'''Straxus''' was a [[Time Lord]] who acted as an agent for the [[Celestial Intervention Agency]] and [[High Council]] at different times. He was notable for interfering in his own future (at his superiors' behest) on two separate occasions.
{{Straxuses}}
'''Kotris''' was an incarnation of the [[Time Lord]] [[Straxus]] who worked with the [[Dalek]]s.
Straxus once worked for the [[Celestial Intervention Agency]]. Unbeknownst to the [[High Council]], he was instructed to gather from the [[Vess]] weapons that would allow the Time Lords to defend themselves and defeat races that posed a threat to Gallifrey. He was discovered by {{Pratt}}, who blackmailed him and the CIA by threatening to inform the High Council. In exchange for his silence, Straxus let him buy a [[conceptual bomb]] from the Vess. The Master used the device to attack the Doctor's timeline, using the bomb to erase [[the Doctor's TARDIS]] and consequently everything he had accomplished. Recognising that the loss of the Doctor from history was causing too much damage, Straxus then captured the [[Sixth Doctor]] to ask for his help in defeating the Master. Eventually, he regretted his own actions and claimed he meant to report to the High Council. His TARDIS was destroyed by the Sixth Doctor by forcing and expanding its dimensional stabilisation field, in order to let the Doctor's other incarnations land in the pocket dimension of the Vess at the same time. Although the first three Doctors were only able to partially materialise, this was enough for the other Doctors to work out what the Master had done and undo his attack, essentially erasing the whole crisis from existence.

[[File:StraxusLightAtTheEnd.jpg|thumb|left|A young Straxus, working for the CIA. ([[AUDIO]]: ''[[The Light at the End (audio story)|The Light at the End]]'')]]
Straxus became fed up with the morally questionable actions of himself and his people, and allied himself with the [[Dalek Time Controller]]. The Dalek Time Controller helped him rewrite his [[biodata]] to remove his [[Time Lord]] heritage, so that when they retroactively destroyed the Time Lords the new Straxus — now calling himself Kotris, an old family name of his — would survive. Kotris knew that as Straxus he had attempted to avoid [[Regeneration|regenerating]], and sent a [[temporal drone]] to prevent Straxus killing himself.
The first time Straxus interfered in his own future timeline was during [[the War]], when his future self became stranded on [[Victorian era|Victorian]] [[Earth]]. The future Straxus had been sent on a mission by his superiors, accompanied by a [[Cwej (species)|Cwej]], but his [[Time Ring|time ring]] failed and he became stranded. Straxus needed to gain his people's attention, and thought the best way to do so was to interfere in history in an obvious way. Rather than assassinating a public figure or starting a war, which might have significantly damaged causality, he collected historical artefacts that should have been discovered in the future. He also attempted to draw another time ring to his time, and managed to attract Bernice Summerfield, but her time ring was set only to work for people matching a specific genetic pattern and he couldn't use it. Straxus wasn't the only one trying to get the attention of a superior through ritual: his [[Cwej (species)|Cwej]] [[Septimus]] was committing murders themed around the number seven, hoping for notice from a "[[Seventh Doctor|Pale God]]". The Cwej's scheme resulted in Straxus's [[regeneration]], but his interference had gotten his people's attention after all: specifically his previous self. The younger Straxus extracted, imprisoned, and interrogated his aborted future counterpart. ([[AUDIO]]: ''[[The Adventure of the Diogenes Damsel (audio story)|The Adventure of the Diogenes Damsel]]'')
Kotris and the Time Controller planned to incubate "[[retro-genitor particle]]s" in a human named [[Molly O'Sullivan]]. They sent [[Dalek]]s after her and the [[Eighth Doctor]], forcing them to spend time together and allowing the retro-genitor particles to latch onto the Doctor's [[Gallifreyan]] [[DNA]]. The particles were then intended to follow that DNA back through history, undoing not just the Doctor's life, but all of Gallifrey's past.
In a different body, 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 condition that Straxus fix his TARDIS. Straxus agreed and gave the Doctor a time ring for his mission.
An [[Straxus (The Great War)|earlier incarnation of Straxus]] modified the retro-genitor particles implanted in Molly to target the Daleks instead of the Time Lords, but in a confrontation with Kotris and the Dalek Time Controller, the Time Controller killed him. This meant he could never become Kotris, and the scheme was entirely undone. ([[AUDIO]]: ''[[The Great War (audio story)|The Great War]]'', ''[[Fugitives (audio story)|Fugitives]]'', ''[[Tangled Web (audio story)|Tangled Web]]'', ''[[X and the Daleks (audio story)|X and the Daleks]]'', ''[[The Death of Hope (audio story)|The Death of Hope]]'')
On the Doctor's return from his mission, Straxus told the Doctor why Lucie was originally taken out of her own time and sent to the Doctor. Straxus then helped the Doctor defeat the [[Cyberman (Mondas)|Cybermen]] on Lonsis before returning to [[Gallifrey]]. ([[AUDIO]]: ''[[Human Resources (audio story)|Human Resources]]'')
Straxus was later sent by the [[Time Lord]]s 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 (audio story)|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 (audio story)|The Vengeance of Morbius]]'')
Yet another Straxus became [[Coordinator]] of the CIA. ([[AUDIO]]: ''[[The Death of Hope (audio story)|The Death of Hope]]'') This was when he next interfered in his own future. His next incarnation became fed up with the morally questionable actions of himself and his people, and allied himself with the [[Dalek Time Controller]]. The Dalek Time Controller helped him rewrite his biodata to remove his Time Lord heritage, so that when they retroactively destroyed the Time Lords the new Straxus — now calling himself Kotris — would survive. Kotris knew that as Straxus he had attempted to avoid regenerating, and sent a [[temporal drone]] to prevent Straxus killing himself. Kotris and the Time Controller planned to incubate "[[retro-genitor particle]]s" in a human named [[Molly O'Sullivan]]. They sent Daleks after her and the Doctor, forcing them to spend time together and allowing the retro-genitor particles to latch onto the Doctor's Gallifreyan DNA. The particles were then intended to follow that DNA back through history, undoing not just the Doctor's life, but all of Gallifrey's past.
The younger Coordinator Straxus was instructed by [[Lord President (Dark Eyes)|the Lord President]] of Gallifrey to send the Doctor to [[France]] during [[World War I]]. Straxus later saved the Doctor and his new companion Molly from a group of Daleks. His TARDIS was attacked by the Daleks and he escaped back to Gallifrey. Straxus attempted to kill himself by throwing himself off a mountain on [[Srangor]], where regeneration was impossible, but was stopped by his future self's temporal drone. Straxus modified the retro-genitor particles implanted in Molly to target the Daleks instead of the Time Lords, but in a confrontation with Kotris and the Dalek Time Controller, the Time Controller killed him. This meant he could never become Kotris, and the scheme was entirely undone.

== Behind the scenes ==
* On the [[12 July (production)|12 July]] [[2011 (production)|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 (audio story)|Human Resources]]'' that they wrote Straxus into ''[[The Vengeance of Morbius (audio story)|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.
