Peri Brown (android)

From Tardis Wiki, the free Doctor Who reference

An android of Peri Brown, along with an android of the Fifth Doctor, was built by Sharaz Jek on Androzani Minor. This allowed Jek to capture Peri and the Fifth Doctor and put the androids in their place.

The two androids were later shot and destroyed by a military firing squad, who believed they were the real Doctor and Peri. (TV: The Caves of Androzani)
