Sistermatic

"It was nessesary to stop the contagen spreading." - Sistermatic to the Doctor & Hex

Sistermatic was an Advanced Level Medical Droid working in the Roarke 279 Research Facility on Bliss. It was unaware of Professor Shimura's experiments. He had implanted the facility staff with the eggs of the Kiseibya. To stop it questioning orders, Shimura tampered with Sistermatics circuits. It believed that the facility staff were infected with a flesh eating disease called Necrotizing Fasciitis. Hex believed it too until he got a closer look at them. The Daleks burst in to exterminate the patients. Despite its brave attempt to protect them, Sistermatic was exterminated.
