Ishtek

Scout-Ship Commander Ishtek was a Voord whose ship crashed into the sea near Stegmoor in the 20th century.

In 2017, she was reawakened and used energy from the Doctor's TARDIS to contact the Voord survival flotilla. However, the Eighth Doctor made the energy affect her ship, causing its genetic mimicking camouflage to crush the ship beneath sand and rock. Liv Chenka and Matilda Gregson ran her over. She was either killed or returned to suspended animation. (AUDIO: Beachhead)
