Tegan Jovanka (Dalek duplicate)

From Tardis Wiki, the free Doctor Who reference

A duplicate of the Tegan Jovanka was created alongside Vislor Turlough to accompany a duplicated Fifth Doctor as part of a Dalek plot. They were intended to be sent to Gallifrey where, following Dalek commands, they would assassinate the Time Lord High Council. However, shortly after this plot was revealed to the Doctor by the Supreme Dalek, the dormant duplicates perished when the Dalek Battlecruiser they resided on was destroyed.
