Chessene of the Franzine Grig

Chessene of the Franzine Grig was an Androgum servitor working aboard Space Station Chimera.

Early Life
Chessene was a waitress working for Dastari. She was also a subject of his experimental augmentations, which made her near-human. After becoming augmented Chessene displayed vast intelligence, and gained the power to read both living and dead minds. Her rough Androgum features softened to human-like in appearance, but she retained her savage Androgum instincts and urges.

Later Life
Chessene made a plan to gain a time machine through experimentation on Time Lords. She made an agreement with a group of Sontarans who promptly arrived on Chimera and killed everyone apart from her, Dastari and fellow Androgum Shockeye of the Quawncing Grig. They also failed to kill the Doctor's companion Jamie McCrimmon. Chessene travelled to Spain where they used the captive Second Doctor to search for the ability of time travel which she and Dastari believed was located in a Time Lord's Symbiotic nuclei. Chessene killed the Sontarans with coronic acid when they were no further use. She changed the plan so the Doctor would be turned into an Androgum and tell her where his symbiotic nuclei was located. When the Doctor escaped with Shockeye, Chessene followed him into the town area and eventually found them. She used a gun to force them to return to the house that they had been based in. While there Chessene was disarmed and attempted to escape in the time machine. It had been sabotaged and so exploded, killing her. In death she returned to her normal Androgum form.
