Every Classic Doctor Who Companion Ranked From Worst To Best

Katarina is perhaps most famous for being the first of the Doctor's companions to die while travelling with him. She was a poor child from the outskirts of Troy, serving as a handmaiden to Cassandra. When the Doctor, Steven Taylor and Vicki Pallister arrived at Troy, Katarina was sent to spy on them. In particular, she was sent to spy on Vicki, who was taken to be a Greek spy.

She befriended the travellers after Steven was injured by a spear, taking Vicki's place in the TARDIS when the latter elected to remain behind. Katarina set off to see the stars but her travels would be incredibly brief.

While in Troy, she had foreseen her own death. This chilling prediction came to pass during the events of The Daleks' Master Plan. While making sure that the Spar was ready for take-off, she was held hostage in an airlock by Kirksen, who tried to use her as a bargaining tool to force the Doctor to serve him. Katarina, rather than allow herself to be used that way, activated the airlock and blew both of them out into space.

Her death would haunt the Doctor for a very long time to come.
