Time (Fitzaby)

"You are a meddlesome brat sometimes Doctor. Always creating damn paradoxes and anachronisms and destroying time and creating ruptures. Stop effing up the timeline for one second, and listen to me!"

- Mistress Time

Pomona Blanchard, otherwise known as Time, is a companion to the Eleventh Doctor. Originally masquerading as a historian from the 21st Century, Pomona is secretly the personification of Time itself, and holds omnipotent power over the timeline. She stays close to the Doctor whilst taking the Pomona identity to gain information on how to kill the Doctor. She believes that he is a threat to the state of time, and needs to be eradicated.

Time can regenerate like The Doctor and his species, however Time has more control over their regeneration.
