Katrina Turtle, Known as Kitty, is an 18 year old girl, who is claimed to be the tenth Doctor's Niece. The Doctor and she go of a few journeys, but she isn't really a partner to him. They both agree it's too dangerous for her to join him on his travelings. He only promised to help her find her friend, who went missing.

He does get her birthday presents every year, but after her 11th birthday, he wasn't able to, because of his adventures.
