Mark Seven

Mark Seven was an android member of the Space Security Service. He was stronger and more logical than any human being, with pedantic speech patterns. (BFA: The Destroyers)

Behind the scenes
This version of Mark Seven may be seen as a sort of prototype. Because The Destroyers was unproduced until the 21st century, this version of the character is, confusingly, a prototype of what actually got published first: the Mark Seven of the Anti-Dalek Force, featured in the 1970s Dalek Annuals. Unlike the SSS Mark Seven, the ADF Mark Seven was far more "human". His human colleagues, Reb Shavron and Joel Shaw, for instance, had no idea he wasn't human.
