Grant first met the Doctor in the year 2191 when his home city of New Tokyo on the planet New Earth was transported into a Marston Sphere. Grant used his computer programming skills to defeat a giant robot dinosaur that was terrorising the city. Although the Doctor was able to save New Tokyo, at the end of the story Grant stayed with him to become his companion.

Grant and the Doctor's next adventure was on the planet Agora, Grant's birthplace. Again in the year 2191, they discovered that the Cybermen had been using the planet to gather strong males to use in the cyber-conversion process. Grant met his father, Ben Taggart, who had had Grant sent away from the planet. Taggart was later killed in an unsuccessful attempt to convert him into a Cyberman, watched by Grant. This moved Grant to volunteer to become a Bronze Knight — a resistance group of Agorans who themselves used cybernetic implants to become stronger in order to defeat the Cybermen. He was convinced not to give up his humanity by the Knight's creator, the scientist Maxine Carter. The Cybermen attacked the Bronze Knights and slaughtered them all, but Grant lowered their base's temperature deactivating the Cybermen. The Doctor then destroyed those Cybermen using the cannon from the Cybermen's stolen Selachian warship. This article is about the Doctor Who villains. ...

The circumstances of Grant's parting of ways with the Doctor have yet to be revealed, although the description of an unnamed character that appeared in the short story Repercussions by Gary Russell (in the Big Finish Productions anthology Short Trips: Repercussions) resembled Grant.
