Odda

Odda was a Zygon who impersonated Sister Lamont. She was wounded in a forest by UNIT soldiers. She then stole a jeep and returned to the Zygon ship, assisted by Broton in his human form of the Duke of Forgill and the Zygon posing as Caber. She was likely killed when the Fourth Doctor destroyed the Zygon ship. (TV: Terror of the Zygons)
