Jeb

Jeb was a fisherman from Zentos 3 who lost his space-pod on a planet in the Myolthen system. He set up camp and rescued the Tenth Doctor and Donna Noble from a raging waterfall after they lost the Doctor's TARDIS in it. The next day, Jeb, the Doctor and Donna became caught in another waterfall. They were rescued by a group of intelligent bears, who led Jeb back to his space-pod. After helping find the Doctor's TARDIS, he set off home in his space-pod. (COMIC: Washed Away!)
