                      | Half-Vervoid |  |   History: An artificially engineered species of
            sentient plant, an interesting detail about The Doctor’s encounter
            with the Vervoids is that he knew about it before it happened; The
            Doctor initially learned about the Vervoids when he was on trial
            for his life on the charge of interference in the affairs of the
            universe, using the Matrix to look into his own future and find evidence
            that would clear his name. 
 
  When
            The Doctor faced the Vervoids, it was in the year 2986 on the galactic
            liner Hyperion III, captained by Commodore Travers - a man who had
            previously encountered The Doctor in an unreleased adventure (Although "Instruments
            of Darkness" revealed that it had taken place while The Doctor
            travelled with other future companion Evelyn Smythe) -, carrying
            such diverse passengers as the science trio Professor Lasky and her
            colleagues Bruchner and Doland, The Doctor being drawn to the Hyperion            after the ship broadcast a distress signal from Hallett, a passenger
            on the ship and an investigator that had prior experience of The
            Doctor. 
 
  As
            Hallett had discovered, Lasky and her colleagues had developed a
            genetically -engineered form of sentient plant, known as the Vervoids,
            with the intention that they would eventually replace robots as the
            means of doing tasks that humans were currently incapable of. Unfortunately,
            Lasky failed to take into account that, since all ‘animalkind’ -
            as humans were referred to by the Vervoids - automatically ate plants
            to survive, the Vervoids would be left with an instinctive hatred
            of ‘animal-kind’ and a need to kill them for survival.
            Although initially contained in the Hyperion hydroponics bay, the
            Vervoids escaped when their pods were accidentally opened.

                              | A Vervoid |  |   As the Vervoids roamed the Hyperion’s
				    air ducts, they began to kill the human passengers, collecting them in
				    their ‘lair’ to create a compost heap just as humans collected
				    dead plants, The Doctor gradually piecing together what he was dealing
				    with when examination of an Isolation Room that Lasky had been using
				    revealed that Ruth, another colleague, was mutating into a half-plant
				    life-form after being infected by a speck of Vervoid pollen through a
				    small cut in her thumb. Driven insane by fear of the Vervoids, Bruchner
				    attempted to steer the ship into a black hole to destroy them, but the
				    ship’s course was diverted thanks to two Mogarian passengers after
				    the bridge was infected with marsh gas - Mogarians being able to tolerate
				    the toxic gas - by Doland, his own insanity driving him to ‘save’ the
				    Vervoids in the belief that they could still be used for their original
				    purpose, only to be killed by the Vervoids after The Doctor realised
				    his true intentions. 
 
  With
				    the Hyperion now on a direct course for Earth, The Doctor, Travers
				    and Lasky resolved to destroy the creatures, but were unable to develop
				    a herbicide as the Vervoids had destroyed the necessary chemicals. However,
				    upon examining the Hyperion’s other cargo of rare metals, The Doctor
				    learned that the ship was also carrying vionesium, a rare metal from
				    Mogar that released intense light and carbon dioxide when exposed to
				    oxygenated air. Having lured the Vervoids back to their lair by lowering
				    the lighting and heating in the rest of the ship, The Doctor used the
				    vionesium as ‘bombs’ against the Vervoids, the resulting
				    chemical release causing the Vervoids’ life cycle to accelerate
				    due to the intensity of the chemicals produced, leaving them to wither
				    and die.

                      | A Vervoid |  |   Although the crisis itself was resolved in a straightforward
            manner, The Doctor’s use of it as evidence at his trial only
            left him in further trouble with the court, the Valeyard - the court
            prosecutor, later revealed to be The Doctor’s own dark side
            - taking the opportunity to accuse The Doctor of violating Article
            Seven and committing genocide against the Vervoids. Although The
            Doctor recognised this accusation was essentially legitimate, he
            argued that it couldn’t apply as the consequences of the Vervoids
            surviving would have been the destruction of all life on Earth, the
            Eighth Doctor - having come back in time to visit his former self
            ("The 
      Eight Doctors") - agreeing with his past self’s
            dismissal of the charge on the grounds that the Vervoids were an
            artificial creation rather than a naturally-evolved species and hence
            Article Seven didn’t apply. 
 
  (Given that The Doctor had ‘advance warning’ of
            the events of his confrontation with the Vervoids, it was never expressly
            stated whether he simply allowed events to happen as they should
            because he had to do so in order to prevent a paradox or if he slightly ‘edited’ his
            memory of the confrontation after the trial was over so that he would
            be aware of the essential details without knowing any specifics) |
