Odda

Odda was a member of the Zygon spaceship that crash-landed in Scotland in the 12th century. Odda used the body-print of Sister Lamont. After killing Angus, she was wounded in a forest by UNIT soldiers. She managed to steal a UNIT 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 killed when the Fourth Doctor destroyed the Zygon ship. (TV: Terror of the Zygons)
