Sty

Sty was once an Invader of the mighty Irken Empire. She silently supported Tak, but obeyed Tallest Zim, not that her efforts were recognized by the zealot. Unfortunately, the Irken Empire and its people were destroyed by the Daleks and she learned the Doctor’s pain of being the last of her people. Now she travels with the Doctor and Tysar to undo Omega’s machinations.
