where he offered to take Lucie home to Earth. (AUDIO: The Vengeance of Morbius)
Behind the scenes
- On the 12 July 2011 edition of The Big Finish Podcast, Nicholas Briggs revealed that the original actor hired to play Straxus had to be fired. When the original actor proved unsuitable for the role, Briggs quickly called someone he knew — Nickolas Grace — to take over. The crew became so enamoured of his performance on the audio story Human Resources that they wrote Straxus into The Vengeance of Morbius. Briggs went on to claim that this was the only time in Big Finish's Doctor Who production where an actor had to be fired for performance deficiencies.
