New Earth (Time of Your Life)

New Earth was a planet where Grant Markham lived, in the city of New Tokyo.

In the year 2191, New Tokyo was transported into a Marston Sphere. Grant used his computer programming skills to defeat a giant robot dinosaur terrorising the city. The Sixth Doctor saved New Tokyo. At the end of the affair, Grant went with him to become his companion. (PROSE: Time of Your Life)
