Alistair Gryffen

Professor Alistair Gryffen was a scientist specializing in alien technology. He worked for The Department an agency of the totalitarian government of 2050s London.

Biography
Alistair was married and had two children, a son and a daughter in 2040, but they were killed. He then began suffering from Agoraphobia, a condition that keeps him from leaving his home and lab facility. Because of this condition, the Department delivered items of interest for him to investigate. He was also aided in his work by his assistant, Darius Pike.In 2050, His experimentation with a Space-Time Manipulator to bring back his lost loved ones, lead to an accident which brought both the Jixen and K9 to Earth. He studied K9, and helped him to save Starkey. (K9TV: Regeneration)

He let Starkey stay at the Mansion to hide from the Jixen. When the Jixen went to Dauntless Prison, Gryffen monitored K9 as he made his way to the prison. When he was disabled by the Departments defences Gryffen managed to reactivate him by making a familiar sound (the sound of throwing a ball).(K9TV: Liberation)

As he worked on the Space-Time Manipulator for hours on end he dreamed of being reunited with his family again and the limitless possibilities of Time Travel. When a Korven from 2618 came through the STM he kidnapped the Professor so he could extract his knowledge of a Weather-Control device to convert Earth to their standards. He was saved by K9 and the rest of the gang. Later he managed to hack into Starkey's encryption code so that he wasn't a fugitive any more. (K9TV: The Korven)

One night, a trio of non-corporeal lifeforms came through the STM, taking on the appearance of Gryffen's lost family, and manipulating him into doing their bidding. However, due to Starkey convincing him that he, Darius and Jorjie were like family to him, he was able to break free of the apparitions' control, sending them back through the STM. (K9TV: The Fall of the House of Gryffen)

When Korven agents stole the STM, planning to use it to create a portal for their army to enter and attack Earth, Gryffen finally overcame his agoraphobia, making his way to their base and shutting down the STM, an act that resulted in the device's destruction. (K9TV: Eclipse of the Korven)

Personality
Alistair is a classic "absent-minded professor", his work on the Space-Time Manipulator often taking up most of his time. He is a friendly, kind-hearted, trusting invidual, as evidenced by his taking in K9 and Starkey. He dislikes lying, as he considers his role as a scientist to be "the pursuit of truth".
